After years of sizzling my classic chicken fajitas and shrimp fajitas on the stovetop (and even trying Instant Pot steak fajitas ), I decided it was time to shake things up with a sheet pan version. (Okay, let’s be real, I had a night I wanted something even easier .) My sheet pan fajitas simplify the process without skimping on the flavors I love in the traditional version. Just toss your protein, bell peppers, and onions with some vibrant spices and let the oven do the work. Hands-off method accomplished! And while I opted for sheet pan steak fajitas this time, you can totally do it with chicken or shrimp as well.

Why You Need My Sheet Pan Fajitas

• Tender, juicy protein and veggies with fajita flavor – Choose steak, chicken, or shrimp! Cooking everything together gives it this incredible caramelized, roasted flavor, while my homemade fajita seasoning makes this dish pop. And I’ve got just the right cook time for juicy results!
• Hands off method – My regular steak fajita recipe is already quick, but you’re still stuck by the stove. With my easy sheet pan fajitas, your oven takes care of it.
• Quick and easy one pan meal – Just toss 6 simple ingredients on a pan (and maybe a shower of cilantro if you’re up for it!), and you’re less than 30 minutes away from a fabulous meal.
• Fresh and healthy – These fajitas are not only tasty; they’re also packed with protein and veggies, and naturally gluten-free. It’s a meal you can feel good about serving for your family.

1. Preheat the oven to 400 degrees F (204 degrees C). Pat the steak dry with paper towels.
2. Slice the steak (or chicken) into thin strips, going against the grain, about 1/4 inch thick for steak or 1/2 inch thick for chicken. If any of the pieces are too long, slice them in half lengthwise.
3. Add the steak or chicken, sliced peppers and onions, olive oil, fajita seasoning and lime juice to a large mixing bowl. Toss well to combine (tongs work well for this).
4. Transfer the steak (or chicken) and vegetables to a large sheet pan and spread into an even layer. (If your baking sheet doesn’t have a great nonstick surface, spray with cooking spray first.)
5. Roast sheet pan fajitas in the oven for 15-18 minutes , until the steak (or chicken) is browned and the vegetables are tender. (Don’t cook for too long, otherwise the steak will dry out and get tough.)
6. Remove from oven and toss with fresh cilantro before serving.

Ingredients & Substitutions

Here I explain the best ingredients for sheet pan steak fajitas, what each one does in my recipe, and substitution options. For measurements, see the recipe card .

Choose Your Protein:

You’ve got a few options:

• Steak – I rotate flank steak, skirt steak , and sirloin steak , as these won’t break the bank and really soak up all those fajita flavors. You could splurge on a filet mignon or New York strip , but honestly, I think that’s a bit of a waste of a pricey steak.
• Chicken – For sheet pan chicken fajitas, I recommend boneless skinless chicken breasts because they slice up nicely. But you can use boneless chicken thighs if you like! The cook time will be similar to steak.
• Shrimp – Shrimp cooks about 5 minutes faster than the other options above.

Other Ingredients:

• Olive Oil – Avocado oil’s a great swap if you’re out of olive oil or just want to mix things up a bit.
• Bell Peppers – A mix of red and green bell peppers brighten up the dish with their colors. Yellow or orange are great, too — feel free to pick your favorites.
• Onion – I went with a yellow onion this time, but a white or red onion will do the trick just as well. Use whatever you’ve got!
• Fajita Seasoning – I make my own homemade fajita seasoning , which is a 5-minute combination of chili powder, garlic powder, onion powder, paprika, cumin, dried oregano, cayenne pepper, and sea salt. You can substitute store bought seasoning , or even taco seasoning . If your seasoning doesn’t contain salt, add 1 teaspoon of salt.
• Lime Juice – I use fresh lime juice because I always want fresh lime wedges for serving, but bottled lime juice can step in if that’s what you have handy.
• Fresh Cilantro – Totally optional, but I always like to top my sheet pan fajitas with a generous sprinkle for a touch of freshness and flavor.

How To Make Sheet Pan Fajitas

I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card .

1. Slice. Cut the steak (or chicken) into thin strips, going against the grain. A good thickness is about 1/4 inch thick for steak or 1/2 inch thick for chicken. If any of the pieces are too long, slice them in half crosswise. Slice the onions and bell peppers into strips as well.
2. Season. Add the steak (or chicken), sliced peppers and onions, olive oil, fajita seasoning and lime juice to a large mixing bowl. Toss well to combine.
3. Arrange. Transfer steak and vegetables to a large baking sheet and spread in an even layer. (If your baking sheet doesn’t have a great nonstick surface, spray with cooking spray first.)

1. Bake. Cook your sheet pan fajitas in the oven, until the steak is browned and the vegetables are tender. Don’t forget that sprinkle of fresh cilantro at the end!

My Recipe Tips

• If you’re using steak, freeze it for 15 minutes for easier slicing. This is not required, but freezing the meat briefly makes it firmer, so it’s easier to slice thinly. For chicken I skip this step, since the slices don’t need to be so thin.
• Slice your steak or chicken against the grain. This little trick breaks up the muscle fibers, making each strip super tender. I go for about 1/4 inch thick for steak and a bit thicker for chicken to keep things juicy.
• Choose an extra large bowl. You need a big one for all these ingredients to fit!
• Don’t want to wash an extra bowl? You can season your meat and veggies right on your sheet pan instead, and use tongs to coat everything evenly. I just find it easier to mix in a bowl.
• Space out the fajitas on the sheet pan. If they’re too crowded, they’ll steam instead of getting those tasty, caramelized edges.
• Drain the pan if needed. If you notice a lot of liquid in the pan 5 minutes before the time is up, drain it and continue roasting.
• For extra browning, place under the broiler. I don’t usually need to do this (you can see in my pictures that the steak and veggies are already nicely browned without it), but if you want more browning, stop baking a little sooner and broil for 2-3 minutes at the end.
• Be careful not to overcook. I always use the protein as the doneness indicator, not the veggies. You want your steak, chicken, or shrimp to be juicy and tender, whereas vegetables have a wider range where they still taste great.

Storage & Meal Prep

• Store: Keep your leftovers in an airtight container in the fridge for up to 4 days. The steak won’t taste as good as fresh, but they’re still delicious!
• Meal prep: I cut the veggies ahead all the time, and they store well in the fridge for up to a few days. You can cut the steak in advance as well, but it might brown. If you want to cook the entire dish ahead, I recommend chicken over steak, as it tastes better reheated.
• Reheat: My favorite way to reheat sheet pan fajitas is on… you guessed it, a sheet pan again! It takes about 10 minutes at 350 degrees F. You can also toss them in a skillet if you like.
• Freeze: After cooling to room temperature, arrange the meat and veggies on a baking sheet lined with parchment paper, and freeze for 1-2 hours, until solid. Transfer to a zip lock bag and keep in the freezer for up to 3 months.

Serving Ideas

You can probably guess that you can serve sheet pan fajitas the same way as regular ones, but I actually have a few ways I serve them:

• Tortillas – The classic choice! For my family we usually serve a mix of corn tortillas and either jicama tortillas , almond flour tortillas , or cheese taco shells . Top ’em with shredded cheese, sour cream, avocado (or guacamole !), fresh cilantro, and a squeeze of lime. My fresh salsa , restaurant-style salsa , or creamy avocado salsa verde also pair nicely.
• Bowls – Serve them over a bed of rice (or cauliflower rice ) with any of the toppings above. I love this version over my cilantro lime cauliflower rice with a dollop of taco slaw .
• Salad – Swap the taco meat in my taco salad with these sheet pan fajitas instead. You can also tuck them into a lettuce wrap for another light option.
• Cheesy – Not traditional, but my husband likes this. Sprinkle shredded cheese over the meat and vegetables in the last few minutes of cooking to let it melt, and just serve by itself (or over a bowl, above). It’s a bit like my Mexican taco skillet , but in sheet pan form.

If you’re serving these fajitas on a weekend, start your meal with my Mexican shrimp cocktail — and don’t forget the skinny margaritas !

The Basic Keto Meal Formula

Eating keto doesn’t have to be complicated! While there are plenty of delicious easy keto recipes to choose from, you don’t even have to cook from a recipe to get started.

Simply follow the keto cheat sheet formula of protein + veggie + fat for your meals.

Be sure to choose a moderate amount of protein, only low carb vegetables (mostly ones that grow above ground), and generous fat to attain an optimal macro ratio. That’s approximately 60-75% of calories from fat, 20-25% protein, and 5-10% from carbohydrates. The table below will give you ideas for what to choose.

Understanding Macros

Macros are macronutrients for short. They include fat, protein, and carbohydrates.

You can calculate your own macros using the macro calculator , but the macro keto cheat sheet below will explain how to look at macros when following a keto lifestyle.

Carbs Are A Limit.

Keeping carbs low is what gets you into ketosis and keeps you there. Ketosis means that you’re using fat as your primary energy source instead of sugar, and requires keeping carbs very low.

A good starting point is 20-25 grams net carbs per day, but you can experiment after a few weeks to see if your body stays in ketosis at higher levels. People who are very active may be able to do more and stay in ketosis, up to around 50 grams per day.

“Carbs are a limit” means that you set a limit for how many carbs to eat per day and don’t exceed it. You don’t have to hit that limit, so if you’re under that’s okay, just don’t go over. Ideally most of your carbs would come from low carb vegetables, and if you’re eating enough veggies, you’ll usually get close to the limit naturally.

A common misconception is that reaching ketosis requires a certain macro ratio, but it’s really only restricting your carb intake that gets you there [ * ]. In the absence of sufficient carbs to use as energy, the body will switch to using fat as fuel. This is called the metabolic state of ketosis.

Protein Is A Goal.

Protein is made up of amino acids, the building blocks of all our cells. It’s a crucial for keeping our muscles strong and for many cellular functions [ * ].

“Protein is a goal” means that you always want to eat enough protein to reach the goal each day, but not exceed it too much. You want enough for your needs, but excess protein can trigger gluconeogenesis, which is protein being converted to sugar [ * ] and can kick you out of ketosis.

Fat Is A Lever.

Fat is the primary macronutrient in a keto lifestyle, because being in ketosis means that fat is your primary fuel source. Fat as a fuel source will come from your food, and if you are losing weight, from your body.

A big advantage of a keto lifestyle is the high fat intake. It keeps you full and satisfied, making it easier to stick to, and using it as the primary fuel source makes it easier on your body to burn body fat, with a lower chance of breaking down your muscle (provided you get enough protein).

Aside from reaching your protein goal and limiting your carbs, the remainder of your calories on a keto diet comes from fat.

Don’t fear fat – it’s your main energy source on keto, and getting enough of it trains your body to use fat for fuel instead of sugar. That means that as long as you are not overdoing your overall calorie intake, you’ll efficiently burn your body fat for fuel as well.

“Fat is a lever” means that you can increase or decrease your fat intake depending on your goals and hunger levels. Increase it (along with exercise) to gain muscle, or decrease it to lose weight.

Keto Food Swaps

One of my favorite challenges is creating recipes, or just discovering, keto food swaps. These are delicious keto replacements for traditionally high-carb or high-sugar foods.

So, I created this keto diet cheat sheet with all the swaps in one place! I also have more keto food swaps in my Easy Keto Cookbook .

Keto Food List

When looking for a keto cheat sheet printable, the most-requested information is a keto food list.

The great thing is that keto doesn’t have to feel restrictive. It’s incredibly satisfying and there’s such a wide variety of foods you can eat!

Foods To Eat On Keto

• Leafy greens – Such as spinach, chard, and lettuce.
• Above-ground veggies – Such as peppers, zucchini, and cauliflower.
• Full-fat cream & cheese – Such as heavy cream, sour cream, and full-fat hard cheeses.
• Natural meats – Such as beef, lamb, and pork.
• Berries – Such as raspberries, blackberries, and strawberries.
• Avocados
• Unsweetened nut milks – Such as almond milk and coconut milk.
• Almond flour and coconut flour
• Eggs
• Healthy fats – Such as coconut oil, avocado oil, olive oil and butter.

Foods To Avoid On Keto

• White flour & sugar
• Rice & grains – Such as barley, wheat, and corn.
• Milk & yogurt – Such as fruit on the bottom yogurt, sweetened Greek yogurt, and all milk.
• Cereal
• Processed food – Such as granola bars, candy

Electrolyte Basics

Getting enough electrolytes is crucial for anyone, but especially so on a keto diet. The reason is that ketosis has a diuretic effect, which increases excretion of water and electrolytes, especially sodium [ * ]. This is often the cause of the keto flu.

For more details on electrolytes and avoiding keto flu, check out the full keto flu guide here .

The important thing to know about electrolytes is that replenishing them will keep keto flu away and keep your body functioning well. I always recommend an electrolyte drink and whole food sources of anything your body needs before resorting to supplements, so I made a list of what to eat to get each of the 3 major electrolytes – sodium, magnesium and potassium.

Here’s your keto diet cheat sheet for getting electrolytes from food:

Keto Diet Types

People follow a keto lifestyle for different reasons. Some do it just to lose weight, others are after better overall health, increased energy, and reduced inflammation.

Strictly speaking, the defining factor of a keto diet is the metabolic state of ketosis, which is achieved by restricting carbs. However, many people (myself included) also reduce or eliminate processed, inflammatory, or low-nutrient foods.

Below is your keto cheat sheet summary of the different ways that people follow keto. You choose what works best for your goals and lifestyle!

• Strict Keto – Up to 20-30g net carbs daily, count all calories and macros, and eat clean, unprocessed foods.
• Lazy Keto – Up to 20-30g net carbs daily, and track only net carbs OR eat keto foods without tracking.
• Dirty Keto – Up to 20-30g net carbs daily, with “if it fits your macros” approach including processed foods.
• Low Carb – Up to 50-100g net carbs daily, less strict.
