You are in for a pizza treat! This portobello pizza is made with… you guessed it, portobello mushrooms. These large caps are absolutely perfect for stuffing with traditional pizza toppings. I’ve topped this portobello mushroom pizza with sauce, cheese, and pepperoni, but I’m also sharing a ton of ideas below. These are so easy to customize, or put out toppings and let everyone top their own.

We have low carb pizza night at least once a week at our house. It never gets boring, because first of all… pizza!! And second, we switch it up a lot! The classic keto fathead pizza crust is still a family fave, but there’s also cauliflower pizza crust , pizza bowls , eggplant pizzas , and even cauliflower pizza casserole . And, these portobello pizzas are part of the rotation as one of my favorite keto stuffed mushrooms recipes.

Why You Need My Portobello Mushroom Pizza

• Classic pizza flavor
• Soft mushrooms and cheesy toppings
• Just 10 minutes to prep
• Cooks in 20 minutes
• Naturally low in carbs, keto, and gluten-free

Ingredients & Substitutions

Here I explain the best ingredients for my pizza stuffed portobello mushroom recipe, what each one does, and substitution options. For measurements, see the recipe card .

• Olive Oil Spray – Use a spray to get an even and light coating of olive oil on the baking sheet and the mushrooms. If you don’t have it, you can just drizzle or brush on olive oil instead.
• Portobello Mushrooms – Choose large portobello mushroom caps that are more concave and have taller sides work best to hold the toppings.
• Sauce – I used marinara sauce here, but pizza sauce is also a great choice. Buy store-bought (I look for versions without added sugars like this one ), or make your own sugar-free marinara sauce or keto pizza sauce .
• Mozzarella Cheese – Use shredded for convenience or shred your own. Fresh mozzarella is also fine, but will release more moisture.
• Pepperoni – I love classic pepperoni pizza, but you can also try some of the other topping ideas below.

How To Make Portobello Mushroom Pizza

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. Prep. Preheat the oven. Coat a baking sheet with a layer of olive oil spray. Scrape out the gills of the mushrooms with a spoon.

TIP: If you like, you can pre-cook the mushrooms in the oven first.

Doing this helps to get rid of the extra moisture before adding toppings, but I often skip this step for less work. If you do roast them first, drain, then add toppings and bake again. If you skip this step, know that they can release a lot of water, but you can just drain the extra liquid from the pan afterward instead.

1. Season. Place mushrooms on a rimmed baking sheet (stem side up). Spray with olive oil and sprinkle with sea salt.
2. Assemble. Top each mushroom with sauce, cheese, and pepperoni.

1. Bake. Place in the oven until the cheese is bubbly and the mushrooms are soft. If you like, you can top with grated parmesan cheese at the end.

My Recipe Tips

• Use a thick sauce. A thin sauce will make the mushroom more watery.
• Spread sauce carefully. Don’t put the sauce all the way to the edge of the mushroom cap, as it can run off while cooking.
• Choose the best mushroom shape. Look for mushroom caps that are concave so that they hold the fillings in better. If yours are very flat, it may be better to roast the mushrooms with olive oil for 15 minutes first, then pat any excess moisture with paper towels, add toppings, and bake for about 5 more minutes to melt the cheese.

Topping Ideas

Wondering about what to put on your portobello mushroom cap pizza? Try some of these topping ideas:

• Meat Lover’s – Meat in every bite! Top your mushroom with pepperoni, Italian sausage, ham, and bacon . Season with red pepper flakes if you want to add a little heat.
• Veggie Lover’s – You can go so many ways with veggie pizzas, but a classic veggie pizza has peppers, onions, cherry tomatoes, and black olives. If you’d like to try some others, add garlic, baby spinach, artichoke, broccoli, or extra mushrooms. For watery vegetables, it’s best to pre-cook them first.
• Hawaiian – Similar to my Hawaiian pizza bowl , top the mushroom with cheese, ham, and diced pineapple.
• BBQ Chicken – Top the mushroom with shredded chicken tossed in sugar-free bbq sauce , shredded cheese, diced onions, and cilantro.
• Margherita – This simple classic is made with tomato sauce, fresh mozzarella and fresh basil leaves.
• White Pizza – Just like my chicken crust pizza , top the mushroom with alfredo sauce , spinach, red onion, and mozzarella cheese.
• Add a finishing sauce – For a simple flavor boost, add a drizzle of balsamic glaze to your pizza.

Maya’s Recipe Notes

Serving size: 1 stuffed mushroom

• Tips: Check out my recipe tips above to help you avoid watery mushrooms, keep the sauce from running off, and make sure your toppings stay put!
• Store: Keep leftovers in the fridge for 3–4 days.
• Reheat: Bake at 350 degrees F to warm them up.
• Freeze: Mushrooms don’t freeze well—better to make a smaller batch!
• Note on the recipe: If you’d like, you can pre-bake the mushrooms for 15-20 minutes before adding toppings. Drain, then add toppings and bake again. They turn out less watery this way.

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
• Most fruit – Such as apples, bananas, and grapes

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.
