Keto Crustless Pizza

Pizza is one of my favorite foods. I could eat it several times a week, to the disappointment of my family as I’m not sure they share the same sentiment. I’ve tried all kinds of keto pizzas, yet I find myself most often just eating the toppings off pizza for the sake of convenience.

Recently I saw that several national chains like Papa Murphy are selling a crustless pizza, which is a fabulous idea. I figured it would be easy enough to make at home and more cost-effective. Plus, I wouldn’t have to go out and pick it up.

A  homemade keto crustless pizza is a great option because there is no waste, and you can control all of the ingredients. When I tried my hand at making it myself, it turned out amazing, and it was so quick and easy! In fact, I’ve made it at least four times in the past two weeks and enjoyed leftovers for several other days.

Can you eat pizza toppings on keto?

The short answer is yes, but it depends. The majority of carbs in pizza are in the crust, so just eating the toppings could be a great alternative. However, it is very likely that the pizza sauce has sugar in it and is higher in carbs. If you are super strict keto, you may want to avoid it. If not, you could always request light sauce. Most pizza restaurants, with the exception of Chicago style pizzas, don’t use a lot of sauce, so for me, I’m okay with eating toppings off the pizza.

What is Crustless Pizza?

Crustless pizza is just as it sounds. Basically, you omit the crust but add all of the other ingredients and bake. It makes a low carb alternative to regular pizza that is both simple to make and delicious.

Is Crustless Pizza Keto?

Crustless pizza is most definitely keto-friendly. I used an organic low carb marinara sauce, which only added three net carbs to the entire recipe, and there is no sugar in the sauce. You can make it with your favorite toppings, as it is incredibly versatile.

What size cast iron skillet did I use?

I used this Lodge 10.25″ cast iron skillet. I love that it goes from the stovetop to the oven with ease. Cast iron skillets are also very affordable, and they last forever. I have some cast iron skillets that are over 50 years old that were my grandmothers.

You can find this 10.25 cast iron skillet on Amazon. It is preseasoned and generally less than $15, although Amazon’s prices do fluctuate.

Can I use a regular baking dish?

A cast-iron skillet is not necessary to make this recipe. Any baking dish or oven-safe skillet will work

What keto-friendly pizza sauce should I use?

I used a low carb marinara sauce for pizza sauce when I made this crustless pizza. Since there is no crust to absorb the sauce, you don’t need as much. I only used a half cup of sauce for a 10.25 inch cast iron skillet. A little bit goes a long way.

If you aren’t sure which sauce to look for at the grocery store, I’ve listed several of our favorites below, along with the net carb count. Make sure to look for a sauce that is sugar-free, meaning no added sugar in the ingredients.

To make this recipe cook faster, I heated the marinara sauce on the stove first before adding the toppings. If you don’t have an oven-safe skillet for this recipe and are using a baking dish, heat the marinara sauce first in the microwave before adding the shredded cheese and toppings.

If you had rather, skip preheating the sauce add all the ingredients to the baking, dish, and bake for approx 20 minutes on the middle rack of the oven.

As I mentioned, I prefer the toppings under the mozzarella cheese then a small sprinkling of cheese on top. You can change up this recipe and personalize it depending on your favorite pizza toppings. My favorite toppings are pepperoni, ground beef, and bacon. Sometimes we add a few veggies as well for added bulk.

How to bake crustless pizza

Once the keto crustless skillet pizza is assembled top with Italian seasoning, then pop it in the oven so that all of the toppings can get hot and the mozzarella cheese bubbles and browns.

    I appreciate the step by step. I’ve been doing something similar in a silicon pan, but have started with baking a layer of cheese, then light sauce, cheese, toppings, and a light dusting of cheese and seasonings. It’s worked well. I’ll have to give this method a try, though.

    1. The number of servings is located at the top of the recipe card. I divide it evenly based on that number.

    Cant wait to try this. Just got some mini iron pans from Pampered Chef which will be perfect since I like SUPREME and hubby likes all meat!

    1. The number of servings is listed at the top of the recipe card. This recipe makes 3 servings and the nutritional info is per serving.

  3. A guy who owned his own Italian restaurant taught me how to make pizza, years ago, and he always laid the sauce first, then sprinkled oregano, garlic powder, black pepper and grated parmesan on the sauce, followed by the toppings. That way, the seasonings flavor the sauce and toppings but don’t get scorched by being on top exposed to high heat.
    Same principle applies to things like spinach, that I prefer not to scorch.
    Hope that helps someone.

    OMG! Better than I expected! Didnt have marinara so used Mezzata tomato and basil sauce (Mmmm, so good!). Did 1/2 cup because 1/4 didnt cover my iron pan at all. Topped with basil not Italian seasoning, because I love basil. Was able to cut it into slices and carefully transfer to a plate which surprised me but did use a spoon to eat it. Lol! Bottom line…I got my pizza fix! Thank you!

    Really fun and easy to make! Followed the instructions exactly, even cooked a little longer because I wanted it super crispy. Edges were crispy, but inside was just a delicious mess lol. Might try baking the cheese first next time till it’s super crispy and then bake with cheese and toppings. Thanks for the recipe and for the nutrition card!
