  • 1/2 cup marinara sauce or pizza sauce See low carb marinara sauce suggestions in the post.
  • 1 ½ cups mozzarella cheese
  • 1/2 cup browned sausage (or ground beef)
  • 1 tbsp green pepper, chopped
  • 16 pepperonis
  • 1/4 tsp Italian seasoning


  • Preheat oven to 400 degrees.
  • Add 1/2 cup marinara or pizza sauce to the bottom of a cast-iron skillet and heat on the stove until sauce is bubbling. If you are using a baking dish instead of an oven-safe skillet, warm the marinara sauce in the microwave first. This step reduces the baking time later.
  • Sprinkle mozzarella cheese on top, reserving 1/4 cup.
  • Add toppings to the crustless pizza.
  • Sprinkle the remaining mozzarella cheese on top and Italian seasoning.
  • Bake on the top rack of the oven until the mozzarella cheese begins to bubble and turn brown (approx 5-10 minutes depending on the oven and how browned you like the top of your pizza).



The nutritional information provided is based on using a low carb marinara sauce with 3 net carbs per 1/2 cup serving. The toppings included in the nutritional information are listed in the ingredients above. I used ground beef instead of sausage.
