Ingredients You Will Need
This recipe has two simple parts: the low-carb dough and the cheesy filling. Here is what goes into each, along with a few notes on substitutions.
For the Fathead Dough
- 2 cups shredded mozzarella cheese
- 2 ounces cream cheese, cubed
- 1 cup almond flour
- 1 large egg
- 1/4 teaspoon salt
For the Filling
- 1/2 cup low carb marinara sauce, plus more for dipping
- 1 cup shredded mozzarella cheese
- 3 ounces sliced pepperoni
- 1/4 cup ricotta cheese
- 2 tablespoons grated parmesan cheese
- 1 teaspoon Italian seasoning
For the Egg Wash
- 1 egg, beaten
- 1 tablespoon water
Ingredient notes and substitutions: Almond flour gives the dough its structure, and finely ground blanched almond flour works best. If you need a nut-free version, coconut flour can be used, but reduce the amount to about a third since coconut flour absorbs far more liquid. Ricotta can be swapped for cottage cheese in a pinch, and any low-sugar marinara sauce will work as long as you check the label for added sugar. Feel free to swap pepperoni for cooked Italian sausage, diced ham, or sautéed vegetables if you want a different flavor profile.
Step-by-Step Instructions
Step 1: Make the dough. In a microwave-safe bowl, combine the shredded mozzarella and cream cheese. Microwave in 30-second bursts, stirring between each, until fully melted and smooth, about 60 to 90 seconds total.
Step 2: Bring the dough together. Add the almond flour, egg, and salt to the melted cheese mixture. Stir quickly with a spatula or your hands until a uniform dough forms. If the dough cools too much and becomes stiff, microwave for another 10 to 15 seconds to soften.
Step 3: Divide and roll. Preheat your oven to 425°F. Divide the dough into 4 equal portions. Place each portion between two sheets of parchment paper and roll into a circle about 6 inches across and 1/8 inch thick.
Step 4: Add the filling. Remove the top sheet of parchment. On one half of each dough circle, layer a spoonful of marinara sauce, a portion of the shredded mozzarella, a few slices of pepperoni, a dollop of ricotta, and a sprinkle of Parmesan and Italian seasoning. Leave a small border around the edge clear of filling.
Step 5: Fold and seal. Use the parchment paper to help fold the empty half of the dough over the filling, forming a half-moon shape. Press the edges firmly together with your fingers, then crimp with a fork or roll the edge over itself to seal tightly.
Step 6: Vent and brush. Transfer the calzones to a parchment-lined baking sheet. Cut two or three small slits in the top of each one to let steam escape. Brush the tops generously with the egg wash for a golden, glossy finish.
Step 7: Bake. Bake for 18 to 22 minutes, or until the calzones are deep golden brown and firm to the touch. Let them rest on the pan for 5 minutes before slicing, since the cheese filling will be extremely hot.
Tips for Best Results
Keep your filling light on liquid. Excess marinara sauce or watery ricotta can make the dough soggy or cause it to tear during folding, so drain any wet ingredients first and use sauce sparingly. Work with the dough while it is warm, since fathead dough stiffens as it cools and becomes harder to shape. If it firms up too much while you are working, a quick 10-second reheat in the microwave will loosen it right back up.
Seal the edges well. A loose seal is the most common reason filling leaks out during baking, so take an extra moment to crimp firmly and double-check for any thin spots or gaps. Cutting a few small vents in the top is not optional either, since it keeps steam from building up and blowing the seams open in the oven.
For an extra crisp bottom crust, bake the calzones directly on a preheated pizza stone or a baking sheet that has been warming in the oven, rather than a cold pan.
Storage and Reheating
Let leftover calzones cool completely before storing. Keep them in an airtight container in the refrigerator for up to 4 days. To reheat, warm them in a 375°F oven or air fryer for about 8 to 10 minutes until heated through and crisp again. Microwaving works in a pinch, but the crust will turn soft rather than staying crisp.
To freeze, wrap each baked and fully cooled calzone individually in plastic wrap, then place in a freezer-safe bag for up to 3 months. Reheat from frozen in a 375°F oven for 20 to 25 minutes, or thaw overnight in the refrigerator first and reheat for about 10 minutes.
Frequently Asked Questions
Can I make keto calzones ahead of time? Yes. You can assemble the calzones completely, then refrigerate them unbaked for up to a day before baking, or bake them fully and reheat later in the week.
Why did my dough crack or fall apart? This usually happens when the cheese mixture cools too much before the almond flour and egg are added. Work quickly while the cheese is still warm, or briefly reheat the dough if it becomes stiff and crumbly.
Can I use coconut flour instead of almond flour? Yes, but use about a third of the amount called for, since coconut flour is far more absorbent. Start with 3 tablespoons plus 2 ounces of extra cream cheese and adjust as needed.
Are keto calzones freezer-friendly? Absolutely. Baked calzones freeze well for up to 3 months and reheat nicely straight from frozen in the oven.
What can I use besides pepperoni? Cooked Italian sausage, diced ham, shredded chicken, or sautéed mushrooms and spinach all work well as fillings.
