This is a full sheet pan pizza built without wheat flour, using almond flour and psyllium husk powder to create a crust that’s lower in carbohydrates and naturally gluten-free. It still goes through the steps you’d expect from a real pizza — activating yeast, forming a dough, pre-baking the crust, then topping and baking again — just with a different flour base than a traditional dough.

What makes this recipe work is the pairing of almond flour and psyllium husk. Almond flour on its own tends to behave differently than wheat flour, but psyllium husk absorbs moisture and helps bind everything together, giving the crust enough structure and elasticity to hold toppings without falling apart. The result is a crust that’s pleasantly chewy rather than crumbly, with a golden, slightly crisp exterior after baking.

Because it’s baked on a sheet pan rather than shaped into individual rounds, this recipe is built for convenience — one large pizza, evenly baked, that slices cleanly into portions. It works just as well for a regular family dinner as it does for a casual gathering where people want to customize their own section with different toppings.

Mise en Place: Getting Organized Before You Start

This recipe has two active phases — making the dough and building the pizza — so it helps to have everything measured out and ready before you start either one.

For the dough: Have your active dry yeast, salt, olive oil, warm water (around 105–110°F / 40–43°C), almond flour, and psyllium husk powder all measured and within reach. The water temperature matters here — too hot and it can kill the yeast, too cool and it won’t activate properly.

For the toppings: Have your no-sugar-added tomato sauce and shredded mozzarella cheese ready. If you’re using freshly shredded mozzarella rather than pre-shredded, that’s worth doing ahead of time since it melts more smoothly.

Optional toppings: Decide ahead of time what you’re adding — sliced pepperoni, bell peppers, mushrooms, red onion, black olives, spinach, fresh basil, and dried oregano or Italian seasoning are all fair game. If you’re using higher-moisture vegetables, it’s worth sautéing them lightly beforehand so they don’t release excess water onto the crust during baking.

Equipment: A sheet pan, either lightly greased or lined with parchment paper, and a large mixing bowl for the dough.

Understanding the Components

The yeast still does its traditional job here — dissolved in warm water, it becomes active and creates the aroma and subtle texture associated with a real baked pizza crust.

Almond flour forms the base of the dough, contributing a slightly nutty flavor along with healthy fats and protein, in place of refined wheat flour.

Psyllium husk powder is what makes the almond flour dough actually behave like a dough. It absorbs moisture and adds the elasticity that almond flour lacks on its own, helping the crust hold together and support toppings.

Olive oil adds moisture to the dough and contributes to a crisp exterior once baked.

No-sugar-added tomato sauce keeps the carbohydrate content lower while letting the natural tomato flavor lead. It can be enhanced with dried oregano, basil, garlic powder, onion powder, or Italian seasoning without changing the foundation of the recipe.

Mozzarella cheese brings the stretchy, melted texture expected from pizza, along with protein and calcium.

The toppings are where the recipe becomes flexible — pepperoni, vegetables, olives, and fresh basil can all be added according to preference, letting each pizza (or each section of the sheet pan) be customized.

Workflow: Step-by-Step Assembly Strategy

Activate the yeast first. Combine warm water and active dry yeast in a small bowl and let it sit for about 5 minutes, until foamy and bubbly. This step confirms your yeast is alive and working before you commit it to the dough.

Build the dough. In a large bowl, stir together the almond flour, salt, and psyllium husk powder. Pour in the olive oil and the activated yeast mixture, then mix well and knead gently until you have a soft, uniform dough.

Shape the crust. Lightly grease a sheet pan or line it with parchment paper, then press the dough evenly across the pan to form a smooth, even crust.

Pre-bake before topping. This step matters more than it might seem — baking the crust at 190°C (375°F) for 10 minutes before adding sauce and cheese helps set the structure, which prevents the finished pizza from turning soggy once the toppings go on.

Add the toppings. Spread the tomato sauce evenly over the pre-baked crust, sprinkle with mozzarella, and add your chosen toppings.

Bake until golden. Return the pizza to the oven for another 10–15 minutes, until the cheese is fully melted and bubbly and the crust turns lightly golden around the edges.

Rest before slicing. Let the pizza cool for 3–5 minutes before cutting into squares — this short rest helps the cheese set slightly so your slices hold together.

Approved Variations and Swaps

Based strictly on what this recipe supports, here’s where you can adjust:

• Protein toppings: Sliced pepperoni is the classic choice, but this is entirely optional.
• Vegetable toppings: Bell peppers, mushrooms, red onion, and spinach can all be added, either across the whole pizza or in individual sections for different preferences.
• Other toppings: Black olives add a Mediterranean note, and fresh basil is best added after baking for maximum flavor and aroma.
• Extra seasoning: Dried oregano or Italian seasoning can be added to the sauce for a deeper homemade flavor without altering the base recipe.
• Crispier crust: Bake for an extra 2–3 minutes if you prefer more crispness.
• Cheese choice: Freshly shredded mozzarella melts more smoothly than pre-shredded, though either works.

Storage and Reheating

Leftover slices can be stored in an airtight container in the refrigerator for up to 3 days. When you’re ready to eat them again, reheating in the oven or air fryer restores much of the original crispness to the crust, rather than leaving it soft the way a microwave might.

Serving Suggestions

Because this is baked as one large sheet pan pizza, it divides easily into evenly sized squares, which makes it convenient for portioning out family dinners, meal prep lunches, or servings for a gathering where guests might want different topping combinations across the same pan.

Easy Oven-Baked Protein Sheet Pan Pizza (Low-Carb & Diabetic-Friendly)

Description: A full sheet pan pizza built on an almond flour and psyllium husk crust, topped with no-sugar-added tomato sauce, mozzarella cheese, and your choice of toppings — a lower-carb, gluten-free alternative to traditional pizza.

Duration:

• Pre-bake: 10 minutes
• Final bake: 10–15 minutes
• Rest before slicing: 3–5 minutes

Ingredients:

For the Pizza Base

• 2¼ teaspoons active dry yeast
• 1 teaspoon salt
• 1 tablespoon extra virgin olive oil
• 1 cup warm water (about 105–110°F / 40–43°C)
• 2 cups almond flour (low-carb flour alternative)
• 2 tablespoons psyllium husk powder (helps bind and improve texture)

For the Pizza Topping

• ½ cup no-sugar-added tomato sauce
• 1½ cups shredded mozzarella cheese

Optional Toppings

• Sliced pepperoni
• Bell peppers
• Mushrooms
• Red onion
• Black olives
• Spinach
• Fresh basil leaves
• Dried oregano or Italian seasoning (optional, for extra flavor)

Instructions:

1. In a small bowl, combine the warm water and active dry yeast. Let it stand for about 5 minutes, or until the mixture becomes foamy and bubbly.
2. In a large mixing bowl, stir together the almond flour, salt, and psyllium husk powder. Pour in the olive oil along with the activated yeast mixture. Mix well, then knead gently until a soft, uniform dough forms.
3. Lightly grease a sheet pan or line it with parchment paper. Press the dough evenly across the pan, creating a smooth and even pizza crust.
4. Bake the crust in a preheated oven at 190°C (375°F) for 10 minutes until it begins to set.
5. Spread the no-sugar-added tomato sauce evenly over the crust. Sprinkle with shredded mozzarella cheese and finish with your preferred toppings, such as pepperoni, vegetables, olives, or fresh basil.
6. Return the pizza to the oven and bake for an additional 10–15 minutes, or until the cheese is fully melted, bubbly, and the crust turns lightly golden around the edges.
7. Allow the pizza to cool for 3–5 minutes before slicing into squares. Serve warm.

Notes:

• For a crispier crust, bake the pizza for an extra 2–3 minutes.
• Freshly shredded mozzarella melts more smoothly than pre-shredded cheese.
• Add fresh basil after baking for the best flavor and aroma.
• Store leftovers in an airtight container in the refrigerator for up to 3 days and reheat in the oven or air fryer.
