If you’ve been craving pizza but want something lighter, this high protein crustless pizza is cheesy, comforting, low carb, and on the table in about 30 minutes—no dough, no fuss, just pure flavor.

What Is High Protein Crustless Pizza? (And Why I Love It So Much)

This high protein crustless pizza is exactly what it sounds like: all the best parts of pizza—the melty cheese, savory sauce, and your favorite toppings—baked into a high protein, no crust high protein pizza “casserole” that eats like a deep-dish slice… just without the actual crust.

It’s a low carb high protein pizza that leans heavily on eggs, Greek yogurt, and cheese for its base, rather than flour or dough. Think frittata meets lasagna meets your favorite Friday night delivery—only this version is a bit kinder to your blood sugar and your macros.

I started making this healthy crustless pizza a few years ago when my oldest son got serious about lifting at the gym and wanted a gym friendly pizza recipe that wouldn’t blow his protein goals. I wanted something I could feel good about serving the whole family, something I could throw together after work without kneading dough or waiting for rise times.

Now it’s one of our regulars: a high protein oven baked pizza that’s perfect for busy weeknights, casual Sunday dinners, and even meal prep. I often bake two pans at once and stash slices for a high protein meal prep pizza that reheats beautifully for lunches all week.

If you’re working on weight loss, this doubles as a crustless pizza for weight loss—lots of volume, high protein, and relatively low calorie compared to traditional pizza. If you’re just a pizza lover who wants something a bit lighter, you’re in the right place too.

Ingredients for High Protein Crustless Pizza

Here’s what you’ll need for this crustless high protein pizza recipe. I’ll include some notes and substitutions, because I know we don’t always have everything on hand.

For the high protein “base”

• 8 large eggs
  • (Room temperature if you can; they whisk more easily and bake more evenly.)
• 1 cup plain Greek yogurt, 2% or whole milk
  • (Whole milk gives extra creaminess and richness; 2% is a great balance of texture and calories.)
• 1 cup part-skim ricotta cheese
  • (Adds a lasagna-like texture. Cottage cheese can work too—just blend it for a smoother result.)
• 1 cup shredded part-skim mozzarella cheese
  • (You can use a pizza blend, but mozzarella is classic and gives a great stretch.)
• ¼ cup grated Parmesan cheese
  • (Freshly grated if possible; the nutty flavor really boosts the savory notes.)
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon dried Italian seasoning
  • (Or a mix of dried basil, oregano, and thyme.)
• ½ teaspoon kosher salt
• ¼ teaspoon black pepper

For the “pizza” layer

• ¾–1 cup pizza sauce or thick marinara
  • (Look for a no-sugar-added brand if you’re watching carbs. Rao’s and Primal Kitchen are popular choices.)
• 1½ cups shredded part-skim mozzarella cheese, divided
• ½ cup turkey pepperoni slices (about 2 ounces)
  • (You can use regular pepperoni, chicken sausage slices, or plant-based pepperoni if you prefer.)
• ½ cup cooked, crumbled lean Italian turkey sausage or chicken sausage (optional but great for protein)
• ½ cup sliced mushrooms
• ½ small red onion, thinly sliced
• ½ red or green bell pepper, thinly sliced
• 2 tablespoons sliced black olives (optional)
• 1 teaspoon dried oregano (for sprinkling on top)
• Pinch of red pepper flakes (optional, for a little heat)

You can absolutely treat the toppings section as a “choose your own adventure” situation—this is a flexible healthy crustless pizza base that plays nicely with a lot of flavor combinations.

A Quick Peek at the Finished Dish

Just look at that—bubbly cheese, pepperoni edges crisped just right, and a golden, custardy base that holds together beautifully when sliced.

Step-by-Step Directions: How to Make High Protein Crustless Pizza

1. Preheat the oven and prep your pan
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with avocado oil spray, olive oil, or a bit of butter.
You want a pan that’s big enough so the egg mixture isn’t too deep; this helps it cook evenly and hold that “sliceable pizza” texture.

2. Whisk together the high protein base
In a large mixing bowl, crack in the eggs. Whisk until they’re smooth and a bit frothy—this incorporates some air, which keeps the base light rather than dense.
Add the Greek yogurt and ricotta cheese, and whisk again until mostly smooth. A few tiny ricotta specks are okay, they’ll melt in the oven.

3. Add cheese and seasonings
Stir in 1 cup shredded mozzarella, ¼ cup grated Parmesan, garlic powder, onion powder, dried Italian seasoning, salt, and pepper.
This mixture should look like a well-seasoned, slightly thick egg batter—this is the heart of your low carb high protein pizza.

4. Pour and smooth the base
Pour the egg-cheese mixture into your prepared baking dish. Gently tilt the pan or use a spatula to spread it into an even layer.
If it looks uneven, just give the pan a small wiggle—nothing fancy.

5. Par-bake the base
Bake the base (without sauce or toppings yet) for 12–15 minutes, until the edges are just barely set but the center is still a little jiggly.
This step helps the high protein crustless pizza hold structure so it doesn’t get soggy once we add the sauce.

6. Add the sauce layer
Remove the dish from the oven and reduce oven temperature slightly to 350°F (175°C).
Spoon pizza sauce over the hot base and gently spread it into a thin, even layer. Leave a tiny border around the edges if you like those crispy, cheesy bits.

7. Load up with cheese and toppings
Sprinkle about 1 cup of the shredded mozzarella over the sauce.
Add your toppings: turkey pepperoni, crumbled sausage, mushrooms, onions, bell peppers, and olives. Distribute them fairly evenly to avoid heavy “wet” spots.
Finish with the remaining ½ cup mozzarella on top, then sprinkle dried oregano and red pepper flakes, if using.

8. Bake until bubbly and golden
Return the dish to the oven and bake for another 18–22 minutes, or until the cheese is melted, bubbly, and starting to turn golden brown around the edges.
You’ll know it’s ready when the center no longer looks liquid, and the edges of the high protein oven baked pizza are nice and set.

9. Rest before slicing (this matters!)
This is the hard part: let the crustless high protein pizza rest for at least 10–15 minutes before cutting.
That rest time lets the protein structure set up, so you get clean slices that behave more like pizza than scrambled eggs.

10. Slice and serve
Slice into 8–10 squares. Serve warm with a big green salad, some roasted veggies, or even a side of steamed broccoli for a healthy high protein family dinner that still feels like comfort food.

Servings & Timing

• Yield: About 8 generous slices (serves 4–6 as a main, depending on appetites)
• Prep Time: 10–15 minutes (chopping toppings, whisking base)
• Par-Bake Time: 12–15 minutes
• Final Bake Time: 18–22 minutes
• Rest Time: 10–15 minutes
• Total Time: Around 50–60 minutes from start to table

If you’re meal-prepping, you can easily double the recipe and bake it in two pans at once—this high protein meal prep pizza reheats so well.

Fun Variations: Make This Crustless Pizza Your Own

You know what? Once you have the basic formula down, the variations are half the fun. Here are a few to get you started:

• Veggie Supreme Crustless Pizza – Load it up with mushrooms, bell peppers, onions, spinach, artichokes, and black olives for a veggie-heavy, nutrient-dense twist.
• BBQ Chicken High Protein Pizza – Swap the red sauce for a light layer of sugar-free BBQ sauce, then top with shredded cooked chicken, red onion, and a sprinkle of cheddar.
• Mediterranean Crustless Pizza – Use a garlicky marinara, then add feta, kalamata olives, red onion, spinach, and a light drizzle of olive oil after baking.
• Spicy Meat Lovers Low Carb High Protein Pizza – Add extra turkey sausage, turkey pepperoni, and diced Canadian bacon, then finish with red pepper flakes and a touch more Parmesan.
• Breakfast Crustless Pizza – Use the same base, skip the pizza sauce, and top with crumbled turkey bacon, sautéed spinach, and a sprinkle of cheddar—great for brunch or “brinner.”
• Kid-Friendly Cheese & Pepperoni Version – Keep toppings simple with just sauce, mozzarella, and turkey pepperoni for picky eaters.

Storage & Reheating Tips

One thing I love about this healthy crustless pizza is how friendly it is for leftovers and meal prep.

• Fridge Storage:

  • Let the pizza cool completely, then transfer slices to an airtight container.
  • Store in the refrigerator for up to 4–5 days.

• Freezer Storage:

  • For longer storage, place cooled slices on a parchment-lined baking sheet and freeze until solid.
  • Move them into a freezer-safe bag or container; they’ll keep well for up to 2 months.
  • Label with the date—future you will be very grateful.

• Reheating (Fridge):

  • Microwave: 45–60 seconds per slice, just until hot.
  • Oven or toaster oven: 350°F (175°C) for about 8–10 minutes; this keeps the texture closer to “fresh baked.”

• Reheating (Frozen):

  • For best results, thaw slices in the fridge overnight, then reheat as above.
  • In a pinch, you can reheat from frozen in a 350°F oven for 15–20 minutes.

• Make-Ahead Advice:

  • You can assemble the high protein crustless pizza base and par-bake it up to 24 hours ahead.
  • Keep it covered in the fridge, then add sauce and toppings and bake right before serving.

Notes & Personal Tips from My Kitchen

• Don’t skip the par-bake.
  I tried skipping this step once when I was rushing between work emails and feeding the dog—big mistake. The base turned out wetter and didn’t hold up as well. That first 12–15 minutes in the oven makes a world of difference.

• Watch your sauce.
  Using a very thin or watery sauce can make this feel soggy. A thicker pizza sauce or marinara works best, especially if you’re after that firm, sliceable texture in your no crust high protein pizza.

• Balance your toppings.
  Too many “wet” veggies (like mushrooms and peppers) can release moisture. If I’m using a lot of them, I’ll quickly sauté them first in a dry pan to cook off some of the liquid.

• Don’t be scared of seasoning.
  Eggs and dairy can mute flavors. Taste your sauce first; if it’s bland, stir in a bit more garlic, Italian seasoning, or even a touch of salt before you assemble.

• Texture tweaks.
  If you like a firmer, more quiche-like high protein pizza dinner, bake it a few extra minutes until the center is fully set. For a softer, more custardy center, pull it closer to the 18-minute mark and let it rest well.

• Protein math (roughly).
  Depending on your toppings and cheese amounts, you’re looking at around 20–25 grams of protein per generous slice if you cut 8 slices—pretty solid for something that tastes like comfort food.

• Cast iron option.
  If you have a big cast iron skillet, this recipe works beautifully in it. You’ll get slightly crispier edges and a cozy, restaurant-style presentation.

FAQs About High Protein Crustless Pizza

1. Can I make this dairy-free?
You can, but it changes the texture. Use a dairy-free yogurt and dairy-free cheese, and skip the ricotta or replace it with a thick plant-based “cream cheese.” It won’t be quite as creamy, but it’s doable.

2. How do I keep my crustless pizza from getting watery?
Use a thicker sauce, don’t overload with raw watery veggies, and make sure you par-bake the base. Letting it rest after baking also helps the moisture redistribute.

3. Can I use egg whites instead of whole eggs?
Yes, but the texture will be a bit drier and less rich. You could try 4 whole eggs plus about 1½ cups liquid egg whites as a compromise for a lighter low calorie high protein pizza.

4. Is this recipe good for weight loss?
It can be—this is a high protein, relatively low carb, and fairly low calorie option compared to traditional pizza, especially if you use lean meats and plenty of veggies. Pair it with a salad and you’ve got a filling crustless pizza for weight loss.

5. Can I make this in a smaller pan?
You can use a 9×9-inch or 8×11-inch pan, but the base will be thicker, so you may need a few extra minutes of baking time. Check the center for doneness before pulling it out.

6. What if I don’t like Greek yogurt?
You don’t really taste it as “yogurt” in the final dish; it just adds protein and creaminess. But if you really dislike it, you can use more ricotta or cottage cheese instead.

7. Can I add fresh herbs?
Absolutely. Fresh basil, parsley, or even a little rosemary sprinkled on after baking adds beautiful flavor and color. Just add them after it comes out of the oven so they don’t burn.

8. Does this work as a high protein meal prep pizza for the week?
Yes, very well. Bake it on Sunday, chill, slice, and pack into containers. It reheats quickly and travels nicely for work lunches or quick dinners.
