There are weeks when pizza night feels non-negotiable in my house — and honestly, I never argue with it. But after years of making traditional pies with my Aunt Anne, I started wondering if we could get all that melty, saucy, pepperoni-loaded satisfaction without the dough holding us back. That’s how this Protein Crustless Pizza Pie was born — and it hasn’t left our dinner rotation since. It comes together in one baking dish , packs serious protein from mozzarella, cottage cheese, and eggs, and delivers every bit of that comforting pizza flavor we all crave. If you love pizza cottage cheese bake style dinners, this one takes it even further with a custardy, golden-set filling that holds every slice perfectly. I’ve served it at family dinners and weeknight tables alike — and it disappears every time. If you’re ready for a hearty, nourishing dinner the whole family will celebrate, let’s make it.

Ingredient Notes
- Marinara sauce — Use a good-quality sauce; it’s the flavor backbone of the entire pie.
- Shredded mozzarella cheese — Freshly shredded melts more evenly and gives a stretchier, golden top.
- Cottage cheese — Adds creaminess and a protein boost; it blends invisibly into the filling.
- Large eggs — The structural base that sets the pie and holds every slice together cleanly.
- Dried oregano — Brings that classic Italian herb note; rub it between your fingers before adding.
- Garlic powder — Deepens the savory flavor without overpowering; don’t skip it. I also love it paired with cottage cheese flatbread nights.
- Fresh basil — Most goes into the egg mixture for flavor throughout; reserve a little to scatter fresh on top after baking.
- Pepperoni or preferred toppings — Lay them on top so they crisp up beautifully while baking.

How to Make Protein Crustless Pizza Pie?
- Preheat oven — Heat to 375°F (190°C) and lightly grease a 9-inch baking dish or pie pan.
- Mix the egg base — Whisk together eggs, cottage cheese, garlic powder, dried oregano, and all but 2 tbsp of the fresh basil until fully combined.
- Layer the marinara — Pour marinara sauce evenly across the bottom of the greased baking dish .
- Add the first cheese layer — Sprinkle 1 cup of the shredded mozzarella over the marinara in an even layer.
- Pour the egg mixture — Slowly pour the egg and cottage cheese mixture over the cheese layer.
- Top with remaining mozzarella — Scatter the remaining 1 cup of mozzarella evenly over the egg mixture.
- Place the toppings — Arrange pepperoni slices or your preferred toppings across the surface.
- Bake until set — Bake for 35 minutes until the center is firm and the top is golden and bubbling.
- Rest before slicing — Let the pie sit for 5–10 minutes before cutting for clean, firm slices.
- Garnish and serve — Scatter the reserved 2 tbsp of fresh basil over the top and serve warm.

Emily’s Expert Tips
- Don’t skip the rest. Cutting into the pie straight from the oven will cause it to fall apart — those 5–10 minutes let the egg filling finish setting so every slice holds its shape. I’ve learned this the hard way more than once.
- Drain excess moisture if needed. If your marinara is on the thinner side, let it sit in a strainer for a few minutes before adding it to the dish — this prevents a watery base. Aunt Anne always reminded me that a good bake starts with dry layers.
- Customize the toppings freely. Mushrooms, olives, bell pepper strips, or cooked sausage all work beautifully here — just make sure any raw vegetables are pre-sautéed so they don’t release extra water into the bake.
Storage Tips
- Refrigerate — Store in an airtight container for up to four days.
- Reheat — Warm individual slices in a 350°F oven for 8–10 minutes for best texture.
- Freeze — Wrap slices tightly and freeze for up to two months; thaw overnight before reheating.
- Avoid microwave reheating — It softens the top; the oven keeps the mozzarella nicely melted.
Variations & Substitutions
- Swap pepperoni for Italian sausage — Brown it first and drain before adding to the top. Try it alongside meat pizza casserole flavors for a hearty spin.
- Use ricotta instead of cottage cheese — Gives a slightly richer, creamier filling with a smoother texture.
- Go vegetarian — Load with sautéed mushrooms, spinach, and roasted red peppers instead.
- Add red pepper flakes — Stir into the egg mixture for a subtle, warming heat throughout.
- Try a white sauce base — Swap marinara for garlic cream sauce for a completely different flavor profile — inspired by garlic toast pizzas nights.

What to Serve With Protein Crustless Pizza Pie?
- A crisp arugula salad — The peppery bitterness cuts right through the rich, cheesy pie.
- Garlic roasted broccoli — A hearty, nourishing side that rounds out the meal perfectly.
- A light cucumber and tomato salad — Refreshing and bright alongside the savory bake.
- Sparkling water with lemon — Cleanses the palate between each satisfying slice.
Frequently Asked Questions
Can I make this ahead of time? Yes — assemble the night before, refrigerate unbaked, and bake fresh the next day.
How do I know when it’s done baking? The center should be firm, not jiggly, and the top golden and bubbling.
Can I use egg whites only? Yes — substitute 8 egg whites for the 4 whole eggs for an even leaner version.
Is this recipe gluten-free? Yes, as written — just verify your marinara and toppings are certified gluten-free.
Can I freeze the whole pie? I’d slice it first, wrap each piece individually, and freeze for up to two months.
What size baking dish works best? A 9-inch round pie dish or an 8×8 square pan both work perfectly.

Protein Crustless Pizza Pie
Ingredients
Instructions
Preheat oven to 375°F (190°C) and lightly grease a 9-inch baking dish or pie pan.
In a large bowl, whisk together eggs, cottage cheese, garlic powder, dried oregano, and all but 2 tbsp of the fresh basil until fully combined.
Pour marinara sauce evenly across the bottom of the greased baking dish.
Sprinkle 1 cup of shredded mozzarella over the marinara in an even layer.
Slowly pour the egg and cottage cheese mixture over the cheese layer.
Scatter the remaining 1 cup of mozzarella evenly over the egg mixture.

Remove from oven and let the pie rest for 5–10 minutes before slicing for clean, firm pieces.
Scatter the reserved 2 tbsp of fresh basil over the top and serve warm.
Notes
Do not skip the resting time — cutting too soon will cause the filling to fall apart; 5–10 minutes off heat lets it fully set.
If your marinara is thin or watery, strain it for a few minutes before adding to prevent a soggy base.
Pre-sauté any raw vegetables (mushrooms, peppers, spinach) before adding as toppings to avoid excess moisture in the bake.
Ricotta can replace cottage cheese for a richer, creamier filling with a smoother texture.
Store leftovers in an airtight container in the fridge for up to 4 days; reheat slices in a 350°F oven for 8–10 minutes for best texture.
To freeze, wrap individual slices tightly and store for up to 2 months; thaw overnight in the fridge before reheating.
