Ingredients
Makes one 9×13-inch casserole (6–8 servings)
- 1 lb ground halal-friendly turkey or beef
- 2 cups shredded mozzarella cheese
- 8 oz cream cheese, softened
- 1 cup ricotta or cottage cheese (see pairing ideas below)
- 1/2 cup grated Parmesan
- 1 large egg
- 1 cup low-sugar pizza sauce
- 1 cup diced bell peppers (mix of red and yellow for color)
- 1/2 cup sliced mushrooms
- 1/2 cup sliced black olives (optional)
- 1/2 cup sliced turkey pepperoni
- 1 tsp Italian seasoning
- 1/2 tsp garlic powder
- Salt and pepper to taste
- Fresh basil or parsley for garnish
If you enjoy cottage-cheese-forward recipes, this casserole pairs wonderfully with the textures in a cottage cheese pizza bowl recipe for variations on the same flavors.
Step-by-step instructions
- Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
- Brown the meat: In a large skillet over medium heat, cook the ground turkey or beef until no longer pink. Season with salt, pepper, garlic powder, and half the Italian seasoning. Drain any excess fat.
- Prepare the cheese mixture: In a bowl, beat the cream cheese until smooth. Stir in ricotta (or cottage cheese), Parmesan, egg, and 1 cup of mozzarella until combined. Add a pinch of salt and the remaining Italian seasoning.
- Layer the casserole: Spread half of the meat mixture in the bottom of the prepared dish. Spoon half of the cheese mixture over the meat and spread gently. Add a layer of diced peppers, mushrooms, olives, and turkey pepperoni. Pour half of the pizza sauce evenly over the toppings. Repeat the layers (meat, cheese mixture, veggies, sauce).
- Top and bake: Sprinkle the remaining 1 cup mozzarella over the top. Cover loosely with foil and bake for 20 minutes. Remove foil and bake an additional 10–15 minutes until bubbly and golden on top. Let rest 10 minutes before serving. Garnish with fresh basil.

Tips for success
- Don’t over-moisturize the cheese layer: Drain cottage cheese or ricotta in a fine sieve if it seems watery so the casserole sets nicely.
- Evenly distribute toppings so each slice gets a balanced bite of sauce, cheese, and veggies.
- If using fresh mushrooms, sauté them briefly to remove excess moisture.
- Let it rest after baking to firm up — this makes slicing much cleaner.
- For crusty edges, broil the top for 1–2 minutes at the end, watching closely to prevent burning.
If you’re looking for gluten-free crust alternatives or store-bought options to mimic a pizza base in other recipes, you may find ideas at a resource about gluten-free pizza options like California Pizza Kitchen gluten-free choices useful when adapting sides.
Possible variations
- Gluten-free: This casserole is naturally low-carb and can be served with roasted cauliflower slices or a thin almond-flour flatbread for a fuller meal. For a cottage-cheese twist, pair with a simple bowl variation inspired by the cottage cheese pizza bowl.
- Streusel-style topping: For a savory streusel, pulse 1/2 cup almond flour with 2 tbsp melted butter, 1/4 cup grated Parmesan, and a pinch of oregano. Sprinkle over the casserole before the final bake for a golden, crunchy finish.
- Vegetarian: Swap meat for a mix of diced eggplant, zucchini, and extra mushrooms, and add a tablespoon of tomato paste to deepen flavor.
- Spicy: Add red pepper flakes to the sauce or use spicy turkey pepperoni for a flavor kick.
Storage recommendations
- Refrigerator: Store leftovers in an airtight container for up to 4 days. Reheat individual servings in the microwave for 1–2 minutes or in a 350°F oven covered with foil for 10–12 minutes.
- Freezer: Cool completely, then wrap tightly and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating. Reheat from frozen at 350°F covered for 30–40 minutes, then uncover until bubbly.
