Why This Recipe Works
This casserole replicates traditional pizza with minimal effort. The eggs and cheese create a self-binging, moist interior while the toppings add textures and visuals that mimic standard pizza. It’s oven-ready in 45 minutes and requires only one pan for clean-up.
I’ve tested multiple cheeses to find the best combination of melt and flavor. Mozzarella provides gooeyness while Parmesan adds depth without overpowering the marinara. The meat and veggie layering creates a satisfying bite that remains low in carbs.

Step-by-Step Instructions
Preparation
- Preheat oven to 350°F (175°C). Grease a 9-inch square baking dish with olive oil spray.
- In skillet, cook ground beef over medium heat until browned (8-10 minutes) breaking into small pieces. Drain excess fat.
- Add bell peppers and onions to skillet; sauté for 3-5 minutes until slightly softened.
- In large bowl, combine cooked beef mixture, pepperoni, marinara sauce, mozzarella, Parmesan, eggs, Italian seasoning, salt, and pepper.
- Pour mixture into prepared baking dish, spreading evenly into corners.
Cooking
- Bake for 25-30 minutes or until top is golden and edges are firm.
- Remove from oven and let rest for 10 minutes before slicing.
- Cut into squares and serve warm.
Chef Tips for Perfect Results
- Simmer marinara first: Reduces water content by 30-40% preventing a soggy texture
- Press mixture firmly: Fill dish to 3/4 capacity to prevent overflow during baking
- Use fresh cheese: Old cheese crumbles and creates gaps in the texture
- Don’t overcook onions: Maintain slight crunch for better contrast in final bites
- Grease dish thoroughly: Cooking spray plus butter ensures no sticking after resting period
Common Mistakes to Avoid
- Using watery mozzarella: Creates liquid pockets – always use low-moisture cheese
- Skipping marinara simmer: Excess liquid makes casserole runny; better to reduce thickness first
- Mixing wet and dry ingredients too long:过度搅拌会导致鸡蛋液体分离; stir gently after adding cheese
- Baking without preheating: Results in uneven cooking and rubbery texture
- Cutting too soon
