High Protein Ground Beef Pizza Casserole – Easy Low Carb Dinner Recipe

High-protein | Low-carb | Family-friendly dinner

Ingredients

• 1 lb lean ground beef
• 8 oz sliced pepperoni
• 8 oz cream cheese, softened at room temperature
• 2 cups shredded mozzarella cheese
• 1 cup low-sugar pizza sauce
• 1 cup chopped bell peppers (any color you like)
• Optional: 1/4 cup sliced black olives
• Optional: 1 teaspoon Italian seasoning
• Optional: chopped mushrooms or fresh spinach

Instructions

1. Set the oven to 375°F (190°C) and lightly coat a 9×13-inch baking dish with cooking spray or oil.
2. Place the ground beef in a large skillet and cook over medium heat, breaking it up as it browns. Once fully cooked, transfer it to a colander lined with paper towels to remove excess grease.
3. Put the drained beef back into the skillet (with the heat turned off). Add the softened cream cheese and pizza sauce, stirring until everything is well blended and creamy.
4. Spoon the beef mixture into the prepared baking dish and spread it out evenly to form the base layer.
5. Scatter the diced bell peppers across the top. Sprinkle the shredded mozzarella over the vegetables, then arrange the pepperoni slices on top. Add olives, Italian seasoning, mushrooms, or spinach if using.
6. Bake the casserole uncovered for 20–25 minutes, or until the cheese has melted and the dish is hot and bubbling around the edges.
7. For a lightly crisp, golden surface, switch the oven to broil for about 2 minutes at the end of baking.
8. Allow the casserole to rest for about 5 minutes before cutting into portions and serving.

Notes

• For softer peppers, quickly sauté them in a skillet before adding them to the casserole.
• Placing a layer of mozzarella beneath the pepperoni can create extra-gooey cheese with crispy edges.
• This dish is perfect for meal prep—divide into containers or small loaf pans and store in the refrigerator or freezer.
• Reheat leftovers in the microwave, toaster oven, or air fryer until warmed through.
