Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 25 minutes
• Total Time: 45 minutes
• Servings: 8
• Yield: 1 casserole
• Dietary Type: Varies (see variations for Gluten-Free, Dairy-Free)

Ingredients

• 1 lb ground beef
• 2 tablespoons chopped garlic
• 1 large onion, chopped
• 1 green bell pepper, chopped
• 3 tablespoons parmesan cheese (plus 1/2 cup grated, see below)
• Seasoning salt (can use table salt) to taste
• Pepper to taste
• 2 cups favorite pizza sauce
• 1/4 lb pepperoni, chopped (can use more)
• 1/2 – 1 teaspoon Italian herb seasoning
• 1 cup canned mushrooms, drained
• 1 cup milk
• 1 tablespoon oil
• 2 eggs
• 1 cup flour
• 1/4 teaspoon salt
• 1 pinch cayenne pepper
• 3 cups grated mozzarella cheese
• 1/2 cup grated parmesan cheese
• 8 slices cooked bacon, chopped

Equipment Needed

• 13 x 9-inch baking dish
• Large skillet
• Mixing bowl
• Electric mixer (optional, can whisk by hand)

Instructions

1. Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius).
2. Grease a 13 x 9-inch baking dish thoroughly with cooking spray or oil to prevent sticking.
3. In a large skillet over medium-high heat, cook the ground beef with the chopped onion, garlic, and green bell pepper. Break up the meat with a spoon as it cooks. Continue until the ground beef is no longer pink and the vegetables are softened, about 7-10 minutes.
4. Drain any excess fat from the skillet. This is crucial for preventing a greasy casserole.
5. Stir in 3 tablespoons of grated Parmesan cheese into the ground beef mixture. This adds a savory depth to the meat sauce.
6. Add the pizza sauce, chopped pepperoni, Italian herb seasoning, and drained mushrooms to the skillet.
7. Mix well to combine all ingredients.
8. Bring the sauce to a simmer over medium-low heat and cook for 15 minutes, stirring occasionally. This allows the flavors to meld together beautifully.
9. While the meat sauce is simmering, prepare the batter. In a separate mixing bowl, combine the milk, oil, and eggs.
10. Beat the mixture for 2 minutes with an electric mixer (or whisk vigorously by hand) until well combined and slightly frothy.
11. Stir in the flour, salt, and cayenne pepper.
12. Mix until just combined. Be careful not to overmix the batter, as this can result in a tough crust. Set aside.
13. Spoon the ground beef mixture evenly into the prepared baking dish.
14. Sprinkle the 3 cups of grated mozzarella cheese generously over the meat sauce.
15. Sprinkle the chopped cooked bacon over the mozzarella. This adds a delightful smoky crunch.
16. Pour the batter evenly over the cheese and bacon, spreading it to cover the entire surface of the casserole. A spatula can be helpful for this step.
17. Sprinkle the remaining 1/2 cup of grated Parmesan cheese over the batter. This will create a golden-brown, flavorful crust.
18. At this point, the casserole can be covered and refrigerated for later baking. This is a great way to prep ahead for busy weeknights.
19. Bake in the preheated oven for 20-25 minutes, or until the crust is golden brown and the cheese is melted and bubbly. A toothpick inserted into the center of the crust should come out clean.
20. Let cool for a few minutes before serving. This allows the casserole to set slightly and makes it easier to slice.

Expert Tips & Tricks

• Browning the Ground Beef: Don’t overcrowd the skillet when browning the ground beef. Cook it in batches if necessary to ensure it gets a good sear, which enhances the flavor.
• Cheese Placement: Layering the mozzarella under the batter helps prevent the crust from becoming soggy.
• Spice Level: Adjust the amount of cayenne pepper to your liking. A pinch adds a subtle warmth, but you can increase it for a spicier kick. Consider adding a dash of red pepper flakes to the meat sauce for extra heat.
• Preventing a Soggy Crust: Ensure the meat mixture is not overly watery after cooking. Drain any excess liquid thoroughly. You can also add a tablespoon of cornstarch to the meat sauce to help thicken it.
• Refrigerating Before Baking: If refrigerating the casserole before baking, add a few minutes to the baking time to ensure it’s heated through.
• Using Mozzarella Slices: As the original recipe note suggests, feel free to use mozzarella slices instead of shredded. Layer them evenly over the meat mixture.

Serving & Storage Suggestions

Serve the Ground Beef Pepperoni Pizza Casserole warm, straight from the oven. It’s delicious on its own, but you can also pair it with a simple side salad or garlic bread.

• Room Temperature: Do not leave the casserole at room temperature for more than 2 hours.
• Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 3-4 days.
• Freezing: For longer storage, freeze the casserole in an airtight container for up to 2-3 months. Thaw it in the refrigerator overnight before reheating.
• Reheating: Reheat individual portions in the microwave or bake the entire casserole in a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius) until heated through.
