Ingredients You’ll Need

Ingredients You’ll Need
One of the best things about the Meatzza Casserole Recipe is how streamlined it is—just a handful of staple ingredients that, when combined, create distinctive layers of taste and texture. Each component plays a vital role, from the robust base of seasoned meats to the final cheesy topping.
- Ground beef: Provides a hearty, flavorful base and classic meaty richness essential for that satisfying “meat crust.”
- Italian sausage (casings removed): Brings in robust, herby spice and juicy texture that blends beautifully with beef.
- Small onion (diced): Adds gentle sweetness and depth, softening as it cooks into the mix.
- Garlic (minced): A couple of cloves give a savory, aromatic kick that brings the casserole together.
- Italian seasoning: A ready-made blend of herbs like oregano and basil amps up the classic pizza vibes.
- Salt, black pepper & crushed red pepper flakes (optional): Controls seasoning and lets you adjust the heat to your preference.
- Marinara sauce: This tangy tomato layer ties everything together—use your favorite brand or homemade for an extra-special touch.
- Grated Parmesan cheese: Adds a salty, nutty bite that works wonders as a layer beneath the mozzarella.
- Shredded mozzarella cheese: The magic ingredient that turns bubbly, golden, and gloriously gooey in the oven.
- Chopped fresh basil or parsley (optional for garnish): A sprinkle of green gives a fresh flavor burst and an inviting finish.
- Olive oil for greasing: Keeps everything from sticking and adds a little richness underneath it all.
How to Make Meatzza Casserole Recipe
Step 1: Prep the Oven and Baking Dish
Start by preheating your oven to 375°F (190°C)—this ensures it’s hot enough for the cheese to melt perfectly while the flavors meld. Lightly grease a 9×13-inch baking dish with olive oil so your casserole slides out easily and develops just a hint of a crispy edge.
Step 2: Brown the Meats
In a large skillet over medium heat, add the ground beef and Italian sausage. Break the meat apart as it cooks, letting the fat render and edges start to caramelize. Take your time here; this step lays the flavor foundation that makes the Meatzza Casserole Recipe so irresistible.
Step 3: Sauté the Aromatics
Once the meats are nicely browned, toss in the diced onion and minced garlic. Sauté everything together for about 3–4 minutes; you’ll smell when the onions are soft and the garlic becomes fragrant. This layer adds a subtle, savory sweetness that balances out all the richness.
Step 4: Season to Perfection
Stir in the Italian seasoning, salt, black pepper, and a pinch of red pepper flakes if you love a gentle heat. Taste as you go, adjusting the spice level so each bite is perfectly seasoned but never overwhelming.
Step 5: Drain and Layer
Remove the skillet from heat and carefully drain most of the excess fat (a little left behind is fine for flavor). Spread the meat mixture evenly over the bottom of your prepared baking dish, making an even layer for maximum enjoyment in every spoonful.
Step 6: Sauce and Cheese
Pour the marinara sauce evenly across the top of your meat base, spreading it with the back of a spoon. Sprinkle on the grated Parmesan for that sharp, salty bite, followed by an avalanche of shredded mozzarella that will melt into gooey perfection in the oven.
Step 7: Bake to Golden, Bubbling Glory
Bake uncovered for 20–25 minutes until the cheese is deeply melted, the edges start to bubble, and the top just brushes golden brown. Let the Meatzza Casserole Recipe rest for 5 minutes before cutting—this helps everything set, so you lift out perfect squares every time.

Garnishes
A generous sprinkle of chopped fresh basil or parsley just before serving adds a burst of color and brings garden-fresh brightness to the finished dish. For a little extra flair, you could even add a few sliced olives or roasted red peppers to echo your favorite pizza toppings.
Side Dishes
This casserole shines as a centerpiece, but it’s even better with sides that play off its hearty nature. Try crispy roasted vegetables, a vibrant mixed greens salad, or even simple steamed broccoli.

Make Ahead and Storage
Storing Leftovers
Leftovers keep well for up to four days in an airtight container in the fridge. This casserole tastes just as fabulous reheated, and the flavors meld even more as it rests. If planning ahead, portion it out for easy meal prep lunches or dinners throughout the week.
Freezing
Cool the casserole completely before wrapping tightly in foil and freezing for up to three months. For best results, slice into portions and freeze individually—this way, you can pull out just what you need any night of the week. Thaw overnight in the fridge before reheating.
Reheating
Reheat individual portions in the microwave, covered loosely with a damp paper towel to retain moisture, or warm the entire casserole in a 325°F oven covered with foil until heated through. A quick broil at the end revives that irresistible cheesy top layer.
