Kitchen Equipment

You’ll need the following kitchen tools:

Large stockpot
Colander
Large skillet
Wooden spoon
Mixing bowl
9×13-inch baking dish
Measuring cups
Cheese grater (if using block cheese)

Step-by-Step Instructions

Step 1: Prepare the Pasta

Fill a large pot with water and bring it to a rolling boil.

Add a generous pinch of salt to the water before adding the macaroni.

Cook the pasta according to the package directions until it reaches an al dente texture. The pasta should still have a slight bite because it will continue cooking in the oven.

Drain the pasta well and set it aside.

Step 2: Brown the Ground Beef

While the pasta cooks, heat a large skillet over medium heat.

Add the ground beef and cook for about 7 to 10 minutes, breaking it apart with a wooden spoon until no pink remains.

Drain off any excess grease.

If desired, season the beef lightly with salt, black pepper, garlic powder, and Italian seasoning for extra flavor.

Step 3: Mix Everything Together

Preheat your oven to 375°F (190°C).

In a large mixing bowl, combine:

Cooked macaroni
Browned ground beef
Pasta sauce

Mix thoroughly until every piece of pasta is coated in the rich tomato sauce.

Stir in half of the shredded mozzarella cheese.

This creates a creamy, cheesy filling throughout the casserole.

Step 4: Assemble the Casserole

Lightly grease a 9×13-inch baking dish.

Pour the pasta mixture into the baking dish and spread it into an even layer.

Sprinkle the remaining mozzarella cheese evenly across the top.

For an extra cheesy finish, you can add a little grated Parmesan.

Step 5: Bake

Bake uncovered for 20 to 25 minutes.

The casserole is ready when the cheese has completely melted, becomes bubbly, and starts turning lightly golden around the edges.

Remove from the oven and let it rest for about 5 to 10 minutes before serving.

Allowing the casserole to rest helps it hold together better when sliced.

Serving Suggestions

This comforting pasta casserole pairs perfectly with many side dishes.

Some delicious serving ideas include:

Garlic bread
Fresh garden salad
Caesar salad
Roasted broccoli
Steamed green beans
Buttered dinner rolls
Roasted carrots
Garlic roasted Brussels sprouts
Homemade coleslaw

For larger family dinners, serve it alongside roasted chicken or grilled vegetables.

Tips for the Best Johnny Marzetti

Choose a high-quality pasta sauce since it’s one of the main ingredients and greatly affects the final flavor.

Cook the pasta just until al dente to prevent it from becoming too soft after baking.

Freshly shredded mozzarella melts much better than pre-shredded cheese.

Allow the casserole to cool for several minutes before serving for cleaner portions.

Use lean ground beef to reduce excess grease.

If you enjoy extra cheesy casseroles, sprinkle additional mozzarella over the top during the final five minutes of baking.

Easy Recipe Variations

Cheesy Johnny Marzetti

Mix in cheddar, Monterey Jack, or provolone cheese for an even richer flavor.

Spicy Version

Add crushed red pepper flakes or diced jalapeños for a little heat.

Meat Lover’s Version

Replace half of the ground beef with Italian sausage for a heartier casserole.

Vegetable Version

Mix in cooked mushrooms, onions, bell peppers, spinach, zucchini, or diced tomatoes for added nutrition.

Creamy Version

Stir in half a cup of sour cream, cream cheese, or ricotta cheese before baking for an extra creamy texture.

Storage Instructions

Store any leftovers in an airtight container in the refrigerator for up to 4 days.

The flavors often become even better the next day as the ingredients continue to blend together.

Freezing Instructions

This casserole freezes exceptionally well.

To freeze before baking:

Assemble the casserole as directed.
Cover tightly with plastic wrap followed by aluminum foil.
Freeze for up to 3 months.

To bake from frozen, thaw overnight in the refrigerator and bake according to the recipe instructions.
