What Is Johnny Marzetti?

Johnny Marzetti is a classic American baked pasta casserole traditionally made with noodles, ground beef, tomato sauce, and cheese. The dish is associated with the Marzetti restaurant in Columbus, Ohio, and became especially popular as an easy family-style meal.

There are many variations today, with some recipes adding onions, mushrooms, peppers, or additional seasonings. This simplified version focuses on four essential ingredients while keeping the casserole hearty and flavorful.

Ingredients

For this easy 4-ingredient version, you’ll need:

8 ounces elbow macaroni – Cooked until just tender so the pasta holds its texture during baking.
1 pound ground beef – Provides the savory, hearty base for the casserole.
24 ounces tomato-based pasta sauce – Brings moisture and rich tomato flavor to the dish.
2 cups shredded mozzarella cheese – Creates the golden, bubbly cheese topping.

You’ll also need water and a little salt for cooking the pasta. These are cooking necessities rather than part of the four main ingredients.

How to Make 4-Ingredient Johnny Marzetti

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Add the elbow macaroni and cook according to the package directions.

For the best baked casserole, avoid cooking the pasta until it becomes very soft. Drain it when it is just tender, since it will continue cooking in the oven.

Set the drained pasta aside while you prepare the beef.
