Ingredients
- 1 pound lean ground beef
- 1 small onion, diced
- 3 garlic cloves, minced
- 2 cups elbow macaroni
- 1 (24-ounce) jar marinara sauce
- 1 (15-ounce) can tomato sauce
- 1 teaspoon Italian seasoning
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon smoked paprika
- Salt and black pepper to taste
- 2 cups shredded mozzarella cheese
- 1 cup shredded sharp cheddar cheese
- ¼ cup grated Parmesan cheese
- Fresh parsley for garnish (optional)
How to Make Oven Baked Johnny Marzetti
Start by preheating your oven to 375°F. Grease a 9×13-inch baking dish and set it aside.
Cook the elbow macaroni in salted boiling water until just al dente. Drain well.
Meanwhile, brown the ground beef with the diced onion in a large skillet over medium-high heat. Once the beef is cooked through, drain any excess grease. Stir in the minced garlic and cook for about 30 seconds until fragrant.
Next, add the marinara sauce, tomato sauce, Italian seasoning, garlic powder, onion powder, smoked paprika, salt, and pepper. Stir everything together and let the sauce simmer for about five minutes.
Add the cooked macaroni to the meat sauce and mix until every piece of pasta is coated.
Spread half of the pasta mixture into the prepared baking dish. Sprinkle half of the mozzarella and cheddar cheese over the top. Add the remaining pasta mixture and finish with the rest of the mozzarella, cheddar, and Parmesan cheese.
Bake uncovered for 25 to 30 minutes, or until the cheese is melted, bubbly, and lightly golden. Let the casserole rest for about 10 minutes before serving.
Tips for the Best Johnny Marzetti
Cook the pasta just until al dente. It will continue cooking in the oven, so slightly firm pasta keeps the casserole from becoming too soft.
Freshly shredded cheese melts much better than pre-shredded cheese. If you have a few extra minutes, shredding your own cheese makes a noticeable difference.
If you like extra flavor, add sliced mushrooms, diced bell peppers, or a handful of spinach to the meat mixture. You can also stir in crushed red pepper flakes for a little kick.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to four days.
To reheat, microwave individual servings until hot or warm the casserole in a 350°F oven for about 20 minutes. Add a little extra mozzarella before reheating if you want another layer of melted cheese.
This casserole also freezes well. Wrap it tightly and freeze for up to three months. Thaw overnight in the refrigerator before baking or reheating.
What to Serve with Oven Baked Johnny Marzetti
This hearty pasta bake pairs perfectly with garlic bread, warm dinner rolls, or a crisp green salad. Steamed broccoli, roasted green beans, or buttered corn also make excellent side dishes. If you’re serving guests, finish the meal with brownies, chocolate cake, or a scoop of vanilla ice cream.

Whether you’re cooking for your family, preparing meals ahead of time, or bringing a dish to share with friends, this casserole always gets rave reviews.
