Equipment You’ll Need

• Large pot for boiling the pasta
• Large skillet for browning the ground beef
• 9×13 inch glass baking dish
• Glass Pyrex measuring cup
• Wooden spoon
• Colander for draining

Ingredients

• 1 lb lean ground beef
• 12 oz curly pasta (like cavatappi or egg noodles)
• 1 can (15 oz) diced tomatoes, undrained
• 1 can (15 oz) tomato sauce
• 2 cups shredded mozzarella cheese
• 1 cup shredded sharp cheddar cheese
• 1 medium yellow onion, diced
• 3 cloves garlic, minced
• 1 tbsp olive oil
• Fresh chopped parsley or basil for garnish
• Seasonings: 1 tsp Italian seasoning, salt, and black pepper

Ingredient Substitutions

If you prefer a leaner option, ground turkey works wonderfully in place of the ground beef. You can swap the curly pasta for penne, macaroni, or even rotini. If you want a bit of a kick, use a can of diced tomatoes with green chilies instead of plain tomatoes!

How to Make It

1. Boil the Pasta

Bring a large pot of salted water to a rolling boil. Cook your curly pasta for about 1 to 2 minutes less than the package instructions so it remains al dente. Drain well and set aside.

2. Brown the Beef and Onions

Heat the olive oil in a large skillet over medium-high heat. Add the diced yellow onion and ground beef, breaking the meat apart with a wooden spoon. Cook until the beef is fully browned and the onions are soft.

3. Add Aromatics and Tomatoes

Drain any excess grease from the skillet. Stir in the minced garlic and cook for just one minute until fragrant. Pour in the diced tomatoes, tomato sauce, Italian seasoning, salt, and black pepper, stirring to combine.

4. Combine Pasta and Sauce

Turn the heat to low and let the meat sauce simmer for 5 minutes. Gently fold the cooked curly pasta directly into the skillet, ensuring every noodle is coated in the rich, savory beef mixture.

5. Layer and Bake

Pour the entire pasta and beef mixture into your 9×13 inch glass baking dish, spreading it out into an even, messy layer. Top generously with the shredded mozzarella and sharp cheddar cheese. Bake uncovered at 350°F for 20 minutes.

6. Garnish and Serve

Bake until the cheese is bubbling, gooey, and perfectly golden brown around the edges. Let the casserole rest for 5 minutes, then garnish with fresh torn parsley or basil before digging in!

Variations

• Stir a cup of sour cream into the pasta mixture before baking for a creamier texture.
• Add diced bell peppers or sliced mushrooms while browning the onions.
• Use a mix of provolone and Monterey Jack cheese for a different flavor profile.
• Top with crispy fried onions during the last 5 minutes of baking for a satisfying crunch.

What to Serve With

This beef casserole is incredibly filling on its own, so I love pairing it with fresh, simple sides. A crisp garden salad with a tangy vinaigrette cuts through the richness beautifully. At Golden Recipes, we also highly recommend serving it with warm, buttery garlic knots!

Pro Tips

• Undercook your pasta slightly; it will finish cooking while baking in the tomato sauce.
• Always shred your own cheese from a block for the meltiest, gooey topping.
• Let the casserole rest for a few minutes after baking so the sauce thickens and sets.
• Don’t drain the diced tomatoes! The juices add essential moisture and flavor to the dish.
• Use a glass baking dish so you can see those beautiful, bubbling edges.

Common Mistakes

• Overcooking the pasta in the boiling water, resulting in a mushy casserole.
• Forgetting to drain the excess grease from the ground beef before adding the sauce.
• Using pre-shredded cheese, which contains anti-caking agents that prevent a smooth melt.
• Baking at too high of a temperature, causing the cheese to burn before the center is hot.
• Skipping the fresh herb garnish; it adds a much-needed pop of brightness.

Storage and Reheating

Store any leftover casserole in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave, or cover the whole baking dish with foil and warm in a 350°F oven until hot and bubbly.
