Baked Spaghetti Recipe With Ground Beef: Cheesy Layers in One Pan

This baked spaghetti delivers restaurant-quality comfort in a single dish. The combination of tender pasta, seasoned ground beef, and melted cheese creates a meal that’s both hearty and satisfying.

What sets this apart is the layering technique—each bite contains spaghetti, beef, and gooey cheese in perfect balance. The pasta cooks directly in the sauce, absorbing flavors as it bakes, while the beef adds richness and texture.

The result is a golden-brown top with bubbling cheese edges and a filling that’s creamy without being heavy. It’s a crowd-pleaser that reheats beautifully, making it ideal for meal prep or feeding a group.

Simple to assemble, with minimal cleanup. Here’s how to make it.

Ingredients for Baked Spaghetti Recipe with Ground Beef

Restaurant-quality comfort starts with these layered pantry staples and fresh ingredients.

The ground beef is the foundation—80/20 lean-to-fat ratio gives you the best flavor and moisture without being greasy. Whole Foods or Costco carry excellent grass-fed options, but any supermarket ground chuck works. For the marinara, Rao’s or Victoria brands are professional-grade choices that elevate the dish. The cheeses should be freshly shredded (pre-shredded contains anti-caking agents that don’t melt as well).

Need to swap the beef? Ground turkey or Italian sausage work well—just adjust seasoning. No mozzarella? Provolone or Monterey Jack melt beautifully. For a lighter version, cottage cheese mixed with egg between layers adds protein without heaviness. The oregano and basil can be fresh at double the amount, finely chopped. Always taste your marinara before using—some brands need a pinch of sugar.

Assemble and bake immediately, or refrigerate the unbaked dish for up to 24 hours. Leftovers keep 4-5 days in the fridge and reheat like a dream. Freeze portions (without the top cheese layer) for up to 3 months—just thaw overnight before baking.

Step-by-Step Instructions for Baked Spaghetti With Ground Beef

This one-pan method ensures perfectly cooked pasta and a rich, layered cheese sauce.

Step 1: Brown the Ground Beef and Aromatics

Heat the 2 tbsp Olive Oil in a large, deep skillet over medium-high heat. Add the 1 lb Ground Beef, breaking it up with a wooden spoon. Cook until browned and no longer pink, about 5-7 minutes.

Add the finely diced 1 whole Yellow Onion and 3 cloves Garlic Cloves to the skillet. Sauté for 2-3 minutes until the onion softens and becomes translucent. Season with 1.5 tsp Kosher Salt, 0.5 tsp Ground Black Pepper, 1 tsp Dried Oregano, and 1 tsp Dried Basil. Stir to combine and cook for another 30 seconds to bloom the spices.

Step 2: Combine Pasta, Sauce, and Liquid

Stir the 3 cups Marinara Sauce and 1.5 cups Water into the skillet with the beef mixture, scraping up any browned bits from the bottom. This builds a rich, savory base for the pasta to cook in.

Add the uncooked 12 oz Spaghetti Noodles to the skillet, pressing them down into the liquid so they’re fully submerged. If necessary, break the noodles in half to fit. Bring the mixture to a boil, then reduce the heat to medium-low.

Step 3: Simmer Until Pasta Is Tender

Cover the skillet and let the pasta simmer for 10-12 minutes, stirring occasionally to prevent sticking. The pasta should absorb most of the liquid and become al dente. If the mixture seems dry, add a splash of water to keep it saucy.

Uncover and continue cooking for another 2-3 minutes until the sauce thickens and the spaghetti reaches your desired tenderness. The noodles should be coated in a rich, meaty sauce with minimal standing liquid.

Step 4: Layer and Bake with Cheese

Preheat the oven to 375°F. Sprinkle half of the 2 cups Shredded Mozzarella Cheese and 1 cup Shredded Cheddar Cheese over the pasta in the skillet. Stir gently to distribute the cheese throughout the dish.

Top with the remaining mozzarella and cheddar, then sprinkle the 0.5 cup Grated Parmesan Cheese evenly over the top. Transfer the skillet to the preheated oven and bake for 10-12 minutes, until the cheese is fully melted, bubbly, and beginning to turn golden brown in spots.

Step 5: Rest and Serve

Remove the skillet from the oven and let it rest for 5 minutes to allow the cheese to set slightly. This makes serving easier and ensures the layers hold together.

Use a spatula to serve generous portions directly from the skillet. Each serving should feature tender pasta, a hearty beef and sauce layer, and a gooey, cheesy topping. Garnish with additional herbs if desired.
