Timeless Baked Spaghetti

Timeless baked spaghetti is a casserole where pasta, meat sauce, and cheese bake together until bubbly and golden. The pasta finishes cooking in the oven, absorbing sauce and getting tender without overcooking on the stovetop first. This method keeps the noodles from turning mushy and means less stirring at the stove.

Ingredients for Timeless Baked Spaghetti

Spaghetti is cooked until just barely tender, then finished in the oven where it soaks up sauce and becomes silky. Ground beef makes the sauce meaty and rich, while onion and garlic add depth. Crushed tomatoes form the body of the sauce, and tomato paste deepens the tomato flavor. Beef broth loosens the sauce so it distributes evenly through the pasta. Olive oil helps brown the meat and carries flavor. Salt, black pepper, dried oregano, and dried basil season the sauce. Ricotta cheese adds creaminess, mozzarella cheese melts and stretches across the top, and Parmesan cheese brings a sharp, salty finish.

Why This Timeless Baked Spaghetti Works

Cooking the spaghetti only until it bends easily but still feels firm to the bite is the key. The pasta will continue to soften in the oven as it absorbs sauce and heat, so stopping short of fully tender prevents it from turning into mush by the time the cheese browns on top.

The sauce needs enough liquid to coat every strand of pasta and keep it moist during baking. Beef broth mixed with the tomatoes gives you control over how much sauce you have, so the noodles don’t dry out or become gluey and stiff.

Ricotta stirred into the sauce makes it creamy and helps it cling to the pasta. The mozzarella on top melts and browns, while Parmesan adds sharpness that cuts through the richness of the cheese and meat.

Mistakes To Avoid

Cooking the spaghetti all the way to tender on the stovetop before mixing it into the casserole will make it turn to mush in the oven. The pasta keeps cooking as it bakes, so you need to start with noodles that still have a slight firmness in the center. By the time the cheese bubbles, fully cooked pasta will have fallen apart.

Making the sauce too thick means the pasta will dry out during baking and clump together instead of staying separate and saucy. The sauce should look looser than what you would serve over plain spaghetti, because the oven evaporates some liquid as the casserole cooks.

Skipping the ricotta and using only mozzarella on top makes the casserole heavy and one-note. Ricotta mixed into the sauce keeps it light and creamy throughout, while the mozzarella on top gets brown and bubbly. The Parmesan adds a sharp edge that keeps the whole dish from tasting flat.

Baking the casserole uncovered the whole time will dry out the top layer of pasta before the inside is hot. Cover it with foil for the first 25 minutes so steam keeps the noodles tender, then uncover it to let the cheese brown in the last 15 to 20 minutes.

Ingredients

• 1 pound ground beef
• 1 medium onion, diced
• 3 cloves garlic, minced
• 2 tablespoons olive oil
• 1 can (28 ounces) crushed tomatoes
• 3 tablespoons tomato paste
• 1 cup beef broth
• 1 teaspoon salt, plus more for pasta water
• 1/2 teaspoon black pepper
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• 1 pound spaghetti
• 15 ounces ricotta cheese
• 2 cups mozzarella cheese, shredded
• 1/2 cup Parmesan cheese, grated

Step-by-step Instructions

1. Heat 2 tablespoons olive oil in a large skillet over medium-high heat. Add 1 pound ground beef and cook for 5 to 7 minutes, breaking it into small pieces with a spoon, until no pink remains and the meat is browned. Drain off excess fat if needed.
2. Add diced onion to the beef and cook for 3 minutes, stirring often, until the onion softens and turns translucent. Add minced garlic and cook for 1 minute more, until fragrant.
3. Stir in 3 tablespoons tomato paste and cook for 1 minute, letting it darken slightly and stick to the bottom of the pan. Pour in 1 can crushed tomatoes and 1 cup beef broth, scraping up any browned bits from the bottom.
4. Add 1 teaspoon salt, 1/2 teaspoon black pepper, 1 teaspoon dried oregano, and 1 teaspoon dried basil. Stir well and bring to a gentle simmer. Simmer uncovered for 10 minutes, stirring occasionally, until the sauce thickens slightly.
5. While the sauce simmers, bring a large pot of salted water to a boil. Add 1 pound spaghetti and cook for 1 to 2 minutes less than the package directions suggest, until the pasta bends easily but still feels slightly firm in the center. Reserve 1 cup of pasta cooking water, then drain the pasta.
6. Remove the sauce from heat and stir in 15 ounces ricotta cheese until smooth. Taste and add more salt or pepper if needed. If the sauce looks too thick, stir in a few tablespoons of reserved pasta water.
7. Preheat the oven to 375°F (190°C). Pour half the sauce into a 9×13 baking pan. Add the drained spaghetti and pour the remaining sauce over it. Stir gently to coat the pasta evenly.
8. Sprinkle 2 cups shredded mozzarella cheese over the pasta, then sprinkle 1/2 cup grated Parmesan cheese on top. Cover the pan tightly with aluminum foil.
9. Bake covered for 25 minutes. Remove the foil and bake for 15 to 20 minutes more, until the cheese is melted and bubbling at the edges and the top is lightly golden. The center should be hot all the way through when you insert an instant-read thermometer into the middle of the casserole.
10. Remove the pan from the oven and let it rest for 5 minutes. The casserole will set slightly and become easier to serve.
