How to Make the Best Baked Spaghetti

This baked spaghetti has everything we love about baked pasta. There’s noodles, a hearty meat sauce, lots of cheese, and we even add a layer of sour cream mixed with basil pesto to the middle.

My favorite thing about baked spaghetti is that it comes together quickly. We love pasta and red sauce, but we love it even more after adding sweet cooked onions and ground beef. You can use homemade marinara sauce — here’s our version — or use jarred spaghetti sauce.

How to Make the Best Baked Spaghetti

To make the meat sauce, cook onions and ground beef until the beef is browned. (We’ve made this recipe with ground chicken and ground turkey before, both are excellent). Add the marinara sauce, bring it to a simmer, and then toss with cooked spaghetti.

Here’s a tip: Undercook the spaghetti by 1 to 2 minutes. This way, when we toss it with the marinara sauce and bake, the pasta won’t become mushy.

Toss spaghetti with marinara sauce

You can add the spaghetti and meat sauce to a baking dish and top with cheese, but to make this the best baked spaghetti, add a creamy pesto layer to the middle.

To make it, mix sour cream with basil pesto. Add half of the spaghetti and sauce to a baking dish then spread the creamy pesto on top. Finish by adding the remaining pasta on top.

To finish, add lots of mozzarella cheese to the top and bake until bubbly.

This easy baked spaghetti has ground beef, marinara sauce, and a middle layer of creamy pesto. If you are like us, this will become your new favorite meal! Consider swapping the ground beef for sausage, ground chicken or ground turkey. To make this meatless, remove the beef – the spaghetti will still be delicious. You could also add some cooked vegetables like mushrooms and zucchini.

Makes approximately 8 servings

You Will Need

1 pound pasta, such as spaghetti or linguini

1 tablespoon olive oil

1 medium onion, chopped

1 pound lean ground beef

6 cups marinara sauce, see our homemade marinara sauce recipe (or substitute with two 26-ounce jars store-bought sauce)

3/4 cup sour cream

1/4 cup basil pesto, see our homemade basil pesto recipe

4 ounces mozzarella cheese, coarsely grated (about 1 cup)

Salt and fresh ground black pepper

Directions

  • Prepare Pasta
  • Heat oven to 350 degrees F. Butter a 3-quart baking dish or spray with non-stick cooking spray.

    Bring a large pot of salted water to the boil, add the pasta then follow package directions, but cook 1 to 2 minutes less than the package calls for. Drain.

    Meanwhile, heat the olive oil in a large skillet with sides. Add onions and cook until translucent, about 5 minutes. Add the ground beef and cook until browned, about 10 minutes. As the beef cooks, use a wooden spoon to break the beef up into small pieces in the pan. Season with 1/4 teaspoon of salt and a few grinds of black pepper. Drain excess fat from the beef.

    Pour in the marinara sauce and cook until heated through. Take the pan off of the heat and add the cooked and drained pasta. Toss well then taste for seasoning and adjust with salt and black pepper. In a small bowl, stir sour cream and basil pesto together until well blended.

    • To Finish
    • Spoon half of the pasta into the baking dish. Spread the sour cream and pesto mixture over the pasta and scatter with half of the mozzarella cheese. Top with the remaining pasta, lightly press everything down into the baking dish and then scatter spread remaining mozzarella cheese on top.

      Place the baking dish onto an aluminum-lined baking dish (just in case any sauce drips over the sides of the baking dish). Bake until the cheese has melted and the sauce is bubbling; about 30 minutes. Let stand about 10 minutes before serving.

Adam and Joanne's Tips

  • If making ahead, you can cover and refrigerate, unbaked up to 2 days. When you cover, use parchment or wax paper between the spaghetti and aluminum foil. Aluminum foil can react with the tomatoes.
  • The meat sauce can be made in advance and should last in your refrigerator up to 3 days and in your freezer for about three months. We recommend using freezer-safe glass containers, or double layers of freezer bags to store sauces. To thaw, leave it overnight in the refrigerator.
  • Baked spaghetti also freezes well. Let it cool completely on a rack before freezing, and then wrap it very well with foil (we use two layers). Defrost the frozen spaghetti overnight in the refrigerator and then bake at 350 degrees F for about 1 hour.

    I made this recipe , divided into 2 pans to take to two families who are recovering from illness. I was intimidated at first, because both are excellent cooks and both women born Italians. Both called me later to tell me sincerely how much they enjoyed it. One husband asked for me to share the recipe! The reason I chose this one was because of the pesto, sour cream mixture in the center. the only addition I made was some freshly shredded parmesean on top of each mozzarella layer. Thank you for this recipe. I dont usually take something to others before trying it myself. so glad I trusted my instincts. This is definately a KEEPER!!! As my Italian friends would say, Bravo!!!
