When making lasagna, you'll pre-cook the sheets of pasta along with any meat you're using in the recipe. Make sure not to overcook the pasta — you'll want it to be just shy of al dente. Once you've pre-cooked these ingredients and layered them with the sauce, cheese and whatever else your heart desires, baking simply serves to heat the food and blend flavors (rather than cook the dish to a safe level of doneness).

The baking time and temperature needed for lasagna is approximately the same no matter what the recipe's ingredients are — for example, you can add meat, spinach, mushrooms or béchamel. That being said, cooking time can vary depending on the size and material of the pan in which you're baking the lasagna and how many layers your lasagna has.

If you use a 13" x 9" glass baking dish, and your lasagna has at least three layers, it will take approximately 45 minutes to cook in an oven set to 375 degrees Fahrenheit.

We've provided our go-to basic meat lasagna recipe and baking method below, along with healthy-ish lasagna recipes plus tips on the best way to freeze and reheat your lasagna — because when it comes to make-ahead dishes that you can eat all week, lasagna is king.

Bake lasagna at 350 to 375 degrees Fahrenheit. The optimal amount of time to bake lasagna depends on what baking dish you're cooking it in. As a rule, wait until the sauce bubbles over the top layer of pasta and cheese.

Recipe for Oven-Baked Lasagna


  • 2 tablespoons olive oil
  • 1 pound sweet Italian sausage
  • 15-ounce jar tomato sauce (we recommend buying Rao's brand, or making your own)
  • 3/4-1 lb lean ground beef
  • salt and pepper
  • 18 lasagna noodles
  • 16 ounces ricotta cheese
  • 1 egg
  • 1 pound mozzarella cheese sliced
  • 1 cup grated Parmesan cheese


Step 1: Heat 2 tablespoons olive oil in a sautee pan over medium heat. Add ground beef and sausage to the pan, season liberally and cook until well browned. Drain off the excess fat from the pan, then add in your jar of tomato sauce.

Step 2: Bring a pot of salted water to a boil. Cook lasagna noodles for about 8 minutes or until al dente. Drain pasta, toss with a bit of olive oil and set aside.

Step 3: Combine the ricotta with the egg in a mixing bowl.

Step 4: Preheat your oven to 375 degrees Fahrenheit. Allow about 30 minutes of preheating time to ensure that your oven reaches the correct temperature. (Adjust an oven rack so that the lasagna will be situated in the middle of your oven. This improves heat circulation and ensures that your lasagna bakes evenly.)

Step 5: To assemble, start by spreading 1/3 of the meat sauce in the bottom of a 13" x 9" baking dish. Top with 6 pieces of the cooked pasta, 1/3 of the ricotta mixture, 1/3 of the mozzarella slices and 1/3 of the grated parmesan. Repeat layers in this order (for a total of three layers), ending with the parmesan on top.

Step 6: Cover the 13" x 9" baking dish with foil and bake the lasagna for approximately 30 minutes or until a visual inspection shows the sauce bubbling over the top layer of pasta and cheese. Covering the pan prevents the lasagna's top layer from browning too quickly while the middle is still cooking.

Step 7: Remove the foil and bake the lasagna for another 10 minutes to brown the top of your lasagna. After you pull the lasagna out of the oven, let it stand for approximately 10 minutes before serving.

After you pull the lasagna out of the oven, let it stand for a bit — approximately 10 minutes — before serving.
