How Long Does Lasagna Take to Cook

Lasagna is a great dish, but it can be a headache if you’re unsure how to cook it. And like any recipe around, knowing how long to let it cook is imperative. Of course, such wisdom is the difference between an exceptional meal experience and a culinary disaster. So, as you read about the proper cooking time for this Italian recipe, also take the liberty to double-check your knowledge of its cooking procedures.

Lasagna Cooking Steps

Traditional lasagna recipes are made in the oven, but other methods for cooking this delicious meal are also available. But regardless of the method, lasagna recipe directions remain the same.

Preparing the Sauce

As is typical for classic Italian dishes, lasagna sauce comprises tomato sauce base, ground beef, and chopped vegetables. More than one tomato ingredient is combined to make the base, like crushed tomatoes, tomato paste, and tomato sauce. And common vegetables used in the lasagna sauce include onions, bell pepper, shallots, garlic, parsley, celery sticks, and many others.

The ground beef is first cooked until browns, and then the vegetables are cooked separately. Then, the two ingredients are merged with the tomato sauce mix, after which seasoning and other ingredients are added to taste. And when the sauce is done, it’s set aside to wait for the noodles.

Preparing the Noodles      

For the best results, lasagna noodles need to be cooked to al dente. And the duration is subjective for this to the instructions on the package. But the water must be first salted and boiled before the noodles are added and remain boiling through the softening duration.

Selecting the Cheese

The cheese adds a creamy blend of sweetness, nuttiness and savory, and helps the noodles retain shape after baking by acting as a binder between the strips. You can use any soft cheese option in lasagna, and popular choices include mozzarella, ricotta, Parmesan, and cottage cheese.

Assembling the Ingredients

Most recipes insist upon three layers, but some have been known to get away with four. And every suggestion comprises the same pattern; sauce first, then noodles, then cheese covering, and again until the ingredients are used up.

Lasagna Cooking Time

The duration for lasagna to cook depends on your method. And we’ll be looking at the different approaches for the recipe below;

Oven: 45 minutes to one hour at 375F

Crockpot: four to six hours on LOW

Instant Pot: 25 minutes at high pressure, plus 15 minutes natural release

Both the crockpot and instant pot methods use oven-ready noodles for their recipes. And while you can cook the noodles directly in a crockpot, you’ll need a springform pan to assemble the lasagna for instant pot.

Lasagna (8 Servings)

Save Recipe


  • Half pound dry lasagna noodles, unbroken
  • One-and-a-half pound mozzarella cheese, grated
  • One pound ricotta cheese
  • Quarter pound Parmesan cheese, grated

Tomato Sauce

  • One pound ground beef chuck
  • Tomato sauce, one 24oz can
  • Crushed tomatoes, one 14oz can
  • Tomato paste, half a 6oz can
  • Quarter cup freshly chopped parsley.
  • One tablespoon white wine vinegar
  • One tablespoon Italian seasoning
  • One tablespoon sugar
  • Two teaspoons olive oil, extra-virgin
  • Two teaspoons dried oregano
  • Two garlic cloves, minced
  • Half onion, medium, diced
  • Half bell pepper, diced
  • A pinch of garlic powder
  • Salt


  1. Place a pot and add a tablespoon of salt for every two quarts of water for the pasta. Then, turn on the stove and heat while making the sauce.
  2. Cook the oil in a skillet on medium-high for two minutes, then add the ground beef and cook until it browns. Remove the cooked beef and drain excess fat.
  3. In the same pan, cook the onions and bell peppers for four to five minutes, then the minced garlic for 30 more minutes. Then, combine the beef in the pan, reduce heat to low, and cook for five more minutes.
  4. Pour the ground beef mixture into a saucepan and add the tomato ingredients. Stir the mixture and add the oregano, Italian seasoning, and parsley. Stir some more and adjust the taste with garlic powder and salt- be careful with the salt, as Parmesan is also salty.
  5. Add the vinegar, and then add sugar to preference. Then, heat the sauce to a simmer, lower heat and cook for 15 to 45 minutes, occasionally stirring and scraping the bottom, so it doesn’t burn. And once it’s ready, turn off the stove.
  6. Put the noodles in the boiling water, stirring as the water roll-boils, so they don’t stick. Continue until the noodles cook to al dente, then drain them and rinse with cold water. Separate the noodles so they won’t stick, sprinkling olive oil on their surfaces for the same purpose.
  7. Prep the oven to 375F and bring a casserole dish. Spread a cup of the sauce in the dish, followed by a layer of noodles. Spread one-third of the remaining sauce on the lasagna, followed by one-third of the mozzarella cheese. Add half the ricotta in dollops at specific spacings, then half the Parmesan cheese.
  8. Add a second layer of noodles, then half the sauce, half the mozzarella, the remaining ricotta, and remaining Parmesan cheese. Complete the lasagna assembly with a final layer of noodles, the remaining sauce, and mozzarella cheese.
  9. Cover the dish with foil, ensuring it doesn’t touch or rest on the lasagna mixture. Then, bake for 45 minutes, removing the foil cover at the final 10 minutes for a crispy top. Finally, let the lasagna cool for 15 minutes before serving.
