How to Make Slow Cooker Lasagna
To prep this easy slow cooker lasagna, you’ll start by softening some onion in a skillet on your stove. Then you’ll add your ground beef to the skillet and cook it until the meat is browned. Finally, you’ll add some minced garlic and sauté for 30 seconds to cook off the raw garlic flavor.
Once the meat is browned, it takes just a few minutes to layer the ingredients in your slow cooker. Here is how you layer the lasagna ingredients:
- Spread a little bit of marinara sauce in the bottom of your slow cooker.
- Make a layer of noodles, breaking them up as needed to make them fit.
- Add 1/3 of the meat, 1 cup of marinara sauce and some shredded mozzarella.
- Repeat the noodles, meat, tomato sauce and cheese layers two more times.
- For the top layer, you’ll use noodles, sauce and cheese.
Cook the lasagna in your slow cooker for about 4 hours, until the noodles are soft. Let the lasagna rest for 20-30 minutes before serving it to make it easier to slice.
Cooking Tips for Crockpot Lasagna
- Be sure to use your favorite marinara sauce in this crockpot lasagna since the flavor of the sauce intensifies as the lasagna slowly cooks.
- Use regular (NOT no boil) lasagna noodles, and layer the noodles uncooked in your slow cooker. I have made this slow cooker lasagna with both whole wheat and white lasagna noodles and both work well.
- You can use ground turkey in place of the ground beef. If you like sausage in your lasagna, you can add 1/2 pound of sausage and cook it with the ground beef in the skillet.
- You can add ricotta cheese to this lasagna recipe. When you layer the lasagna, spoon the ricotta on top of the noodles and spread it out a bit.
- After the cook time ends, turn off the heat and let the lasagna rest for 20-30 minutes. The rest time will make it easier to slice and serve your lasagna.
Easy Slow Cooker Lasagna
- 1 tablespoon olive oil
- 1 medium onion, chopped
- 1 pound lean ground beef, or ground turkey
- salt and pepper
- 4 cloves garlic, minced
- 2 24 ounce jars marinara sauce, about 5 1/2 cups total*
- 10 lasagna noodles, uncooked, whole wheat or white (NOT no boil noodles)
- 10 ounces mozzarella cheese, shredded, 2 1/2 cups
- grated Parmesan cheese, for serving
- fresh chopped parsley or basil, for serving, if desired
- Heat olive oil in a large skillet over medium-high heat. Add the onion and cook for 1-2 minutes, stirring, until it begins to soften.
- Add the ground beef (or turkey) to the skillet and season with salt and pepper. Cook until browned and cooked through, breaking up the meat into small pieces as it cooks.
- Add the garlic and cook for 30 seconds, stirring. Remove pan from the heat.
- Spread 1 cup of the marinara sauce in the bottom of the slow cooker insert. Make a single layer of noodles, breaking them up as needed. Top with 1/3 of the meat, 1 cup of marinara sauce, and 2/3 cup shredded mozzarella.
- Make a second layer with noodles, half of the remaining meat, another 1 cup of sauce, and 2/3 cup mozzarella.
- Make a third layer with noodles, the remaining meat, 1 cup sauce and 2/3 cup mozzarella.
- Top with one more layer of noodles, 1 ½ cups of sauce, and the remaining 1/2 cup mozzarella
- Cook in your slow cooker on low heat for about 4 hours, until noodles are soft. Turn off heat and let stand, covered, for 20-30 minutes before serving. Open lid carefully to keep any condensation on the lid from dripping on the lasagna. Serve with grated Parmesan and fresh parsley or basil, if desired.
- Use a marinara sauce that you really enjoy as the flavor of the sauce intensifies as the lasagna cooks.
- All slow cookers cook differently. This takes about 4 hours on low in my slow cooker, but yours may cook a little faster or slower.
