This Slow Cooker Lasagna recipe is perfect for feeding a crowd with just a little prep! In only 3 hours on high or 6 hours on low, you can have a beautifully layered lasagna with lasagna noodles, a beef/Italian sausage sauce, and three types of cheese. Perfect for Sunday Supper!
How to Make Slow Cooker Lasagna
The Slow Cooker Lasagna is created by layering uncooked lasagna noodles with a meat sauce and three types of cheese. I used a large oval slow cooker to give myself plenty of room for assembly. Arranging the noodles in a circular slow cooker will be more difficult.
The layers can be cooked on high in the slow cooker for 3-4 hours or low for 6-8 hours. Once done, allow the lasagna to cool (I know this will be difficult!) for 15-20 minutes. The lasagna slices tend to fall apart if you try to dig in earlier, so resting lasagna is a must!

Do you have to cook the meat before adding to the slow cooker?
Yes. The meat needs to be cooked on the stove-top before layering with the noodles and cheese in the slow cooker. However, save time the day of assembly by cooking the meat the night before and refrigerate until needed. Be sure to drain any fat that may have accumulated in the pan before adding the marinara sauce and water.
I use a combination of ground beef and crumbled mild Italian sausage for personal taste, but you can also use purely ground beef or even ground turkey for a lighter option.
How much salt and pepper you add to the meat sauce will depend on how much is in the marinara sauce. Adjust the seasonings as needed. If desired, add 1/2 teaspoon or so of crushed red pepper flakes to the meat as it browns for a little heat. Some dried oregano would also add a boost of flavor.
What types of cheese are best in lasagna?
This slow cooker lasagna uses three types of cheese! Among the layers are a lightly seasoned ricotta mixed with freshly chopped parsley, shredded mozzarella, and grated Parmesan. Be sure to set aside a little mozzarella and Parmesan for the topping. Once the lasagna has finished slow cooking, I like to top it with the remaining mozzarella/Parmesan, cover, and cook for another 10 minutes in the slow cooker to allow the mozzarella to melt.
How do you layer the lasagna?
The most time-consuming part of this Slow Cooker Lasagna is the layering. The most important part is to start with 2 cups of the meat sauce. This will prevent the bottom from burning and help cook the noodles. Cover the sauce with a layer of UNCOOKED lasagna noodles, breaking them as needed to get them to cover the whole area. Top with 1/3rd of the ricotta, followed by a sprinkling of mozzarella and Parmesan. Repeat this sequence two more times. Top the last layer of ricotta/mozzarella/Parmesan with a layer of lasagna noodles and finally 1 1/2 cups of the meat sauce.
Here is a cheat sheet for easy reference:
- 2 cups sauce
- Lasagna noodles
- 1/3rd Ricotta cheese
- Mozzarella and Parmesan
- Sauce
- Lasagna noodles
- 1/3rd Ricotta cheese
- Mozzarella and Parmesan
- Sauce
- Lasagna noodles
- 1/3rd Ricotta
- Mozzarella and Parmesan
- Lasagna noodles
- 1 1/2 cup Sauce
Immediately before serving, I topped the melted cheese with a sprinkling of fresh parsley, but basil would also be perfect when in season.
