This easy slow cooker lasagna layers tender noodles with rich meat sauce and three cheeses, all with just 25 minutes of hands on prep. You get classic, cozy lasagna flavor that melds into every bite from slow cooking all day!
The Magic Behind The Melt
- Hands-off ease: Classic lasagna flavor with almost no active cooking. Load it, walk away, come back to dinner.
- Layers stay intact: The slow, steady cook keeps everything together! There are no sliding layers or soupy middles.
- All-day aroma: It fills your kitchen with that slow simmered, Italian-Sunday smell without the actual work of an Italian Sunday.
Slow Cooker Lasagna Ingredients
- Meat: Use half ground beef and half Italian sausage for a richer flavor.
- Cheese Swap: You can use ricotta cheese instead of cottage cheese. I just like how cottage cheese keeps after cooking for so long.
- Noodles: No-boil or regular lasagna noodles both work; either will soften with the long cook time.
- Cheese: Freshly shredded cheese melts better than pre-shredded.
- Sauce: Use about 3½ cups homemade marinara instead of jarred if you prefer.
- Mushrooms: Sautéed mushrooms add moisture and depth.
How to Make Slow Cooker Lasagna
Lasagna always feels like a labor of love. But, for some reason, when I put it together in a crockpot, it feels so much easier! And I love how perfectly tender the noodles come out! Pair it with my Olive Garden salad and garlic bread!
- Prep & Brown Meat: Spray the bowl of a slow cooker with nonstick cooking spray, then set aside. Add the ground beef to a large 12 or 14-inch skillet and cook for 7-10 minutes over medium-high heat until browned and no pink remains. Drain any grease, then add the onion and garlic to the skillet, and cook for 2 minutes.
- Add Sauce Ingredients to Skillet: Stir in the marinara sauce, tomato paste, water, Italian seasoning, salt, and pepper until combined.
- Combine Cheeses: Combine the cottage cheese, mozzarella, and parmesan in a large bowl.
- Assemble: To assemble the lasagna, layer ⅓ of the meat sauce in the bottom of the slow cooker.
- Layer Noodles: Layer about a third of the lasagna noodles on top of the meat sauce, breaking them up as needed.
- Layer Cheese, Repeat & Cook: Add a third of the cheese mixture on top of the noodles. Repeat the layers twice more, finishing with the last third of the cheese mixture on top. Cover and cook on LOW for 4-5 hours or on HIGH for 3 hours, until the noodles are fully tender. Turn the slow cooker to WARM and let the crockpot lasagna rest for 15-30 minutes before serving to make dishing it up easier. Garnish with fresh parsley.
Alyssa’s Pro Tip
Jar Trick: I like to add ½ cup of water to the empty sauce jar. Then I shake it up to get the remaining sauce and pour it into the dish.
