This Crockpot Lasagna is one of those recipes that I didn’t actually expect to be as good as I hoped it would be, and we were blown away by the results!

With just 6 ingredients (what?!) and a few hours in the slow cooker, it is the perfect weeknight meal or Sunday dinner.

I wasn’t sure how lasagna noodles would do in the slow cooker for several hours.

Normally when I make pasta in the crockpot (like this Crockpot Chicken and Noodles or this Crock Pot Mac and Cheese), I add the pasta just for the last 15 or 20 minutes so they are not overcooked.

But since lasagna noodles are larger and they are stacked, this recipe comes together perfectly in just 3 or 4 hours — no mushy noodles, just big flavor.

And, yes, I’ve stuck with the basics because this Lasagna is part of my Six Ingredient Suppers series, but I’ve included tons of additions and ways to make it your own down below.

But it is incredibly delicious and comforting just the way it is 😉

Variations and substitutions for Crockpot Lasagna:

If you’ve been around here before, you know I believe in making things your own and try to include helpful tips on ways to make most recipes just the way you like them.

Obviously, I haven’t tested all of these substitutions but I do cook all day, every day so I’ve learned a thing or two 😉

Can I swap out the Italian sausage?

The Italian sausage is responsible for a lot of the flavor in this Crockpot Lasagna, since I kept it to 6 ingredients.

You can substitute the Italian sausage for turkey sausage (for a lighter recipe), or ground beef, chicken or turkey.

If you opt for unseasoned ground meat, you will want to add additional seasoning when you are browning it.

Can I use oven ready lasagna noodles?

I haven’t tested this recipe with oven ready noodles, so I can’t make any promises.

My best guess is that it would work fine, but you may want to check the lasagna for doneness a little sooner.

Can I add ricotta, cottage cheese or beschamel?

Absolutely!

I make my classic Easy Lasagna Recipe with a layer of Ricotta cheese, but I know many others love cottage cheese or beschamel.

However you love to make your regular oven baked lasagna, you can do the same here.

Simply whip up your favorite addition (see my Easy Lasagna Recipe above for a ricotta mixture recipe), and spread it in the layers as you normally would.

Can I add extra vegetables?

Definitely!

There are lots of ways to add extra vegetables here.

Feel free to stir some shredded or finely chopped vegetables into the sausage as it browns, or stir in some chopped spinach just before layering.

Tips for making the best Slow Cooker Lasagna:

  • Lightly grease your crockpot: we don’t want any of that deliciousness to stick!
  • Cook on low: I really try to avoid using my crockpot on high unless I have to. Because the outer edges will already cook more quickly on low, I avoid using high because it may cause your edges to burn before the inside is cooked through.
  • Don’t stress over perfect layers: you will have to break your noodles to fit, and it won’t be perfect. Don’t worry! It’s okay if they overlap a bit, or they don’t cover completely. As the noodles cook, they will expand and cover and mishaps 😉
  • Broil, if you want to: I know there are a lot of you out there who love a good crispy browned cheese crust. Most slow cooker crocks are oven safe, so you can broil the cheese for a few minutes before serving if desired (but be sure to check first!).

    Hi,

    I made this recipe, and it was delicious! I’m looking for a low base crockpot. Where did you find the crockpot shown here?

    • The Recipe Rebel says

      I’m sure you could, but I’ve not tested the recipe with zucchini so I wouldn’t be able to advise on specifics on what to do.

  2. Delia says

    I tried the Tuscan chicken, it was my first time. I don’t really like cooking, but I’ll be trying the slow cooker lasagna meal today. I’ll be cooking for my mom and I. I really enjoy your recipes, it’s not too complicated, and it was fun! 🤩

  3. Gayle Ann says

    Forgot to mention, when I make the filling, I double it in my KitchenAid, and actually use the second bowl to make another double batch. Put into ziploc bags, pressing flat, and freeze. Let at least partially defrost, and then break it into 2 pieces, once for each layer. Makes making it the second time so much easier.

    • Gayle Ann says

      I make a filling of 1 carton of ricotta cheese, 2T parsley, and an egg, for each batch. I also use hamburger, and precook it with some garlic and minced onion.

      I’ve given the prepped ingredients to people in need of a meal, and it works well because if they have been given several, it all goes into the freezer, minus the jar of Prego meat sauce, until they need it. Pasta, baggie of cooked meat, bag of filling, bag of shredded mozzarella for the top. I find I use about 2/3 of one of the LARGE plastic jars. Some recipes call for adding water for the pasta. I prefer adding extra sauce.

      My layers:

      sauce
      pasta
      sauce
      cheese and meat filling
      sauce
      pasta
      sauce
      cheese and meat filling
      sauce
      pasta

      Put more sauce on top of the fresh pasta sheet, than under it.

  4. Gayle Ann says

    I make this, and I use the fresh pasta sheets from the grocery store. I like them better than hard noodles. They fit perfectly, and no breaking the noodles to fit. I also get an extra layer… pasta, filling, pasta, filling, pasta, so it looks more like “regular” lasagna.

    I also find Prego works best. It is a stronger flavor, and the others I tried, Berolli comes to mind first, were so bland that it was tasteless. Also, don’t overcook, as it changes the sauce flavor and not for the better.

  5. Susan says

    I made this tonight exactly as written and it was so,so good….first time for me to make lasagna but this will definitely be my go to recipe…
    Thank you for such a easy and good recipe…

  6. TL says

    Going to make this for supper tonight. I’ve just poured water into my crock pot to figure out how big it is 🤣 it’s not quite at the rim and it’s holding 5 quartz …. It’s bigger than what you use – how should I adjust ingredients/cook time?

    • The Recipe Rebel says

      Hi TL, I’m not sure you would have to adjust the time too much. I would just start checking the noodles at the timing given in the directions and go from there. Hope you enjoy it!

  7. Aubrey says

    I tried this and unfortunately it burned to a crisp. I left for work around 6:30 am on low set to cook for 3 hours. It was set to keep it warm until I got home from work, but it was very burnt when I returned. What did I do wrong?

    • The Recipe Rebel says

      Hi Aubrey, I’m sorry to hear that happened. This cooks in only 2 1/2-3 hours so it sounds like it was overcooked.

  8. Sierra says

    Could you double this recipe? I have a family of 5 and this barely gave us all a bowl when I made it. They LOVE it and it makes busy nights so easy.

  9. Hannah Jones says

    Tried it after reading the recipe. My family enjoyed it so much as they want it again the next day. This is also a good food to bring for potlucks and family lunches, thank you so much for sharing this awesome recipe!

  10. Theresa H. says

    My crockpot has its settings by hours not by low/medium/ high. Should I put it on the 8 or 10 he program and then just time it myself for 2.5 or 3 hours? Thoughts?

    • Ashley Fehr says

      Hi Theresa! That is strange. I don’t think I’ve ever seen a crockpot that doesn’t have a temperature setting. I would just choose 8 hours and then set another timer for 2.5-3 hours.

  11. Robin Dierksen says

    Made this for dinner tonight and my husband and I both really enjoyed it. Easiest lasagna I have ever made. It is going on my dinner rotation.

  12. Kathy Rowland says

    I usually do the grocery store freezer lasagna, but this looks fun, easy, and delicious. Will give it a try! Kathy at quiethollow.com
