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!).

    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.

  2. 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.

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