Williams Sonoma Slow Cooker Lasagna

Sharing is caring!

A super thick and cheesy Lasagna made in the crock pot makes a hearty family meal with a minimum amount of effort. This is one of the easiest lasagna recipes ever and it is the only lasagna I ever cook in the crock pot. Slow Cooker Lasagna is so perfect, as much as I love to try new recipes, I can’t bring myself to try another slow cooker lasagna.

This Williams Sonoma Slow Cooker Lasagna rocks!

In fact, I think it may be my favorite lasagna period.

You probably don’t believe that lasagna cooked in a crock pot can be better than one baked in the oven. I was completely skeptical too.

Two pounds of Italian sausage and plenty of gooey cheese make this a lasagna to be reckoned with. Just 4 hours in the crock pot, plus a quick broil to melt the cheese is all it takes. You do have to brown the sausage beforehand, but it only takes a few minutes.

A store bought spaghetti sauce really saves time, but you’ll never be able to tell a homemade sauce wasn’t used.

And there is no need to cook the noodles first. Win!

Be sure to use regular noodles, NOT no-boil.

This tasty Italian meal is a cinch to make for even the most novice cook. Pair it with a salad and bread and you easily have enough food to cover dinner for 2 nights.

Print Recipe


  • 1/2 Tablespoon olive oil
  • 2 lbs Italian Sausage, casings removed
  • 2 24-ounce jars spaghetti sauce
  • 2 cups water
  • 1 15- ounce container whole-milk ricotta cheese
  • 2 tablespoons chopped parsley
  • salt and ground pepper to taste
  • 16 lasagna noodles, NOT no-boil
  • 1 1/2 lbs shredded mozzarella, or however much you have in the bottom of your cheese drawer
  • 1/2 cup shredded or grated Parmesan Cheese


  • In a large skillet, heat olive oil over medium heat. Cook sausage, breaking into pieces, until browned (10-12 minutes).
  • Add spaghetti sauce and water, bring to simmer and turn heat off.
  • In smallish bowl, stir together ricotta, parsley, and salt and pepper.
  • Spread a layer of sauce in bottom of slow cooker insert. Cover with a layer of noodles (about 4) breaking them to fit and overlapping somewhat. Spread 1/3 of ricotta mixture on top. (Don’t worry too much about spreading the ricotta now, it will spread better when you add sauce). Spread 2 cups of sauce on top of ricotta. Sprinkle with about 1 cup mozzarella and 1/3 of Parmesan. Repeat layers 3 more times starting with noodles and finishing with a nice amount of mozzarella.
  • Cook on low in slow cooker for 4 hours.
  • Place slow cooker insert in oven and broil until cheese is bubbly and starting to brown. Let rest for 20 minutes and serve.

  1. Made this and followed it to the T. The whole bottom layer was burnt!!!
    I enjoy things on the saucier side.. this was thick and no sauce at all. All cheese and meat.
    Thanks but going to keep searching for the perfect crock pot lasagna

  2. This was not a quick prep recipe. Cooking all that meat took forever, then you have to simmer the sauce, then layer the lasagna. And my husband wanted to save a buck so I had to shred all that cheese myself. Too much prep for this preggo lady. However, if it tastes as good as it looks, I will be freezing some of it for after the baby comes, so that might make it all worth it.

  3. OH man I was just on Tastespotting to submit a pic, and saw this, and HAD to pay a visit. I’m dying over this recipe…. and the pictures… omg! Pinned, Yummed… and everything else. I’m not going to let myself forget to try this one!

  4. I’ve been on the lookout for slow cooker recipes since I work such long hours. This one would be perfect for a weekend though since it doesn’t take too long to cook…it looks awesome. I love a good cheesy lasagna 🙂

  5. This looks amazaing! Another way of making lasagna. Slow cooker instead of baked. Nevertheless, I believe it’s delicious and flavorful. And the cheese is just awesome.

  6. I love finding any reason to use my slow cooker, it’s always great to have dinner ready when you get home. This lasagna looks so incredible! My husband would totally love this 🙂

  7. I LOVE the idea of lasagna in the crockpot! I made lasagna just the other day, but I was so boring and just baked it. Next time I’m definitely pulling out the crockpot to make this cheesy, meaty perfection! Gorgeous photos too, Christin! Lasagna is definitely a challenge to photograph, but these are stunning!
