Why make lasagna in the slow cooker?

It’s really as simple as knowing that choosing your favorite pasta sauce will let you make an amazing dinner that will be done with very little effort. Is it a cheater kind of meal? Sure. In fact, it may not be so much a recipe as a meal idea. But I also know that many of you are like me and it pains you to spend a money eating out only because you didn’t have time to make dinner. Having simple go-to items on hand (in this case only 3!!) makes this a dish that can serve as a backup on a busy day or even a yummy treat when everyone wants lasagna. They don’t have to know it was easy to make this 3 Ingredient Slow Cooker Lasagna!

Notes for making this slow cooker lasagna recipe:

  • Use no boil noodles, a carton of ricotta and your favorite sauce for layers and layers of cheesy goodness.
  • I love a tomato basil sauce and the fresh flavor works really well in this simple dish.
  • I layered this up in my casserole crock which cooks lasagna perfectly for me every time.
  • This takes about 15 minutes of prep time and will cook in about 2-3 hours on high or 4-6 on low
  • Plan your time because you don’t want this sitting for too long after cooking as the noodles can get overdone

If you don’t have a casserole slow cooker, I’ve also done lasagna in my oval slow cookers and it works very well, you just have to break up the noodles to fit. Either way, get these few ingredients and make yourself a meal that will be better, easier and so much cheaper than takeout!!

Can you really make pasta dishes in the slow cooker?

Yes!! Some of my most popular recipes on this site are pasta recipes in the slow cooker! And this cheese lasagna is probably the easiest because we use no boil noodles that will cook up perfectly. They come in both flat and regular ridged so you can choose what works best for you. Other favorite pasta recipe are buffalo chicken pasta and chicken alfredo pasta.

Can I add/change/adjust this recipe?

This is a very basic recipe and delicious on it’s own. It’s perfect for kids and picky eaters alike, but would also be easy to customize for your family. Some ideas include:

  • brown ground beef and season with Italian seasoning and add to layers
  • swap ricotta for cottage cheese, mozzarella cheese or Italian cheese blend
  • add leftover shredded chicken
  • add layers of Alfredo sauce
  • add fresh herbs

If you make this, leave a comment and let me know if you make it as is or if you customize it!

  1. You can also use regular lasagna noodles instead of the no-bake ones as the sauce and the length of time in the crockpot will soften up the noodles nicely.
