No! This is why I love this recipe so much. You don’t even have to boil the noodles! Get the comfort food flavour of lasagna that your family loves without spending hours in the kitchen. You just put the hard noodles in and as it bakes they will tenderize like regular pasta!
John adores lasagna and always asks me to make it. I rarely make it the traditional way anymore. It’s so time-consuming and there are many other ways to get the same lasagna taste without the extra work. This recipe isn’t my first lasagna hack. I’ve shared a Lasagna Tater Tot Casserole, Lasagna Bowl and Lasagna Soup previously.

This is a meatless recipe to save on time. However, you could include some ground beef, chicken or turkey if you like. Just cook it in a skillet first before adding it your sauce.
It’s slow cooker season so why not try a new recipe. If you enjoy comfort food, you’ll most likely love this recipe. And I know you’ll love how easy it is to make.
How Long Does it Take to Cook Lasagna in the Slow Cooker
For my slow cooker lasagna recipe it took around 3 hours and 15 minutes to cook. The key is ensuring your pasta is tender and fully cooked. When your pasta is cooked your lasagna is ready to slice up and serve your family or guests.
What to Serve With Lasagna
- Garlic Bread
- Roasted or Steamed Broccoli
- Green Beans
- Crisp Green Salad
- Or any other side dish you enjoy!
Can I Add Meat to this Slow Cooker Lasagna Recipe
Of course. Cook up and ground your beef, sausage or turkey and mix it into the sauce mixture or create its own layer of just meat as you create your layers.
Now, adding meat will change how much fits into the slow cooker. So if you have extra noodles leftover just save them back for another meal later down the line.

*Be sure to use regular lasagna noodles. NOT the ‘no boil’ noodles.
**After the 3 hour cook time, it is fine to leave the lasagna ‘warming’ throughout the day. If your slow cooker has an auto shut off, then you can use that too.
If you would like to add meat to this recipe, just cook ground beef/turkey prior to adding lasagna to slow cooker. Then add meat into layers of lasagna. You might have extra lasagna noodles after assembling – that is fine, just use what you need and save rest for another time.
