For busy oven days or busy days in general, this Slow Cooker Three Meat Lasagna will take the stress out of meal preparation. After preparing the rich meat sauce and assembling the rest is up to my personal chef, aka slow cooker. The slow cooker simmers the rich and meaty marinara sauce with uncooked lasagna noodles to tender perfection. Layers of seasoned ricotta cheese, slices of spicy pepperoni and lots of gooey cheese complete the ensemble. It will make you think you’re dining at an Italian restaurant instead of at your own kitchen table.
Slow cookers, much like ovens, can vary wildly in temperature depending on their shape and age. FDA guidelines have changed throughout the years and so has the crockpot manufacturing industry. So, consider those factors when you’re making any slow cooked dish be it from my website or others. Just know, next time you plan a family-pleasing feast, the layers of Italian love in this lasagna will delight your hungry eaters. Mangia!

September 18, 2017 at 8:50 amThis looks fantastic. I’ve been wanting to try the “slow cook” function on my Instant Pot and this will be just the recipe I’ll try it with.
Thanks for the great post!

January 26, 2018 at 9:32 amDo you use regular lasagna noodles or no boil? Would either work? Thank you! I can’t wait to try this!
Melissa says
January 26, 2018 at 12:38 pmEither will work. I used regular.

February 5, 2018 at 8:37 pmIs that a typo or is does the recipe really call for 67 oz marinara sauce?
Melissa says
February 6, 2018 at 8:15 amThat’s not a typo. The equivalent of 3 (20-oz) jars.
Michelle Colbaugh says
February 22, 2018 at 11:26 pmI believe step #4 had a typo, where it says “…cook string…” Instead of ‘stiring’. 😊
Melissa says
February 23, 2018 at 7:45 amGot it Michelle. (No strings allowed lol)

March 18, 2018 at 3:22 pmCan you cook this on high, and if so, for how long?
Melissa says
March 19, 2018 at 4:04 pmYou can. Typically cooking on high takes half the amount of time but, test it as slow cookers are just like ovens, and can vary wildly.

September 8, 2018 at 4:59 pmI don’t like sausage in my pasta. I know to add extra beef, but are there any other changes I should make?
Melissa says
September 8, 2018 at 5:00 pmNone at all, you can adapt it without any other changes.
Donna says
October 23, 2018 at 11:34 pmThat’s what I used. If you go by directions it turns out amazing!! I wouldn’t change a thing.
I will be taking this to church tomorrow for our potluck…can’t wait.
The sausage adds that little zip to the sauce and blends nicely. It doesn’t stand out. Worth adding it.

November 20, 2018 at 2:43 amMost of the crockpot recipes ive found water is added why didnt you add water to yours
Melissa says
November 20, 2018 at 7:30 amBecause there’s ample sauce in this recipe water isn’t necessary.
