The Slow Cooker Lasagna That Practically Makes Itself

Using your crockpot/slow cooker is without a doubt the easiest way to make lasagna! You don't even need to pre-cook the noodles! Regular lasagna noodles cook right in the slow cooker as everything simmers together. Just layer them in (break the noodles to fit, as needed) and they turn out perfectly tender every time. I love a good classic homemade lasagna, but when I'm in a time crunch or don't want to turn on the oven, this crockpot lasagna saves me every time!

I whip up a quick homemade pasta sauce using canned tomatoes, since it's way less expensive (and tastes better) than a jar of spaghetti sauce. Cook the ground beef and sausage ahead of time to make this meal even quicker.

How to make Slow Cooker Lasagna:

Brown the Meat: Cook ground beef (or Italian sausage) with onion and garlic until browned. Drain, then stir in your favorite marinara sauce and set aside.

Cheese Mixture: In a mixing bowl, combine mozzarella, cottage cheese, and parmesan cheese.

Assemble: Spread a thin layer of meat sauce on the bottom of the slow cooker, then layer in uncooked lasagna noodles (broken to fit), meat sauce, and ricotta cheese mixture. Repeat the layers.

Cook and Serve: Cover and cook on low for 3-4 hours until noodles are tender. Add shredded mozzarella in the last 20 minutes, then serve this crockpot lasagna topped with fresh basil and parmesan. Make sure to try my Skillet Lasagna if you need something quicker.
