Ingredients Needed

Spaghetti sauce – This is a flexible choice! Use 6 cups of homemade spaghetti sauce with meat for a hearty version, or use jarred marinara sauce for a quick or vegetarian version. I recommend the Best Slow Cooker Spaghetti Sauce Recipe if you want to make a big batch and use some for lasagna.
Frozen cheese ravioli – Simply pick up a package of frozen cheese ravioli at the store – you don’t even need to thaw beforehand! Fresh or refrigerated ravioli can also work, but reduce the cooking time slightly.
Shredded mozzarella cheese – Layer in shredded mozzarella for melted, cheesy layers that tie the lasagna together.
Grated Parmesan cheese – Grated Parmesan adds more cheesiness, without making the lasagna too heavy.
Ricotta cheese – This is an optional addition for extra creaminess. It makes the lasagna rich, yet not overly dense.
Fresh basil – This is a must for a burst of herbal flavor! Add the fresh basil right before serving for an elevated touch.

How To Make Slow Cooker Ravioli Lasagna

Note: You can make ravioli lasagna in a round 4-quart slow cooker with 4 layers, or an oval 6-quart slow cooker with 2 layers.

Spread 1-2 cups of your spaghetti sauce on the bottom of the slow cooker.

Pro Tips

No need to thaw ravioli – just layer the pieces into the slow cooker frozen.
Spread the sauce on the bottom first to prevent sticking.
Layer everything evenly so the ravioli cooks through properly.
Let the lasagna rest for 5-10 minutes with the slow cooker turned off and the lid open before serving so that it sets slightly and slices more cleanly.
Make a big batch of Best Slow Cooker Spaghetti Sauce Recipe and save portions in the freezer for easy meals like this one! Simply add a frozen portion of sauce to the fridge the night before to thaw, and then assemble with the frozen ravioli when you’re ready.
To simplify prep even further, brown ground meat or sausage ahead of time and freeze meal-size portions. Grab a bag from the freezer along with the frozen ravioli and assemble!

Recipe Substitutions and Variations

For variation, try frozen cheese ravioli, spinach ravioli, or meat-filled ravioli.
Use Alfredo sauce for a white lasagna version.
Add cooked ground turkey or sausage to the sauce for a heartier meal.
For added nutrition, consider adding finely chopped spinach, mushrooms, or zucchini between layers.
Spice up the lasagna with red pepper flakes or a spicy marinara.

What to Serve With Slow Cooker Ravioli Lasagna

Serve up a classic, Italian-inspired meal with bowls of cheesy ravioli lasagna, accompanied by garlic bread, a fresh green salad, or Roasted Fall Vegetables. Add other single-veggie sides, such as Sautéed Green Beans with Garlic, Roasted Brussels Sprouts, or oven-roasted broccoli with extra Parmesan.

Don’t forget to garnish with pieces of fresh basil or chopped parsley for a fresh touch!
