Lazy Crockpot Lasagna
A hands-off, delicious lasagna made easy in a slow cooker using cheese ravioli instead of traditional noodles—perfect for busy weeknights.
I make this lazy crockpot lasagna on busy weeknights when I want all the cozy, layered flavor of lasagna without standing over the stove. It’s essentially a hands-off, saucy bake made in a slow cooker using cheese ravioli instead of lasagna noodles — perfect when you want comfort food with minimum fuss. If you like simple, set-and-forget pasta dinners, this is similar in spirit to the crockpot ravioli lasagna I tested last winter and becomes a family favorite fast.
Why you’ll love this dish
Lazy Crockpot Lasagna hits several sweet spots: it’s quick to assemble, budget-friendly, and kid-approved. Using cheese ravioli makes traditional layering unnecessary — you get that soft, pillowy pasta layer without boiling or handling fragile noodles. The slow cooker melds sausage, tomatoes, and ricotta into a comfort-forward filling while you take care of other things.
When to make it: weeknight dinners, potlucks, or a low-effort Sunday supper. It’s also forgiving if you need to double the batch for a crowd.
How this recipe comes together
Quick overview: brown and drain Italian sausage, stir in sauce and seasonings, then layer thin sauce, ravioli, spoonfuls of sauce and ricotta three times. Finish with shredded mozzarella and let the slow cooker do the rest. Expect about 4 hours on high or 6–7 hours on low. The result is a bubbling, sliceable casserole — easier than traditional lasagna and great for busy households.
What you’ll need
- 1 lb Italian sausage (mild or hot, turkey)
- 24 oz can pasta sauce (your favorite marinara)
- 28 oz can crushed tomatoes
- 2 tsp Italian seasoning
- 1 tsp garlic powder
- 25 oz package cheese ravioli (fresh, refrigerated, or frozen)
- 15 oz container ricotta cheese
- 8 oz mozzarella, shredded
Substitution notes:
- Swap ground beef or turkey for the sausage if you prefer (adjust seasoning).
- Use part-skim ricotta for a lighter version.
- Add ¼–½ cup grated Parmesan into the ricotta for extra umami.
- Frozen ravioli works — see Directions for timing details.
Step-by-step instructions
- Brown the sausage: Heat a large skillet over medium. Add the Italian sausage and break it up with a spoon. Cook until no pink remains, about 6–8 minutes. Drain off excess grease.
- Make the sauce: Return the drained sausage to the skillet (or into a bowl). Stir in the 24 oz pasta sauce, 28 oz crushed tomatoes, Italian seasoning, and garlic powder until combined.
- Prep the slow cooker: Spoon a thin layer of the meat sauce across the bottom of a 6-quart slow cooker to prevent sticking.
- Layer once: Place a single layer of ravioli evenly over the sauce. Spoon about one-third of the remaining meaty sauce over the ravioli in an even layer. Dollop about one-third of the ricotta across the sauce in spoonfuls.
- Repeat layers: Repeat the ravioli + one-third sauce + ricotta dollops two more times so you have three total layers. Finish by sprinkling the shredded mozzarella evenly on top.
- Cook: Cover and cook on HIGH for 4 hours or LOW for 6–7 hours, until the ravioli are tender and the cheese is bubbly. If using very thick refrigerated ravioli, add an extra 30 minutes on low.
- Rest and serve: Turn off the cooker and let rest 10–15 minutes before scooping so it holds together better.

Best ways to enjoy it
Serve hot straight from the slow cooker with:
- A crisp green salad (arugula, vinaigrette) to brighten the meal.
- Garlic bread or toasted sourdough for mopping up sauce.
- Steamed broccoli or roasted vegetables for a vegetable side.
For a plated look, scoop a portion with a slotted spoon so excess sauce drains, then sprinkle fresh basil or chopped parsley and extra grated Parmesan.
Storage and reheating tips
Refrigerate: Cool to room temperature within 2 hours and store in an airtight container for 3–4 days.
Reheat: Reheat single portions in the microwave until steaming (165°F internal). For larger portions, reheat covered in a 350°F oven until warmed through, about 20–30 minutes.
Freeze: Freeze portions in freezer-safe containers for up to 2 months. Thaw overnight in the fridge before reheating.
Food safety tip: When reheating leftovers, make sure the center reaches at least 165°F to destroy harmful bacteria.
Creative twists
- Meat-free: Replace sausage with sautéed mushrooms, lentils, or a plant-based crumbles for a vegetarian version.
- Veg-forward: Add layers of sautéed spinach, zucchini, or roasted eggplant between ravioli.
- Cheesy upgrade: Mix shredded fontina or provolone with the mozzarella for a richer top.
- Spicy: Add red pepper flakes or use hot Italian sausage for some heat.
- Alfredo spin: Swap half the crushed tomatoes with a jar of Alfredo sauce and use spinach ravioli for a creamy variation.
Your questions answered
Can I use frozen ravioli straight from the freezer?
A: Yes. Frozen ravioli will cook through in the slow cooker, but add about 30–45 minutes on LOW if your ravioli are large or very thick.
How do I know when it’s done?
A: The edges should bubble and the ravioli should be tender when pierced with a fork. The cheese on top should be melted and slightly golden.
Can I double the recipe?
A: You can double, but use two slow cookers or cook in batches. Overfilling one cooker can cause uneven cooking.
Will the ravioli get soggy?
A: Slow cookers create moist heat, so ravioli will be soft but not mushy if you follow times. Avoid over-cooking by checking at the lower end of the time range the first time you make it.
Can I make this ahead?
A: Assemble in the slow cooker insert, cover, and refrigerate for up to 24 hours. Add 30 minutes to the cooking time if starting from chilled.
