Ingredients You'll Need
25 ounces frozen cheese ravioli: These replace traditional lasagna noodles and provide delicious layers of pasta and cheese. There's no need to thaw them first.
1 pound ground beef: Adds a hearty, savory flavor and makes the casserole filling enough for dinner.
48 ounces marinara sauce: Creates the rich tomato sauce that brings all the layers together. Use your favorite store-bought or homemade marinara.
2 cups shredded mozzarella cheese: Melts between the layers and creates a delicious cheesy topping.
How to Make Crockpot 4-Ingredient Ravioli Lasagna
Step 1: Brown the Ground Beef
Place the ground beef in a large skillet over medium-high heat.
Break it apart with a spatula and cook until completely browned, with no pink remaining.
Drain the excess grease thoroughly and set the cooked beef aside.
Step 2: Prepare the Slow Cooker
Lightly grease the inside of a 6-quart slow cooker with cooking spray or a little oil.
Spread approximately ½ cup of marinara sauce across the bottom. This creates a protective layer and helps prevent the ravioli from sticking.
Step 3: Add the First Layer of Ravioli
Arrange a single layer of frozen cheese ravioli over the marinara sauce.
Try to cover as much of the bottom as possible without overlapping too many pieces.
Step 4: Add the Ground Beef and Sauce
Spread some of the cooked ground beef over the ravioli.
Spoon a layer of marinara sauce over the beef, followed by a generous sprinkle of shredded mozzarella cheese.
Step 5: Repeat the Layers
Continue layering the frozen ravioli, cooked ground beef, marinara sauce, and mozzarella cheese until all the ingredients have been used.
Make sure to distribute the ingredients evenly so every serving has plenty of pasta, meat, sauce, and cheese.
Step 6: Finish with Sauce and Cheese
Pour the remaining marinara sauce over the top layer, making sure the ravioli are well covered.
Finish with the remaining shredded mozzarella cheese for a delicious cheesy topping.
Step 7: Slow Cook Until Tender
Cover the slow cooker with its lid and cook on LOW for 3–4 hours or HIGH for 1½–2½ hours.
The casserole is ready when the ravioli are tender, heated throughout, and the mozzarella cheese is melted.
Cooking times can vary depending on your slow cooker, so begin checking toward the earlier end of the recommended cooking time to avoid overcooking the pasta.
Step 8: Let It Rest and Serve
Turn off the slow cooker and let the ravioli lasagna rest for about 10 minutes before serving.
This short resting period helps the layers settle and makes it easier to scoop into individual portions.
Serve warm and enjoy all that delicious melted cheese and rich marinara sauce!
Tips for the Best Slow Cooker Ravioli Lasagna
Use Frozen Ravioli: Add the ravioli directly from the freezer. Thawing them beforehand can make them too soft during the slow cooking process.
Drain the Ground Beef Well: Removing excess grease prevents the sauce from becoming oily and helps maintain a better texture.
Don't Skip the Bottom Sauce Layer: Spreading marinara sauce across the bottom of the slow cooker helps prevent the pasta from sticking.
Cover the Ravioli with Sauce: Make sure the pasta is well coated with marinara so it cooks evenly and doesn't dry out.
Avoid Overcooking: Ravioli can become mushy if left in the slow cooker for too long. Check for tenderness toward the beginning of the cooking window.
Let It Rest Before Serving: Giving the casserole a few minutes to settle makes serving easier and helps the layers hold together.
What to Serve with Ravioli Lasagna
This hearty slow cooker dinner is delicious on its own, but a few simple side dishes can make it feel like a complete Italian-inspired meal.
Garlic bread or warm breadsticks are perfect for soaking up the extra marinara sauce. A fresh garden salad with Italian dressing adds a refreshing contrast to the rich, cheesy casserole.
You can also serve it with roasted broccoli, steamed green beans, or sautéed zucchini for an easy vegetable side.
If you're preparing dinner for a larger family gathering, add a simple Caesar salad and some warm dinner rolls.
How to Store and Reheat Leftovers
Allow the ravioli lasagna to cool slightly before transferring leftovers to an airtight container.
Refrigerate for up to 3–4 days.
To reheat, place an individual portion in a microwave-safe dish, cover loosely, and heat until warmed through. Add a small spoonful of marinara sauce if the pasta seems dry.
For larger portions, reheat in an oven-safe dish covered with foil at 325°F (165°C) until hot throughout.
You can also freeze leftovers in individual airtight containers for up to 2 months. Thaw overnight in the refrigerator before reheating. Keep in mind that the ravioli may become slightly softer after freezing and thawing.
Frequently Asked Questions
Do I need to thaw the frozen ravioli first?
No! One of the best things about this recipe is that you can add the ravioli directly from the freezer. There's no need to boil or thaw them before layering.
Can I use ground turkey instead of ground beef?
Absolutely. Ground turkey is a good alternative if you prefer a leaner option. Brown it thoroughly before adding it to the slow cooker.
Can I use a different type of ravioli?
Yes! Cheese ravioli works beautifully, but you can also experiment with beef-filled or spinach-and-cheese ravioli. Just keep in mind that the flavor of the finished casserole will change slightly.
Can I prepare this recipe ahead of time?
You can brown the ground beef ahead of time and refrigerate it in an airtight container. For the best pasta texture, assemble the layers shortly before cooking rather than leaving frozen ravioli sitting in the sauce for an extended period.
Why is my ravioli lasagna mushy?
This usually happens when the ravioli cook for too long or the slow cooker runs hotter than expected. Check the pasta toward the earlier end of the cooking time and turn off the slow cooker as soon as the ravioli are tender.
Can I make this without ground beef?
Yes! You can leave out the beef for a meatless version or replace it with your favorite plant-based ground alternative.
