There’s something wonderfully comforting about a baked pasta dish, especially one that doesn’t ask you to boil pasta, make a sauce from scratch, or spend much time in the kitchen. This Slow Cooker 4-Ingredient Ravioli Bake keeps things incredibly simple while still giving you a cozy, cheesy dinner.
The ravioli cooks right in the slow cooker with marinara sauce, Italian sausage, and plenty of melted mozzarella. As it simmers, the sauce works its way into the pasta while the cheese melts into a bubbly, savory topping.
It’s an easy choice for busy weeknights, casual Sunday dinners, or those evenings when you want something hearty without a pile of dishes afterward. Just layer everything in the crockpot, let it cook, and dinner is nearly done.
Getting A Saucy, Cheesy Ravioli Bake
The key here is using refrigerated or frozen ravioli that can cook directly in the slow cooker. There’s no need to boil it first.
For the sausage, Italian sausage adds plenty of seasoning on its own. Brown it before layering if you have a few extra minutes; this gives it better flavor and helps prevent excess grease from ending up in the finished dish.
Don’t stir the mozzarella through the entire bake. Saving it for the top lets it melt into a gooey layer without becoming lost in the sauce.
Ingredients You’ll Need
You only need four main ingredients for this simple slow cooker dinner:
- Ravioli, refrigerated or frozen
- Italian sausage
- Marinara sauce
- Shredded mozzarella cheese
How To Make Slow Cooker 4-Ingredient Ravioli Bake
Step 1: Cook the sausage. Remove the Italian sausage from its casings if necessary and brown it in a skillet over medium heat, breaking it into small pieces as it cooks. Drain any excess grease. If you’re using pre-cooked sausage, simply slice or crumble it into bite-sized pieces.
Step 2: Start layering. Lightly grease the slow cooker, then spread a little marinara sauce over the bottom. Add about half of the ravioli, followed by half of the cooked sausage and another layer of marinara.
Step 3: Add the remaining ingredients. Layer in the rest of the ravioli, sausage, and marinara sauce. Try to make sure the ravioli is coated with sauce so the edges don’t dry out during cooking.
Step 4: Slow cook. Cover and cook on LOW for about 3–4 hours, or until the ravioli is tender and heated through. Cooking times can vary depending on your slow cooker and whether you use refrigerated or frozen ravioli, so start checking toward the earlier end of the range.
Step 5: Add the cheese. Sprinkle the mozzarella evenly over the top during the final 15–20 minutes of cooking. Cover again and let it cook until the cheese is completely melted and gooey.
Step 6: Let it settle. Turn off the slow cooker and let the ravioli bake rest for about 5–10 minutes before serving. This gives the sauce a chance to thicken slightly and makes it easier to scoop.
Frequently Asked Questions
Can I Use Frozen Ravioli?
Yes. Frozen ravioli works well and can usually go straight into the slow cooker without thawing. You may need a little extra cooking time compared with refrigerated ravioli.
Do I Need To Boil The Ravioli First?
No. That’s one of the reasons this recipe is so convenient. The ravioli cooks in the marinara sauce as it heats.
Can I Use Ground Beef Instead Of Sausage?
Absolutely. Ground beef is a good substitute if that’s what you have. Add a little Italian seasoning, garlic powder, or dried oregano if you want to bring in some of the flavor that Italian sausage provides.
How Do I Know When It’s Done?
The ravioli should be tender when pierced with a fork, and the filling should be hot throughout. If you’re unsure, test a ravioli from the center of the slow cooker rather than relying only on the edges.
Can I Add More Cheese?
Of course. Mozzarella gives you that classic melty topping, but a little grated Parmesan can be sprinkled over the top just before serving for extra savory flavor.
Can I Make It Ahead?
You can brown the sausage and have the other ingredients ready ahead of time, but it’s best to assemble and cook the ravioli close to serving time. Ravioli sitting in sauce for too long before cooking can become overly soft.
Recipe Variations
Make It Spicy
Use hot Italian sausage and a marinara sauce with red pepper flakes for a little extra heat.
Add Spinach
Stir a few handfuls of fresh baby spinach into the layers. It will wilt as the ravioli cooks and adds some color without requiring much extra preparation.
Try A Different Cheese
Replace some or all of the mozzarella with an Italian cheese blend. Provolone or a little Parmesan can also add more depth.
Use Cheese Ravioli
Cheese-filled ravioli is especially good here because it pairs naturally with the marinara and sausage. Meat-filled ravioli works too if you want an even heartier dish.
Add Mushrooms
Thinly sliced mushrooms can be added between the layers. For the best texture, sauté them briefly with the sausage before assembling the bake.
Storage
Store leftover ravioli bake in an airtight container in the refrigerator for up to 3–4 days. Reheat individual portions in the microwave until hot, or warm larger portions in a covered oven-safe dish at 350°F until heated through. If the pasta seems dry after refrigeration, add a small spoonful of marinara sauce before reheating.
Freezing is possible, although the ravioli may become a little softer after thawing. For the best texture, freeze leftovers in individual portions and thaw them overnight in the refrigerator before reheating.
What To Serve With Slow Cooker 4-Ingredient Ravioli Bake
This ravioli bake is hearty enough to serve on its own, but a simple side makes the meal feel complete. I like pairing it with a crisp green salad, roasted broccoli, or some steamed green beans, and a little garlic bread is always welcome for scooping up the extra marinara sauce.
Once you’ve got the four ingredients layered in the slow cooker, there’s very little left to do. It’s the kind of dinner worth keeping in your back pocket for a busy day when you want something warm, filling, and wonderfully uncomplicated.
Slow Cooker 4-Ingredient Ravioli Bake
Ingredients
- 1 25-ounce bag frozen cheese ravioli, no need to thaw
- 1 24-ounce jar marinara sauce
- 2 cups shredded mozzarella cheese
- ½ cup grated Parmesan cheese
Instructions
- Layer the sauce: Lightly grease the inside of a 6-quart slow cooker. Spread about ½ cup of marinara sauce over the bottom.
- Add the ravioli: Arrange a layer of frozen ravioli over the sauce, keeping them as evenly distributed as possible.
- Build the layers: Spoon more marinara sauce over the ravioli, then sprinkle with some of the mozzarella and Parmesan. Repeat the layers until all the ravioli, sauce, and cheese have been used. Finish with a generous layer of cheese on top.
- Slow cook: Cover and cook on LOW for 3–4 hours, or until the ravioli are tender and heated through. Avoid lifting the lid too often, as this can extend the cooking time.
- Rest and serve: Turn off the slow cooker and let the ravioli bake rest for about 5–10 minutes. Spoon into bowls and serve warm.
