Can I Use Fresh Ravioli Instead of Frozen for This Recipe?

Absolutely, you can use fresh ravioli, but watch the cooking time closely! Fresh ravioli cooks faster than frozen, so you’ll want to check it around the 3-hour mark to prevent it from turning to mush.

Slow Cooker Ravioli Lasagna Ingredients

• 25 oz (708 g) of frozen ravioli (5 cheese variety recommended)
• 1 lb (454 g) of ground beef (mild sausage is an alternative)
• 1 cup (150 g) of white onion, diced
• 1/2 tsp (2.5 g) of salt
• 1/4 tsp (1.25 g) of pepper
• 1/4 tsp (1.25 g) of garlic powder
• 1/2 tsp (2.5 g) of dried leaf oregano (not ground)
• 24 oz (680 g) of marinara sauce (Rao’s recommended)
• 8 oz (227 g) of shredded mozzarella cheese (about 2 cups)

How To Make Slow Cooker Ravioli Lasagna

1. Brown the Beef: In a medium-sized non-stick skillet over medium-high heat, combine the ground beef and diced onion. Sprinkle in the salt, pepper, garlic powder, and oregano. Cook until the beef is thoroughly browned, but let’s keep a bit of the juice for flavor.
2. Prep Your Slow Cooker: Give your slow cooker a good spray with non-stick cooking spray.
3. Layer on the Sauce: Pour half of the marinara sauce into the bottom of the slow cooker. Spread it out to cover the base.
4. Add the First Ravioli Layer: Now, toss in half the bag of ravioli right on top of that saucy base.
5. Stack on the Beef: Layer all of the cooked ground beef mixture evenly over the ravioli.
6. More Ravioli: Add the remaining ravioli over the beef layer.
7. Top with Sauce and Cheese: Drizzle the rest of the marinara sauce over the ravioli and sprinkle the mozzarella cheese evenly on top.
8. Cook Low and Slow: Cover the slow cooker and set it to cook on LOW for 4 hours. No peeking until it’s done!
9. Serve It Up: Once it’s perfectly cooked, serve up this cheesy goodness and watch it disappear.

How long should I cook the ravioli lasagna?

Cook on low for 4-6 hours. Keep an eye on the cheese—once it’s melted and bubbly, your lasagna is ready. Cooking times can vary, so check at the 4-hour mark.

Recipe Tips

• Choose Your Cheese Wisely: To get that perfect gooey texture, mix in some ricotta with the mozzarella on top; it adds a creamy twist that really ups the comfort factor.
• Keep It Saucy: Don’t skimp on the marinara sauce! Using a bit more than the recipe suggests ensures every bite is moist and flavorful because nobody likes a dry lasagna.
• Spice It Up: If you’re feeling adventurous, throw in some red pepper flakes while cooking the beef to give your lasagna a subtle kick that wakes up the taste buds.
• Layering Technique: For an even cook, make sure to spread each layer of ingredients evenly in the slow cooker, this keeps every bite as good as the last – it’s all about consistency!

Recipe Variations

• Vegetarian Delight: Swap the ground beef for a mix of mushrooms, zucchini, and bell peppers for a veggie version that still packs a hearty punch.
• Go Gluten-Free: Use gluten-free ravioli and ensure your marinara sauce is gluten-free to make this dish celiac-friendly without compromising on the taste.
• Different Meats, Different Treats: Instead of ground beef, try ground turkey or even Italian sausage for a different flavor profile that keeps things interesting.
• Extra Cheesy Please: Add layers of different cheeses like provolone and gouda between the ravioli layers for a cheesy explosion that’ll make cheese lovers swoon.

What To Serve With Ravioli Lasagna

How To Store Leftover Ravioli Lasagna

In The Fridge:

Place your leftover Ravioli Lasagna in an airtight container to keep it fresh. Ensure it cools down to room temperature before sealing it up. It will stay good for up to 3 to 4 days when stored properly.

In The Freezer:

Ravioli Lasagna can be stored in the freezer, but be aware that the pasta may become slightly softer upon reheating. To freeze, wrap it tightly in plastic wrap followed by aluminum foil. It will keep well for up to 2 months.

How To Reheat Leftover Ravioli Lasagna

Reheat your leftover Ravioli Lasagna in the oven at 350 degrees Fahrenheit until it’s heated through, which should take about 20 to 25 minutes. Cover it with foil to prevent the cheese from burning; or, you can microwave individual servings for 1-2 minutes, checking periodically.
