Introduction

This Slow Cooker Sausage and Peppers Ravioli Lasagna blends two Italian favorites — lasagna and ravioli — into a comforting, hands-off meal.
Layers of frozen cheese ravioli, browned Italian sausage, sautéed bell peppers and onions, and plenty of melted cheese come together
in the slow cooker to create an easy, flavorful dinner. It’s ideal for busy weeknights, potlucks, or any time you want a hearty, family-friendly dish with minimal effort.

Ingredients

To make this ravioli lasagna, gather:

• 1 pound Italian sausage (mild or spicy, to taste)
• 1 yellow onion, chopped
• 1 red bell pepper, chopped
• 1 yellow bell pepper, chopped
• 1 green bell pepper, chopped
• 3 cups marinara sauce (store-bought or homemade)
• 1 package (25 oz) frozen cheese ravioli
• 2 cups shredded mozzarella cheese
• 1/2 cup grated Parmesan cheese
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• 1/2 teaspoon garlic powder
• Salt and pepper to taste

Optional substitutions:

• Use ground turkey or chicken sausage for a lighter version.
• For a vegetarian option, replace the sausage with sautéed mushrooms or seasoned tofu crumbles.

Instructions

Step 1: Cook the Sausage

In a medium skillet over medium heat, cook the Italian sausage until browned and cooked through, breaking it into bite-sized pieces. Drain excess fat.

Step 2: Sauté the Vegetables

Add the chopped onion and bell peppers to the skillet with the sausage and cook another 3–5 minutes, until the vegetables soften but still hold some texture.

Step 3: Layer in the Slow Cooker

Spread a thin layer of marinara sauce across the bottom of the slow cooker. Arrange a single layer of frozen ravioli over the sauce. Spoon a portion of the sausage and pepper mixture over the ravioli, then sprinkle with mozzarella and Parmesan. Repeat layers — sauce, ravioli, sausage and peppers, cheese — until all ingredients are used, finishing with a top layer of cheese.

Step 4: Season and Cook

Sprinkle the dried oregano, basil, garlic powder, and season with salt and pepper over the top layer of cheese. Cover and cook on low for 4–5 hours, or until the ravioli are tender and the cheese is melted and bubbly.

Step 5: Rest and Serve

Let the lasagna rest for about 10 minutes before slicing to help it set. Serve warm.

Helpful Tips

• Use fresh mozzarella slices for a creamier, meltier texture on top.
• For a crisp top, transfer the cooked dish to an oven-safe pan and broil for 2–3 minutes, watching carefully to avoid burning.
• Swap the marinara for a spicy arrabbiata sauce if you prefer more heat.
• Partially thawing frozen ravioli for 15–20 minutes before assembling helps ensure even cooking in the slow cooker.
• A 6-quart slow cooker works well for layering without overcrowding.

Serving Suggestions

Pair this hearty lasagna with a crisp green salad — Caesar, arugula with lemon and olive oil, or a simple mixed greens salad.
Garlic bread, toasted baguette slices, or crusty Italian rolls make great accompaniments. For a relaxed dinner, offer a glass of red wine such as Chianti or Merlot to complement the rich flavors.

Frequently Asked Questions

Can I use fresh ravioli instead of frozen?

Yes. If using fresh ravioli, reduce the slow cooker time to about 2–3 hours on low to avoid overcooking.

Can I assemble this ahead of time?

Absolutely. Assemble the layers in the slow cooker insert, cover, and refrigerate for up to 24 hours. When ready to cook, set the slow cooker to low and allow the full cooking time.

What can I use if I don’t have Italian sausage?

Ground beef, ground turkey, or chicken sausage will all work. Season ground meat with Italian seasoning and a little garlic to boost flavor.

How do I make this spicier?

Choose spicy Italian sausage, add red pepper flakes to the sauce, or stir in a spoonful of hot sauce to the marinara before layering.
