Ingredients

For Slow Cooker Ravioli Spinach Lasagna

• 1 tablespoon olive oil

• 1 chopped onion

• 2 minced garlic cloves

• 1 pound ground beef

• 1 teaspoon salt

• 1/2 teaspoon black pepper

• 1 (24-ounce) jar marinara sauce

• 1 (25-ounce) package beef ravioli

• 1 (10-ounce) package fresh spinach

• 2 cups shredded mozzarella cheese

• 1/2 cup grated Parmesan cheese

• 1 teaspoon dried Italian herbs

• 1/4 teaspoon red pepper flakes (optional)

Step-by-Step Instructions

Step 1: Sauté the Aromatics

Heat olive oil in a skillet over medium heat.
Add the chopped onion and cook until soft and translucent, about 5 minutes.

Step 2: Add Garlic

Stir in the minced garlic and cook for about 1 minute until fragrant.

Step 3: Brown the Beef

Add the ground beef, season with salt and black pepper, and cook until fully browned. Break the meat apart with a spoon as it cooks.

Step 4: Mix with Marinara

Add half of the marinara sauce directly into the beef mixture.
Stir well and remove the skillet from heat.

Step 5: Prepare the Slow Cooker

Pour a thin layer of the remaining marinara sauce into the bottom of your slow cooker.
This prevents sticking and adds flavor to the base.

Step 6: Create the Layers

Now begin assembling the lasagna:

Layer 1

• Half of the beef ravioli

• Half of the meat sauce mixture

• Half of the fresh spinach

• Half of the mozzarella cheese

• Half of the Parmesan cheese

Layer 2

Repeat:

• Ravioli

• Meat sauce

• Spinach

• Mozzarella

• Parmesan

Step 7: Season the Top

Sprinkle dried Italian herbs and optional red pepper flakes over the final cheese layer.

Step 8: Slow Cook

Cover the slow cooker and cook on:

• LOW for 4–6 hours
  or

• HIGH for 2½ hours

The lasagna should be bubbly, melted, and completely heated through.

Step 9: Serve

Let the lasagna rest for 5–10 minutes so it sets nicely.
Garnish with extra Parmesan or freshly chopped basil before serving.
