Prep & Cook Time

• Prep Time: 10 minutes
• Cook Time: 180 minutes (3 hours)
• Total Time: 190 minutes (3 hours 10 minutes)
• Servings: 15

Ingredients

• ½ lb lasagna noodles (regular or oven-ready, uncooked)
• 1 lb Italian sausage (bulks, or links with casings removed)
• ½ lb ground beef
• 1 cup onion (chopped, about 1 large onion)
• 2 cloves garlic (minced)
• 28 oz can of tomatoes (cut up, undrained)
• 12 oz can of tomato paste
• 2 teaspoon sugar
• 2 teaspoon salt
• 1 ½ teaspoon dried basil leaves
• ⅕ teaspoon fennel seed
• ¼ teaspoon coarse black pepper
• 15 oz ricotta cheese
• 1 large egg (beaten)
• 1 tablespoon dried parsley flakes (or 2 teaspoon fresh minced parsley)
• ½ teaspoon salt
• ½ teaspoon coarse black pepper
• 4 cups shredded mozzarella cheese
• ¾ cup Parmesan cheese

Instructions

1. In a large skillet over medium-high heat, cook the Italian sausage, ground beef, chopped onion, and minced garlic until the meat is browned and the onion is tender. Drain any excess fat.
2. Stir in the undrained cut-up tomatoes, tomato paste, sugar, 2 teaspoons salt, dried basil, fennel seed, and ¼ teaspoon coarse black pepper. Bring to a gentle simmer, then remove from heat.
3. In a separate bowl, combine the ricotta cheese, beaten egg, dried parsley flakes, ½ teaspoon salt, and ½ teaspoon coarse black pepper. Mix until well blended.
4. Spread about 1 ½ cups of the meat sauce evenly over the bottom of a 6-quart or larger slow cooker.
5. Arrange a single layer of uncooked lasagna noodles over the sauce, breaking them to fit as needed.
6. Dollop and spread one-third of the ricotta cheese mixture over the noodles. Sprinkle with 1 cup of the shredded mozzarella cheese and 3 tablespoons of the Parmesan cheese. Spoon about 1 ½ cups of meat sauce over the cheeses.
7. Repeat the layering process (noodles, ricotta mixture, mozzarella, Parmesan, sauce) two more times.
8. For the final layer, top with the remaining meat sauce, ensuring noodles are fully covered. Sprinkle the remaining 1 cup of mozzarella cheese and the remaining Parmesan cheese over the top.
9. Cover and cook on LOW for 3 hours, or until the noodles are tender and the cheese is melted and bubbly. Turn off the slow cooker, uncover, and let the lasagna rest for 20-30 minutes before serving to allow it to set.

Variations

• No-Boil Noodle Trick: Use oven-ready lasagna noodles for guaranteed perfect, non-mushy results every time.
• Vegetable Boost: Stir a layer of fresh baby spinach or thinly sliced zucchini between the cheese layers as you assemble.
• Spice It Up: Add a pinch of red pepper flakes to the meat sauce for a subtle kick of heat.
• Individual Servings: Layer the ingredients in small, oven-safe bowls or ramekins placed inside the slow cooker for personal-sized lasagnas.

Tips for Success

• Letting the lasagna rest after cooking is crucial; it firms up and makes serving much cleaner.
• Ensure every noodle is completely covered with sauce in the final layer to prevent dry, crunchy edges.
• For easier cleanup, consider using a slow cooker liner before you begin assembling.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, place individual portions in the microwave until warmed through, or cover and reheat in a 350°F oven for about 20 minutes.

FAQ

Can I use only ground beef?

Yes, you can substitute the 1 lb of Italian sausage with an additional 1 lb of ground beef for a simpler flavor profile.

Do I need to cook the noodles first?

No, the uncooked noodles soften perfectly during the slow cooking process thanks to the moisture in the sauce.

Can I prepare this the night before?

You can assemble the layers in the slow cooker insert, cover it tightly, and refrigerate overnight. Let it sit at room temperature for 30 minutes before starting the cooker in the morning.

My slow cooker is smaller than 6 quarts. Can I still make this?

For a smaller (4-5 quart) cooker, we recommend halving the recipe to prevent overflow and ensure even cooking.

What can I use instead of fennel seed?

If you don’t have fennel seed, you can simply omit it. A small pinch of anise seed or a teaspoon of Italian seasoning can be a rough substitute in a pinch.

Why is there sugar in the sauce?

The sugar helps to balance the natural acidity of the tomatoes, creating a richer, more rounded sauce flavor.
