Prep & Cook Time

Prep Time: 10 minutes

Cook Time: 180 minutes (3 hours)

Total Time: 190 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, brown the Italian sausage, ground beef, chopped onion, and minced garlic. Drain any excess fat.
2. To the meat mixture, add the undrained cut-up tomatoes, tomato paste, sugar, 2 teaspoons salt, dried basil, fennel seed, and ¼ teaspoon coarse black pepper. Stir well and bring to a simmer. Let it simmer for 5 minutes, 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.
4. Spread about 1 cup of the meat sauce onto the bottom of a 6-quart or larger slow cooker.
5. Layer ingredients in this order over the sauce: a single layer of uncooked lasagna noodles (breaking them to fit as needed), ⅓ of the ricotta mixture, 1 cup of shredded mozzarella, and a generous sprinkling of Parmesan cheese. Top with about 1 ½ cups of meat sauce.
6. Repeat this layering sequence two more times. For the final layer, after the last layer of noodles, finish with the remaining meat sauce, the remaining shredded mozzarella cheese, and the remaining Parmesan cheese.
7. Cover and cook on LOW for 3 hours, or until the noodles are tender and the cheese is melted and bubbly. Unplug the slow cooker and let the lasagna stand, covered, for 20-30 minutes before serving to allow it to set for cleaner slices.

Variations

• Vegetable Boost: Add a layer of thinly sliced zucchini, spinach, or sautéed mushrooms between the cheese and sauce layers.
• No-Boil Trick: For a firmer texture, soak regular (not oven-ready) noodles in hot water for 15 minutes before layering.
• Meatless Version: Omit the sausage and beef, and use a hearty vegetable-based sauce or a plant-based meat substitute.
• Individual Servings: Layer the ingredients in small, oven-safe dishes or mason jars that fit inside your slow cooker for personalized portions.

Tips for Success

• Ensure your slow cooker is at least 6 quarts to accommodate all the layers without bubbling over.
• Letting the lasagna rest after cooking is crucial; it allows the layers to firm up, making it much easier to serve.
• For the best texture, use whole-milk ricotta and shred your own mozzarella from a block, as pre-shredded cheese contains anti-caking agents that can make the sauce grainy.

Storage & Reheating

Store leftover lasagna in an airtight container in the refrigerator for up to 4 days. To reheat, place individual portions in the microwave or warm larger portions, covered with foil, in a 350°F oven until heated through. You can also freeze assembled but uncooked layers or fully cooked portions for up to 3 months.

FAQ

Can I use no-boil/oven-ready noodles?

Yes, they work perfectly in this recipe. No preparation is needed; just layer them in uncooked as directed.

Do I have to brown the meat first?

Yes, it’s essential for flavor and texture. Browning cooks off excess fat and develops a deeper, richer taste in the sauce.

Can I cook this on HIGH to save time?

It’s not recommended. Cooking on LOW allows the flavors to meld and the noodles to cook evenly without becoming mushy. Cooking on HIGH may result in overcooked edges and an undercooked center.

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

You can halve the recipe for a smaller slow cooker, or layer the ingredients in a taller, narrower configuration, ensuring you leave at least 1 inch of space at the top.

Why is there an egg in the ricotta mixture?

The egg acts as a binder, helping the ricotta layer hold its structure and not become watery during the long cooking process.

What can I use instead of fennel seed?

If you don’t have fennel seed, you can simply omit it. For a similar aromatic note, a tiny pinch of anise seed or a ¼ teaspoon of Italian seasoning blend can be used.
