Instructions

Step 1: Cook the Turkey

Heat 1 tablespoon of oil in a large sauce pot over medium heat. Add the ground turkey and cook for about 5 minutes, breaking it apart into bite-sized pieces until fully cooked. Transfer to a plate and drain excess liquid.

Step 2: Make the Sauce

Add the remaining tablespoon of oil to the pot. Sauté the diced onion for 5 minutes until softened. Add garlic and cook for 1 minute.

Return the turkey to the pot and stir in the drained diced tomatoes, tomato paste, Italian herbs, and salt. Bring to a boil and simmer for 3–5 minutes, until slightly thickened.

Step 3: Prepare the Cheese Mixture

In a large bowl, whisk the eggs. Stir in the cottage cheese and parmesan until well combined.

Step 4: Layer the Lasagna

Lightly oil or spray your slow cooker. Spread a thin layer of sauce on the bottom.

Add a single layer of uncooked lasagna noodles (break to fit and slightly overlap if needed). Spread 1/3 of the cottage cheese mixture over the noodles, then sprinkle 1/3 of the mozzarella on top.

Repeat layers two more times, ending with mozzarella cheese on top.

Step 5: Slow Cook

Cover and cook on low for 4–6 hours, or until noodles are tender.

Step 6: Rest Before Serving

Turn off the slow cooker and remove the lid. Let the lasagna rest for 20 minutes before slicing. This helps it firm up and hold its shape.

Notes

• Crock Pot Size: This recipe is written for a 6.5-quart slow cooker. If using a smaller one, reduce the amount per layer to fit.

• Drain Tomatoes Well: Properly draining prevents a watery sauce.

• Add Vegetables: Layer in sautéed spinach, zucchini slices, or mushrooms for added flavor and nutrition.

• Prevent Sticking: Lightly grease the crock before assembling.

• Make Ahead: Prepare the sauce a day in advance and refrigerate. You can also fully assemble the lasagna in the slow cooker insert, cover, and refrigerate overnight. If cooking from cold, add about 30 extra minutes to the cook time.
