Ingredients:

  • 3 medium zucchini, thinly sliced lengthwise

  • 1 lb ground turkey or lean ground beef

  • 2 cups low-sugar marinara sauce

  • 1 cup ricotta or cottage cheese

  • 1 egg

  • 1½ cups shredded mozzarella

  • ¼ cup grated Parmesan

  • 1 tsp Italian seasoning

  • ½ tsp garlic powder

  • ½ tsp salt

  • Olive oil spray for the slow cooker

  • Optional: fresh basil or parsley for serving

 

Instructions:

  1. Prep the zucchini
    Slice zucchini into long thin strips. Lay them on paper towels, sprinkle with salt, and let sit for 15 minutes to draw out moisture. Pat dry.

  2. Brown the meat
    In a skillet, cook turkey or beef with garlic powder and Italian seasoning until browned. Stir in marinara and set aside.

  3. Mix the cheese layer
    In a bowl, combine ricotta, egg, and a pinch of salt.

  4. Layer it up
    Spray slow cooker with olive oil. Start with a little sauce, then layer zucchini slices, meat sauce, ricotta mix, and mozzarella. Repeat 2–3 times. Top with Parmesan.

  5. Cook low and slow
    Cover and cook on low for 4–5 hours or high for 2–3 hours, until zucchini is tender and lasagna is set.

  6. Rest and serve
    Turn off heat and let sit uncovered for 15–20 minutes before slicing. Garnish with fresh basil or parsley.

 

Sarah’s Tips:

  • Less liquid? Place a paper towel under the lid during the last hour to absorb moisture.

  • Make it vegetarian: Skip the meat and layer in sautéed mushrooms or spinach.

  • Want more texture? Mix almond flour or crushed gluten-free crackers into the cheese layer.

  • Leftovers: Tastes even better the next day — great for meal prep!

This Slow Cooker Zucchini Lasagna gives you all the comfort of a cheesy, saucy baked dish — without the oven or the heaviness. It’s the kind of feel-good dinner you can make on a hot day and still feel amazing afterward.
