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:
-
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. -
Brown the meat
In a skillet, cook turkey or beef with garlic powder and Italian seasoning until browned. Stir in marinara and set aside. -
Mix the cheese layer
In a bowl, combine ricotta, egg, and a pinch of salt. -
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. -
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. -
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!
