🧾 Ingredients:
Main:
-
1 ½ lbs ground beef (or ground turkey)
-
1 medium onion, diced
-
3 cloves garlic, minced
-
3 medium zucchinis, sliced into ¼-inch half moons or rounds
-
1 red bell pepper, diced (optional, for added color and sweetness)
-
1 (14.5 oz) can diced tomatoes, drained
-
1 (8 oz) can tomato sauce
-
2 tsp Italian seasoning
-
½ tsp paprika
-
Salt and black pepper, to taste
-
1½ cups shredded cheddar cheese
-
1 cup shredded mozzarella cheese
-
2 tbsp olive oil or butter
Optional Add-ins:
-
½ cup chopped mushrooms
-
½ tsp crushed red pepper flakes (for heat)
-
¼ cup grated Parmesan cheese (for topping)
🍳 Instructions:
Step 1: Prepare the Zucchini
-
Slice zucchini and lightly salt them. Let them sit in a colander for 10 minutes to draw out excess moisture.
-
Pat dry with paper towels. This step helps prevent a watery casserole.
Step 2: Cook the Beef Mixture
-
In a large skillet over medium heat, add 1 tbsp olive oil.
-
Sauté diced onion (and bell pepper if using) for about 3–4 minutes until soft.
-
Add garlic and cook for 1 minute.
-
Add ground beef, breaking it up with a spatula. Cook until browned and no longer pink. Drain excess fat if needed.
-
Stir in the diced tomatoes, tomato sauce, Italian seasoning, paprika, salt, and pepper.
-
Let the mixture simmer on low for 5–10 minutes to let flavors meld.
Step 3: Sauté the Zucchini
-
In another pan, heat 1 tbsp olive oil or butter over medium heat.
-
Lightly sauté zucchini slices for 4–5 minutes until slightly tender (don’t overcook—they’ll finish in the oven).
Step 4: Assemble the Casserole
-
Preheat oven to 375°F (190°C).
-
Grease a 9×13-inch baking dish.
-
Layer half of the zucchini slices on the bottom.
-
Spoon half of the beef mixture on top.
-
Sprinkle half of the cheddar and mozzarella cheese.
-
Repeat with remaining zucchini, beef mixture, and cheeses.
Step 5: Bake
-
Cover with foil and bake for 20 minutes.
-
Remove foil and bake an additional 10–15 minutes until cheese is bubbly and golden.
-
Let it rest 10 minutes before serving to help it set.
🧀 Optional Topping:
-
Sprinkle with Parmesan cheese and chopped fresh parsley before serving.
🥄 Serving Suggestions:
-
Great with a side salad, garlic bread, or steamed green beans.
-
Leftovers reheat well and can be frozen for up to 2 months.
