Introduction

This Ground Beef Zucchini recipe is a flavorful and comforting dish that combines tender zucchini slices with savory seasoned beef and melted mozzarella cheese. It’s perfect for a wholesome weeknight dinner that feels hearty without being heavy.

The dish is in a white rectangular baking dish with three visible layers. The bottom layer is a rich, browned ground meat sauce with a crumbly texture. Above this is a layer of thick, round zucchini slices, green on the outside and pale yellow inside, arranged in a row. The top layer is a golden-brown melted cheese that has bubbly and slightly browned spots, covering parts of the zucchini and chunks of red roasted bell pepper scattered on the surface. The dish sits on a white marbled texture surface with soft natural light. photo taken with an iphone --ar 4:5 --v 7

Ingredients

2 medium zucchini, sliced
1 tablespoon olive oil
1 small onion, diced
2 garlic cloves, minced
1 lb lean ground beef
2 tsp Italian seasoning
½ tsp kosher salt
½ tsp black pepper
28 oz can diced tomatoes, drained
2 cups shredded mozzarella cheese

Instructions

Step 1: Prepare the zucchini by sprinkling the slices with salt. Let them rest for about 10 minutes, then rinse to remove excess salt and pat dry with paper towels.
Step 2: In a large skillet, heat olive oil over medium heat. Add diced onion and minced garlic, cooking until softened and fragrant, about 3 minutes.
Step 3: Add the ground beef to the skillet, breaking it apart with a spoon. Cook until fully browned and no longer pink.
Step 4: Stir in the drained diced tomatoes, Italian seasoning, kosher salt, and black pepper. Cook for another 2 minutes, then remove from heat.
Step 5: Preheat your oven to 350°F (175°C). In a baking dish, layer a portion of the meat mixture, followed by a layer of zucchini slices, then sprinkle with mozzarella cheese. Repeat these layers until all ingredients are used, finishing with cheese on top.
Step 6: Bake uncovered for 20 to 25 minutes, until the cheese is melted and bubbly.
Step 7: Let the dish rest for 10 minutes before serving to allow the flavors to meld and make slicing easier.

Tips & Variations

For extra flavor, add a splash of red wine or a pinch of red pepper flakes to the meat mixture.
Use part-skim mozzarella for a lighter version, or add Parmesan cheese on top for a richer taste.
Try adding chopped fresh basil or parsley before serving for a fresh herbal note.
