Meat and Vegetables
- 1 lb lean ground beef (85% lean or higher)
- 2 medium fresh zucchinis, washed and thinly sliced
- 1 medium onion, diced
- 2 cloves garlic, minced
- 1 can (14.5 oz) diced tomatoes with juices
Cheese
- 1 cup shredded mozzarella cheese
- 1 cup shredded cheddar cheese
Seasonings and Oils
- 1 tbsp olive oil
- 1 tsp Italian seasoning
- Salt, to taste
- Black pepper, to taste
- Prep Your Ingredients: Wash and thinly slice the zucchinis. Dice the onion and mince the garlic. These fresh ingredients will provide texture and flavor throughout the dish.
- Cook the Ground Beef: Heat olive oil in a large skillet over medium-high heat. Add the ground beef, breaking it apart with a wooden spoon. Season with salt, pepper, and Italian seasoning. Cook until no pink remains and beef is browned, about 6–8 minutes. Remove excess grease if needed.
- Sauté Onions and Garlic: Push beef to one side of the skillet and add diced onions and minced garlic. Cook until fragrant and translucent, about 3–4 minutes, enhancing the casserole’s base flavor.
- Combine Beef with Tomatoes: Pour in diced tomatoes with their juices. Stir well and let simmer for 5 minutes to meld the flavors into a juicy, robust filling.
- Layer the Casserole: Preheat oven to 375°F (190°C). Grease a casserole dish. Arrange half of the zucchini slices evenly. Spread half of the beef and tomato mixture over the zucchini, then sprinkle a layer of cheese. Repeat with remaining zucchini and beef mixture, topping with remaining cheese.
- Bake Until Golden: Bake the casserole for 25 to 30 minutes, until cheese is bubbly and golden and zucchini is tender but holds its shape.
- Rest and Serve: Let the casserole rest for 5 minutes before slicing. This helps the layers set and makes serving easier.
Notes
- Use fresh, firm zucchini to prevent excess wateriness and maintain texture.
- Salt sliced zucchini and let it sit before assembling to drain excess moisture.
- Slice zucchini evenly for uniform cooking and presentation.
- Brown the beef well for additional flavor through caramelization.
- Choose a blend of good melting cheeses for a creamy, gooey top layer.
- Rest casserole after baking for better texture and cleaner slicing.
