Ingredients You’ll Need
The beauty of this recipe lies in its simplicity: just a handful of everyday ingredients that come together to create a dish bursting with flavor. Each component adds something special, from the juicy ground beef providing rich savoriness, to the fresh zucchini offering subtle sweetness and a tender bite, and the cheeses bringing that luscious, golden finish.
- 1 lb ground beef: Choose lean or regular ground beef depending on your preference for richness and fat content.
- 3 medium zucchinis, sliced: Fresh zucchinis add wonderful moisture and a slight crunch that balances the beef.
- 1 onion, chopped: The onion infuses the beef with natural sweetness and depth.
- 2 cloves garlic, minced: Garlic gives an aromatic kick that enhances the entire casserole.
- 1 can (14.5 oz) diced tomatoes, drained: Adds acidity and a subtle natural sweetness, preventing the dish from becoming too heavy.
- 1/2 cup tomato sauce: Creates a saucy base that ties all ingredients together.
- 1 teaspoon dried oregano: Offers a warm, herbaceous note that complements the tomato flavors perfectly.
- 1 teaspoon dried basil: Brings freshness and a hint of aromatic sweetness to the dish.
- 1/2 teaspoon salt: Enhances all other flavors without overpowering them.
- 1/4 teaspoon black pepper: Adds just enough subtle heat and sharpness.
- 1 cup shredded mozzarella cheese: Melts beautifully, providing stretch and creaminess on top.
- 1/2 cup grated Parmesan cheese: Gives a nutty, savory finish with a slightly crisp texture when baked.
- 1 tablespoon olive oil: For sautéing and bringing out the natural flavors of the beef and vegetables.
How to Make Ground Beef and Zucchini Casserole Recipe
Step 1: Preheat and Prepare
Start by setting your oven to 375°F (190°C). Preheating is important so the casserole bakes evenly and crisps up nicely, especially the cheesy topping.
Step 2: Brown the Beef
In a large skillet, warm the olive oil over medium heat. Add the ground beef, breaking it apart with a wooden spoon or spatula as it cooks. Cook for about 6 to 8 minutes until the beef is nicely browned. If there’s excess fat, feel free to drain it off to keep the casserole from becoming too greasy.
Step 3: Sauté Onion and Garlic
To the skillet with browned beef, add the chopped onion and minced garlic. Sauté for 3 to 4 minutes until the onions become soft and translucent, and the garlic releases its fragrant aroma. This step builds a flavorful base for the casserole.
Step 4: Combine Tomatoes and Seasonings
Pour in the drained diced tomatoes and tomato sauce, then stir in oregano, basil, salt, and pepper. Let the mixture simmer gently for about 5 minutes so the flavors meld and the sauce thickens slightly.
Step 5: Prepare the Casserole Layers
Grease a 9×13-inch casserole dish to prevent sticking. Lay half of the zucchini slices evenly on the bottom. These layers provide a lovely, moist vegetable component that balances the rich beef.
Step 6: Add the Beef Mixture
Spread half of your warm beef and tomato mixture over the zucchini layer. Then, add another layer of the remaining zucchini slices, followed by the rest of the beef mixture. Layering ensures every bite has a balanced flavor and texture.
Step 7: Top with Cheese
Generously sprinkle the shredded mozzarella and grated Parmesan over the top. These cheeses will melt into a bubbly, golden crust that adds indulgent richness to the casserole.
Step 8: Bake to Perfection
Cover the casserole with aluminum foil and bake for 30 minutes to allow everything to meld together and cook through. Then, remove the foil and bake for an additional 10 minutes so the cheese browns beautifully and develops a delicious crispy finish.
How to Serve Ground Beef and Zucchini Casserole Recipe
Garnishes
Fresh garnishes like a sprinkle of chopped basil or parsley can brighten the rich casserole and add a pop of color. A light drizzle of extra virgin olive oil or a dash of crushed red pepper flakes also elevates the flavors if you love a bit of heat.
Side Dishes
This casserole pairs wonderfully with simple sides such as a crisp green salad with vinaigrette, garlic bread for soaking up the juices, or even roasted potatoes for added heartiness. The freshness of the salad balances the savory depth in the main dish.
Creative Ways to Present
For an inviting presentation, serve the casserole directly from the baking dish with a large spoon, allowing guests to see all the layered goodness. Alternatively, individual portions can be scooped neatly onto colorful plates and topped with a spoonful of sour cream or a sprinkle of fresh herbs to impress your guests.
Make Ahead and Storage
Storing Leftovers
You can store any leftover Ground Beef and Zucchini Casserole Recipe in an airtight container in the refrigerator for up to 3 days. This makes for a quick and satisfying meal the next day — just reheat and enjoy.
Freezing
This casserole freezes extremely well. Wrap it tightly in plastic wrap and aluminum foil or place in a freezer-safe container, then freeze for up to 2 months. Thaw in the refrigerator overnight before reheating to preserve the texture.
Reheating
To reheat, warm individual portions in the microwave until heated through, or place the entire casserole back in a 350°F (175°C) oven, covered, for about 20 minutes. Remove the cover in the last 5 minutes to refresh the cheesy topping’s crispiness.
FAQs
Can I use other types of meat instead of ground beef?
Absolutely! Ground turkey, chicken, or even pork work well in this casserole. Just adjust the seasoning and cooking time slightly to suit the type of meat you choose.
Is it okay to use frozen zucchini slices for this recipe?
Fresh zucchini is recommended because it holds texture better after baking. Frozen zucchini tends to release excess water, which can make the casserole watery. If you must use frozen, be sure to thaw and squeeze out as much moisture as possible.
Can I make this recipe vegetarian?
Yes, by substituting the ground beef with a plant-based protein or cooked lentils. Adding extra vegetables like mushrooms or bell peppers can boost flavor and texture.
How spicy is the casserole? Can I add more heat?
This recipe is mild by default, but you can easily add crushed red pepper flakes or a dash of hot sauce during step 4 to give it a bit of a kick.
What’s the best way to slice the zucchini?
Slicing the zucchini into medium-thin rounds ensures they cook evenly and remain tender but not mushy in the casserole.
