Ingredients:

• 2 medium zucchini, sliced (about 2 pounds)
• 1 tbsp olive oil
• 1 small onion (diced)
• 2 garlic cloves (minced)
• 1 pound lean ground beef
• 2 tsp Italian seasoning
• 1/2 tsp kosher salt
• 1/2 tsp black pepper
• 1 28 ounce can diced tomatoes (drained)
• 2 cups shredded mozzarella cheese

Cooking Instructions:

This recipe is designed to be straightforward, but paying attention to a few details will ensure the best results. We’ll start by preparing our vegetables, then cooking our flavorful beef mixture, and finally assembling and baking this delightful casserole.

1. Preparing the Zucchini and Aromatics:
Begin by washing your two medium zucchini thoroughly. Trim off the ends. Now, you’ll want to slice the zucchini into rounds, aiming for about ¼-inch thickness. Don’t worry if they’re not perfectly uniform; we’re going for rustic here! The key is to have them thin enough to cook through nicely in the casserole. Next, prepare your aromatics. Finely dice one small onion. Mince your two garlic cloves. Having these ready to go will make the sautéing process quick and efficient.

2. Sautéing the Beef and Building Flavor:
Heat one tablespoon of olive oil in a large skillet or Dutch oven over medium-high heat. Once the oil is shimmering, add your diced onion. Sauté the onion for about 3-5 minutes, stirring occasionally, until it becomes translucent and slightly softened. This process will start to release its natural sweetness. Now, add your minced garlic to the skillet. Cook for another minute until fragrant, being careful not to burn the garlic as it can turn bitter quickly. Add the one pound of lean ground beef to the skillet. Break up the meat with a spoon and cook, stirring frequently, until it’s browned all over. Drain off any excess grease from the skillet to keep the casserole from being too oily. Once the beef is browned, stir in two teaspoons of Italian seasoning, half a teaspoon of kosher salt, and half a teaspoon of black pepper. Mix well to distribute the seasonings evenly throughout the ground beef. This is where the savory foundation of our casserole really starts to develop.

3. Incorporating the Tomatoes and Simmering:
Next, it’s time to add the tomatoes. Drain a 28-ounce can of diced tomatoes and add them directly to the skillet with the browned beef mixture. Stir everything together to combine. Let this mixture simmer for about 5-10 minutes over medium heat, allowing the flavors to meld together. This simmering period also helps to slightly reduce the liquid from the tomatoes, which is important for preventing a watery casserole. Give it a taste and adjust the salt and pepper if you feel it needs it. The aroma at this stage is incredible!

4. Assembling the Casserole Layers:
Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Now it’s time to assemble our delicious casserole. You can use a standard 9×13 inch baking dish for this. Start by spreading about half of the ground beef and tomato mixture evenly across the bottom of your prepared baking dish. This forms a flavorful base. Next, arrange about half of your sliced zucchini rounds in an even layer over the beef mixture. Don’t worry if there are small gaps; they will shrink as they cook. Sprinkle about half of your shredded mozzarella cheese (which is one cup) over the zucchini layer. Now, repeat the process: add the remaining ground beef and tomato mixture on top of the cheese, followed by the rest of the sliced zucchini, and finally, top everything with the remaining shredded mozzarella cheese. Ensure the cheese covers the zucchini as much as possible to create that wonderful, melty topping.

5. Baking to Golden Perfection:
Cover the baking dish tightly with aluminum foil. This step is crucial for ensuring the zucchini cooks through and steams gently without drying out the top. Place the covered casserole in your preheated oven and bake for 30 minutes. After 30 minutes, carefully remove the aluminum foil. Continue to bake for another 15-20 minutes, or until the mozzarella cheese is melted, bubbly, and has developed a beautiful golden-brown color. You’ll know it’s ready when you can easily pierce the zucchini with a fork. Let the casserole rest for about 5-10 minutes before serving. This resting period allows the casserole to set up slightly, making it easier to serve and preventing it from falling apart. Enjoy this comforting and flavorful Ground Beef Zucchini Casserole!

Conclusion:

There you have it – a delicious and satisfying Ground Beef Zucchini Casserole that’s sure to become a family favorite! This recipe truly shines because it’s incredibly versatile, wonderfully healthy thanks to the inclusion of fresh zucchini, and surprisingly easy to whip up on a busy weeknight. It’s a fantastic way to sneak extra vegetables into your meals without compromising on flavor, and the combination of savory ground beef, tender zucchini, and a creamy sauce is simply irresistible. I love serving this casserole with a simple side salad dressed with a light vinaigrette, or some crusty bread to sop up any extra deliciousness. For even more variety, consider adding other vegetables like diced bell peppers or mushrooms to the mix, or swap out the ground beef for ground turkey or even plant-based crumbles. Don’t be afraid to experiment with different cheeses for the topping – a sprinkle of Parmesan or a blend of cheddar and Monterey Jack are wonderful additions. I truly encourage you to give this Ground Beef Zucchini Casserole a try; I’m confident you’ll be delighted with the results!

Frequently Asked Questions:

Can I make this casserole ahead of time?

Absolutely! You can assemble the entire Ground Beef Zucchini Casserole up to 24 hours in advance. Cover it tightly with plastic wrap and refrigerate. When you’re ready to bake, simply remove the plastic wrap and bake as directed, adding a few extra minutes to the cooking time to ensure it’s heated through. You might also want to cover it with foil for the first half of baking to prevent the top from browning too quickly.

What kind of ground beef is best for this recipe?

For this casserole, I recommend using 80/20 ground beef. This ratio provides a good balance of flavor and moisture without being overly greasy. If you prefer a leaner option, 90/10 ground beef will also work, but you might need to add a splash more liquid or a little extra fat (like olive oil) when sautéing the vegetables to prevent dryness.
