Step‑by‑Step Instructions for Ground Beef Zucchini Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This step is crucial for achieving that bubbly, golden topping as your Ground Beef Zucchini Casserole bakes. While the oven heats up, you can prepare your vegetables and other ingredients, ensuring everything is ready to go when it’s time to assemble the dish.
Step 2: Prepare the Zucchini
Slice the zucchini into ½-inch rounds, then sprinkle them with salt and place them in a colander for 15 minutes. This salting step helps draw out excess moisture, preventing a soggy casserole. After 15 minutes, rinse the zucchini well and pat dry with a paper towel, removing any released water. This ensures the best texture in your casserole.
Step 3: Sauté the Onion
Heat a drizzle of olive oil in a skillet over medium-high heat, then add the diced onion. Sauté for about 2 minutes, until the onion becomes translucent and fragrant. Stir frequently to prevent burning and to develop that lovely, sweet flavor that will form the base of your Ground Beef Zucchini Casserole.
Step 4: Cook the Ground Beef
Add the minced garlic and the ground beef to the skillet with the onions. Cook for about 5 minutes, breaking up the meat with a spoon until it’s browned and no longer pink. Look for the beef to reach an even brown color; this step enhances the flavor and gives a hearty base to your casserole.
Step 5: Mix in Tomatoes and Seasoning
Stir in the diced tomatoes, Italian seasoning, kosher salt, and pepper to the beef mixture. Allow it to simmer for 1 minute, letting all those robust flavors meld together. You should see the mixture become fragrant and slightly thicker, which adds depth to your Ground Beef Zucchini Casserole.
Step 6: Layer the Casserole
In an 8×8 baking dish, spread half of the beef mixture on the bottom. Then layer half of the salted zucchini rounds over the beef. Sprinkle half of the mozzarella cheese on top, creating a lovely base. Repeat the layering process with the remaining beef mixture, zucchini, and top with the rest of the cheese for that melty finish.
Step 7: Bake the Casserole
Place the assembled Ground Beef Zucchini Casserole in the preheated oven and bake for 20–25 minutes. Keep an eye out for that beautiful golden and bubbly cheese on top. The casserole should be hot throughout and firm enough to hold its shape when served.
Step 8: Rest Before Serving
Once baked, remove the casserole from the oven and allow it to rest for 10 minutes before slicing. This resting period helps the layers set, making it easier to serve and enhancing the overall flavor. When you slice into it, you’ll see the perfect blend of the tender zucchini and flavorful ground beef!
