Step‑by‑Step Instructions for Ground Beef Zucchini Casserole
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This ensures that when you place your Ground Beef Zucchini Casserole in, it cooks evenly and develops that perfect golden-brown top. Set your oven timer while you prepare the ingredients, so everything runs smoothly!
Step 2: Prepare the Zucchini
Next, slice your zucchini into ½-inch rounds. Sprinkle kosher salt over them and place the slices in a colander to drain for 15 minutes. The salt will draw out excess moisture, preventing your casserole from becoming watery. After the time is up, rinse the zucchini slices under cold water and pat them dry with a clean towel.
Step 3: Sauté the Onion
In a large skillet over medium-high heat, add a splash of olive oil and sauté the diced onion for about 2 minutes until it becomes translucent and fragrant. This step is key for building flavor in your Ground Beef Zucchini Casserole. Stir occasionally to ensure even cooking and prevent burning.
Step 4: Cook the Beef and Garlic
Add in the minced garlic and ground beef to the skillet. Cook the mixture until the beef is well browned, approximately 5 minutes. Use a spatula to break up the beef, ensuring it cooks thoroughly. You’ll know it’s ready when the beef turns from pink to a hearty brown.
Step 5: Mix in the Tomatoes and Seasoning
Once the beef is browned, stir in the diced tomatoes, Italian seasoning, kosher salt, and black pepper. Allow the mixture to simmer for about 1 minute, stirring regularly to combine all the flavors. The tomatoes will create a delicious moisture base for your casserole, enhancing the overall taste.
Step 6: Layer the Casserole
In an 8×8-inch baking dish, spread half of the beef mixture as the first layer. Then, evenly distribute the zucchini slices over the beef. Follow with a layer of freshly shredded mozzarella cheese. Repeat with the remaining beef mixture, zucchini, and finish with a generous layer of mozzarella.
Step 7: Bake Until Golden
Place the assembled Ground Beef Zucchini Casserole into your preheated oven and bake for 20–25 minutes. You’ll know it’s done when the cheese is bubbly and golden brown on top, enticing everyone with its savory aroma.
Step 8: Rest Before Serving
Once it’s out of the oven, let the casserole rest for about 10 minutes. This resting period allows the layers to settle, making it easier to slice and serve. Enjoy this warm, comforting dish with family and friends!
