Step‑by‑Step Instructions for Zucchini Hamburger Casserole

Step 1: Preheat Oven
Begin by preheating your oven to 375°F (190°C). While the oven heats, grease a 9×13-inch baking dish with a bit of olive oil or cooking spray. This will ensure that your Zucchini Hamburger Casserole doesn’t stick and comes out perfectly golden and bubbly.

Step 2: Prepare Zucchini
Slice the fresh zucchini into ¼-inch rounds and sprinkle a light layer of salt over the slices. Let them sit for about 10 minutes to draw out excess moisture. Once they’ve rested, pat the zucchini slices dry with a paper towel to prevent your casserole from becoming watery.

Step 3: Cook Beef Mixture
In a large skillet over medium heat, warm up a tablespoon of olive oil. Add the diced yellow onion and sauté until translucent, about 3-4 minutes. Toss in minced garlic and cook for an additional minute, then add the ground beef to the skillet. Cook until browned, making sure to break it apart with a spatula. Drain any excess fat.

Step 4: Add Tomato Ingredients
Stir in the crushed tomatoes, tomato paste, dried basil, oregano, and a pinch of red pepper flakes (if desired). Season with salt and pepper, then let the mixture simmer on low for about 5-7 minutes, allowing the flavors to meld beautifully together. Your savory sauce for the casserole is now ready.

Step 5: Assemble Casserole
In the prepared baking dish, layer half of the beef mixture at the bottom. Follow with half of the zucchini slices, stacking them evenly. Repeat the process, layering the remaining beef mixture and then topping it with the last of the zucchini. Finally, sprinkle a generous amount of mozzarella and Parmesan cheese over the top to create a comforting crust.

Step 6: Bake
Place your Zucchini Hamburger Casserole in the preheated oven and bake uncovered for 25-30 minutes. Look for the dish to become bubbly and the cheese to turn a delightful golden brown. If you prefer a crispy topping, turn on the broiler for an additional 2-3 minutes, keeping a close eye to prevent burning.

Step 7: Rest
Once baked, remove the casserole from the oven and allow it to rest for about 10 minutes. This resting period helps the layers settle, ensuring each slice holds together when served. Your Casserole is now ready to be sliced and enjoyed!

For even longer prep, you can freeze the unbaked casserole for up to 2 months—just remember to wrap it tightly in foil or plastic wrap to prevent freezer burn. When you’re ready to bake, simply thaw overnight if frozen, and cook as directed, adding a few extra minutes if baking from frozen.

Zucchini Hamburger Casserole Recipe FAQs
