How to Make Zucchini Ground Beef Casserole

Step 1: Prepare Your Ingredients

Start by washing and slicing the zucchinis into thin rounds or half-moons for even cooking. Dice your onions and mince the garlic to have everything ready for the skillet.

Step 2: Brown the Ground Beef

Heat olive oil in a large skillet over medium heat. Add the ground beef, breaking it apart with a spatula, and cook until no longer pink. Drain any excess fat if necessary to keep the casserole light.

Step 3: Sauté Aromatics

Add onions and garlic to the browned beef, cooking until softened and fragrant, about 3 to 4 minutes. This step infuses the meat with rich flavor.

Step 4: Combine Zucchini and Tomatoes

Stir in sliced zucchini and diced canned tomatoes along with their juices. Season the mixture with salt, pepper, and Italian seasoning, then let it simmer until the zucchinis soften and the flavors meld, about 8 to 10 minutes.

Step 5: Assemble and Bake

Transfer the mixture into a baking dish, top with shredded cheese evenly, and bake in a preheated oven at 375°F (190°C) for 15 to 20 minutes, or until the cheese is gorgeous and bubbly.

Step 6: Rest and Serve

Let the casserole sit for 5 minutes post-bake to set up beautifully before serving. This helps it hold its shape and enhances every bite.

Pro Tips for Making Zucchini Ground Beef Casserole

• Drain Excess Liquid: If your zucchinis release too much water, drain some to avoid a soggy casserole.
• Use Fresh Ingredients: Fresh zucchini and seasonings make a noticeable difference in flavor.
• Don’t Overcook: Bake just until the cheese melts and bubbles to keep texture perfect.
• Layer Flavors: Sauté aromatics thoroughly for a deep, rich taste throughout the dish.
• Opt for Lean Beef: Leaner cuts prevent greasy results while delivering hearty satisfaction.
