How to Make Ground Beef and Zucchini Casserole

Step 1: Prepare the vegetables

Start by washing the zucchini and slicing them into thin rounds or half-moons for even cooking. Then, finely chop the onion and smash the garlic cloves to release their fragrant flavors.

Step 2: Brown the ground beef

Heat olive oil in a large skillet over medium heat, then add the ground beef. Cook until it’s fully browned, breaking it up with a spoon to ensure even crumbling. Drain excess fat if needed to keep the dish light.

Step 3: Sauté onions and garlic

Push the beef to one side of the skillet and add onions and garlic in the empty space. Cook until the onions become translucent and fragrant, about 3-4 minutes, mixing occasionally with the beef.

Step 4: Add zucchini and tomatoes

Mix in the sliced zucchini and canned diced tomatoes, along with Italian seasoning, salt, and pepper. Stir well to combine all ingredients and cook for 5-7 minutes until the zucchini softens but isn’t mushy.

Step 5: Assemble and bake

Transfer the mixture to a casserole dish and sprinkle shredded cheese evenly over the top. Bake at 375°F (190°C) for 20-25 minutes, or until the cheese is melted and bubbling with a golden crust.

Pro Tips for Making Ground Beef and Zucchini Casserole

• Drain excess fat: Removing fat from the cooked beef keeps the casserole from becoming greasy.
• Use fresh zucchini: Younger zucchini have milder flavor and less watery texture, enhancing the dish.
• Don’t overcook the zucchini: Slight firmness adds texture, so cook it just until tender before baking.
• Try a mix of cheeses: Combining mozzarella with sharp cheddar or parmesan enhances complexity.
• Season generously: Don’t be shy with herbs and spices to make every bite flavorful.

Creative Ways to Present
