Ingredients You Need to make Zucchini Ground Beef Casserole

To make the best zucchini ground beef skillet, here’s what you’ll need:

• 1lb ground beef
• ½ cup diced yellow onion
• 1 tablespoon minced garlic
• 2 teaspoons dried Italian seasoning
• 1 teaspoon salt
• ½ teaspoon ground black pepper
• 1-½ lbs zucchini, sliced into ¼" rounds and quartered
• 2 cans, 14.5 oz each, Italian style diced tomatoes
• 2 cups shredded mozzarella cheese

Step-by-Step Instructions

Brown the Meat

Add ground beef, onion and garlic to an oven proof skillet and heat over medium heat until beef is browned. Drain grease.

Spice It Up

Add Italian seasoning, salt and pepper and mix well.

Add The Veggies

Add zucchini and cook for 6-8 minutes or until tender.

Add Tomatoes and Cheese

Stir in tomatoes and top with cheese.

Bake and Broil

Bake at 350 degrees for 20-25 minutes or until cheese is melted and center is hot. Broil for 2-3 minutes if desired before serving. 

Broiling isn't necessary, but it really makes the casserole look incredible. Be careful and make sure your baking pan or ovenproof skillet can be broiled. I am using a 10" skillet.

This recipe will serve between six and eight people.

Serving Suggestions

This zucchini ground beef skillet pairs perfectly with a fresh side salad or some creamy mashed potatoes (or mashed cauliflower if you're low-carb). For extra fun, sprinkle grated parmesan (a.k.a. shaky cheese) on top—your kids (and inner child) will thank you!
