Ingredients You Need to make Zucchini and Ground Beef Casserole
To make the bestย zucchini and ground beef skillet, hereโs what youโll need:
- 1lb ground beef
- ยฝ cup diced yellow onion
- 1 tablespoon minced garlic
- 2 teaspoons dried Italian seasoning
- 1 teaspoon salt
- ยฝ teaspoon ground black pepper
- 1-ยฝ lbs zucchini, sliced into ยผ" rounds and quartered
- 2 cans, 14.5 oz each, Italian style diced tomatoes

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.

Bake and Broil
