Description
This cheesy Ground Beef Zucchini Casserole is a hearty, low-carb dinner packed with savory beef, tender zucchini, and melted mozzarella. It’s quick to prep, easy to bake, and perfect for busy weeknights or meal prep days.
Ingredients
2 medium zucchini (about 2 lbs), sliced into ½″ rounds
1 tbsp olive oil
1 small onion, finely diced
2 garlic cloves, minced
1 lb lean ground beef
2 tsp Italian seasoning
½ tsp kosher salt (plus more for salting zucchini)
½ tsp black pepper
1 (28 oz) can diced tomatoes, drained
2 cups shredded mozzarella cheese
Instructions
Place zucchini slices in a colander, sprinkle with salt, toss, and let sit 15 minutes.
Rinse and pat dry thoroughly.
In a skillet, sauté onion in olive oil over medium-high heat for 2 minutes.
Add garlic and ground beef. Cook until browned.
Stir in tomatoes, seasoning, salt, and pepper. Remove from heat.
Preheat oven to 350°F. In an 8×8 baking dish, layer half of the beef, zucchini, and cheese. Repeat layers.
Bake for 20–25 minutes until cheese is golden.
Let rest 10 minutes before serving.
Notes
Salting the zucchini helps prevent a watery casserole. For deeper layers, use an 8×8 pan. Assemble right before baking for best texture. Do not freeze.
