Ground Beef Zucchini Bake is a comforting, low-carb casserole featuring layers of tender zucchini, seasoned ground beef, and melty cheese. It’s easy to make, full of flavor, and ideal for busy weeknights or meal prep.

Ingredients

  1. 1 lb ground beef
  2. 2 medium zucchinis, thinly sliced into rounds
  3. 1 small onion, chopped
  4. 2 cloves garlic, minced
  5. 1 can (14.5 oz) diced tomatoes, drained (or 1 cup tomato sauce)
  6. 1 ½ cups shredded mozzarella cheese
  7. ½ cup grated Parmesan cheese
  8. 2 tbsp olive oil
  9. 1 tsp salt
  10. ½ tsp black pepper
  11. 1 tsp dried oregano or Italian seasoning
  12. ¼ tsp red pepper flakes (optional)

Instructions

Preheat oven to 375°F (190°C) and grease a 9×13-inch baking dish.

  1. In a skillet, heat olive oil over medium heat. Add onion and garlic; sauté until soft.
  2. Add ground beef and cook until browned. Drain excess fat if needed.
  3. Stir in diced tomatoes or tomato sauce, oregano, salt, pepper, and red pepper flakes. Simmer for 5–7 minutes.
  4. Lightly salt the zucchini slices and pat dry to remove excess moisture.
  5. Layer half the zucchini slices in the bottom of the baking dish. Top with half the beef mixture and ½ cup mozzarella.
  6. Repeat layers with remaining zucchini, beef, and 1 cup mozzarella. Sprinkle Parmesan on top.
  7. Cover with foil and bake for 20 minutes. Remove foil and bake for another 15–20 minutes until bubbly and golden.
  8. Let rest for 5–10 minutes before serving.

Notes

  • Patting the zucchini dry helps prevent a watery casserole.
  • Use ground turkey or chicken for a leaner version.
  • Try different cheeses like cheddar or provolone for a new flavor twist.
  • This dish can be made ahead and refrigerated before baking.
  • Freeze leftovers in portions for quick meals.
