Step-by-Step: How to Make Ground Beef Zucchini Casserole
1. Prepare the Zucchini
Preheat oven to 375°F (190°C). Slice zucchini into thin rounds and set aside.
2. Cook the Beef
In a skillet over medium heat, add olive oil and sauté onions until soft. Add garlic, then ground beef. Cook until beef is browned, breaking it up as it cooks. Drain excess fat if needed. Season with salt, pepper, Italian seasoning, and red pepper flakes. Stir in tomato sauce and simmer for 2–3 minutes.
3. Assemble the Casserole
In a greased baking dish, layer half of the zucchini rounds. Spread half of the beef mixture over the zucchini. Sprinkle with half the mozzarella and Parmesan. Repeat layers with remaining zucchini, beef, and cheeses.
4. Bake
Cover with foil and bake for 20 minutes. Remove foil and bake another 10–15 minutes, until cheese is bubbly and golden.
5. Serve
Let stand 5 minutes before slicing and serving. Garnish with fresh herbs if desired.
Tips for Perfect Breakfast Casserole With Zucchini or Dinner Every Time
- Salt and blot zucchini rounds to remove excess moisture and prevent sogginess.
- Use lean ground beef to keep it light.
- For a breakfast version, crack 4–6 eggs over the casserole before baking.
- Add fresh basil or parsley for a pop of freshness.
Common Mistakes to Avoid When Making Ground Meat And Zucchini Recipes
🚫 Not draining excess liquid — zucchini releases water as it cooks, so salt it ahead of time.
🚫 Using high-fat beef — can make the dish greasy.
🚫 Overbaking — can dry out the beef and overcook the zucchini.
