Ingredients
Main Ingredients:
1 lb Ground beef
2 medium Zucchinis, sliced into rounds or half-moons
1 small Yellow onion, chopped
2 cloves Garlic, minced
1 cup Shredded cheddar cheese (or a cheddar-mozzarella blend)
1/2 cup Tomato sauce or crushed canned tomatoes
1/2 cup Sour cream or heavy cream (for richness)
Seasonings:
1 tsp Italian seasoning
1/2 tsp Garlic powder
1/2 tsp Salt
1/4 tsp Black pepper
2 tbsp Chopped fresh parsley (for garnish)
Step-by-Step Instructions
Step 1: Prep Zucchini & Preheat Oven
1. Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
2. Slice the zucchinis into 1/4-inch thick rounds. Sprinkle lightly with a pinch of salt and lay them on paper towels for 10 minutes to draw out excess moisture, then pat dry.
Step 2: Brown the Meat
1. Heat a large skillet over medium-high heat. Add the ground beef and chopped onion. Cook for 6 to 8 minutes until the beef is browned and onions are soft. Drain any excess grease.
2. Stir in the minced garlic, Italian seasoning, garlic powder, salt, pepper, and tomato sauce. Simmer for 2 to 3 minutes, then stir in the sour cream until smooth.
Step 3: Layer & Bake
1. Arrange half of the sliced zucchinis in an even layer at the bottom of the prepared baking dish.
2. Spoon the cooked ground beef mixture over the zucchini layer.
3. Layer the remaining zucchini slices over the meat, then sprinkle the shredded cheddar cheese evenly across the top.
4. Bake uncovered for 25 to 30 minutes until the zucchini is tender and the cheese is melted and golden brown.
5. Let rest for 5 to 10 minutes before slicing. Garnish with fresh chopped parsley and serve warm!
Chef’s Tips
Prevent Wateriness: Zucchini has a high water content. Salting and patting the slices dry before baking ensures your casserole sauce stays thick and creamy rather than watery.
