How to Make Cheesy Beef & Zucchini Casserole

Now that you have all your ingredients ready, let’s embark on this cooking journey step by step:
- Step 1: Preheat Your Oven: Set your oven to 375°F (190°C) so it’s hot and ready to bake the casserole.
- Step 2: Brown the Ground Beef: In a large skillet, heat some olive oil over medium heat. Add the ground beef, breaking it apart with a spoon. Cook until fully browned. Drain any excess fat to keep the dish light.
- Step 3: Sauté the Aromatics: Add the chopped onion and minced garlic to the skillet. Cook for 2-3 minutes until the onion softens and releases its aromatic essence.
- Step 4: Add Zucchini and Seasonings: Stir in the sliced zucchini along with oregano, basil, red pepper flakes, salt, and pepper. Sauté for 5-7 minutes until the zucchini is tender but still has a bite.
- Step 5: Mix in Cream and Tomato Sauce: Pour in the heavy cream and optional tomato sauce. Let the mixture simmer gently for about 2-3 minutes to meld the flavors. Adjust seasoning to taste.
- Step 6: Assemble the Casserole: Transfer the beef and zucchini mixture evenly into a greased 9×13-inch baking dish. Sprinkle the mozzarella and cheddar cheeses evenly over the top.
- Step 7: Bake to Perfection: Place the baking dish in the preheated oven and bake for 15-20 minutes, or until the cheese is melted, bubbly, and slightly golden.
- Step 8: Let It Cool and Serve: Once baked, remove the casserole from the oven and let it cool for a few minutes. Serve warm and enjoy the explosion of flavors!
