These components come together to create a dish that feels both wholesome and indulgent.

- 1/2 cup tomato sauce (optional, for added flavor): Brings a subtle tang and moisture to enhance taste complexity.

- 1/4 teaspoon red pepper flakes (optional, for heat): Offers a gentle kick to balance the richness if you’re feeling adventurous.

How to Make Cheesy Beef & Zucchini Casserole Recipe
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). Setting the right temperature upfront ensures your casserole bakes evenly into a bubbling, golden-cheesy masterpiece.
Step 2: Cook the Ground Beef
Heat a splash of olive oil in a large skillet over medium heat. Add the ground beef, breaking it up with a spoon as it cooks until it turns deliciously browned and fully cooked through. Don’t forget to drain any excess fat — this keeps the dish from becoming greasy while keeping the beef juicy.
Step 3: Sauté the Vegetables
Next, toss in the chopped onion and minced garlic with the beef. Let them cook for 2-3 minutes until softened and fragrant. Then, add the sliced zucchini alongside oregano, basil, red pepper flakes if using, and a generous pinch of salt and pepper. Sauté everything together for another 5-7 minutes until the zucchini softens but still holds its shape, adding a delightful bite.
Step 4: Combine the Ingredients
Pour in the heavy cream and optional tomato sauce, stirring constantly to combine into a creamy, flavorful mixture. Let it simmer gently for 2-3 minutes so all the herbs and spices meld into a cohesive sauce. Taste and adjust seasoning as needed — this is where the magic flavor balance happens.
Step 5: Layer the Casserole
Transfer the savory beef and zucchini mixture to a greased 9×13-inch baking dish, spreading it out evenly. Then come the cheeses: sprinkle shredded mozzarella and sharp cheddar on top. This cheesy layer will melt into a golden crust that’s pure comfort food bliss.
Step 6: Bake the Casserole
Slide the dish into the preheated oven and bake for 15-20 minutes, or until the cheese is fully melted, bubbly, and turning golden brown in spots. Your kitchen will fill with an irresistible aroma hinting at what’s to come.
Step 7: Serve and Enjoy
Once out of the oven, let the casserole rest for a few minutes to settle. This serves to lock in the flavors and makes scooping easier. Then dig in and savor every cheesy, savory bite of your delightful creation.
