How to Make Cheesy Beef & Zucchini Casserole
Step 1: Preheat Your Oven
Start by preheating your oven to 375°F (190°C). This ensures that your casserole bakes evenly and comes out perfectly bubbly and golden.
Step 2: Sauté Aromatics
In a large skillet, heat up olive oil over medium heat. Add the chopped onion and minced garlic, sautéing them until the onion turns translucent—about 2-3 minutes. This step brings out their natural sweetness and lays a flavorful foundation for your casserole.
Step 3: Brown the Beef
Next, add the ground beef to the skillet. Break it apart with your spatula as it cooks until it’s nicely browned—this should take about 5-7 minutes. If there’s any excess fat after browning, feel free to drain it off. This keeps the dish from becoming greasy!
Step 4: Combine Vegetables and Seasoning
Once your beef is cooked through, stir in the sliced zucchini along with the drained diced tomatoes. Sprinkle in Italian seasoning, salt, and pepper. Cook everything together for another 5 minutes; this helps soften the zucchini while allowing those flavors to blend beautifully.
Step 5: Assemble in Baking Dish
Now it’s time to transfer that savory mixture into a greased 9×13-inch baking dish. Spread it out evenly so every bite will be flavorful.
Step 6: Cheese It Up!
Sprinkle shredded cheddar and mozzarella cheese generously over the top of your casserole. If you’re feeling adventurous and want an added crunch, toss on some breadcrumbs before baking.
Step 7: Bake Away!
Pop your dish into the preheated oven and bake for about 25-30 minutes. Keep an eye out until that cheese is bubbling and golden brown—it’s hard not to sneak a peek because it smells so good!
Step 8: Serve and Enjoy!
Let your casserole cool slightly once it’s out of the oven—this helps set everything together nicely. Then serve up generous portions! Enjoy every cheesy bite with friends or family around the table; this dish was made for sharing!
Pro Tips for Making Cheesy Beef & Zucchini Casserole
Creating a delicious Cheesy Beef & Zucchini Casserole is a breeze with these handy tips!
- Use fresh ingredients: Fresh zucchini and quality ground beef enhance the flavor and texture of your casserole, making every bite delightful.
- Don’t overcook the zucchini: Cooking the zucchini just until slightly tender ensures it retains some bite and doesn’t become mushy when baked.
- Experiment with cheese: While cheddar and mozzarella are classic choices, feel free to mix in other types of cheese like pepper jack for a spicy kick or gouda for a smoky flavor.
- Make it ahead of time: Prepare the casserole the night before and store it in the refrigerator. This allows the flavors to meld, and all you need to do is pop it in the oven when you’re ready to eat!
- Adjust seasoning to taste: Everyone’s palate is different! Taste as you go and adjust salt, pepper, or Italian seasoning to suit your preference.
