Step‑by‑Step Instructions for Cheesy Vegetable Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that when your Cheesy Vegetable Casserole is ready, it will bake evenly and achieve that perfectly golden, bubbly finish. While the oven warms, you can prepare your vegetables and cheese sauce, maximizing your cooking efficiency.
Step 2: Prepare the Vegetables
Blanch or lightly steam your chosen mixed vegetables until just tender, approximately 3–5 minutes. This prevents them from becoming soggy in your casserole. Once done, immediately transfer them to a bowl of ice water to stop the cooking process, and then drain thoroughly. This step helps keep your Cheesy Vegetable Casserole vibrant and textured.
Step 3: Make the Cheese Sauce
In a medium saucepan, melt 4 tablespoons of butter over medium heat, then whisk in ¼ cup of flour to create a roux. Cook this mixture for about 2 minutes until it turns golden. Gradually add in 2 cups of warm milk, stirring continuously for about 5 minutes, until it thickens. Remove from heat and stir in 2 cups of mixed shredded cheeses (like cheddar and mozzarella), along with your seasonings, until the cheese is fully melted and the sauce is creamy.
Step 4: Combine Ingredients
In a greased 9×13 inch casserole dish, layer your cooked vegetables and pour the creamy cheese sauce over them. Gently toss to ensure that each piece of vegetable is coated with the sauce. This step will guarantee that every bite of your Cheesy Vegetable Casserole is flavorful and delicious.
Step 5: Add Toppings
In a small bowl, combine ½ cup of breadcrumbs with 2 tablespoons of melted butter, then sprinkle this mixture over the top of the casserole. Follow with an additional ½ cup of shredded cheese for that irresistible crispy, cheesy crust. This topping will lend both flavor and texture, complementing the creamy layers underneath.
Step 6: Bake the Casserole
Place your casserole in the preheated oven and bake for 30 minutes, or until the top is golden brown and the cheese is bubbly. Keep an eye on it to avoid over-browning, and enjoy the enticing aroma wafting through your kitchen as it cooks. This is when your Cheesy Vegetable Casserole transforms into a comforting masterpiece.
Step 7: Let it Rest
Once you remove the casserole from the oven, let it cool for 10 minutes before slicing. This resting period allows the layers to meld beautifully and makes serving easier. It’s the perfect way to ensure you enjoy every delicious bite of your Cheesy Vegetable Casserole without it falling apart.
How to Store and Freeze Cheesy Vegetable Casserole
