How to Make Creamy Winter Vegetable Casserole

Prepare the Vegetables

Preheat oven to 375°F (190°C) and grease a 9×13-inch baking dish. Wash and chop vegetables into bite-sized pieces. Steam for 5–7 minutes until just tender.

Make the Cheese Sauce

In a saucepan, melt butter over medium heat. Stir in flour to create a roux and cook for 1–2 minutes. Gradually whisk in warm milk and cook until thickened, about 3–5 minutes. Stir in garlic powder, nutmeg, salt, pepper, cheddar, and Parmesan until smooth.

Combine & Bake

Place steamed vegetables in a large bowl and pour cheese sauce over them, gently combining. Transfer mixture to the prepared baking dish. Sprinkle breadcrumbs on top if using. Bake for 20–25 minutes until bubbly and golden. For a crispier topping, broil 2–3 minutes at the end.

Finish & Serve

Let the casserole rest for 5–10 minutes. Garnish with chopped parsley and serve warm.

Tips for Success

• Use warm milk to avoid lumps in the cheese sauce
• Steam vegetables just until tender-crisp; they will continue cooking in the oven
• For extra texture, add seasoned breadcrumbs or crushed crackers on top before baking
• Make ahead: Assemble in advance and refrigerate until ready to bake

Equipment Needed

• 9×13-inch baking dish
• Steamer or large pot with a steaming basket
• Medium saucepan for the cheese sauce
• Wooden spoon or whisk

Recipe Variations

• Gluten-Free: Use gluten-free flour and breadcrumbs
