Step‑by‑Step Instructions for Creamy Winter Vegetable Casserole
Step 1: Prepare the Vegetables
Begin by peeling and chopping the cauliflower, broccoli, carrots, parsnips, and potatoes into uniform bite-sized pieces to ensure even cooking. In a large pot, steam or parboil the carrots, parsnips, and potatoes for about 5–7 minutes until just tender. This pre-cooking will help them meld perfectly into the creamy winter vegetable casserole.
Step 2: Make the Cheese Sauce
In a medium saucepan, melt 3 tablespoons of butter over medium heat, then sauté the chopped onion and minced garlic for 3–4 minutes until they are softened and fragrant. Stir in 3 tablespoons of flour to create a roux, cooking for another minute before gradually whisking in 2 cups of milk. Allow the mixture to thicken for about 5–7 minutes, then stir in 2 cups of cheddar cheese, ¼ cup of parmesan, salt, pepper, and a pinch of nutmeg until the sauce is smooth and creamy.
Step 3: Combine Ingredients for Baking
Preheat your oven to 375°F (190°C) while you prepare the baking dish. In a large mixing bowl, combine the steamed vegetables with the prepared cheese sauce, tossing gently until everything is fully coated and well combined. Transfer the mixture into a greased baking dish, ensuring it’s evenly spread out for consistent cooking.
Step 4: Add Topping and Bake
For the finishing touch, sprinkle breadcrumbs and any remaining cheese over the top of the casserole. This will create a delightful crispy layer once baked. Place the dish in the preheated oven and bake uncovered for 30–35 minutes until the top is golden and bubbly. The aroma will fill your kitchen, promising a cozy meal ahead.
Step 5: Let it Rest Before Serving
After removing the creamy winter vegetable casserole from the oven, let it sit for about 5–10 minutes to set. This step is essential as it allows the flavors to meld together beautifully. Serve warm and watch as your family enjoys every comforting bite!

Creamy Winter Vegetable Casserole Recipe FAQs
How do I choose the best vegetables for this casserole?
