  • 1 tbsp olive oil
  • 1/2 tsp Salt
  • 1/4 tsp Black pepper
For the Cream Sauce
  • 4 tbsp unsalted butter
  • 1/4 cup all-purpose flour
  • 2 cups whole milk warmed
  • 1/2 cup vegetable broth
  • 1 cup shredded Gruyere cheese or sharp cheddar
  • 1/4 tsp ground nutmeg
  • 1 tsp dried thyme
  • to taste Salt and black pepper
For the Crispy Topping
  • 1/2 cup panko breadcrumbs
  • 1/4 cup grated Parmesan cheese
  • 2 tbsp unsalted butter melted

Equipment

  • Large Pot
  • Cutting board
  • Sharp knife
  • 9×13 inch baking dish
  • Large Skillet or Dutch Oven
  • Whisk
  • Large mixing bowl

Method
 

Preparation
  1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish and set aside.
Prepare the Vegetables
  1. In a large pot of lightly salted boiling water, add the diced potatoes, sliced carrots, and sliced parsnips. Cook for 5-7 minutes, or until just tender-crisp. Drain well and set aside.
  2. While the root vegetables are par-cooking, heat 1 tablespoon of olive oil in a large skillet or Dutch oven over medium heat. Add the sliced leeks and halved Brussels sprouts. Sauté for 5-7 minutes, until the leeks are softened and the Brussels sprouts are slightly tender. Season with 1/2 tsp salt and 1/4 tsp black pepper. Remove from heat and set aside.
Make the Cream Sauce
  1. In the same skillet or Dutch oven (no need to clean), melt 4 tablespoons of unsalted butter over medium heat. Whisk in the all-purpose flour and cook for 1-2 minutes, stirring constantly, to create a roux. It should be light golden in color.
  2. Gradually whisk in the warmed whole milk, then the vegetable broth, ensuring no lumps form. Continue to whisk and cook for 5-7 minutes, until the sauce thickens and coats the back of a spoon. Reduce heat to low.
  3. Stir in the shredded Gruyere cheese until melted and smooth. Add the ground nutmeg, dried thyme, and season generously with salt and black pepper to taste. Remove from heat.
Assemble and Bake
  1. In a large mixing bowl, gently combine the par-cooked root vegetables and the sautéed leeks and Brussels sprouts. Pour the creamy cheese sauce over the vegetables and stir gently until everything is well coated.
  2. Transfer the vegetable mixture into the prepared 9×13 inch baking dish, spreading it evenly.
  3. In a small bowl, combine the panko breadcrumbs, grated Parmesan cheese, and 2 tablespoons of melted butter. Sprinkle this mixture evenly over the top of the casserole.
  4. Bake for 35-45 minutes, or until the casserole is bubbly around the edges and the topping is golden brown and crispy.
  5. Remove from the oven and let rest for 5-10 minutes before serving. This allows the sauce to set slightly and prevents it from being too runny.

Notes

This casserole is fantastic as a vegetarian main course or a hearty side dish. For a richer flavor, you can use half-and-half instead of whole milk. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated gently in the oven or microwave.

Pro Tips for Making This Creamy Winter Vegetable Casserole

Achieving that perfect, soul-warming Creamy Winter Vegetable Casserole isn’t just about following the steps; it’s about infusing it with a little extra love and know-how. Here are my go-to tricks for a casserole that truly shines.

First, when preparing your vegetables, ensure they are cut into roughly uniform sizes. This isn’t just for aesthetics; it guarantees they cook evenly, giving you that wonderful tender-crisp texture throughout our beloved casserole. Uneven pieces can lead to some being mushy while others are still firm.

My Secret Trick: For an extra layer of flavor in the cream sauce, I always sauté the leeks until they are incredibly soft and translucent before adding the flour. This caramelizes their natural sugars just slightly, adding an unparalleled depth that truly elevates this Creamy Winter Vegetable Casserole.

Don’t be shy with the seasoning! Taste your cream sauce before assembling. A good pinch of salt and fresh black pepper at this stage ensures every spoonful of the finished dish is perfectly balanced. Remember, root vegetables can absorb a lot of seasoning.

Finally, allow your casserole to rest for about 10-15 minutes after it comes out of the oven. This little pause allows the sauce to settle and thicken slightly, making for cleaner, more defined servings and preventing it from being too runny.

Fun Variations for Creamy Winter Vegetable Casserole

One of the greatest joys of home baking and cooking is the freedom to play and make a recipe truly your own! This Creamy Winter Vegetable Casserole is wonderfully adaptable, inviting all sorts of creative twists.

Herbaceous Twists

If you love a little extra garden freshness, consider adding a sprinkle of fresh rosemary or sage along with the dried thyme in your cream sauce. My sister always asks me to add a touch of fresh sage; she swears it makes the flavors sing even louder. These herbs complement the earthy vegetables beautifully.

Cheese, Please!

While Gruyere offers a wonderful nutty tang, feel free to experiment with other cheeses. A sharp cheddar can add a bolder, more familiar comfort, or a blend of provolone and mozzarella could give it a delightful stringy pull. A friend of mine loves when I swirl in a bit of smoked gouda for an extra layer of richness.

Add a Protein Boost

For a heartier meal, you could easily fold in some cooked, shredded chicken or diced ham into the vegetable mixture before adding the cream sauce. This transforms our delightful Creamy Winter Vegetable Casserole into a complete one-dish wonder, perfect for busy weeknights when you need something substantial.

What to Serve With Creamy Winter Vegetable Casserole

This Creamy Winter Vegetable Casserole is a heartwarming star all on its own, but it truly shines when paired with a few thoughtful accompaniments. Think of it as painting a complete picture on your dinner plate!

For a light and refreshing contrast, I love serving this rich casserole alongside a crisp, green salad with a simple vinaigrette. The bright acidity of the dressing cuts through the richness beautifully, making each bite of the casserole feel fresh. My mom always says a good salad cleanses the palate perfectly!

Another lovely pairing is a side of crusty, artisanal bread or a warm baguette. It’s perfect for soaking up every last bit of that luscious creamy sauce. A quick-serving idea is to simply warm up some store-bought focaccia, brushed with a little olive oil and sprinkled with sea salt.

If you’re looking to round out a more substantial meal, consider a simply roasted chicken or a pan-seared pork chop. The mild, savory flavors of these proteins complement the earthy vegetables without overpowering our wonderful Creamy Winter Vegetable Casserole.

How to Store Creamy Winter Vegetable Casserole

Ensuring your delicious Creamy Winter Vegetable Casserole stays fresh and delightful for days to come is key to enjoying your hard work! Proper storage means you can savor those cozy flavors long after dinner.

To store leftovers, first allow the casserole to cool completely to room temperature. Then, transfer it to an airtight container. It will keep beautifully in the refrigerator for up to 3-4 days. I always like storing casseroles in glass containers; they seem to keep everything tasting fresher and prevent any lingering fridge smells.

If you’ve made a larger batch, this casserole freezes quite well! Once cooled, divide it into freezer-safe containers or wrap individual portions tightly in foil and then place them in a freezer bag. It can be frozen for up to 2-3 months. When you’re ready to enjoy, thaw overnight in the refrigerator.

To reheat, either warm individual portions gently in the microwave or, for larger amounts, cover with foil and bake in a preheated oven at 350°F (175°C) until heated through, about 20-30 minutes. Remove the foil for the last few minutes if you want to crisp up the topping again.

Nutritional Benefits

This Creamy Winter Vegetable Casserole is a wonderful way to enjoy a medley of nutritious root vegetables, packing in essential vitamins and fiber. With hearty Yukon Gold potatoes, vitamin-rich carrots, and fiber-packed parsnips, it’s a treat that’s both satisfying and nourishing, embodying my approach of combining wholesome ingredients with comforting indulgence.
