🧄 Best Vegetables to Use for a Winter Casserole

Winter vegetables are sturdy. They hold up. They don’t turn to mush.

Top Picks (Mix & Match)

• Potatoes or sweet potatoes – creamy base

• Carrots – natural sweetness

• Parsnips – slightly nutty, very underrated

• Cauliflower – soaks up sauce beautifully

• Brussels sprouts – optional, but excellent when roasted first

• Leeks or onions – flavor builders

If your fridge looks chaotic… good. This recipe likes chaos.

🧀 The Creamy Sauce (Without Going Overboard)

Let’s talk about the star: the sauce.

I wanted something creamy but not nap-inducing. After a few experiments (and one slightly watery fail), this combo worked best.

Creamy Base Options

• Milk + a little butter + flour (classic)

• Half-and-half for extra richness

• Greek yogurt or sour cream for tang

• A handful of grated cheese (Gruyère or cheddar)

My personal favorite?
Milk + Greek yogurt + a bit of cheese. Creamy, balanced, not heavy.

🍲 Creamy Winter Vegetable Casserole Recipe

This is more of a guide than a strict recipe. Feel free to adjust.

Ingredients

• 3–4 cups mixed winter vegetables (chopped)

• 2 medium potatoes or sweet potatoes, thinly sliced

• 1 small onion or leek, sliced

• 2 tbsp butter or olive oil

• 2 tbsp flour

• 1½ cups milk

• ½ cup Greek yogurt or sour cream

• 1 cup shredded cheese (cheddar, Gruyère, or both)

• Salt, pepper, garlic powder

• Optional: thyme, rosemary, nutmeg

How to Make It

1. Preheat oven to 375°F (190°C).

2. Lightly roast firmer veggies (carrots, potatoes) for 15 minutes. This avoids soggy casserole sadness.

3. In a pan, melt butter, add flour, and cook 1 minute.

4. Slowly whisk in milk until smooth.

5. Stir in yogurt, cheese, and seasoning.

6. Layer vegetables in a baking dish. Pour sauce over.

7. Bake uncovered for 35–40 minutes until bubbly and golden.

Let it sit 10 minutes. It thickens. Patience pays off.
