How to Make Creamy Winter Vegetable Casserole

Step 1: Preheat your oven to 400°F. Toss diced potatoes, carrots, and parsnips with olive oil, salt, pepper, and thyme. Spread them on a baking sheet and roast for 25 minutes until tender and just starting to brown.
Step 2: In a large skillet over medium heat, cook diced onions and garlic in olive oil until translucent. Stir in flour and cook for 1 minute. Gradually whisk in the broth, milk, and cream. Bring to a gentle simmer, stirring constantly, until the sauce thickens. Stir in half the shredded Gruyère until melted.
Step 3: Lower the oven to 375°F. In a casserole dish, combine the roasted vegetables and spinach or kale. Pour the creamy sauce over and gently mix. Top with the remaining cheese. Bake uncovered for 20-25 minutes until bubbly and golden on top.
