Step-by-Step Directions for Root Vegetable Gratin with Sweet Potatoes, Parsnips, and Beets
Preheat the Oven: Start by preheating your oven to 400°F (200°C). Grease a 3-quart baking dish with the softened butter.
Prepare the Vegetables: Slice the sweet potatoes, parsnips, and beets into thin, even rounds to ensure an even cook.
Coat the Vegetables: In separate bowls, coat the sliced sweet potatoes and parsnips with 4 tablespoons of cream each, while coating the beet slices with 2 tablespoons of cream. Mix in half of the Parmesan cheese and half of the chopped thyme for flavor, and season with salt and pepper according to your taste.
Create the Base Layer: Pour 1/4 cup of cream into the greased baking dish, followed by a sprinkling of 1/2 ounce of Parmesan cheese and the minced garlic.
Layer the Vegetables: Begin layering the vegetables upright in the dish, alternating between sweet potatoes, parsnips, and beets to create a visually appealing pattern.
Season and Cover: After layering, season once more with salt and pepper. Top the layered vegetables with the remaining Parmesan cheese, cover the dish with foil, and bake in the preheated oven for 30 minutes.
Finish Baking: Remove the foil and sprinkle Gruyère cheese over the top. Bake uncovered for another 18–20 minutes, or until the cheese is golden and bubbling.
Garnish and Serve: Once out of the oven, garnish your gratin with fresh thyme and serve warm, allowing everyone to enjoy a slice of this comforting dish.
