This savory gratin highlights the hearty goodness of earthy root veggies—like potatoes, carrots, and parsnips—topped with a golden, bubbling crust that’s guaranteed to have everyone heading back for seconds.
Ingredients
- 2 large russet potatoes, peeled and thinly sliced
- 2 large carrots, peeled and thinly sliced
- 2 parsnips, peeled and thinly sliced
- 2 tablespoons unsalted butter
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 cup heavy cream
- 1½ cups shredded sharp cheddar cheese
- 2 tablespoons chopped fresh herbs (such as rosemary, thyme, or a mix)
- Salt and freshly ground black pepper, to taste
Instructions
Preheat your oven to 375°F (190°C) and lightly butter a medium-sized baking dish. Begin by heating the butter in a skillet over medium heat. Add the chopped onion and cook until translucent, about five minutes. Stir in the minced garlic and let it cook for another minute or so, just until fragrant.
Next, remove the skillet from the heat and stir the heavy cream into the onion-garlic mixture, sprinkling in a pinch of salt and pepper. At this point, arrange half of your sliced potatoes, carrots, and parsnips in the baking dish, layering them evenly. Pour half of the cream mixture over the vegetables, then sprinkle on half of the cheddar cheese and fresh herbs. Repeat with the remaining vegetable slices, cream mixture, and cheese on top.
Cover the dish with foil and bake for 25 minutes. Then, remove the foil and continue baking for another 15–20 minutes, or until the cheese is golden and bubbly, and the vegetables are tender when pierced with a fork. Let the gratin rest for about 10 minutes so that it’s easier to slice into neat portions.
This comforting winter casserole is perfect for Sunday suppers, holiday gatherings, or whenever you crave hearty, warming flavors. If you’re mindful of dietary restrictions, you can opt for a lower-fat cream or a plant-based alternative, and even dairy-free cheese can work well in this gratin. Add red bell peppers or sweet potatoes for a pop of color and extra nutrients, or swap in your favorite blend of herbs to match your taste. With its luscious layers and irresistible aroma, this Rustic Cheddar & Herb Root Vegetable Gratin is sure to be a new favorite in your recipe rotation.
