2 tablespoons pure maple syrup or brown sugar

👩🍳 Step-by-Step Preparation Instructions
-
Preheat and Prepare: Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch glass baking dish or roasting pan with olive oil or butter.
-
Arrange the Vegetables: Slice the sweet potatoes, Yukon gold potatoes, and carrots into even, thin rounds. Arrange them tightly in alternating rows or concentric patterns inside the baking dish so they stand slightly angled.
-
Add Cranberries & Herbs: Scatter the fresh cranberries evenly in between the vegetable slices. Sprinkle the minced garlic, fresh thyme, and chopped rosemary all over the top.
-
Make the Glaze: In a small bowl, whisk together the olive oil, maple syrup, sea salt, and black pepper. Drizzle this flavorful mixture evenly over the entire gratin, ensuring all the vegetable slices get lightly coated.
-
Bake: Cover the dish loosely with aluminum foil and bake for 30 minutes to ensure the vegetables steam and soften. Remove the foil and bake for an additional 25 to 35 minutes, or until the vegetables are fork-tender and the edges are caramelized and golden brown.
-
Garnish and Serve: Garnish with fresh rosemary sprigs and extra thyme leaves. Serve warm straight from the baking dish!

❓ Frequently Asked Questions (High-CPC Query Insights)
1. Can I prepare this root vegetable gratin ahead of time?
Yes. You can slice and arrange the vegetables in the baking dish a few hours in advance. Cover it tightly with plastic wrap and store it in the refrigerator. When you are ready to bake, bring it to room temperature, drizzle with the oil-maple mixture, and bake as directed.
2. What other vegetables work well in this gratin?
You can easily customize this dish by adding sliced parsnips, butternut squash, or golden beets alongside the potatoes and carrots for an even deeper, earthy flavor profile.
3. How do I ensure the potatoes and carrots cook evenly?
The secret to even cooking is consistency. Try to slice your potatoes, sweet potatoes, and carrots to a uniform thickness (about 1/4 inch thick). Covering the dish with foil for the first half of the baking time ensures the vegetables soften completely before the edges brown and caramelize.
