Serves: 6 servings
Ingredients
- 4 medium sweet potatoes
- 1 cup low-fat milk
- 1 cup shredded cheese
- 2 cloves garlic, minced
- Salt and pepper to taste
- 1 tsp thyme
Instructions
- Preheat the oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish with olive oil or cooking spray to prevent sticking.
- Wash sweet potatoes thoroughly and peel them. Using a sharp mandoline or knife, slice the sweet potatoes into thin, uniform rounds approximately 1/8 inch thick. This ensures even cooking and consistent texture.
- In a medium mixing bowl, combine low-fat milk, minced garlic, thyme, salt, and pepper. Whisk the ingredients together until well incorporated, creating a flavorful base for the gratin.
- Layer the sweet potato slices in the prepared baking dish, slightly overlapping each slice. After each layer, sprinkle a portion of shredded cheese and drizzle some of the milk mixture.
- Continue layering sweet potatoes, cheese, and milk mixture until all ingredients are used. The top layer should be covered with cheese for a golden, crispy finish.
- Cover the baking dish with aluminum foil, ensuring it's not touching the cheese. This helps prevent excessive browning and allows even cooking.
- Place the covered dish in the preheated oven and bake for 35 minutes. Then remove the foil and continue baking for an additional 15 minutes until the top is golden brown and potatoes are tender.
- Remove from oven and let the gratin rest for 10 minutes. This allows the dish to set and makes serving easier. The resting period helps absorb remaining liquid and intensifies flavors.
- Serve hot as a side dish, garnishing with fresh thyme or chopped parsley if desired. The gratin pairs wonderfully with roasted chicken or grilled fish.
Tips
- Slice Consistency is Key: Use a mandoline or a sharp knife to create uniform 1/8-inch thick sweet potato rounds. This ensures even cooking and a professional-looking dish.
- Layer Like a Pro: Don't just dump ingredients – create beautiful, slightly overlapping layers of sweet potato slices, alternating with cheese and milk mixture for maximum flavor distribution.
- Foil Technique: Cover the dish initially to prevent over-browning, then uncover for the last 15 minutes to achieve that perfect golden, crispy top.
- Cheese Selection Matters: While the recipe calls for shredded cheese, experiment with different varieties like Gruyère for a more complex flavor, or a mix of cheeses for depth.
- Resting is Crucial: Always let the gratin rest for 10 minutes after cooking. This allows the dish to set and helps the flavors meld together beautifully.
- Make-Ahead Magic: This dish can be prepared in advance and refrigerated, then baked just before serving – perfect for meal prep or entertaining!
