Simple Scalloped Potatoes
Ingredients
Equipment
Method
- Preheat your oven to 350°F and grease a 9x13-inch baking dish with butter or cooking spray.
- Prepare the potatoes: Wash, peel, and slice the potatoes into uniform ⅛-inch thick rounds. Place sliced potatoes in cold water to prevent browning while preparing the sauce.
- Make the cream sauce: In a large saucepan, melt butter over medium-low heat. Add diced onion and minced garlic, cooking for 3-4 minutes until the onion begins to soften and becomes fragrant.
- Create the roux: Sprinkle flour over the butter mixture and cook for 2 minutes, stirring constantly to eliminate the raw flour taste and create a smooth paste.
- Add liquids gradually: Combine milk and broth in a measuring cup. Slowly add the liquid mixture to the flour base, whisking continuously to prevent lumps. Start with small amounts and whisk until smooth before adding more liquid.
- Season and thicken: Once all liquid is incorporated, increase heat to medium and bring the mixture to a boil while whisking constantly. Add ½ teaspoon salt, ⅛ teaspoon pepper, and thyme if using. Let the sauce boil for 1 minute until thickened.
- Layer the potatoes: Drain the potato slices and pat dry with paper towels. Layer ⅓ of the potatoes in the prepared baking dish, seasoning with ¼ teaspoon salt and ⅛ teaspoon pepper. Pour ⅓ of the cream sauce evenly over the potatoes.
- Repeat layers: Continue layering the remaining potatoes and sauce, seasoning each potato layer with salt and pepper. End with the final portion of cream sauce covering the top layer completely.
- Bake covered: Cover tightly with aluminum foil and bake for 45 minutes. Remove the foil and continue baking for 35-45 minutes until the top is golden brown and potatoes are fork-tender.
- Rest and serve: Allow the scalloped potatoes to rest for 20 minutes before serving to let the sauce thicken properly. Garnish with fresh chives and serve while warm.
