Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 3 lbs Yukon Gold potatoes, washed and sliced about 1/4 inch thick
• 1/4 cup butter
• 1 cup onion, thinly sliced
• 4 cloves garlic, minced
• 1/4 cup all-purpose flour
• 2 cups milk (2% preferred)
• 1 cup chicken broth
• 1 tablespoon fresh thyme, minced
• 2 teaspoons salt
• 1 teaspoon black pepper
• 2 cups sharp cheddar cheese, shredded
• 1/2 cup Parmesan cheese, shredded

Directions

1. Preheat the oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish.
2. Prepare the potatoes: Slice the Yukon Gold potatoes thinly—about 1/4 inch thick—and layer half of them in the prepared dish. Season lightly with salt and pepper.
3. Make the sauce: In a large skillet, melt the butter over medium heat. Add the onions and garlic, and sauté for 3–5 minutes until fragrant and softened.
4. Whisk in the flour and cook for about 1 minute to create a roux. Gradually add the milk and chicken broth while whisking to prevent lumps.
5. Continue to whisk until the mixture thickens and becomes creamy. Season with thyme, salt, and black pepper.
6. Assemble: Pour half of the creamy sauce over the first layer of potatoes. Sprinkle half of the cheddar and parmesan cheese over the sauce. Repeat with the remaining potatoes, sauce, and cheese.
7. Bake: Cover tightly with foil and bake for 35 minutes. Remove the foil and bake uncovered for an additional 25 minutes until the top is golden and bubbly.
8. For a crispy finish, broil the top for 3–5 minutes.
9. Let the dish rest for at least 5 minutes before serving to allow the sauce to thicken.

FAQs

1. Can I slice the potatoes a day ahead?

Yes, but store them in cold water in the refrigerator to prevent browning.

2. Can I make this recipe ahead of time?

Absolutely. Bake the dish as directed, cool completely, then cover and refrigerate for up to 3 days. Reheat before serving.

3. Can I use russet potatoes instead of Yukon Gold?

Yes, russet potatoes work well but may need peeling due to their thicker skin.

4. Can I substitute dried thyme for fresh?

Yes, use 1 teaspoon of dried thyme in place of 1 tablespoon fresh.

5. How can I prevent the sauce from separating?

Whisk the sauce continuously and avoid overheating it before layering with the potatoes.

6. Can I add vegetables or protein?

Yes, sliced mushrooms, spinach, or cooked chicken can be layered for extra heartiness.

7. Why are my potatoes not soft enough after baking?

The slices may be too thick, or your oven may run cooler. Continue baking until tender.

8. What cheese melts best for scalloped potatoes?

Cheddar, gruyere, and fontina all melt beautifully for this type of dish.

9. Can I halve the recipe?

Yes, bake in an 8×8-inch pan and reduce the baking time slightly, checking for tenderness after 45 minutes.

10. Can I use nondairy milk?

Yes, unsweetened almond or oat milk can be used, though it may slightly alter the flavor and creaminess.
