A quick and comforting scalloped potatoes recipe featuring a simple, creamy sauce made with just five ingredients. Perfect for weeknight dinners or holiday potlucks.

Ingredients

Scale
  • 3 pounds Yukon Gold or Russet potatoes, peeled and thinly sliced
  • 4 tablespoons unsalted butter, softened
  • 3 tablespoons all-purpose flour
  • 2 cups whole milk
  • 2 cloves garlic, minced
  • 1 teaspoon salt
  • 1/2 teaspoon freshly ground black pepper
  • Optional: 1/2 cup grated sharp cheddar or Gruyère cheese

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. Peel and slice potatoes thinly, about 1/8 inch thick.
  3. In a medium saucepan, melt butter over medium heat. Add minced garlic and sauté for about 1 minute until fragrant.
  4. Whisk in flour and cook for about 2 minutes, stirring constantly.
  5. Gradually add milk while whisking continuously. Cook and whisk until sauce thickens, about 5 minutes.
  6. Stir in salt and black pepper; adjust seasoning to taste.
  7. Lightly butter a 9×13 inch baking dish. Layer sliced potatoes evenly, pour some sauce over, and repeat layers, finishing with sauce on top.
  8. If using cheese, sprinkle half during layering and save the rest for the top.
  9. Cover the dish with aluminum foil and bake for 45 minutes.
  10. Remove foil and bake uncovered for an additional 20-25 minutes until top is golden and potatoes are tender.
  11. Remove from oven and let rest for 10 minutes before serving.

Notes

If sauce is too thick before baking, whisk in a splash more milk. If too thin, cook longer on stove. Cover with foil during baking to prevent drying out. Let dish rest 10 minutes before serving for easier slicing. For gluten-free, substitute flour with cornstarch or gluten-free flour blend. Optional cheese adds richness.
