Description
Cheesy Scalloped Potatoes are a classic comfort food side dish made with thinly sliced russet potatoes, sweet onions, and a rich cheddar cheese sauce. Baked until bubbling and golden, this dish is creamy, hearty, and the perfect addition to any meal—whether for a holiday table or cozy family dinner.
Ingredients
4 russet potatoes (about 2 lbs), peeled and sliced 1/4 inch thick
1 yellow onion, sliced into rings
3 tbsp unsalted butter
3 tbsp all-purpose flour
1/2 tsp kosher salt
2 cups whole milk, room temperature
1 1/2 cups shredded mild cheddar cheese
Salt and pepper to taste
Instructions
Preheat oven to 400°F. Grease an 8×8-inch or 2-quart baking dish.
Layer half the potatoes and onion rings in the dish, then repeat with remaining half.
In a saucepan, melt butter over medium heat. Whisk in flour and salt; cook 1 minute.
Slowly whisk in milk. Cook until thick and smooth, stirring frequently.
Add cheddar cheese and stir until melted and creamy.
Pour cheese sauce evenly over potatoes and onions.
Cover with foil and bake 85–90 minutes until potatoes are tender.
Broil uncovered for 2–4 minutes for a golden top.
Let rest 5–10 minutes before serving. Add salt and pepper to taste.
Notes
Slice potatoes evenly for consistent texture.
Room temp milk prevents curdling and blends better.
Assemble a few hours ahead and refrigerate until baking.
Try Gruyère or sharp cheddar for deeper flavor.
Store leftovers in the fridge up to 4 days.
