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.
