Escalloped Potatoes

Escalloped potatoes occupy a specific corner of the American comfort-food canon: thinly sliced spuds layered with a roux-thickened cheese sauce, baked until creamy and golden. This version leans into Velveeta for that smooth, never-broken cheese pull and adds green pepper and pimentos for color and a faint bell-pepper sweetness.

The roux is non-negotiable. Cooking the butter and flour together for a full minute before adding milk eliminates the raw-flour taste and creates a sauce that thickens evenly without lumps. Pour the milk in slowly while whisking constantly; a steady stream and aggressive whisk gives a glossy, smooth bechamel.

Velveeta is the right call here, surprisingly. The processed cheese contains emulsifiers that keep the sauce smooth through the long bake. Real cheddar can break and turn greasy after an hour-and-a-half in the oven. Tradition matters; this is what makes escalloped potatoes feel like escalloped potatoes.

Slice the potatoes thin and uniform, about ⅛ inch. A mandoline or food processor with a slicing blade does this fast and consistently. Uneven slices cook unevenly, leaving you with mush in some bites and undercooked potato in others.

The stirring midway through is a real tip from the original recipe. Turn the potatoes with a spoon at the one-hour mark so the sauce coats every layer and the top doesn’t dry out.

Pro Tips

• Russet or Yukon Gold both work; russets are starchier and more traditional.
• Cover with foil for the first hour to prevent the top from browning too fast.
• Test doneness by piercing potato slices with a knife; they should slide off easily.
• Let rest 10 minutes after baking; the sauce thickens beautifully as it sets.

Variations

• Add a layer of ham chunks between potato layers for a one-dish dinner.
• Stir in caramelized onions to the sauce for sweeter depth.
• Top with seasoned breadcrumbs in the last 15 minutes for a crunchy crust.
