Crispy Smashed Burgers with White Cheddar, Caramelized Onions and Old Bay Fries

These smashed burgers are all about texture-crispy, craggy edges achieved by pressing balls of beef flat in a hot pan. Topped with melted white cheddar, sweet caramelized onions and a tangy special sauce, they’re sandwiched in soft potato buns. On the side, crispy Old Bay fries complete the meal.

The special sauce, made with mayo, ketchup, Dijon and a hint of Old Bay, doubles as a dip for the fries. It’s a crowd-pleasing dinner that comes together in under an hour.

Instructions

1. Adjust rack to top position and preheat oven to 425°F. Wash and dry produce. Cut potatoes into ½-inch-thick wedges. Halve, peel and thinly slice onion.
2. Toss potatoes on a baking sheet with a drizzle of oil and half the Old Bay seasoning. Season lightly with salt and pepper. Roast on top rack until browned and crispy, 20-25 minutes.
3. While potatoes roast, heat a large drizzle of oil in a medium nonstick pan over medium-high heat. Add onion; cook, stirring occasionally, until browned and softened, 8-10 minutes. Add 1 tsp sugar and a splash of water; cook until caramelized and jammy, 2-3 minutes more. Season with salt and pepper. Transfer to a small bowl.
4. In another small bowl, combine mayonnaise, ketchup, mustard and remaining Old Bay seasoning to taste. Set aside. Form beef into two equal balls; season all over with salt and pepper.
5. Heat a drizzle of oil in the same pan over medium-high heat. Add beef balls. Firmly flatten each with a spatula to create very thin patties. Cook 3-4 minutes per side. In the last 1-2 minutes, top patties with cheddar; cover pan to melt cheese. Remove from heat.
6. Halve and toast buns. Divide buns between plates; fill with patties, caramelized onion and half the special sauce. Serve burgers with Old Bay fries and remaining sauce for dipping.
