Ingredients
Instructions
- Preheat oven to 425°F (220°C) with a rack in the top position. Wash and dry produce. Cut potatoes into 1/2-inch-thick wedges. Halve, peel and thinly slice the onion.
- Toss potato wedges on a baking sheet with a drizzle of oil and half the Old Bay seasoning. Season lightly with salt and pepper. Roast on the top rack until browned and crispy, 20-25 minutes.
- While potatoes roast, heat a large drizzle of oil in a medium nonstick pan over medium-high heat. Add sliced onion and cook, stirring occasionally, until browned and softened, 8-10 minutes. Add 1 teaspoon 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.
- In another small bowl, combine mayonnaise, ketchup, mustard and remaining Old Bay seasoning to taste. Set aside. Form ground beef into 2 equal balls (4 for 4 servings); season all over with salt and pepper.
- Heat a drizzle of oil in the same pan over medium-high heat. Once hot, add beef balls. Firmly flatten each with a spatula to create very thin patties. Cook until desired doneness, 3-4 minutes per side. In the last 1-2 minutes, top patties with shredded cheddar; cover pan to melt cheese. Remove from heat.
- While patties cook, halve and toast the potato buns. Divide buns between plates and fill with patties, caramelized onion and half the special sauce. Serve burgers with Old Bay fries on the side and remaining sauce for dipping.
Recipe Tips
For extra crispy fries, spread them in a single layer on the baking sheet and avoid overcrowding.
When smashing the beef patties, use a heavy spatula and press firmly to get thin, even patties with crispy edges.
If you prefer a spicier sauce, add a dash of hot sauce or extra Old Bay seasoning.
FAQ
Can I use a different type of cheese?
Yes, you can substitute white cheddar with provolone, mozzarella or your favorite melting cheese.
Can I make the fries in an air fryer?
Absolutely! Toss the potato wedges with oil and seasoning, then air fry at 400°F (200°C) for 15-20 minutes, shaking halfway through.
How do I prevent the patties from sticking to the pan?
Make sure the pan is hot before adding the beef and use enough oil. A nonstick pan also helps.
