Instructions

  1. Adjust oven racks to top and middle positions. Preheat oven to 425°F. Wash and dry produce. Cut potatoes into ½-inch-thick wedges. Halve, peel and thinly slice onion. Cut each cheddar slice into 6 small squares (12 total). Trim and discard root end from lettuce; dry leaves thoroughly, then chop into bite-size pieces.
  2. Toss potatoes on a baking sheet with a drizzle of oil, fry seasoning, salt and pepper. Roast on top rack, tossing halfway through, until crisp and tender, 20-25 minutes.
  3. Heat a large drizzle of oil in a large nonstick pan over medium-high heat. Add onion; cook, stirring occasionally, until browned and softened, 8-10 minutes. Lower heat and add a splash of water if onion browns too quickly.
  4. Add 2 tablespoons water, 1 teaspoon Worcestershire sauce and 1 teaspoon sugar to pan with onion; cook, stirring, until caramelized, 2-3 minutes. Season with salt and pepper. Transfer to a small bowl. Wipe out pan.
  5. In a large bowl, combine beef, 1 teaspoon Worcestershire sauce, salt and pepper. Form mixture into six ½-inch-thick patties.
  6. Heat a drizzle of oil in the same pan over medium-high heat. Add patties; cook to desired doneness, 2-3 minutes per side. Drain excess grease if needed. Turn off heat; top each patty with two squares of cheddar. Cover pan until cheese melts, 1-2 minutes. While cheese melts, place buns directly on middle oven rack; toast until warmed through, 2-3 minutes.
  7. In a medium bowl, toss together lettuce, dressing and Parmesan. Season with salt and pepper. Once buns are toasted, gently separate tops from bottoms. Fill buns with caramelized onion and patties. Divide sliders, salad and oven fries between plates. Serve with ketchup and smoky mustard on the side.

Recipe Tips

For extra crispy fries, soak potato wedges in cold water for 30 minutes before roasting.

If you don’t have fry seasoning, substitute with a mix of paprika, garlic powder and onion powder.

Use a cast-iron skillet for the best sear on the patties.
