Instructions

  1. Step 1: Combine 1 lb ground chicken with 1 tsp salt, 1/2 tsp black pepper, and 1/2 tsp garlic powder in a bowl. Mix gently and form into eight 2-inch diameter, 1/2-inch thick patties.
  2. Step 2: In a small bowl, mix 1/2 cup white vinegar and 1 tbsp granulated sugar until sugar dissolves. Add the thinly sliced 1 medium red onion and let them soak for at least 15 minutes to pickle.
  3. Step 3: Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add the chicken patties and cook for 4 minutes on each side until golden brown and cooked through (internal temperature 165°F).
  4. Step 4: While chicken cooks, mix 1/4 cup mayonnaise with 2 tbsp Dijon mustard in a small bowl to make the tangy sauce.
  5. Step 5: Toast 8 small slider buns lightly in a separate pan or toaster.
  6. Step 6: Assemble sliders by spreading about 1 tbsp of the tangy sauce on the bottom bun, topping with a chicken patty, then 1-2 tbsp of the pickled onions, and finally the top bun. Serve warm.

How do I scale Pan-Seared Chicken Sliders with Pickled Onions and Tangy Sauce for a different number of people?

The recipe is written for 8 servings. Multiply each ingredient by (your serving target / 8). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
