Ingredients

Instructions

  1. Step 1: In a small bowl, combine 1/4 cup white vinegar and 1 tbsp sugar. Add 1 small thinly sliced red onion and let sit at room temperature for at least 15 minutes to quick-pickle.
  2. Step 2: Meanwhile, preheat a skillet over medium-high heat. In a bowl, mix 1 lb ground beef with 1 tsp salt and 1/2 tsp black pepper. Form into eight 2-inch diameter patties.
  3. Step 3: Add 1 tbsp olive oil to the hot skillet and cook the patties for 3-4 minutes per side until browned and cooked through.
  4. Step 4: In a small bowl, mix 1/3 cup mayonnaise with 1 minced garlic clove to make garlic aioli.
  5. Step 5: Assemble sliders by spreading aioli on the bottom half of each of the 8 slider buns, topping with a beef patty, and finishing with a few pickled red onion slices. Cover with the bun tops and serve immediately.

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.
