Air Fryer Hamburgers

• •
  1 lbs 90/10 Ground Beef
• •
  1 tbsp Olive oil

  Regular (not extra-virgin) olive oil for high-heat cooking. EVOO for dressings.

• •
  2 tsp Mustard, Dijon

  Dijon mustard — Grey Poupon or store brand. Spicier than yellow mustard.

• •
  0.5 tsp Garlic powder
• •
  0.5 tsp ½ teaspoon kosher salt
• •
  0.5 tsp ½ teaspoon ground black pepper
• •
  4 Bread, Brioche Bun(340g)

Instructions

1. 1Place the ground beef in a large mixing bowl and add a drizzle of olive oil, Dijon mustard, garlic powder, salt, and pepper. Gently stir with a fork to combine, handling the meat as little as possible to keep the burgers tender.
2. 2Gently shape the beef into 4 equal patties approximately ½-inch thick. Using your thumb, press a shallow indentation in the center of each patty to prevent them from puffing up during cooking.
3. 3Heat a large skillet over medium-high heat and lightly coat the bottom with olive oil. Once the oil shimmers, carefully place the patties in the skillet, leaving space between each one.
4. 4Cook the patties for 3–4 minutes without moving them over medium-high heat, until the bottom is golden brown and develops a crust. Flip each patty and cook for an additional 2–3 minutes, until the internal temperature reaches 155°F when measured with a meat thermometer.
5. 5Transfer the cooked burgers to a clean plate and let them rest for 1–2 minutes while you lightly toast the brioche buns cut-side down in the same skillet over medium heat for 1–2 minutes, until lightly golden.
6. 6Assemble one burger by placing a patty on a toasted bun with your choice of toppings.
7. 7Place the remaining 3 cooked patties (without buns) into an airtight container while still warm. Store in the refrigerator for up to 4 days. Reheat gently in a skillet over medium heat for 2–3 minutes until warmed through, then assemble with fresh toasted buns before serving.
