Instructions

Instructions

  • Prepare your grill for high direct heat and clean the grates; oil the grates lightly if desired.
  • In a large skillet, melt 2 tablespoons butter over medium-high heat. Add the sliced onions and sprinkle with 1/2 teaspoon salt and 1/2 teaspoon pepper. Cook, stirring occasionally, until the onions are deeply browned and crispy (about 12–15 minutes); reduce heat if they are browning too quickly. Transfer the crispy onions to a plate to drain.
  • Season the 4 burger patties on both sides with the remaining 1/2 teaspoon salt and 1/2 teaspoon pepper.
  • Place the patties on the hot grill and cook about 5 minutes per side for medium (adjust time for desired doneness). Do not press down on the patties while cooking.
  • With about 2 minutes remaining, place a blue cheese slice on each patty and close the grill (or cover) so the cheese can melt.
  • During those last 2 minutes, place the 4 burger buns cut-side down on the grill and toast up to 30 seconds until lightly browned.
  • Remove the patties and buns from the grill.
  • Assemble each burger: spread 1 tablespoon sweet and spicy mustard on the bottom bun, add some baby arugula or baby kale, place the burger with melted blue cheese, add tomato slices, top with the crispy fried onions, and finish with the top bun.
  • Serve the burgers immediately.

Notes

Leftovers are best stored separate. Leave assembly for when you’re ready to enjoy your burgers! The arugula, tomatoes, arugula, and buns are best fresh. The patties will be good for 3-4 days in an airtight container in the fridge.
To reheat, you can pop the patties in the microwave at 30 second intervals until they’re heated through. You can also place them in a skillet, covered, over medium heat until they’re warm.
For the onions, you can honestly enjoy these on your burger cold! If you prefer them hot, you can definitely reheat them in the microwave or in a skillet. I would suggest lining your plate with paper towel to microwave them. This will keep them as crisp as possible.
