• Preheat the grill to medium-high, about 400° F.

Cook the bacon

• Place a heat-safe cast-iron skillet directly on the grill grates. Add the bacon to the skillet. Cook 4-5 minutes per side until the bacon is rendered and as crisp as you'd like. Carefully transfer to a paper towel-lined plate to drain any excess oil. Set aside.
• Bake at 375° F for 10-12 minutes, until rendered and as crisp as you'd like. Remove from the oven and transfer to a paper towel-lined plate to drain any excess oil. Once cool enough to handle, transfer to an airtight container and store in the refrigerator for up to 3 days.

Grill the burgers

• Once the bacon is about halfway cooked, begin grilling the burgers. Just before placing the patties on the grill, generously spray a wad of paper towels with nonstick cooking spray.
• Use grilling tongs to run the paper towel over the grill grates, generously oiling the grill grates. Place the burgers on the grill. Close the lid and grill for 3 minutes per side for medium doneness. If you'd like to add cheese to your burgers, do so when there are 2 minutes left of grilling time.

Toast the brioche buns

• Halve the burger buns. Lightly spritz the cut side with nonstick cooking spray. Place the buns directly on the grill grates, grilling for 90 seconds to 2 minutes, just until toasty. Keep a close eye on them to prevent burning – they toast very quickly!

Serve

• Place the grilled burgers, cooked bacon, and toasted buns on individual platters. Set up your burger bar by placing the platters on a table or serving station, along with your toppings and condiments of choice.
