Preheat oven to 400 degrees F.
Lay out bacon strips on rimmed baking sheet pan, lined with parchment paper or foil. Bake until brown and crisp, about 10 to 12 minutes, depending on thickness. Remove, drain on paper towels, and set aside. Alternately, bacon can also be cooked in the microwave or on the stovetop.
Preheat a gas grill, charcoal grill, or indoor grill to medium-high heat.
In a large skillet over medium-high heat, melt 1 tablespoon butter and 1 tablespoon olive oil. Set aside remaining butter for bread. Saute onions and both peppers until soft and caramelized.
Meanwhile, combine ketchup, barbecue sauce, bourbon, mustard, and sugar in a small saucepan. Bring to a light simmer and continue to cook until sugar is dissolved and sauce is thick, about 3 to 4 minutes.
For Beercheese, combine first 5 ingredients in food processor, and with machine running, drizzle in beer until mixture is smooth and well combined.
Divide ground chuck into 6 square-shaped patties, approximately the size of Texas toast. Season with salt and pepper. Brush grill with vegetable oil. Place patties on grill and cook, turning once until done, approximately 5 to 7 minutes until desired doneness. Once flipped, brush tops of patties with BBQ glaze.
Meanwhile, lightly butter both sides of each slice of Texas toast and grill on either side for 1 to 2 minutes along outer edges of grill, until lightly browned and toasted.
To assemble, spread 6 slices of Texas toast liberally with beercheese, approximately 2 tablespoons per slice. Top with bacon strips and burger patties. Top burgers with caramelized onion and pepper mixture. Spread the remaining slices of toast with additional BBQ glaze, about 1 tablespoon per slice, and invert onto burger patties. Enjoy!
Cook's Note: The beercheese spread is incredibly easy to make and stores well in the refrigerator. Double or even triple the recipe and use the leftovers for a dip; serve with crackers and vegetables, such as celery, carrots, cucumbers, and radishes.
