Preheat griddle (or large cast iron) to medium heat. Cook bacon until crispy and move to a plate.
Sautee the onions in the bacon grease until soft and translucent. Remove and move to the side.
Roll beef into eight 3-ounce balls
Clean griddle top or cast iron and coat with canola oil, bring to medium/high heat.
Smash burger balls with back of a spatula and use parchment paper to reduce sticking. Season with salt and pepper to taste. Keep a close eye on these because they can overcook quickly.
Flip once crust has formed (1-1/2 minutes), mop with Lil Bubbies BBQ sauce, add onions, top with cheese. Remove once crust on the bottom has formed (should be done once you’ve topped all the burgers – remember to move fast!)
Remove from griddle. Toast burger buns and build burgers with the bacon slices, pickles, and abundant Lil bubbies BBQ sauce.
