In a large bowl, combine ground chicken, egg, bread crumbs, ranch seasoning, minced garlic, diced onion, and shredded cheddar cheese; stir gently until just combined.
Line a baking sheet or cutting board with parchment and press the mixture into evenly sized burger patties, shaping all before cooking.
Heat a large skillet over medium heat and add a small amount of oil.
Cook the patties for about 6-8 minutes per side, adjusting for thickness, until they’re thoroughly cooked through.
To build the burgers, set the cooked patties on buns and layer with crispy bacon, fresh lettuce, sliced tomatoes, and a drizzle of ranch dressing; add any other veggies you prefer.
Serve immediately for best taste and enjoy your delicious Cheddar Ranch Chicken Burgers!
