Start by heating a large skillet over medium-high heat. Cook the bacon pieces until crispy and golden, then remove them to a plate lined with paper towels. Drain excess fat, leaving about two tablespoons in the skillet for added flavor.
Using the same skillet, add your ground chicken and chopped onion. Cook for 5-7 minutes, stirring occasionally. You want the chicken fully cooked and the onions soft and translucent.
In a mixing bowl, whisk together the ranch seasoning packet, milk, and cornstarch. Pour this mixture into the skillet with the chicken and onions. Stir well and cook for 3-4 minutes. The sauce will thicken slightly and coat everything beautifully.
Reduce the heat to low and stir in the shredded mozzarella. Once it’s melted and mixed in, sprinkle the chopped cheddar cheese and crispy bacon pieces on top. Gently fold them into the sauce, but don’t overmix – those cheesy bursts are part of the magic.
Toast your favorite buns, scoop the chicken mixture on top, and serve immediately. Enjoy the rich flavors and creamy texture packed into every bite!
