1. Start by patting the chicken breasts dry and slightly flattening them if needed. Rub the chicken with olive oil and ranch seasoning on both sides, ensuring an even coating for maximum flavor.

2. In a skillet over medium heat, cook the bacon until crispy. Transfer the cooked bacon to paper towels to drain and remove any excess grease.

3. In the same skillet (or a clean one), cook the seasoned chicken over medium heat for about 6–7 minutes per side, or until the internal temperature reaches 165°F. Allow the chicken to rest briefly, then slice it.

4. Lightly toast the sandwich buns in the skillet or a toaster to give them a delightful crunch.

5. Spread the ranch dressing on the bottom half of each bun, then layer with shredded lettuce and tomato slices (if using). Add the sliced chicken, a slice of cheddar cheese, and two slices of bacon. Top with the other half of the bun.

6. Serve the Cheesy Chicken Bacon Ranch Sandwich immediately, while the cheese is melty and the flavors are at their peak.
