Preheat oven to 350 degrees.
Then, mix the bread and milk in a large bowl until it forms into a paste.
Add the ground chicken, ranch seasoning, eggs, and bread crumbs to the bread paste. Set aside.
In a small bowl, stir the hot sauce and blue cheese dressing—Reserve 1/4 cup of the hot sauce mixture for glazing the top of the meatloaf.
Pour the rest of the hot sauce mixture into the chicken mixture. Mix everything.
Place meat mixture onto a prepared baking sheet pan sprayed with cooking spray and form a loaf.
Brush the remaining hot sauce mixture over the top of the meatloaf.
Place the meatloaf into the oven and cook for 60 minutes or until the internal temperature reaches 165 degrees.
Let the meatloaf sit for 3-4 minutes, then slice and serve. Garnish with crumbled blue cheese and green onion.
