# Method:
01 - Set the oven to 400°F and allow it to fully preheat.
02 - In a large ovenproof skillet or baking dish, melt butter and olive oil over medium heat. Add diced onion, carrots, and celery; sauté for 5 to 6 minutes until softened.
03 - Stir in minced garlic, dried thyme, dried parsley, salt, and black pepper. Cook for 1 minute until the mixture is fragrant.
04 - Sprinkle in all-purpose flour and cook for 2 minutes, stirring constantly to form a roux.
05 - Gradually pour in chicken broth and whole milk while stirring to prevent lumps. Bring to a simmer and cook for 4 to 5 minutes until the sauce slightly thickens.
06 - Stir shredded chicken and frozen peas into the sauce. Remove skillet from heat.
07 - In a mixing bowl, whisk together flour, baking powder, baking soda, salt, and black pepper.
08 - Incorporate cold cubed butter using a pastry cutter or fingertips until the mixture resembles coarse crumbs.
09 - Fold in grated cheddar cheese, then add cold buttermilk. Stir gently just until combined; avoid overmixing.
10 - Drop heaping spoonfuls of biscuit dough evenly over the chicken filling in the skillet.
11 - Place in the oven and bake for 30 to 35 minutes until biscuits are golden brown and cooked through and filling is bubbling.
12 - Allow the dish to rest for 5 minutes prior to serving.
