# How to make it:
01 - Set the oven to 400°F and prepare for baking.
02 - Melt butter and olive oil in a large ovenproof skillet over medium heat. Add diced onion, carrots, and celery; cook for 5 to 6 minutes until softened.
03 - Incorporate minced garlic, dried thyme, parsley, salt, and black pepper into the vegetables; cook for 1 minute until fragrant.
04 - Sprinkle flour over the mixture and cook while stirring continuously for 2 minutes to eliminate raw flour taste.
05 - Slowly add chicken broth and whole milk, stirring constantly to prevent lumps. Simmer and cook until sauce thickens slightly, approximately 4 to 5 minutes.
06 - Fold in shredded chicken and frozen peas, then remove skillet from heat.
07 - In a separate bowl, whisk together flour, baking powder, baking soda, salt, and black pepper.
08 - Use a pastry cutter or fingertips to incorporate cold cubed butter into dry ingredients until mixture resembles coarse crumbs.
09 - Stir grated cheddar cheese into the mixture, then gently mix in cold buttermilk until just combined, ensuring not to overmix.
10 - Drop heaping spoonfuls of biscuit dough evenly over the chicken filling in the skillet.
11 - Place skillet in oven and bake for 30 to 35 minutes until biscuits are golden brown, cooked through, and filling is bubbling.
12 - Allow the dish to rest for 5 minutes after removing from oven prior to serving.
