Ingredients
  

  • ½ cup chopped onion
  • ¼ cup butter
  • 4 cups diced, cooked chicken meat
  • 4 cups chicken broth
  • 2 tsp white sugar
  • ½ cup chopped celery
  • 2 cloves garlic, minced
  • ½ cup chopped baby carrots
  • 1 tsp dried basil
  • ½ cup all-purpose flour
  • 1 can of peas, drained
  • ½ tsp ground black pepper

Biscuit

  • 2 tsp dried basil
  • 2 cups buttermilk baking mix
  • cups milk

Instructions
 

  • Preheat the oven to 350°F (175°C) and lightly grease a 9x13-inch baking dish.
  • In a large skillet over medium-high heat, melt the butter, then cook and stir the onion, celery, carrots, and garlic until tender.
  • Stir in flour, sugar, salt, basil, and pepper.
  • Let it boil for 1 minute, then reduce the heat and stir in the peas.
  • Simmer for 5 minutes before adding the cooked chicken and stirring to combine.
  • Pour the chicken mixture into the prepared baking dish.
  • For the biscuits, mix baking mix and basil in a large bowl, then stir in milk to form a dough.
  • Divide the dough into 6 to 8 balls and flatten each one using your palm on floured wax paper to create rounds.
  • Arrange the biscuit rounds on top of the chicken mixture.
  • Bake for 30 minutes, then cover with foil and bake for an additional 10 minutes.
  • Serve by spooning the chicken mixture over the biscuits.

Notes

  • Rotisserie chicken works great here—it's flavorful and a time-saver.
  • Add a pinch of cayenne for subtle heat and depth.
  • Use frozen mixed veggies as a shortcut instead of chopping fresh.
  • Flatten biscuits slightly thinner for extra golden, crisp edges.
