  • 4 cups chicken broth (US: 946ml, Metric: 950ml)
  • 1 cup heavy cream (US: 237ml, Metric: 240ml)
  • 1 teaspoon dried thyme
  • 1/2 teaspoon dried rosemary
  • 1/4 teaspoon ground black pepper
  • 1/2 teaspoon salt (or to taste)
  • 3 cups cooked chicken, shredded or diced (US: about 450g, Metric: about 450g)
  • 1 cup frozen peas
  • 1 cup frozen corn
  • 2 cups all-purpose flour (US: 240g, Metric: 300ml)
  • 1 tablespoon baking powder
  • 1 teaspoon salt
  • 1/2 cup (1 stick) cold unsalted butter, cut into cubes (US: 113g, Metric: 115g)
  • 3/4 cup shredded cheddar cheese (US: about 75g, Metric: about 75g)
  • 3/4 cup milk (US: 177ml, Metric: 180ml)

Instructions:

  1. Preheat oven to 400°F (200°C). Grease a 9x13 inch baking dish.
  2. Melt butter in a large Dutch oven or oven-safe skillet over medium heat. Add onion, carrots, and celery and sauté until softened.
  3. Whisk in flour and cook for 1 minute. Gradually whisk in chicken broth until smooth. Stir in heavy cream, thyme, rosemary, salt, and pepper. Bring to a simmer and cook until thickened.
  4. Stir in cooked chicken, peas, and corn. Simmer for 5 minutes.
  5. In a large mixing bowl, whisk together flour, baking powder, and salt. Cut in cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. Stir in cheddar cheese.
  6. Gradually add milk, stirring until just combined. Do not overmix.
  7. Pour chicken mixture into the prepared baking dish. Drop spoonfuls of biscuit dough evenly over the chicken mixture.
  8. Bake for 25-30 minutes, or until biscuits are golden brown and cooked through. This is one of the best chicken casserole recipes.
  9. Let cool for a few minutes before serving.
