Ingredients
Method
- Melt butter in a large oven-safe skillet over medium heat. Sauté onion, carrots, and celery with a pinch of salt until softened, about 6 minutes. Add garlic and cook 30 seconds.
- Sprinkle in flour and stir 1 minute. Gradually whisk in chicken broth and milk. Simmer until thick enough to coat a spoon, 3 to 4 minutes. Season with salt, pepper, and thyme.
- Remove from heat. Stir in chicken and peas until combined. If not using an oven-safe pan, transfer filling to a greased 9×13 baking dish.
- Preheat oven to 400°F. Cut each biscuit half crosswise into two thin rounds. Arrange in a single layer over the filling. Bake until biscuits are deep golden and the filling bubbles, 20 to 25 minutes.
- Let casserole rest 5 minutes, then spoon servings onto plates, making sure each gets biscuit and creamy filling.
Notes
If your filling looks a touch thick before baking, stir in a splash of warm broth. The biscuits will absorb some moisture as they bake, so a slightly looser base never hurts. For a cast iron skillet version, assemble and bake all in the same pan for fewer dishes.
