Ingredients
 

Main Ingredients

  • 1 tbsp olive oil
  • 3 tbsp unsalted butter
  • 1 cup diced yellow onion about 1 medium
  • 0.75 cup diced carrots
  • 0.75 cup diced celery
  • 2 tsp minced garlic
  • 0.33 cup all-purpose flour
  • 2.5 cup low-sodium chicken broth warm
  • 1 cup whole milk or half-and-half
  • 4 cup cooked shredded chicken rotisserie works great
  • 0.75 cup frozen peas no need to thaw
  • 1 tsp dried thyme
  • 2 tbsp chopped fresh parsley divided
  • 1.25 tsp kosher salt to taste
  • 1 tsp black pepper
  • 16 oz refrigerated biscuit dough split large biscuits in half if needed
  • 0.5 cup shredded cheddar cheese optional

Instructions

Preparation Steps

  • Heat oven to 400°F. Grease a 9x13-inch baking dish.
  • Warm olive oil and 1 tbsp butter in a large skillet over medium heat.
  • Sauté onion, carrots, and celery until slightly tender, 5–6 minutes. Stir in garlic for 30 seconds.
  • Melt remaining butter in the pan. Sprinkle in flour and cook, stirring, 1–2 minutes to form a roux.
  • Slowly whisk in warm broth, then milk. Simmer, stirring, until thick and silky, 3–5 minutes.
  • Fold in chicken, peas, thyme, salt, pepper, and half the parsley. Taste and adjust seasoning.
  • Spread the filling in the dish. Sprinkle cheddar over the top if using.
  • Arrange biscuits evenly over the filling. Split large biscuits in half for more coverage.
  • Bake until biscuits are deep golden and the filling bubbles, 22–28 minutes. Rest 10 minutes.
  • Finish with remaining parsley and serve warm.

Notes

Variation: Swap peas for a mixed vegetable blend or add a pinch of smoked paprika to the gravy. For a cheesy crust, brush biscuit tops with a little milk and sprinkle with Parmesan before baking. Storage: Cover leftovers and refrigerate up to 3 days; reheat at 350°F until hot.
