Ingredients
 

Main Ingredients

  • 1 tbsp olive oil
  • 4 tbsp unsalted butter
  • 1 cup diced yellow onion
  • 0.75 cup diced carrots
  • 0.5 cup diced celery
  • 1.5 tsp minced garlic
  • 0.33 cup all-purpose flour
  • 2 cup low-sodium chicken broth
  • 1 cup whole milk
  • 0.5 cup sour cream for extra creaminess
  • 1 tsp chopped fresh thyme
  • 1 tsp dried parsley
  • 1.25 tsp kosher salt adjust to taste
  • 0.75 tsp black pepper
  • 0.5 tsp paprika optional, for color
  • 3 cup cooked shredded chicken rotisserie works great
  • 0.75 cup frozen peas no need to thaw
  • 1 cup shredded sharp cheddar cheese divided
  • 16 oz refrigerated biscuit dough cut into quarters

Instructions

Preparation Steps

  • Heat oven to 400°F. Lightly grease a 9x13-inch baking dish.
  • Warm olive oil and 2 tbsp butter in a large skillet over medium heat.
  • Soften onion, carrots, and celery in the skillet, stirring occasionally, 5–6 minutes.
  • Stir in garlic and cook until fragrant, about 30 seconds.
  • Melt remaining 2 tbsp butter. Sprinkle in flour and cook, stirring, 1 minute.
  • Whisk in broth, then milk, a little at a time. Simmer until thick and silky, 3–5 minutes.
  • Off heat, stir in sour cream, thyme, parsley, salt, pepper, paprika, and half the cheese.
  • Fold in chicken and peas until evenly distributed.
  • Spread the creamy filling in the prepared baking dish.
  • Arrange biscuit quarters over the top and sprinkle with remaining cheese.
  • Bake 18–22 minutes, until biscuits are deep golden and the filling bubbles at the edges.
  • Let the casserole rest 10 minutes before serving so the sauce sets.

Notes

Variation: Swap peas for chopped steamed broccoli, or add a pinch of cayenne for gentle heat. To store, refrigerate leftovers in an airtight container for up to 3 days; reheat covered at 350°F until warmed through.
