One-Skillet Chicken Pot Pie Casserole

by

Introduction

Few dishes say “comfort food” quite like a classic chicken pot pie, but a traditional crust from scratch can be a labor-of-love project for a busy weeknight. This Skillet Chicken Pot Pie Casserole strips away the fuss without losing an ounce of the flavor.

By cooking the rich, creamy chicken and vegetable filling directly in a cast-iron skillet and topping it with a quick, buttery biscuit layer, you get a beautiful “all-in-one” casserole. It cuts down on the dishes, maximizes efficiency, and delivers that signature velvety gravy and golden, flaky top in under 45 minutes.

Ingredients

  • The Meaty Filling:
    • 2 tablespoons Unsalted Butter
    • 1 tablespoon Olive Oil
    • 1 small Yellow Onion, diced
    • 2 cloves Garlic, minced
    • 1 ½ cups Mixed Vegetables (carrots, peas, corn, and celery—frozen works perfectly)
    • 3 cups Cooked Chicken, shredded or cubed (Rotisserie chicken is a great shortcut)
  • The Velvety Gravy:
    • ⅓ cup All-Purpose Flour
    • 2 cups Low-Sodium Chicken Broth
    • ½ cup Heavy Cream or Whole Milk
    • 1 teaspoon Poultry Seasoning (or dried thyme and rosemary)
    • Salt and Black Pepper to taste
  • The Flaky Topping:
    • 1 can (16.3 oz) Refrigerated Grand Biscuits (or a batch of your own quick drop biscuit dough)
    • 2 tablespoons Butter, melted (for brushing)
    • ¼ teaspoon Garlic Powder or Dried Parsley

Equipment Needed

  • 10 or 12-inch Oven-Safe Skillet: A well-seasoned cast-iron skillet is ideal.
  • Wooden Spoon or Whisk: For building the gravy.

Time & Servings

  • Prep Time: 15 minutes
  • Bake Time: 20–25 minutes
  • Total Time: ~40 minutes
  • Servings: 6 people

Step-by-Step Instructions

1. Preheat and Sauté

Preheat your oven to 375°F (190°C). Melt the butter and olive oil in your oven-safe skillet over medium heat. Add the diced onion and minced garlic, sautéing for 3–4 minutes until they are soft and fragrant.

2. Add the Veggies

Stir in your mixed vegetables and cook for an additional 2–3 minutes just to heat them through and release any excess moisture.

3. Build the Roux

Sprinkle the flour evenly over the vegetables. Stir constantly for 1–2 minutes to coat the veggies. This cooks out the raw flour taste and creates the thickening base for your pot pie gravy.

4. Simmer the Gravy

Slowly pour in the chicken broth and heavy cream, whisking continuously to prevent lumps from forming. Bring the liquid to a gentle simmer. Add the poultry seasoning, salt, and pepper. Let it simmer for 3–5 minutes until the sauce bubbles and thickens into a rich gravy.

5. Fold in the Chicken

Stir the shredded cooked chicken into the thickened gravy until everything is completely combined and piping hot. Turn off the stovetop heat.

6. Top and Bake

Open your can of biscuits. Cut each raw biscuit into quarters (or halves if you prefer larger biscuits) and arrange them in a single layer completely covering the top of the chicken filling. Brush the tops of the dough with melted butter mixed with a pinch of garlic powder or parsley.

7. Bake to a Golden Puff

Transfer the entire skillet directly into the preheated oven. Bake for 20–25 minutes. The casserole is done when the biscuit topping is puffed, deep golden brown, and the creamy chicken filling is bubbling up around the edges.

Tips and Tricks

  • The Biscuits Must Be Cooked Through: Because the biscuits are sitting on top of a wet filling, the bottoms can sometimes stay doughy if the oven isn’t hot enough. Cutting the biscuits into smaller quarters ensures they bake all the way through quickly.
  • Keep an Eye on the Pan: If your cast-iron skillet is deep, the filling might bubble over slightly. Place a baking sheet on the rack beneath the skillet just in case there are any drips.
  • Vegetable Secret: If using frozen veggies, don’t worry about thawing them beforehand. Throwing them in frozen helps them keep their structural integrity so they don’t turn to mush during the bake.

Variations

  • Crescent Topping: If you prefer a smoother, lighter top similar to a Creamy Broccoli Chicken Crescent Bake, you can unroll a sheet of crescent dough over the skillet instead of using biscuits.
  • Turkey Leftover Option: This is an incredible post-holiday recipe. Swap the chicken for leftover holiday turkey and add a spoonful of cranberry sauce on the side.
  • Cheesy Biscuit Top: Sprinkle ½ cup of shredded cheddar cheese over the biscuits during the last 5 minutes of baking for a savory cheddar-bay twist.

Serving Suggestions

  • The Complete Meal: Since this dish has your protein, starches, and vegetables all built into one skillet, it doesn’t require heavy sides. Pair it with a simple, crisp green salad tossed in a light vinaigrette to cut through the richness of the cream gravy.

Storage Instructions

  • Refrigeration: Store leftovers in an airtight container for up to 3 days.
  • Reheating: To keep the biscuit topping from getting soggy, reheat portions in the oven or air fryer at 350°F for 5–8 minutes until the filling is hot.

Conclusion

This Skillet Chicken Pot Pie Casserole delivers all the nostalgic, heartwarming goodness of a traditional pie with a fraction of the effort. It is bubbly, buttery, and guaranteed to become a regular in your weeknight dinner rotation.
