Ingredients:
- 2 Tbsp Unsalted Butter
- 1 medium Yellow Onion, diced finely
- 2 stalks Celery, diced
- 1/4 cup All-Purpose Flour
- 1 cup Low Sodium Chicken Broth
- 1/2 cup Whole or 2% Milk (for filling)
- 1 (10.5 oz) can Cream of Chicken Soup
- 3 cups Cooked Chicken, shredded or cubed
- 1 bag (10 oz) Frozen Mixed Vegetables (Peas, carrots, corn, green beans)
- 1/2 tsp Dried Thyme
- Salt and Black Pepper, to taste
- 2 cups Bisquick Baking Mix
- 1 cup Whole or 2% Milk (for topping)
- 1 large Egg
Instructions:
- Preheat oven to 400°F (200°C). Lightly grease a 9x13-inch (3-quart) casserole dish.
- Melt the butter in a large skillet over medium heat. Add the diced onion and celery and cook until softened, about 5–7 minutes.
- Sprinkle the flour over the softened vegetables. Cook, stirring constantly, for 1 minute to build the roux and remove the raw flour taste.
- Gradually whisk in the chicken broth and 1/2 cup milk until smooth. Bring the mixture to a gentle simmer, stirring constantly until it thickens slightly (about 3 minutes).
- Reduce heat to low. Stir in the canned cream of chicken soup, shredded cooked chicken, frozen mixed vegetables, thyme, salt, and pepper.
- Cook until the mixture is hot and bubbly throughout. Pour the entire hot filling into the prepared casserole dish.
- In a medium bowl, whisk together the Bisquick baking mix, the remaining 1 cup milk, and the large egg until just combined. Do not overmix.
- Immediately and evenly pour the Bisquick batter over the hot filling in the casserole dish.
- Bake for 30–35 minutes, or until the topping is golden brown, puffed up, and firm to the touch in the center.
- Remove from the oven and let the pot pie rest for 5–10 minutes before serving. This allows the filling to settle and the sauce to thicken slightly.
