how to make Chicken Pot Pie Casserole

First, gather your tools and preheat the oven so everything moves smoothly. You’ll build a creamy, herb-scented filling on the stove, fold in tender chicken, and then give it a biscuit blanket that bakes to golden perfection. Next, keep an eye on the texture as it thickens — you want a gravy-like consistency that will bubble under the biscuits without turning gluey. Once the topping is done and the filling is bubbling at the edges, let the Chicken Pot Pie Casserole rest for a few minutes so the filling settles; this makes it easier to serve and keeps the biscuits from breaking apart.

When you serve, slice a generous square, making sure each portion has a bit of browned biscuit and a spoonful of the creamy vegetables and chicken. Finally, sprinkle fresh parsley if you like a bright finish — it adds a lovely color contrast and a hint of freshness to each warm, comforting bite.

ingredients

• 2 cups cooked chicken, cubed (rotisserie chicken works great for this),
• 1 cup frozen peas,
• 1 cup diced carrots,
• 1/2 cup diced onion,
• 1/4 cup unsalted butter,
• 1/4 cup all-purpose flour,
• 2 cups chicken broth,
• 1/2 cup whole milk (or half-and-half for a creamier filling),
• 1 teaspoon garlic powder,
• 1 teaspoon thyme (fresh or dried),
• 1/2 teaspoon black pepper,
• 1 can (16 oz) refrigerated biscuit dough (or homemade biscuit dough if preferred),
• Salt to taste,
• Fresh parsley (optional, for garnish)

Butter is the backbone of the filling here — it sautés the onions and carrots, and when combined with flour it creates a roux that thickens the sauce and gives the casserole a silky mouthfeel. Chicken broth, rather than water, deepens the savory note; if you use low-sodium broth, you control the salt more easily. Whole milk or half-and-half adds richness; swap in a plant-based milk and a splash of non-dairy creamer for a dairy-free option, although the texture will be slightly lighter.

Frozen peas and diced carrots keep the casserole colorful and offer different textures: sweet, tender peas and slightly firm carrots. Rotisserie chicken is a perfect shortcut because it’s already flavorful and moist, but leftover roast or poached chicken work just as well. If you’d like to make this vegetarian, substitute the chicken with sautéed mushrooms and extra white beans for protein, and use vegetable broth instead.

directions

Preheat the oven to 375°F (190°C) and grease a 9×13-inch baking dish with cooking spray or butter so the casserole won’t stick. In a large skillet over medium heat, melt the butter and add the diced onions and carrots, sautéing for about 3–4 minutes until the onions become soft and translucent — this is when it starts to smell amazing. Stir in the frozen peas and cook for another two minutes; the peas will thaw quickly and brighten the pan.

Sprinkle the flour over the vegetables and stir to combine, cooking for another minute to form a light roux. Slowly pour in the chicken broth while stirring constantly to prevent lumps, then add the milk, garlic powder, thyme, and black pepper. Bring the mixture to a gentle simmer and cook until it thickens, about five minutes; don’t worry if it looks a little thick at first — it will loosen slightly when you add the chicken.

Stir in the cubed cooked chicken and let everything warm through for two to three minutes so the flavors marry. Give the filling a quick taste and adjust seasoning with salt as needed — a final check here will make sure the Chicken Pot Pie Casserole is perfectly seasoned. Pour the filling into the prepared baking dish and spread it evenly.

Open the can of refrigerated biscuit dough and tear each biscuit into quarters, arranging the pieces evenly over the top of the filling so you get biscuits across the whole surface. You’ll notice the edges turn golden in the oven and the center biscuits puff up beautifully. Bake for 25–30 minutes, or until the biscuit topping is golden brown and the filling bubbles around the sides. Let the casserole rest for 5–10 minutes before serving so the filling firms up and the squares come out cleanly.

how to serve Chicken Pot Pie Casserole

Serve this Chicken Pot Pie Casserole straight from the baking dish for a family-style dinner, or plate individual portions with a spoonful of parsley on top for a fresh finish. It pairs beautifully with a crisp green salad or roasted root vegetables to add a contrasting texture. For a cozy weeknight, a simple side of steamed broccoli or buttery green beans keeps things balanced and colorful on the plate.

This casserole is great for holiday leftovers, potlucks, or a comforting Sunday supper. The biscuit top offers a golden, slightly flaky texture while the filling stays creamy and herby, so each serving looks inviting and tastes like a warm, familiar meal.

how to store Chicken Pot Pie Casserole

Cool leftover Chicken Pot Pie Casserole to room temperature before storing. In the refrigerator, keep it tightly covered for up to 3–4 days in an airtight container or covered baking dish. For longer storage, freeze portions in freezer-safe containers for up to 2–3 months; thaw overnight in the refrigerator before reheating.

To reheat, warm individual portions in the microwave for a quick meal, or reheat the whole casserole in a 350°F oven for about 20–25 minutes to revive the biscuit’s crisp edge. If you want a super-crisp topping, remove any plastic wrap, place the dish in the oven uncovered, and broil for a minute or two at the end — watch closely so it doesn’t burn.

tips for perfect Chicken Pot Pie Casserole

• Use warm (not cold) milk when adding to the roux to prevent the sauce from seizing or forming lumps.
• If your filling looks too thin before baking, simmer a little longer; if it’s too thick, stir in a splash of broth or milk.
• For evenly browned biscuits, rotate the dish halfway through baking and check the edges — they often brown first.
• Taste before you bake and adjust salt and pepper; a little extra seasoning makes a big difference in a creamy dish.
• If you want a more herb-forward casserole, add a tablespoon of chopped fresh thyme or a teaspoon of rosemary to the filling.

If you like experimenting with casseroles, this variation technique works well when I borrow ideas from other comfort dishes, like the savory layers in a French onion-style chicken casserole. It’s a great way to adapt flavors and keep the Chicken Pot Pie Casserole feeling new.

variations

Chicken Pot Pie Casserole is very forgiving, so feel free to switch ingredients to suit your tastes. For a gluten-free version, use a gluten-free flour blend for the roux and top with gluten-free biscuit dough; the texture will be slightly different but still delicious. Make it dairy-free by swapping the butter for olive oil or dairy-free spread and using unsweetened almond milk plus a touch of non-dairy creamer for richness.

Turn it into a southwestern Chicken Pot Pie Casserole by adding diced green chiles, a teaspoon of cumin, and swapping peas for black beans and corn; serve with a dollop of sour cream and chopped cilantro. For a lighter version, use breast meat, low-fat milk, and whole-wheat biscuit dough, and load up on extra vegetables like celery and mushrooms.

FAQs

Q: Can I make Chicken Pot Pie Casserole ahead of time?
A: Yes — assemble the casserole without baking and cover it tightly in the refrigerator for up to 24 hours. When you’re ready, remove it from the fridge and bake as directed; you may need an extra five to ten minutes if the filling is cold. This is a great strategy for busy weeknights or entertaining.

Q: Can I use raw chicken instead of cooked chicken?
A: If you use raw chicken, dice it small and cook it thoroughly before adding it to the sauce, or poach the chicken in the broth first so it stays moist. Using pre-cooked chicken keeps the timing simple and ensures the pieces stay tender in the filling. Rotisserie chicken is a favorite shortcut because it adds flavor without extra work.

Q: My filling is lumpy after I add the milk — what went wrong?
A: Lumps usually happen when cold milk hits a hot roux or if you add the milk too quickly. To prevent this, whisk constantly while adding liquid and use warm milk if possible. If lumps form, a quick whisk over low heat or a short pass with an immersion blender will smooth the sauce.

Q: Can I make mini Chicken Pot Pie Casseroles in ramekins?
A: Absolutely — divide the filling into individual ramekins and top each with a biscuit piece or pastry. Bake until the tops are golden and the centers bubble; smaller dishes may bake a bit faster, so start checking around 18–20 minutes. Individual portions are lovely for dinner parties or when you want a special presentation.
