Ingredients You’ll Need

• 2 cups cooked chicken, shredded or diced (a great use for rotisserie chicken!)
• 1 tablespoon olive oil (for sautéing the veggies)
• 1 medium yellow onion, diced (for a sweet, savory base)
• 3 cloves garlic, minced (because everything’s better with garlic)
• 2 cups mixed vegetables, frozen or fresh (like peas, carrots, and green beans)
• 1/3 cup all-purpose flour (to thicken our creamy sauce)
• 2 ½ cups chicken broth (the flavorful foundation of our sauce)
• 1/2 cup milk or heavy cream (for richness and creaminess)
• 1 teaspoon dried thyme (adds that classic herby note)
• 1 teaspoon onion powder (a little flavor booster)
• Salt and black pepper to taste (don’t be shy!)
• 1 can (8 oz) refrigerated crescent roll dough or 1 tube of biscuit dough (our easy, flaky topping)

Let’s Get Cooking Step by Step

1. Preheat your oven to 375°F (190°C) and grab a 9×13 inch baking dish. Lightly grease it with a little butter or cooking spray.
2. Heat the olive oil in a large skillet or Dutch oven over medium heat. Add the diced onion and cook for about 4-5 minutes, until it becomes soft and translucent. Add the garlic and cook for one more minute, until it’s fragrant.
3. Stir in your mixed vegetables. If you’re using frozen, no need to thaw them first! Cook everything together for another 3-4 minutes.
4. Sprinkle the flour over the vegetable mixture. Stir constantly for about a minute to cook the raw flour taste out. This is our thickening trick!
5. Slowly pour in the chicken broth and milk, stirring continuously. Bring the mixture to a gentle simmer. Keep stirring until the sauce thickens beautifully, which should take about 3-5 minutes.
6. Take the skillet off the heat. Stir in your cooked chicken, dried thyme, onion powder, and a good amount of salt and pepper. Give it a taste and adjust the seasoning if needed. Pour this creamy filling into your prepared baking dish.
7. Unroll the crescent roll or biscuit dough. You can place the sheets right on top for a full crust, or for a more rustic look, tear the dough into pieces and scatter them over the filling.
8. Pop the dish into the preheated oven and bake for 20-25 minutes, or until the filling is bubbly around the edges and the dough topping is puffed up and a deep golden brown.
9. Let the casserole sit for about 5-10 minutes after pulling it from the oven before serving. This helps the filling set so it’s not too runny. So good.

Classic Chicken Pot Pie Casserole Tips For Success

• Don’t skip the step of cooking the flour with the veggies. It makes all the difference for a gravy that’s not pasty.
• For the most flavor, use a good quality chicken broth. It’s the base of your sauce!
• If your filling seems too thick after adding the broth and milk, you can add a splash more broth to thin it to your liking.
• Letting the casserole rest for a few minutes after baking is a game-changer for clean slices.
• For extra browning and crispiness on top, you can brush the dough with an egg wash before baking.
• And remember, a few spills in the kitchen just mean you’re having fun!

Creative Variations & Substitutions

This recipe is wonderfully flexible. Short on time? Use a bag of frozen mixed vegetables and a rotisserie chicken. Want to lighten it up? Swap the cream for whole milk and use a low-sodium broth. For a gluten-free version, a 1:1 gluten-free flour blend works perfectly as a thickener, and you can top it with your favorite gluten-free biscuits. Feel free to play with the veggies, too—corn, chopped broccoli, or even some sliced mushrooms would be delicious. If you’re out of crescent rolls, a layer of mashed potatoes makes for a fantastic shepherd’s pie-style topping.

Serving Ideas & Pairings

This casserole is a complete meal all on its own, truly one of the easiest dinner dishes you can make. But if you’re looking to round out the table, a simple green salad with a bright vinaigrette is perfect for cutting through the richness. For something a bit heartier, some quick buttermilk biscuits or a crusty loaf of bread are ideal for soaking up every last bit of that creamy sauce. It’s the ultimate comfort food that fits right into your rotation of easy weeknight dinners.

Storage & Reheating Instructions

Leftovers? They store beautifully! Let the casserole cool completely, then cover the baking dish tightly with plastic wrap or transfer portions to airtight containers. It will keep in the fridge for up to 4 days. To reheat, the microwave is quick for a single portion (about 2-3 minutes on high), but for the best results, pop it in the oven at 350°F until warmed through. This helps the biscuit topping stay crisp. You can also freeze this casserole for up to 3 months. Thaw it overnight in the refrigerator before reheating.

Frequently Asked Questions

• Can I make this Classic Chicken Pot Pie Casserole ahead of time? Absolutely! You can assemble the filling and pour it into the dish a day ahead. Keep it covered in the fridge. When you’re ready to bake, just add the biscuit topping and pop it in the oven. You might need to add a few extra minutes to the baking time since it’s starting cold.
• What are some other cheap dinners for a family that are similar? This casserole is a great budget-friendly option! Other ideas include a hearty chili, a simple baked pasta like ziti, or a big pot of soup and cornbread.
• I need healthy dinner ideas. How can I make this lighter? You sure can! Use a low-fat milk instead of cream, load up on extra vegetables, and opt for a low-sodium broth. Using a whole-wheat biscuit dough on top can add fiber, too.
• What’s the best way to get a crispy topping? Make sure your oven is fully preheated and that the rack is in the center position. Giving the dough a little space to breathe (not cramming it all together) also helps it get nice and crispy rather than steaming.
