It’s become a staple in my house for snow days, Sunday suppers, and anytime I want a hug on a plate.

What Ingredients You Will Need

This Cheddar Bay Chicken Pot Pie Casserole uses everyday ingredients that come together for a rich and comforting dinner. Here’s what you’ll need, grouped by their role in the recipe:

For the Creamy Chicken Filling:

• Cooked Chicken (3 cups / about 400g, shredded or diced) – Rotisserie chicken works perfectly for convenience and flavor.
• Mixed Frozen Vegetables (2 cups / 300g) – Usually a blend of peas, carrots, corn, and green beans. Fresh veggies work too; just dice small and par-cook first.
• Unsalted Butter (4 tbsp / 56g) – For sautéing and creating a rich base.
• All-Purpose Flour (1/3 cup / 40g) – Helps thicken the filling.
• Chicken Broth (2 cups / 480ml) – I like using low-sodium to control the saltiness.
• Heavy Cream (1/2 cup / 120ml) – Makes the filling extra luscious (you can sub with half-and-half or milk for a lighter version).
• Onion (1 small, finely chopped) – Adds sweetness and depth.
• Garlic (2 cloves, minced) – For that little pop of flavor.
• Salt & Pepper (to taste) – Start with 1/2 tsp salt and 1/4 tsp pepper.
• Poultry Seasoning (1 tsp) – Classic pot pie flavor. Substitute with thyme and sage if you don’t have it.

For the Cheddar Bay Biscuit Topping:

• Cheddar Bay Biscuit Mix (1 box, about 11 oz / 312g) – I usually grab Red Lobster brand, but any cheddar biscuit mix works.
• Sharp Cheddar Cheese (1 cup / 115g, shredded) – The sharper, the better for extra cheesy flavor.
• Milk (2/3 cup / 160ml) – For mixing the biscuit dough.
• Unsalted Butter (1/4 cup / 56g, melted) – For brushing on top (and mixing into the dough).
• Garlic Powder (1/2 tsp) – For that signature garlic kick in the biscuits.
• Fresh Parsley (2 tbsp, chopped, optional) – For color and a hint of freshness.

Ingredient Tips & Substitutions:

• For a gluten-free version, use gluten-free biscuit mix and flour (I’ve had good luck with King Arthur’s blend).
• If you’re dairy-free, swap in plant-based butter, non-dairy milk, and a vegan cheese alternative. Biscuit texture will be slightly different but still tasty.
• Don’t have rotisserie chicken? Poach or roast chicken breasts/thighs, or use leftover turkey!
• Love extra veggies? Stir in a handful of baby spinach or mushrooms before baking.

Equipment Needed

• Large Skillet or Sauté Pan – For making the chicken and veggie filling. I like a nonstick or enameled cast iron pan for easy cleanup.
• Mixing Bowl – For stirring together the biscuit topping.
• Whisk – Helps prevent lumps in the creamy sauce.
• Measuring Cups & Spoons – Accuracy makes all the difference, especially with baking.
• 9×13-inch Baking Dish (23x33cm) – My go-to for casseroles. Glass or ceramic both work well.
• Rubber Spatula or Wooden Spoon – For spreading the filling and topping evenly.
• Pastry Brush (optional) – For brushing melted butter over the biscuits before and after baking. If you don’t have one, use the back of a spoon.

If you don’t have a 9×13-inch dish, two smaller baking dishes will work—just keep an eye on the baking time. I’ve even used a deep pie dish in a pinch when I want extra biscuit crust around the edges! For easy cleanup, lightly spray your baking dish with nonstick spray before assembling. And for the budget-minded, most of these tools are basics you’ll use again and again—no need to buy anything fancy. My battered old skillet has survived hundreds of casseroles and still gets the job done just fine!

How to Make Cheddar Bay Chicken Pot Pie Casserole

1. Preheat your oven to 400°F (200°C). This helps the biscuit topping bake up fluffy and golden. Don’t skip this step—cold oven = sad biscuits!
2. Prepare the Creamy Chicken Filling:
   – In a large skillet over medium heat, melt 4 tbsp (56g) unsalted butter.
   – Add the chopped onion and cook for 2-3 minutes, until translucent and fragrant.
   – Stir in 2 cloves minced garlic and sauté for 30 seconds.
   – Sprinkle in 1/3 cup (40g) flour and stir constantly for 1 minute to cook off the raw flour taste—it’ll look a bit pasty.
   – Gradually whisk in 2 cups (480ml) chicken broth until the mixture is smooth and starts to thicken.
   – Add 1/2 cup (120ml) heavy cream, 1 tsp poultry seasoning, 1/2 tsp salt, and 1/4 tsp black pepper. Stir well.
   – Mix in 3 cups (400g) shredded chicken and 2 cups (300g) frozen mixed veggies.
   – Let it simmer for 2-3 minutes, until everything’s combined and the veggies are just tender. If too thick, add a splash of broth. If too thin, simmer a bit longer.
3. Assemble the Casserole:
   – Pour the hot filling into a greased 9×13-inch (23x33cm) baking dish and spread evenly.
   – If you like a crispier bottom, you can pre-bake the dish for 5 minutes before adding the topping.
4. Mix the Cheddar Bay Biscuit Topping:
   – In a large bowl, combine 1 box (312g) Cheddar Bay biscuit mix, 1 cup (115g) shredded cheddar, and 1/2 tsp garlic powder.
   – Stir in 2/3 cup (160ml) milk and 1/4 cup (56g) melted butter until just mixed. Don’t overwork it—lumpy is good.
   – Drop large spoonfuls of the dough evenly over the filling (it’s okay if some filling peeks through).
5. Bake the Casserole:
   – Place in the oven and bake for 25-30 minutes, until the biscuit topping is golden brown and a toothpick comes out clean.
   – If the biscuits brown too quickly, loosely tent with foil for the last 10 minutes.
6. Butter & Garnish:
   – As soon as it comes out, brush the biscuits with a little extra melted butter, and sprinkle with chopped fresh parsley if you like.
7. Cool Slightly & Serve:
   – Let the casserole sit for 5-10 minutes (trust me, it’ll be lava hot inside).
   – Scoop into generous portions and enjoy!

Preparation Tips: If your filling seems too runny, let it bubble on the stove a bit longer to thicken up. For super fluffy biscuits, avoid over-mixing the dough and always preheat your oven fully. And if you’re prepping ahead, you can make the filling a day in advance and store in the fridge—just add a few extra minutes to the bake time when assembling from cold.

Cooking Tips & Techniques

• Don’t Overmix the Biscuit Dough: Just stir until combined—some lumps are totally fine! Overworking the dough makes the topping tough instead of tender and fluffy.
• Keep the Filling Hot: Pouring hot filling into the baking dish helps the biscuit topping cook evenly and rise beautifully. Cold filling can lead to soggy bottoms (never fun).
• Check Biscuit Doneness: The biscuits should be golden on top and cooked through in the center. If you’re unsure, insert a toothpick—it should come out clean with a few crumbs.
• Troubleshooting Thin Filling: If your filling looks watery after baking, let the casserole rest uncovered for 10-15 minutes. It thickens up as it cools.
• Multi-Task Like a Pro: While the filling simmers, prep your biscuit mix and melt your butter. This saves time and makes the process feel way less hectic.
• Personal Lessons: The first time I made this, I got impatient and didn’t let it cool before serving—cue the molten cheese burn! Give it a few minutes to set up for best results.
• For Extra Crispy Topping: If you crave more crunch, broil the casserole for 1-2 minutes at the end (just keep a close eye on it!).

Honestly, this recipe is pretty forgiving, but the biggest mistake is not letting it rest after baking. It’s tempting to dig in right away, but a little patience makes the flavors meld and the texture just right. Every time I’ve rushed it, I end up with a runny mess—so trust me on that cool-down time!

Variations & Adaptations

• Low-Carb/Keto: Swap out the biscuit mix for a low-carb baking blend and use almond flour with extra cheese. The topping will be slightly denser but still super flavorful.
• Gluten-Free: Use a gluten-free biscuit mix and gluten-free flour for the filling. I’ve done this for friends with celiac and it’s just as comforting.
• Vegetarian: Substitute the chicken with canned chickpeas or sautéed mushrooms, and use vegetable broth. The filling is hearty enough to stand on its own!
• Seasonal Swaps: In late summer, add diced zucchini or fresh corn. In winter, roast a handful of butternut squash cubes and fold them in.
• Spicy Kick: Stir a little cayenne or hot sauce into the filling for some heat. My husband loves it this way!
• Dairy-Free: Use plant-based butter, non-dairy milk, and a vegan cheese. The texture changes a bit, but it’s still delicious and golden.

One of my favorite personal twists was using leftover Thanksgiving turkey and adding a handful of sautéed leeks—seriously, it was next-level autumn comfort food. Don’t be afraid to riff on this Cheddar Bay Chicken Pot Pie Casserole with whatever you have on hand. The method is really adaptable, and you’ll end up with a dish that fits your own taste perfectly.

Serving & Storage Suggestions

This Cheddar Bay Chicken Pot Pie Casserole is best served hot, straight from the oven. The biscuits are at their fluffiest, and the filling is perfectly creamy (but not scalding, if you let it rest a bit!).

• Serving: Scoop generous portions into wide bowls or onto plates. I love sprinkling extra fresh parsley or cracked black pepper on top for a pop of color.
• Pairings: Serve with a simple green salad and a crisp white wine or sparkling apple cider for a cozy dinner combo. Crusty bread is optional, but if you’re anything like me, you won’t need it with all that biscuit goodness.
• Storing Leftovers: Let the casserole cool completely, then cover tightly and refrigerate for up to 4 days. For longer storage, portion into airtight containers and freeze for up to 2 months.
• Reheating: Warm individual servings in the microwave for 2-3 minutes or reheat the whole casserole in a 350°F (175°C) oven until bubbly (about 20-25 minutes). If you’re reheating from frozen, thaw in the fridge overnight first.

Fun tip: The flavors actually get even better the next day as everything melds together. If you notice the biscuits have softened up, pop leftovers under the broiler for a minute to crisp them back up—works like a charm!
