Ingredients

2 tbsp butter

1 small onion, diced

2 cloves garlic, minced

2 cups cooked chicken, shredded or diced (rotisserie, leftover, or canned)

2 cups frozen mixed vegetables (peas, carrots, corn)

1 can (10.5 oz) cream of chicken soup (or substitute cream of mushroom/celery or thick gravy)

1/2 cup milk (any kind)

1/2 tsp salt

1/2 tsp black pepper

1/2 tsp dried thyme (optional)

1/4 tsp poultry seasoning (optional)

1 can refrigerated biscuit dough or 1 sheet puff pastry

Optional: 1 egg or milk for egg wash

Instructions

Step 1: Preheat the oven to 375°F (190°C) and grease a 9×13-inch casserole dish.

Step 2: Melt butter in a skillet over medium heat. Cook the diced onion for 3–4 minutes until translucent, then add minced garlic and cook for 1 more minute.

Step 3: Stir in the cooked chicken, frozen mixed vegetables, cream of chicken soup, milk, salt, pepper, thyme, and poultry seasoning if using. Simmer for 5 minutes until the filling thickens slightly. Taste and adjust seasonings as needed.

Step 4: Pour the filling into the prepared casserole dish, spreading it out evenly.

Step 5: Arrange the biscuit dough on top either whole or quartered for more coverage, or cover with puff pastry. Brush the top with egg wash or milk if desired for a golden finish.

Step 6: Bake for 25–30 minutes, until the filling is bubbly and the topping is golden brown. Let the casserole rest for 5 minutes before serving.

Tips & Variations

For a cheesier twist, stir in 1 cup shredded cheddar cheese into the filling before assembling.

Sprinkle Everything Bagel Seasoning on top of the biscuits for a flavorful crunch.

Add extra veggies like broccoli or spinach to boost nutrition and color.

Use turkey instead of chicken for a post-holiday leftover makeover.

If the filling is too runny, simmer longer or thicken with 1 tbsp cornstarch mixed with 2 tbsp cold milk or water.

For even biscuit cooking, use warm filling and cut biscuits into smaller pieces.

No skillet? Sauté onions and garlic in a saucepan or pot before combining other ingredients.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through. To make ahead, assemble the casserole up to 24 hours in advance and refrigerate, adding 5–10 minutes to baking time. For longer storage, freeze the unbaked casserole tightly wrapped for up to 3 months; bake from frozen, increasing baking time by 15–25 minutes.

FAQs

Can I use fresh vegetables instead of frozen?

Yes, fresh vegetables work well. Just chop them into bite-sized pieces and cook slightly before adding to the filling to ensure they soften during baking.

What’s the best topping: biscuits or puff pastry?

Both toppings are delicious. Biscuits create a soft, fluffy crust, while puff pastry offers a flaky, buttery texture. Choose based on your preference or what you have on hand.
