Leftover Turkey and Biscuit Casserole Ingredients
To make this recipe, we will need the following ingredients:
- 2 cups cooked turkey, shredded or diced — adds protein, heartiness, and richness; shredding gives a creamier texture while diced pieces give chunkier bites.
- 2 cups frozen mixed vegetables — bring color, sweetness, nutrients, and texture; the mix of peas, carrots, corn, and green beans keeps the casserole balanced and hearty.
- 1 (10.5-oz) can cream of chicken soup — acts as the creamy, savory base that ties all ingredients together; adds salt, umami, and thickness.
- ½ cup milk — thins the soup slightly to create a smooth, pourable sauce; adds mild creaminess without making the dish heavy.
- 2 tablespoons melted butter — boosts richness, enhances flavor, and helps soften and coat the veggies and turkey.
- 1½ cups shredded cheddar cheese (1 cup in the filling, ½ cup on top) — adds melty, savory, cheesy comfort; the top layer creates a golden, gooey crust, while the filling layer makes the casserole creamy.
- 1 can Grands biscuits (8-count) — provides a fluffy, buttery, satisfying bread topping that puffs up and turns golden, giving pot-pie vibes without making a crust from scratch.
- Salt & pepper to taste — essential for balancing the creaminess and enhancing the flavor of the turkey and vegetables.
- Optional: garlic powder, onion powder, dried thyme, paprika — deepen the flavor: garlic and onion powder add savory warmth, thyme adds herbal depth, and paprika adds color and a subtle smoky note.
Steps to Make Leftover Turkey and Biscuit Casserole
Once youve gathered your ingredients, we will use the following recipe:
Mix Turkey, Vegetables, and Soup
Mix together shredded turkey, a can of soup, and vegetables.
Mix in Cheese
Add shredded cheese, mix well.
Top with Biscuits
Add to a greased casserole dish or skillet. Rip biscuits up and place on top of turkey and soup base.
Bake
Bake at 350F, covered for 20 minutes (with foil or a lid) and 20-30 minutes uncovered, until casserole is bubbly hot and biscuit dough is golden brown.
Tips and Tricks to Perfect Leftover Turkey and Biscuit Casserole
Cut the biscuits into quarters so they bake through fully—whole biscuits often stay doughy in the middle.
Use freshly shredded cheddar if possible; it melts smoother and creamier than bagged shredded cheese.
Warm the milk slightly before mixing with the cream of chicken soup for a smoother sauce.
Season the filling well before adding the biscuits—the biscuit topping can mellow flavors, so make sure the base tastes great first.
Add a pinch of garlic powder, onion powder, and thyme even if you don’t usually season casseroles—these boost savory depth fast.
Let the frozen veggies thaw for 10–15 minutes or rinse under cool water to remove excess ice so the casserole doesn’t get watery.
Stir some cheese into the filling and some on top for the best texture—creamy inside, golden outside.
Brush the biscuits with a little melted butter before baking to help them brown beautifully.
Bake on the lower-middle rack so the biscuits brown without the bottom overcooking.
Cover with foil if biscuits brown too quickly—this keeps the top golden without burning.
Let the casserole rest 5 minutes before serving so the filling thickens and scoops cleanly.
Swap Grands for flaky-layer biscuits if you prefer pull-apart, buttery layers.
Add a handful of cooked bacon or ham for even more depth and smokiness.
Don’t skip the pepper—the creamy base needs that sharpness to stay balanced.
Serve with a simple side salad or roasted veggies to balance the richness of the casserole.
FAQs for Turkey Biscuit Casserole
Yes—rotisserie chicken or leftover chicken works perfectly and tastes just as good.
It’s not required, but partially thawing them or rinsing off the ice helps prevent extra moisture in the casserole.
Absolutely. Cream of mushroom, cream of celery, or cream of turkey all work well.
Yes—flaky-layer biscuits, homemade biscuit dough, or even puff pastry can be used instead.
They were likely too large. Quartering the biscuits helps them bake through evenly. You can also bake an extra 5–10 minutes if needed.
Yes—corn, green beans, peas, sautéed mushrooms, or even broccoli florets work great.
You can assemble the filling ahead, but add the biscuits right before baking so they stay crisp and rise properly.
The filling freezes beautifully, but the biscuits do not. Freeze just the filling and top with biscuits when baking fresh.
Definitely—add extra cheddar to the filling or sprinkle a full cup on top for a cheesier finish.
A 9×13 casserole dish is ideal, but any similar-size baking dish works fine.
Use low-fat milk, reduced-fat soup, and half the cheese. You can also top with fewer biscuit pieces.
Add paprika, crushed red pepper, diced jalapeños, or use pepper jack cheese.
