  • 2 cups chicken, cubed: Use fresh chicken breast or thigh pieces for tender, juicy results.
  • 1 large sweet potato, cubed: Choose firm, brightly colored sweet potatoes for natural sweetness and creamy texture.
  • 1 cup Brussels sprouts, halved: Adds a slightly nutty flavor and a satisfying bite, balancing the sweet potato perfectly.
  • ¼ cup dried cranberries: Gives a burst of tartness to brighten the dish and complement the savory ingredients.
  • ½ cup chicken broth: Keeps the casserole moist and infuses a rich, savory background flavor.
  • 1 tsp rosemary: Fresh or dried, rosemary offers an earthy, pine-like aroma that embodies autumn.
  • ½ cup shredded cheese (optional): A creamy, melty topping that adds richness and a delightful golden crust.

How to Make Harvest Chicken Casserole with Sweet Potatoes Recipe

Step 1: Prepare Your Ingredients

Start by cubing the chicken and sweet potatoes into bite-sized pieces. Halve the Brussels sprouts to ensure they cook evenly and soften beautifully without losing their bright color. Having everything prepped before assembling makes the process smooth and enjoyable.

Step 2: Combine Everything in a Baking Dish

In a suitable casserole or baking dish, mix together the cubed chicken, sweet potatoes, halved Brussels sprouts, and dried cranberries. Sprinkle the rosemary evenly on top and pour in the chicken broth to keep everything moist and flavorful during baking. This simple step sets the foundation for all those lovely mingling flavors.

Step 3: Bake at 375°F for 30–35 Minutes

Place the dish into a preheated oven at 375°F. Bake uncovered, allowing the sweet potatoes to soften and the chicken to cook through while the Brussels sprouts roast to slight caramelization. The combination of heat and time lets the cranberries plump up slightly, adding a juicy contrast.

Step 4: Add Cheese and Finish Baking

If you’re using cheese, sprinkle it over the top after the initial bake. Return the casserole to the oven for an additional 5 minutes to melt the cheese into a golden, bubbly topping that adds richness and a welcoming gooey texture.

Garnishes

For a final touch, try sprinkling toasted pecans or walnuts atop your casserole just before serving. This adds a lovely warm crunch that contrasts with the softness of the chicken and sweet potatoes, elevating the dish beautifully.

Side Dishes

This casserole is deliciously hearty on its own, but pairing it with a crisp green salad or some steamed green beans provides refreshing brightness and textural variety to your meal. A warm crusty bread also complements the casserole wonderfully for sopping up any tasty juices.

Creative Ways to Present

When serving, present the casserole in individual ramekins for a charming, personalized touch that’s perfect for dinner parties or cozy family meals. Alternatively, serve it family-style straight from the baking dish for a warm, inviting centerpiece that encourages shared enjoyment.

Make Ahead and Storage

Storing Leftovers

Once cooled, store any leftovers in an airtight container in the refrigerator. The flavors continue to deepen, making it even more delicious the next day. Leftovers will keep fresh for up to 3 days.

Freezing

This Harvest Chicken Casserole with Sweet Potatoes Recipe freezes beautifully. Place cooled portions in freezer-safe containers or bags, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating to maintain texture and flavor.

Reheating

Reheat the casserole gently in the oven at 350°F until warmed through, about 15-20 minutes, or microwave individual portions for a quicker option. Adding a little extra cheese on top before reheating can revive the casserole’s signature gooey goodness.

FAQs

Can I use frozen vegetables in this casserole?

Frozen Brussels sprouts and sweet potatoes can work in a pinch, but fresh ingredients provide better texture and flavor. If using frozen, thaw and drain excess moisture before adding to avoid a soggy casserole.

Is it possible to make this dish dairy-free?

Absolutely! Simply skip the cheese or use your favorite dairy-free cheese alternative for a delicious dairy-free version of this casserole without compromising taste.

Can I substitute the chicken with turkey or another protein?

Yes, turkey makes a great substitute and complements the autumn flavors well. You can also try tofu or chickpeas for a vegetarian twist, though cook times may vary.

How spicy is this casserole? Can I add more seasoning?

This recipe is mild, focusing on warm, savory, and slightly sweet autumn flavors. Feel free to add a pinch of cayenne or smoked paprika if you like a bit of heat and complexity.

What is the best way to prepare the sweet potatoes for this recipe?

Peeling the sweet potatoes is optional but recommended for a smoother texture. Cutting them into uniform cubes ensures even cooking and perfect tenderness when baked.
