How to Make Easy Harvest Chicken Casserole

Step 1: Prepare the Vegetables

Preheat your oven to 375°F (190°C). In a 9×13-inch baking dish, combine sweet potatoes, Brussels sprouts, diced onion, and minced garlic. Sprinkle with smoked paprika, cumin, salt, and pepper. Drizzle with half of the avocado oil and toss well to coat evenly.

Step 2: Bake the Vegetables

Pour chicken broth into the dish to keep everything moist. Cover tightly with foil and bake for 22–25 minutes, or until the vegetables are fork-tender.

Step 3: Sear the Chicken

While the vegetables are baking, heat the remaining avocado oil in a large skillet over medium-high heat. Add the chicken pieces, season with salt and pepper, and sear for 3–4 minutes until lightly golden and almost cooked through.

Step 4: Combine and Assemble

Remove the baking dish from the oven. Stir in the seared chicken and dried cranberries, distributing everything evenly.

Step 5: Add Cheese and Finish Baking

Sprinkle shredded cheddar cheese over the top. Return the dish to the oven uncovered and bake for an additional 10–12 minutes, until the chicken is fully cooked and the cheese is melted and bubbly.

Step 6: Garnish and Serve

Remove from the oven and let it rest for a few minutes. Add optional toppings like green onions, pumpkin seeds, or parsley before serving.

Tips for Success

• Cut vegetables into even sizes for consistent cooking
• Covering with foil ensures vegetables become tender
• Don’t overcook the chicken during searing—it will finish in the oven
• Add cheese at the end to prevent over-browning
• Taste and adjust seasoning before final bake if needed

Equipment Needed

• 9×13-inch baking dish
• Large skillet
• Cutting board and knife
