Step‑by‑Step Instructions for Harvest Chicken Casserole Recipe
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms, grease a 9″x13″ baking dish with olive oil to ensure your Harvest Chicken Casserole doesn’t stick. This preparation will make it easier to serve later, allowing all those comforting flavors to meld beautifully together.
Step 2: Sear the Chicken
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Season the boneless, skinless chicken breasts with salt and pepper, then add them to the pan. Sear the chicken for about 8 minutes on each side until golden brown. Remove the chicken from the heat and let it rest for 10 minutes before cutting it into 1-inch chunks.
Step 3: Sauté the Vegetables
In the same skillet, add another tablespoon of olive oil and toss in the chopped onion, sweet potatoes, and Brussels sprouts. Sauté these vegetables for around 5 minutes, adding minced garlic, thyme, paprika, and cumin. Season with salt and pepper, then pour in 1/4 cup of chicken broth. Cover the skillet and let it simmer for an additional 5 minutes, allowing the veggies to soften.
Step 4: Assemble the Casserole
Layer the bottom of the greased baking dish with cooked wild rice, spreading it out evenly. Next, add the seared chicken chunks, followed by the sautéed vegetable mixture and dried cranberries. Pour in the remaining chicken broth to keep the casserole moist, then sprinkle the sliced almonds on top for that satisfying crunch.
Step 5: Bake to Perfection
Carefully place the baking dish in the preheated oven and bake for 15-18 minutes. Keep an eye on the casserole, ensuring it’s heated through and the almonds turn a lovely golden color. You’ll know it’s ready when you see bubbling edges and a delicious aroma fills your kitchen, signaling that your Harvest Chicken Casserole is a comforting meal waiting to be enjoyed.
