Instructions
- Prepare the Chicken: Begin by preheating your oven to 375°F (190°C). While the oven is heating, prepare the chicken. If using large chicken breasts, you may want to cut them into smaller, bite-sized pieces or strips. This will ensure they cook evenly and are easier to incorporate into the casserole. Season the chicken pieces generously with salt and black pepper. Don’t be shy with the seasoning – it’s crucial for flavorful chicken in the final dish.
- Sauté the Vegetables: In a large oven-safe skillet or Dutch oven, heat olive oil over medium heat. Once the oil is shimmering, add the chopped yellow onion, celery, and carrots. Sauté these vegetables for about 5-7 minutes, or until they begin to soften and the onions become translucent. Stir them occasionally to prevent sticking and ensure even cooking. Sautéing these vegetables first is key to developing their flavors and softening them before baking.
- Add Garlic and Herbs: Add the minced garlic to the skillet with the sautéed vegetables and cook for another minute, until fragrant. Be careful not to burn the garlic, as it can become bitter. Stir in the dried thyme and dried rosemary, allowing the herbs to bloom in the heat and release their aromatic oils. This step infuses the vegetable base with a wonderful savory fragrance.
- Cook the Chicken: Add the seasoned chicken pieces to the skillet with the vegetables. Cook the chicken until it is browned on all sides but not fully cooked through. It will finish cooking in the oven. Browning the chicken adds another layer of flavor and texture to the casserole.
- Prepare the Sauce: In a separate medium-sized saucepan, melt butter over medium heat. Whisk in the all-purpose flour and cook for about 1 minute, stirring constantly, to create a roux. This will help thicken the sauce. Gradually whisk in the chicken broth, ensuring there are no lumps. Continue whisking until the sauce thickens slightly. Slowly pour in the heavy cream, stirring continuously until the sauce is smooth and creamy. Season the sauce with salt and black pepper to taste. Taste and adjust the seasoning as needed – the sauce should be flavorful enough to complement the other ingredients.
- Assemble the Casserole: Pour the creamy sauce over the chicken and vegetables in the skillet. Stir gently to combine everything evenly, ensuring the chicken and vegetables are coated in the sauce. Add the frozen peas to the mixture. Stir them in gently, distributing them throughout the casserole.
- Add Sweet Potatoes: Arrange the sweet potato slices evenly over the top of the chicken and vegetable mixture. You can create a decorative pattern if desired, or simply layer them in a single layer covering the surface. The sweet potatoes will bake and soften on top of the creamy chicken mixture.
- Top with Cheese: Sprinkle the shredded cheddar cheese generously over the sweet potato slices. Ensure the cheese is evenly distributed to create a nice, cheesy crust when baked.
- Bake the Casserole: Place the skillet or Dutch oven in the preheated oven and bake for 30-40 minutes, or until the sweet potatoes are tender when pierced with a fork and the cheese is melted and golden brown. The casserole should be bubbly and heated through.
- Rest and Serve: Remove the casserole from the oven and let it rest for about 5-10 minutes before serving. This allows the casserole to set slightly and the flavors to meld together. Garnish with fresh parsley, if desired, for a pop of color and freshness. Serve hot and enjoy!
