Ingredients Equipment Method

Ingredients

  

• 4 cups mixed fall vegetables (such as butternut squash, carrots, parsnips, and sweet potatoes) peeled and chopped into bite-sized pieces
• 2 tablespoons olive oil
• 1 teaspoon fresh sage, chopped
• 1 teaspoon fresh thyme leaves
• 1 large onion sliced thin
• 1.5 pounds chicken thighs or breasts bone-in or boneless, skinless
• Salt and black pepper to taste

Equipment

• Baking dish or casserole pan
• Sharp knife
• Cutting board
• Mixing bowl
• Spoon or spatula

Method

 

1. Preheat your oven to 400°F (200°C). Toss the chopped fall vegetables and sliced onions with olive oil, chopped sage, thyme, salt, and pepper in a large mixing bowl until evenly coated.
2. Spread the seasoned vegetables in an even layer in your baking dish or casserole pan. Place the dish in the oven and roast for 20 minutes until the vegetables start to soften and caramelize around the edges.
3. Meanwhile, season the chicken thighs or breasts with salt and pepper. Heat a skillet over medium-high heat and sear the chicken for 3-4 minutes per side until browned, then set aside.
4. Remove the roasted vegetables from the oven and nestle the seared chicken pieces among them. Return the dish to the oven and roast for an additional 20-25 minutes, until the chicken is cooked through and the vegetables are tender and caramelized.
5. Once cooked, transfer the casserole to a serving platter. Let it rest for a few minutes, allowing the juices to settle, then garnish with extra sage if desired.
6. Serve warm, enjoying the tender chicken coated in the flavorful roasted vegetables and herbs, with a golden, crispy top.

In these busy months, having a dish like this on hand is a small victory. It’s reliable, hearty, and perfect for making ahead; just pop it in the oven and forget about it until dinner. As the season changes, this casserole becomes a reminder of home, comfort, and the simple joy of good food shared around the table.

There’s something grounding about a homemade casserole when outside it’s brisk and briskly changing. It’s a dish that takes care of you, a quiet celebration of fall’s best ingredients and cozy moments.
