Cooking Instructions

  1. 1

    Prepare the Ingredients

    Preheat your oven to 375°F (190°C). Peel and cut the Yukon Gold potatoes into chunks. Slice the fennel and onions. Clean and slice the mushrooms.

  2. 2

    Cook the Chicken

    In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Season the chicken breasts with salt and pepper, then grill them for about 5-7 minutes on each side, until they are golden brown. Remove from the skillet and set aside.

  3. 3

    Caramelize the Onions and Cook the Vegetables

    In the same skillet, add another tablespoon of olive oil. Add the sliced onions and fennel, and cook until caramelized, about 10-15 minutes. Add the mushrooms and cook for an additional 5 minutes.

  4. 4

    Roast Garlic

    Wrap the garlic head in foil with a drizzle of olive oil and roast in the oven for 30 minutes until soft.

  5. 5

    Assemble the Casserole

    In a large baking dish, layer the potatoes at the bottom. Top with the caramelized onion, fennel, and mushroom mixture. Place the grilled chicken on top and drizzle with chicken broth. Squeeze roasted garlic over everything for flavor.

  6. 6

    Bake

    Cover the baking dish with foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for an additional 15 minutes, or until the potatoes are tender and the chicken is cooked through.

  7. 7

    Serve

    Let the casserole cool for a few minutes before serving. Garnish with fresh thyme if desired.
