Ingredients Overview

Bone-In, Skin-On Chicken Thighs
Juicy, flavorful, and perfect for roasting. The skin crisps beautifully, and the bone keeps the meat tender. You can also use drumsticks or boneless thighs if you prefer, adjusting the cook time slightly.

Yukon Gold or Baby Potatoes
Creamy, buttery potatoes hold their shape well and soak up the sauce like a sponge. Halve or quarter them depending on size.

Mushrooms
Cremini or white button mushrooms add an earthy, umami-rich depth to the dish. Slice thick for hearty bites that hold up during roasting.

Fresh Herbs
A mix of rosemary, thyme, and parsley brings rustic, woodsy flavor. Use fresh if possible, but dried herbs work too in smaller amounts.

Garlic & Onion
Roasted garlic and caramelized onion form the aromatic base of the dish. They infuse the sauce and vegetables with savory sweetness.

Heavy Cream or Half-and-Half
The creamy white sauce starts with a splash of cream for richness. You can substitute with whole milk or dairy-free options, but the texture may be thinner.

Chicken Broth
Adds savory depth and thins the sauce just enough to coat everything evenly.

Butter & Olive Oil
Used to sear the chicken and sauté the vegetables. Adds richness and helps brown the chicken skin to perfection.

Salt & Pepper
Season generously throughout the layers of the dish to bring out the full flavor of each ingredient.

Step-by-Step Instructions

1. Preheat the Oven
   Set your oven to 400°F (200°C). Lightly grease a large cast iron skillet or oven-safe baking dish.
2. Sear the Chicken
   Pat 4–6 bone-in, skin-on chicken thighs dry. Season both sides with salt, pepper, and a pinch of rosemary and thyme.
   In a large skillet over medium-high heat, add 1 tbsp olive oil and 1 tbsp butter. Sear the chicken skin-side down for 4–5 minutes until golden and crispy. Flip and sear the other side for 2 minutes. Remove and set aside.
3. Sauté Vegetables
   In the same pan, add:

• 1 sliced onion
• 3 cloves garlic, minced
• 8 oz mushrooms, thickly sliced

Sauté for 4–5 minutes until the onions soften and mushrooms begin to brown.

4. Add Potatoes and Sauce Base
   Add 1½ lbs baby or Yukon gold potatoes, halved or quartered. Pour in:

• ½ cup chicken broth
• ¾ cup heavy cream
• A small handful of chopped fresh herbs (or 1 tsp each dried rosemary and thyme)

Stir gently to coat everything. Season with salt and pepper to taste.

5. Assemble and Roast
   Nestle the seared chicken thighs back into the pan, skin-side up. Spoon some sauce over the top of the vegetables. Transfer the entire skillet to the oven and roast uncovered for 30–35 minutes, or until the chicken is cooked through (internal temp 165°F) and the potatoes are fork-tender.
6. Rest and Serve
   Let rest for 5 minutes before serving. Garnish with fresh parsley and a splash of lemon juice or cracked pepper, if desired.

Tips, Variations & Substitutions

Use Boneless Chicken
Boneless, skinless thighs or breasts will work — reduce roasting time by about 10 minutes. Be careful not to dry them out.

Add Greens
Stir in spinach or kale in the last 5 minutes of baking for a pop of color and extra nutrition.

Make It Dairy-Free
Use unsweetened oat or almond milk and olive oil instead of cream and butter. Add a spoonful of dairy-free cream cheese for richness.

Make It a Casserole
Shred the chicken after cooking and mix everything together before returning to the oven with a topping of breadcrumbs or cheese.

More Flavor Boosts
Add a splash of white wine with the broth, or a pinch of smoked paprika or nutmeg in the cream sauce.

Use Leftovers
Leftover chicken, potatoes, and sauce make an excellent filling for savory hand pies, pot pies, or a next-day hash.

FAQs

1. Can I use chicken breasts instead of thighs?
Yes — use bone-in or boneless breasts. Reduce cook time by 5–10 minutes and check doneness with a thermometer to avoid dryness.

2. Do I need to peel the potatoes?
Nope! Baby potatoes or Yukon golds have thin skins that roast beautifully. Just wash well and halve or quarter for even cooking.

3. Can I prep this ahead of time?
Yes. Sear the chicken and prep the veggies and sauce earlier in the day. Store covered in the fridge and roast when ready to eat.

4. What mushrooms work best?
Cremini or baby bella mushrooms are best for earthy flavor and meaty texture. White button mushrooms work too.

5. Can I make this in a Dutch oven?
Absolutely. It’s perfect for Dutch oven roasting and will help maintain moisture and even cooking.

6. What if I don’t have fresh herbs?
Dried rosemary and thyme are great substitutes. Use ⅓ the amount of fresh and add early so the flavors infuse.

7. How do I reheat leftovers?
Warm in a skillet over low heat or in the oven at 350°F for 15–20 minutes. Add a splash of broth or cream to loosen the sauce if needed.
