Roast Chicken and Fennel Ingredients
• Prepare for a comforting feast!
For the Chicken
- 8 bone-in, skin-on chicken thighs – The main protein, delivering rich flavor and moisture; substitute with boneless, skinless thighs for a quicker cook.
- 1 teaspoon neutral cooking oil – Used for searing chicken; any light oil works perfectly.
For the Vegetables
- 1 yellow onion (peeled and diced) – Adds natural sweetness and depth to the dish.
- 1 fennel bulb (cored and sliced, fronds reserved) – Provides a unique flavor and texture; can be replaced with leeks if needed.
- 1 pint cherry tomatoes (halved or left whole) – Adds juiciness and a burst of flavor; substitute with diced regular tomatoes if necessary.
- 5 cloves garlic (peeled, crushed, and roughly chopped) – Enhances aroma and flavor; pre-minced garlic can be a quick alternative.
- 2 tablespoons lemon juice – Brightens the overall flavors; can be replaced with white wine vinegar for a different punch.
- 1 teaspoon red pepper flakes – Adds a touch of heat; adjust according to spice preference or omit.
For the Sauce
- ½ cup water, wine, or stock (plus more as needed) – Helps deglaze the skillet and create a rich sauce; choose low-sodium broth for a healthier option.
- 2 tablespoons butter – Adds richness and gloss to the sauce; olive oil works as a dairy-free substitute.
For the Mashed Potatoes
- 1 pound Yukon gold potatoes (peeled and quartered) – Creamy base for delicious mashed potatoes; russet potatoes can also be used.
- 2 tablespoons butter (for mashed potatoes) – Enhances creaminess; consider olive oil for a vegan option.
- 2 teaspoons garlic powder – Adds garlic flavor; can be swapped with fresh garlic for a stronger taste.
- ½ cup heavy cream – Provides indulgent richness; substitute with milk or plant-based cream for lighter alternatives.

How to Make Roast Chicken and Fennel
-
Prepare Mashed Potatoes: Boil the quartered potatoes in salted water for 20-25 minutes until they are fork-tender. Drain the potatoes, return them to the pot, and mix in butter, garlic powder, heavy cream, salt, and pepper; mash until smooth and creamy.
-
Cook Chicken: Preheat your oven to 400°F. Heat oil in a skillet over medium-high heat, season your chicken thighs with salt and pepper, then sear skin-side down for about 5-7 minutes until golden brown. Flip the chicken and sear for another 1-2 minutes, then remove it from the skillet.
-
Sauté Aromatics: Using the same skillet, add diced onion and sliced fennel, cooking them for 5-7 minutes until they soften. Then, stir in halved cherry tomatoes, crushed garlic, lemon juice, and red pepper flakes. Season with salt and pepper, cooking it for an additional 2-3 minutes for a flavorful base.
-
Make Sauce: Pour in the water, wine, or stock, and scrape up any browned bits from the skillet for added flavor. Mix in 2 tablespoons of butter and allow it to melt, stirring to combine and adjust the seasoning as necessary.
-
Roast Chicken: Nestle the seared chicken thighs among the sautéed vegetables in the skillet, then transfer it to the preheated oven. Roast for about 20-25 minutes until the chicken hits an internal temperature of 165°F, ensuring juicy perfection.
-
Serve: Reheat the creamy mashed potatoes, spoon them into bowls, and generously top with the vegetable mixture, placing 1-2 chicken thighs on each serving. For a lovely finishing touch, garnish with reserved fennel fronds and extra red pepper flakes if you crave a bit more heat.
Optional: Drizzle with a touch of olive oil for added richness.

Roast Chicken and Fennel with Creamy Mashed Potatoes Recipe FAQs
What kind of fennel should I choose for this recipe?
Absolutely! Look for fennel bulbs that are firm, without any soft spots or browning. The fronds should be bright green and fresh-looking. Avoid any bulbs that have dark spots all over, as this indicates overripeness.
How should I store leftover Roast Chicken and Fennel?
Leftovers can be stored in an airtight container in the fridge for up to 3 days. It’s essential to let the dish cool before sealing it to prevent moisture buildup, which can affect the quality. When you’re ready to enjoy, simply reheat gently in the oven to maintain that juicy chicken texture.
Can I freeze the Roast Chicken and Fennel?
Yes, you can absolutely freeze this dish! Place the cooked roast chicken and fennel in freezer-safe containers or heavy-duty freezer bags. Make sure to squeeze out excess air to avoid freezer burn. It will keep well for up to 3 months. To reheat, thaw overnight in the fridge and warm in the oven at 350°F until heated through.
What should I do if my chicken skin isn’t crispy?
No worries! If your chicken skin isn’t coming out as crispy as you’d like, it might be due to excess moisture on the skin before you sear. Pat the chicken dry with paper towels to get rid of moisture. Furthermore, ensure you’re searing on medium-high heat and not overcrowding the pan, as this can trap steam.
Are there any dietary considerations for this recipe?
This dish contains chicken and dairy, which may not be suitable for everyone. If you’re prepping for someone with a dairy allergy or lactose intolerance, consider substituting the heavy cream with plant-based cream or milk and use olive oil in place of butter. As for pets, it’s best not to share cooked chicken with them, especially if seasoned.
Can I modify the ingredients based on what I have at home?
Very much so! If you can’t find fennel, leeks are a lovely substitute that can bring a similarly mild, sweet flavor. For a unique twist, add seasonal vegetables like asparagus or Brussels sprouts instead of fennel. Don’t hesitate to play with your flavors to create a version of Roast Chicken and Fennel that suits your taste!
