How to Make Lemon Thyme Chicken Thighs with Roasted Fennel & Olives
Step 1: Preheat the Oven
Before you start prepping anything else, set your oven to 425°F (220°C). A hot oven is key to crisping up the chicken skin and turning those veggies golden and caramelized around the edges. It’s a small detail that makes a big difference!
Step 2: Season the Chicken
Pat the chicken thighs really dry—this helps the skin get beautifully crispy. In a bowl, mix the olive oil, lemon zest, lemon juice, smashed garlic, fresh thyme, salt, and pepper. Rub this irresistible blend all over the chicken, making sure to get some of the flavor under the skin, too. The lemon and thyme infuse the meat, making Lemon Thyme Chicken Thighs with Roasted Fennel & Olives sing with flavor.
Step 3: Prepare the Fennel, Olives, and Onion
Slice up your fennel bulbs (don’t forget to keep some fronds for garnish!), toss them with the olives and red onion right in your roasting pan. Drizzle with olive oil, sprinkle with dried oregano, salt, and black pepper, then toss everything well so each piece is coated and ready to roast.
Step 4: Assemble and Nestle the Chicken
Arrange the seasoned chicken thighs skin-side up right on top of the vegetable mixture. Nestling them together lets all the flavors mingle as they cook—plus, the chicken juices baste the veggies, creating that signature Lemon Thyme Chicken Thighs with Roasted Fennel & Olives harmony.
Step 5: Roast to Golden Perfection
Slide your pan into the oven and let the magic happen for 35 to 40 minutes. You’re looking for deeply golden, crispy skin and an internal temperature of 165°F (74°C) in the thickest part of the thighs. The veggies beneath should be tender and caramelized, with bites of olive peeking through.
Step 6: Rest and Serve
Let the chicken rest for about 5 minutes to keep all those juices where they belong. Before serving, spoon some of the garlicky, lemony pan juices over the chicken and vegetables. It’s pure joy in every mouthful and the essence of Lemon Thyme Chicken Thighs with Roasted Fennel & Olives.
How to Serve Lemon Thyme Chicken Thighs with Roasted Fennel & Olives

Garnishes
Sprinkle reserved fennel fronds or extra fresh thyme leaves over the finished dish for a bright, herbal pop. A few lemon wedges on the side let everyone squeeze on extra zing as they please—so simple, but so impressive.
Side Dishes
Lemon Thyme Chicken Thighs with Roasted Fennel & Olives shines next to classics like buttery mashed potatoes, herby couscous, or warm crusty bread to mop up those luscious pan juices. You can even pair it with a crisp green salad for a lighter, Mediterranean-style meal.
Creative Ways to Present
Try serving everything straight from the roasting pan for a rustic, family-style presentation, or plate individual portions atop a swoosh of creamy hummus for a dinner-party vibe. It also tastes fabulous over fluffy polenta, letting those savory juices soak into every bite.
Make Ahead and Storage
Storing Leftovers
Cool any leftovers completely, then store them in an airtight container in the refrigerator for up to three days. The flavors deepen overnight, making Lemon Thyme Chicken Thighs with Roasted Fennel & Olives a dream for next-day lunches.
Freezing
Yes, you can freeze this dish! Place cooled chicken and veggies in a freezer-safe container and freeze for up to three months. Thaw overnight in the fridge for best texture, as the chicken skin may soften a bit but the flavors stay bold.
Reheating
To recapture that crispy skin, reheat the chicken uncovered in a hot oven (about 375°F) for 10–15 minutes, adding the vegetables for the last few minutes to warm through. Alternatively, pop everything in a covered skillet over medium-low heat until piping hot.
FAQs
Can I use boneless, skinless chicken thighs instead?
Absolutely! Boneless, skinless thighs will cook a bit faster, and while you’ll miss out on the crispy skin, the dish will still be packed with lemony, herbal goodness. Just keep an eye on cooking time to avoid overcooking.
What can I substitute for fennel if I don’t have it?
If fennel isn’t your thing or you can’t find it, try sliced leeks or celery paired with a touch of star anise for similar sweetness and a whisper of licorice flavor. Roasted carrots or parsnips also work nicely in Lemon Thyme Chicken Thighs with Roasted Fennel & Olives.
Can I use only one type of olive?
Definitely! Use whatever olives you love or have on hand. Kalamata, Castelvetrano, or classic green olives are all delicious in this recipe; mixing varieties simply adds a bit more complexity and color.
Can I prep this dish ahead for entertaining?
Yes! Marinate the chicken and prep the vegetables the night before. When company arrives, simply assemble in the pan and roast as directed. Your kitchen will smell incredible and you’ll have a stunning dish with minimal fuss.
Is Lemon Thyme Chicken Thighs with Roasted Fennel & Olives gluten-free?
Yes! As written, there’s no gluten involved, making it naturally gluten-free. If you’re serving with bread on the side, just opt for your favorite gluten-free variety to keep everyone happy.
