This baked lemon pepper chicken came out of an Airbnb kitchen ritual: whenever I arrive somewhere new, one of the first things I do is inspect the kitchen and pantry. I take a quick inventory of what’s already there, so I can plan meals around it and keep grocery shopping to a minimum. On this recent stay, the pantry had a jar of lemon pepper seasoning, and that became the starting point. My husband liked it so much he asked me to pick up the same seasoning once we got home so I’d make it again, and it’s stayed in our rotation ever since.
It comes together in one baking dish: chicken thighs go in with fennel, bell peppers, olives, and cherry tomatoes, and the oven does the rest. I like to serve it with a whole grain and a green salad on the side.
Why You’ll Love This Recipe
- One dish, minimal cleanup. Everything roasts together, so there’s no juggling pans.
- The lemon pepper seasoning does most of the flavor work, so this comes together fast even on a night when you don’t feel like cooking from scratch.
- It’s easy to adjust. Swap the olives, use whatever colors of bell pepper you have, or leave off the fennel if you’re not a fan.
Ingredients
Here’s what goes into this lemon pepper chicken (full amounts are in the recipe card below):
- Chicken thighs, bone-in and skin-on. Unlike leaner breast meat, they stay juicy through the long bake and the skin crisps up nicely.
- Fennel bulb, quartered, cored, and thinly sliced. It softens as it roasts, turning sweet while keeping its light anise flavor.
- Bell peppers, one yellow and one orange for color, though any combination works.
- Onion, thinly sliced, for the base.
- Garlic, sliced thin so it roasts rather than burns.
- Olives, kalamata or green, whatever you have on hand.
- Cherry or grape tomatoes, added partway through so they stay plump instead of collapsing.
- Lemon pepper seasoning blend, mixed with a little oregano, forms the rub for the chicken.
- Olive oil and fresh lemon juice tie everything together and keep the vegetables from drying out.
A quick nutrition note: bone-in chicken thighs bring protein and iron, the olive oil and olives add monounsaturated fat, and between the fennel, peppers, and tomatoes you’re getting a solid mix of fiber and vitamin C in the same dish.

I like to serve this with a whole grain like red rice or farro and a simple green salad on the side, which rounds it out into a full Mediterranean Diet dinner. Crusty bread works well too, for soaking up the juices left in the dish.
FAQs
No. Roasting mellows and sweetens fennel while keeping its light anise flavor, so it’s a fairly gentle way to try it if you’re on the fence. If you’d still rather skip it, add a bit more onion or another sliced bell pepper in its place.
A store-bought lemon pepper blend typically includes dried lemon peel, salt, pepper, and often garlic or onion powder, so it holds its flavor through a long bake and gives you a consistent, concentrated citrus-pepper hit in every bite. Fresh lemon zest and cracked pepper taste brighter and more fragrant right when you use them, but that brightness fades with oven heat, and you’d need to add salt and other seasoning separately to match the same depth. They’re not interchangeable one for one. If you want to use fresh zest and pepper instead, add a pinch of salt and maybe a little garlic powder to compensate.
Bone-in, skin-on thighs are what makes this recipe work. They hold up through the full 45-minute bake without drying out, and they release a lot of flavorful juice as they cook, which blends with the vegetables underneath. Boneless chicken breasts don’t have that same fat and connective tissue, so they’d likely dry out and you’d lose that pan juice entirely. If you’re looking to use chicken breasts, it’s worth finding a recipe written specifically for them rather than substituting here.
Kalamata olives give the most traditional Mediterranean flavor, but green olives work well too if that’s what you have.
Advance Prep & Storage
You can quarter, core, and slice the fennel, and slice the peppers and onion, up to a day ahead and store them in the fridge in an airtight container. The chicken can also be seasoned a day ahead, which actually helps: the salt in the lemon pepper blend acts like a light dry brine overnight, resulting in more flavorful, juicier chicken once baked.
Leftovers keep in the fridge for 3 to 4 days in an airtight container. Reheat in a 350°F oven until warmed through, or in the microwave if you’re short on time. This dish also freezes well; thaw overnight in the fridge before reheating.
