Single Sheet Pan Dinner: Mediterranean Chicken Thighs with Fingerlings, Tomatoes, Olives & Arugula 🍋🫒

If you’re building a simple weekly dinner rotation, this is one to keep on repeat.

This Mediterranean-inspired sheet pan dinner is colorful, nourishing, deeply flavorful, and surprisingly easy. It’s made with boneless chicken thighs, fingerling potatoes, grape tomatoes, red onion, garlic, Kalamata olives, and finished with fresh arugula and lemon juice.

It feels cozy and comforting, but also fresh and vibrant.

And the best part is that it all cooks on one pan. ✨

Simple, but layered in flavor

There’s no complicated marinade. No special sauce. Just good ingredients roasted together at high heat so they caramelize, soften, blister, and mingle into their own natural pan sauce.

The tomatoes burst.
The onions caramelize.
The garlic turns mellow and sweet.
The olives add that briny Mediterranean depth.

And then, right at the end, you scatter fresh arugula over the warm pan and squeeze lemon juice on top.

That’s the magic.

Do You Need to Marinate First

Short answer: No.

When you’re grilling skewers, marinating is helpful because high heat and airflow evaporate moisture quickly. But for sheet-pan roasting, marinating vegetables can actually cause them to steam instead of caramelize. We don’t want that for this meal.

Dry roast → then finish with acid.

That’s the winning formula here.

A Note on Oil (Because It Matters)

For high-heat roasting (425°F), I like using avocado oil because it handles heat well and has a neutral flavor.

After roasting, I often drizzle a little extra virgin olive oil over the finished dish for added flavor and richness.

This gives you:

• Heat stability while cooking
• Fresh flavor and antioxidants at the end

Simple and balanced.

Kalamata Olives: Straight from the Jar?

Yes.

Just drain them and scatter them over the pan. No need to dry them completely. Brined olives roast beautifully and add incredible savory depth to the dish.

Leftovers Are Incredible

This might be my favorite part.

The next day:

• The flavors deepen.
• The potatoes soak up even more lemon and olive notes.
• The arugula softens and wilts into the dish.

It makes an amazing next-day lunch bowl… especially with a little extra squeeze of lemon and a drizzle of olive oil.
