Ingredients for Piri Piri Chicken & Smashed Sweet Potato Traybake
- 2 large sweet potatoes (about 2 lbs), peeled and cut into 2 inch chunks
- 2 tablespoons olive oil, divided
- 6-8 bone in, skin on chicken thighs
- 2 red onions, cut into wedges
- 1 (1 oz) packet piri piri seasoning (or use a mild version)
- 1 bunch broccoli (or 10 oz broccolini)
- Salt and black pepper
Instructions for Making Piri Piri Chicken & Smashed Sweet Potato Traybake
1Prep and Season: Preheat your oven to 400°F (200°C).
On a very large, rimmed baking sheet, toss the sweet potato chunks with 1 tablespoon of the olive oil and a generous pinch of salt and pepper. Push the potatoes to one side of the pan.
In a large bowl, combine the chicken thighs and red onion wedges with the remaining 1 tablespoon of olive oil and the piri piri seasoning. Toss until everything is evenly coated. Arrange this mixture on the empty side of the baking sheet.
2Roast to Golden Perfection: Roast for 40 minutes, stirring everything and flipping the chicken thighs halfway through the cooking time. This ensures everything gets beautifully browned and cooks evenly.
3Add the Broccoli and Finish: After 40 minutes, remove the pan from the oven. Add the broccoli to the pan, drizzle it lightly with a bit more oil, and season with salt and pepper.
Return the pan to the oven and roast for another 10-15 minutes, until the broccoli is tender crisp and the chicken skin is deep golden brown and crispy.
4The Magic “Smash” Step: Carefully transfer the chicken, onions, and broccoli to a serving platter.
Using a fork or a potato masher, roughly smash the roasted sweet potatoes right there in the baking sheet. Make sure to scrape up and incorporate all the delicious, spicy chicken juices and browned bits from the bottom of the pan; this is where the magic is!
5Serve Family Style: Spread the smashed sweet potatoes evenly over the bottom of the pan. Artfully arrange the crispy chicken, roasted onions, and broccoli on top. Bring the entire pan to the table for a beautiful, family style presentation that’s sure to impress.

Notes
- Pan Size is Key: Use the largest baking sheet you have to avoid overcrowding, which steams the food instead of roasting it.
- Spice Level: Piri piri seasoning can vary in heat. Look for a "mild" version if you're sensitive to spice.
- Crispy Chicken Skin: For the crispiest skin, pat the chicken thighs completely dry with a paper towel before seasoning.
