Turn the oven to 200 °C, convection if you have it, otherwise regular bake.
Cut the sweet potatoes
Wash the sweet potatoes and cut them into 2 cm cubes, skin on if you like. Finely mince the 2 garlic cloves and strip the leaves off the rosemary sprig.
Season the sweet potatoes
In the bowl, toss the sweet potatoes with half the olive oil and a little salt and pepper. Spread them on the baking sheet, leaving room for the chicken.
Prep the thighs
Pat the thighs dry with paper towels. Rub them with the rest of the oil, the minced garlic, rosemary, salt and pepper, then lay them skin side up on the sheet, between the sweet potatoes.
Tip · Drying the skin before seasoning is what makes it crispy. Damp skin steams instead of browning.
Roast the chicken and sweet potatoes
Slide the sheet onto the middle rack at 200 °C. Let it cook without touching it.
Flip the sweet potatoes
Take out the sheet, stir the sweet potatoes so they brown on all sides and set the thighs back skin side up. Put it back in the oven.
Tip · Don't crowd the sweet potatoes on the sheet: packed tight, they go soft instead of roasting. Spread them in a single layer.
Check it's cooked
Poke the thigh at its thickest point near the bone: the juices should run clear, no pink, and the inside should reach 75 °C. If not, give it 5 more min.
Rest and serve
Take out the sheet and let the thighs rest under foil or just uncovered. Serve them with the roasted sweet potatoes.
And there you go, it's readyCheck off every step to celebrate.
