Ingredients

• 4 bone-in, skin-on chicken thighs (about 2 lb / 900 g total)
• 1 lb (450 g) baby potatoes, halved (or quartered if large)
• 3 medium carrots (about 250 g), cut into 2-inch batons
• 1 medium zucchini (about 250 g), cut into 3/4-inch half-moons
• 3 tablespoons garlic-infused olive oil, divided
• 1 1/4 teaspoons fine salt, divided
• Freshly ground black pepper
• 1 teaspoon sweet paprika
• 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
• 1 teaspoon fresh rosemary, chopped (or 1/2 teaspoon dried)
• 1 lemon, half sliced into thin rounds, half reserved for juice
• 2 tablespoons sliced scallion greens, to finish

Instructions

Prep

1. Heat the oven to 425°F (220°C). Line a large rimmed sheet pan (half-sheet, 18 by 13 inches) with parchment. If your pan is smaller, use two pans so nothing steams.
2. Pat the chicken thighs dry with paper towels. Dry skin crisps; wet skin steams.
3. In a small bowl, mix 1 tablespoon of the garlic-infused oil with the paprika, 1/2 teaspoon of the salt, several grinds of pepper, and half the thyme and rosemary. Rub the mixture all over the thighs, including under the skin.

Roast the vegetables first

1. Toss the potatoes and carrots on the sheet pan with 1 tablespoon of the garlic-infused oil, 1/2 teaspoon salt, and pepper. Spread in a single layer.
2. Roast for 15 minutes. The potatoes and carrots need a head start; zucchini and chicken cook faster.

Add chicken and zucchini

1. Toss the zucchini with the remaining 1 tablespoon oil, 1/4 teaspoon salt, pepper, and the remaining herbs.
2. Pull the sheet pan out. Push the potatoes and carrots to one side. Add the zucchini to the empty space and the chicken thighs skin-side up on top. Scatter the lemon slices around the pan.
3. Return to the oven and roast for 20 to 25 minutes, until the chicken skin is deep golden and an instant-read thermometer in the thickest part of a thigh reads at least 165°F (74°C). Thighs are most tender closer to 175°F (80°C), and the bone makes them forgiving past that point.

Finish

1. Squeeze the juice from the reserved lemon half over the pan.
2. Scatter the scallion greens over the top and add a final grind of black pepper. Rest 5 minutes before serving so the juices settle.

Tips & Substitutions

• Use other low-FODMAP vegetables. Red bell pepper, green beans, and eggplant all work here. Look up each one in the FODMAP Foods app to see how its rating changes with portion size, and keep portions in range. Add tender veg like bell pepper and green beans in the second stage with the zucchini; they cook in 20 minutes or less.
• Use boneless thighs if you prefer. Reduce the second-stage roast to 15 to 18 minutes and check for 165°F (74°C) internal temperature. The skin won't crisp as dramatically as bone-in, skin-on.
• No fresh herbs on hand. Dried thyme, rosemary, and oregano all hold up to roasting. Use half the quantity.
• Don't use regular onion or garlic. Regular onion and garlic contain fructans. Garlic-infused oil and scallion greens cover the aromatic base without the fructans.
• Skip the mushroom temptation. Common button and portobello mushrooms become high-FODMAP (mannitol) quickly, so they're a risky choice for a shared roasting pan. If you want mushrooms, use a variety Monash rates low-FODMAP, such as oyster mushrooms, and keep the portion small.
• For crispier skin, broil the pan for the last 2 to 3 minutes. Watch closely; the lemon slices darken fast.

Why This Works

The aromatic swap keeps it flavorful. Traditional sheet pan chicken starts with onion and garlic for its savory base. Garlic-infused oil delivers the same garlic flavor without the fructans, which don't dissolve in oil and stay behind in the solids when strained. Scallion greens add a mild allium note; only the green tops are low-FODMAP (the white bulbs are high). See the full method in the garlic-infused olive oil recipe.

The portioned vegetables stay low FODMAP. Potatoes and carrots are low FODMAP at generous serves, and zucchini is low at 65 g, so this recipe keeps it to about 60 g per serving.

Staggered timing prevents mushy zucchini and raw potato. Dense root vegetables need 30 to 35 minutes to roast through; zucchini turns to slurry in that time. Giving the potatoes and carrots a 15-minute head start, then adding the zucchini with the chicken, lands everything at the same finish line.

Bone-in, skin-on thighs are forgiving. The bone slows heat transfer and the skin renders fat that bastes the meat, so even a few minutes past target won't dry them out. At 425°F the skin crisps while the potatoes brown underneath.

Storage

Refrigerate in a sealed container for up to 3 days at 40°F (4°C) or below. Reheat in a 400°F oven for 8 to 10 minutes, until the chicken reaches 165°F (74°C); the microwave works in a pinch but turns the skin rubbery. The chicken and potatoes freeze well for up to 2 months; the zucchini does not (it weeps on thaw), so pick it out before freezing if you're batch-cooking.
