Crispy Peanut Roast Chicken with Lime Pea Sauce
A one-pan roast that combines tender chicken thighs with crunchy peanut-crusted potatoes and a vibrant, herbaceous pea sauce. The dish balances rich, salty peanuts against bright lime and fresh coriander and basil, creating layers of flavor and texture in every bite. Roasting the potatoes at high heat creates golden, crispy edges while the chicken skin crisps alongside. The blended pea sauce—half smooth, half chunky—adds freshness and mild pepper sweetness. This is weeknight cooking that feels special, suited for anyone wanting restaurant-quality results without fuss. Serve it warm from the pan for casual family dinner or a relaxed gathering. What sets this apart is the two-stage oven technique that ensures both potatoes and chicken cook perfectly, plus the uncooked herb finish that brightens everything on the plate.

Instructions
- 1
Put potatoes in a large pan, cover with cold water, bring to boil, then simmer for 15 minutes. Drain and cool in colander.

Heat oven to 425°F/400°F fan/gas 7. Pour 2 tbsp oil into a large roasting tin and place in oven to heat.

Once potatoes are cool enough to handle, rough up their edges with a fork or potato masher, then slide into the hot roasting tin. Toss in oil, season with salt and pepper, and roast for 10 minutes.

Turn oven down to 400°F/350°F fan/gas 6. Sprinkle peanuts over potatoes, add chicken to tin, and roast for 30 minutes or until chicken is cooked.

While chicken roasts, boil peas for 2 minutes, drain and rinse under cold water. Blend half the peas in a food processor with remaining oil, green pepper, half the green onions, lime zest and juice, and most of the herbs until combined. Taste and season, then stir in the rest of the peas.

To serve, sprinkle remaining green onions and herbs over the tray and serve pea sauce on the side.
Tips
Rough up potato edges after cooling: creates extra surface area for crisping. Fork-scarred skin crisps harder than smooth surfaces, giving you maximum textural contrast between fluffy interior and crackling exterior.
Blend only half the peas: leaves you with chunky-smooth sauce that coats without becoming puree. This preserves individual pea flavor and creates better mouthfeel than fully processed.
Add herbs after roasting: fresh coriander and basil wilt when hot. Sprinkling them over the finished dish keeps their aroma and bright flavor intact rather than cooking them into muted background notes.
Good to Know
Cover and refrigerate leftover roasted vegetables and chicken for up to 3 days. Pea sauce keeps 2 days. Reheat gently at 160°C until warm; do not microwave chicken skin as it loses crispness.
Potatoes can be par-boiled and cooled 4 hours ahead. Pea sauce can be made 1 day ahead and stored covered. Assemble and roast as directed on the day.
Serve warm from the roasting tin with lime wedges on the side. Pairs well with a crisp white wine, cold beer, or iced lemon water.
Common Mistakes
Do not skip the colander cooling step to avoid soggy potatoes; moisture prevents crisping.
Do not overcrowd the roasting tin to avoid steaming instead of roasting; use a large tin.
Do not blend all the peas to avoid a thin, pureed sauce; leave half chunky for texture and body.

FAQ
Can I use a different cut of chicken?
Thighs are ideal for roasting because the higher fat content keeps them moist even at high heat. Breasts work but dry out easily; reduce the final roast time to 20-25 minutes or cover loosely with foil. Drumsticks need 35-40 minutes.
What if I don't have fresh herbs?
Fresh coriander and basil are essential to the final dish's brightness. If unavailable, substitute parsley or mint, but the flavor profile shifts noticeably. Dried herbs do not work well here; the dish relies on the aroma of fresh herbs sprinkled at the end.
Can I freeze leftovers?
Yes. Cool completely, then freeze chicken, potatoes, and pea sauce in separate containers for up to 3 months. Thaw overnight in the fridge. Reheat chicken and potatoes at 160°C until warm; gently warm pea sauce on the stovetop. Do not microwave to preserve crispy potato skin.
