Ingredients: 1 whole chicken (2.5–5 lb (1.1–2.3 kg), skin on, giblets removed, patted very dry); 1 cup plain whole-milk yogurt; ¼ cup fresh lemon juice; 3 tbsp tandoori masala; 2 tbsp Kashmiri red chili powder; 1 tbsp ginger paste; 1 tbsp garlic paste; 1 tbsp mustard oil; 2 tsp garam masala; 1½ tsp ground cumin; 1 tsp ground coriander; 1 tsp turmeric powder; 2 tsp salt; 1 cup water; 1 metal trivet; 2 tbsp melted butter or ghee; fresh coriander; 1 large red onion; 1 tbsp lemon juice; ¼ tsp chaat masala; pinch salt; fresh coriander

Imagine carving into a whole bird with flame-red, char-kissed skin and finding the meat underneath impossibly juicy — that is this instant pot whole tandoori chicken. A whole chicken spends the night in a tangy yogurt marinade loaded with tandoori masala, garlic, ginger and Kashmiri chili, then pressure cooks in the Instant Pot until fall-off-the-bone tender. A short blast under the broiler at the end crisps and chars the skin just like a tandoor would. And here is the part most recipes skip: you’ll get exact pressure-cooking times by bird weight, so your chicken is perfect whether it’s 2.5 or 5 pounds.

Instant Pot Whole Tandoori Chicken Ingredients

For the Whole Chicken

1 whole chicken, 2.5–5 lb (1.1–2.3 kg), skin on, giblets removed, patted very dry

For the Tandoori Yogurt Marinade

1 cup plain whole-milk yogurt (not Greek — regular yogurt coats a whole bird better)
¼ cup fresh lemon juice (about 2 lemons), plus lemon wedges to serve
3 tablespoons tandoori masala
2 tablespoons Kashmiri red chili powder (for that classic red color without harsh heat)
1 tablespoon ginger paste
1 tablespoon garlic paste
1 tablespoon mustard oil (or any neutral oil)
2 teaspoons garam masala
1½ teaspoons ground cumin
1 teaspoon ground coriander
1 teaspoon turmeric powder
2 teaspoons salt, plus more to taste

For the Instant Pot and Finishing

1 cup water
1 metal trivet (the one that came with your Instant Pot)
2 tablespoons melted butter or ghee, for brushing
Fresh coriander leaves, chopped (for garnish)

For the Onion Salad (to serve)

1 large red onion, thinly sliced into rings
1 tablespoon lemon juice
¼ teaspoon chaat masala (optional but lovely)
A pinch of salt
Fresh coriander, chopped

How to Make Instant Pot Whole Tandoori Chicken

Step 1: Score and Marinate the Bird

Using a sharp knife, make 4–5 deep slashes on each breast and 2–3 on each thigh and drumstick, cutting down to the bone. This lets the marinade reach the meat. Whisk all the marinade ingredients in a large bowl, then rub the mixture all over the chicken — inside the cavity, under the skin where you can reach, and deep into every slash. Cover and refrigerate at least 4 hours, ideally overnight (up to 24 hours) for the deepest flavor.

Step 2: Set Up the Instant Pot

Pour 1 cup of water into the inner pot and place the trivet inside. Lift the marinated chicken out of the bowl, letting excess marinade drip off, and set it breast-side up on the trivet. (Leaving a little marinade on is fine — it becomes part of the cooking liquid.)

Step 3: Pressure Cook by Weight

Lock the lid, set the valve to Sealing, and cook on High Pressure using the timing below, followed by a 10-minute natural release, then quick-release any remaining pressure:

Whole chicken weight	High Pressure time
2.5 lb (1.1 kg)	15 minutes
3 lb (1.4 kg)	18 minutes
3.5 lb (1.6 kg)	21 minutes
4 lb (1.8 kg)	24 minutes
4.5 lb (2 kg)	27 minutes
5 lb (2.3 kg)	30 minutes

This works out to about 6 minutes per pound — the rule to remember if your bird falls between sizes.

Step 4: Broiler Finish for Charred Skin

Heat your oven’s grill/broiler to its highest setting. Carefully lift the chicken (breast-side up) onto a foil-lined baking tray. Brush generously with melted butter or ghee, then grill 8–12 minutes until the skin blisters and chars in spots, turning the tray once halfway. Watch closely — Kashmiri chili can go from charred to burnt quickly.

Step 5: Rest, Then Carve

Rest the chicken for 10 minutes before carving — this keeps the juices in the meat. Check that the thickest part of the thigh reads 74°C / 165°F on an instant-read thermometer (the safe whole chicken internal temp). Carve and serve over the onion salad with lemon wedges.

Tips for the Best Instant Pot Tandoori Chicken

Dry the skin before marinating. Moisture is the enemy of charring — patting the bird dry first helps the marinade cling and the broiler char properly.
Score deeply. Shallow cuts only flavor the skin; cutting to the bone is what makes tandoori spices reach the meat of a whole bird.
Don’t skip the natural release. A full quick release on a whole chicken can make the breast meat seize and turn rubbery — 10 minutes of natural release keeps it tender.
Trivet, not the pot floor. The chicken must sit above the water, not in it, or the bottom will steam instead of roast.
Kashmiri chili is the color. Regular chili powder gives heat but a duller color; Kashmiri chili gives the glowing tandoor red with gentle warmth.
Strain the drippings. The liquid left in the pot is intensely flavored — strain and reduce it for a drizzle, or spoon it over rice.

What to Serve with Whole Tandoori Chicken

A whole tandoori roast chicken begs for classic accompaniments: warm naan or tandoori roti, fragrant basmati or jeera rice to catch the juices, and a cooling cucumber mint raita to balance the spices. The red onion salad in this recipe (with lemon and chaat masala) is non-negotiable — it’s the traditional tandoori-sidekick. For a dinner party, add a simple dal and a kachumber salad and you’re done.

Storage and Reheating

Refrigerator: Carve leftovers off the bone and store in an airtight container for up to 4 days. The meat stays moist thanks to the yogurt marinade.
Freezer: Freeze shredded or sliced leftover tandoori chicken for up to 3 months. Thaw overnight in the fridge.
Reheating: Warm gently in a covered pan over low heat with a splash of water, or in a 160°C (325°F) oven covered with foil. To re-crisp the skin, finish under the broiler for 2–3 minutes.
Leftover ideas: Leftover tandoori chicken is a gift — pile it into wraps with the onion salad, toss through fried rice, fold into a creamy pasta, or layer into a tandoori chicken sandwich with mint chutney.

Instant Pot Whole Tandoori Chicken FAQs

How long do you cook a whole chicken in the Instant Pot?
About 6 minutes per pound on High Pressure, plus a 10-minute natural release. A 4 lb chicken needs 24 minutes; use the weight chart above for other sizes and always confirm 74°C / 165°F in the thickest part of the thigh.

How do I get crispy, charred skin on Instant Pot chicken?
The pressure cooker can’t brown, so the broiler finish does the work: brush the cooked bird with butter or ghee and grill on high for 8–12 minutes until blistered and charred in spots.

Can I marinate the chicken overnight?
Yes — overnight (up to 24 hours) is ideal. The yogurt tenderizes the meat and the spices penetrate deeply through the slashes. Don’t go past 24 hours or the yogurt can make the texture mushy.

What is the safe internal temperature for whole chicken?
74°C / 165°F in the thickest part of the thigh, away from the bone. The pressure-cooking times above get you there; always verify with a thermometer since Instant Pot models and bird shapes vary.

Can I make this without an Instant Pot?
You can roast instead: marinate as directed, then roast at 200°C (400°F) for about 20 minutes per pound until the thigh reads 74°C / 165°F, basting once. You lose the set-and-forget convenience but gain a great result either way.
