Remove the meat from the cooked turkey or chicken. Shred it into bite-size strips and keep it in the fridge until serving.
Peel and dice the onion into 1-inch chunks. Scrub the ginger clean, pat dry, and cut into 1-inch pieces (no need to peel). Peel the garlic cloves and leave them whole.
Warm up the broiler for 5 minutes. Place the onion, ginger, and garlic on a sheet pan. Broil on the middle rack for 5–7 minutes, then rotate and broil the other side for another 5–7 minutes. They should smell fragrant and lightly charred.
Press Sauté → Normal on your Instant Pot. Once it says “Hot,” add the star anise, cinnamon stick, and fennel seeds. Dry roast for about 5 minutes, tossing often, until fragrant. Press Cancel.
Add the roasted onion, ginger, and garlic to the pot. Add the turkey or chicken carcass, shiitake, and pour in chicken stock until it reaches at least the 3-liter mark. You can top it off with water if needed.
Press Slow Cook → Low for 7–8 hours, or High for 4–5 hours. Don’t open the lid during cooking.
Cook the pho noodles in a separate pot according to package instructions. Do this when you’re close to serving.
When the broth is done, strain out the carcass and aromatics. Keep the shiitake mushrooms and the clean broth.
Return the broth and mushrooms to the pot. Press Sauté and taste the broth before seasoning. Add salt, fish sauce, sugar, and lime juice —start small and adjust to your taste.
Add the bok choy and simmer for 1 minute. Press Cancel.
To serve, add the cooked noodles to each bowl first. Then top with the shredded turkey or chicken and a handful of bean sprouts. Ladle the hot broth over everything and serve right away. If you like, add sliced jalapeño, a drizzle of hoisin, or a bit of sriracha with extra lime wedges on the side.

Notes
The shredded turkey or chicken and bean sprouts are added directly to each bowl—not simmered in the turkey bone broth. This keeps the meat tender, the sprouts crisp, and the broth clear and clean.
Storage & Reheat: Store the broth on its own and keep the noodles and toppings separate. Reheat the broth and add the noodles right before serving.
Spice bags: If you have spice bags, add the roasted onion, ginger, garlic, and dry-toasted spices in separate bags so they’re easy to remove later. Don’t pack them too tightly so the aromatics have room to release their flavor.
Best turkey to use: For a clean, pho-style turkey bone broth, use leftover turkey or chicken roasted with lighter, savory seasoning (herbs, citrus, soy-based marinades). These give you a clearer, more balanced broth.
Avoid butter-heavy roasts: Turkeys coated with a lot of butter (on and under the skin, plus buttery drippings) aren’t ideal for pho. They tend to make the broth heavy and greasy instead of light and clear.
