Prep the chicken. Pat the chicken dry and cut into bite-size pieces.
Season lightly with salt and pepper. This helps the meat stay flavorful and tender.
Sauté aromatics. Set the Instant Pot to Sauté (Normal). Add oil or ghee.
Cook the chopped onion for 3–4 minutes until softened. Stir in garlic and ginger for 30–60 seconds, just until fragrant.
Toast the spices. Add curry powder, cumin, coriander, and turmeric. Stir for 30 seconds to bloom the spices.
If the pot looks dry, add a splash of oil to keep spices from sticking.
Deglaze. Pour in the broth or water and scrape up any browned bits from the bottom. This prevents the burn warning and builds flavor.
Add tomatoes and chicken. Stir in the diced tomatoes. Add the chicken and any firm veggies (like potatoes or bell peppers). Mix well so everything is coated.
