👩🍳 Expert Tips
- Sauté Vegetables and Spices: Begin by using the sauté function to cook onions, bell peppers, and spices like cumin and chili powder. This step helps release their flavors, creating a more aromatic and rich base for your soup.
- Use Chicken Thighs: Opt for chicken thighs instead of breasts. Thighs are more flavorful and tend to stay juicier under pressure, making them perfect for soup.
- Deglaze with Broth: After sautéing, add a splash of chicken broth to deglaze the pot, scraping up any bits stuck to the bottom. This incorporates all the caramelized flavors into the soup and prevents the burn message.
- Quick Release After Cooking: Once the cooking cycle is complete, use the quick release function to prevent the chicken and vegetables from overcooking. This helps maintain the texture and integrity of the ingredients.
