Step-by-Step Instructions

1. 1. **Prep & Sauté:** Press the **Sauté** button on your Instant Pot (set to Normal/Medium). Add cooking oil and sear your meat/aromatics for 4-5 minutes until browned.
2. 2. **Deglaze (Crucial to Prevent ‘Burn’ Error):** Pour in 1/2 cup of broth or cooking liquid. Use a wooden spoon to scrape up all browned bits (fond) stuck to the bottom of the inner pot.
3. 3. **Layer Ingredients:** Add remaining ingredients and at least 1 cup of thin liquid. *(Note: Reserve dairy and thickeners for after cooking)*
4. 4. **Pressure Cook:** Secure the lid and turn the steam release valve to **Sealing**. Select **Pressure Cook / Manual (High)** and set the timer for **29 minutes**.
5. 5. **Pressure Release:** When the timer beeps, perform a **Quick Pressure Release (QR)**.
6. 6. **Finish & Thicken:** Unlock the lid. Press **Sauté** again. Stir in reserved cream/cheese and cornstarch slurry. Simmer for 2-3 minutes until rich and thickened to your desired texture.
