• Turn on your Instant Pot, add the avocado oil, and press the Saute function. Add the chopped onion and saute, stirring occasionally, until onion is transluscent, about 5 minutes. 
• Add the beef stew meat and brown 1 to 2 minutes (do not cook through).
• Add the remaining ingredients for the stew and stir well. Secure the lid on your Instant Pot and press the Stew/Meat button. Adjust the time setting to 15 minutes. Set to Sealing.
• Once the stew has finished cooking, allow it to naturally vent until it completes its cycle (about 20 - 30 minutes). 
• For thicker stew, press either Sauté or Boil on your pressure cooker and bring the stew to a full boil. Stir occasionally and allow the stew to boil until it has reached your desired thickness. You can also add 1 to 2 tablespoons of gluten-free all-purpose flour or tapioca flour to help thicken the stew.

Slow Cooker Option:

• Add oil to a skillet and heat over medium. Add the onion and saute until translucent, about 5 minutes. Add the stew meat and brown for 2 to 3 minutes. 
• Transfer onion and beef to your slow cooker along with the rest of the ingredients for the stew. Stir well and secure the lid on your slow cooker. Cook on low 6 to 8 hours, until beef is nice and tender.
