Press SAUTE function +10 minutes on Instant Pot. Melt butter. Add meat and brown for 3 - 4 minutes. It's best to brown meat in a few small batches to get the best color. Stir in vegetables and batches of meat that were previously browned. Stir in tomato paste.

Add broth, salt, pepper, and xanthan gum to the pot. Stir well to combine ingredients. Turn Instant Pot OFF, then press STEW function +40 minutes.

When the timer goes off, manually release steam. Sprinkle and stir in very small amounts of xanthan gum to desired consistency. Garnish with fresh parsley to serve if desired.

If you don’t have an Instant Pot - have no fear, you can do this in a slow cooker as well. Simply add all the ingredients into the slow cooker, stirring until well-combined, and then cook on low for 8 hours.
