Add the avocado oil to a large thick-bottomed pot (I use my Dutch oven) and heat to medium-high.
Add the onion and saute, stirring frequently, until it begins to turn golden-brown, about 8 minutes.
Move the onions off to the side and add the stew meat. Allow it to brown on one side for 2 minutes then flip to brown on another side for 1 minutes.
Add the remaining ingredients for the stew to the pot and bring it to a full boil. Cover and reduce the heat to a simmer.
Cook at a gentle simmer, stirring occasionally, for 1 hour. Taste the chili for flavor and add more sea salt to taste.
If you’d like a thicker chili, add 2 tablespoons of gluten-free flour (or regular all-purpose flour), stir well, bring to a boil, and cook until the chili reaches your preferred consistency.
Serve steak chili with your choice of toppings and enjoy.
