Set a dutch oven or heavy bottomed pot on medium high heat. Once hot, add avocado oil and beef sirloin. Add sea salt, pepper, oregano and thyme as it sears for about 4 minutes, or until deep marks appear on the beef. Then reduce the heat to medium and remove the beef.
Add olive oil, onion and carrot. Cook for 1 -2 minutes then sprinkle in the flour or starch and stir for 1 minute. Pour in the red wine and let it reduce by about half while you also deglaze (or scrape) the bottom of the pot with a wooden spatula to mix in all of the flavor trapped there. Add the beef back to the pot and stir into the reduced wine for 1 minute.
Increase the heat to medium high, then pour in the beef broth and add the potatoes and mushrooms. Add the bay leaf, then cover and cook for as little as 45 minutes; BUT, for best results and a thicker stew any time between 2 – 3 hours is best. In my opinion – 45 minutes for a weekly meal prep recipe, 2 – 3 hours for a Sunday family dinner!
Garnish with fresh thyme and enjoy!
