Heat oil in a large skillet over medium high heat.
Sea salt and pepper the beef and sear on each side for 2-3 minutes in your hot oil.
Transfer beef to the slow cooker.
Add the red wine to the same medium-high temperature skillet used for the beef, and allow it to simmer and reduce.
Whisk the flour separately first into the broth, then add that mixture into the skillet with the wine. Remove from heat, then whisk in the aminos, and tomato sauce.
Add the garlic, thyme, carrots, potatoes, and mushrooms to the slow cooker.
Gently pour your red wine sauce from the skillet, over the top of the veggies into the slow cooker.
Give it a stir, then cook on LOW for 8-10 hours or HIGH for 6-8.
Garnish with fresh parley and ENJOY!
