Preheat the oven to 425 degrees F. Butter a 12-inch Dutch oven or large baking pan.
Remove the steaks from the icebox about 30 minutes before cooking. Sprinkle the steaks with Red River Ranch Original or salt and pepper.
In a large cast iron skillet, heat 1 tablespoon of olive oil over medium heat. Place the steaks in the skillet and cook for 3 minutes, then flip over and cook an additional 3 minutes. Remove the steaks from the skillet and set aside to cool slightly.
Return to the same skillet and add the butter and remaining 1 tablespoon of olive oil over medium heat. When the butter has melted, stir in the onion and mushrooms. Cook for about 10 minutes or until tender, stirring occasionally.
Stir in the garlic and flour until the flour is absorbed.
Stir in the wine and heavy cream and cook for about 3 minutes stirring constantly until the mixture thickens. Stir in the thyme.
Remove two biscuits from the can and mash them together to form one ball of dough. Place the dough on a lightly floured surface and roll out to about a 7-inch circle.
Add about 2 tablespoons of the mushroom soup in the middle of the dough circle then place a filet on top. Top with about 2 tablespoons of the soup.
Bring the corners of the dough together over the steak to meet in the middle. Note: if the dough doesn’t stick together you can brush with a little beaten egg to seal the dough. Place each Wellington, seam side down, into the Dutch oven or pan.
Bake 25 to 30 minutes or until golden brown and the meat reaches desired doneness (internal temperature for steak: Rare: 125°F Medium-Rare, 135°F medium, 140°F medium-well, 145°F).
