Heat a 10” (or larger) cast-iron skillet over medium-high heat. Add olive oil, followed by the beef in a single layer. Season generously with salt and pepper.
Cook until browned, about 1 minute on each side, then remove from the skillet and set aside. Cook beef in batches to avoid crowding the pan.
Reduce heat to medium, add butter, mushrooms, and onion to the pan, and cook, stirring occasionally, until softened, about 5-7 minutes. Add garlic and cook until fragrant, about 30 seconds.
Stir in beef stock, scraping up any browned bits from the bottom of the pan. Add in the dijon, Worcestershire sauce, and sour cream until smooth and creamy and sauce begins to thicken, about 5 minutes.
Serve over a bed of cauliflower rice or with any noodle replacement of choice.
