Instructions
In a large skillet, saute onions and mushrooms in about 1/4 cup of beef stock over medium heat. Add stock as it evaporates to keep vegetables from sticking to the pan.
Once onion and mushroom are tender, add in raw ground beef, garlic and black pepper. Saute until meat is thoroughly cooked.
Add 2 cups of beef stock to the mixture and bring to a light simmer. In a glass jar, mix milk with flour and shake vigorously to combine. Slowly stir into beef mixture until all is combined.
Simmer on medium for 3-5 minutes, allowing flour to react. Turn heat to low and allow sauce to thicken.
