Method
- Preheat oven to 425°F and line a baking sheet with parchment paper.
- In a large bowl, whisk together flour, baking powder, salt, and sugar until combined.
- Cut cold butter into flour mixture using pastry cutter until mixture resembles coarse crumbs.
- Pour cold buttermilk into flour mixture and stir gently just until dough comes together.
- Turn dough onto floured surface, pat into 1-inch thick rectangle, and cut into 8 biscuits.
- Place biscuits on prepared baking sheet and bake 15-18 minutes until golden brown.
- Heat olive oil in large skillet over medium heat and cook sliced onions until caramelized, about 15 minutes.
- In saucepan, combine beef broth, wine, garlic, Worcestershire sauce, and thyme. Simmer 10 minutes.
- Warm sliced roast beef in au jus for 2-3 minutes, then remove and strain the au jus.
- Split warm biscuits, layer with cheese, beef, and caramelized onions. Serve with warm au jus for dipping.
Notes
For best results, keep butter and buttermilk cold until use. Biscuits are best served immediately but can be reheated in a 350°F oven. Au jus can be made ahead and reheated.
