Servings: 4 servings
Ingredients
- 10 ounces beef tenderloin
- kosher salt
- fresh ground pepper
- 1 tablespoon olive oil
- 1 large vidalia onion sliced thin
- 6 ounces sliced mushrooms
- 1/4 cup beef stock
- 4 slices american cheese
- 1/2 cup prepared béarnaise sauce I use Knorr and prepare according to package directions
- 1 large ciabatta loaf sliced in half horizontally and the top hollowed out.
Instructions
- Preheat your grill.
- Season the tenderloin liberally with salt and pepper. Place the tenderloin on the grill and cook until desired degree of doneness. ( I like medium rare which takes about 3-4 minutes per side depending on how thick the steak is.) Transfer the steak to a plate and cover with foil. Allow to rest approximately 10 minutes.
- While the steak is resting, heat the olive oil in a large skillet over med-high heat. Add the onions to the pan and cook until softened. Add the mushrooms to the onions and cook until both are golden brown. Stir in the beef stock and deglaze scraping the bottom of the pan with a wooden spoon to loosen the brown bits. Cut the beef into bite sized pieces and add to the onion mixture. Stir to combine. Cover the beef mixture with the cheese making a cheese blanket of sorts and allow to melt. Stir in the béarnaise to coat the ingredients completely.
- Transfer the mixture to the bottom slice of bread. Place the top of the bread on the sandwich and cut into 4 equal pieces. Serve immediately.
