Ingredients
Scale
- 1 lb (450g) lean beef steak (such as flank steak or sirloin), thinly sliced
- 2 medium onions, thinly sliced
- 2 tablespoons olive oil
- 1 tablespoon butter
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried thyme (or 1 tablespoon fresh thyme, chopped)
- 1/2 cup shredded Swiss cheese (or Gruyère cheese)
- 1 tablespoon Dijon mustard
- Salt and pepper to taste
- Fresh parsley for garnish (optional)
- 1 tablespoon flour (optional, for thickening)
- 1/4 cup beef broth (optional, for added richness)
Ingredient Highlights
- Beef: Choose lean beef cuts like flank steak or sirloin for tender, flavorful rolls. These cuts are easy to slice thinly, which is key to making the roll-ups.
- Caramelized Onions: Onions are cooked slowly to bring out their natural sweetness, creating a rich, golden base that complements the beef beautifully.
- Swiss or Gruyère Cheese: These cheeses melt wonderfully, adding a creamy texture and a slightly nutty flavor that balances the richness of the beef.
- Dijon Mustard: A touch of Dijon mustard adds a hint of sharpness and depth to the flavor profile.
Instructions
Prepare the Ingredients for French Onion Beef Roll-Ups:
- Slice the Beef: Using a sharp knife, thinly slice the beef against the grain into strips about 1/4 inch thick. This helps the beef remain tender when cooked.
- Caramelize the Onions: Heat the olive oil and butter in a large skillet over medium heat. Add the sliced onions and cook them, stirring occasionally, for about 20-25 minutes. The onions should soften and turn golden brown. If they start to brown too quickly, reduce the heat to low. Stir in the garlic powder, onion powder, and dried thyme once the onions are caramelized, then season with salt and pepper to taste. Remove the onions from the pan and set them aside.
Assemble the Beef Roll-Ups:
- Prepare the Beef Roll-Ups: Lay the thinly sliced beef strips on a clean surface, such as a cutting board or large plate. Spread a thin layer of Dijon mustard on each slice of beef. Place a spoonful of the caramelized onions in the center, then top with a little shredded Swiss or Gruyère cheese.
- Roll the Beef: Carefully roll up each beef slice, securing it with toothpicks or kitchen twine. Repeat until all the beef slices are rolled up with the filling.
Cook the French Onion Beef Roll-Ups:
- Sear the Beef Roll-Ups: Heat a little more olive oil in the same skillet over medium-high heat. Sear the beef roll-ups for about 2-3 minutes on each side, or until the beef is browned and the cheese inside starts to melt. Be careful not to overcrowd the pan; cook in batches if necessary.
- Optional Sauce: If desired, remove the roll-ups from the skillet and set them aside. In the same skillet, add a tablespoon of flour and stir to form a roux. Gradually add 1/4 cup of beef broth, stirring constantly to prevent lumps. Cook the sauce for a few minutes until it thickens, then pour it over the beef roll-ups for an extra layer of flavor.
- Finish Cooking: Reduce the heat to medium-low and return the beef roll-ups to the pan. Cover the pan with a lid and cook for an additional 5-10 minutes, allowing the beef to finish cooking through and the cheese to fully melt.
Serve:
- Garnish and Serve: Once cooked, remove the toothpicks or twine from the roll-ups. Transfer the French Onion Beef Roll-Ups to a serving platter and garnish with fresh parsley, if desired. Serve hot with your favorite side dishes.
