Ingredients
Scale
Beef and Seasoning
- 1 lb boneless beef sirloin steak
- 1 1/4 teaspoons salt
- 1/4 teaspoon pepper
Onions and Flavorings
- 1/4 cup butter
- 4 cups thinly sliced sweet onions (about 2 large onions)
- 3 tablespoons balsamic vinegar
- 2 teaspoons sugar
Broth and Vegetables
- 2/3 cup beef broth
- 2 medium red potatoes, thinly sliced (about 2 cups)
- 8 oz Brussels sprouts, trimmed and quartered (about 3 cups)
Cheese
- 1/2 cup shredded Gruyère cheese
Instructions
- Prepare the Steak: Cut the sirloin steak into thin strips. Season evenly with salt and pepper to enhance the meat’s flavor.
- Caramelize the Onions: Melt the butter in a large skillet over medium heat. Add the thinly sliced sweet onions and cook for about 10 minutes, stirring occasionally to prevent burning and encourage even browning.
- Add Vinegar and Sugar: Stir in the balsamic vinegar and sugar into the onions. Continue cooking for an additional 5-10 minutes, stirring occasionally, until the onions are deeply caramelized and tender.
- Sear the Steak: Push the caramelized onions to one side of the skillet. Add the seasoned steak strips to the cleared side. Cook for 3-5 minutes, turning occasionally, until the beef is nicely browned on all sides.
- Simmer with Vegetables: Pour in the beef broth to deglaze the skillet and incorporate all flavors. Add the thinly sliced red potatoes and quartered Brussels sprouts. Stir gently to combine, then cover the skillet and cook for 10-15 minutes, stirring occasionally, until the vegetables are tender and cooked through.
- Melt the Cheese & Serve: Sprinkle the shredded Gruyère cheese evenly over the top of the mixture. Cover the skillet for 1 minute to allow the cheese to melt. Serve immediately to enjoy the warm, cheesy topping alongside the savory beef and vegetables.
Notes
- If you prefer a stronger onion flavor, use a mix of sweet and yellow onions.
- For a vegetarian version, replace beef with mushrooms or plant-based meat substitutes and use vegetable broth.
- Add herbs like thyme or rosemary during the simmering stage for extra aroma and flavor.
- You can substitute Gruyère cheese with Swiss or mozzarella if desired.
- Ensure to slice the potatoes thinly so they cook fully within the simmering time.
