Description
For the Steaks:
1 lb ground beef
½ cup breadcrumbs
1 egg
1 tbsp Worcestershire sauce
1 tsp garlic powder
½ tsp salt
½ tsp black pepper
For the French Onion Sauce:
2 large onions, thinly sliced
2 tbsp unsalted butter
1 tbsp balsamic vinegar
2 cups beef broth
1 tbsp Worcestershire sauce
1 tsp dried thyme
1 tbsp cornstarch mixed with 2 tbsp water (for thickening)
4 oz Gruyère cheese, shredded
Directions:
In a large bowl, mix ground beef, breadcrumbs, egg, Worcestershire sauce, garlic powder, salt, and black pepper. Form into 4 oval-shaped patties.
Heat a skillet over medium-high heat and sear the patties for 2 minutes per side until browned. Transfer to the slow cooker.
In the same skillet, melt butter and sauté onions until caramelized, about 10 minutes. Deglaze with balsamic vinegar and stir well.
Pour onions over the patties in the slow cooker. Add beef broth, Worcestershire sauce, and dried thyme. Cover and cook on low for 4-5 hours.
Mix cornstarch with water, stir into the slow cooker, and cook for another 15 minutes until thickened.
Sprinkle Gruyère cheese over each steak, cover, and let melt for 5 minutes.
Serve warm with mashed potatoes or crusty bread. Enjoy!
