Main Ingredients

2 pounds beef steak (e.g., sirloin or flank) Choose a cut that you prefer.
8 ounces mushrooms, sliced Any variety of mushrooms can be used.
1 cup brandy (optional; can substitute with broth) Brandy adds depth of flavor, but broth works well too.
1 medium onion, chopped Use a yellow or white onion for sweet flavor.
4 cloves garlic, minced Adjust garlic according to taste.
2 cups beef broth Low sodium recommended.
2 tablespoons Worcestershire sauce This adds umami to the dish.

Method

Preparation

Season the beef: Generously season the beef steak with salt and pepper.
Sear the steak: In a skillet over medium-high heat, sear the steak on both sides until it’s beautifully browned.
Sauté the vegetables: Remove the steak and set it aside. In the same skillet, sauté the onions and garlic until fragrant. Add the sliced mushrooms and cook until soft.
Deglaze the pan: Pour in the brandy, scraping the bottom of the skillet to release any tasty bits. Let it simmer for a few minutes.
Combine in the slow cooker: Add beef broth and Worcestershire sauce to the skillet, mix well, and pour over the seared steak in the slow cooker.
Slow cook: Cover and cook on low for 6-8 hours.
Garnish and serve: Garnish with freshly chopped parsley and enjoy.

Notes

For thicker sauce, mix 1 tablespoon of cornstarch with cold water and add to the slow cooker about 30 minutes before serving. Consider adding more vegetables for added nutrition.
