Ingredients:
- 1.5 lbs (680g) beef cubes, about 1 inch (2.5cm) in size, preferably chuck
- 1/4 cup (30g) all-purpose flour, plus more for dusting
- 1 tsp (5ml) kosher salt
- 1/2 tsp (2.5ml) freshly ground black pepper
- 2 tbsp (30ml) olive oil or vegetable oil
- 1 medium yellow onion, finely chopped
- 8 oz (227g) cremini mushrooms, sliced
- 2 cloves garlic, minced
- 1 cup (240ml) beef broth (low sodium preferred)
- 1/2 cup (120ml) dry sherry (optional, but highly recommended)
- 1 cup (240ml) sour cream (full-fat for maximum indulgence)
- 2 tbsp (30ml) Dijon mustard
- 1 tbsp (15ml) Worcestershire sauce
- 2 tbsp (30ml) chopped fresh parsley, for garnish
Instructions:
- Toss beef cubes with flour, salt, and pepper. Shake off excess flour.
- Heat oil in the large pot over medium-high heat. Brown beef in batches, avoiding overcrowding. Transfer browned beef to a plate.
- Add onion and mushrooms to the pot and sauté until softened and lightly browned, about 8-10 minutes. Add garlic and cook for another minute until fragrant.
- Pour in beef broth and sherry (if using), scraping up any browned bits from the bottom of the pot. Return beef to the pot. Bring to a simmer, then reduce heat to low, cover, and simmer for 1.5 hours, or until beef is very tender. Check periodically and add more broth if needed to prevent sticking.
- Remove pot from heat. Stir in sour cream, Dijon mustard, and Worcestershire sauce. Do not boil after adding sour cream, or it will curdle.
- Garnish with fresh parsley and serve immediately over egg noodles, rice, or mashed potatoes.
