Everything you need to know about making the most perfect Beef Stroganoff. Perfect for a rainy day!
- 4 tbsp. unsalted butter
- 2 tbsp. flour
- 1 tsp. dry mustard
- 1 cup beef stock
- ¼ cup sour cream
- 1 small yellow onion, thinly sliced
- 1½ lb. beef tenderloin, cut into 3″ x 1″ x ⅛″ slices
- Kosher salt and freshly ground black pepper, to taste
- Canola oil, for frying
- 4 russet potatoes, peeled and sliced into ⅛″ matchsticks
- 2 tbsp. finely chopped parsley
- Heat 2 tbsp. butter in a 2-qt. saucepan over medium heat. Add flour and dry mustard, and cook, stirring, for 2 minutes. Gradually add stock, whisking constantly, and bring to a boil; cook until thick, about 2 minutes. Stir in sour cream, remove from heat, and set aside.
- Heat remaining butter in a 12″ skillet over medium heat. Add onion, and cook until soft and lightly golden, about 5 minutes. Increase heat to high, add meat, and cook until just cooked through, about 3 minutes. Reduce heat to low, add reserved sauce, and season to taste with salt and pepper. Cover to keep warm.
- Meanwhile, pour oil to a depth of 1 1⁄2″ in a 4-qt. saucepan, and heat over medium heat until a deep-fry thermometer reads 365°. Working in batches, fry potatoes until golden and crisp, about 3 minutes. Drain on paper towels; season to taste with salt while still warm.
- Spoon stroganoff onto a serving platter, and cover with a mound of jumbled straw potatoes. Garnish with parsley.
