Easy Beef Wellington

Preheat oven to 400°F (200°C). Cut puff pastry crosswise into 8 strips. Transfer strips to baking sheet, spacing 1-in. (2.5 cm) apart. Working with 1 strip at a time, hold ends with fingers and twist strip in opposite directions, forming a spiral. Press ends of strips onto baking sheet to prevent unraveling. Bake 15 minutes or until browned and puffed.

Meanwhile, season beef, if desired, with salt and pepper. Heat 1 Tbsp. (15 mL) oil in large nonstick skillet over medium-high heat. Reduce heat and cook steaks, turning once, to desired doneness, about 5 to 8 minutes (145°F/63°C for medium rare and 160°F/70°C for medium); remove steaks and keep warm.

Heat remaining 1 Tbsp. (15 mL) oil in same skillet over medium heat and cook mushrooms and shallot, stirring occasionally, until golden, about 8 minutes. Whisk together Knorr® Demi-Glace Classic Roast Gravy Mix and water in medium bowl and stir into skillet. Bring to a boil over medium-high heat. Reduce heat and cook until slightly thickened, about 1 minute.

Arrange steaks on serving plates. Spoon sauce over steaks and lean puff pastry twists on top. Serve, if desired, with cooked haricots verts.
