Last updated on December 4th, 2025

Creating a beef Wellington doesn’t have to mean cooking for a crowd. This individual portion brings all the elegance of the classic dish to your personal dining experience. This recipe transforms a 3-ounce beef tenderloin into a golden-crusted masterpiece, perfect for special occasions or when you want to treat yourself.

Ingredients

Main Components:

• 3-ounce beef tenderloin
• 1/4 sheet puff pastry, thawed
• 1 slice prosciutto
• 1 teaspoon Dijon mustard
• 1 small egg, beaten (you’ll use about 1 tablespoon)

Mushroom Duxelles:

• 3 ounces mushrooms, finely chopped
• 1/4 shallot, minced
• 1 small garlic clove, minced
• 1 teaspoon fresh thyme
• 1 teaspoon butter
• Salt and pepper to taste

Note: Store remaining puff pastry and egg wash properly for future use.

Steps

Prepare the Duxelles (25 minutes):

• Heat a stainless steel or non-stick pan over medium heat. Add butter and wait until it’s fully melted and starting to foam.
• Add minced shallots and garlic. Cook for 2-3 minutes until translucent but not browned, stirring occasionally.
• Add finely chopped mushrooms and fresh thyme leaves. The mushrooms should be almost paste-like in consistency.
• Reduce heat to medium-low. Cook for 15-20 minutes, stirring every few minutes. The mixture will release liquid, and then slowly dry out.
• The duxelles is ready when it’s dark brown and concentrated, and no liquid remains when pressed with a spoon.
• Season with salt and pepper, then spread on a plate to cool completely (about 20 minutes).

Prepare the Beef (15 minutes):

• Remove tenderloin from the refrigerator 30 minutes before cooking.
• Pat dry with paper towels. Season generously with salt and freshly ground pepper on all sides.
• Heat a heavy-bottomed pan until smoking hot. Add a thin layer of high-heat oil.
• Sear the beef for exactly 90 seconds per side, including the ends, until uniformly browned.
• Remove from heat, brush immediately with Dijon mustard while hot.
• Place on a plate and refrigerate for 10 minutes to stop the cooking process.

Initial Assembly (10 minutes):

• Lay a 12-inch piece of plastic wrap on your work surface.
• Place prosciutto slice down, slightly overlapping if using multiple pieces.
• Using an offset spatula, spread cooled duxelles in a thin, even layer over the prosciutto.
• Position the mustard-coated beef in the center.
• Using plastic wrap as a guide, roll tightly, tucking in the ends.
• Twist the ends of the plastic wrap tightly to form a uniform cylinder.
• Refrigerate for 30 minutes minimum, up to 24 hours.

Final Assembly and Baking (35 minutes):

• Preheat oven to 400°F with rack in center position.
• Roll puff pastry on a lightly floured surface to 1/8-inch thickness.
• Remove plastic wrap from beef. Center on pastry.
• Fold pastry ends over beef first, then sides, sealing with water.
• Place seam-side down on the parchment-lined baking sheet.
• Brush the entire surface with a beaten egg. Create steam vents.
• Score diagonal lines in a decorative pattern, careful not to cut through.
• Bake 20-25 minutes until golden brown and internal temperature reaches 125°F.
• Rest 10 minutes before serving.

Tips and Tricks

• Ensure all components are cold before assembly to prevent the pastry from becoming soggy
• Pat mushrooms dry before chopping to reduce moisture
• Make clean cuts when scoring the pastry for the best appearance
• Use a meat thermometer for precise cooking
• Let the Wellington rest for 10 minutes before cutting
• Prepare components ahead for easier assembly

Present your personal Wellington on a warmed plate, sliced through the center to reveal the perfectly cooked interior. Traditional accompaniments include:

• A rich red wine reduction sauce
• Roasted baby vegetables tossed in herbs
• Tender asparagus spears
• Creamy garlic mashed potatoes
