Mini Beef Wellingtons Delight

The smell of golden puff pastry hitting the oven still makes my kitchen feel like a fancy restaurant. I first made these mini Wellingtons for a New Year's Eve party, nervously checking the oven every three minutes, convinced they would collapse. They came out puffed and gorgeous, and my friend Sarah actually asked if I had secretly ordered them from a caterer.

Last Christmas, my dad stood by the stove watching me sear the beef, asking why I would not just cook it all the way through right then. When I explained that the meat would finish cooking inside the pastry, he looked skeptical. That same dad went back for thirds and told me I had cracked the code to tender beef.

Ingredients

• 8 beef tenderloin medallions: These 1-inch thick cuts are the perfect size for individual Wellingtons, about 1.5 oz each
• Salt and freshly ground black pepper: Generous seasoning on the beef before searing creates a flavor foundation
• 1 tbsp olive oil: High smoke point oil is essential for getting that proper sear without burning
• 8 oz cremini or button mushrooms: Finely chopped mushrooms become the most incredible concentrated paste when cooked down
• 1 small shallot: Shallots give a sweeter, more delicate flavor than onions in the duxelles
• 2 cloves garlic: Minced fresh garlic adds aromatic depth to the mushroom mixture
• 2 tbsp unsalted butter: Butter helps cook down the mushrooms and creates that luxurious paste consistency
• 1 tbsp fresh thyme leaves: Thyme pairs beautifully with beef and mushrooms
• 1 tbsp fresh parsley: Added at the end for fresh brightness and color
• 1 sheet all-butter puff pastry: All-butter pastry browns better and tastes far superior to shortening versions
• 4 slices prosciutto or Parma ham: The salty prosciutto acts as a flavor barrier and keeps everything moist
• 1 egg: Beaten egg wash creates that gorgeous golden shine on the baked pastry
• Flour: Just enough for dusting your work surface when rolling the pastry

Instructions

Sear the beef medallions:

Pat each medallion completely dry with paper towels, then season generously with salt and pepper on all sides. Heat olive oil in a skillet over high heat until nearly smoking, then sear beef for just 30 seconds per side until a beautiful brown crust forms. Transfer to a plate and let cool completely, resisting the urge to cook through.

Prepare the mushroom duxelles:

In the same skillet, melt butter over medium heat and add the minced shallot and garlic, sautéing for 1 minute until fragrant. Add the finely chopped mushrooms and thyme, cooking and stirring often until all the liquid evaporates and the mixture becomes a thick, concentrated paste, about 8 minutes. Season with salt, pepper, and stir in the parsley, then cool completely.

Roll and cut the pastry:

On a lightly floured surface, roll out the puff pastry to 1/8-inch thickness, keeping it as even as possible. Cut into 8 equal squares, working quickly so the pastry stays cold.

Assemble the Wellingtons:

Lay a halved slice of prosciutto on each pastry square, then spread a spoonful of the cooled mushroom duxelles over the prosciutto. Place one cooled beef medallion in the center of each square.

Wrap and seal:

Fold the pastry corners over the beef, pressing edges together and sealing with a little of the beaten egg wash. Place each Wellington seam-side down on a parchment-lined baking sheet.

Chill and prep for baking:

Brush the tops of each Wellington with egg wash, then refrigerate for 10 minutes to firm up the pastry. Preheat your oven to 400°F while they chill.

Bake to golden perfection:

Bake for 18 to 22 minutes until the pastry is deep golden brown and puffed beautifully. Let rest for 5 minutes before serving, which allows the juices to redistribute.

These have become my go-to when I want to serve something that feels special without spending hours in the kitchen. My sister actually requested them for her birthday dinner instead of a traditional cake, which I took as the highest compliment.

You can assemble these Wellingtons up to 4 hours before baking, cover them tightly, and keep them refrigerated. Brush with egg wash just before baking, not ahead of time.

A simple red wine reduction or demi-glace takes these over the top, and they pair wonderfully with roasted asparagus or a crisp green salad. Medium-bodied red wines like Pinot Noir complement the rich beef beautifully.

If your pastry is not browning evenly, rotate the baking sheet halfway through baking. For extra golden color, you can do a second egg wash halfway through the cooking time.

• Pat the beef very dry before searing for the best crust
• Really finely chop the mushrooms for the proper duxelles texture
• Let the Wellingtons rest before cutting or the juices will run out

There is something deeply satisfying about cutting into that first Wellington and seeing the perfectly pink beef inside. Watch your guests faces when they take that first bite.

Recipe Help & Support

→ What cut of beef is best for this dish?

Tenderloin medallions are ideal for their tenderness and uniform thickness, ensuring even cooking inside the pastry.

→ How is the mushroom duxelles prepared?

Finely chopped mushrooms are sautéed with shallots, garlic, butter, and fresh herbs until moisture evaporates, creating a smooth, flavorful paste.

→ Can prosciutto be substituted or omitted?

Yes, thinly sliced ham can replace prosciutto, or it may be omitted for a lighter version without compromising taste.

→ Why is the beef seared briefly before baking?

Quick searing locks in juices and imparts a brown crust, enhancing flavor while the beef finishes cooking inside the pastry.

→ What serving suggestions complement these mini wellingtons?

They pair well with a medium-bodied red wine like Pinot Noir and sauces such as red wine reduction or classic demi-glace.
