Mini Beef Wellingtons

The first time I attempted these mini beef wellingtons, it was for a New Year's Eve party and I was terrified they'd turn into dry hockey pucks. My kitchen smelled like butter and thyme for days afterward, which I now consider a victory. Those first few came out uneven, but watching guests bite through that golden pastry into the tender beef made all the anxiety worth it.

Last Christmas, my sister hovered over the baking sheet watching the pastry puff up through the oven door window. We were both convinced we would mess up the timing, but pulling out that tray of golden, browned beauties felt like a tiny culinary triumph. Now she requests them for every special occasion, and honestly I do not mind one bit.

Ingredients

• 8 beef tenderloin medallions (1.5–2 oz each): These should be about 1 inch thick for even cooking, and letting them come to room temperature before searing makes all the difference in texture
• Salt and freshly ground black pepper: Generously season the beef because the pastry will mute some of that seasoning
• 2 tbsp olive oil: Use an oil with a high smoke point since you are searing over high heat
• 8 oz cremini or button mushrooms, finely chopped: The finer you chop these, the better your duxelles will turn out—food processor helps immensely
• 2 tbsp unsalted butter: This carries the thyme flavor through the mushrooms
• 2 shallots, finely minced: Shallots bring a milder sweetness than onions that complements rather than competes with the beef
• 2 cloves garlic, minced: Fresh garlic makes the duxelles feel alive
• 2 tsp fresh thyme leaves, chopped: Dried thyme works but fresh gives you that bright, herbaceous punch
• 8 slices prosciutto: This adds a salty, savory layer between beef and mushrooms that ties everything together
• 1 sheet puff pastry (about 14 oz/400 g), thawed: Keep this cold until you are ready to wrap or it becomes a sticky mess
• 1 egg, beaten: This is what gives you that gorgeous restaurant worthy golden sheen

Instructions

Sear the beef medallions:

Season your beef generously with salt and pepper, then heat olive oil in a skillet over high heat. Sear each medallion for exactly 1 minute per side—you want a nice brown crust but the center should still be rare. Transfer to a plate and let them cool completely while you make the duxelles.

Cook the mushroom duxelles:

In that same skillet, melt butter over medium heat and sauté the shallots and garlic for about 2 minutes until fragrant. Add the chopped mushrooms and thyme, then cook until all the moisture has evaporated and the mixture turns into a concentrated, dark paste—about 8 to 10 minutes. Season with salt and pepper, then spread it out on a plate to cool completely.

Prepare the puff pastry:

Roll out your thawed puff pastry on a floured surface until it is about 1/8 inch thick. Cut it into 8 squares, each large enough to fully wrap around a beef medallion with some overlap for sealing.

Assemble each Wellington:

Lay a slice of prosciutto on each pastry square, then spread a spoonful of the cooled mushroom duxelles over the prosciutto. Place a seared beef medallion on top and fold the pastry over, pinching the seams tightly to seal. Place each one seam-side down on your parchment lined baking sheet.

Chill before baking:

Brush each pastry with the beaten egg, then pop the entire baking sheet in the fridge for 10 minutes. This chilling step helps the pastry hold its shape and puff beautifully.

Bake to golden perfection:

Bake at 400°F for 18 to 22 minutes until the pastry is deep golden brown and crisp. Let them rest for 5 minutes before serving—this allows the juices to redistribute and makes them easier to handle.

My friend actually cried when she bit into her first one, which was equal parts touching and hilarious. These have become the thing I make when I want someone to feel special without saying it outright.

Timing Is Everything

Having your duxelles completely cooled before wrapping is the difference between soggy pastry and crisp perfection. I once rushed this step and ended up with steaky, limp bottoms that still haunt me a little.

The Duxelles Secret

Most people give up on the mushrooms too early. You really need to cook them until they are dark, concentrated, and almost dry—that is where all the flavor hides.

Make Ahead Strategy

You can assemble these completely up to 4 hours ahead and keep them refrigerated, then brush with egg and bake right before serving. The pastry actually benefits from that extra chilling time.

• Leftovers reheat surprisingly well in a 350°F oven for about 10 minutes
• A dab of Dijon on the beef before wrapping adds a lovely sharp note
• These freeze assembled and unbaked for up to 2 weeks

Watch people is faces when they bite into that first layer of crispy pastry. That moment of quiet surprise is exactly why I keep making these year after year.
