Mini beef fillets are seared and paired with a rich mushroom duxelles, then wrapped in flaky puff pastry with prosciutto. The assembly is brushed with egg wash for a golden finish and baked until crisp. Ideal for elegant appetizers or festive occasions, these bites bring savory depth with thyme and garlic enhancing the mushroom filling. Chilling before baking helps maintain a perfect texture, delivering a tender, juicy center complemented by a crisp outer layer.
The first time I attempted mini Wellingtons, I was rushing to prepare something impressive for last minute guests. My kitchen was chaos, pastry everywhere, but when those golden parcels emerged from the oven, suddenly the mess did not matter anymore.
Last Christmas Eve, my sister asked what smelled so incredible. The mushroom duxelles had been cooking down, filling the entire house with this deep, savory aroma that made everyone gather in the kitchen, wine glasses in hand, waiting for the first batch.
Ingredients
- Beef tenderloin medallions: Choose pieces cut to even thickness so they cook uniformly and stay tender inside
- Cremini or button mushrooms: These develop the most concentrated flavor when cooked down into a paste, forming the essential duxelles layer
- Unsalted butter: Allows you to control seasoning, and butter carries the thyme flavor through the mushrooms beautifully
- Puff pastry: Thaw completely but keep it chilled while working, otherwise it becomes impossible to fold and loses its signature flaky layers
- Prosciutto: Adds a salty, cured element that bridges the beef and mushroom flavors while keeping the pastry from getting soggy
Instructions
- Sear the beef:
- Get your skillet smoking hot, season the medallions generously, then sear each side for exactly one minute. You want a gorgeous brown crust while keeping the center rare since it will finish cooking in the oven.
- Make the duxelles:
- In the same pan, melt butter and cook shallots until soft, then add mushrooms and thyme. Keep cooking until all moisture evaporates and the mixture turns into a dark, concentrated paste, about 8 to 10 minutes.
- Prepare the pastry:
- Roll the puff pastry thin and cut eight squares. Keep everything cool, working quickly so the butter in the pastry stays cold, which guarantees those impressive flaky layers.
- Assemble each Wellington:
- Lay prosciutto on each pastry square, spread cooled duxelles over it, then place a seared beef medallion on top. Fold the pastry up and over, pinching tightly to seal.
- Chill before baking:
- Brush each parcel with beaten egg, then refrigerate for 10 minutes. This cold relaxes the gluten and helps the pastry puff dramatically in the oven instead of unraveling.
- Bake until golden:
- Bake at 400°F for 18 to 22 minutes, rotating halfway through, until the pastry is deeply golden and crisp. Let them rest for 5 minutes so the juices redistribute.
These have become my go to for dinner parties because I can assemble them hours ahead, keep them chilled, then pop them in the oven just as guests arrive. The smell alone makes people feel welcomed.
Working Ahead Like a Pro
The duxelles can be made two days ahead and refrigerated, actually developing deeper flavor. You can also assemble the entire Wellingtons, chill them on the baking sheet, then bake straight from the refrigerator, which might add a couple minutes to the baking time.
Choosing the Right Cut
Tenderloin is ideal because it cooks quickly and stays tender, but if you want to save money, a good sirloin cut into medallions works beautifully too. Just pound the sirloin slightly to even thickness so each piece cooks at the same rate.
Serving Suggestions That Wow
A simple red wine reduction takes two minutes and makes these feel restaurant worthy. Just simmer some red wine with a splash of beef stock until it thickens slightly, then drizzle over each plated Wellington.
- Pair with arugula dressed in lemon vinaigrette to cut through the richness
- Serve with roasted fingerling potatoes or a simple green salad
- These reheat surprisingly well at 350°F for about 8 minutes if you need to bake in advance
There is something deeply satisfying about cutting into that first Wellington and seeing the perfectly cooked beef inside. Hope these bring as many compliments to your table as they have to mine.
