These mini Beef Wellingtons give you seared beef tenderloin wrapped in mushroom duxelles, prosciutto, and puff pastry — two individual portions, done in about 30 minutes. The format is genuinely practical: individual parcels cook faster and more evenly than a full roast, and extras reheat well enough that making a double batch on the weekend pays off all week.
Why this recipe works
Two things actually drive the result here. First, cooking individual portions instead of one large roast means the pastry and the beef reach their ideal states at the same time — the pastry crisps before the meat overcooks. Second, the prosciutto layer does real work: it sits between the mushroom mixture and the pastry and blocks moisture from migrating in during baking. Without it, steam from the duxelles softens the pastry from the inside. With it, you get a clean, flaky shell every time.
Substitutions that actually work
- Beef tenderloin: Center-cut is the call here because it’s uniform in diameter, which matters for even cooking in a short window. Avoid substituting sirloin — it has too much connective tissue to cook through properly at this speed.
- Prosciutto: Thinly sliced Parma ham or speck both work. Avoid thicker deli ham — it traps steam rather than releasing it.
- Cremini mushrooms: White button mushrooms are a direct swap. Avoid portobello caps; they hold too much water and the duxelles won’t dry out fast enough.
- Dijon mustard: Whole-grain mustard works and adds a little texture. Skip the garnish of fresh herb sprigs on the plate — not worth the extra dish.
Keeping and reheating
Cooked Wellingtons keep in the fridge for up to 3 days in an airtight container. To reheat, put them on a wire rack set over a baking sheet and warm at 375°F for 10 to 12 minutes — the rack keeps air circulating underneath so the pastry bottom doesn’t go soggy. Avoid the microwave; it turns the pastry limp in under a minute. For longer storage, freeze assembled but unbaked parcels on a parchment-lined tray until solid, then transfer to a freezer bag; bake from frozen at 425°F for 25 to 28 minutes. Fully cooked and frozen Wellingtons are edible but the pastry texture suffers, so freeze them before baking if you’re planning ahead.
Troubleshooting
- Pastry splits open during baking: The seam wasn’t pressed firmly enough, or the pastry warmed up too much before it went in the oven. Chill the assembled parcels for 5 minutes before baking if your kitchen is warm.
- Beef is overcooked by the time the pastry is golden: The tenderloin medallions were too thin, or the sear ran too long. Aim for at least 1.5-inch-thick cuts and pull them from the pan the moment a crust forms — they finish in the oven.
- Wet, soft pastry on the bottom: The duxelles still had too much moisture when you spread it. After cooking the mushrooms, press them briefly against the side of the pan with a spatula and look for no liquid pooling at the bottom before you remove them from the heat.
- Prosciutto tears when wrapping: Cold prosciutto straight from the fridge is less pliable. Let it sit at room temperature for a few minutes and it will stretch without tearing.
- Egg wash looks patchy after baking: The wash was applied unevenly or the brush dragged across a seam and pulled it open. Use a light hand and a soft pastry brush, and don’t go back over the same spot twice.
30-Minute Mini Beef Wellingtons
Equipment
- Heavy skillet (10–12 inch)
- Tongs
- Baking sheet
- Parchment paper
- Rolling Pin
- Chef’s knife and cutting board
- Plastic wrap
- Pastry Brush
- Measuring cups and spoons
- Instant-read thermometer
- Food Processor (optional, for duxelles)
Ingredients
For the Beef & Sear:
- 12 oz center-cut beef tenderloin (filet mignon), divided into 2 fillets trimmed; 6 oz each
- 1 ¼ tsp kosher salt, divided use to season beef and duxelles
- ¾ tsp freshly ground black pepper divided
- 1 tbsp neutral oil grapeseed or canola
- 2 tbsp unsalted butter, divided for searing and duxelles
For the Duxelles:
- 8 oz cremini or button mushrooms, very finely chopped pulse in a food processor or mince by hand
- 1 small shallot, finely minced about 2 tbsp
- 2 cloves garlic, minced
- 1 tsp fresh thyme leaves or 1/4 tsp dried thyme
To Assemble & Finish:
- 2 tsp Dijon mustard
- 4 slices prosciutto thinly sliced
- 1 sheet frozen puff pastry, thawed 8–10 oz sheet, keep cold
- 1 large egg yolk for egg wash
- 1 tsp water for egg wash
- 1 tbsp all-purpose flour for dusting
- 1 pinch flaky sea salt optional, for finishing
Instructions
- Preheat and Prepare Tray: Position a rack in the center of the oven and preheat to 450°F (232°C). Line a baking sheet with parchment. Keep puff pastry chilled until needed for best flake.
- Season Beef: Pat the 12 oz beef dry. Season all sides with about 1 tsp kosher salt and 1/2 tsp black pepper. This early seasoning helps a deeper crust and better flavor.
- Sear Quickly: Heat a heavy skillet over medium-high until just smoking. Add 1 tbsp neutral oil, then the beef. Sear 60–75 seconds per side (about 3 minutes total), rolling briefly on edges to color all around. In the last 15 seconds, add 1 tbsp butter to foam and baste for a glossy crust. Transfer to a plate and brush each fillet with 1 tsp Dijon while warm. Set aside to cool slightly (2–3 minutes).
- Make Quick Duxelles: In the same skillet over medium heat, add remaining 1 tbsp butter, the minced mushrooms, and a pinch of kosher salt. Cook, stirring, until the pan looks dry and mushrooms smell nutty and concentrated, 4–5 minutes. Stir in shallot for 1 minute, then garlic and thyme for 30 seconds until aromatic. Grind in a little pepper. Spread the duxelles on a plate to cool quickly (1–2 minutes).
- Build the Prosciutto Wrap: Overlap 2 slices of prosciutto on a piece of plastic wrap to form a rectangle, repeat for the second portion. Divide the cooled duxelles over the prosciutto in a thin, even layer. Place a fillet on each, then use the plastic wrap to roll into a tight log, twisting the ends to secure. Chill in the freezer for 5 minutes to firm.
- Prepare Pastry: Lightly dust the counter with 1 tbsp flour. Roll the chilled puff pastry to about 1/8 inch thick. Cut two rectangles just large enough to enrobe each fillet with a 1-inch overlap. Whisk egg yolk with 1 tsp water for egg wash.
- Wrap and Seal: Unwrap a prosciutto log and place it seam-side down on a pastry rectangle. Brush edges with egg wash, fold pastry over, and press to seal tightly, trimming excess. Crimp edges with a fork if desired. Place seam-side down on the parchment-lined sheet. Repeat with the second. Brush tops with more egg wash, sprinkle with flaky sea salt (optional), and cut a small vent on top of each to release steam.
- Bake: Bake at 450°F (232°C) for 12–14 minutes, rotating the tray halfway, until pastry is deeply golden and an instant-read thermometer inserted into the center reads 125–130°F (52–54°C) for medium-rare.
- Serve: Transfer to plates. For the cleanest cut, slice once down the center to reveal rosy beef and a tight ring of duxelles. The pastry should shatter into crisp, buttery layers.
Notes
Jen’s Tips:
- Speed the Duxelles: Pulse mushrooms in a food processor to a fine mince; the dry-out step in the pan is key to avoid soggy pastry.
- Thermometer = Perfection: Pull at 125–130°F (52–54°C) for medium-rare; carryover heat will rise a few degrees.
- No Prosciutto? Use thin sliced ham. For a vegetarian twist, swap beef for thick roasted portobellos and layer with spinach.
- Mustard Swap: Try English mustard or horseradish cream for a brighter kick.
- Extra Crisp: Chill assembled Wellingtons 10 minutes if you have time; colder pastry = better puff and lamination.
- Gluten-free: Use a gluten-free puff pastry and verify prosciutto/condiments are GF.

Frequently asked questions
Can I make these ahead and bake them later?
Yes — assemble the parcels up to 24 hours ahead, cover them loosely with plastic wrap, and refrigerate unbaked. Pull them out while the oven preheats so the pastry isn’t ice-cold going in, which can slow browning.
What internal temperature should I pull the beef for medium-rare?
Pull the parcels from the oven when an instant-read thermometer reads 125°F to 130°F at the center of the beef. The temperature will climb a few degrees while the Wellingtons rest for the 5 minutes before slicing.
Do I have to use puff pastry from the freezer section, or can I use refrigerated?
Frozen all-butter puff pastry (like Dufour) gives the best result because the higher butter content produces more distinct layers. Refrigerated puff pastry works but tends to puff less dramatically and can taste a little bland by comparison.
Can I double the recipe to serve four?
Easily — just make sure all four parcels have enough space on the baking sheet so they aren’t touching. Crowding traps steam and slows browning on the sides.
My grocery store only sells whole beef tenderloin. How do I cut it for this recipe?
Ask the butcher to cut center-cut medallions for you, or do it yourself at home: trim the chain and tapered end, then cut the center section into rounds at least 1.5 inches thick. The tapered ends cook unevenly at high heat, so save those for a quick stir-fry another night.
