Flaky, golden puff pastry wrapped around seared beef and savory mushroom duxelles — these Beef Wellington Bites take everything you love about the classic dish and shrink it down into a perfectly poppable package.

They look like you spent hours in the kitchen, but the whole thing comes together in just 35 minutes. Serve them at your next gathering and watch them disappear from the plate faster than you can say “I made those myself.”

Variations & Substitutions

Beef tenderloin is the classic pick here, but it can get pricey. Beef sirloin or even a well-trimmed strip steak works wonderfully and holds up great through the searing and baking process.

If you want to punch up the flavor even further, try swapping the Dijon for a horseradish cream spread — it adds a sharp, peppery contrast to the rich mushroom filling. You can also mix in a little pâté with the duxelles for an even more indulgent, traditional Wellington flavor profile.

Tips & Tricks for Perfect Results

Make sure your duxelles is completely dry before assembling. Any excess moisture will make the pastry soggy from the inside out. Cook those mushrooms low and slow until every last drop of liquid has cooked off.

Also, don’t skip the cooling step — wrapping hot filling in puff pastry will melt the fat layers before they hit the oven, which is what gives you those gorgeous, flaky layers.

Serving Suggestions

These bites are perfect as a passed appetizer at a dinner party, arranged on a wooden board alongside a small bowl of creamy horseradish dipping sauce or a red wine reduction. For a more casual spread, serve them alongside a crisp arugula salad dressed with lemon and shaved parmesan.

They also work really well as a fun centerpiece for a date night at home — plate them up with roasted asparagus and a glass of bold red wine for a restaurant-worthy meal without the reservation.

Equipment Needed

You don’t need any specialty tools to make these, just a few reliable kitchen staples that most home cooks already have on hand.

Sharp chef’s knife
Cutting board
Large skillet or cast iron pan
Baking sheet
Parchment paper
Pastry brush
Rolling pin
Cooling rack

Prep Ahead Tips

The duxelles can be made up to 3 days in advance and stored in an airtight container in the fridge. The beef can also be seared and refrigerated overnight. When you’re ready to bake, simply assemble, egg wash, and pop them straight into the oven.

You can even assemble the fully wrapped unbaked bites, freeze them on a tray, then transfer to a bag and bake from frozen at 400°F for 25–28 minutes.

Budget Tips

Beef tenderloin is a splurge, so if you’re watching your grocery bill, sirloin is a great stand-in at a fraction of the cost. Buying a whole block of puff pastry and cutting it yourself is more economical than pre-cut sheets.

Cremini mushrooms are budget-friendly and packed with savory depth — no need to reach for anything fancy. Fresh thyme can be replaced with dried (use half the amount) without sacrificing much flavor.

Storage & Reheating

Leftover bites can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, skip the microwave. Instead, pop them in a 375°F oven or air fryer for 8–10 minutes until the pastry crisps back up and the filling is warmed through.

If you froze the assembled unbaked bites, bake directly from frozen at 400°F for 25–28 minutes, adding a fresh egg wash before they go in for the best color and crunch.

Prep Time:15

Cook Time:20

Ingredients

1 lb beef tenderloin cut into 1-inch cubes
1 sheet puff pastry thawed
1 cup cremini mushrooms finely chopped (duxelles)
2 tablespoons Dijon mustard
2 tablespoons unsalted butter
2 cloves garlic minced
1 shallot finely diced
2 tablespoons fresh thyme leaves
Salt and black pepper to taste
1 egg beaten (for egg wash)
Flaky sea salt for topping

Instructions

Preheat your oven to 400°F and line a baking sheet with parchment paper.
Sear the beef. Season the beef cubes generously with salt and pepper. Heat a skillet over high heat with a drizzle of oil and sear each cube for about 30 seconds per side until browned. Set aside to cool.
Make the duxelles. In the same skillet, melt butter over medium heat. Add the shallot and garlic, cooking for 2 minutes until softened. Add the mushrooms and thyme, cooking until all moisture has evaporated, about 8–10 minutes. Season well and let cool completely.
Brush the beef. Once the seared beef cubes have cooled, brush each one with a thin layer of Dijon mustard.
Assemble the bites. Roll out your puff pastry on a lightly floured surface and cut into 3-inch squares. Place a small spoonful of duxelles in the center of each square, top with a beef cube, then fold the pastry up around it, pinching the seams firmly to seal.
Egg wash and bake. Place seam-side down on the prepared baking sheet. Brush each parcel with beaten egg and sprinkle with flaky sea salt. Bake for 18–20 minutes until deep golden brown.
Rest and serve. Let them sit for 5 minutes before serving — this keeps everything inside nice and contained.
