Beef Wellington Dijon Bites

Mini beef Wellington bites are a crowd-pleasing appetizer that looks elegant on a party platter but is approachable enough for home cooks. Each bite layers buttery puff pastry with tender beef, umami-packed mushroom duxelles, and crispy prosciutto, then finishes with a zingy Dijon sauce. These are the perfect starter for holidays or gatherings when you want to impress without spending the whole day in the kitchen.

The first time I made these, everyone hovered around the kitchen waiting for a taste. Watching people close their eyes for that first bite made the prep totally worth it.

Ingredients

• Dijon mustard: adds tang and sharp flavor Choose a smooth Dijon for best dipping consistency
• Sour cream: balances with creaminess Pick a full fat option if possible for the richest texture
• Mayonnaise: rounds out the sauce Avoid light mayo for best flavor
• Garlic: fresh cloves make a world of difference Look for plump firm bulbs
• Kosher salt: enhances all other flavors Flaky salt works too
• Mushrooms: white button or cremini bring that deep umami Flavor improves with fresher mushrooms so choose ones without dark spots
• Shallots: add a soft sweet onion note Pick heavy shallots without sprouting
• Rosemary: offers a woodsy note Fresh rosemary is far bolder than dried
• Dry red wine: deepens the duxelles Use whatever you like to drink for good results
• Prosciutto: adds savory and salty punch Look for slices with minimal fat for ease of chopping
• Puff pastry: creates that classic flaky base Buy an all butter brand if you can find it in the freezer aisle
• All purpose flour: keeps pastry from sticking during rolling
• Egg: creates golden shine on the pastry
• Beef tenderloin: is tender and luxurious Ask your butcher to cut a center portion for even cubes
• Neutral oil: helps with high heat searing and flavorless options like canola or avocado oil are ideal
• Fresh chives: are the prettiest pop of green Pick bunches that are brightly colored all the way through

Instructions

Dijon Sauce:

Whisk Dijon mustard, sour cream, mayonnaise, and minced garlic in a small bowl with a pinch of salt. Keep whisking until totally smooth. Taste and add more salt if needed, then cover and chill for later.

Prep the oven and workspace:

Set your oven to 400 degrees and line two sheet pans with parchment. Grab your food processor and rolling pin.

Chop the mushrooms mixture:

In the processor, add mushrooms, shallots, and two garlic cloves. Pulse in short bursts until no large pieces remain. Stop and scrape the sides a couple times to get a fine mince.

Make the mushroom duxelles:

Heat one tablespoon butter in a large pan over medium. Stir in the chopped mushroom mix. Cook slowly, stirring often, until it becomes a thick paste and looks dry. Season with rosemary, salt, and pepper, then stir an extra thirty seconds.

Deglaze and finish duxelles:

Pour in red wine. Stir and simmer until nearly all liquid is gone. The pan should be mostly dry. Turn off the heat. Transfer the paste to a bowl. Mix in the chopped prosciutto thoroughly. Let the mixture cool fully before next steps.

Roll and cut pastry:

Lightly dust work surface with flour. Roll out puff pastry to a ten by ten inch square. Use a sharp knife or bench scraper to cut into twenty five two inch squares. Arrange the squares a couple inches apart on sheet pans and prick the center with a fork.

Egg wash and assemble bases:

Beat egg with a splash of water. Brush over pastry squares. Top each square with one tablespoon cooled duxelles and lightly flatten.

Bake the pastry:

Slide pans into the oven and bake fifteen or sixteen minutes until puffed and golden brown. Cool on a rack while prepping beef.

Sear the beef cubes:

Pat beef cubes dry with a paper towel. Season generously with salt and black pepper. Heat neutral oil in the same pan you used for duxelles over medium high. When hot, add beef chunks and sear each side until crust forms but centers stay pink, about one to two minutes max.

Butter bastes and herbs:

Add remaining butter, the last garlic clove, and additional rosemary to the pan. Stir and toss beef cubes in melted butter and herb mixture for another one to two minutes until shiny and fragrant. Quickly move beef to a plate so it does not overcook.

Assemble the bites:

Place a seared beef cube on each pastry square. Top each with a dollop of chilled Dijon sauce. Sprinkle chives over all to garnish. Serve as soon as possible for maximum crispness.

I have always loved using beef tenderloin in appetizers because every bite feels so rich but the prep is actually fairly hands off. The aroma of the mushroom duxelles cooking is enough to draw everyone into the kitchen.

Storage Tips

Let baked pastries and cooked beef cool separately before storing. Keep in airtight containers in the fridge up to two days. Reheat briefly in a hot oven to refresh the crisp texture of the pastry before serving. The Dijon sauce will keep up to three days in the fridge—just give it a good stir.

Ingredient Substitutions

If you cannot find tenderloin try center cut sirloin for a slightly more affordable but still tender option. Diced ham works instead of prosciutto in a pinch. Cremini and button mushrooms are both great but portobellos are another choice for a stronger flavor. For the dipping sauce try switching dijon mustard for whole grain or a mix with honey for a sweeter dip.

Serving Suggestions

Pile these beef wellington bites onto a big white platter clustered tightly so guests can grab and go. Pair with something fresh like a crisp green salad or chilled white wine to balance the richness. They are also amazing as the main event of a cocktail hour with other hand held snacks.

Cultural and Historical Context

Beef Wellington is a classic English showstopper often served at special occasions but these bites shrink the drama to finger food size. Puff pastry is a staple in French patisserie traditions and duxelles has roots stretching back to classic French kitchens. Combining everything into a single bite has updated an old favorite for busy modern cooks.

Seasonal Adaptations

Spring mushrooms add a lighter flavor. Winter beef and pastry is extra comforting during the holiday season. Chives can be swapped for microgreens in the summer for freshness.

Success Stories

One Christmas Eve I doubled the batch and still had guests hovering for seconds before I could even refill the platter. Kids and adults both love them for the flaky crust and tender meat wrapped inside.

Freezer Meal Conversion

Bake the pastry shells and cook beef cubes as normal Let everything cool fully Store the elements separately and freeze. When ready to serve, reheat the pastry in a very hot oven and gently warm the beef cubes just until hot. Assemble and top with fresh chives for a just baked effect.

With these mini beef Wellington bites, you can serve classic flavor in an elegant, party friendly way. They are sure to become the star of your next gathering.
