Ingredients

Beef
- 1 lb (450 g) beef tenderloin, trimmed and cut into 1.5-inch cubes
- Salt and pepper, to taste
- 1 tbsp olive oil
Mushroom Duxelles
- 8 oz (225 g) mushrooms, finely chopped
- 1 small shallot, minced
- 2 cloves garlic, minced
- 2 tsp fresh thyme leaves
- 1 tbsp unsalted butter
- Salt and pepper, to taste
Assembly & Pastry
- 1 sheet puff pastry, thawed
- 1 egg, beaten (for egg wash)
- 2 tsp Dijon mustard
- Fresh thyme or parsley, for garnish

Instructions

Prepare the Beef: Pat the beef cubes dry and season generously with salt and pepper. Heat olive oil in a skillet over medium-high heat. Sear the beef cubes for 1–2 minutes per side until browned but not cooked through. Remove and let cool.
Make the Mushroom Duxelles: In the same skillet, melt butter. Add shallots and garlic, sauté until translucent. Add mushrooms and thyme. Cook over medium heat until all moisture evaporates, about 8–10 minutes. Season with salt and pepper and let cool.
Prepare Puff Pastry: Roll out puff pastry on a lightly floured surface to smooth any creases. Cut into squares slightly larger than the beef cubes (roughly 2×2 inches).
Assemble Bites: Preheat oven to 400°F (200°C). Brush beef cubes lightly with Dijon mustard. Place a spoonful of mushroom duxelles in the center of each puff pastry square, then top with a beef cube. Fold pastry over to encase beef completely, pinching edges to seal. Place seam-side down on a parchment-lined baking sheet.
Egg Wash & Bake: Brush each puff pastry bite with beaten egg. Bake in preheated oven for 15–18 minutes or until pastry is golden brown and puffed. Let cool slightly before serving.
Serve & Garnish: Transfer bites to a serving platter. Garnish with fresh thyme or parsley. Serve warm.

Tips for Perfect Mini Beef Wellington Bites

Choose Quality Beef: Tenderloin is ideal due to its softness, but sirloin can work if budget-conscious.
Dry Mushrooms Thoroughly: Excess moisture will make puff pastry soggy. Cook until mixture is almost dry.
Keep Ingredients Cool: Puff pastry handles best when cold. Avoid over-handling.
Sear Quickly: You only need to brown the beef; cooking through will happen in the oven.
Make Ahead: Assemble bites ahead of time and store uncooked in the fridge; bake before serving.

Variations

Cheesy Twist: Add a small cube of Gruyère or Swiss cheese atop the duxelles before adding beef.
Mini Wellington Sliders: Serve the bites on small toasted buns with horseradish cream for a fun party variation.
Vegetarian Option: Substitute seared portobello mushroom pieces for beef, paired with a spinach duxelles.

Serving Suggestions

Dips & Sauces: Serve with horseradish cream, mustard aioli, or red wine reduction.
Side Pairings: Mini Beef Wellington Bites complement roasted vegetables, a fresh salad, or finger-friendly roasted potatoes.
Occasions: Perfect for cocktail parties, holiday buffets, or even as an appetizer before a full dinner course.
