Ingredients

  • 1 lb beef tenderloin or filet mignon, cut into 1-inch cubes
  • 2 tbsp olive oil
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 2 tbsp butter
  • 8 oz cremini or button mushrooms, finely chopped
  • 1 tsp fresh thyme leaves
  • 1 tbsp Dijon mustard
  • 1 sheet of puff pastry, thawed
  • 1 egg, beaten (for egg wash)
  • Flour, for dusting

Directions & Preparation

  1. Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
  2. In a skillet, heat the olive oil over medium-high heat. Add the beef cubes, seasoning them with salt and pepper. Sear the beef for about 2–3 minutes until browned but still rare in the center. Remove from the skillet and let it cool.
  3. In the same skillet, melt the butter and add the finely chopped mushrooms. Cook until the moisture evaporates and the mushrooms are golden brown, about 5–7 minutes. Stir in the thyme leaves and let it cool.
  4. Once the mushrooms have cooled, mix in the Dijon mustard and combine well with the beef cubes in a bowl.
  5. On a lightly floured surface, roll out the puff pastry to about 1/8 inch thick. Cut the pastry into squares that are about 3 inches on each side.
  6. Place a spoonful of the beef and mushroom mixture in the center of each pastry square. Fold the corners of the pastry over the filling, pinching to seal securely.
  7. Place the assembled bites on the prepared baking sheet. Brush the tops with the beaten egg to give them a golden color while baking.
  8. Bake in the preheated oven for 15–20 minutes, or until the pastry is puffed and golden brown. Remove from the oven and let cool slightly before serving.

FAQs

What can I do if the pastry doesn't puff up properly?

Ensure your oven is fully preheated and avoid opening the door during baking, as temperature fluctuations can affect puffing.

Can I use a different type of mushroom for the filling?

Yes, shiitake or portobello mushrooms can also work well, adding different flavors and textures.

How can I tell when the beef is cooked just right?

The beef should be seared on the outside but remain rare in the center; it will continue cooking in the oven.

What if my filling is too dry?

Add a small amount of beef broth or a splash of red wine to the mushroom mixture to add moisture.

Can I make these Bites larger for a more substantial appetizer?

Yes, you can cut the pastry squares larger, but adjust the cooking time accordingly to ensure the beef is fully cooked.

Is it possible to add cheese to the filling?

Absolutely! A bit of cream cheese or grated cheese can add a creamy texture to the filling.

What should I do if my egg wash is too thick?

If the egg wash is too thick, whisk in a small amount of water to thin it out for an even glaze.

Conclusion

Mini Beef Wellington Bites are not only a treat for the taste buds but also a feast for the eyes. Their sophisticated appearance makes them a standout dish for any occasion.

With a little preparation, these savory bites can elevate your gathering and impress your guests. Enjoy the delightful blend of flavors and the satisfaction of creating such a gourmet treat at home.

  1. Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

Notes

Additional serving suggestions: pair with a crisp salad, garlic bread, or roasted seasonal vegetables for balance.

For make-ahead, prep components separately and assemble just before heating to preserve texture.

Taste and adjust with acid (lemon/vinegar) and salt right at the end to wake up flavors.
