How do I keep this recipe from turning soggy?

Cook in a single layer, leave space for airflow, and avoid adding too much oil or sauce before the food has crisped.

Can I adjust the seasoning?

Yes. Keep the same cooking method and adjust salt, spice, herbs, citrus, or sauce to match your taste.

How do I know the beef tenderloin is done?

Use the visual cues in the instructions first: the outside should be browned or crisp and the center should be hot and tender. For meat or seafood, confirm doneness with a food thermometer.

12 oz beef tenderloin, cut into 1-inch cubes
1 sheet puff pastry (thawed if frozen), cut into 12 equal squares
8 oz cremini mushrooms, finely chopped
1 small shallot, minced
2 cloves garlic, minced
1 tbsp olive oil

1/4 tsp black pepper, divided
1 egg, beaten (for egg wash)
Fresh parsley, finely chopped (optional, for garnish)

Ingredients for Air Fryer Beef Wellington Bites with Mushroom Duxelles

Instructions

In a medium skillet over medium heat, melt butter with olive oil. Add the minced shallot and garlic, sautéing until fragrant and translucent, about 2 minutes.
Add the finely chopped mushrooms and thyme leaves to the skillet. Cook, stirring occasionally, until the mushrooms release their moisture and it evaporates, and the mixture becomes thick and paste-like—about 8-10 minutes. Season with 1/4 tsp salt and 1/8 tsp pepper. Remove from heat and let cool completely.
Season beef tenderloin cubes evenly with the remaining salt and pepper.
Preheat your air fryer to 400°F (200°C) for 5 minutes.
Lay out the puff pastry squares on a clean surface. Spread about 1 tsp of the cooled mushroom duxelles onto each square, leaving the edges clear.
Place a cube of beef tenderloin in the center of each puff pastry square atop the mushroom duxelles.
Fold the puff pastry over the beef to enclose it completely, pinching and sealing the edges well. Gently shape each into a bite-sized parcel. If necessary, trim excess pastry to avoid too thick edges.
Brush each pastry-wrapped beef bite generously with beaten egg to achieve a golden, glossy finish during cooking.
Arrange the bites in a single layer inside the air fryer basket, making sure they do not touch. Cook for 10-12 minutes, or until the pastry is golden brown and crisp, and the beef reaches your desired doneness (medium-rare recommended).
Remove the bites carefully with a spatula; let rest for 3 minutes.
Optionally, garnish with finely chopped fresh parsley before serving. Enjoy these savory, crisp Beef Wellington bites as an elegant holiday appetizer or a special family-friendly snack.

Tips

Air Fryer Model Notes

Cook Air Fryer Beef Wellington Bites with Mushroom Duxelles in a single layer when possible. Basket models may need batches; oven-style models may need a tray rotation halfway through for even browning.

Crispiness Control

Pat the beef tenderloin dry, avoid crowding, and use only a light coat of oil or sauce before cooking. Add wet sauces near the end when you want the outside to stay crisp.

Doneness Cues

Look for browned edges, a hot center, and the texture described in the instructions. For meat or seafood, confirm doneness with a thermometer instead of relying only on color.

Reheat In The Air Fryer

Reheat leftovers at 325 F to 350 F in a single layer until hot and crisp again. Add fresh herbs, citrus, or sauce after reheating.

Can I make Air Fryer Beef Wellington Bites with Mushroom Duxelles ahead of time?: You can prep the ingredients and seasoning ahead, but air fry close to serving for the best texture.

Ingredient Replacements

Customize your Air Fryer Beef Wellington Bites easily to accommodate dietary preferences or ingredient availability:

Beef Tenderloin: Swap for filet mignon or sirloin tips as budget-friendly options. For vegetarian or vegan versions, use large portobello mushroom caps instead of beef.
Puff Pastry: Use gluten-free puff pastry for gluten-free diets. For a low-carb alternative, wrap beef in thinly sliced zucchini or eggplant strips.
Mushroom Duxelles: Substitute cremini mushrooms with shiitake or button mushrooms. For dairy-free, omit butter and increase olive oil.
Shallots and Garlic: Yellow onions replace shallots; garlic powder is acceptable if fresh garlic isn’t available.
Butter: Use plant-based margarine or olive oil for dairy-free or vegan options.
Egg Wash: Replace with aquafaba or a mixture of plant milk and maple syrup for an egg-free or vegan golden glaze.

These substitutions keep your recipe aligned with family-friendly, holiday, and gourmet occasions without compromising savory taste or texture.

Storage

Store leftover Air Fryer Beef Wellington Bites with Mushroom Duxelles in an airtight container in the refrigerator for up to 3 days. Cool the food before sealing so excess steam does not soften the texture.

Freeze only if the main ingredient and coating are freezer-friendly. Wrap tightly and freeze for up to 1 month, then thaw overnight in the refrigerator before reheating.

Reheat in the air fryer at 325 F to 350 F in a single layer until hot and crisp again. Add fresh herbs, citrus, or sauce after reheating for the best flavor.
