Ingredients
Servings
4
- 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 tbsp unsalted butter
- 1 tsp fresh thyme leaves
- 1/2 tsp salt, divided
- 1/4 tsp black pepper, divided
- 1 egg, beaten (for egg wash)
- Fresh parsley, finely chopped (optional, for garnish)
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.
Frequently Asked Questions
Reader questions and answers for this recipe will appear here.
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.
Air Fryer Model Notes
This Air Fryer Beef Wellington Bites recipe is crafted to deliver perfectly crisp, golden puff pastry and tender beef tenderloin. However, air fryer results can vary by model. Here are essential tips to ensure success:
- Basket Size and Shape: Smaller baskets may require batch cooking to avoid overcrowding, which can prevent even crisping. Larger air fryers or models with trays offer better air circulation for uniform browning.
- Temperature Accuracy: Some air fryers run hotter or cooler than their set temperature. Stick close to 400°F (200°C) but adjust cooking time slightly if your model cooks faster or slower to avoid under- or overcooking.
- Airflow Dynamics: Models with even heat distribution and strong fans cook more consistently. If you notice hotspots, rotate the basket halfway through cooking for best results.
- Preset Programs: Although some devices have presets, manual mode at 400°F for 10-12 minutes works best to achieve optimal doneness and crispiness in these bites.
- Multi-layer Racks: Avoid overlapping bites on multiple racks unless airflow is excellent. If using racks, extend cooking time slightly and check doneness often.
Following these tailored tips will help preserve the rich mushroom duxelles, tender beef, and flaky, crisp pastry—perfect for holidays and special family gatherings.
Crispiness Control
Achieving the perfect crispiness is key to an outstanding Air Fryer Beef Wellington Bite. Preheat your air fryer to 400°F (200°C) to ensure rapid crisping of the puff pastry while keeping the beef juicy.
For extra crisp exterior, keep puff pastry seams thin by trimming excess dough to promote even heat penetration. Generously brush each bite with beaten egg for that shiny, classic golden finish.
Arrange bites spaced apart in a single layer so hot air circulates freely. To soften the pastry, reduce cooking by 1-2 minutes but know this lowers crispiness.
Balancing crispness with tender beef wrapped in delicate pastry alongside rich mushroom duxelles makes monitoring cooking time important. Adjust based on your air fryer’s heat distribution for ideal texture every time.
Enjoy these crispy, family- and holiday-friendly bites that bring gourmet flavor and texture to your table.
Reheat In The Air Fryer
Reheat your Air Fryer Beef Wellington Bites while preserving their crisp puff pastry and juicy beef with these steps:
- Preheat the air fryer to 350°F (175°C) for 3-5 minutes.
- Arrange bites in a single layer without crowding to allow even heat circulation.
- Heat for 4-6 minutes, checking mid-way to avoid overcooking; pastry should regain crispness and beef warm through.
Additional tips:
- If refrigerated, add 1-2 minutes to reheating time.
- Reheat in batches if needed to maintain texture.
- Avoid reheating too long to keep beef tender.
- Optionally, brush bites lightly with beaten egg or melted butter before reheating for a refreshed golden finish.
This method keeps appetizers family-friendly and holiday-ready with convenience and high gourmet quality.
