Ingredients You’ll Need
- 1 lb beef tenderloin or filet mignon
- 1 sheet puff pastry (thawed if frozen)
- 8 oz mushrooms, finely chopped
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 tablespoon Dijon mustard
- 1 tablespoon olive oil
- 1 egg (for egg wash)
- Salt and pepper, to taste
- Optional: fresh thyme or parsley
Mini Wellington portions work beautifully if you want individual servings.
Step-by-Step Instructions
- Prepare the beef.
Season the tenderloin generously with salt and pepper. Sear in a hot skillet with olive oil for 1–2 minutes per side. This locks in flavor and gives a nice crust. Let it cool slightly. - Make the mushroom duxelles.
In a skillet, sauté mushrooms, onion, and garlic until moisture evaporates and mixture is thick. Season with salt, pepper, and optional thyme. Let it cool. - Preheat the air fryer.
Set to 400°F (204°C) and preheat for 3–5 minutes. A hot air fryer ensures golden pastry. - Assemble the Wellington.
Roll out puff pastry on a lightly floured surface. Spread a thin layer of Dijon mustard over the beef. Spread mushroom mixture evenly. Wrap beef with puff pastry, sealing edges. Brush top with egg wash for shine. - Air fry the Wellington.
Place wrapped beef in the air fryer basket. Cook 15–18 minutes, until pastry is golden brown and beef reaches desired doneness:- Medium-rare: 130–135°F
- Medium: 135–145°F
- Rest before slicing.
Let it rest 5–10 minutes. This keeps the beef juicy and makes slicing cleaner. - Serve with flair.
Slice and serve on plates with pan sauce, vegetables, or mashed potatoes. Admire your fancy self.
Common Mistakes to Avoid
- Skipping the sear. The sear adds flavor and prevents soggy pastry.
- Overcrowding the basket. The pastry needs airflow to crisp.
- Rolling pastry too thin. Could tear during cooking.
- Skipping egg wash. Gives that perfect golden look.
- Cutting immediately. Resting is crucial for juicy beef.
Thinking “eh, it’s fine” is how soggy pastry happens.
Alternatives & Substitutions
- Mini Wellingtons: Perfect for appetizers or portion control.
- Vegetarian option: Use large portobello mushrooms or seitan fillets.
- Different fillings: Spinach, caramelized onions, or a smear of pate.
- Gluten-free pastry: Use store-bought GF puff pastry; cooking time may vary.
- Herb variations: Rosemary, sage, or tarragon elevate the flavor.
IMO, classic mushroom duxelles is hard to beat—but experiment if you want flair.
Tips for Perfect Air Fryer Beef Wellington
- Use a thermometer. Perfect doneness is key.
- Chill beef slightly before wrapping. Makes rolling easier.
- Don’t overstuff. Too much filling can make pastry soggy.
- Air fry in batches if needed. Crowding = uneven cooking.
- Serve immediately. Pastry is crispiest fresh out of the air fryer.
Bold tip: Brush edges of pastry with egg wash twice for extra golden crust.
