This is a minced lamb filling — spiced with cumin, cinnamon, mint, and parsley — layered with garlicky sautéed spinach and wrapped in puff pastry. The lamb is fully cooked before it goes into the oven, so the bake is really just about getting the pastry golden. That makes the whole thing faster and less stressful than it looks on the plate.
The short version of why this works
Two things carry this recipe. First, cooking the lamb filling completely before assembly means you’re not guessing at doneness — the oven time is purely for pastry, and puff pastry is forgiving in a way that beef tenderloin is not. Second, squeezing every bit of moisture out of the sautéed spinach before layering it in is non-negotiable. Wet spinach turns the pastry base soggy from the inside out, and no amount of high heat will fix that once it’s assembled. Press it hard in a clean towel or a fine-mesh sieve. Those two steps — fully cooked filling, bone-dry spinach — are what separate a clean slice from a collapsed mess.
Shopping notes
- Minced lamb: Look for 15–20% fat content. Leaner lamb dries out during the initial cook and the filling ends up crumbly rather than cohesive.
- Puff pastry: All-butter puff pastry browns more evenly and tastes better here. Most supermarket freezer sections carry it — just thaw it overnight in the fridge, not on the counter.
- Fresh mint: Dried mint is a reasonable swap in a pinch, but use about a third of the quantity — it’s more concentrated and can turn bitter if overdone.
- Cumin and cinnamon: These are standard pantry spices, but check that yours aren’t stale. Ground spices lose punch after about a year. If yours smell faint, use a little more.
If something goes sideways
- Pastry splits open during baking: The seam wasn’t sealed well enough, or the pastry warmed up too much before it went in. Next time, press the seam firmly with a fork and refrigerate the assembled roll for 15 minutes before baking.
- Bottom pastry is pale and doughy: Your baking sheet wasn’t hot enough. Preheat the sheet in the oven before placing the Wellington on it — the immediate heat from below helps the base crisp up.
- Filling slides out when slicing: The roll wasn’t chilled long enough after assembly, so the filling didn’t firm up. Let it rest 5–10 minutes out of the oven before cutting, and use a sharp serrated knife.
- Lamb filling tastes flat: Ground lamb needs assertive seasoning. If it tastes underseasoned after the initial cook, fix it before assembly — you can’t season the inside once it’s wrapped. Taste and adjust salt, then add a small squeeze of lemon if it needs brightness.
- Pastry browns too fast before the base is done: Tent loosely with foil for the last 10 minutes. Skip the garnish — not worth the extra dish — and just pull it when the base sounds hollow when tapped.
Keeping and reheating
Leftover Wellington keeps in the fridge for up to 3 days, wrapped tightly or in an airtight container. To reheat, put slices on a wire rack set over a baking sheet and warm them in a 350°F (175°C) oven for 12–15 minutes. The rack keeps air circulating underneath so the pastry crisps back up instead of steaming itself soft. The microwave works in a hurry but the pastry goes limp — acceptable for lunch, not great for guests. You can also freeze the fully assembled, unbaked Wellington for up to 6 weeks; bake straight from frozen at 400°F, adding about 15 minutes to the original bake time and checking that the pastry is deep golden before pulling it out.
Minced Lamb Wellington with Spinach
Equipment
Ingredients
For the Wellington Filling:
1 teaspoon cumin - ground
- 0.5 teaspoon black pepper - freshly cracked
- 0.5 teaspoon red chili flakes - optional, for a bit of heat
For the Spinach Layer:
For the Pastry and Assembly:
- 1 pound puff pastry - thawed if frozen, use all-butter variety
Instructions
- In a large skillet over medium heat, heat 1 tablespoon olive oil. Add the finely chopped onion and sauté for 5–6 minutes until soft and lightly golden.
- Add 3 cloves of minced garlic, and cook for 30 seconds until fragrant. Then add minced lamb, breaking it apart with a wooden spoon. Cook for 8–10 minutes until browned and cooked through.
- Drain off excess fat if needed. Stir in cumin, cinnamon, salt, pepper, mint, parsley, and (optional) chili flakes. Cook 2 more minutes, then remove from heat and cool to room temperature.
- In a separate skillet, heat 1 tablespoon olive oil. Add minced garlic and baby spinach and sauté for 2–3 minutes until wilted. Season with a pinch of salt. Remove and let cool completely.
- On a lightly floured surface, roll out the puff pastry to approximately 12x14 inches. Layer the spinach evenly in the center, followed by the cooled minced lamb mixture, shaping it into a uniform log.
- Fold the pastry over the filling, sealing the edges well. Place seam-side down on a parchment-lined baking tray. Score the top lightly for decoration and ventilation.
- Mix the egg and water to form an egg wash. Brush all over the pastry.
- Chill the prepared Wellington in the fridge for 20 minutes while you preheat your oven to 400°F (200°C).
- Bake for 40–45 minutes until the pastry is golden brown and crisp. If using a thermometer, internal temperature should read 160°F (71°C).
- Rest for 10 minutes before slicing and serving.
Notes
- For a leaner option, substitute ground lamb with ground turkey or beef.
- To save time, prepare the lamb and spinach fillings a day ahead and refrigerate before assembling.
- Consider adding a mushroom duxelle layer beneath the spinach for a more traditional Wellington twist.
- If puff pastry cracks while handling, dampen slightly with water and pinch together with your fingers.

Common questions
Can I assemble this the night before and bake it the next day?
Yes — assembling ahead is actually the better approach. Refrigerate the wrapped, egg-washed Wellington uncovered overnight and bake it straight from the fridge the next day. The cold pastry goes into the hot oven in better shape, which helps it puff evenly.
How do I know when the lamb filling is fully cooked during the initial sauté?
The lamb is done when it reaches an internal temperature of 160°F (71°C) and there’s no pink remaining. In practice, this takes about 8–10 minutes over medium-high heat, breaking the meat up as it cooks — but use a thermometer if you’re unsure rather than going by color alone.
Can I use shortcrust pastry instead of puff pastry?
You can, but the result is quite different — denser, less flaky, and it won’t give you that layered exterior. Shortcrust holds its shape well and won’t puff up around the seams, which some people actually prefer for cleaner slices.
My puff pastry sheet isn’t big enough to wrap the filling. What do I do?
Overlap two sheets slightly and press the join together firmly with your fingers, then seal it with a little egg wash. Roll the joined sheet gently with a rolling pin to even it out before you add the filling — the seam will hold as long as it’s well-pressed.
