Instant Pot Duck and Cauliflower Quiche

What the Pressure Does

Cut into it and the custard holds its shape for exactly a moment before yielding — not collapsing, not running, but giving in the way a well-set panna cotta does when a spoon disturbs it. The top is pale gold where the egg has just set against the pan, slightly darker at the edge where the pastry meets the filling. Underneath, pulled duck — dark, shredded, faintly sweet from the fat it rendered in — threads through a cauliflower filling that has gone tender and nutty from the Instant Pot’s pressurised heat. The whole thing smells of thyme, of rendered bird, of something that took time even though it didn’t.

This is Instant Pot duck and cauliflower quiche: a pressure-cooked savoury tart built around a filling of braised duck leg and cauliflower florets, held together by a thyme-and-gruyère custard and baked — or in this case, steamed under pressure — in a springform pan that sits directly in the Instant Pot’s ceramic insert. The result is a quiche with a more yielding, almost trembling interior than an oven-baked version, and a duck filling that would take two hours on the stovetop but needs only forty minutes in the pot.

It is not the fastest thing you will cook this week. It is the one that people will ask about.

The Case for Doing This Properly

Quiche has a reputation problem — it tends to arrive either waterlogged and rubbery, or dry enough to crumble. The Instant Pot changes the equation. The pressurised, steam-rich environment cooks the custard at a lower effective temperature than a conventional oven, producing a set that is uniformly silky from edge to centre without the dried-out band that forms when the outside of a quiche overcooks while the middle catches up. This is the same logic that makes pressure-cooked cheesecake a revelation — controlled, gentle, moist heat produces a texture that dry oven heat simply cannot replicate.

The duck component earns its place because duck leg is one of the most forgiving proteins in a pressure cooker. The high collagen content of the leg — the same connective tissue that requires hours of slow cooking in a conventional braise — converts to gelatin under pressure in under thirty minutes, producing meat that shreds cleanly and carries enough body to hold its own against the richness of the egg custard. Cauliflower is there not as a health amendment but as a structural and flavour counterpart: roasted briefly before it goes into the filling, it develops a nuttiness that mirrors the duck’s richness without competing with it.

Make this for a late Sunday lunch, a dinner party that wants to seem effortless, or any occasion that calls for something that looks like it required a great deal more planning than it did.

Everything on the Counter

For the duck

• 2 duck legs (about 700g total) — bone-in, skin on. The skin renders fat into the pot; removing it before cooking produces drier, less flavourful meat. You will remove the skin and shred the flesh after cooking
• 1 tsp fine salt
• ½ tsp black pepper, freshly ground
• 2 tbsp duck fat or neutral oil
• 2 garlic cloves, smashed
• 3 sprigs fresh thyme
• 120ml chicken stock — unsalted or low-sodium; the duck will concentrate it significantly under pressure

For the cauliflower

• 300g cauliflower florets, cut into small pieces no larger than 2cm — larger pieces will not cook evenly in the custard
• 1 tbsp olive oil
• Pinch of salt

For the custard and pastry

• 1 sheet ready-rolled shortcrust pastry (230–250g) — or homemade blind-baked in a 18cm springform pan. Store-bought works well here; the Instant Pot’s steam does not produce a crisp bottom crust regardless, so an artisan pastry offers diminishing returns
• 4 large eggs
• 200ml double cream — single cream produces a looser set; the quiche will be softer and less sliceable
• 80g Gruyère, grated — Emmental is a workable substitute with a milder result; sharp cheddar produces a more assertive, less classical flavour that still works well with the duck
• 1 tsp fresh thyme leaves
• ½ tsp fine salt
• ¼ tsp white pepper
• Pinch of ground nutmeg

On equipment: you need a 6-quart or larger Instant Pot, an 18cm (7-inch) springform pan that fits inside the insert with room for the trivet, and enough aluminium foil to create a sling for lowering and lifting the pan. Do not attempt this in a smaller pot — the pan will not fit.

The Method, Step by Step

1. Brown the duck legs. Pat the legs thoroughly dry — wet skin steams rather than renders. Season all over with salt and pepper. Set the Instant Pot to Sauté (high) and add the duck fat or oil. When the surface shimmers and a drop of water skitters across it, lay the duck legs skin-side down. Leave them entirely undisturbed for 6–8 minutes. You want the skin golden-brown and reduced, pulling away from the pan without force. Flip and brown the flesh side for 2 minutes. Transfer to a plate.
2. Build the braise. Add the garlic and thyme to the rendered fat in the pot. Let them sizzle for 30 seconds — the thyme will crackle. Pour in the chicken stock and scrape the bottom of the insert with a wooden spoon; the brown fond that clings there is flavour that must be released or it will trigger a burn warning. Return the duck legs to the pot, skin-side up. Seal the lid, set the valve to Sealing, and pressure cook on High for 28 minutes. Natural release for 15 minutes, then quick release any remaining pressure.
3. Shred the duck. Lift the legs from the pot and let them cool enough to handle. Discard the skin and pull the meat from the bone in rough, uneven pieces — irregular shreds hold dressing and custard better than uniform strips. Reserve 2 tablespoons of the braising liquid; discard the rest or save it for stock. The meat should be dark, yielding, and faintly gelatinous at the edges.
4. Roast the cauliflower. While the duck pressurises, toss the cauliflower florets in olive oil and a pinch of salt and spread on a baking sheet. Roast at 200°C (180°C fan) for 18–20 minutes until the edges are golden and the flesh is cooked through but not soft. This step can be skipped if you don’t have oven space, but raw cauliflower in the custard will be blander and slightly wetter.
5. Line and blind-bake the pastry. Press the shortcrust pastry into the springform pan, trimming the excess level with the top edge. Prick the base all over with a fork. Line with parchment, fill with baking weights or dried beans, and bake at 190°C for 12 minutes. Remove the weights and bake for a further 5 minutes until the base looks dry and just beginning to colour. This partial bake prevents the custard from making the base soggy.
6. Make the custard. Whisk the eggs, cream, salt, white pepper, and nutmeg together until smooth and uniform — about 45 seconds of steady whisking. Add the thyme leaves and two-thirds of the Gruyère and whisk briefly to combine. The custard should be pale yellow, slightly frothy on the surface, and smell faintly of nutmeg.
7. Assemble the quiche. Scatter the shredded duck over the pastry base in an even layer. Tuck the cauliflower florets among the duck pieces. Pour the custard slowly and evenly over the filling — go slowly at the edge where it might pool and overflow. Scatter the remaining Gruyère across the surface. Cover the pan loosely with a circle of foil, crimping it lightly at the edges but leaving room for the custard to expand slightly as it cooks.
8. Pressure-cook the quiche. Clean and dry the Instant Pot insert. Pour in 240ml water and place the trivet inside. Lower the springform pan onto the trivet using a foil sling — two long strips of foil folded to ribbons, crossed beneath the pan, with the ends extending up the sides for grip. Seal the lid, set to Sealing, and pressure cook on Low for 25 minutes. Use Low pressure, not High — High pressure will cause the custard to puff and crack rather than set cleanly. Natural release for 10 minutes, then quick release.
9. Check the set and cool. Lift the pan from the pot using the foil sling. The surface of the quiche should be set and pale gold, with a slight tremble at the very centre when you nudge the pan — like a set jelly that hasn’t fully firmed. Do not cut it now. Allow it to cool at room temperature for at least 20 minutes; the custard firms as it cools and the quiche will hold its shape when sliced. Cutting too early produces a spill, not a slice.

The Quiet Decisions

The braising liquid from the duck is worth a moment of attention before you discard it. Two tablespoons stirred into the custard in place of the same amount of cream add a depth of flavour — a dark, meaty undertow beneath the egg richness — that the dish doesn’t announce but would miss if it were gone. Do not add more than two tablespoons; the liquid is concentrated and salty.

The foil cover over the pan during pressure cooking is not optional. Without it, condensation from the steam drips directly onto the custard surface and produces a wet, grey-looking top that has neither colour nor texture. The foil deflects the drips and allows the surface to set with some integrity.

Let the shortcrust pastry come to room temperature before pressing it into the pan. Cold pastry cracks at the corners where it needs to bend. A 10-minute rest on the counter prevents the hairline splits that become full tears when the custard bears down.

What to Watch For

The custard doesn’t set. Almost always a pressure issue — the pot was set to High instead of Low, or the natural release was shortened and the custard didn’t finish cooking in the residual heat. If you open the pot and the centre is still visibly liquid, reseal and cook on Low for a further 8 minutes with a 5-minute natural release. A slightly underset quiche can also be recovered by placing the pan uncovered in a 160°C oven for 10–12 minutes.

The base is wet. The blind-bake was skipped or cut short. There is no remedy once the quiche is assembled; the pastry will remain soft. Next time, blind-bake fully until the base is dry to the touch before adding any filling.

The duck is stringy and dry. The legs were not browned long enough before braising, or the natural release was skipped and the pressure was released too quickly — rapid pressure release causes muscle fibres to seize. The 15-minute natural release is the period during which the proteins relax and the meat becomes genuinely tender rather than merely cooked.

The custard surface is waterlogged and grey. The foil cover was sealed too tightly, trapping steam against the surface rather than deflecting it. Crimp the foil loosely — it should rest over the pan, not clamp to it.

Variations That Hold Up

Swap the duck for confit chicken thighs. Bone-in chicken thighs pressure-cooked on High for 15 minutes produce a similarly shreddable, gelatinous result with a lighter flavour profile. The custard can stay identical; the dish reads as more approachable without losing the richness that makes the quiche interesting.

Add roasted mushrooms to the filling. Cremini or shiitake mushrooms, roasted until dark and concentrated, add an earthy layer between the duck and the cauliflower that deepens the overall flavour without adding bulk. Use 100g, roasted alongside the cauliflower on a separate area of the baking sheet.

Replace Gruyère with aged Comté. Comté has a more pronounced nuttiness and a slightly fruity finish that suits the duck particularly well. The melt is similar; the flavour is more complex. This is an upgrade, not a substitution.

Introduce a herb layer. A tablespoon of finely chopped fresh tarragon stirred into the custard alongside the thyme shifts the flavour toward French bistro territory. Tarragon and duck have an old alliance — the anise note in the herb cuts through the fat in a way that thyme alone does not.

How to Serve It

Instant Pot duck and cauliflower quiche is best served warm, not hot — allow 20 minutes of resting time after cooking before slicing, and another 10 if you want clean wedges rather than soft ones. At warm room temperature, the custard is at its most yielding and the duck flavour is fully forward.

A simple undressed green salad — watercress, frisée, or a mix of bitter leaves — alongside a sharp mustardy vinaigrette provides the acidity the quiche lacks and keeps the plate from reading as too rich. Avoid anything creamy on the side; the custard fills that role already.

For a more complete meal, add a small bowl of soup — a clear broth or a light vegetable purée works well. Avoid cream-based soups; doubling down on dairy alongside this quiche becomes heavy quickly.

The quiche serves 6 as part of a spread, 4 as a main course with salad and bread. It is also one of those dishes that reheats so well that leftovers the next day are not a consolation — they are a reasonable argument for making the full recipe even when cooking for two.

The Next Day

Refrigerate leftovers in the springform pan, covered with foil, or transfer to an airtight container. The quiche keeps for 3 days. By the second day, the pastry will have softened further and the flavours will have deepened and merged — the duck becomes less distinct, more integrated into the custard, which many people prefer.

To reheat: a 160°C oven for 12–15 minutes produces the best result, warming the filling through while the pastry firms slightly at the edges. The microwave works but softens the base completely and heats the egg unevenly — acceptable for a quick lunch, less so for a meal you took care to make properly. Do not reheat from frozen; the custard weeps and the pastry turns to mush as the ice crystals rupture the egg protein structure during thawing.

There is a particular satisfaction in a dish that compresses effort — where forty minutes of active work produces something that reads, on the plate, as a whole afternoon’s project. Instant Pot duck and cauliflower quiche is that dish: the pressure cooker does the slow work invisibly, and what emerges has the weight and depth of something braised and tended over hours.

Make it once and you will understand the Instant Pot not as a shortcut, but as a different kind of patience — one that happens without you.
