I wanted a quiche that felt special but didn’t demand a full morning in the kitchen — and this bacon and prosciutto quiche with a crushed potato chip topping is exactly that. It comes together in under 30 minutes, uses a store-bought pie crust (no shame), and has a flavour combination that genuinely surprises people.
The trick is layering salty, crispy textures on top of a simple egg and cream filling:
- Smoky bacon pieces folded right into the custard
- Torn prosciutto draped across the surface so it crisps in the oven
- Crushed salted potato chips sprinkled over everything for an addictive crunch
The potato chip topping sounds unusual, but it works beautifully — think of it as a shortcut gratin crust that adds salt, fat, and texture in one handful. The custard stays creamy inside while the top turns golden and crispy.
This is the quiche I make when friends are coming for brunch and I want something that looks impressive but takes almost no effort.
Easy Bacon & Prosciutto Quiche with Potato Chip Crust Topping
Ingredients
- 3 large eggs
- ½ cup heavy cream or cooking cream
- ½ cup shredded Gruyère or cheddar cheese
- 4 oz bacon cut into small cubes
- 2 slices Jamón Serrano or prosciutto about 1 oz total
- 1 cup crushed salted potato chips salted
- 1 medium refrigerated pie crust 9-inch (23cm)
Instructions
- Preheat the oven to 400°F / 200°C (180°C fan-forced).
- Heat a small skillet over medium heat. Cook the bacon cubes, stirring occasionally, for 5–6 minutes until golden and crispy. Transfer to a paper towel-lined plate to drain.
- Unroll the refrigerated pie crust and press it into a 9-inch (23cm) pie dish. Prick the base all over with a fork — this prevents the crust from puffing up during baking.
- While the bacon cooks, crack the eggs into a medium bowl and whisk vigorously until fully combined and slightly frothy, about 30 seconds.
- Pour in the cream and whisk until the mixture is smooth and uniform.
- Add the cooked bacon and shredded cheese to the egg mixture. Stir with a spoon until evenly distributed.
- Tear the Jamón Serrano or prosciutto into rough strips and arrange them across the top of the quiche.
- Scatter the crushed potato chips evenly over the entire surface of the quiche.
- Bake for 20–25 minutes until the filling is set and the top is golden brown — the centre should be firm with just a slight wobble. Remove from the oven and let cool on a rack for 5 minutes before slicing.

What Makes This Bacon and Prosciutto Quiche Special
Most quiche recipes follow the same formula — eggs, cream, cheese, bake. This one breaks the pattern with two moves that make all the difference.
First, the double-pork approach. Smoky bacon cubes are cooked until crispy and folded directly into the custard, so every bite has a hit of rendered, salty pork. Then torn strips of Jamón Serrano or prosciutto are laid across the top where they crisp up in the oven’s dry heat, adding a second layer of cured-meat flavour with a completely different texture.
Second, the potato chip topping. It sounds unconventional, but crushed salted potato chips scattered over the quiche before baking create a golden, crunchy crust that mimics a gratin topping without any of the work. The chips absorb just enough moisture from the custard to stay on top while keeping their crunch — it’s genuinely addictive.
The result is a quiche that takes under 35 minutes from start to finish but tastes like you spent the morning on it.
Equipment You’ll Need
- 9-inch pie dish — the standard size that fits a store-bought pie crust perfectly. Glass or ceramic lets you check if the bottom crust is browning.
- Small skillet or frying pan — for rendering the bacon cubes until crispy. A non-stick pan makes cleanup easier since bacon releases a lot of fat.
- Medium mixing bowl — for whisking the egg and cream custard and combining it with the bacon and cheese.
- Whisk — essential for incorporating air into the eggs and creating a smooth, lump-free custard. A fork will work in a pinch but produces a denser filling.
- Fork — for docking (pricking) the pie crust base to prevent it from bubbling up during baking.
- Cooling rack — letting the quiche cool slightly on a rack rather than directly on the countertop prevents the bottom crust from steaming and going soggy.
Tips for Best Results
- Drain your bacon well. Excess grease in the custard will make the filling oily and can prevent it from setting properly. Let the cooked bacon sit on a paper towel for a minute before adding it to the egg mixture.
- Don’t skip docking the crust. Those fork holes in the base allow steam to escape so the pastry stays flat. Without them, you’ll get large air pockets that push the filling to one side.
- Crush the chips to a coarse texture, not a powder. You want pieces roughly the size of a fingernail — small enough to create even coverage but large enough to maintain crunch after baking.
- Check for doneness at 20 minutes. The quiche is ready when the edges are set and the very centre has a gentle wobble — it will continue to firm up as it cools. If the centre is still liquid, give it another 3–5 minutes.
- Let it rest before cutting. Five minutes of resting allows the custard to finish setting. Cut too early and the filling will run out across the plate.
Substitutions and Variations
- Bacon alternatives: Pancetta cubes, cooked chorizo crumbles, or smoked turkey bacon all work. Adjust cooking time since pancetta renders faster than standard bacon.
- Cheese swaps: Gruyère is the classic quiche cheese and melts beautifully. Smoked Gouda, Comté, or sharp cheddar are all excellent choices. Avoid pre-shredded bags with anti-caking agents — they don’t melt as smoothly.
- Cream options: Heavy cream gives the richest custard. Half-and-half works for a slightly lighter version. Avoid milk — the custard won’t set as firmly.
- Vegetable additions: Sautéed spinach (squeezed dry), roasted red peppers, or caramelised onions can be folded into the custard. Keep additions to about ½ cup total so the custard ratio stays balanced.
- Skip the chips: If the potato chip topping isn’t your thing, substitute breadcrumbs tossed with a little melted butter, or simply leave the top plain with just the prosciutto.
Storage and Reheating
- Refrigerator: Cover the cooled quiche tightly with plastic wrap or transfer slices to an airtight container. Keeps well for up to 3 days.
- Freezer: Wrap individual slices in aluminium foil, then place them in a freezer-safe bag. Frozen quiche keeps for up to 2 months. Thaw overnight in the refrigerator before reheating.
- Reheating: For the best texture, reheat slices in a 325°F / 165°C oven for 10–12 minutes until warmed through. The oven restores the crispness of the potato chip topping and the crust. Microwaving works in a pinch but will soften the topping completely.
What to Serve With This
- Simple green salad — dressed with a sharp Dijon vinaigrette to cut through the richness of the custard and bacon.
- Roasted cherry tomatoes — their acidity and sweetness balance the salty, smoky flavours of the quiche perfectly.
- Fresh fruit — a bowl of berries or sliced melon keeps the brunch spread light alongside this rich dish.
- Crusty baguette — because quiche and bread is a French combination that never fails.
- Mimosas or fresh orange juice — the citrus brightness pairs naturally with egg-based brunch dishes.
Frequently Asked Questions
Can I make this quiche without a store-bought crust?
Absolutely. A basic homemade shortcrust pastry works perfectly — you’ll need about 9 oz (250g) of dough rolled to ⅛-inch thickness. Blind-bake it with pie weights at 400°F / 200°C for 8 minutes before adding the filling so the base stays crisp.
Why did my quiche come out watery?
The most common cause is underbaking. The custard needs to be fully set at the edges with only a very slight wobble in the centre. Excess liquid from the bacon (not draining it enough) or adding wet vegetables without squeezing them dry can also introduce too much moisture.
Can I use a different type of chip for the topping?
Yes — any salted, unflavoured potato chip or crisp will work. Kettle-cooked chips hold up especially well because they’re thicker and crunchier. Flavoured varieties like salt and vinegar or barbecue can be fun but will change the flavour profile significantly.
Do I need to blind-bake the pie crust first?
The original recipe skips blind-baking, and it works because the filling is relatively small and the oven temperature is high. However, if you find the bottom crust is soggy, blind-bake it for 5 minutes at 400°F / 200°C before adding the filling — this creates a moisture barrier.
Can I make this quiche ahead for a brunch party?
Yes. Bake the quiche the evening before, let it cool completely, cover with plastic wrap, and refrigerate. Reheat the whole quiche in a 325°F / 165°C oven for 15–20 minutes before serving. The chip topping will soften slightly overnight but will re-crisp somewhat during reheating.
Is this really a traditional French quiche?
It’s French-inspired rather than strictly traditional. A classic Quiche Lorraine uses a shortcrust pastry, eggs, cream, and lardons (French-style bacon). This version riffs on those core elements but adds prosciutto and the playful potato chip topping — think of it as a modern, shortcut take on the French original.
The Story Behind Quiche
Quiche originated in the Lorraine region of northeastern France, near the German border, as far back as the 16th century. The word itself comes from the German Kuchen, meaning cake. The original Quiche Lorraine was an open custard tart filled with eggs, cream, and smoked bacon — no cheese, despite what most modern recipes suggest. Cheese was added later and technically makes it a Quiche Vosgienne. Over the centuries, quiche migrated from rural French farmhouse cooking to Parisian bistros and eventually to brunch tables worldwide. This version honours the spirit of the original — eggs, cream, and pork — while taking a distinctly modern shortcut with the chip topping that a traditional French cook might raise an eyebrow at but would probably enjoy.
