This quiche uses a store-bought pie crust, seven ingredients, and a bag of potato chips to produce something that looks like you put in real effort. The filling is a straightforward egg-and-cream custard with crispy bacon folded in, topped with torn prosciutto and crushed chips that bake into a crunchy, salty crust. It’s done in 35 minutes, and it works just as well for a weekend brunch as it does for a weeknight dinner with a salad on the side.
The technique that matters
The one thing worth paying attention to is the order of the topping. The torn prosciutto goes down first, directly on the custard, and the crushed chips go on top of that. If you reverse the order, the chips sink into the wet filling and turn soft before the quiche sets. Laid on top of the prosciutto, they stay elevated just enough to stay crispy. The second thing: don’t crush the chips to crumbs. Rough, uneven pieces — some the size of a thumbnail, some smaller — give you better texture than a uniform powder, and they look better too.
Ingredient notes
- Prosciutto vs. Jamón Serrano: Either works. Jamón Serrano is slightly less fatty and crisps up a little firmer. Prosciutto goes a bit more lacy and delicate. Both are good — use whichever is cheaper at your store.
- Potato chips: Plain salted chips are the right call here. Flavored varieties (sour cream, barbecue, salt and vinegar) will compete with the bacon and cheese in ways that don’t quite work. Kettle-style chips hold their texture a little better than thin chips.
- Cheese: Gruyère melts smoothly and has a mild nuttiness that works well with the pork. Cheddar is sharper and more familiar — skip the garnish and just use whichever your family will actually eat, because the difference in the final dish is small.
- Heavy cream: Half-and-half will work if that’s what you have, but the custard will be slightly less rich and may take a minute or two longer to set fully.
Leftovers and make-ahead
Leftover quiche keeps well in the fridge for up to 3 days, covered tightly. The chip topping softens overnight — it won’t be crunchy the next day, but the flavor is still good. To reheat, use the oven at 325°F for about 10 minutes rather than the microwave, which makes the crust rubbery. Individual slices can go in a toaster oven for 8 minutes if you want something faster. This quiche doesn’t freeze well — the custard weeps and the crust goes soggy on thawing, so it’s best made fresh. If you want to get ahead, cook and drain the bacon up to two days in advance and store it in the fridge in a sealed container; the rest comes together in minutes on the day.
Common problems and fixes
- Filling is still liquid in the center after 25 minutes: Ovens vary. Cover the edges loosely with foil to stop the crust burning, and give it another 5 minutes. The center should jiggle like set Jell-O, not slosh.
- Chips burned before the filling set: This usually means the oven runs hot or the chips were spread too thin at the edges. Next time, keep the chips away from the very outer edge of the quiche, and check at the 18-minute mark.
- Custard is watery after slicing: The quiche wasn’t rested long enough. Five minutes on a rack is the minimum — ten is better. Cutting too soon lets steam escape as liquid rather than finishing the set.
- Pie crust shrank or slid down the dish during baking: The crust wasn’t pressed firmly enough into the corners of the dish, or it wasn’t chilled before going in. Press it snugly, prick it well, and if your kitchen is warm, pop the unbaked shell in the fridge for 10 minutes before adding the filling.
- Prosciutto is chewy rather than crispy: It needs direct dry heat to crisp. If it’s buried under chips rather than sitting on top of the custard with chips over it, it steams instead of crisping. Lay it flat and make sure the chips cover it loosely, not in a thick pile.
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.

Frequently asked questions
Can I use bacon bits from a bag instead of cooking fresh bacon?
You can, but the texture will be softer and the flavor is noticeably less good. Real bacon cooked in a skillet renders out fat and gets genuinely crispy in a way that pre-cooked bacon bits don’t — and that crispiness matters inside a custard filling.
Can kids who don’t like strong flavors eat this?
Yes — the custard itself is mild, and cheddar keeps things familiar if you skip the Gruyère. The bacon and cheese flavors are present but not sharp, and the chip topping tends to be the part kids go for first.
Does the pie crust need to be pre-baked before adding the filling?
No — at 400°F the crust bakes through at the same time as the filling sets, so blind baking isn’t needed here. Docking the base with a fork (as the recipe instructs) is enough to prevent puffing.
