European Ham Recipes: French Ham and Leek Quiche

This French-inspired ham, leek, and Gruyère quiche pairs savory cooked ham and soft leeks with a creamy egg filling in a crisp, buttery pastry shell. It is a practical European-style meal for brunch or supper, and the ham makes the filling hearty without requiring a long-cooked joint; versions vary, so this is a home-style variation rather than a claim to be a single traditional formula.

Ingredients

1 1/4 cups (160 g) all-purpose flour, plus a little more for rolling
1/2 cup (113 g) cold unsalted butter, cut into small cubes
1/4 teaspoon (1.5 g) fine salt, for the pastry
3 tablespoons (45 ml) ice water, plus up to 1 tablespoon (15 ml) more if needed
1 tablespoon (14 g) unsalted butter, for cooking the leek
2 cups (about 200 g) thinly sliced, cleaned leek, white and pale green parts
1 1/2 cups (225 g) diced fully cooked ham
1 cup (100 g) grated Gruyère cheese
4 large eggs (about 200 g without shells)
1 cup (240 ml) heavy cream
1/2 cup (120 ml) whole milk
1 teaspoon (5 ml) Dijon mustard
1/4 teaspoon (0.5 g) ground black pepper
1/8 teaspoon (about 0.25 g) freshly grated nutmeg
1 tablespoon (8 g) finely chopped fresh chives, optional

Instructions

Make the pastry. Put the flour and pastry salt in a mixing bowl. Add the cold butter and rub it into the flour with your fingertips, or pulse briefly in a food processor, until the mixture has uneven crumbs about the size of peas. Drizzle in 3 tablespoons (45 ml) ice water and mix just until the dough begins to hold together when pressed. Add the extra tablespoon only if it still looks dry and crumbly. Shape into a flat disk, wrap, and refrigerate for 30 minutes. Avoid kneading; working the dough too much can make the crust tough.
Roll and blind-bake the shell. While the dough chills, heat the oven to 375°F (190°C). Lightly flour the work surface and roll the dough into a circle about 12 inches (30 cm) wide and roughly 1/8 inch (3 mm) thick. Fit it into a 9-inch (23 cm) pie plate, leaving a little overhang; fold the edge under and crimp it. Prick the base several times with a fork, line it with parchment, and fill with pie weights or dry beans. Bake for 15 minutes, then carefully lift out the parchment and weights. The shell should look set but not deeply browned. Set it aside while you prepare the filling.
Soften the leek. Melt 1 tablespoon (14 g) butter in a skillet over medium heat. Add the sliced leek and cook for about 8 minutes, stirring regularly, until tender but not browned. If the pan seems dry or the leek starts to catch, lower the heat and add a teaspoon of water. Spread the cooked leek on a plate for a few minutes so excess steam can escape; this helps keep the quiche filling from turning watery.
Mix the custard and assemble. In a bowl, whisk the eggs, cream, milk, Dijon mustard, black pepper, and nutmeg until evenly combined. Scatter the leek, diced ham, and grated Gruyère over the pastry shell. Pour the egg mixture over the filling slowly, stopping just below the top of the crust. If the shell is shallow, hold back a little custard rather than risk spilling it while moving the quiche. Sprinkle chives over the top if using.
Bake until set. Place the pie plate on a baking sheet and bake at 375°F (190°C) for about 38 minutes. The edges should be puffed and lightly golden; the middle may still have a slight wobble but should not look liquid. Check the center with a food thermometer: egg dishes should reach the USDA FSIS safe minimum internal temperature of 160°F (71°C). If the crust browns too quickly, loosely cover its edge with foil for the last part of baking.
Rest before slicing. Set the quiche on a rack and let it stand for 15 minutes. This cooling time helps the custard finish setting, so the slices hold together instead of running across the plate. Cut into six wedges and serve warm or at room temperature.

Tips

Clean leeks carefully. Soil often collects between the layers. Slice the leek first, swish the pieces in a bowl of cold water, then lift them out and drain well. Do not pour the bowl through a strainer that lets the grit fall back onto the leek.
Choose the ham to suit the salt level. Leftover roast ham, smoked cooked ham, or a mild European-style cooked ham all work. If using a salty cured ham, taste a small piece before adding it and skip extra salt in the custard; the cheese contributes salt too. Prosciutto or another dry-cured ham is a possible substitute, but it gives a more concentrated, saltier flavor and a less meaty texture.
Keep the pastry cold and handle it lightly. If the dough gets soft or sticky as you roll it, return it to the refrigerator for 10 minutes. A crack can be patched with a small scrap of dough pressed into place. Do not stretch the dough to fit the pie plate, because it may shrink during baking.
Prevent a soggy or overfilled quiche. Cook off moisture from the leek, blind-bake the shell, and pour in only as much custard as the crust can hold. If your pie plate is especially shallow, bake any extra custard in a greased ramekin alongside the quiche and check it for doneness separately.

Serving Suggestions

Serve a warm wedge with a crisp green salad dressed with a simple vinaigrette. The acidity of mustard, cider vinegar, or lemon in the dressing balances the cream and cheese; keep the salad lightly dressed so it does not overwhelm the pastry. For a more substantial lunch or supper, add boiled new potatoes, roasted carrots, or steamed green beans. A few cornichons or a small spoonful of whole-grain mustard alongside the slice also complement the ham.

For brunch, offer the quiche with sliced tomatoes, fruit, and bread, and let it rest until just warm before cutting. It can also be served at room temperature for a buffet, provided it is not left out for more than two hours. Cut smaller wedges when serving several dishes, since the filling is rich and satisfying. Chives add a fresh finish, but a little chopped parsley can be used instead.

Variations

Use Comté or Emmental: Replace Gruyère with the same quantity of Comté for a similarly nutty flavor, or use Emmental for a milder, sweeter result. Cheddar is an accessible alternative, though it makes the quiche taste less French-inspired. Grate cheese from a block when possible so it melts smoothly.

Make it with a prepared crust: A 9-inch (23 cm) unbaked pie shell can replace the homemade pastry. Follow the package directions for blind-baking, since shell sizes and baking instructions vary. This saves time, but the crust may be less buttery; check its browning before filling and cover the rim if needed.

Add mushrooms: Cook 1 cup (100 g) sliced mushrooms in the skillet before adding the leek, letting their released liquid evaporate. This adds an earthy flavor, but do not add raw mushrooms directly to the custard, as their moisture can make the center watery.

Try a spinach version: Substitute 2 cups (60 g) baby spinach for the leek, wilt it in the skillet, and squeeze or cook away excess water before adding it. The result is greener and lighter in flavor. For a milder allium note, use 1 cup (100 g) thinly sliced onion instead of leek and cook until soft and translucent.

Storage and Reheating

Let the quiche cool, then refrigerate it within 2 hours of baking. Cover the pie plate tightly or transfer slices to a covered container; keep it refrigerated for 3 to 4 days. Do not leave it at room temperature overnight, even if the filling seems firm. For easier packed lunches, cut the cooled quiche into portions before storing.

To reheat a slice, place it on a baking sheet and warm it in a 325°F (165°C) oven for about 12 to 18 minutes, until hot throughout. A whole refrigerated quiche can take 20 to 30 minutes at the same temperature, depending on its depth. Check reheated leftovers with a food thermometer and bring them to 165°F (74°C), the USDA FSIS reheating temperature. A microwave works for a quick portion, but use short bursts and expect a softer crust.

For longer storage, freeze individually wrapped slices in a freezer-safe container for up to 2 months for best quality. Thaw overnight in the refrigerator and reheat as above; the custard may be a little less silky after freezing. Freezing the whole quiche is possible, but slices are easier to thaw evenly and serve without repeatedly warming the entire pie.

Frequently Asked Questions

What kind of ham works best in this quiche?
Use fully cooked ham with a flavor you enjoy, such as leftover roast ham, smoked ham, or cooked European-style ham. Dice it into small, even pieces so each slice gets some ham. Very salty or strongly cured ham can dominate the cream and cheese, so use a smaller amount or pair it with a mild cheese if needed.

Can I make the quiche ahead?
Yes. Bake it fully, cool it, and refrigerate it within 2 hours. It keeps for 3 to 4 days refrigerated and can be served cold, at room temperature for a short serving period, or reheated. You can also make the pastry disk a day ahead and keep it wrapped in the refrigerator; if it is very firm, let it stand briefly until it is rollable.

Why is the middle still soft when the edges look done?
A slight wobble is normal, but the center should not slosh or look like liquid custard. Oven temperatures and pie-plate materials vary, so begin checking near the end of the stated bake time and use a thermometer to confirm 160°F (71°C) at the center. If the crust is already brown, loosely shield it with foil while the filling finishes.

Can I use milk instead of cream?
You can replace the cream with an equal amount of whole milk, but the filling will be less rich and may set more softly. Avoid using a very low-fat milk if you want neat slices. Keep the total liquid close to the amount in the recipe, and still check that the egg mixture reaches 160°F (71°C).

Is this the same as quiche Lorraine?
No. Quiche Lorraine is commonly associated with a custard and lardons or bacon, and many versions do not include cheese, though recipes differ. This recipe is a ham-and-leek variation with Gruyère, inspired by the broader French tradition of savory custard tarts rather than presented as a definitive regional original.

Can I make it without a homemade crust?
Yes. A store-bought 9-inch (23 cm) crust is a convenient substitute. Blind-bake it according to its package directions before adding the filling if it is sold unbaked; a ready-to-use baked shell can be filled directly, though it may brown more during the final bake. Watch the edges and cover them if they darken too quickly.
