Pissaladière: A Savory Anchovy, Onion and Olive Tart

Pissaladière is a savory tart from Nice in southern France, traditionally made with bread-like dough, slow-cooked onions, anchovies, and olives. Its soft, sweet onion layer balances the salty, savory toppings, making it satisfying warm from the oven or at room temperature.

Ingredients

2 1/2 cups (315 g) all-purpose flour, plus a little extra for shaping
3/4 cup (180 ml) warm water, about 100–110°F (38–43°C)
1 teaspoon (3 g) instant yeast
1 teaspoon (5 g) fine salt, for the dough
2 tablespoons (30 ml) extra-virgin olive oil, for the dough
2 pounds (900 g) yellow onions, peeled and thinly sliced
3 tablespoons (45 ml) extra-virgin olive oil, for the onions
1/2 teaspoon (2.5 g) fine salt, for the onions, plus more only if needed
1 bay leaf
1 teaspoon dried thyme (about 1 g), or 1 tablespoon (3 g) fresh thyme leaves
1/4 teaspoon freshly ground black pepper (about 0.5 g)
12 oil-packed or salt-packed anchovy fillets (about 30 g), drained; rinse salt-packed fillets briefly and pat dry
1/2 cup (70 g) small black olives, preferably Niçoise-style, pitted if desired
1 teaspoon (5 ml) olive oil, for greasing the pan

Instructions

Make and proof the dough. In a large bowl, stir together the flour, yeast, and dough salt. Add the warm water and 2 tablespoons (30 ml) olive oil, then mix until a rough dough forms. Knead on a lightly floured counter for about 8 minutes, until smooth and elastic; add flour a teaspoon at a time only if it is very sticky. Put the dough in a lightly oiled bowl, cover, and let it rise in a warm, draft-free place for 60 minutes. It should look puffy and expand noticeably, though it does not need to double exactly.
Cook the onions slowly. While the dough rises, heat 3 tablespoons (45 ml) olive oil in a wide, heavy skillet over medium-low heat. Add the sliced onions and 1/2 teaspoon salt, and stir to coat. Cook for 45 minutes, stirring every few minutes and lowering the heat if the edges begin to brown. The onions should become very soft, glossy, and pale golden, not crisp or deeply caramelized. Stir in the bay leaf, thyme, and black pepper for the final 2 minutes, then remove the pan from the heat and discard the bay leaf. Taste before adding any more salt; anchovies and olives will season the tart later.
Shape the base and add the topping. Brush a rimmed 9-by-13-inch (23-by-33-cm) baking pan with the teaspoon of oil. Press or roll the risen dough into a rectangle that fits the pan, easing it into the corners without stretching it thin. If it springs back, cover it and let it relax for 5 minutes before continuing; that short pause is part of shaping, not an extra proof. Spread the onion mixture evenly over the dough, leaving a narrow border. Arrange the anchovy fillets in a loose lattice or evenly spaced lines, then scatter the olives across the top. Press them lightly into the onions so they stay put when sliced.
Preheat the oven. Set a rack in the center and heat the oven to 425°F (220°C). Let the assembled tart stand while the oven heats, about 15 minutes. This brief rest also gives the dough a chance to relax after shaping, but it should not be left uncovered in a draft.
Bake until the crust is done. Bake for 25 minutes, until the edges are golden and the bottom is firm when carefully lifted with a spatula. The onions should be hot and the anchovies should look softened and fully heated. Anchovies are fish; USDA FSIS lists 145°F (63°C) as the safe minimum internal temperature for fish, so check a thick area of the topping with a food thermometer if you need to verify it. If the crust is browning too quickly, loosely cover the edges with foil for the final minutes.
Rest, then portion. Set the pan on a rack for 10 minutes so the crust firms and the onions settle. Cut into 8 squares or rectangles with a sharp knife. Serve warm or let the tart cool further to room temperature; avoid trying to lift out the first piece while the topping is piping hot, as the soft onions can slide.

Tips

Keep the onion heat gentle. Pissaladière depends on tender, mellow onions rather than crisp or darkly browned ones. If they start sticking before they soften, turn down the burner and add a tablespoon of water; scrape up the flavorful bits instead of increasing the heat.
Choose anchovies to suit your salt preference. Oil-packed fillets are ready to use after draining. Salt-packed anchovies have a firmer, more intense flavor, so rinse them briefly, remove any obvious bones, and pat them dry. If you are sensitive to salt, use 8 fillets and leave the onion mixture lightly seasoned.
Use a practical olive substitute. Niçoise olives can be hard to find. Small Kalamata or other brined black olives work well, though they are often larger and fruitier; pit them and use about 1/2 cup (70 g) chopped or halved olives so their flavor does not overwhelm each slice.
Do not overload the dough. Spread the onion layer evenly rather than piling it in the center. A very thick topping can make the middle soggy and prevent the base from baking through. If your onions release a pool of liquid, drain off the excess before spreading them.

Serving Suggestions

Serve pissaladière as a light main course with a crisp green salad dressed with vinaigrette. The tart is rich and savory, so simple sides work best: sliced tomatoes, steamed green beans, or a bowl of vegetable soup are all good companions. For a larger meal, offer it alongside roasted vegetables or a platter of raw vegetables and a tangy dressing.

For an appetizer or buffet, cut the tart into narrow strips or small squares once it has rested. It travels well for a picnic or potluck because it is enjoyable at room temperature, and it is easier to portion after the onions have settled. Put out lemon wedges if you like a brighter contrast, but taste a bite first: the anchovies and olives already provide plenty of savory intensity.

Variations

There are regional and household variations of pissaladière, including differences in the dough, the amount of anchovy, and the type or arrangement of olives. This version uses a simple yeast dough, close to a bread base. For a quicker, crisper tart, use prepared pizza dough; the flavor and texture will be similar, though the crust may be chewier. Puff pastry is another convenient option, but it produces a flaky, buttery base rather than the traditional bread-like one. Follow the pastry package directions for baking time and watch the edges carefully.

To make the topping less intense, arrange fewer anchovies in a widely spaced pattern and let each person add more at the table. For a stronger anchovy flavor, mash two fillets into the onions near the end of cooking, then arrange the remaining fillets on top. You can add a tablespoon of capers (about 8 g) with the olives for a sharper, brinier note; reduce added salt if you do. A little fresh thyme scattered over the tart after baking adds a more pronounced herbal aroma.

If you need a fish-free version, omit the anchovies and add a few extra olives and capers. It will still be a tasty onion tart, but it will lack the deep, salty savoriness that anchovies traditionally bring. For a milder topping, use fewer olives and choose a less salty variety rather than adding extra ingredients to replace the anchovies.

Storage and Reheating

Refrigerate leftover tart within 2 hours of baking. Cover the pan or transfer portions to an airtight container; the tart keeps for 3–4 days in the refrigerator. The crust softens somewhat as it sits, but reheating in the oven helps restore some crispness. Freeze cooled portions, well wrapped, for up to 2 months for best quality. Thaw overnight in the refrigerator before reheating; the onions may be softer after freezing.

To reheat a few slices, place them on a baking sheet in a 350°F (175°C) oven for about 8–12 minutes, until hot throughout and the base feels crisp. For a larger portion, allow extra time and cover loosely with foil if the topping is browning before the center is hot. Leftovers should reach 165°F (74°C) when reheated, as measured with a food thermometer. A microwave works in a pinch, but it makes the crust softer; use short bursts and check that the center is hot.

Frequently Asked Questions

What does pissaladière taste like?

It is savory and gently sweet, with soft onions as the main flavor and salty anchovies and olives providing contrast. The dough is more like a thin, tender bread crust than a buttery pie pastry. The exact balance varies with the olives and anchovies you choose, so taste the onion mixture before assembling and keep it lightly salted.

Can I make pissaladière ahead?

Yes. Cook the onions up to 2 days ahead, cool them promptly, and refrigerate them in a covered container. You can also make the dough the day before and refrigerate it after kneading; bring it toward room temperature before shaping, allowing extra time if it is still cold and firm. For the best crust, assemble and bake the tart on the day you plan to serve it.

Why is my tart base soggy?

The most common causes are watery onions, a very thick topping, or dough that is too thin in the center. Cook the onions until tender but not swimming in liquid, pour off any excess, and spread them in an even layer. Make sure the oven is fully heated and bake until the base is firm and lightly browned underneath.

Can I use store-bought pizza dough?

Yes. Use about 1 pound (450 g) of prepared pizza dough in place of the homemade dough, and follow the package instructions if its recommended oven temperature differs. Let refrigerated dough sit at room temperature for about 30 minutes so it is easier to stretch. The finished tart may have a slightly chewier crust, but the onion, anchovy, and olive topping remains the same.

Do I have to pit the olives?

No, but pitted olives are more convenient and safer to bite into, especially when serving small pieces at a gathering. If you use olives with pits, tell guests clearly and consider removing the pits before arranging them. Whole small olives make a traditional-looking topping; halved or chopped olives are easier to distribute evenly.

Can I serve it cold?

It is best warm or at room temperature, when the onions are soft and the crust still has some texture. Chilled leftovers are safe to eat if they have been refrigerated properly, but the olive oil may firm up and the dough will taste denser. Let a portion stand briefly at room temperature or reheat it in the oven for a better texture.
