Steps
Before you start
- Zaalouk can be made up to 3 days ahead; its flavor improves overnight.
- Preserved lemons are sold in jars at Middle Eastern markets and many supermarkets. Rinse before using, as they are very salty.
- Line two rimmed baking sheets with parchment or foil for easy cleanup.
- Use a day-old, slim baguette (about 2 inches / 5 cm wide) so the slices are crisp and sturdy.
Preheat and prep eggplantOven 425°F / 220°C
- Position a rack in the center of the oven and heat to 425°F (220°C).
- Line a baking sheet with parchment.
- Score the cut side of each eggplant half in a crosshatch pattern, cutting ½ inch (1.25 cm) deep without piercing the skin.
- Brush the cut sides with 1 tablespoon of the roasting olive oil and sprinkle with a pinch of salt.
- Place cut side down on the sheet.

Ready when: Eggplant halves are oiled, scored and arranged cut side down.
Tip: Scoring helps the heat penetrate so the flesh turns silky rather than patchy.
Roast eggplantOven 425°F / 220°C
- Roast for 35 to 40 minutes, until the skins are wrinkled and slightly charred and the flesh collapses when pressed with a spoon.

Ready when: Skins are wrinkled and blistered, and a knife slides into the thickest part with no resistance.
Tip: Start the tomatoes while this roasts to use the time well.
Cool and chop eggplant
- Turn the halves over and let them cool for 15 to 20 minutes, until you can handle them.
- Scoop the flesh from the skins with a spoon, discarding the skins and any large clumps of seeds.
- Chop the flesh roughly with a knife, leaving some texture.
- Drain in a sieve for a few minutes if it looks watery.

Ready when: About 1½ cups (350 g) of soft, roughly chopped flesh.
Tip: Keep the oven on at 425°F (220°C) for toasting the bread later, or turn it off and reheat when ready.
Start the tomato base
- Heat 2 tablespoons olive oil in a 12-inch (30 cm) deep skillet over medium heat for 1 minute.
- Add the garlic, cumin, paprika and cayenne, if using.
- Stir for 30 seconds, until fragrant and sizzling but not browned.

Ready when: Garlic smells fragrant and spices darken slightly; no brown bits on the garlic.
Tip: If the garlic starts to brown, lift the pan off the heat right away; burnt garlic turns bitter.
Simmer tomatoes
- Add the diced tomatoes with their juices and ¼ teaspoon of the salt.
- Raise the heat to medium-high and bring to a bubble, then reduce to medium-low.
- Simmer, stirring occasionally, for 15 to 18 minutes, until the tomatoes break down into a thick, jammy sauce.

Ready when: A spoon dragged across the pan leaves a trail that stays open for a second or two.
Combine and reduce
- Stir the chopped eggplant, diced preserved lemon rind (reserving 1 teaspoon for garnish) and chopped cilantro into the tomatoes.
- Mash with a wooden spoon or potato masher to break up the eggplant.
- Cook over medium-low heat for 10 minutes, stirring often, until thick, spreadable and glossy.

Ready when: Mixture mounds on a spoon and no watery liquid pools around it.
Tip: A watery zaalouk will make the toasts soggy, so keep cooking until it holds its shape.
Season the spread
- Remove from the heat and stir in the lemon juice.
- Taste, and add more salt (start with ¼ teaspoon) if needed.
- Preserved lemon is salty, so season gradually.
- Let it cool to warm or room temperature.

Ready when: Tastes bright, smoky and well seasoned, with a gentle hum of cumin.
Toast the baguetteOven 400°F / 205°C
- Heat the oven to 400°F (200°C) if it was turned off.
- Arrange the baguette slices in a single layer on two baking sheets.
- Brush the tops lightly with the 3 tablespoons olive oil.
- Bake for 8 to 10 minutes, rotating the sheets and flipping the slices halfway, until golden at the edges and crisp.

Ready when: Slices are deep golden at the edges and feel dry and crisp when tapped.
Tip: Watch closely in the final 2 minutes; thin edges brown fast.
Cool the toasts
- Transfer the toasts to a wire rack or cutting board for 5 minutes.
- They crisp further as they cool.

Good to know
Tips
- Roast the eggplant until it is truly collapsed; undercooked eggplant stays spongy and tastes bitter.
- Add the preserved lemon gradually and taste before adding more salt, since brands vary widely.
- Cook the spread until thick. Wet topping is the main cause of soggy crostini.
- For a smokier flavor, char the eggplant over a gas flame or grill before roasting.
Make ahead
"Make the zaalouk up to 3 days ahead and refrigerate in an airtight container; serve cold, room temperature or gently warmed. Toast the baguette slices up to 1 day ahead and store airtight at room temperature. Assemble just before serving."
Storage & reheating
"Zaalouk: refrigerate in an airtight container up to 4 days; freeze up to 2 months and thaw overnight in the fridge. Rewarm in a skillet over low heat for a few minutes, or serve at room temperature. Toasts: keep airtight at room temperature up to 2 days; re-crisp at 350°F (175°C) for 3 minutes. Assembled crostini do not store well."
Substitutions
- preserved lemon → 1 teaspoon finely grated fresh lemon zest plus an extra ¼ teaspoon salt. Gives brightness but not the fermented depth of preserved lemon.
- slim baguette → Sliced ciabatta, pita triangles or gluten-free baguette. Toast until fully crisp; adjust time for thickness.
- fresh cilantro → Flat-leaf parsley. Milder, but still traditional in Moroccan cooking.
- ripe tomatoes → One 28-oz (800 g) can whole peeled tomatoes, drained and chopped. Best choice when fresh tomatoes are not in season; simmer a few extra minutes.
