Prep the bread and preheat — Preheat your oven to 425°F (220°C) or preheat a skillet over medium-high heat. Arrange 8 baguette slices on a baking sheet and brush both sides very lightly with 1 tbsp olive oil. Toasting at high heat crisps the bread quickly to create a sturdy base that won’t get soggy under the mash; the small amount of oil helps develop an even golden crust and flavor.

Warm the spices to bloom their flavor — In a small dry skillet over low heat toast 1/2 tsp smoked paprika and 1/2 tsp ground cumin for 15–20 seconds, just until aromatic. Warming spices briefly releases their essential oils and deepens aroma; be careful not to burn them, which makes them bitter.

Make the chickpea mash — In a medium bowl, add the drained chickpeas, 1 tbsp olive oil, 2 tbsp lemon juice, 2 tbsp plain Greek yogurt, 2 minced garlic cloves, the toasted paprika and cumin, 3/4 tsp salt, and 1/2 tsp black pepper. Using a fork or potato masher, coarsely mash the mixture until mostly smooth but with small whole chickpeas for texture. Leaving some whole beans gives the mash a rustic mouthfeel and prevents it from becoming gluey — overblending (as in a food processor) can produce a gummy texture.

Fold in the finishing touches — Stir in 1/4 cup crumbled feta and 2 tbsp chopped parsley, reserving a little feta and parsley for garnish. The feta adds a salty, creamy pop that complements the lemon; folding it in at the end prevents it from dissolving completely so you get little bursts of flavor.

Toast the baguette — Transfer the prepared baguette slices to the oven and toast 6–8 minutes (or 1–2 minutes per side in the skillet) until deeply golden and crisp. For extra flavor, rub one side of each hot toast with a cut clove of garlic — the friction imparts gentle garlic aroma without overpowering the mash. Hot toast ensures contrast with the cool mash and helps the flavors sing.

Assemble the crostini — Spoon about 2–3 tablespoons of chickpea mash onto each toasted baguette slice, pressing slightly so it adheres. Sprinkle with the reserved feta and parsley and a light pinch of smoked paprika or red pepper flakes if desired. Serve immediately so the toast remains crisp; assembling too far ahead will soften the bread.

Optional garnish and serve — If using, scatter 2 tbsp toasted pine nuts over the crostini for a buttery crunch or finish with a drizzle of extra-virgin olive oil for gloss and aroma. Serve warm or at room temperature as a quick snack or appetizer.
