Hazelnut Free Pesto-Walnut Artichoke Olive Crostini

These crispy whole-grain crostini are the kind of appetizer that disappears from the platter before you've even finished arranging them. Each bite layers a bright, garlicky walnut pesto with a tangy artichoke and Castelvetrano olive topping — briny, herby, and just a little addictive. Walnuts stand in as the pesto base here, delivering that rich, nutty depth without any hazelnut in sight, which makes this a genuinely safe and satisfying option for anyone navigating tree nut sensitivities around that specific ingredient. The pesto comes together in a food processor in under a minute, and the artichoke-olive mixture is just a quick toss with lemon juice and olive oil — no cooking required beyond toasting the bread. A pinch of red pepper flakes and a scatter of fresh basil at the end push the whole thing from simple to stunning. Whether you're building a party spread or just want something impressive for a weeknight snack, this one punches well above its effort level.
