Asparagus has been a herald of spring in European and North American kitchens for centuries. It’s often served with hollandaise or vinaigrette, but in this version, we borrow from Japanese pantry staples to give it a modern, umami-rich twist. Kewpie mayo, beloved for its tang and silky texture, acts as the perfect backdrop for anchovies, lemon, garlic, and paprika. It’s a little luxe, a little unexpected, and incredibly satisfying.

This dish works as a weeknight vegetable side or a small-plate offering at a dinner party. It also plays well as part of a spring brunch spread or alongside grilled meats. What makes it special is the combination of roasted asparagus with a bold, creamy sauce and crunchy garlic breadcrumbs for contrast. It’s all about texture and balance—char meets cream meets crunch. If you’ve been leaning on butter and lemon for your asparagus, this is your cue to switch it up.

The mayo can be made ahead and kept in the fridge, so all you have to do is roast and plate. It’s easily doubled and scales beautifully for entertaining. This roasted asparagus recipe with anchovy Kewpie mayo is ideal for spring meals and highlights Japanese-inspired flavors with a Western technique.

Main Ingredients

Asparagus – Crisp-tender when roasted, asparagus brings a grassy, slightly sweet flavor that pairs well with umami-rich sauces. Look for medium-sized stalks that are uniform in thickness for even cooking. Local spring asparagus will always have the best texture and flavor.

Olive oil – Used to coat the asparagus for roasting, olive oil promotes caramelization and keeps the spears from drying out. A light drizzle is all you need. If you prefer, avocado oil or grapeseed oil can also work here.

Kewpie mayo – Richer and tangier than standard mayo, Kewpie adds creaminess and depth to the anchovy sauce. It emulsifies the lemon and anchovy beautifully. If unavailable, you can substitute regular mayonnaise and add a pinch of sugar and rice vinegar.

Anchovies – Anchovies bring that deep, salty umami that anchors the mayo sauce. They melt right in and enhance everything around them. Opt for oil-packed anchovy fillets of good quality, such as Ortiz or Agostino Recca.
