Roasted Asparagus with Lemon Olive Oil Mayonnaise

My husband’s birthday coincides with the start of the asparagus season. When we first moved to California, his birthday dinner always included fresh asparagus. Years later, we still can’t wait to cook those first stalks, a true harbinger of spring.

Lemon olive oil, made by either crushing the citrus along with the olives or by infusing the oil, is a natural companion for asparagus. Many California producers use Meyer lemons, a special crop in the state, which are more floral and slightly sweeter that the standard Eurekas. Although I love lemon oil, it might be too much by itself, so I mix it with a delicate extra-virgin olive oil in these recipes.

The roasted asparagus will stand on its own, but if you want to elevate it to another level, serve it with the mayonnaise.

4 to 6 servings

For the mayonnaise:
2 extra-large egg yolks, at room temperature
1 tablespoon lemon juice
¼ teaspoon fine sea salt

Freshly ground black pepper
½ cup delicate (with low bitterness and pungency) extra-virgin olive oil
½ cup The Olive Oil Source natural lemon flavor infused olive oil

1 tablespoon cool water

For the asparagus:
2 pounds thin asparagus
Fine sea salt or fleur de sel
Freshly ground black pepper
1 tablespoon delicate (with low bitterness and pungency) extra-virgin olive oil
1 tablespoon The Olive Oil Source natural lemon flavor infused olive oil

Make the mayonnaise:
Put the egg yolks, lemon juice, salt, and a few grindings of pepper in the small bowl of a food processor. Mix the oils together. With the processor running, drizzle the oil through the feed tube, starting with a few drops at a time and gradually increasing to a thin stream. Add all the oil, then the water. If the mayonnaise is too thick for your taste, add a little more water. Transfer to a serving bowl, and refrigerate if not serving immediately.

Roast the asparagus:
Preheat a convection oven to 400°F and line two baking sheets with parchment paper. Break off the woody ends of each stalk: Grasp a stalk in both hands, one hand in the middle and the other at the stem end. With a flick of the wrist, remove the woody end. Put the stalks on the baking sheets in one layer. Liberally salt and pepper. Mix the oils together and drizzle on the asparagus. Roll the stalks so they are evenly coated. Bake until the stalks brown and the tips start to char, about 10 minutes. (Thicker stalks will take longer. Poke one with a skewer to see if they are done.)

Serve warm or at room temperature. Pass the lemon olive oil mayonnaise on the side.

This recipe also works well with our other The Olive Oil Source natural citrus flavor infused olive oils.
