In this supremely springy recipe, thick asparagus stalks and thinly sliced leeks are glossed with olive oil and covered in salty capers. Everything is roasted in the same pan and emerges tender and golden-edged. Capers also make an appearance in the mustard sauce served alongside, which adds a tangy, mayonnaise-like richness. You can double the recipe, if you wish, though you may have to increase the roasting time by a few minutes to make up for a more-crowded pan. Serve this on its own as a first course, or as an accompaniment to roast chicken, braised meats or seared fish. Just don’t use thin asparagus: It’ll cook too quickly, before the leeks have a chance to turn golden. Stick with spears that are at least ½ inch in diameter.

Preparation

  1. Step 1

    Heat oven to 425 degrees. Put asparagus on a rimmed sheet pan and toss with 1 tablespoon oil and ½ teaspoon salt until well coated.

  2. Step 2

    In a small bowl, stir together leeks, remaining 1 tablespoon oil, and a pinch each of salt and pepper. Sprinkle leeks on top of asparagus, then sprinkle with capers. Roast until asparagus are tender and golden brown, about 12 to 18 minutes.

  3. Step 3

    While the asparagus stalks roast, make the mustard sauce: In a small bowl, whisk together mustard, capers and garlic. Slowly whisk in olive oil a few drops at a time to create a thick, emulsified dressing. Season with salt and pepper to taste.

  4. Step 4

    Once asparagus stalks are out of the oven, squeeze a lemon wedge over it and sprinkle parsley on top. Serve with mustard sauce and more lemon wedges on the side.

Asparagus grow in length (not width) so plumper bottoms doesn't mean it's not fresh. As the article states, look at the tightly closed buds for freshness. As Jacques Pepin taught us, use a vegetable peeler to quickly remove the tougher out layer on fatter asparagus. This way, you won't be cutting and throwing away a delicious inch or two of the vegetable (you paid for). https://www.youtube.com/watch?v=pMH21I782IM&t=28s

Thicker asparagus are just from older plants. The asparagus council wants us to believe the thinner ones are better; it's easier for them to deal with younger plants (since asparagus is a perennial, which makes weeding harder and harder as years pass). The thick asparagus are the most special.

When roasting asparagas, I arrange them on a foil lined baking sheet with the tops aligned on one side of the pan so I can fold the foil over just the tops to prevent them from overcooking while the stalks get roasted and creamy inside. I like to roast lemon halves in the pan at the same time to squeeze directly over the spears or to make a piquant sauce like Melissa's mustard sauce recipe. Asparagus and sugar snap peas are quintessential spring delights.

When making the mustard sauce, start with the mustard in a small bowl and then drizzle the oil in while whisking. Then add the capers and garlic after. If you add everything to the same bowl all at once you'll probably end up with a broken sauce (it'll look oily and runny instead of like a thick aioli).

I don’t like Dijon mustard (sorry) but replaced it w Trader Joe’s lemon pesto and followed the rest of the recipe. It was perfect.

Sally

Parsley tho in list of ingredients, was omitted from the recipe. I added some to crisp up with the leeks. I reduced the capers to 1 tbs chopped up & mixed in with the leeks. Delicious. Will make again. Did a yoghurt, garlic, lemon & tahini mayo as had run out of Dijon mustard
