Roasted Asparagus with Creamy Lemon Cardamom Sauce

I don’t think I’ve ever loved a veggie side dish more than I love this Roasted Asparagus with Lemon Cardamom Sauce.  Bold statement, I KNOW, but hear me out.

We take what is quite possibly the easiest vegetable in the history of all vegetables to cook, and we jazz it up with a sauce that is so incredible that I can sum it up in one word: HEAVEN.  We’ve got butter for a rich flavor, lemon for a bright, fresh tang, and cardamom for a subtle spice that really makes this dish special!

Asparagus is that one vegetable that I’ve just continued to fall in love with a little more each time I serve it.  I love that it’s so very versatile in terms of what you can do with it!  Saute it with some butter or olive oil for a nice quick side.  Blanch it quickly to keep that fresh, crisp snap, or roast it to bring out the deep flavors and crunchy potential. Most of the time we do ours fairly plain, with a little oil and seasoning, but this Roasted Asparagus with Lemon Cardamom Sauce is my new favorite way to go!

Not only is the roasting process so easy and hands-off, but the sauce itself comes together in minutes – it’s as simple as taking all of your sauce ingredients (grass-fed butter, mayo, lemon juice, turmeric, and cardamom) and whisking them together until they’re smooth.  The bright yellow hue from the turmeric, plus the contrast of the black sesame seeds make this dish one that looks fancy enough to serve at a dinner party, but easy enough to make for your weeknight dinners. It’s the perfect side!

Frequently Asked Questions

When is asparagus season?

Grocery stores carry asparagus year-round, but its peak is in the Springtime – April and May specifically. If you’re buying asparagus at the grocery store in the fall or winter, it’s likely that it’s traveled quite a distance to get to you.

How do you make asparagus crispy not soggy?

In order to avoid soggy asparagus, be sure to coat each veggie in olive oil, and use the temperature and timing guidelines in this recipe. Roasting the asparagus at 425°F allows for a really nice, crisp finished texture.

Should I soak asparagus before roasting?

No need to soak your asparagus before roasting! While you may come across some recipes that recommend this, you can rest assured that this recipe does not require the additional step.

What part of asparagus should you not eat?

We recommend cutting off the woody ends of your asparagus (the bottom two-ish inches of each spear). There isn’t necessarily anything *wrong* with this part of the asparagus – it’s just tough and not super enjoyable to eat.
