Mussels are the perfect choice for a weeknight meal. They’re a terrific source of low-fat protein, they’re inexpensive, they cook up quickly, and as they cook, they automatically generate tasty juices to whichever sauce you’re making.

Here I’ve dressed the mussels in green for St. Patrick’s Day with a garnish of chopped scallions and cilantro.

Coloring aside, the flavoring of this dish, consisting of just six ingredients, is Thai. The key actors are coconut milk and Thai curry paste, which are combined. (Don’t confuse coconut milk with cream of coconut, which has lots of sugar added.)

So how about trying this six-ingredient recipe the next time you want to mix it up a bit on a weeknight? You’ll have a delicious dinner on the table in just 30 minutes. And don’t forget to put some bread on the side. It’s just the thing to sop up all those juices.

Steamed Mussels in Spicy Coconut Broth

Start to finish: 30 minutes

Servings: 4

¼ cup Thai green curry paste

One 13.5-ounce can light coconut milk

3 pounds farmed mussels, scrubbed

1 to 2 tablespoons fresh lime juice or to taste

1/3 cup thinly sliced scallions

1/3 cup chopped fresh cilantro

In a large saucepan or stockpot whisk together the curry paste and coconut milk. Add the mussels, cover tightly and bring the liquid to a boil over high heat. Stir often. After a few minutes, the mussels should start to open. Remove them as they open and transfer them to a large bowl. If any mussels do not open, discard them. Add the lime juice to the saucepan and return all of the opened mussels to the saucepan and cook for a minute or two, stirring, to reheat them.

To serve, transfer the mussels to each of four soup plates. Pour one-fourth of the cooking liquid over each portion and sprinkle one-fourth of the scallions and cilantro over each one.
