Grilled Clams with Lemon Orzo and Pesto Recipe

Don’t be intimidated by your grill

Don’t let the grill scare you off. Grilled clams look wildly impressive but are honestly one of the easiest things you can throw over the flames. Just set them on the grates and wait for the shells to pop open—done. No flipping, no fussing, no second-guessing yourself. They’re a total showstopper for any summer hang. Piled over preserved lemon orzo with a hit of grapefruit pesto and a drizzle of Calabrian chili oil, they’re basically the perfect dinner party move when you want to put in minimal effort and get maximum applause.

Everything you need to make this recipe

There are three main players here: the clams (obviously), the orzo, and a punchy, citrusy pesto. If you’re cooking this for a dinner party (highly recommend), you can knock out the pesto and the orzo a day ahead, then grill the clams while everyone’s hanging around with a glass of something cold in hand.

[For the pesto] Basil + mint + pistachios + grapefruit zest & juice + olive oil + S&P + icy cold water: It’s a simple blend with major flavor. The grapefruit brings a hit of brightness and acidity that keeps it from feeling too heavy—fresh, zippy, a little unexpected.

[For the orzo] Olive oil + orzo + butter + preserved lemons + chicken broth + black pepper. Buttery, lemony, salty in all the right ways, and honestly pretty hard to stop eating straight from the pot. It’s exactly the kind of starchy backdrop you want for piling on clams and spooning over pesto.

[For the clams] Clams + Calabrian chili oil. They really don’t need much—just a hot grill to pop them open and release all that briny goodness. A drizzle of Calabrian chili oil over the top adds just enough heat to cut through all the sunny citrus vibes.

Kitchen equipment needed:

chef’s knife
blender or small bullet blender
large skillet + stirring spoon
outdoor grill (gas or charcoal) + grill tongs
wide rimmed plate for serving (at least 12” wide)

How to make this grilled clams entrée

1. Make the pesto

Toss everything into a blender or food processor and blitz until it’s smooth and creamy. That’s it. No need to overthink it.

2. Make the orzo

Start by sautéing the preserved lemons in a little olive oil—this wakes them up and makes the whole kitchen smell amazing. Add the orzo to get it nice and toasty, then pour in the broth and simmer until tender. Finish with a generous knob of butter to make it extra rich and glossy.

3. Grill the clams

Get your grill hot and lay the clams right on the grates. They’ll start to pop open in just a few minutes. If you’re hosting, this is the perfect window to hand out some snacks and pour more wine.

4. Assemble

Dump the orzo onto a big serving platter, pile the grilled clams over the top, and drizzle everything with the pesto. Finish with a hit of Calabrian chili oil and, if you’re feeling fancy, some grilled lemon halves for squeezing over at the table.

Servings and pairings

These grilled clams are basically begging for a cold glass of something light and bright - the kind of wine you want to drink outside while the sun’s still up. Think crisp, mineral-driven whites like a Vermentino or Albariño, or even a chilled bottle of Muscadet if you’re feeling a little fancy. If you’d rather pop open something sparkling, a dry pét-nat or classic Brut will keep things lively.

Serve this as the centerpiece of a summer dinner party, a casual backyard hang, or any excuse to eat outside with friends. It’s colorful, packed with flavor, and light enough that everyone will still have room for dessert (or another round).

Storage and make ahead recommendations

If you’re making this for a dinner party, you can get a head start. The pesto and orzo are totally fine to prep ahead, but the clams are best served fresh, hot off the grill.

The day before

Make the pesto: Blend everything up and stash it in the fridge overnight.

Make the orzo: Cook the orzo according to the recipe below then store in the fridge overnight.

The day of

Reheat the orzo: Add it to a large skillet over medium-low heat with a splash or two of broth to loosen it up. Warm it through until it’s nice and creamy again.

Grill the clams: Toss them on the grill and let them open up—takes just a few minutes.

Assemble: Spread the orzo out on a big platter, pile on the clams, spoon over the pesto, and finish with a drizzle of chili oil. Done.

The pesto will be the brightest and most vibrant if you make it the day you’re serving, but it still tastes (and looks) great after a night in the fridge. The orzo will keep for up to 4 days in an airtight container, and any leftover clams should be refrigerated within 2 hours and eaten within 2–3 days.

Recipe FAQs

Can I make the pesto without grapefruit?
Definitely. If you’d rather skip the grapefruit, swap in lemon or lime juice and zest for brightness. It won’t have quite the same flavor, but it will still be fresh and citrusy.

What’s the best way to clean clams before grilling?
Give them a good scrub under cold running water to remove any grit on the shells. Then soak them in a bowl of cold water with a handful of salt for about 20–30 minutes. This helps them purge any sand inside. Rinse again before cooking.

Can I cook the clams another way if I don’t have a grill?
Absolutely. You can steam them in a pot with a splash of white wine or broth. Just cover and cook over medium heat until they pop open (usually about 5–7 minutes).
