Spaghetti with Clam Sauce (Gluten Free)

For properly cooked pasta → A large stock pot provides the space needed for generously salted water and allows pasta — especially gluten-free varieties — to move freely as it cooks, preventing sticking and promoting even texture. Ample volume ensures the water returns quickly to a boil, helping pasta cook consistently from start to finish. Shop the Stock Pot →

When surface area matters → A wide, enameled cast-iron skillet allows clams to open evenly and gives the pasta room to move and emulsify with the sauce. Shop the Braiser →

Step 1 — Cook the Pasta

Bring 2 quarts of well-salted water to a boil in a large stock pot. Add gluten-free spaghetti, stirring immediately to prevent clumping. Cook until just al dente, about 10 minutes. Reserve 1 cup of pasta cooking water, then drain.

Step 2 — Build the Base

While the pasta cooks, place a wide sauté pan or Dutch oven over medium-low heat. Add olive oil, garlic, and red pepper flakes. Cook gently until fragrant, taking care not to brown the garlic.

Step 3 — Steam the Clams

Add white wine, 1/3 cup reserved pasta water, and lemon juice. Increase heat to medium-high. Once the liquid reaches a low boil, add clams and cover. Cook until clams open, about 2–3 minutes. Discard any that remain closed.

Step 4 — Bring It Together

Add drained pasta directly to the pan. Toss gently and cook for 2–3 minutes, allowing the pasta to finish cooking and the sauce to thicken naturally. Add more pasta water as needed to loosen.

Step 5 — Finish & Serve

Remove from heat. Add half the parsley, half the Parmesan, and the lemon zest. Shake or toss the pan to distribute evenly.

Divide among bowls and finish with remaining parsley and cheese.

Chef Notes

• When purchasing clams, ask for a net, not a plastic bag. Clams need air — plastic suffocates them and shortens viability.

• Store clams on ice in the refrigerator and cook within 24 hours.

• This dish rewards simplicity — resist the urge to overwork it.

Chef Notes - Everything Clams

New England Clams: From Quahogs to Steamers

If there’s one shellfish that defines New England, it’s the clam. But not all clams are the same - and their size often determines how they’re cooked. Here’s the breakdown:

Quahogs (Hard Clams) - The most iconic clam in Rhode Island, dug from sandy bottoms. Quahogs are actually the same species (Mercenaria mercenaria), but their names change with size.

• Little Necks - The smallest (1–2 inches across). Sweet, tender, perfect raw on the half shell,

• Cherrystones - Medium (about 2–3 inches). Still good raw, often baked or grilled. Their balance of briny and chewy makes them versatile.

• Topnecks -Usually chopped for chowders or baked stuffies.

• Chowder Clams - The largest, often over 3 inches. Tougher, bold flavor, best in chowder or fritters.

• Mahogany Clams (Ocean Quahogs) - Found in the open-ocean, harvested in Maine. Fun Fact: Mahogany clams are some of the longest living animals on the planet, surviving up to 400 years if undisturbed. 

Steamers (Soft-Shell Clams) - Dug along sandy tidal flats, steamers have thin shells and a delicate, sweet flavor. Best eaten steamed with drawn butter, they’re also a staple in fried clam strips.

Razor Clams - Long, slender, and harder to find, razor clams are a delicacy.

Surf Clams - The giants, often harvested offshore, used for fried clam strips or chowder.
