There’s something deeply satisfying about a bowl of creamy clam chowder that captures the essence of New England comfort. This recipe delivers the perfect balance of tender clams, hearty potatoes, and a velvety broth that warms you from the inside out.

Every spoonful offers that ideal combination of briny ocean notes, creamy richness, and smoky depth. Whether you’re feeding a crowd or treating yourself, this chowder brings restaurant-quality results to your home kitchen.

Ingredients for Mos Clam Chowder

Fresh clams, crispy bacon, and hearty potatoes come together for that iconic New England comfort.

The clams are everything here. Littlenecks or cherrystones work best—avoid pre-shucked if possible (they lose that briny sweetness). I grab mine from Whole Foods or a trusted fishmonger the same day I’m cooking. The bacon? Thick-cut gives you those perfect chewy bits. For potatoes, Yukon Golds hold their shape but get creamy—don’t skip peeling them. And that clam juice? Bar Harbor brand is my go-to for consistent flavor (find it near the canned tuna).

No fresh clams? Canned clams in juice work in a pinch—drain and rinse first. Swap the bacon for smoked turkey bacon if you need to, though the flavor won’t be as deep. Out of clam juice? Fish stock plus a splash of lemon gets you close. The cream is non-negotiable for that velvety texture, but full-fat coconut milk can work for dairy-free (just know it’ll taste different). Fresh thyme is ideal, but 1 teaspoon dried works if that’s what you’ve got.

Chowder tastes even better the next day—store in the fridge for up to 3 days. Freeze without the cream (add fresh when reheating) for up to 3 months. The bacon will soften when stored, so I always make extra to sprinkle on top when serving. Pro tip: keep the parsley separate until serving to maintain that fresh pop of color.

Step-by-Step Instructions for Mos’ Clam Chowder

Here’s how to build that perfect balance of creamy texture and briny clam flavor in every spoonful.

Step 1: Render the Bacon and Sauté Aromatics

Start with a heavy-bottomed pot or Dutch oven over medium heat. Add the 6 oz thick-cut bacon and cook for 6-8 minutes, stirring occasionally, until the fat renders out and the bacon becomes crispy and golden brown. I like to use tongs to turn the pieces so they cook evenly without burning.

Once the bacon is crisp, use a slotted spoon to transfer it to a paper towel-lined plate, leaving the rendered fat in the pot. This fat is pure flavor—don’t discard it. To that same pot, add the finely diced yellow onion and finely diced celery stalks. Cook for 5-6 minutes until the vegetables soften and become translucent but not browned. The aroma will shift from sharp to sweet—that’s your cue they’re ready.

Step 2: Build the Flavor Base with Potatoes and Broth

Add the 1.5 lb Yukon Gold potatoes (cut into ½-inch cubes) to the pot along with the 4 tbsp unsalted butter. Stir to coat the potatoes in the butter and bacon fat, then cook for 3-4 minutes until the butter foams and the potatoes start to develop a slight golden color on their edges.

Sprinkle the 0.25 cup all-purpose flour over everything and stir constantly for 2 minutes—this creates a light roux that will thicken your chowder beautifully. The mixture should look like wet sand and smell nutty. Slowly pour in the 2 cups clam juice, stirring continuously to prevent lumps. Add the 1 tbsp fresh thyme and 1 whole bay leaf, then bring the mixture to a gentle simmer.

Step 3: Simmer the Chowder Until Potatoes Are Tender

Reduce the heat to medium-low and let the chowder simmer uncovered for 12-15 minutes, or until the potatoes are fork-tender but still hold their shape. You’ll notice the broth thickening slightly and the potatoes becoming translucent around the edges. Stir occasionally to prevent sticking, and keep an eye on the heat—you want a gentle bubble, not a rolling boil.

While the potatoes cook, scrub the 2 lb fresh littleneck clams under cold running water, discarding any that are already open or cracked. Once the potatoes are tender, add the clams to the pot, cover with a lid, and steam for 5-7 minutes until all the clams open. Discard any clams that remain closed after this time—they’re not safe to eat.

Step 4: Finish with Cream and Seasonings

Remove the pot from heat and discard the bay leaf. Stir in the 1.5 cups heavy cream and 1 cup whole milk, combining gently so you don’t break up the potatoes or clams. Return the pot to low heat and warm through for 3-4 minutes—just until the chowder is hot but not boiling. Boiling at this stage can cause the cream to separate.

Season with the 1.5 tsp kosher salt and 0.5 tsp freshly ground black pepper, then taste and adjust if needed. The clams and bacon should provide enough saltiness, but I always recommend tasting before serving. Stir in the crispy bacon you set aside earlier, reserving a little for garnish if you like that extra crunch in every bite.

Step 5: Rest and Serve with Fresh Herbs

Let the chowder rest off heat for 5 minutes before serving—this allows the flavors to meld together. The chowder should be creamy but not too thick, with visible chunks of potato, clams, and bacon throughout. If it’s thicker than you prefer, stir in a splash of whole milk to loosen it slightly.

Ladle the chowder into warm bowls and garnish each serving with the 2 tbsp fresh flat-leaf parsley and any reserved bacon. The parsley adds a fresh contrast to the rich, creamy base. Serve immediately with crusty bread or oyster crackers for soaking up every last drop. The clams should be plump and tender, the potatoes soft but not mushy, and the broth velvety with just the right amount of briny depth.

Common Mistakes When Making This Recipe

Overcooking the Clams

The moment those clams open, they’re done—keep cooking and they turn rubbery fast. I pull mine out after exactly 5-7 minutes of steaming, testing one with a fork. If it’s plump but resists slightly, it’s perfect. Closed clams after cooking? Toss them—they’re unsafe to eat. 🐚

Boiling the Cream

This is the fastest way to ruin your chowder. When adding the 1.5 cups heavy cream, keep the heat on low and watch for tiny bubbles at the edges—never let it reach a full boil. I stir constantly and pull it off heat if it gets too hot. Curdled cream is heartbreaking after all that work.

Skipping the Roux

That 2 minutes of cooking the ¼ cup flour with butter isn’t optional—it removes the raw flour taste and creates the perfect thickener. I cook until the mixture smells nutty and turns pale golden. Rushing this step leaves your chowder tasting like wet dough.

Using Pre-Shucked Clams

Fresh littleneck clams in their shells add so much more flavor than pre-shucked. The steaming process infuses the broth with briny sweetness you just can’t get from canned. If you must use pre-shucked, at least save the juices and add them with the clam juice for extra depth.

Over-Salting Early

The clams and bacon contribute significant saltiness, so I always wait until the very end to adjust seasoning. Start with just ½ tsp kosher salt during cooking, then taste before adding more. You can always add salt at the table, but you can’t take it out once it’s in there.

Ignoring Potato Size

Those ½-inch cubes of Yukon Gold aren’t arbitrary—they cook evenly in 12-15 minutes without turning to mush. Larger chunks stay raw inside while smaller ones dissolve. I use a ruler the first few times until my knife skills get consistent. Uniformity is key for perfect texture.
