Ivars Clam Chowder Recipe: Pacific Northwest Creamy Bowl

This Pacific Northwest classic delivers a creamy, comforting bowl that captures the essence of Seattle’s waterfront tradition.

I’ve refined this method to balance tender clams, hearty potatoes, and a velvety broth that stays rich without being heavy.

Ingredients for Ivars Clam Chowder

Fresh clams, hearty potatoes, and a velvety broth create this Pacific Northwest staple.

The clams are non-negotiable here. Manila clams are traditional for Ivars-style chowder—sweet, tender, and briny. Taylor Shellfish (a Seattle institution) is the gold standard if you’re local, but most seafood counters will have them fresh. Look for clams that are tightly closed (or close when tapped) and smell like the ocean, not fishy. The Yukon Gold potatoes hold their shape better than russets, which can turn mealy in the broth.

No fresh clams? Canned clams in juice work in a pinch—drain the juice into your broth for extra flavor. Swap the white wine for extra clam juice if you’re avoiding alcohol. For a lighter version, half-and-half instead of heavy cream still gives richness without the weight. The thyme and bay leaves are classic, but a pinch of Old Bay seasoning nods to the regional roots without overpowering.

Chowder improves overnight as the flavors meld. Store in the fridge for up to 3 days, but don’t freeze it—the cream separates. Reheat gently on the stove, stirring often. If making ahead, undercook the potatoes slightly so they don’t turn to mush when reheated.

Step-by-Step Instructions for Creamy Clam Chowder

Master this Pacific Northwest classic with precise timing and technique for the richest results.

Step 1: Steam the Clams and Prepare the Base

In a large Dutch oven, melt ¼ cup of the unsalted butter over medium heat. Add the 2 lb Fresh Manila Clams and ½ cup dry white wine. Cover and steam for 5-7 minutes until every clam opens—discard any that remain closed after this time.

Strain the clam broth through a fine-mesh sieve into a bowl, reserving both the liquid and the clams. Remove the clams from their shells, chop them coarsely, and set aside. The strained broth should yield about 2 cups—supplement with the bottled clam juice if needed to reach this volume.

Step 2: Sauté the Aromatic Vegetables

In the same pot, melt the remaining ¼ cup unsalted butter over medium heat. Add the finely diced yellow onion and celery stalks, cooking for 5 minutes until softened but not browned. Stir in the minced garlic cloves and cook for 30 seconds until fragrant.

Add the all-purpose flour and whisk constantly for 2 minutes to create a pale roux. This step builds the foundation for your creamy base while cooking out the raw flour taste. The mixture should resemble wet sand and smell slightly nutty.

Step 3: Build the Creamy Broth

Slowly pour in the reserved clam broth and 2 cups clam juice, whisking continuously to prevent lumps. Add the bay leaves and stripped leaves from the fresh thyme sprigs. Bring to a gentle simmer over medium-high heat.

Add the peeled and diced Yukon Gold Potatoes, then pour in the heavy cream and whole milk. Season with 1 tsp kosher salt and ½ tsp freshly ground black pepper. Reduce heat to medium-low and simmer for 15-20 minutes until the potatoes are tender when pierced with a fork.

Step 4: Finish and Serve

Stir in the chopped clams and warm through for 2-3 minutes. Taste and adjust seasoning if needed—the flavors should be balanced with the briny clams, creamy broth, and subtle herbal notes from the thyme and bay.

Remove the bay leaves before serving. The chowder should have a velvety texture with visible flecks of clam and potato. Ladle into bowls while hot, and serve with crusty bread to soak up every last drop of the rich, creamy broth.

Common Mistakes When Making This Dish

Overcooking the Clams

Never let the clams simmer longer than 5-7 minutes in the wine. They turn rubbery fast—David and I learned this the hard way during our first test batch. Remove them as soon as the shells open, then chop and add back at the very end to warm through. 💡

Skipping the Roux

That 2-minute roux with butter and flour isn’t optional. It thickens the broth and prevents a floury taste. I whisk constantly over medium heat until it smells nutty. Skipping this step leaves your chowder thin and raw-tasting.

Rushing the Potatoes

Yukon Golds need 15-20 minutes at a gentle simmer to get tender without breaking apart. Cranking the heat boils the cream, causing curdling. I check with a fork—if it slides in easily, they’re done.

Using the Wrong Cream

Avoid low-fat substitutions here. Heavy cream and whole milk create that signature velvety texture. I’ve tried half-and-half, and it just doesn’t deliver the same richness for this Pacific Northwest classic.

Forgetting to Strain

Always strain the clam broth through a fine-mesh sieve after steaming. Sand and grit ruin the creamy texture. I press the clams gently to extract every bit of flavorful liquid.

Overseasoning Early

Clams vary in saltiness, so I wait until the end to adjust seasoning. Start with just 1 tsp kosher salt, then taste after adding the chopped clams. You can always add more, but you can’t take it out. 🌊
