Ivar's Famous Clam Chowder Recipe: Thickened With Potatoes and Smoky Bacon Bits

Ivar's clam chowder recipe delivers the rich, creamy comfort of New England's most iconic seafood soup—thickened with tender potatoes and smoky bacon bits that transform every bite into a taste of tradition.

The secret lies in slow-simmered broth, fresh clams (or canned for convenience), and a blend of thyme and bay leaf that builds deep, savory layers. I've perfected this version over years of testing, ensuring the perfect balance between hearty texture and delicate seafood flavor.

What sets this chowder apart is the two-stage thickening technique: potatoes create a natural roux while simmering, then cream adds luxurious body without breaking the delicate flavors.

The bacon adds a subtle smokiness that cuts through the richness, while clams bring that briny freshness that defines coastal New England cuisine. Every spoonful delivers that signature creamy, satisfying mouthfeel that makes this soup legendary.

This recipe builds on Ivar's original while making it foolproof for home cooks—no special equipment required, just patience and attention to simmering times.

The result is a bowl of chowder so rich and comforting it feels like a hug on a cold day, with just the right amount of creaminess to coat every bite.

Serve it piping hot with oyster crackers or crusty bread to soak up every last drop of that golden, flavorful broth.

Whether you're recreating a classic from Seattle's iconic Ivar's Acres or simply craving a hearty seafood soup, this version stays true to tradition while being adaptable to your kitchen.

The beauty of this recipe lies in its flexibility—use fresh clams for the ultimate experience, or canned for convenience without sacrificing flavor. The smoky bacon bits add that signature touch that makes this chowder instantly recognizable and irresistibly delicious.

Ingredients for ivar's clam chowder

Sixteen ingredients, one legendary bowl of chowder—where New England tradition meets home kitchen perfection.

The clams are the soul of this chowder, so prioritize quality. Fresh steamed clams from a trusted seafood market deliver unmatched brininess, but high-quality canned clams (like Bumble Bee or Wild American) work beautifully for convenience. If using fresh, steam them open first—discard any that don’t open. The bacon should be thick-cut and smoked for that signature smokiness; Oscar Mayer or Applegate brands are reliable choices. For the potatoes, Yukon Golds add creaminess, but Russets hold up perfectly during long simmering. The thyme and bay leaves should be fresh if possible—dried works, but Penzeys or McCormick organic blends elevate the depth of flavor. Store fresh herbs in the fridge wrapped in damp paper towels for up to 5 days to preserve their aromatic oils.

No fresh clams? Canned clams in juice (not water) maintain flavor—just drain them well before adding. Running short on bacon? Smoked turkey bacon or pancetta deliver similar depth, though bacon’s smokiness remains irreplaceable. The potatoes should be peeled and cubed uniformly—this ensures even cooking and a velvety texture. For the broth, homemade is ideal, but Swanson or Pacific Foods low-sodium options work in a pinch. The heavy cream must be full-fat for authentic richness—Hormel or Organic Valley are excellent choices. If you’re avoiding dairy, full-fat coconut milk can substitute, though the flavor profile shifts slightly. The olive oil should be extra-virgin for rendering the bacon; California Olive Ranch or Bertolli are dependable brands that won’t overpower the dish.

This chowder tastes even better the next day as flavors meld, so double the batch if you’re feeding a crowd. Store leftovers in an airtight container in the fridge for up to 4 days—the cream may separate slightly, but a quick stir restores its lusciousness. For longer storage, freeze portions in airtight, freezer-safe containers for up to 3 months. To reheat, warm gently on the stove over medium-low heat, stirring occasionally, until heated through. Avoid microwaving, as it can break the cream’s emulsion. Serve with oyster crackers or crusty sourdough to soak up every last drop of that golden, flavorful broth—the true hallmark of Ivar’s legendary chowder.

Step-by-step instructions for Ivar's famous clam chowder

This chowder delivers the signature Ivar's experience—creamy yet robust, with tender clams and smoky bacon.

In a large, heavy-bottomed pot, cook the 12 oz thick-cut bacon over medium heat for 12-15 minutes, stirring occasionally, until the fat is rendered and the bacon is deep golden brown and crisp. Use a slotted spoon to remove the bacon and set it aside on paper towels to drain excess fat, reserving ¼ cup of the rendered bacon fat in the pot.

In the same pot, add ¼ cup extra-virgin olive oil to the reserved bacon fat, then increase heat to medium-high. Add the 1 whole yellow onion and 3 whole celery stalks, both diced, and cook for 5-6 minutes until softened and lightly golden. Stir in the 4 cloves garlic cloves and 2 tbsp fresh thyme, cooking for an additional 30 seconds until fragrant. This aromatic base forms the flavor foundation of the chowder.

Add the 2 lbs russet potatoes, cut into 1-inch cubes, to the pot. Pour in the 4 cups chicken broth and bring to a gentle boil. Reduce heat to medium-low, cover, and simmer for 12-15 minutes until the potatoes are fork-tender but not falling apart. Stir occasionally to prevent sticking.

Here's the thing—you want the potatoes to break down slightly but still hold their shape. If they're mushy, the chowder will lose its signature thick, creamy texture. Taste the broth to ensure it's absorbing the flavors from the aromatics and bacon.

While the potatoes cook, prepare the 2 lbs fresh clams. Scrub them under cold water to remove any debris, then place them in a colander. Add the 2 whole bay leaves to the pot with the potatoes and clams, then cover and steam for 5-7 minutes until the clams open. Discard any clams that remain closed.

Once the clams are open, use a slotted spoon to transfer them to a bowl, reserving the clam juice in the pot. Remove the bay leaves and discard them. Stir in the 1.5 cups heavy cream and 1 cup whole milk, then simmer the mixture for 3-4 minutes until slightly thickened. The cream should coat the back of a spoon, indicating it's ready for the next step.

Add the opened clams and their reserved juice back to the pot. Stir in the 1.5 tsp diamond crystal kosher salt and 0.5 tsp freshly ground black pepper, then return the crispy bacon to the pot. Simmer for an additional 2-3 minutes to meld all the flavors together. The chowder should be thick, creamy, and rich, with tender clams and crisp bacon bits throughout.

Taste and adjust the seasoning if needed. The chowder should be salty, slightly sweet from the clams, and smoky from the bacon. Serve immediately in deep bowls, garnished with a sprinkle of fresh thyme or extra crispy bacon for added texture. This chowder is best enjoyed fresh, as the creaminess and flavors are at their peak when served hot.

Creative variations of ivar's clam chowder

Smoky Bacon Variations

Skip the bacon entirely for a vegetarian version—I swap it with 4 oz smoked paprika mixed into the olive oil for a similar smoky depth. For extra richness, add 2 tbsp nutritional yeast to mimic bacon's umami.

If you prefer meat but want variety, try andouille sausage (about 8 oz) instead of bacon for a Cajun-inspired twist. 🥓

Seafood Swaps

Fresh clams are ideal, but you can substitute with 1 lb chopped scallops or 12 oz cooked shrimp for a lighter texture. For a fish-forward version, add 1 lb white fish (like cod or haddock) cut into chunks.

I also love adding 4 oz chopped mussels alongside clams for extra brininess. Always steam seafood separately and add it back at the very end to keep it tender.

Dairy-Free Creaminess

For a dairy-free version, replace the heavy cream and milk with 2 cups full-fat coconut milk and ½ cup unsweetened almond milk. Stir in 1 tbsp cornstarch mixed with 2 tbsp water to thicken properly.

The coconut adds a subtle sweetness that pairs beautifully with the smoky bacon and clams. 🌱

Spicy Kick Options

Add 1 tsp smoked paprika and ½ tsp cayenne pepper to the bacon fat for a smoky-spicy chowder. For heat lovers, stir in 1-2 tbsp hot sauce (like Louisiana or Tabasco) at the end.

I also recommend adding 1 diced jalapeño (seeds removed) when sautéing the aromatics for a slow-building heat.

Swap thyme for 2 tbsp fresh parsley and 1 tbsp fresh dill for a brighter, Mediterranean-inspired chowder. Add 1 sprig fresh rosemary when cooking the potatoes for an earthy depth.

For a citrus note, zest 1 lemon and add it with the cream, then finish with a squeeze of fresh lemon juice before serving.

For a New Orleans-style version, add 1 tsp filé powder (made from ground sassafras) at the end—it thickens and adds an earthy flavor. A Pacific Northwest adaptation might include 1 tbsp fresh cilantro and a splash of local seafood stock instead of chicken broth.
