Instructions

Step 1: Sauté the aromatics

In a large pot over medium-high heat, melt the butter with 1/2 tablespoon oil. Add the diced onion and cook for 3–5 minutes until soft and slightly golden. Stir in the chopped garlic and 1 tablespoon Cajun seasoning and cook for another minute until fragrant.

Step 2: Cook the sweet potatoes

Add the cubed sweet potatoes and the 4 cups of broth to the pot. Bring to a boil, then reduce heat and simmer for 10–15 minutes, or until the sweet potatoes are tender. Remove about half of the sweet potatoes and puree them in a blender or food processor; return the puree to the pot to create a creamy base while preserving some chunks for texture.

Step 3: Prepare the seafood

While the potatoes simmer, heat a skillet over medium-high heat. Toss the shrimp and scallops with 1 tablespoon oil and 1 tablespoon Cajun seasoning until evenly coated. Sear them for 2–4 minutes per side until golden brown and slightly crispy. Remove from the pan and set aside.

Step 4: Combine and finish

Stir the fish sauce, corn, chopped tarragon, and lemon juice into the chowder. Taste and adjust seasoning with salt, pepper, and more Cajun seasoning if desired. Let the chowder simmer for an additional 5 minutes so the flavors meld.

Step 5: Serve

Ladle the chowder into bowls, top with the seared shrimp and scallops, and garnish with extra tarragon. Serve alongside crusty bread or a simple green salad for a balanced meal.

Helpful tips

• Use fresh seafood when possible. Frozen shrimp and scallops work well if fully thawed and patted dry to ensure a good sear.
• Control the heat by adjusting the amount of Cajun seasoning. Add a pinch of cayenne for extra spice or reduce the seasoning for a milder result.
• Adjust consistency by blending more or less of the cooked sweet potatoes. Add extra broth to thin the chowder or blend additional potatoes to thicken it.
• Proper searing requires a hot pan and dry seafood. Don’t overcrowd the pan—sear in batches if needed to maintain a golden crust.

Best cooking techniques

• Use a heavy-bottomed pot to prevent scorching and to distribute heat evenly while simmering the chowder.
• An immersion blender lets you adjust texture easily; blend just part of the potatoes to keep a pleasing mix of creamy base and bite-sized chunks.
• Sear seafood quickly over high heat to keep it tender inside while achieving a flavorful crust outside.

Serving suggestions

• Crusty bread or a warm baguette for soaking up the chowder.
• A light green salad with lemon vinaigrette to brighten the meal.
• A crisp, dry white wine such as Sauvignon Blanc or Pinot Grigio complements the seafood and spices.

Is there a vegan version?

Can I change the seasoning?
