Dump a frozen lump crab meat block in the slow cooker and 3 other ingredients to get a meal so delicious your family will be begging for more!

This 4-ingredient slow cooker tax day crab chowder is the kind of recipe you make when your brain is fried from paperwork but you still want something that tastes like you tried. It leans on a frozen block of lump crab meat and three pantry-friendly helpers to create a surprisingly rich, coastal-style chowder with almost no effort. While traditional crab chowders often start with a roux and a sauté of aromatics, this version is unapologetically streamlined: you literally dump everything into the slow cooker—starting with that frozen crab block on the bottom—set it, and walk away. A few hours later, you’ve got a creamy, briny bowl that feels restaurant-worthy with a fraction of the work.

Serve this crab chowder steaming hot in wide bowls with a handful of oyster crackers or crusty baguette slices for dipping. A simple green salad with a lemony vinaigrette balances the richness nicely, and a side of roasted asparagus or green beans keeps the meal feeling light. If you enjoy wine, a chilled glass of crisp white—like Sauvignon Blanc or an unoaked Chardonnay—plays well with the sweet crab. For a cozier, budget-minded pairing, offer hot buttered toast or garlic bread and a squeeze of fresh lemon at the table to brighten each bowl.

Servings: 4

1 pound frozen lump crab meat block (do not thaw)

Place the frozen lump crab meat block in the bottom of a 4- to 6-quart slow cooker. The crab should go in first so it gently thaws and infuses the liquid as it cooks.

Pour the seafood stock (or broth) evenly over the frozen crab block, making sure the bottom of the slow cooker is mostly covered with liquid.

Add the frozen diced hash brown potatoes on top of the crab and stock, spreading them into an even layer. Do not stir; keeping the crab at the bottom helps it stay tender.

Pour the evaporated milk over the potatoes and crab. Again, no need to stir—everything will come together as it heats.

Cover the slow cooker with the lid and cook on LOW for 4 to 5 hours, or until the potatoes are very tender and the crab has fully thawed and warmed through. Avoid opening the lid in the first few hours so the soup maintains a steady temperature.

Once the potatoes are soft, gently stir the chowder, breaking up the crab block into large flakes. Taste and, if desired, season lightly with salt and pepper or your favorite seafood seasoning, keeping in mind that some stocks are already salty.

Ladle the hot crab chowder into bowls and serve immediately. If you like, garnish with a sprinkle of paprika, chopped fresh parsley, or a squeeze of lemon at the table (all optional and not counted among the core four ingredients).

To keep this recipe true to its spirit—dump, cook, and walk away—any variations should still respect the four-ingredient core. You can swap the seafood stock for chicken broth if that’s what you have; the flavor will be slightly less briny but still comforting. For a thicker chowder, lightly mash some of the potatoes against the side of the slow cooker with a spoon right before serving. If you want a touch of smokiness without adding more core ingredients, finish bowls with a pinch of smoked paprika or a few drops of hot sauce. For a slightly more indulgent version, you can replace 1 cup of the evaporated milk with heavy cream, but only do this at the end of cooking and warm it through gently to avoid curdling. Food safety tips: Make sure the frozen crab meat you use is from a reputable source and kept fully frozen until you’re ready to cook. Always cook the chowder on LOW, not WARM, so it passes through the temperature danger zone (40°F–140°F / 4°C–60°C) quickly enough. The chowder should reach at least 165°F (74°C) before serving. Cool leftovers promptly and refrigerate within 2 hours in shallow containers; reheat gently on the stovetop or in the microwave until steaming hot. Because this chowder contains seafood and dairy, consume leftovers within 2 days for best quality and safety.
