Slow Cooker Chili Lime Butter Seafood Boil Tips, FAQ & printable recipe

Tips for success

For the best flavor, use high-quality snow crab clusters and fresh, wild-caught shrimp if available. The quality of the seafood really shines through in this simple preparation.

If you can't find snow crab, king crab or Dungeness crab are excellent substitutes—just adjust the cooking time if the pieces are larger or thicker.

Serve this dish with crusty bread or warm cornbread to soak up every last drop of the chili lime butter sauce. The sauce is so good you'll want to mop it up.

If you have leftovers, store them in an airtight container in the refrigerator and reheat gently to avoid overcooking the seafood.

Variations

• Spicy Cajun Twist: Replace the chili lime seasoning with Cajun seasoning and add a few dashes of hot sauce to the butter. This gives the dish a smoky, spicy kick that pairs wonderfully with the sweet corn and crab.
• Garlic Herb Butter: Swap the chili lime seasoning for a mix of dried oregano, thyme, and a pinch of red pepper flakes. Use fresh parsley instead of cilantro for a more traditional herb-forward flavor.
• Add Smoked Sausage: For a heartier meal, slice and add 1/2 pound of smoked sausage to the slow cooker with the seafood. The sausage adds a savory depth that complements the butter sauce. Keep in mind that this adds a protein and may require a longer cooking time if the sausage is raw.
• Citrus Herb Marinade: Instead of chili lime butter, use a mixture of melted butter, lemon juice, minced garlic, and fresh dill. This creates a lighter, more delicate sauce that lets the seafood flavor shine.

Storage and make-ahead

Fridge

Keep leftovers in the fridge in a sealed container for up to 3 days. Reheat gently to preserve texture.

Freezer

Freeze in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.

Reheat

Reheat in a skillet over medium-low heat, adding a splash of water or butter to refresh the sauce. Avoid boiling.

Store leftovers in an airtight container in the refrigerator for up to 3 days. The flavors will meld and intensify overnight. When reheating, do so gently in a skillet over low heat or in the microwave at 50% power to avoid rubbery shrimp.

You can prepare all the ingredients ahead of time—clean the shrimp, smash the garlic, and mix the butter seasoning. Store them separately in the refrigerator.

When ready to cook, simply layer everything in the slow cooker and turn it on. This makes it easy to have dinner ready when you get home.

Serving ideas

Serve this seafood boil over steamed jasmine rice to soak up the buttery sauce. The rice provides a neutral base that lets the chili lime butter shine. Add lemon wedges on the side for a bright, citrusy contrast. A sprinkle of extra cilantro on top adds freshness and color.

For a more casual presentation, you can serve the seafood boil directly from the slow cooker, letting everyone help themselves. Provide small bowls for the shells and plenty of napkins.

This dish is meant to be enjoyed with your hands, so don't be shy about getting messy. It's a fun, interactive meal that's perfect for gatherings.

Slow Cooker Chili Lime Butter Seafood Boil

Prep 10 minCook 3 hRest 5 minTotal 3 h 15 minServes 6

Ingredients

• 2 lb snow crab clusters
• 2 lb raw jumbo shrimp, peeled and deveined
• 2 cups frozen sweet corn kernels
• 12 cloves garlic, smashed
• 1/2 cup unsalted butter, melted
• 2 tbsp chili lime seasoning
• 1/4 cup fresh cilantro, chopped
• Steamed jasmine rice, for serving
• Lemon wedges, for serving

Instructions

1. Place the snow crab clusters and raw jumbo shrimp into the slow cooker basin in an even layer. Scatter the sweet corn kernels and smashed garlic cloves over the seafood, distributing them evenly so every bite gets a bit of corn and garlic.
2. In a small bowl, stir together the melted butter and chili lime seasoning until well combined. The mixture should be smooth and fragrant with a warm amber color from the spices.
3. Drizzle the chili lime butter evenly over the seafood, corn, and garlic. Use a spatula to scrape every last bit of the butter from the bowl. Gently toss the ingredients with a spoon to coat everything lightly, being careful not to break the crab clusters.
4. Cover the slow cooker and set it to low heat. Cook for 3 hours, or until the shrimp are opaque and the crab is heated through. Avoid lifting the lid during cooking to keep the heat and moisture inside.
5. Once the seafood is cooked, sprinkle the chopped cilantro over the top. Stir gently to incorporate the cilantro into the butter sauce, letting it wilt slightly from the residual heat.
6. Spoon the steamed jasmine rice onto a large serving platter or individual plates. Using a slotted spoon, lift the seafood, corn, and garlic from the slow cooker and arrange them over the rice. Drizzle with extra butter sauce from the slow cooker and serve with lemon wedges on the side.
