How to make garlic butter seafood boil
Make Cajun seasoning mix: Gather all ingredients for the seasoning mix.
Melt unsalted butter: In a heavy bottom medium cooking pot or large cooking pan, melt butter over medium heat.
Add minced garlic: When butter has melted completely, add the minced garlic and cook for 5 minutes.
Cook garlic in butter: Remember to stir occasionally so the garlic won't stick to the bottom of the pan and burn.
Add seasoning: Add the rest of seasoning mixture to the butter garlic mixture, constantly stir for another 6-8 minutes to prevent the mixture from scorching (still use medium heat setting).
Cook vegetables: In a separate pot, start cooking corns and potatoes.
Make finishing mixture: Gathering ingredients for finishing mixture, then set them aside for later use.
Add vegetables/sausages: Start adding corns, potatoes and sausages to seasoning mixture. Coat them evenly with the sauce and let them cook for 5-8 minutes. Make sure to stir the mixture occasionally to prevent the bottom from burning.
Add seafood of your choice: Add uncooked seafood of your choice (such as shrimps, crawfish, clams, or mussels).
Cook seafood: Coat the seafood completely with Cajun seasoning mix and let them cook on medium-high heat for 10-15 minutes or until they are fully cooked.
Cover the seafood: When seafood are cooked completely, quickly turn off the heat, cover the cooking pan and let them rest for 5-10 minutes.
Mix with finishing mixture: Move the seafood and vegetables with half or one third of the sauce to a large mixing bowl. Then when the seafood are still hot, immediately add finishing mixture into the bowl.
Mix well: Use a large spoon, mix and coat the cooked seafood and vegetables evenly with finishing mixture. Serve hot immediately
Essential cooking tools
This Cajun style seafood boil calls for a lot of garlic. So to make the job easier, there are some tools that can actually help to speed up the cooking process.
Remember the more finely the cloves are crushed, the stronger the flavor will be. And make sure you include all of the garlic juice in the sauce. They're gold, don't throw them away.
- Granite mortal and pestle: If you making small batch of the recipe, this mortal comes in very handy. In fact this is what I often use whenever I make this butter garlic seafood boil recipe.
- Tuperware chop'n'prep: This small chopper is amazing and a very good tool to chop garlic as well as other herbs and vegetables. Don't underestimate its size, it can mince more garlic than it looks with just a few pull.
- Food processor: If you have extra budget, you can go all out for a food processor. Regardless of how big a batch you're gonna make, it can handle all of your minced garlic needs.

While a finishing mix is a touch up and added after everything is cooked and right before serving time.
Finishing mix help to enhance the flavors and bring out the goodness of this best garlic butter Cajun seafood boil.
Yes, definitely. You'll need to pre-cook big size of seafood before adding them into the Cajun sauce.
Yes, you can. Just remember to completely thaw them at room temperature before adding to the cooking pot. If not, their coldness will bring down the cooking temperature significantly and the extra water will do more damage to the sauce than good.
The sauce (made from seasoning mix) can be made separated and kept in an airtight container for up to 2 months due to its richness.
Absolutely. All you need to do is omit the cayenne peppers and reduce both the amount of Old Bay and Cajun seasoning by half.
Keep in mind that the new non-spicy flavor is not what the recipe originally aims for; thus it'll taste less amazing like it's supposed to be.
