Hands down the best seafood garlic butter sauce I’ve made and tried! I wish I had a picture of it but it looked so good that I instantly had to dig in! Will definitely be using again when I’m in the mood for snow crab legs which is usually once a month! A must try for all my seafood lovers out there!

The best seafood to use for a Cajun seafood boil recipe:

Some of the most popular seafood used in a Louisiana seafood boil recipe are crab legs, crawfish (or crawdads), shrimp, and clams. Almost any kind of shellfish will work though. You can even add some lobster tails to make it super fancy!

Crab legs are just as amazing as crawfish, (and in my opinion, better)! This post isn't to debate that theory though. One of the best parts about seafood is that it takes on the flavors of spices that are used. 

Collect ingredients for the Seafood Boil:

Collect all of the items you need before you get started. It makes cooking so much easier! Here is what you will need for this seafood Cajun boil recipe:

• Seafood: crab legs, shrimp, and any other seafood you like including lobster, clams, or crawfish.
• Sausage: feel free to omit this ingredient if you are not a fan. Beef sausage was used for this recipe. Some of my audience have used chicken sausage, andouille sausage, and even meatless sausage as a substitute.
• Potatoes: red potatoes are best because they hold-up and do not get so mushy. Regular (russet) potatoes can be used if that's what you have. Just cut the boil/cooking time a bit because they will get mushy.
• Corn on the cob: frozen works just fine. Fresh corn on the cob can be used as well. Although you do not have to, you can cut it in half for more servings.
• Optional additions: boiled eggs- don't knock-it until you try it! Some people have sent me pictures of broccoli, and other veggies that they have added. I love it, get creative and make what you like!

Seasonings for seafood boil sauce:

When you first look at the recipe, it does seem like A LOT of seasoning! In reality, it is- but it is not salty seasonings. The majority are just herbs, spices, and Cajun seasoning, with no salt content.

Here are the main spices you will need:

• Garlic powder
• Oregano
• Onion Powder
• Chili powder

All of these seasonings and spices are blended perfectly into the recipe for Cajun crab boil butter sauce. The best butter to drizzle over the crab boil. You should also save some seafood boil sauce to dip your seafood into!

Can I use an oven steamer bag for a seafood bake?

Yes! In fact, I have made my seafood boil this way a few times and it is AMAZING! Make sure you buy the plastic bags that are made for the oven.

Cook the sauce as directed in the recipe card below. Reserve a bit of sauce for dipping if you'd like. Add the seafood and the vegetables to the bag and pour the sauce all over the top.

Then you will bake the seafood for about 20 minutes or so. It is important to keep an eye on the crab and shrimp so that they do not overcook.

Tips for the perfect seafood broil:

• The potatoes take longer to cook, so start cooking them first. Red potatoes are best because they do not get too mushy.
• Shrimp will cook SUPER fast! Use the biggest shrimp you can find; such as colossal shrimp or jumbo shrimp.
• You can use shell-on shrimp or you can buy or peel your shrimp, they both taste amazing.
• This seafood bowl recipe calls for crab legs and shrimp, but you can add or take away any shellfish you would like.
• Some of the best recipe for seafood boil include boiled eggs! You should definitely give it a try.

Different cooking methods for crab and shrimp boil:

All of these photos are a bit different because we make a crab boil A LOT around here. Seafood boil is just a general term for this dish, but the cooking method can vary.

You can have a seafood bake, by adding your shellfish of choice to a baking dish and baking it. A seafood broil can be achieved by adding pre-cooked crab legs and shrimp to a baking dish and broiling it in the oven.

Another great way to enjoy your Cajun crab boil is by adding your seafood to an oven bag and baking it. Add your sauce over the seafood, and bake until it is done.

NOTE: the green stuff you see on top in some of the photos are Parsley Flakes.

Can I use frozen seafood for the crab boil?

Yes! Most of the time, I purchase frozen shrimp and crab legs. Sometimes- it's cheaper, or just easier to find. Most frozen seafood is fully cooked, and then frozen.

Keep that in mind and adjust cooking times accordingly. If it is pre-cooked, cut the cooking time by 5-10 minutes. Try to get the jumbo shrimp w/ shell on if you're buying frozen. It tends to stay juicy and plump!

How long to boil seafood:

Keep in mind the various type of seafood you will be adding to your low country boil. They will all cook at different speeds.

• Crab legs: boil for about 8-10 minutes for crab, 20 minutes for fresh crab clusters
• Shrimp: boil for about 3-5 minutes
• Sausage: boil for 8-10 minutes

Remember to boil your potatoes first, then add your corn before adding the seafood.

How to make the crab boil sauce recipe:

This Garlic Butter Seafood Boil Sauce is the absolute best! Make it super spicy, or not so spicy by adjusting your cayenne and red pepper flakes.

You MUST add the garlic cloves and the Old Bay seasoning though, it gives it that amazing tangy flavor that pairs beautifully with your seafood.

You will need a large stockpot to cook your Cajun seafood boil in. Trust me, you haven't experienced seafood until you add this sauce!

There nothing like cracking that shell open in the right spot and pulling out the WHOLE, juicy piece of crab meat. Then when you add in your corn-on-the-cob, sausage, and shrimp, it is a whole meal!

What to serve with a low country boil:

Although this is a complete meal in and of itself, you can add some side dishes to round out your Cajun boil. Here are a few ideas:

• Garlic bread
• A side salad
• Some roasted vegetables
• Coleslaw

A lot of people like to use their bread to sop up that delicious juicy crab sauce. Adding a side of vegetables will also help balance out the meal!

Now that my mouth is watering.... enjoy this delicious seafood boil recipe!

Instructions

SEAFOOD BOIL

2. Place the corn and red potatoes into the seasoned water. Boil for 10 minutes.
3. Add the crab legs and sausage . Cover with a lid and boil for an additional 15 minutes.
4. Add the shrimp. Boil for 5 minutes (shrimp will turn pink, do not overcook).
5. Drain the water and remove bay leaves. Transfer to serving dish or leave in the stock pot.
6. Pour that delicious garlic butter sauce all over, and/or reserve some sauce on the side to dip the seafood in (recipe below).

GARLIC BUTTER SAUCE

1. Melt one stick of butter and olive oil in a skillet on medium heat. Add onions and sauté until they become translucent.
2. Add Garlic and saute for 30 seconds, stirring constantly so garlic doesn't burn. Add juice of the lemon, and all the seasonings. Adjust cayenne and red pepper to your level of spiciness.
3. Add remaining 3 sticks of butter. Simmer until butter is melted, stir constantly.
4. If using chicken broth, gently stir it into the mixture now. Pour over your favorite seafood and/or reserve some for dipping.
5. Enjoy!

Notes

Chicken broth is used to "cut" the sauce. It does not take away from the flavor in any way. In fact- it's great to add broth if trying to create more sauce, or pour directly over your seafood boil.

Sauce can also be used for dipping.
