Ingredients

You only need a handful of fresh ingredients and some pantry staples for this show-stopping Cajun feast! Here’s a quick look at why each component plays a starring role:

• Large Shrimp (shell-on and deveined): Shell-on is key here! It protects the shrimp from overcooking and locks in that beautiful juiciness, soaking up all the spicy, buttery sauce.
• Ears of Corn: Adds a pop of sweetness and classic texture—it’s essential for any true boil experience.
• Baby Potatoes: These little guys are the perfect vehicle for the sauce, becoming beautifully tender and soaking up every drop of garlic butter.
• Smoked Beef Sausage: Brings a hearty, smoky, and salty depth that balances the sweetness of the corn and shrimp.
• Lemon (halved): Used in the boiling water for freshness and then squeezed over the top at the end for that necessary bright, acidic finish.
• Cajun Seasoning: The backbone of the flavor! Use a good-quality blend for that authentic, spicy, savory kick.
• Paprika, Garlic Powder, and Onion Powder: These aromatics boost the overall savory flavor profile, making the sauce deep and complex.
• Cayenne Pepper: Optional, but highly encouraged! This is where you get to control the heat level—a little kick goes a long way.
• Salt and Black Pepper: Basic seasoning to ensure every component’s flavor shines through.

For the Garlic Butter Sauce

• Unsalted Butter: The foundation of the sauce. Use high-quality butter for the best richness and flavor.
• Minced Garlic: We’re talking fresh garlic flavor! Sautéing it gently brings out its fragrant sweetness without burning.
• Cajun Seasoning: A second hit of the seasoning ensures the butter sauce is intensely flavorful.
• Lemon Zest and Lemon Juice: Adds a beautiful brightness and acidity to cut through the richness of the butter. Don’t skip the zest—it holds the most concentrated flavor!
• Chopped Parsley: Provides a beautiful fresh color and herbaceous finish to the dish.

How to Make the Cajun Shrimp Boil in Garlic Butter Sauce

This recipe is incredibly simple and comes together quickly once the boiling starts!

Step 1: Cook the Potatoes

Bring a large pot of heavily salted water to a rolling boil. Add the baby potatoes and let them cook first for about 10–12 minutes, until they are starting to become tender but still hold their shape.

Step 2: Add Corn and Sausage

Toss in the cut corn pieces and continue to boil for another 5–6 minutes. Then, add the sliced smoked beef sausage and cook for 3 minutes just to warm it through and let it release a bit of that smoky flavor into the water.

Step 3: Finish the Boil and Drain

Finally, add the shrimp. They cook super fast! Boil them for just 2–3 minutes, or until they turn pink and opaque. As soon as they are done, immediately drain all the potatoes, corn, sausage, and shrimp and set them aside.

Step 4: Make the Ultimate Garlic Butter Sauce

In a large skillet (you want room to toss!), melt the butter over medium heat. Add the minced fresh garlic and sauté for 1–2 minutes until you can really smell that gorgeous fragrance. Don’t let it burn!

Step 5: Spice it Up

Stir in the Cajun seasoning, paprika, garlic powder, onion powder, cayenne pepper, lemon zest, and lemon juice. Give it a quick whisk until everything is beautifully combined and bubbling. This is where the magic happens!

Step 6: Coat and Serve

Add the drained shrimp, potatoes, corn, and sausage directly into the skillet with the sauce. Use tongs to gently toss everything until it’s perfectly coated in that spicy, buttery goodness. Sprinkle the chopped parsley over the top, give it a final squeeze of fresh lemon, and serve immediately!

Pro Tips for Making the Recipe

• Don’t Overcook the Shrimp! Shrimp goes from perfectly cooked to rubbery in seconds. Once they turn pink and curl into a ‘C’ shape, they’re done. Pull them out immediately.
• Use Fresh Garlic: While we use garlic powder in the seasoning blend, please, please use fresh minced garlic for the butter sauce. It makes all the difference in fragrance and flavor!
• Salt the Water: Like pasta, the boiling water should be heavily salted (like the sea!). This seasons the potatoes and corn right from the start.
• Warm the Plates: Since this is a dish best served piping hot, warm your serving platter or individual bowls before tossing the boil to help keep the feast warm longer.

How to Serve

This is a classic ‘dump’ meal, designed to be served family-style!

• Traditional Style: Lay down some newspaper or parchment paper on your table, dump the entire boil right in the middle, and let everyone dig in! Don’t forget the wet wipes and napkins!
• Pairing Perfection: Serve this with a crisp, simple side salad (the acidity cuts the richness perfectly) or some thick, crusty French bread for soaking up any extra garlic butter sauce.
• Garnish: Always finish with a sprinkle of fresh parsley and a generous squeeze of fresh lemon juice—it lifts all the heavy, rich flavors.

Make Ahead and Storage

Storing Leftovers

If you happen to have any leftovers (it’s rare!), place them in an airtight container in the fridge. They will keep well for up to 3 days.

Freezing

Freezing this dish is generally not recommended. The potatoes can become mealy, and the shrimp’s texture often degrades after freezing and thawing. This is truly best enjoyed fresh!

Reheating

To reheat, the best method is in a large skillet over medium-low heat. Add a tiny splash of water or chicken broth to create steam and prevent the garlic butter from burning, then gently toss everything until warmed through. Alternatively, a quick reheat in the microwave works fine in a pinch.

FAQs

1. Can I add other types of seafood to this boil?

Absolutely! The beauty of a seafood boil is its versatility. You can easily add other quick-cooking seafood like mussels or clams (add them early in the boiling process to ensure they open), or go for a real Southern treat by adding crab legs or crawfish. Just be sure to adjust your cooking times accordingly to ensure everything is perfectly cooked.

2. How can I control the spiciness of the dish?

The heat mainly comes from the Cajun seasoning and the cayenne pepper. To make it milder, use half the amount of cayenne pepper, or skip it entirely, and use a “mild” labeled Cajun seasoning. To really kick up the heat, double the cayenne or add a dash of hot sauce into the garlic butter mixture!

3. Do I have to use shell-on shrimp?

While you can technically use peeled and deveined shrimp, it is highly recommended to stick with shell-on. The shells act as a natural barrier, protecting the delicate shrimp meat and keeping it juicy. More importantly, the shell soaks up all the flavor from the boiling water and the garlic butter sauce, which transfers to the meat as you eat it—pure flavor insurance!

4. What kind of sausage should I use if I don’t want beef?

Smoked sausage is the best choice here because it brings that deep, necessary smoky flavor. If you prefer to avoid beef, look for a high-quality smoked pork sausage, such as Kielbasa or Andouille sausage. Andouille is a classic choice for Cajun dishes and will provide a nice little spicy kick of its own!
