Ingredients

This recipe combines fresh seafood, smoky sausage, tender vegetables, and a flavorful homemade Cajun garlic butter sauce.

For the Seafood Boil

1½ pounds (680 g) large shrimp, peeled and deveined, tails on
1 pound (450 g) sea scallops
12 oz (340 g) smoked beef sausage, sliced into thick rounds
1½ pounds (680 g) baby red potatoes
4 ears of corn, cut into thirds
1 medium onion, quartered
1 lemon, halved
2 tablespoons Cajun seasoning
1 tablespoon Old Bay seasoning
1 teaspoon smoked paprika
1 teaspoon garlic powder
½ teaspoon black pepper
Salt to taste
Water or seafood broth, enough for boiling

For the Cajun Garlic Butter Sauce

½ cup (115 g) unsalted butter
6 cloves garlic, minced
1 tablespoon olive oil
1 tablespoon Cajun seasoning
1 teaspoon smoked paprika
½ teaspoon red pepper flakes (optional)
1 tablespoon fresh lemon juice
½ cup seafood broth or reserved cooking liquid
1 tablespoon honey (optional)
2 tablespoons fresh parsley, chopped

For Garnish

Freshly chopped parsley
Lemon wedges
Extra Cajun seasoning (optional)

A little kitchen tip: Fresh shrimp and scallops give this seafood boil a wonderful texture, but properly thawed frozen seafood works beautifully, too. Just make sure to drain it well before cooking so the seafood stays tender rather than watery.

Instructions

Step 1: Prepare All the Ingredients

Before you start cooking, take a few minutes to get everything ready.

Rinse the baby red potatoes thoroughly, cutting any larger ones in half so they cook evenly.

Cut each ear of corn into three smaller pieces, making them easier to handle and serve.

Slice the smoked beef sausage into thick rounds, and make sure the shrimp are peeled and deveined.

If you’re using frozen shrimp or scallops, thaw them completely before cooking.

Having everything prepared ahead of time makes the cooking process much smoother, especially since the seafood cooks quickly at the end.

Step 2: Create the Flavorful Cajun Boiling Broth

Fill a large stockpot about halfway with water or seafood broth.

Add the quartered onion, lemon halves, Cajun seasoning, Old Bay seasoning, smoked paprika, garlic powder, and black pepper.

Bring the mixture to a rolling boil over high heat.

As the liquid heats up, the citrus, garlic, and spices begin releasing their wonderful aromas. The broth becomes fragrant and flavorful, creating the perfect base for cooking the potatoes, corn, sausage, and seafood.

Taste the broth carefully and add salt only if needed, since Cajun and Old Bay seasonings can already contain plenty of sodium.

Step 3: Cook the Baby Potatoes

Once the seasoned broth is boiling, carefully add the baby red potatoes.

Let them cook for approximately 12–15 minutes, depending on their size.

You want the potatoes to begin softening but still hold their shape because they’ll continue cooking as the other ingredients are added.

To check, pierce one with a fork. It should offer a little resistance without feeling completely hard.

The potatoes will slowly absorb the savory seasonings, making them flavorful all the way through.

Step 4: Add the Sweet Corn

Next, add the corn pieces directly to the pot with the potatoes.

Continue boiling for another 5–7 minutes, until the corn becomes tender and bright yellow.

The natural sweetness of the corn is a wonderful contrast to the smoky Cajun spices.

As it cooks, the corn also absorbs some of the flavorful broth, making each bite extra delicious.

Step 5: Warm the Smoked Beef Sausage

Stir the sliced smoked beef sausage into the pot.

Let it simmer for about 3–4 minutes, or until thoroughly heated.

The sausage releases a delicious smoky aroma that adds another layer of flavor to the broth.

By now, the kitchen should smell amazing, with the combination of warm spices, lemon, and savory sausage filling the air.

Step 6: Gently Cook the Shrimp and Scallops

Now it’s time to add the seafood.

Reduce the heat slightly so the broth is simmering gently rather than boiling aggressively.

Carefully add the shrimp and scallops to the pot.

Cook for approximately 3–4 minutes, depending on the size of the seafood, until the shrimp turn pink and opaque and the scallops become opaque and firm.

For food safety, shrimp and scallops should reach an internal temperature of 145°F (63°C).

Be careful not to overcook them. Seafood cooks quickly, and leaving it in the hot broth for too long can make it rubbery.

The goal is beautifully tender shrimp and delicate scallops that remain juicy and flavorful.

Step 7: Drain and Arrange the Seafood Boil

Before draining the pot, carefully reserve about ½ cup of the seasoned cooking liquid.

This flavorful broth will be used in the garlic butter sauce, so don’t forget to save it!

Drain the remaining liquid from the pot.

Transfer the cooked shrimp, scallops, sausage, potatoes, and corn to a large serving tray, roasting pan, or heat-safe platter.

Spread everything out gently, allowing the colorful ingredients to mix naturally.

The bright corn, golden potatoes, pink shrimp, and smoky sausage already create a beautiful presentation.

But the best part is still coming—the garlic butter sauce!

Step 8: Melt the Butter and Sauté the Garlic

In a large saucepan, melt the unsalted butter together with the olive oil over medium heat.

Once the butter is melted and gently bubbling, add the minced garlic.

Sauté for about 1 minute, stirring frequently.

You’ll immediately notice the rich, inviting aroma of garlic blending with warm butter.

Avoid letting the garlic turn dark brown, as it can become bitter.

Step 9: Add the Cajun Spices

Stir the Cajun seasoning, smoked paprika, and optional red pepper flakes into the garlic butter.

Cook for about 30 seconds, stirring continuously.

This quick step helps release the flavors and aromas of the spices, giving the sauce its beautiful reddish-golden color.

The combination of smoky paprika and bold Cajun seasoning creates a warm, savory flavor that pairs perfectly with seafood.

If you prefer a milder sauce, skip the red pepper flakes or use a little less Cajun seasoning.

Step 10: Finish the Rich Garlic Butter Sauce

Slowly pour the reserved seafood cooking liquid into the saucepan.

Add the fresh lemon juice and optional honey.

Stir gently until everything is well combined.

Allow the sauce to simmer for 2–3 minutes until slightly reduced and fragrant.

The lemon juice adds a refreshing brightness, while the honey provides a subtle sweetness that balances the spices.

The reserved cooking liquid brings all the delicious flavors from the seafood boil into the butter sauce, making it even more flavorful.

Finally, stir in the freshly chopped parsley.

The finished sauce should be rich, buttery, fragrant, and full of Cajun flavor.

Step 11: Coat Everything in Garlic Butter

Pour the warm Cajun garlic butter sauce over the cooked seafood, sausage, corn, and potatoes.

Using a large spoon or spatula, toss everything gently until each ingredient is generously coated.

Take care when mixing the scallops, as they’re delicate and can break apart if handled too roughly.

The sauce should cling beautifully to the shrimp, settle into the corn kernels, and coat the potatoes in a glossy layer of seasoned butter.

At this point, the entire dish should look irresistibly delicious.

Step 12: Garnish and Serve

Transfer the seafood boil to a large serving platter if you haven’t already.

Sprinkle freshly chopped parsley over the top.

Arrange a few lemon wedges around the edges, allowing everyone to squeeze fresh lemon juice over their portion.

For those who enjoy extra heat, offer a little Cajun seasoning on the side.

Drizzle any remaining garlic butter sauce over everything just before serving.

Bring the platter to the table while the seafood is still warm, and enjoy!

Presentation and Serving Ideas

One of the most enjoyable things about a seafood boil is its relaxed, family-style presentation.

Unlike meals that require carefully arranged individual plates, a seafood boil is meant to be shared. A big platter of colorful seafood, corn, sausage, and potatoes creates a welcoming centerpiece that encourages everyone to gather around.

For a traditional-inspired presentation, spread everything across a large serving tray or a food-safe, lined table setup.

Arrange the corn and potatoes around the edges, with the shrimp, scallops, and sausage piled in the center.

Pour a little extra garlic butter sauce over the top, allowing it to settle naturally around the ingredients.

Finish with fresh parsley and bright lemon wedges for a beautiful contrast against the golden butter sauce.

Delicious Side Dishes to Serve Alongside

Warm garlic bread: Perfect for soaking up every drop of the flavorful Cajun butter sauce.
Fluffy white rice: A comforting addition that balances the rich, spicy flavors.
Coleslaw: A crisp, refreshing side that complements the smoky seafood and sausage.
Fresh green salad: A lighter option that adds freshness to the meal.
Buttery dinner rolls: Soft bread makes an excellent addition to a family-style seafood feast.
Grilled vegetables: Adds extra color, texture, and smoky flavor to the table.

For a special gathering, serve the seafood boil with small bowls of extra garlic butter sauce so everyone can add as much as they like.

And don’t forget plenty of napkins—this is one of those wonderfully messy meals that’s meant to be enjoyed!

Helpful Tips for the Best Cajun Garlic Butter Seafood Boil

Use fresh, good-quality seafood. Shrimp and scallops are the stars of this dish, so choosing good-quality ingredients makes a noticeable difference.

Cook the ingredients in stages. Potatoes take longer to cook than corn, sausage, and seafood. Adding everything in the correct order helps prevent overcooking.

Don’t overcook the shrimp and scallops. Seafood cooks very quickly and can become tough if left in boiling water for too long.

Save some cooking liquid. The seasoned broth is packed with flavor and makes a wonderful addition to the garlic butter sauce.

Adjust the heat to your preference. Cajun seasoning varies in spiciness, so start with a moderate amount and add more if needed.

Use unsalted butter. This gives you better control over the saltiness of the sauce, especially since the seasonings and sausage may already contain salt.

Add fresh lemon juice. Lemon helps brighten the rich butter sauce and complements the sweetness of the seafood.

Serve immediately. Seafood boils taste best when the ingredients are freshly cooked and the garlic butter sauce is warm.

Store leftovers safely. Refrigerate leftovers in covered containers within two hours. For best quality, enjoy leftover cooked seafood within 3–4 days, reheating thoroughly.
