Ingredients

What makes this seafood boil so delicious is the combination of fresh seafood, smoky sausage, colorful vegetables, and a garlic butter sauce that’s packed with Cajun flavor.

For the Seafood Boil

1½ pounds large shrimp, peeled and deveined, tails on
12 ounces smoked beef sausage (pork-free), sliced into thick rounds
1½ pounds baby potatoes
4 ears corn on the cob, cut into thirds
8 ounces sea scallops (optional)
1 lemon, cut into wedges
2 tablespoons Cajun seasoning
1 teaspoon smoked paprika
1 teaspoon garlic powder
½ teaspoon freshly ground black pepper
Salt, to taste
2 tablespoons fresh parsley, chopped

For the Cajun Garlic Butter Sauce

½ cup (1 stick) unsalted butter
6 cloves garlic, finely minced
1 tablespoon olive oil
1 tablespoon Cajun seasoning
1 teaspoon smoked paprika
½ teaspoon crushed red pepper flakes (optional)
1 tablespoon fresh lemon juice
½ cup low-sodium chicken broth
1 tablespoon fresh parsley, chopped

Instructions

Making this flavorful seafood boil is surprisingly simple. The secret is cooking each ingredient just right before bringing everything together in that irresistible garlic butter sauce.

1. Prepare All Your Ingredients

Before turning on the stove, take a few minutes to get everything ready.

Wash the baby potatoes thoroughly, scrubbing away any dirt. You can leave the skins on because they add a lovely texture and help the potatoes hold their shape while cooking.

Cut each ear of corn into three smaller pieces.

Slice the smoked beef sausage into thick, bite-sized rounds. These pieces will brown beautifully in the skillet and add a delicious smoky flavor to the dish.

Make sure the shrimp are peeled and deveined. Leaving the tails on gives them that classic seafood-boil appearance and makes them easy to pick up.

If you’re including scallops, gently pat them dry with paper towels. This helps them develop a beautiful golden crust when seared.

Once everything is prepared, cooking becomes much easier.

2. Boil the Baby Potatoes

Fill a large pot with water and bring it to a rolling boil.

Add a little salt, then carefully place the baby potatoes into the boiling water.

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

You want the potatoes to become tender enough that a fork can slide into them with just a little resistance.

Be careful not to overcook them, since they’ll be tossed in the garlic butter sauce later.

There’s nothing better than a perfectly tender potato that holds its shape while soaking up all those delicious Cajun flavors.

3. Add the Sweet Corn

During the final 5 minutes of cooking the potatoes, add the corn pieces directly to the same pot.

Let them simmer together until the corn becomes tender and bright yellow.

The natural sweetness of the corn is a wonderful contrast to the savory sausage and spicy Cajun seasoning.

Once the potatoes and corn are ready, carefully drain the water.

Transfer everything to a large bowl or tray and set aside.

4. Season the Shrimp and Scallops

Place the cleaned shrimp in a large mixing bowl.

If you’re using scallops, add them as well.

Sprinkle the seafood with Cajun seasoning, smoked paprika, garlic powder, and freshly ground black pepper.

Gently toss everything until the shrimp and scallops are evenly coated.

The Cajun seasoning brings a wonderful combination of warmth, savory spices, and just the right amount of heat.

Meanwhile, the smoked paprika adds a deeper, slightly smoky flavor that pairs beautifully with the beef sausage.

Let the seafood sit briefly while you heat your skillet.

5. Brown the Smoked Beef Sausage

Heat the olive oil in a large skillet over medium-high heat.

Once the oil is hot, add the sliced smoked beef sausage.

Cook for approximately 3–4 minutes, turning occasionally, until the edges develop a lovely golden-brown color.

You’ll notice the sausage releasing its smoky aroma as it sizzles in the pan.

Those browned edges add an extra layer of flavor that makes the finished seafood boil even more delicious.

Once the sausage is lightly browned, remove it from the skillet and set it aside.

6. Cook the Cajun Shrimp

Using the same skillet, add the seasoned shrimp in a single layer.

Try not to overcrowd the pan. If necessary, cook the shrimp in two batches.

Let them cook for approximately 2–3 minutes on each side, depending on their size.

As they cook, the shrimp will turn pink and opaque, with a tender, slightly firm texture.

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

Once they’re cooked through, carefully transfer them to a plate.

Avoid cooking them longer than necessary, since shrimp can become rubbery when overdone.

7. Sear the Scallops (Optional)

If you’re adding sea scallops, now is the perfect time to cook them.

Place the dried scallops in the hot skillet, leaving a little space between each piece.

Let them sear undisturbed for about 2–3 minutes on the first side, then gently turn and cook the other side until golden and cooked through.

Their outside should have a beautiful golden crust while the center remains tender.

Check that they reach 145°F (63°C).

Transfer the cooked scallops to a separate plate and set them aside.

These little bites of seafood add a lovely restaurant-style touch to the finished dish.

8. Make the Cajun Garlic Butter Sauce

Now comes the part that makes this recipe unforgettable.

Reduce the skillet heat to medium-low.

Add the unsalted butter and allow it to melt gently.

Once melted, stir in the finely minced garlic.

Cook for about 1 minute, stirring frequently, until the garlic becomes wonderfully fragrant.

The smell of warm butter and garlic is one of those kitchen aromas that instantly makes everyone hungry.

Be careful not to let the garlic burn, as it can develop a bitter taste.

9. Add the Cajun Spices and Broth

Sprinkle the Cajun seasoning and smoked paprika into the melted garlic butter.

If you enjoy a little extra heat, add the crushed red pepper flakes.

Stir everything together, allowing the spices to warm gently in the butter.

Next, pour in the low-sodium chicken broth and fresh lemon juice.

Stir well, scraping up any flavorful browned bits left in the skillet from cooking the sausage and seafood.

Let the sauce simmer gently for 2–3 minutes.

As it cooks, the garlic, butter, spices, and broth will come together into a fragrant, richly flavored sauce.

The fresh lemon juice adds just enough brightness to balance the buttery richness.

10. Bring Everything Together

Now it’s time to combine all those delicious ingredients.

Add the cooked baby potatoes and sweet corn to the skillet with the Cajun garlic butter sauce.

Gently toss them until they’re coated in the warm, flavorful mixture.

Next, return the browned beef sausage, cooked shrimp, and optional scallops to the skillet.

Carefully stir everything together, making sure the sauce reaches every piece.

The potatoes will soak up some of that delicious garlic butter, while the shrimp and sausage become coated in the rich Cajun spices.

If your skillet isn’t large enough, transfer everything to a large pot or mixing bowl and pour the warm sauce over the top.

11. Let the Flavors Come Together

Keep the heat low and gently warm everything together for another 1–2 minutes.

Stir carefully so the potatoes stay intact and the seafood doesn’t become overcooked.

At this point, the dish should be beautifully fragrant, with golden potatoes, bright corn, pink shrimp, and smoky sausage all glistening in garlic butter.

The combination of colors and textures makes this meal just as appealing to look at as it is to eat.

12. Transfer to a Large Serving Platter

Carefully transfer the seafood boil to a large serving platter, shallow roasting dish, or aluminum tray.

Arrange the potatoes and corn around the edges, then pile the shrimp and sausage toward the center.

If you’ve included scallops, place them on top so their golden surfaces are visible.

Spoon any remaining Cajun garlic butter sauce from the skillet over everything.

Don’t leave that sauce behind! It’s one of the best parts of the entire recipe.

13. Garnish and Serve Warm

Finish the seafood boil with a generous sprinkle of freshly chopped parsley.

Arrange fresh lemon wedges around the platter so everyone can squeeze a little extra juice over their portion.

For an extra burst of flavor, add one final drizzle of warm garlic butter sauce just before serving.

Bring the platter to the table while everything is still warm.

Serve with crusty bread, fluffy steamed rice, or a simple green salad.

And be sure to have plenty of napkins nearby, because this is the kind of delicious, buttery meal that’s meant to be enjoyed!

Presentation: Turn Your Seafood Boil Into a Feast

One of the most wonderful things about a seafood boil is that it’s naturally colorful and inviting.

The bright pink shrimp, golden corn, tender potatoes, and browned sausage create a beautiful combination that looks impressive without much effort.

For a casual family dinner, serve everything on a large platter in the center of the table. Let everyone help themselves to their favorite pieces.

For a special gathering, use a wide aluminum roasting tray or a beautiful rustic serving dish.

Arrange the ingredients in groups so the colors stand out. Place the corn and potatoes around the edges, with the shrimp, sausage, and scallops piled generously in the center.

A sprinkle of fresh green parsley adds the perfect finishing touch.

You can also tuck a few lemon wedges between the ingredients for an extra pop of color.

For an especially appetizing presentation, reserve a few spoonfuls of the warm Cajun garlic butter sauce and drizzle it over the seafood just before bringing it to the table.

That beautiful buttery shine makes the entire platter look even more irresistible.

If you’re serving this dish for guests, consider placing a small bowl of extra garlic butter sauce nearby for dipping.

Helpful Tips for the Best Cajun Seafood Boil

A few simple tricks can make this already delicious recipe even better.

Choose large, fresh shrimp. Large shrimp are easier to handle and hold up beautifully when tossed with the potatoes, corn, and sauce.
Don’t overcook the seafood. Shrimp and scallops cook quickly, so keep an eye on them to maintain their tender texture.
Use smoked beef sausage for extra flavor. Its savory, smoky taste complements the Cajun spices wonderfully.
Keep the potatoes evenly sized. This helps them cook at the same rate and prevents some from becoming too soft.
Use fresh garlic whenever possible. Freshly minced garlic gives the butter sauce a wonderful aroma and richer flavor.
Adjust the Cajun seasoning to your taste. Some blends are saltier or spicier than others, so taste the sauce before adding extra salt.
Don’t skip the lemon juice. Its fresh, bright flavor balances the richness of the butter and brings out the natural sweetness of the seafood.

Easy Ways to Customize Your Seafood Boil

This recipe is wonderfully flexible, making it easy to adjust based on your favorite ingredients.

If you love seafood, add extra scallops or include pieces of cooked crab.

For a milder version, reduce the Cajun seasoning slightly and leave out the crushed red pepper flakes.

If you prefer a spicier seafood boil, add a little extra Cajun seasoning or a pinch more crushed red pepper.

You can also add sliced bell peppers or mushrooms for extra vegetables and color.

And if you enjoy a stronger citrus flavor, finish the dish with a little fresh lemon zest.

Each variation creates a slightly different experience while keeping that delicious garlic butter flavor at the heart of the recipe.
