What Is a Sheet Pan Seafood Boil?

A traditional seafood boil (also called a low-country boil, Frogmore stew, or shrimp boil) is a Southern and Gulf Coast tradition where seafood, sausage, corn, and potatoes are cooked together in a large pot of seasoned water and then dumped onto a paper-covered table for everyone to eat communally.

A sheet pan seafood boil delivers all of those same flavors by roasting everything together in the oven. Roasting actually gives you a few adbantages; the potatoes develop a slightly crispy edge, the sausage gets a little carmaelized, and there’s no draining or lugging a heavy pot. It is a practical approach to a beloved tradition. While this is usually a summer meal, making it in the oven makes this an every-season recipe.

Ingredients for a Spicy Sheet Pan Seafood Bake

The Main Ingredients

This recipe is flexible by design. Here is what I use as a starting point:

• Jumbo shrimp (shell-on for the best flavor)
• Andouille sausage, sliced into rounds
• Small red potatoes, halved
• Ears of sweet corn, cut into 2-3 inch pieces

The Cajun Butter Sauce

The sauce is what makes this dish. Make the butter sauce and divide it into thirds: one for the potatoes, one for the corn, and one for the seafood and sausage. Add a squeeze of fresh lemon juice (about 1/4 cup) to the seafood portion for a bright finishing note.

Ingredient Substitutions or Add-Ins

One of the best things about a seafood boil is how adaptable it is. Try any of these swaps or additions.

• Seafood alternatives: mussels, clams, crawfish, snow crab legs, lobster tails, or soft shell crab
• Sausage alternatives: kielbasa or chorizo (go for a smoky variety to stay true to the low-country boil flavor profile)
• Vegetable alternatives: quartered onions, sweet potatoes, zucchini slices, or tomatoes

How to Make a Sheet Pan Seafood Boil in the Oven

Step 1: Prep Your Ingredients

Halve the potatoes, Cut the corn into 2-3 inch pieces. Slice the sausage into rounds. If your shrimp are shell-on, leave them that way for the best flavor (you can peel them before cooking if you prefer a neater presentation). I, personally, think the process of peeling the shells off the shrimp is part of the fun of the meal.

Step 2: Optional – Parboil the Potatoes to Save Time

Potatoes take the longest to cook. To cut the total baking time, bring a large pot of water to a boil, add some salt, and parboil the halved potatoes for about 10 minutes before they go on the sheet pan. This step is optional but recommended if you want to get dinner on the table faster.

Step 3: Build the Sheet Pan

Preheat your oven to 400°F. Line a large rimmed baking sheet with foil or parchment paper and drizzle with about 2 tablespoons of olive oil.

Divide your Cajun butter sauce into thirds:

• Toss the potatoes with the first third and spread in a single layer on the prepared baking sheet.
• Bake the potatoes for 20 minutes (or 10 minutes if parboiled).
• Toss the corn with the second third of the sauce. Add to the pan and bake for 15 more minutes.
• Toss the shrimp and sausage with the remaining third of the sauce plus the lemon juice. Add to the pan and bake for a final 12-15 minutes, until the shrimp are pink and opaque. Garnish with sliced green onions and chopped parsley.

Step 4: Serve It Seafood-Boil Style

Slide the whole pan onto the center of the table or dump everything onto a paper covered surface for the full experience. Set out extra lemon wedges, hot sauce and some rolls of paper towels.

Get Recipe Ingredients

Instructions

• Preheat Oven to 450°

Ingredient Prep

• Break the corn into 2-3 inch pieces. I found it hard to break, so if you decide to cut it, be careful.
• Cut the sausage into 1/4" slices
• Wash and then quarter or halve the potatoes, depending on the size (keep the skin on the potatoes).
• Wash the shrimp (seafood). I didn't take the shells off but you can.
• Chop the green onions and finely chop the parsley

Butter Sauce

• Melt the stick of butter in a microwave-safe bowl in the microwave for about 1 minute.
• Combine the butter with the spices

Prepare & Assemble

• Line a baking sheet with aluminum foil
• Drizzle about 2 tablespoons of olive oil onto the foil. I used my clean hands to spread it around but you can also use a pastry brush or the back of a wooden spoon.
• Mix potatoes with 1/3 of the butter mixture. I did it in a bowl but you can also do it right on the baking sheet, being careful not to rip the foil. Make sure the potatoes are in a single layer
• Put in preheated oven for 30 minutes, turning 1/2 way through
• After 30 minutes, add the corn with another 1/3 of the butter mixture. Combine with potatoes and put back into the oven for 15 minutes. Again, make sure it's in a single layer.
• Add the last 1/3 of the butter to the shrimp and the sausage, and stir in with the juice of 1/2 a lemon.
• Lastly add the shrimp and sausage mixture to the pan, stirring well, making sure it's still a single layer and put back into the oven for the last 15 minutes
• I prepped all of my ingredients in three different bowls all at once when the butter was still melted. It made a little more mess but worked better for me.
• Garnish with parsley, green onions and lemon wedges

Tips for the Best Sheet Pan Seafood Bake

• Use a large rimmed baking sheet so ingredients roast in a single layer
• Don’t rush the potatoes. They need the most time. Parboiling is your friend.
• Shell-on shrimp stay juicier and add to the hands-on, festive feeling of the meal.
• Taste your Cajun butter sauce before dividing and adjust the heat to your preference. A little more cayenne goes a long way.
• Always line your pan with foil or parchment paper for the easiest cleanup

Storage and Make-Ahead Tips

Leftovers: Store in an airtight container in the refrigerator for up to 2 days. Reheat in a 350 °F oven, in a skillet over medium heat, or pop in the microwave for a few minutes. Shrimp can be rubbery if overheated, so warm gently.

Make-ahead tip: You can measure out all of your spices into a small bowl the day before. Parboil the potatoes, cut up your sausage, and cut up your corn a day ahead of time, and store them in the refrigerator until you are ready to prepare your pan.

The seafood boil is a time-honored tradition in many coastal regions of the country. Celebrating the warmer seasons and a bountiful catch—in perfect fashion—bringing communities (small and large) together in a social soirée of epic proportions.

What to Serve with a Seafood Boil

The seafood, sausage, corn, and potatoes are a full meal on their own, but a few simple additions round this meal out nicely:

• Crusty French or sourdough bread to soak up the Cajun butter
• A simple green salad
• Dirty Rice
• Ice-cold beer or crisp rosé wine

A Sheet Pan Seafood Bake is the Perfect Party Dinner

This recipe makes a generous amount of food, which is exactly the point. It scales easily: just double it and use a second sheet pan if you have a bigger crowd. The no-fuss, hands-on style of eating creates an instant party atmosphere, whether you are hosting a backyard summer dinner, a game night, or a cozy gathering in the middle of winter.

The low-country boil tradition is rooted in community. Coastal families have been spreading newspaper on long tables and dumping out steaming pots of seafood for generations. This oven version keeps the spirit alive in any kitchen, any time of year.

FAQ’s

Can I use frozen shrimp?

Absolutely! Just thaw them completely and pat them dry before tossing with the butter sauce. Excess moisture can prevent browning.

How spicy is this recipe?

The heat level is entirely up to you. Start with the Cajun seasoning blend and add cayenne or red pepper flakes to increase the heat. If you are serving kids or guests who prefer mild food, I wouldn’t mess with the original recipe. Offer hot sauce at the table for guests to add at their discretion.

Can I make this on the grill instead?

Absolutely. Place the sheet pan directly on the grill grates over medium heat, or use a disposable foil. Follow the same timing and keep the grill lid closed.

What is the difference between a seafood boil and a seafood bake?

A traditional seafood boil cooks everything in a large seasoned pot of water, then drains it and dumps it out. A seafood bake (also called a sheet pan seafood boil) roasts everything in the oven. The oven method concentrates the flavors, develops a little crispiness on the potatoes and sausage, and has the added benefit of a yummy butter sauce.
