This Sheet Pan Shrimp Boil has all the flavors of a classic Cajun seafood boil, without the mess or the GIANT pot! Skip the broth and enjoy juicy shrimp, tender potatoes, sweet corn, and smoky sausage all roasted together on one sheet pan in a garlicky Cajun butter. It’s an easy dinner that feels like a Southern feast, without the cleanup after!
Why You’ll Love This Shrimp Boil Bake
I’ll be honest, my hubby loves the flavors of a seafood boil! But setting up a whole boil with the huge pot takes a lot of effort. This sheet pan version captures all the bold flavors of a classic Cajun shrimp boil, without the messy cleanup! Everything roasts right on one sheet pan, from the tender potatoes and sweet corn to the juicy shrimp and smoky sausage, all coated in a garlicky Cajun butter sauce.
And while I can’t actually eat shrimp myself (allergy problems!), I still love making this dish for my shellfish-loving husband because it reminds him of his New England and Alabama roots. It’s requested every summertime. I usually add extra sausage since that’s the first thing to disappear, and I eat more sausage since I can’t eat the shrimp!
What Is a Sheet Pan Shrimp Boil?
If you’ve never heard of a shrimp boil, it is a Southern feast where shrimp, corn, potatoes, and sausage are simmered together in a big pot of seasoned water and served family-style. This sheet pan version takes all those same ingredients and flavors but roasts them in the oven instead, without the need for special equipment. It’s a clever twist on a classic that’s just as fun (and way easier) to serve!

Ingredients You’ll Need for Shrimp Boil Bake
- Baby Potatoes: I like to use baby potatoes here since they cook quickly! You can also use red potatoes, new potatoes, or Yukon Gold potatoes; just cut them into smaller, evenly sized pieces.
- Corn on the Cob: Break the corn into smaller pieces so they cook more quickly, too.
- Red Onion: Slice it into large chunks! It will caramelize in the oven, adding lots of flavor to the bake.
- Smoked Andouille Sausage: For that smoky, classic Cajun flavor!
- Shrimp: Use frozen (thawed) or fresh shrimp. If you use pre-cooked shrimp, it will be overcooked. I’ve used both deveined and peeled and raw shrimp, just use a toothpick near the tail to pull up the vein (shrimp poop ew!) and slowly pull out the vein. Use slightly larger shrimp for this recipe; smaller shrimp may cook too quickly.
- Unsalted Butter: To add some richness to the mix! This will also create enough liquid to keep everything moist. I use unsalted butter; if using salted butter, it may smoke at the high heat.
- Spices: This is where all that Cajun flavor comes from! You will need Old Bay seasoning, garlic powder, smoked paprika, onion powder, black pepper, salt, and some cayenne pepper.
- Lemon: The zest and the juice both add a bright flavor to balance out the bold, spicy flavors.
- Fresh Parsley: To garnish! Try a little cilantro if you prefer!

Cajun Garlic Butter Sauce
This flavorful sauce ties everything together. It’s made with butter, Old Bay, paprika, garlic and onion powder, salt, pepper, and a touch of cayenne for heat.
Fresh Tip! You can swap the spices for 1 tablespoon of your favorite Cajun seasoning mix, but still add the Old Bay and salt for that signature flavor.
How to Parboil Potatoes and Corn (or Skip It!)
Parboiling helps everything roast evenly without overcooking the shrimp. Here’s how:
Add potatoes to cold, salted water. Bring to a boil and cook for 5 minutes. Add corn pieces to the pot and boil both for 5 more minutes. Drain well before roasting.
Want to skip the boiling? Roast potatoes, corn, and sausage first for 30 minutes, then add the shrimp and onion with sauce for the final 8–10 minutes. More details in the recipe card!
How to Make This Cajun Shrimp Boil Bake
Step 1: Prep and Parboil
Boil potatoes and corn briefly, then drain and add to your sheet pan.
Step 2: Make the Sauce
Mix melted butter with seasonings to create a pourable Cajun sauce.
Step 3: Layer and Toss
Add sausage, onion, and shrimp to the pan. Pour the sauce over and toss gently to coat.
Step 4: Bake and Finish
Roast at 400°F for 18–20 minutes, or until the shrimp is pink and the edges are browned. Squeeze lemon juice over the top and garnish with parsley.
💡 Fresh Tips for Shrimp Boil Success
- Give everything some space! If your sheet pan’s feeling crowded, grab a second one. You want those veggies to roast up golden, not steam in a pile. Rotate the pans halfway through cooking.
- Test those taters. Potatoes should be fork-tender before the shrimp joins the party. Underdone spuds = sad dinner.
- Dry your shrimp well. A quick pat with paper towels helps them roast into tender shrimp instead of turning soggy. If frozen, make sure you thaw them in a colander and pat them dry.
- Toss in that buttery goodness while it’s hot. Adding the herb-spice butter while everything’s fresh from the oven helps coat every bite with flavor.
- Save your sanity; line the pan. Use parchment or foil for super easy cleanup. You’ll thank yourself later.
Make Ahead + Storage Tips
💡 Tip: To keep everything moist while reheating (especially shrimp), cover lightly with foil in the oven or add a splash of water before microwaving.
- Storage: Store leftovers (if you actually have any!) in an airtight container in the refrigerator for up to 3 days.
- Oven Reheating: Spread leftovers on a baking sheet and warm at 350°F (175°C) for about 10 minutes, or until heated through.
- Air Fryer Reheating: Heat at 350°F (175°C) for 4–6 minutes, shaking or flipping halfway through.
- Microwave Reheating: Heat on a microwave-safe plate at 50% power for 1–2 minutes, checking and stirring halfway through to avoid overcooking the shrimp.
- Freezing: I don’t recommend freezing, as potatoes don’t freeze well, and the shrimp can get rubbery.
Variations & Substitutions
As with all my recipes, make it yours! Don’t like something, keep it out, LOVE another ingredient, add more…
- Protein Substitutes: Use Kielbasa, Cajun sausage, chicken sausage, or your favorite sausage. In place of the shrimp or in addition, try lobster if available. Of course, crawfish are always a draw!
- Add more spice: Whether you add a few shakes of red pepper flakes, more paprika, garlic, or Italian seasoning, you get the idea! Add some chopped fresh herbs like rosemary, oregano, etc.
- Finish with lime juice in place of lemon juice.
- Use fresh minced garlic cloves in addition to garlic powder. Toss into the veggies.
- Vegetables: While traditional shrimp boil veggies are potatoes and corn, there’s no reason you cannot swap out your favorites, try adding asparagus when you add the shrimp, zucchini, red bell pepper, and others.
Shrimp Boil Leftover Makeover
Leftovers? Try these fun ideas:
- Toss with cooked pasta and a splash of cream for a shrimp boil pasta.
- Pile on top of fluffy rice (or Zatarain’s rice!) or grits for a hearty bowl.
- Add to a salad for a quick lunch!
How to Serve This Cajun Shrimp Boil Bake
This Cajun shrimp boil recipe is perfect to serve right from the sheet pan for a casual, family-style meal! Just top it off with lemon wedges for people to squeeze as they please. For a little extra something, I like to serve it with crusty bread (like my French bread!) to soak up any of those juices. It also goes great with something fresh on the side, like an Italian chopped salad or some apple cabbage slaw!
FAQs
Yes! But you’ll want to thaw them first, and pat them dry. If you need to thaw the shrimp quickly, you can place them in a large bowl of cold water. Every 15 minutes, replace the water with more cold water, and they will be thawed in about an hour. Drain in a colander.
Louisiana shrimp boil is just slightly spicy. You can adjust the spice according to your preference by adding more or less cayenne pepper!
Absolutely! Just double the recipe and then divide it between two sheet pans so everything roasts evenly.
The shrimp should change from translucent to opaque in color, turn pinkish, and form themselves into a “C” shape. If they form an “O” shape, they are most likely overcooked.
The Secret to a Great Cajun Shrimp Boil Bake
It’s all about layering flavor and timing the roast. The butter-spice mix infuses every ingredient, while staggered baking keeps textures just right. It’s your favorite seafood boil; simplified!

Equipment
- usa sheet
Ingredients
- 1 and ½ pounds baby potatoes (gold or red), halve the large ones (24oz, 680g)
- 3-6 ears of corn on the cob approximately 1-1.5 lbs, (450-680g)
- 1 large large red onion cut into large chunks, about (280g)
- 12 ounces smoked andouille sausage sliced 1 inch thick, (340 g) or favorite sausage
- 1 pound raw shrimp deveined (medium to large), (16oz, 454g) (see notes)
- ⅓ cup unsalted butter melted, if using salted, know that it might smoke in the oven (2.65 oz, 75g)
- 1 tablespoon Old Bay seasoning
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- 1 teaspoon onion powder
- ½ teaspoon black pepper
- ½ teaspoon salt
- ¼ – ½ teaspoon cayenne pepper
- 1 lemon zested, then squeezed as a finish.
- chopped curly or Italian parsley for garnish
Instructions
- Line a large sheet pan with parchment paper or aluminum foil. Preheat your oven to 400°F (205°C).
- Wash and prep the potatoes. Leave baby potatoes whole if small, or cut larger ones in half for even cooking. Place potatoes in a large pot and cover with cold, salted water.Bring to a boil over medium-high heat. Once boiling, cook the potatoes for 5 minutes.1 and ½ pounds baby potatoes
- Break corn into 3–4 pieces per ear, then add to the pot with the potatoes.3-6 ears of corn on the cob
- Continue boiling both for another 5 minutes; the potatoes should be just fork-tender and the corn slightly softened but still firm.
- Drain well, then transfer to your sheet pan to toss with the other ingredients and bake.
- While the potatoes are cooking, in a small mixing bowl, combine the melted butter with the Old Bay seasoning, paprika, onion powder, pepper, salt, lemon zest, and cayenne pepper. You'll end up with a thick sauce that's pourable but still thick.⅓ cup unsalted butter, 1 tablespoon Old Bay seasoning, 1 teaspoon garlic powder, 1 teaspoon smoked paprika, 1 teaspoon onion powder, ½ teaspoon black pepper, ½ teaspoon salt, ¼ – ½ teaspoon cayenne pepper, 1 lemon
- Add the sausage and red onion to the sheet pan. Remove one tablespoon of spice butter mixture, then drizzle the rest over the sheet pan with potatoes, corn, etc. Tossing to coat.1 large large red onion, 12 ounces smoked andouille sausage
- Bake in a preheated oven for 12-15 minutes.
- In a bowl, toss the shrimp with the reserved sauce and place them on top, baking an additional 8-10 minutes until pink and opaque. Once potatoes are fork-tender, add the shrimp. My hubby prefers the shells left on (deveined) as it helps hold the moisture in while cooking, also giving the shrimp more flavor.
- Remove from the oven and squeeze the juice from one lemon over the top of the boil. Sprinkle with parsley and serve immediately with plenty of napkins and extra butter for the corn.
Notes
- Parboil potatoes and corn so they cook evenly with the shrimp. Overcooked shrimp turns rubbery, unless you’re using the longer oven-only method (below).
- Keep everything in an even layer, without overcrowding the pan.
- This dish has a mild kick. For more heat, add ¼–½ teaspoon extra cayenne or a few red pepper flakes. Sensitive to spice? Skip the cayenne, it’ll still be packed with flavor!
- Using Cajun seasoning? Skip the individual spices and use 1 tablespoon of your blend, plus Old Bay and salt for that classic flavor boost.
- Shrimp: To peel or not to peel? My hubby prefers the flavors and juiciness of the shrimp when baked with the shell on, so I don’t typically peel them. But I do devein them. I “marinate” them while the rest is baking in the butter sauce; the sauce still permeates, giving great flavor, and the shells actually keep moisture and flavor in! But feel free to use peeled and deveined shrimp.
- Use your favorite proteins: Any thick sausage will work, try lobster, crawfish, etc.
- Vegetables: Feel free to swap in your favorite veggies, too!
- Preheat oven to 400°F (205°C).
- In a large bowl, combine: Baby potatoes (cut in half or quarters if large), Corn (broken into chunks), Sausage slices (1-inch thick), and chunked red onion.
- Reserve 1 tablespoon of butter, spice mixture, then drizzle with the butter-spice sauce (keep the rest for the shrimp).
- Toss to coat and spread on a parchment– or foil-lined sheet pan in a single layer.
- Bake for 25-30 minutes, tossing the potatoes once halfway through, until they are fork-tender.
- Add shrimp, onion, and remaining sauce:
- In a bowl, toss the raw shrimp with the remaining butter-spice sauce on top.
- Toss everything gently to coat, spreading evenly on the pan.
- Return to oven and bake 8–10 more minutes, until shrimp is pink, opaque, and just curled into a “C”.
