An oven roasted southern shrimp boil brings the messy joy of a low-country spread to a single sheet pan with far less cleanup. You get sweet shrimp, smoky sausage, tender corn, and baby potatoes all coated in a buttery Cajun seasoning and roasted until everything caramelizes at the edges. This method keeps the shrimp from overcooking in boiling water and lets the potatoes and corn pick up real roasted color.
The recipe scales easily for two or a full table, and the seasoning balance leans savory with a mild heat rather than blow-your-head-off spice. You control the salt and the shake of cayenne, so it works for weeknight dinners and relaxed weekend gatherings alike. If you enjoyed this, our roasted lemonade copycat is worth trying next. Making this oven roasted southern shrimp boil at home is surprisingly straightforward once you know the key steps.
Why You’ll Love These Oven Roasted Southern Shrimp Boil
- One sheet pan means you skip the giant pot and the straining mess of a traditional boil.
- Roasting concentrates flavor so the sausage renders and the corn sweetens instead of diluting in water.
- The shrimp stay plump because they roast quickly over the top of the longer-cooking vegetables.
- You can prep the vegetables ahead and just add shrimp before the final roast.
- It reads as a southern shrimp boil but fits a standard home oven and a weeknight clock.
Ingredients You’ll Need
- 1 1/2 pounds large shrimp (21/25 count), peeled and deveined, tails on
- 12 ounces andouille sausage, sliced into 1/2-inch rounds
- 1 pound baby Yukon gold potatoes, halved
- 3 ears fresh corn, each cut into 4 pieces
- 5 tablespoons unsalted butter, melted
- 2 tablespoons Cajun seasoning (low sodium if available)
- 1 tablespoon olive oil
- 4 cloves garlic, minced
- 1 lemon, cut into wedges
- 2 tablespoons fresh parsley, chopped
- 1/2 teaspoon cayenne pepper (optional, for extra heat)
Ingredient Substitutions
Andouille sausage: Replace with an equal weight of smoked kielbasa if andouille is unavailable. Kielbasa is milder and slightly sweeter, so add 1/4 teaspoon extra cayenne to keep the southern shrimp boil edge. The texture stays firm through roasting, but you lose some of the peppery bite that andouille brings to the butter. The oven roasted southern shrimp boil works well for weeknight cooking when time is limited.
Baby Yukon gold potatoes: Use the same weight of red baby potatoes if gold are gone from the bin. Reds hold shape a touch better and have a waxier bite, so they won’t mash under the shrimp weight. Trim roast time by 3 to 4 minutes since red skins are thinner and soften faster at 200°C / 400°F. Storing leftover oven roasted southern shrimp boil correctly keeps it tasting good for days.
Fresh corn: Swap in 2 cups frozen corn kernels when out of season, spread evenly so they roast instead of steam. Frozen corn releases more water, so pat dry first and expect lighter browning on the pan. You also skip the cob sweetness, so a small pinch of sugar in the butter helps balance it. For the best results with this oven roasted southern shrimp boil, read through all the steps before starting.
Unsalted butter: Use 4 tablespoons olive oil plus 1 tablespoon butter for a dairy-light version with less richness. The coating will be thinner and the vegetables brown a little faster, so check the pan 5 minutes early. Flavor shifts from creamy to more herbaceous, which pairs well with extra garlic.

Step-by-Step Instructions
- Heat the oven to 200°C / 400°F and line a large rimmed sheet pan with parchment for easier cleanup.
- Toss the halved baby potatoes with 1 tablespoon olive oil and 1 tablespoon Cajun seasoning in a bowl until coated.
- Spread potatoes cut-side down on the pan and roast at 200°C / 400°F for 20 minutes until the bottoms are golden and a knife slides in with slight resistance.
- Add the corn pieces and andouille slices to the pan, stir gently, and roast another 15 minutes until sausage browns at the edges.
- Whisk melted butter, minced garlic, remaining Cajun seasoning, and optional cayenne in a small bowl.
- Push vegetables and sausage to one side, add shrimp, pour the butter mixture over everything, and toss to coat on the pan.
- Roast 8–10 minutes until shrimp turn opaque pink and curl loosely, with no gray translucency at the center.
- Squeeze lemon wedges over the pan, scatter parsley, and serve immediately while the butter is still glossy.
Pro Tips
Cut the potatoes to a uniform size so they finish in the same window; mixed sizes leave some crunchy and some falling apart. A sheet pan dinner works best when the pan isn’t crowded, so use two pans if the shrimp look stacked.
Roast the potatoes cut-side down first to build a browned base, then flip during the corn step if you want color on both sides. This avoids the pale, steamed look you get from constant stirring.
Pull the shrimp the moment they curl and turn opaque; they keep cooking from pan heat for a minute after removal. Overcooked shrimp tighten into rubber, which no amount of butter fixes.
Dry the shrimp with paper towels before they hit the pan so the butter adheres instead of sliding off. Wet shrimp steam and the Cajun coating won’t stick to the surface.
Common Mistakes to Avoid
Adding shrimp at the start with the potatoes is the most common error; they roast in 8 minutes, not 35, so they end up tough. Keep them out until the vegetables are nearly done, then fold them in for the final stretch.
Skipping the parchment or a lightly oiled pan leads to stuck-on butter and burned corn sugar that’s annoying to scrub. The garlic butter shrimp method also relies on a slick surface for even browning.
Using a low-sodium-free Cajun blend without tasting first can oversalt the dish once butter and sausage join. Mix the seasoning into the butter separately so you can adjust before it touches the food.
Serving Suggestions
Set the pan in the middle of the table and let everyone scoop from it for the full boil experience without the newspaper floor cover. A side of Greek salad cuts the richness with crisp cucumber and tomato.
Offer extra lemon and a bottle of hot sauce so guests tune their own heat at the plate. Crusty bread on the side soaks the leftover butter better than a fork alone.
Storage and Reheating
Cooled leftovers keep in an airtight container in the fridge for up to 3 days and should not sit out longer than 2 hours total. Shrimp and sausage both hold safely when chilled quickly after the meal.
Reheat in a 175°C / 350°F oven for 10 to 12 minutes until the shrimp reach an internal temperature of 60°C / 140°F and the potatoes are hot through. Avoid the microwave if you want the corn to stay firm rather than soggy.
This dish does not freeze well because the shrimp turn mealy once thawed, so plan to finish it fresh or within the fridge window.
Recipe Variations
Low-Country Crab Add
Add 1/2 pound lump crab meat in the final 5 minutes so it warms without breaking apart. The crab picks up butter without needing extra seasoning, and you get a true coastal mix beyond shrimp and sausage.
Sheet Pan Tacos
Spoon the roasted mix into warm tortillas with slaw for a shrimp tacos spin built from the same pan. The corn and potato pieces mash slightly and act like a warm filling against crisp shells.
Extra Smoky Version
Replace half the andouille with smoked turkey sausage and add 1 teaspoon smoked paprika to the butter. The result is deeper and leaner, with a campfire note that suits outdoor-style dinners.
Garlic Heavy Side
Double the garlic and pair the pan with a garlic shrimp pasta on the side for a double-seafood table. The extra garlic in the butter makes the corn taste almost confit-like by the end.
Oven Roasted Southern Shrimp Boil

Ingredients
Instructions
-
Heat oven and prep pan
Heat the oven to 200°C / 400°F and line a large rimmed sheet pan with parchment for easier cleanup. A rimmed pan keeps the butter from running off while the ingredients roast in a single layer.
-
Season and roast potatoes
Toss the halved baby potatoes with 1 tablespoon olive oil and 1 tablespoon Cajun seasoning in a bowl until coated. Spread potatoes cut-side down on the pan and roast at 200°C / 400°F for 20 minutes until the bottoms are golden and a knife slides in with slight resistance.
-
Add corn and sausage
Add the corn pieces and andouille slices to the pan, stir gently, and roast another 15 minutes at 200°C / 400°F. The sausage should brown at the edges and the corn should soften and pick up light color by the end of this step.
-
Mix butter seasoning
Whisk melted butter, minced garlic, remaining Cajun seasoning, and optional cayenne in a small bowl until combined. This garlic butter is what coats the shrimp and vegetables for the final roast.
-
Coat shrimp and vegetables
Push vegetables and sausage to one side, add shrimp, pour the butter mixture over everything, and toss to coat on the pan. Make sure the shrimp are dry from paper towels first so the butter adheres instead of sliding off during roasting.
-
Roast shrimp until done
Roast at 200°C / 400°F for 8–10 minutes until shrimp turn opaque pink and curl loosely, with no gray translucency at the center and an internal temperature of 63°C / 145°F. Pull the pan the moment they curl so they do not overcook from retained pan heat.
-
Finish with lemon parsley
Squeeze lemon wedges over the pan, scatter parsley, and serve immediately while the butter is still glossy. The acid brightens the roasted Cajun coating and the herbs add a fresh note at the table.
