Simple Shrimp Boil with Garlic Butter Sauce

There’s something about a shrimp boil that makes any day feel like a celebration. Maybe it’s the way everyone gathers around the table, or how you dump everything right onto butcher paper and dig in with your hands. Whatever it is, I’m here for it.

The best part? It’s actually way easier than it looks. You’re basically throwing everything into one big pot and letting it do its thing. No fancy techniques, no complicated steps. Just layers of flavor building up while you’re hanging out with a drink in your hand.

And that garlic butter sauce? It takes the whole thing over the top. I like to make extra because everyone will want to dip their potatoes, corn, and even their bread into it. Trust me, you’ll be glad you did.

What Kind of Shrimp Should I Use?

For a shrimp boil, you’ll want to use large or jumbo shrimp since they hold up better during boiling and are easier to peel. You can buy them either fresh or frozen – just make sure they’re deveined to save yourself some prep time. I usually go for shell-on shrimp because the shells add extra flavor to the boil, plus they’re fun to peel at the table when you’re eating with friends and family. If you’re using frozen shrimp, just thaw them in the fridge overnight or run them under cold water for a quick thaw before cooking.

Options for Substitutions

This shrimp boil is pretty forgiving, so here are some swaps you can make if needed:

• Shrimp: You can use frozen shrimp instead of fresh – just thaw them completely before cooking. If you’re not a shrimp fan, try crawfish or crab legs for a different seafood twist.
• Kielbasa: Andouille sausage is a great swap here and adds a bit more spice. You could also use smoked sausage or even chorizo if that’s what you have on hand.
• Potatoes: Any waxy potato works well – red potatoes, fingerlings, or baby potatoes are all good choices. Just avoid russets as they’ll fall apart too easily.
• Cajun seasoning: If you don’t have Cajun seasoning, make your own by mixing paprika, garlic powder, onion powder, cayenne pepper, and black pepper. Old Bay can also work in a pinch since you already have it in the recipe.
• Butter: Two sticks is traditional for that rich garlic butter sauce, but you can cut it down to 1 stick if you want a lighter version. Just know the sauce won’t be quite as indulgent.
• Corn: Fresh corn on the cob is best, but if it’s not in season, frozen corn on the cob works too. Just add it at the same time as you would fresh.

Watch Out for These Mistakes While Cooking

The biggest mistake people make with shrimp boils is overcooking the shrimp, which turns them rubbery and tough – since shrimp only need 3-4 minutes to cook through, add them at the very end and remove the pot from heat as soon as they turn pink and curl into a C-shape.

Another common error is adding all the ingredients at once, but potatoes and corn need a head start since they take longer to cook, so give them those 5-8 minutes before tossing in the quick-cooking items.

Don’t forget to cut your potatoes into similar-sized pieces (about 2 inches) so they cook evenly, and if you’re using frozen shrimp, make sure they’re completely thawed and patted dry before adding them to the boil.

Finally, many people skimp on seasoning the boiling water itself – treat it like pasta water and make it salty enough that you can taste it, which helps flavor everything from the inside out.

What to Serve With Shrimp Boil?

A shrimp boil is pretty much a complete meal on its own since you’ve got your protein, veggies, and potatoes all in one pot, but I always like to add some crusty French bread or dinner rolls on the side for soaking up that amazing garlic butter sauce. A simple coleslaw with a tangy vinegar-based dressing is a great addition too, since it cuts through the richness of the butter and adds a nice crunch. If you want to round things out even more, try serving it with a light cucumber salad or some extra lemon wedges for squeezing over everything. Don’t forget to put out plenty of napkins and maybe some wet wipes – shrimp boils are meant to be messy and fun!

Storage Instructions

Store: Leftover shrimp boil keeps well in the fridge for up to 3 days. Just pop everything in an airtight container, and store the garlic butter sauce separately if you have any left. The shrimp tastes best when eaten within a day or two, but the potatoes, corn, and sausage hold up great for longer.

Reheat: To warm up your leftovers, I like to spread everything on a baking sheet and heat it in a 350°F oven for about 10-15 minutes. You can also reheat portions in the microwave, but just be careful not to overcook the shrimp or it’ll get rubbery. Drizzle with extra garlic butter sauce when serving for the best flavor.

• Calories: 3100-3500
• Protein: 120-140 g
• Fat: 180-200 g
• Carbohydrates: 220-250 g

Ingredients

For the boil:

• 1.5 lbs potatoes (I use Yukon Gold cut into 1-inch chunks to ensure they cook evenly)
• 4 ears corn (cut into 3-inch rounds for easier serving)
• 1 lb kielbasa (sliced into 1/2-inch thick coins)
• 1.25 lbs shrimp
• 1 large onion
• 1 garlic bulb (sliced horizontally across the top to expose the cloves)
• 1 lemon
• 1/4 cup cajun seasoning (I prefer Slap Ya Mama for a nice kick)
• salt
• 2 tablespoons old bay seasoning
• 1/4 cup fresh parsley, chopped

For the garlic butter sauce:

• 8 oz unsalted butter (I like Kerrygold for a richer, creamier sauce)
• 8 cloves garlic (finely minced for maximum infusion)
• 3 sprigs fresh thyme
• 1/2 lemon

Step 1: Prepare Mise en Place and Infuse Garlic Butter

• 1.5 lbs potatoes, cut into 1-inch chunks
• 1 lb kielbasa, sliced into 1/2-inch coins
• 4 ears corn, cut into 3-inch rounds
• 1.25 lbs shrimp
• 8 cloves garlic, finely minced
• 1/4 cup fresh parsley, chopped
• 1/2 lemon
• 8 oz unsalted butter
• 3 sprigs fresh thyme

Start by preparing all your ingredients: cut potatoes into 1-inch chunks, slice kielbasa into 1/2-inch coins, cut corn into 3-inch rounds, mince 8 cloves of garlic finely, chop parsley, and halve the lemon.

While prepping, melt 8 oz unsalted butter in a small saucepan over low heat with the minced garlic and 3 sprigs fresh thyme.

Let this infuse gently for 5-7 minutes, stirring occasionally, until fragrant and the garlic becomes golden but doesn’t brown—this creates a silky, flavorful sauce that’s the heart of the dish.

Step 2: Build the Aromatic Boiling Base

• 1 large onion, whole
• 1 garlic bulb, sliced horizontally
• 1 lemon, halved
• 2 tablespoons Old Bay seasoning
• 1/4 cup Cajun seasoning
• salt to taste

Fill a large pot (at least 8-quart capacity) with water and bring to a rolling boil.

Add the whole onion, garlic bulb (sliced horizontally to expose cloves), 1 lemon cut in half, 2 tablespoons Old Bay seasoning, 1/4 cup Cajun seasoning, and a generous pinch of salt.

Let this simmer for 2-3 minutes so the aromatics and seasonings infuse into the water and create a flavorful base—this is what gives the shrimp boil its signature taste.

Step 3: Cook Potatoes First for Even Doneness

• 1.5 lbs potatoes from Step 1

Add the prepared potato chunks to the boiling seasoned water and let them cook for 5-8 minutes until they’re just starting to become tender but still hold their shape.

I like to test one with a fork to ensure they’re cooking at the right pace.

Starting potatoes first is crucial because they take longer than everything else and need a head start to finish cooking at the same time as the other ingredients.

Step 4: Add Corn and Kielbasa

• 4 ears corn from Step 1, cut into 3-inch rounds
• 1 lb kielbasa from Step 1, sliced into coins

Once the potatoes have been cooking for about 5-8 minutes, add the corn rounds and kielbasa coins to the pot.

Stir gently and let everything cook together for 2-3 minutes, allowing the kielbasa to warm through and the corn to start softening while the potatoes finish cooking.

Step 5: Finish with Shrimp and Drain

• 1.25 lbs shrimp

Add the shrimp to the pot and let everything cook together for 3-4 minutes until the shrimp turn pink and opaque—don’t overcook or they’ll become rubbery.

Once done, carefully drain all the water using a colander, reserving the cooked ingredients.

Transfer everything to a large serving platter or bowl, removing and discarding the whole onion, garlic bulb, and lemon halves from the boiling base.

Step 6: Finish and Serve with Garlic Butter and Garnish

• garlic butter sauce from Step 1
• 1/2 lemon, juice
• 1/4 cup fresh parsley from Step 1, chopped

Pour the warm garlic butter sauce from Step 1 over all the cooked ingredients, gently tossing to coat everything evenly.

Squeeze fresh lemon juice from the half lemon over the top, sprinkle with the chopped fresh parsley, and add extra salt if needed.

Serve immediately while everything is hot and the butter is flowing—this is a dish best enjoyed family-style right from the platter.
