Ingredients List
For the Cajun Seafood Boil
Water
The foundation of your Cajun Seafood Boil, water helps all flavors blend beautifully. Using enough water ensures that ingredients cook evenly. Substitute half the water with beer or seafood stock for richer flavor.
Cajun & Old Bay Seasoning
Cajun seasoning adds that signature heat and depth, while Old Bay imparts a distinct, savory seafood flavor. Combine both for a perfectly balanced boil. If you can’t find these, use a mix of paprika, cayenne pepper, garlic powder, onion powder, and thyme.
Hot Sauce
Essential for that spicy Cajun kick! Louisiana or Tabasco hot sauce works best. Adjust to your preferred heat level. For milder flavor, substitute with a pinch of red pepper flakes or omit altogether.
Onion
Whole onions add sweetness and depth. Use yellow or white onions, quartered. Red onions can also work but impart a slightly stronger taste.
Lemon
Fresh lemon brightens up the seafood and balances the spice. Add lemon wedges directly to the boil and extra slices for garnish. Lime can be a refreshing substitute.
Andouille Sausage
Smoky, spicy Andouille is traditional in Cajun boils. If unavailable, kielbasa, smoked sausage, or even spicy Italian sausage are excellent substitutes.
Baby Potatoes
Small, waxy potatoes hold their shape during cooking. Red or yellow baby potatoes work well. Regular potatoes can be quartered if small potatoes aren’t available.
Snow Crab Leg Clusters
Snow crab legs add sweetness and impressive presentation. Substitute with king crab legs for meatier texture or blue crabs for an authentic touch. Frozen crab legs are fine, just thaw them first.
Large Shrimp
Use shell-on, deveined shrimp for the best flavor and juiciness. Jumbo or extra-large shrimp are preferable. Frozen shrimp is a convenient alternative—just thaw in cold water before use.
Corn on the Cob
Fresh corn cut into smaller pieces absorbs spices wonderfully. If fresh corn isn’t in season, frozen corn on the cob is an excellent substitute—no need to thaw before boiling.
Hard-Boiled Eggs (optional)
A unique addition that absorbs spices, adding richness. Boil and peel before adding to the boil at the end. Omit if desired or substitute with extra potatoes.
For the Garlic Butter Sauce
Butter
Use unsalted butter for complete flavor control. If salted butter is your only option, reduce other added salt. For a healthier option, substitute half the butter with olive oil.
Garlic
Fresh minced garlic is key for bold flavor. Roasted garlic can add a sweeter, mellow flavor if preferred.
Lemon Juice
Fresh lemon juice cuts through the richness of butter. Substitute with lime juice if lemons aren’t available.
Cajun & Old Bay Seasoning
Echoes flavors from the boil. Adjust amounts to your spice preference. If unavailable, mix paprika, cayenne pepper, garlic powder, and a pinch of celery salt.
Chopped Parsley
Adds freshness, color, and mild herbaceous notes. Cilantro or green onions are good alternatives.
Smoked Paprika
Brings smoky depth, enhancing sauce complexity. Regular paprika works too, with a milder flavor.
Hot Sauce
Adds another layer of heat. Louisiana-style or Tabasco works best. For a milder sauce, reduce the amount or omit.
Step-by-Step Instructions
Step 1: Prepare Your Ingredients
Before diving into the cooking, gather and prep all your ingredients. If you’re using frozen shrimp or crab legs, make sure they’re fully thawed. Cut your baby potatoes in half if they’re larger, slice your corn on the cob into smaller pieces, and quarter your onions. Having everything prepped ensures smooth cooking and timing!
Step 2: Prepare the Boiling Liquid
Fill a large pot (at least 10-12 quarts) halfway with water. Add in your Cajun and Old Bay seasonings, hot sauce, and lemon wedges. Give it a good stir. Bring the seasoned water to a rolling boil over high heat. This flavorful liquid is what infuses your ingredients with those iconic Cajun flavors, so don’t be shy with your seasonings!
Step 3: Cook Potatoes and Sausage
Once your seasoned water is boiling, add in the baby potatoes and let them boil for about 10 minutes. Next, toss in the sliced andouille sausage and the quartered onions. Continue boiling for another 5 minutes. Potatoes need more time, so they go in first to ensure they’re perfectly tender. The sausage adds smoky flavor, and onions provide a hint of sweetness.

Step 4: Add Corn and Crab Legs
Now it’s time for your corn on the cob and snow crab legs. Carefully place them into the pot, ensuring they’re fully submerged. Let them boil for about 5 minutes. Corn absorbs all the delicious spices, while the crab legs add sweetness and oceanic richness to your boil.
Step 5: Cook the Shrimp
Add your large, shell-on shrimp into the pot last—they cook incredibly fast. Let them boil for just 2-3 minutes until they turn pink and slightly curl. Be careful not to overcook them, as they’ll turn tough. Perfectly cooked shrimp should be juicy and tender.
Step 6: (Optional) Add Hard-Boiled Eggs
If you’re using hard-boiled eggs, add them to the pot now, just long enough to warm through, about 1 minute. Eggs absorb spices beautifully, offering a creamy texture and flavor contrast.
Step 7: Drain and Serve
Carefully drain the seafood boil using a large colander, discarding the boiling liquid. Transfer everything onto a large serving platter or line your dining table with newspaper or parchment paper and spread everything out for an authentic Louisiana-style feast.
Step 8: Prepare the Garlic Butter Sauce
While the boil cools slightly, melt unsalted butter in a saucepan over medium heat. Add freshly minced garlic and sauté for about 2 minutes until fragrant. Stir in fresh lemon juice, additional Cajun and Old Bay seasonings, smoked paprika, and a splash of hot sauce. Cook for another minute until flavors meld. Finish with chopped parsley for freshness. This sauce will elevate your seafood boil from delicious to absolutely irresistible!
Step 9: Serve with Sauce and Enjoy!
Generously drizzle the garlic butter sauce over the entire seafood boil, reserving some sauce for dipping. Add extra lemon wedges and fresh parsley for garnish. Now, gather everyone around, roll up your sleeves, and dig in! It’s messy, fun, and so incredibly delicious.
Expert Tips
1. Perfect Timing Is Key
Seafood cooks quickly and can turn tough or rubbery if overcooked. Always add ingredients in stages, starting with those requiring more time (like potatoes) and ending with the quickest-cooking ones (shrimp). Use a timer and keep an eye on your pot!
2. Customize Your Spice Level
One of the joys of a Cajun Seafood Boil is that it can be easily tailored to your spice preference. If you prefer mild heat, reduce the hot sauce and Cajun seasoning. If you love spice, add more or even throw in a few sliced jalapeños or cayenne pepper to amp things up!
3. Consider Cooking Outdoors
A seafood boil can be messy but fun! Cooking outdoors using a large propane burner or turkey fryer can make cleanup a breeze and adds a fun, authentic atmosphere to your gathering. If cooking indoors, make sure your pot is large enough and have plenty of newspaper or parchment paper to line your table for easy cleanup.
4. Enhance Flavor with Broth
For an even richer, more flavorful boil, substitute half of the water with seafood stock, chicken broth, or even beer. This adds depth and complexity to the dish, making each bite unforgettable.
5. Freshness Matters
For best results, especially with seafood, use the freshest ingredients possible. Fresh shrimp and crab legs always taste best, but if using frozen, thaw them properly. Immerse frozen seafood in cold water for 20-30 minutes before cooking. Avoid thawing seafood at room temperature, which can negatively affect texture.
