This Louisiana-style dish combines succulent shrimp, sweet corn, spicy Andouille sausage, and tender baby potatoes simmered with rich Cajun seasoning. Bright lemon slices and garlic infuse the broth, while a splash of beer adds depth. The boil finishes coated in melted butter and fresh parsley, creating a perfect balance of bold, comforting flavors. Ideal for gatherings, it offers a quick 50-minute preparation with a satisfying blend of textures and spice.

Last Mardi Gras, my kitchen turned into the best kind of chaos. Friends kept dropping by, and somehow I ended up feeding twelve people with nothing but a giant pot and whatever I could grab from the store. The shrimp boil saved me, and honestly, seeing everyone gathered around that steaming platter, hands messy, laughter bouncing off the walls, that is what I think about whenever I smell Cajun spices now.

I learned this the hard way: do not skip the newspaper. My friend Sarah spread it across her table like we were at a real Louisiana crawfish boil, and something about that casual, no-plates-necessary setup made everyone relax. We spent three hours eating, talking, and picking through the pile for the best pieces of sausage.

Ingredients

  • Large raw shrimp: Keep the shells on because they protect the meat and add incredible flavor to the broth
  • Baby red potatoes: These hold their shape better than larger potatoes and look beautiful on the platter
  • Corn: Fresh corn cut into thirds is traditional, but frozen works in a pinch
  • Andouille sausage: The smoky heat is essential, but smoked sausage makes a decent substitute
  • Cajun seasoning: This is the backbone, so taste your broth and adjust before adding the shrimp
  • Garlic: Smashed cloves release more flavor into the cooking liquid than minced ones
  • Beer: A light lager adds depth, but extra water keeps it completely non-negotiable for anyone avoiding alcohol
  • Butter: Melted and drizzled at the end ties everything together with a rich finish

Instructions

Build your flavor foundation:
Combine the water, beer, Cajun seasoning, smashed garlic, bay leaves, salt, peppercorns, onion quarters, and lemon slices in your largest pot. Turn the heat to high and let it come to a rolling boil, which usually takes about 8 minutes.
Start with the potatoes:
Add the halved baby potatoes to the boiling broth and reduce heat to medium. Let them simmer for 10 minutes, checking with a fork until they are just starting to yield but still holding their shape.
Add the heavy hitters:
Toss in the sliced Andouille and corn pieces, keeping the simmer going for another 8 to 10 minutes. You will know the corn is ready when it turns bright yellow and feels tender when pierced with a knife.
The grand finale with shrimp:
Drop in the shell-on shrimp and watch closely, because they cook fast. Within 2 or 3 minutes, they will turn pink and opaque, which is your signal to immediately remove the pot from heat.
The dramatic pour:
Grab a large colander and drain everything thoroughly, discarding the bay leaves and lemon slices unless you like the rustic presentation. Dump the shrimp, vegetables, and sausage onto a huge platter or onto that newspaper-covered table I mentioned.
The finishing touches:
Drizzle everything with melted butter, scatter fresh parsley across the top, and set out lemon wedges and hot sauce so everyone can customize their own pile.

My brother-in-law, who is from Louisiana, told me that the real magic happens when you squeeze those lemon wedges over everything right before eating. It sounds small, but that hit of acid against the spicy broth and rich butter is absolutely transformative.

Getting the Timing Right

Potatoes always take the longest, so they go in first. I once made the mistake of adding everything at once, and I ended up with perfect shrimp but raw potatoes. Now I treat it like a relay race, adding each ingredient at the right moment so everything finishes cooking together.

Making It Your Own

Sometimes I throw in crab legs or clams if I am feeling fancy, and honestly, the broth handles them beautifully. Just remember that shellfish like clams need to steam until they open, while crab needs a few extra minutes. The boil is forgiving that way.

Serving Like a Local

In Louisiana, this is often dumped directly onto a newspaper-lined table, and there is something freeing about eating this way. No plates, no pretense, just good food and good company.

  • Crusty bread is non-negotiable for sopping up that spicy broth
  • Cold beer or sweet tea helps balance the heat
  • Paper towels should be within arms reach for everyone
