Nutrition Information
- 1 pound large shrimp, peeled and deveined (tails on or off)
- 1 pound snow crab legs or clusters, thawed if frozen
- 4 small red potatoes, halved
- 2 ears corn on the cob, cut into 3 pieces each
- 1 smoked sausage (like Andouille), sliced into coins
- 1 whole lemon, cut into wedges
For the Legendary Garlic Butter Sauce:
- 1 cup (2 sticks) unsalted butter
- 8-10 garlic cloves, minced
- 3 tablespoons Cajun seasoning (use your favorite brand!)
- 1 tablespoon Old Bay seasoning
- 1 teaspoon smoked paprika
- 1/2 teaspoon crushed red pepper flakes (optional, for heat)
- 1/4 cup fresh parsley, chopped
- Juice of 1/2 a lemon
Let’s Get Cooking! (The Step-by-Step)
Ready? This moves fast. Get your biggest pot or Dutch oven. We’re doing this in stages to make sure everything cooks perfectly.
- Boil the potatoes and corn. Fill your large pot with water and add a big pinch of salt. Bring it to a boil. Add the potato halves and cook for 10 minutes.
- Add the corn. After 10 minutes, add the corn pieces to the pot with the potatoes. Let them boil together for another 5 minutes. We want them just tender.
- Drain the veggies. Use a colander to drain the potatoes and corn. Set them aside in a big bowl. No need to wash the pot yet!
- Start the magic sauce. In the same pot, melt the butter over medium heat. Add all the minced garlic. Cook for just 1 minute until it’s fragrant. Don’t let it burn!
- Mix the spices. To the garlic butter, add the Cajun seasoning, Old Bay, smoked paprika, and red pepper flakes. Stir and let it sizzle for 30 seconds. This blooms the spices and makes the flavor incredible.
- Build your boil. Turn the heat to medium-high. Add the sliced sausage and let it brown for 2-3 minutes. Then, add back the cooked potatoes and corn. Toss to coat in the sauce.
- Cook the seafood. Add the crab legs and toss. Put a lid on the pot and let everything steam and heat through for 4-5 minutes. Finally, add the raw shrimp and lemon wedges. Cover again and cook for 2-3 more minutes, just until the shrimp are pink and opaque.
- Finish and serve. Turn off the heat. Stir in the fresh lemon juice and chopped parsley. Give one final, glorious toss. That’s it!
What to Serve With This Dish
This is a full meal in a pot. But you need something to soak up that amazing sauce. Trust me on this.
Keep it simple. A baguette or crusty bread is non-negotiable. It’s your edible spoon for the garlic butter. For another fantastic skillet meal that’s perfect with bread, check out this Garlic Butter Steak and Potatoes Skillet.
For a fresh side, a bag of pre-washed coleslaw mix is perfect. Toss it with a little vinegar and oil. It cuts through the richness.
That’s all you need. No complicated sides. Just more napkins.
Make This Recipe Your Own (Quick Swaps)
Don’t have crab? No problem. This recipe is your playground. Use what you like and what’s on sale.
Here are my favorite easy swaps to keep this recipe flexible and stress-free.
- Swap the Protein: Use mussels, clams, or scallops instead of crab. Chicken thighs (cut small) work great too! For a quicker chicken option with the same garlic butter magic, my Garlic Butter Chicken Bites are a huge hit. Just cook them a bit longer before adding the shrimp.
- Swap the Veggies: Try baby carrots or chunks of onion with the potatoes. Green beans or asparagus added with the shrimp cook fast and add color.
- Control the Heat: Use a mild Cajun seasoning if you’re sensitive to spice. Leave out the red pepper flakes. On the flip side, add a dash of hot sauce to the butter for more kick.
How to Store Leftovers (If You Have Any!)
It’s rare, but it happens. Store everything in a sealed container in the fridge for up to 2 days.
Reheat gently in a covered skillet with a splash of water or broth. The microwave can make the seafood rubbery.
The sauce might solidify when cold. That’s just the butter. It will melt back into perfection when warmed.

FREQUENTLY ASKED QUESTIONS
Can I use frozen seafood?
Absolutely! Just thaw it in the fridge overnight first. This helps it cook evenly and prevents a watery sauce.
My family doesn’t like spicy food. What do I do?
Easy. Use a mild Cajun seasoning and skip the red pepper flakes. The dish will still have tons of herb and garlic flavor without the heat.
Do I need a special pot?
Nope! Any large soup pot or Dutch oven works. If you’re doubling the recipe, use your biggest stockpot.
See? I told you it was simple. From stressed to impressed in half an hour. That’s a win in my book.
