1-First step: Build the seasoned broth Fill a large pot with 4 quarts of hot water. Using hot water helps the pot come to a boil faster, which saves time and gets dinner moving. Add the onion wedges, halved garlic bulb, seafood boil seasoning, and thyme. Stir everything together, then bring the pot to a boil over medium-high heat.

2-Second step: Cook the potatoes first Add the quartered red potatoes once the broth is boiling. Season with salt and pepper, using about 1 tablespoon of salt if you want the flavor to be well balanced. Let the potatoes cook for 10 to 15 minutes, or until they are nearly tender. They should still hold their shape because they will keep cooking with the corn, sausage, and shrimp.

3-Third step: Add the corn and sausage Once the potatoes are almost done, add the corn. Cook it for 3 minutes. Then add the sliced andouille sausage and cook for 4 minutes longer. This short simmer gives the corn time to soak up flavor and allows the sausage to warm through without getting tough.

4-Fourth step: Add the shrimp at the end Stir in the shrimp and cook only until they turn opaque and pink, about 1 to 2 minutes. Shrimp cooks very fast, so watch closely. If you leave it in too long, it can turn rubbery and lose that tender bite that makes a one pot shrimp boil so good.

5-Fifth step: Drain and plate Drain the mixture, but save up to 1/4 cup of the broth if you want a little extra flavor later. Spread the potatoes, corn, sausage, and shrimp on a large serving platter or baking sheet. This makes the meal feel festive and gives everyone room to pick their favorites. A newspaper-lined table is a fun old-school option for a Southern-style gathering.

6-Final step: Finish with butter, lemon, and parsley Drizzle the melted unsalted butter and lemon juice over the top. Sprinkle with parsley, a little more seafood boil seasoning if you want extra punch, and black pepper to taste. Serve warm right away. The butter gives the shrimp boil a glossy finish, while the lemon juice cuts through the richness and keeps each bite bright.
