Season the pot hard
Fill a large stockpot with enough water to cover the ingredients. Add onion, garlic, lemon, seafood seasoning and salt. Bring to a boil and simmer 5 minutes.

Potatoes, corn and smoky sausage in a boldly seasoned pot — with the shrimp added only at the very end so they stay plump instead of paying for everyone else’s cook time.

Fill a large stockpot with enough water to cover the ingredients. Add onion, garlic, lemon, seafood seasoning and salt. Bring to a boil and simmer 5 minutes.
Add potatoes and boil until almost tender, 12 to 15 minutes depending on size.
Add sausage and corn and cook 5 minutes more. Check a potato; it should be tender now.
Reduce the heat so the water is no longer rolling aggressively.
Add the shrimp and cook 2 to 4 minutes, stirring once, just until opaque. Do not wait for a dramatic curl.
Drain the pot immediately. Discard the aromatics or pile everything onto a paper-lined table or large platter.
Toss with melted butter, lemon juice, parsley and a light final dusting of seafood seasoning. Serve hot.
OPTIONAL UPGRADE
Keep the core recipe clean, or flip this on for one or two high-impact upgrades.
Use these recipe-specific texture cues. Color and curl alone cannot establish safety; use a thermometer to check 145°F / 63°C at the thickest part for cooked shrimp.
The little details that make a big difference.
Potatoes get fifteen minutes. Shrimp gets a few. One pot does not mean one timer.
The shell protects the shrimp and lets the seasoned water flavor the exterior without washing out the meat.
16/20 to 21/25 gives you a wider window while you drain a heavy pot.
A little seasoning in the butter tastes brighter than dumping everything into the water.
