Prep the Vegetables: Halve the potatoes, cut the corn into thirds, and quarter the onion.
Seasoning Mix: In a small bowl, combine Old Bay, paprika, garlic powder, and salt. This blend will add a delicious, bold flavor to the boil.
Add Water and Seasonings: In your large stockpot, fill with water to about two-thirds full, enough to submerge all ingredients. Squeeze the lemon halves into the pot, then toss them in along with the smashed garlic and onion.
Add Seasonings: Stir in the seasoning blend and bring the pot to a rolling boil.
Cook in StagesAdd Potatoes: Once the water is boiling, add the potatoes. Let them cook for about 10-12 minutes until they’re starting to soften. Add Sausage and Corn: Add the smoked sausage and corn to the pot. Cook for an additional 8-10 minutes until both are nearly tender.
Add Crab and Shrimp: Carefully add the crab to the pot and cook for 5-10 minutes, depending on whether the crab is fresh or pre-cooked (if it’s pre-cooked, just heat until warmed through). If using shrimp, add them in the last 5 minutes, as they cook quickly.
Taste and Adjust: Taste the broth and adjust seasoning if needed.
Drain and Serve: Once everything is perfectly cooked, use tongs to carefully transfer the ingredients to a large strainer to drain. Lay out newspaper on your serving table or use a large serving platter.
Garnish: Sprinkle fresh parsley over the top and serve with melted butter on the side for dipping.
