Step-by-Step Instructions for One Pot Snow Crab and Shrimp
Step 1: Prepare Your Ingredients
Begin by washing potatoes thoroughly and cutting them into halves (or quarters for larger ones). Slice corn into thirds, quarter the onion, and slice the top off the garlic head. This preparation ensures even cooking and maximum flavor absorption.
Step 2: Start with the Potatoes
Fill a large stockpot with 4 quarts of water. Add 3 tablespoons of Old Bay seasoning, 2 tablespoons of cajun seasoning, bay leaves, and apple cider vinegar. Bring to a rolling boil, then add potatoes. Cook for about 10 minutes until the potatoes are just beginning to soften when pierced with a fork.
Step 3: Add Corn and Aromatics
Add corn, onion quarters, garlic head, and lemon slices to the pot. Continue to boil for 5 minutes. The starchiness from the potatoes creates a flavor base that the corn will absorb beautifully.
Step 4: Introduce the Seafood
Gently add the snow crab legs and shrimp to the pot. Cook for about 5 minutes until the shrimp turn pink and opaque and the crab is heated through. Pro tip: Arrange the seafood on top rather than stirring it in—this prevents overcooking and keeps the crab legs intact.
Step 5: Season and Serve
Drain the boil in a large colander, then transfer to a serving platter or parchment paper-covered table. Drizzle with melted butter and olive oil, then sprinkle with the remaining Old Bay seasoning. Garnish with fresh parsley and serve with lemon wedges for squeezing.
