Slow Cooker Seafood Boil (Crockpot Style) 🐢🦐 Low and Slow, Buttery and Bold — Boil Flavor Without the Rush
Slow Cooker Seafood Boil is the easiest way to get all the spicy, steamy, buttery goodness of a classic boil — no stove, no watchful boiling, just layers of seafood, sausage, corn, and potatoes infused with Cajun flavor over a few hands-off hours.
Ingredients (Serves 4–6)
- 1 lb large shrimp, shell-on
- 1 lb snow crab legs or lobster tails (optional)
- 12 oz smoked sausage, sliced
- 1 lb baby potatoes
- 2–3 ears corn, halved
- 1 lemon, halved
- 4 cups water or low-sodium seafood broth
- 2 tbsp Old Bay seasoning
- 1 tbsp Cajun seasoning
- 1 tsp garlic powder
- Salt and pepper to taste
- Optional: ½ cup beer or white wine for depth
Garlic Cajun Butter (for finishing)
- ½ cup (1 stick) unsalted butter
- 4–5 garlic cloves, minced
- 1 tbsp Cajun seasoning
- Juice of ½ lemon
- Optional: hot sauce or red pepper flakes for extra heat
Instructions
Step 1: Build the Base
Place potatoes, corn, sausage, lemon halves, water (or broth), Old Bay, Cajun seasoning, garlic powder, and optional beer into the slow cooker. Stir gently to combine.
Step 2: Slow Cook
Cover and cook on high for 3–4 hours or low for 6–7 hours — until potatoes are fork-tender. Add shrimp (and crab if using) during the last 20–30 minutes of cooking. Shrimp should be pink and just cooked through.
Step 3: Make the Garlic Butter
While the seafood finishes, melt butter in a saucepan. Add garlic and cook 1–2 minutes. Stir in Cajun seasoning, lemon juice, and optional hot sauce. Keep warm.
Step 4: Serve
Drain the contents or use a slotted spoon to transfer everything to a tray or platter. Drizzle with garlic Cajun butter or serve it on the side for dipping. Garnish with lemon wedges and fresh herbs if desired.
Flavor Variations
- Add mussels or clams with the shrimp
- Stir in cooked ramen or rice noodles at the end
- Swap Cajun seasoning for lemon-pepper or garlic-herb blends
- Add a dash of smoked paprika or Worcestershire to the broth
Serving Ideas
- Serve with crusty bread, cornbread, or steamed rice
- Cold beer, sweet iced tea, or lemonade balance the heat
- Add ramekins of garlic butter or remoulade on the side
- Perfect for meal prep — leftovers reheat beautifully
Pro Tips
- Shrimp and crab go in at the end to avoid overcooking
- Use shell-on shrimp for flavor and texture
- For richer flavor, replace half the water with seafood stock
- Want more sauce? Double the butter blend and pour it all over
