How to Make Slow Cooker Garlic Butter Shrimp Boil
Step 1: Prepare the Potatoes
Wash the baby potatoes thoroughly.
Cut larger potatoes in half so they cook evenly.
Place the potatoes in the bottom of the slow cooker.
Because potatoes take longer to cook than shrimp and corn, they should go in first.
Step 2: Add the Sausage and Corn
Add the sliced smoked sausage and corn pieces over the potatoes.
Spread everything out as evenly as possible.
The combination of sausage, corn, and potatoes creates the hearty base of this easy Crock Pot seafood boil.
Step 3: Make the Garlic Butter Sauce
In a small bowl, combine:
- Melted butter
- Minced garlic
- Seafood seasoning
- Smoked paprika
- Black pepper
- Onion powder
- Red pepper flakes
Stir until well combined.
Reserve a small amount of the garlic butter for serving if desired.
Step 4: Add the Broth
Pour the chicken or seafood broth into the slow cooker.
Drizzle about half of the garlic butter mixture over the potatoes, sausage, and corn.
Add the lemon slices.
Cover and cook on:
LOW for 4–5 hours
or
HIGH for 2–3 hours
The potatoes should be fork-tender before adding the shrimp.
Step 5: Add the Shrimp
Once the potatoes are tender, add the shrimp to the slow cooker.
Drizzle the remaining garlic butter mixture over the shrimp.
Gently stir to distribute the seasoning.
Cover and cook for approximately 15–25 minutes, or until the shrimp are opaque and cooked through.
Shrimp cook much faster than potatoes, so adding them near the end helps prevent overcooking.
Step 6: Finish with Fresh Lemon and Parsley
Remove the lemon slices if desired.
Squeeze fresh lemon juice over the shrimp boil.
Sprinkle generously with chopped fresh parsley.
Taste and add more seafood seasoning or black pepper if needed.
Step 7: Serve
Serve the shrimp boil hot, either directly from the slow cooker or spread onto a large serving platter.
