• 2 tablespoons fresh lemon juice
• 1 teaspoon lemon zest
• 1 teaspoon Italian seasoning

How to Make Slow Cooker Garlic Butter Shrimp

Step 1: Thaw the Shrimp

If using frozen shrimp, thaw them overnight in the refrigerator. For faster thawing, place the shrimp in a leakproof bag and submerge in cold water, changing the water every 30 minutes until thawed.

Do not put frozen shrimp directly into the slow cooker because they may heat too slowly.

Step 2: Prepare the Shrimp

Pat the thawed shrimp dry with paper towels. Check that the shells and digestive veins have been removed. Leave the tails attached if desired for presentation.

Step 3: Make the Garlic Butter Sauce

In a small bowl, combine melted butter, minced garlic, lemon juice, lemon zest, Italian seasoning, smoked paprika, salt, black pepper, and optional red pepper flakes.

Stir until the ingredients are evenly distributed.

Step 4: Add the Shrimp to the Slow Cooker

Lightly grease the inside of a small slow cooker. Arrange the thawed shrimp in an even layer, using a cooker large enough to avoid tightly packing them.

Step 5: Pour the Butter Sauce

Pour the prepared garlic butter mixture evenly over the shrimp. Gently toss to coat every piece.

Step 6: Cook on High

Cover and cook on HIGH, checking after approximately 20 minutes. Depending on the appliance and shrimp size, cooking may take 20–40 minutes or longer.

Stir once if necessary. Shrimp are ready when opaque, firm, and cooked to an internal temperature of 145°F (63°C). Do not rely on cooking time alone.

Step 7: Finish with Parsley

Turn off the slow cooker as soon as the shrimp are cooked. Sprinkle with freshly chopped parsley and gently stir.

Avoid leaving the shrimp on the warm setting for an extended period because they can become tough.

Step 8: Serve Immediately

Spoon the shrimp and garlic butter sauce over freshly cooked rice, linguine, or mashed potatoes. Garnish with lemon wedges and additional parsley if desired.

Helpful Tips for Perfect Garlic Butter Shrimp

• Thaw shrimp completely: This promotes more even cooking.
• Choose large shrimp: They are easier to monitor and less likely to overcook than very small shrimp.
• Use fresh garlic: It provides a more pronounced flavor.
• Watch cooking time closely: Slow cookers vary significantly in how quickly they heat.
• Use a thermometer: Shrimp should reach 145°F (63°C).
• Serve promptly: Shrimp can become rubbery if kept hot too long.
