Ingredients for Garlic Butter Shrimp
2 pounds raw frozen shrimp (peeled and deveined)
Shrimp are the star of this recipe. Using frozen shrimp makes this incredibly convenient because they can go directly into the slow cooker. Choose large or jumbo shrimp for the best texture and juiciness.
1 cup salted butter, melted
Butter creates the rich, velvety base of the sauce. It helps carry the garlic and seasoning into every bite while keeping the shrimp moist and flavorful.
4 large garlic cloves, minced
Fresh garlic delivers bold aromatic flavor that makes this dish stand out. Garlic and butter together create the classic combination that makes shrimp dishes so irresistible.
1 teaspoon kosher salt
Salt enhances the natural sweetness of the shrimp and balances the richness of the butter.
1 teaspoon dried Italian seasoning
This adds layers of herbaceous flavor, including notes of basil, oregano, and parsley, making the dish more complex without extra work.
How to Make Slow Cooker Garlic Butter Shrimp
Step 1: Add the Frozen Shrimp
Place the frozen shrimp in a single even layer at the bottom of your slow cooker. Make sure the shrimp remain frozen—this helps them cook evenly and prevents them from entering unsafe temperature zones too soon.
Step 2: Prepare the Garlic Butter Sauce
In a medium bowl, combine the melted butter, minced garlic, kosher salt, and Italian seasoning. Stir thoroughly until the garlic and herbs are evenly distributed.
Step 3: Pour Over the Shrimp
Slowly pour the garlic butter mixture over the frozen shrimp. Use a spoon or spatula to gently move the shrimp around so the buttery sauce coats every piece.
Step 4: Cook Low and Slow
Cover the slow cooker with the lid and cook on LOW for 1 to 1½ hours. Shrimp cook quickly, so avoid overcooking.
Step 5: Stir Halfway Through
At the halfway point, stir the shrimp gently to ensure even cooking and redistribute the garlic butter sauce.
Step 6: Check for Doneness
The shrimp are ready when they turn pink, opaque, and slightly firm. Start checking at the 1-hour mark.
Step 7: Serve Immediately
Spoon the shrimp and all that delicious garlic butter sauce over your chosen side dish and enjoy immediately.
