Ingredients for Slow Cooker Lemon Garlic Shrimp Scampi
This recipe serves about 4 people.
1.5 pounds raw shrimp, peeled and deveined
4 cloves garlic, minced
¼ cup low-sodium chicken broth
Zest of 1 lemon
¼ cup freshly squeezed lemon juice
½ teaspoon red pepper flakes (optional)
½ teaspoon freshly ground black pepper
Salt, to taste
2 tablespoons unsalted butter, sliced
2 tablespoons fresh parsley, chopped
Extra lemon wedges, for serving
Step-by-Step Instructions
Step 1: Add Shrimp to the Slow Cooker
Place the raw, peeled, and deveined shrimp in an even layer at the bottom of your slow cooker.
Step 2: Make the Lemon Garlic Sauce
In a small bowl, whisk together the minced garlic, chicken broth, lemon zest, lemon juice, red pepper flakes (if using), black pepper, and a small pinch of salt.
Step 3: Pour Sauce Over Shrimp
Pour the lemon garlic mixture evenly over the shrimp, making sure they are well coated.
Step 4: Add Butter
Slice the butter into small pieces and scatter them evenly over the shrimp. The butter will melt into the sauce, adding richness and classic scampi flavor.
Step 5: Slow Cook Gently
Cover and cook on LOW for about 2 hours, or until the shrimp turn pink and opaque.
Step 6: Garnish and Serve
Once cooked, gently stir the shrimp to coat them in the sauce. Sprinkle with freshly chopped parsley and serve immediately with extra lemon wedges for a bright finish.
