Why Cooking Shrimp in a Slow Cooker Works
Shrimp are notoriously easy to overcook on a blazing stovetop, often turning rubbery in seconds. Using a slow cooker offers a gentle, controlled heat environment that allows the butter, garlic, and fresh citrus to meld together into a rich sauce while keeping the shrimp delicate, plump, and perfectly tender.
Because shrimp cook quickly even at low temperatures, this is one of the fastest slow cooker recipes you’ll ever make—taking less than an hour from start to finish!
Complete Ingredient List
To prepare this effortless seafood dish, gather the following ingredients:
- Shrimp: 1 ½ lbs (680 g) large shrimp, peeled and deveined (fresh or thawed)
- Butter: 4 tbsp (56 g) unsalted butter, cut into small cubes
- Garlic: 5 cloves (15 g) fresh garlic, finely minced
- Lemon Juice: 2 tbsp (30 ml) freshly squeezed lemon juice
- Lemon Slices: 1 fresh lemon (120 g), thinly sliced into wheels
- Seasonings:
- ½ tsp (1 g) paprika
- ½ tsp (3 g) sea salt
- ¼ tsp (0.5 g) freshly cracked black pepper
- Garnish: ¼ cup (15 g) fresh parsley, chopped
- For Serving: Fresh lemon wedges
Optional Serving Suggestions:

Expanded Step-by-Step Cooking Instructions
Step 1: Create the Flavor Base
In the bottom of your slow cooker basin, scatter the cubed unsalted butter evenly. Add the finely minced garlic, freshly squeezed lemon juice, paprika, sea salt, and black pepper. Stir gently to distribute the seasonings into the butter cubes.
Step 2: Layer the Lemon Slices
Arrange the thin lemon slices in a single layer over the seasoned butter mixture. This forms a citrus-infused aromatic bed that prevents the shrimp from coming into direct contact with the bottom heating element.
Step 3: Add and Season the Shrimp
Pat the peeled and deveined shrimp dry with paper towels. Lay the shrimp in an even layer directly over the lemon slices, ensuring they are spread out for uniform cooking.
Step 4: Slow Cook to Perfection
Cover the slow cooker securely with the lid and set your temperature:
- LOW Setting (Recommended): Cook for 30 to 45 minutes.
- HIGH Setting: Cook for 20 to 30 minutes.
- (Note: Keep a close eye on the shrimp toward the end. They are fully cooked as soon as they turn opaque and pink in color).
Step 5: Toss with Parsley and Rest
Once cooked, turn off the slow cooker. Sprinkle the fresh chopped parsley over the warm shrimp and gently toss everything together using a spoon, coating every piece of shrimp in the warm, glossy garlic-lemon butter sauce.
Step 6: Plate and Serve
Transfer the lemon garlic shrimp immediately onto a platter or serve over warm white rice, pasta, or alongside crusty bread to catch every drop of the buttery garlic sauce. Serve with fresh lemon wedges on the side for an extra burst of acidity.
Serving Suggestions & Storage Tips
- Pairings: Serve with a crisp green side salad or roasted asparagus to balance the rich butter sauce.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 2 days.
- Reheating: Reheat gently on the stovetop over low heat with a splash of water or extra butter just until warmed through to prevent overcooking the shrimp.
