🛒 The Simple Ingredients
This recipe proves you don’t need a complicated grocery list to create a restaurant-quality meal. Here is what you will need (plus a pinch of salt!):
- Frozen Shrimp: 2 pounds of raw, frozen shrimp (peeled and deveined, tail-on or tail-off). Do not thaw them first!
- Butter: 1 cup (2 sticks) of salted butter, melted. This forms the rich, luxurious base of the sauce.
- Garlic: 4 large cloves, finely minced (or 1 ½ tablespoons of jarred minced garlic) for that classic scampi flavor.
- Italian Seasoning: 1 teaspoon of dried Italian seasoning (or a blend of dried parsley, basil, and oregano).
- Kosher Salt: 1 teaspoon, to perfectly balance and elevate the flavors.
📖 Step-by-Step Instructions
Follow these easy steps for an effortless seafood dinner:
Step 1: Prep the Slow Cooker
Place the raw, frozen shrimp in an even layer in the bottom of a 4- to 6-quart slow cooker. Remember, they should go in straight from the freezer!
Step 2: Mix the Garlic Butter
In a small bowl or measuring cup, whisk together the melted butter, minced garlic, kosher salt, and dried Italian seasoning. Stir well so the garlic and herbs are evenly dispersed.
Step 3: Pour and Coat
Pour the melted butter mixture evenly over the frozen shrimp in the slow cooker, making sure to cover as much of the surface as you can. Use a spatula to gently nudge the shrimp so some of the seasoned butter slips underneath.
Step 4: Slow Cook
Cover the slow cooker with the lid and cook on LOW for 1 to 1 ½ hours. Cooking times can vary depending on the size of the shrimp, so keep an eye on them.
Step 5: Stir Halfway
About halfway through the cooking time, gently stir the shrimp once to redistribute the garlic butter and ensure even cooking. Replace the lid promptly so you don’t lose too much heat.
Step 6: Serve Immediately
As soon as the shrimp are fully opaque and pink throughout, turn off the slow cooker to prevent overcooking. Serve immediately with plenty of the garlic butter spooned over the top!
💡 Expert Tips for Success
- Watch the Clock: Overcooked shrimp become rubbery very quickly. Start checking them right at the 1-hour mark to ensure they stay perfectly tender. Do not use the “Warm” setting for extended periods.
- Safe Thawing: Always start with shrimp that are individually quick frozen (IQF) and safe for cooking from frozen. Keep them in the freezer until the exact moment you are ready to put them in the slow cooker.
- Taste and Adjust: Right before serving, taste the garlic butter sauce. If your butter was unsalted, add a pinch more salt, or squeeze in a splash of fresh lemon juice if you prefer a brighter flavor.
- The Perfect Pairing: Sparkling water with a fresh wedge of lemon is incredibly refreshing alongside this rich, buttery dish!
✨ Creative Variations
Want to make this recipe your own? Try these fun twists:
- Turn Up the Heat: For a spicy kick, stir ¼ to ½ teaspoon of crushed red pepper flakes into the melted butter before pouring it over the shrimp.
- Mediterranean Brightness: Add the finely grated zest of 1 lemon to the butter mixture, and finish the cooked shrimp with a squeeze of fresh lemon juice and a handful of chopped fresh parsley.
- Cajun Style: Swap the Italian seasoning and salt for 2 teaspoons of your favorite Cajun or Creole seasoning blend (just be mindful of the salt levels in the blend!).
- Lighter Swap: For a slightly lighter dish, use ¾ cup of melted butter and ¼ cup of high-quality olive oil. This still provides incredible richness but with a bit more balance.
❓ Frequently Asked Questions
Can I use pre-cooked frozen shrimp?
No, it is highly recommended to use raw frozen shrimp. Pre-cooked shrimp will quickly become overcooked, rubbery, and tough when heated in the slow cooker.
What size shrimp is best?
Any size will work, but cooking times will vary! If your shrimp are jumbo or extra-large (like U-15 or U-10), expect the cook time to be closer to 1 ½ hours. Smaller shrimp will cook faster.
How do I store and reheat leftovers?
Refrigerate any leftovers in an airtight container within 2 hours of cooking. To reheat, warm them very gently on the stovetop over low heat just until warmed through to avoid overcooking.
