Ingredients
- Shrimp (1 lb / 450g): The star of the show. For the best texture and flavor, opt for large or jumbo shrimp (16-20 count per pound). Wild-caught shrimp often have a more robust, “shrimpier” flavor, while farmed shrimp can be milder. You can use fresh or frozen; if using frozen, ensure they are fully thawed and patted completely dry before cooking. This is crucial for getting a good sear rather than just steaming them. The shrimp should be peeled and deveined. You can buy them this way to save time or do it yourself. Don’t discard the shells! You can freeze them to make a flavorful seafood stock later. On a keto diet, shrimp are a powerhouse of lean protein with virtually zero carbs.
- Unsalted Butter (6 tablespoons / 85g): This is the soul of the scampi sauce. Using unsalted butter gives you complete control over the saltiness of the final dish. Grass-fed butter is a fantastic choice here, as it has a higher fat content and a richer, more complex flavor that truly shines in a simple sauce like this. We use a generous amount to create a luscious, emulsified sauce that coats every piece of shrimp and zoodle.
- Extra Virgin Olive Oil (2 tablespoons / 30ml): Olive oil serves a dual purpose. First, it adds its own wonderful, slightly peppery flavor that complements the garlic and lemon beautifully. Second, it has a higher smoke point than butter, so adding it to the pan alongside the butter helps prevent the milk solids in the butter from browning too quickly and burning.
- Garlic (6-8 cloves, minced): This is not the time for pre-minced jarred garlic. Freshly minced garlic is non-negotiable for authentic scampi flavor. The pungent, sharp aroma that blooms when it hits the hot butter and oil is the heart of the dish. The amount is a suggestion; if you’re a true garlic lover, feel free to add more! Just be careful not to let it burn, as it will become bitter and ruin the sauce.
- Dry White Wine (1/4 cup / 60ml): This adds a critical layer of acidity and complexity that cuts through the richness of the butter. A dry, crisp white wine like a Pinot Grigio, Sauvignon Blanc, or an unoaked Chardonnay is perfect. The alcohol cooks off, leaving behind a sophisticated flavor. If you prefer to cook without alcohol, you can substitute it with an equal amount of chicken broth or seafood stock, with an extra squeeze of lemon juice at the end to mimic the acidity.
- Lemon (1 large): We use both the zest and the juice of the lemon. The zest, which contains the lemon’s essential oils, adds a fragrant, aromatic quality without a ton of sourness. The juice, added at the end, provides a bright, acidic kick that lifts all the flavors and keeps the dish from feeling heavy. Always use a fresh lemon for this.
- Fresh Parsley (1/4 cup, chopped): Fresh herbs are essential for finishing a dish. Flat-leaf (Italian) parsley has a more robust flavor than curly parsley. It adds a fresh, clean, and slightly peppery note that balances the rich sauce. It also adds a beautiful pop of green color.
- Red Pepper Flakes (1/4 teaspoon, or to taste): This adds a gentle, background warmth that elevates the dish from good to great. It’s not meant to make the dish spicy, but rather to provide a subtle counterpoint to the other flavors. You can easily adjust the amount based on your preference for heat.
- Salt and Black Pepper (to taste): Seasoning is crucial. We’ll season the shrimp directly and then adjust the sauce at the end. Use a good quality sea salt or kosher salt and freshly ground black pepper for the best results.
- For Serving: Zucchini Noodles (4 medium zucchini, spiralized): This is our low-carb, gluten-free answer to pasta. Spiralizing medium-sized zucchini creates the perfect “zoodles.” We’ll discuss how to prepare them to avoid a watery mess in the tips section.
Instructions
Prep Time (10 minutes):
- Prepare the Shrimp: If your shrimp are frozen, thaw them completely. The best way is to place them in a colander under cold running water for a few minutes. Once thawed, peel and devein them if they aren’t already. Most importantly, pat them thoroughly dry with paper towels. A dry surface is essential for searing.
- Season the Shrimp: Place the dried shrimp in a bowl. Season generously with salt and freshly ground black pepper. Toss to coat evenly.
- Prepare Aromatics & Herbs: Mince the garlic cloves. Zest the entire lemon into a small bowl, then cut the lemon in half and set aside for juicing later. Finely chop the fresh parsley.
- Prepare Zoodles: If you haven’t already, spiralize your zucchini. Place the zoodles in a colander over the sink. This is a good time to lightly salt them to draw out excess water while you cook the shrimp.
Cook Time (10 minutes):
- Heat the Pan: Place a large skillet or sauté pan over medium-high heat. Add the 2 tablespoons of olive oil and 2 tablespoons of the butter. Let the butter melt and foam.
- Sear the Shrimp: Carefully arrange the seasoned shrimp in a single layer in the hot pan. Do not overcrowd the pan; cook in two batches if necessary. Sear the shrimp for 60-90 seconds per side, just until they turn pink and opaque. They will have a beautiful golden-pink color. They will finish cooking in the sauce later, so be careful not to overcook them at this stage.
- Remove Shrimp: Using tongs, immediately remove the seared shrimp from the skillet and set them aside on a plate.
- Build the Sauce Base: Reduce the heat to medium-low. Add the remaining 4 tablespoons of butter to the skillet. Once it has melted, add the minced garlic and red pepper flakes. Sauté for about 30-60 seconds, stirring constantly, until the garlic is fragrant. Watch it closely—if it browns, it will become bitter.
- Deglaze the Pan: Pour in the dry white wine (or chicken broth). Use a wooden spoon or spatula to scrape up any browned bits (the “fond”) from the bottom of the pan. This is where a huge amount of flavor is. Let the wine simmer and reduce by about half, which should take about 2-3 minutes.
- Finish the Sauce: Turn off the heat. Stir in the lemon zest and the juice from half the lemon.
- Reunite and Finish: Return the cooked shrimp to the skillet. Add the chopped fresh parsley. Toss everything together to coat the shrimp in the glorious garlic butter sauce. The residual heat from the sauce will gently warm the shrimp through.
- Taste and Adjust: Taste the sauce. Add more salt, pepper, or a squeeze of juice from the remaining lemon half if you feel it needs more brightness.
