Why This Recipe Works
Scampi’s brilliance is simplicity: fat, garlic, acid, seafood. Shrimp sear quickly over high heat, then come out before overcooking. Garlic cooks in the same pan with butter and olive oil just until fragrant — never browned, since burnt garlic turns bitter and ruins the sauce.
White wine deglazes the pan, lifting caramelized bits into the sauce as the alcohol cooks off. Lemon juice and zest go in off the heat to stay bright; parsley finishes with color and freshness. Red pepper flakes are optional but recommended.
Zucchini noodles cook in the same pan in two minutes, letting the sauce dominate. It’s a keto natural: shrimp protein, butter and olive oil fats, and only modest carbs. Garlic’s allicin, olive oil’s polyphenols, and lemon’s vitamin C make it as nourishing as it is indulgent.
Ingredients
- 1 1/2 lb (680 g) large shrimp, peeled and deveined, tails on for presentation
- 4 medium zucchini (about 2 lb / 900 g), spiralized into noodles
- 4 tbsp (60 g) unsalted butter, divided
- 2 tbsp (30 ml) extra-virgin olive oil
- 6 garlic cloves, thinly sliced
- 1/2 tsp red pepper flakes, plus more to taste
- 1/2 cup (120 ml) dry white wine (such as Pinot Grigio)
- 1 lemon, zested and juiced (about 3 tbsp / 45 ml juice)
- 1 tsp (6 g) fine sea salt, divided, plus more to taste
- 1/2 tsp freshly cracked black pepper
- 1/2 cup (15 g) fresh flat-leaf parsley, chopped
- 1/4 cup (25 g) grated Parmesan cheese, for serving (optional)
- Lemon wedges, for serving
Step-by-Step Instructions
- Pat the shrimp completely dry with paper towels and season with 1/2 teaspoon of the salt and the black pepper. Dry shrimp sear properly; wet shrimp steam.
- Heat 1 tablespoon of the olive oil and 1 tablespoon of the butter in a large skillet over medium-high heat until the butter foams. Add half the shrimp in a single layer and sear for 1 to 2 minutes per side, until pink and lightly golden. Transfer to a plate. Repeat with the remaining shrimp, adding a touch more oil if needed. Do not crowd the pan.
- Reduce the heat to medium. Add the remaining tablespoon of olive oil to the same skillet, then the sliced garlic and red pepper flakes. Cook, stirring, for 45 to 60 seconds until fragrant and just turning golden at the edges — not brown.
- Pour in the white wine, scraping up all the browned bits from the bottom of the pan. Simmer for 2 to 3 minutes, until reduced by about half and the raw alcohol smell has cooked off.
- Stir in the remaining 3 tablespoons of butter, the lemon zest, and lemon juice, swirling until the butter melts into a glossy sauce. Taste and adjust salt — the sauce should be bright, garlicky, and well-seasoned.
- Add the zucchini noodles directly to the sauce and toss for 1 to 2 minutes, just until barely softened and coated. They should still have a slight bite.
- Return the shrimp (and any accumulated juices) to the pan and toss everything together for 30 seconds to warm through.
- Remove from the heat, shower with the chopped parsley, and serve immediately with Parmesan (if using) and lemon wedges.
Nutrition & Macros
Estimates per serving. The wine contributes minimal residual carbs after reduction; most of the carbs come from the zucchini and lemon.

Tips & Variations
- Slice, don’t mince, the garlic. Thin slices turn sweet and golden in the butter; minced garlic burns in seconds at this heat. This one detail separates good scampi from great.
- Don’t skip the wine. It adds irreplaceable depth — but in a pinch, substitute chicken broth with an extra squeeze of lemon.
- Add greens. A few handfuls of baby spinach or arugula wilted into the hot zoodles add color and nutrients without changing the character of the dish.
- Make it dairy-free. Use all olive oil (or ghee for a buttery flavor without milk proteins) in place of the butter.
- Try scallops. Large sea scallops, seared hard for 90 seconds per side, make a luxurious variation — pat them very dry first for a proper sear.
- Double the sauce. If you love extra sauce for spooning, increase the butter and wine by half. No one has ever complained about too much scampi sauce.
Storage & Meal Prep
Scampi is best eaten fresh — shrimp toughen with reheating and zoodles release water as they sit. That said, leftovers refrigerate well for up to 2 days in an airtight container; reheat very gently in a skillet over low heat just until warmed through. For meal prep, cook the shrimp and sauce ahead and refrigerate, then sauté fresh zoodles and combine when ready to eat — the whole assembly takes five minutes.
The sauce (without shrimp or zoodles) can be made a day ahead and refrigerated; rewarm gently before adding freshly cooked shrimp and zoodles for a nearly-instant dinner.
FAQs
Can I use frozen shrimp?
Yes. Thaw overnight in the refrigerator or under cold running water, then pat extremely dry — this matters even more with previously frozen shrimp, which hold extra moisture. Cook exactly as directed.
Is white wine keto?
Dry white wine has about 2 to 3 grams of carbs per 5-ounce glass, and this recipe uses half a cup across four servings, most of whose alcohol cooks off. The residual carbs per serving are negligible, well within keto limits.
How do I keep zucchini noodles from getting soggy?
Cook them in the sauce for only 1 to 2 minutes and serve immediately. Salting the raw zoodles for 10 minutes and patting dry beforehand also helps, as does using a hot pan so moisture evaporates rather than pools.
Can I make this without wine?
Absolutely. Replace the wine with an equal amount of chicken broth plus an extra tablespoon of lemon juice. You will lose a little complexity but keep all the garlicky, buttery character.
