Keto Zucchini Shrimp Scampi – A Bright, Garlicky Weeknight Dinner
This Keto Zucchini Shrimp Scampi brings bold garlic, lemon, and butter together in one quick skillet dish. It’s light, fresh, and satisfying without the heaviness of pasta. You’ll get all the classic scampi flavors with a fast prep and an easy cleanup.
Zucchini “noodles” keep things low-carb, while juicy shrimp cook in minutes. If you’re craving something restaurant-worthy that fits a keto lifestyle, this is it.
Ingredients
Method
- Prep the zucchini: Spiralize zucchini into noodles. Lay them on a clean kitchen towel, sprinkle lightly with salt, and let sit 10 minutes to draw out excess water. Gently squeeze or pat dry. This keeps your scampi from getting watery.
- Season the shrimp: Pat shrimp dry with paper towels. Season both sides with salt and pepper. Dry shrimp sear better and stay juicy.
- Start the aromatics: Heat a large skillet over medium heat. Add 1 tablespoon olive oil and 1 tablespoon butter. When the butter melts, add garlic and red pepper flakes. Stir for 30–45 seconds until fragrant, not browned.
- Cook the shrimp: Add shrimp in a single layer. Cook 1–2 minutes per side until just pink and opaque. Transfer to a plate. Don’t overcook, or they’ll turn rubbery.
- Deglaze and build the sauce: Add wine or broth to the skillet, scraping up any browned bits. Simmer 1–2 minutes to reduce slightly. Stir in lemon zest and juice, plus remaining 1 tablespoon butter and 1 tablespoon olive oil. If using capers, add them now.
- Cook the zoodles: Add zucchini noodles to the pan. Toss with tongs for 2–3 minutes until warmed through and crisp-tender. Avoid overcooking to prevent sogginess.
- Finish and season: Return shrimp to the skillet. Toss to coat in sauce for 30–60 seconds. Taste and adjust salt, pepper, and lemon. For a richer finish, swirl in the optional extra tablespoon of butter.
- Serve: Remove from heat. Sprinkle with parsley and Parmesan. Serve immediately with lemon wedges on the side.
Why This Recipe Works
This dish builds flavor fast by layering garlic, butter, and olive oil with a splash of lemon juice and dry white wine or broth. Shrimp cook in just a few minutes, which keeps dinner on schedule.
Zucchini noodles step in for pasta, soaking up the sauce without extra carbs. A pinch of red pepper flakes adds gentle heat, and fresh parsley keeps everything bright. The result is a balanced, buttery sauce that clings to tender shrimp and crisp-tender zoodles.

- 1/3 cup dry white wine or low-sodium chicken broth
- 1 large lemon (zest and 3 tablespoons juice)
- 1/4 cup freshly grated Parmesan or Pecorino Romano (optional but recommended)

How to Store
For best texture, enjoy this dish fresh.
Zucchini noodles soften as they sit. If you have leftovers, store them in an airtight container in the fridge for up to 2 days. Reheat gently in a skillet over low heat just until warm.
Avoid microwaving for too long; it can overcook the shrimp and release more water from the zucchini. If you plan ahead for meal prep, keep the shrimp and sauce in one container and the raw zoodles separate, then combine and cook right before eating.
Health Benefits
- Low in carbs: Zucchini replaces pasta, keeping net carbs low while still providing volume and fiber.
- High-quality protein: Shrimp deliver lean protein and key nutrients like selenium, iodine, and vitamin B12.
- Healthy fats: Olive oil and a measured amount of butter support satiety and flavor on a keto plan.
- Antioxidants: Garlic, parsley, and lemon provide phytochemicals that support overall wellness.
- Light yet satisfying: The combination of protein, fat, and fiber helps keep you full without heaviness.
Pitfalls to Watch Out For
- Watery sauce: Skip salting/drying the zucchini and you’ll dilute the scampi sauce. Pat those zoodles dry.
- Overcooked shrimp: They cook fast.
Pull them as soon as they turn pink and curl into a loose “C.” A tight “O” means overdone.
- Too much lemon: Lemon is key, but too much can overpower the delicate shrimp. Start with the listed amount and adjust at the end.
- Burnt garlic: Garlic turns bitter quickly. Keep heat moderate and stir constantly during that first minute.
- Excess salt: If using capers, salted butter, or Parmesan, taste before adding more salt.
Alternatives
- Non-alcoholic: Use chicken broth instead of wine.
Add a splash more lemon to brighten.
- Dairy-free: Swap butter for ghee or a dairy-free butter substitute. Skip the Parmesan or use a dairy-free aged cheese alternative.
- Veggie swaps: Try shirataki noodles, spaghetti squash, or hearts of palm pasta for different textures while keeping carbs low.
- Protein variations: Use scallops, chicken tenders, or a mix of shrimp and squid. Adjust cook times accordingly.
- Herb twist: Add basil or chives with the parsley, or finish with a small pinch of lemon thyme.
- Heat level: Increase red pepper flakes or add a dab of Calabrian chili paste for bolder spice.
FAQ
Can I use frozen shrimp?
Yes.
Thaw completely in the fridge overnight or under cold running water, then pat dry very well. Excess moisture prevents a good sear and waters down the sauce.
Do I need a spiralizer?
No. Many grocery stores sell pre-spiralized zucchini.
You can also use a julienne peeler or slice zucchini into thin ribbons with a vegetable peeler and cut into strips.
How do I keep zoodles from getting soggy?
Salt and drain them first, then cook just 2–3 minutes until crisp-tender. High heat for too long releases water. If needed, remove the zoodles briefly and reduce the sauce further, then toss everything together right before serving.
What wine works best?
Choose a dry white like Sauvignon Blanc or Pinot Grigio.
Avoid sweet wines, which can clash with the lemon and garlic. If you don’t drink alcohol, broth works fine with an extra squeeze of lemon.
Is Parmesan keto-friendly?
Yes. Parmesan is low in carbs and high in flavor.
Use a light hand if tracking calories, but it’s a great finisher for scampi.
Can I make this ahead?
Prep components ahead, but cook right before serving. Spiralize and dry the zucchini, mince the garlic, and season the shrimp. Store separately, then cook in under 15 minutes when ready to eat.
What pan should I use?
A large stainless steel or nonstick skillet works well.
You want enough surface area to cook the shrimp in a single layer and toss the zoodles without crowding.
How many carbs are in this dish?
Exact numbers vary with brands and portions, but a typical serving lands around 6–8 net carbs, largely from the zucchini and lemon. Skip the wine and go with broth if you want to keep carbs as low as possible.
In Conclusion
Keto Zucchini Shrimp Scampi is fresh, fast, and big on flavor. With a buttery garlic sauce, bright lemon, and tender shrimp, it feels special without a lot of effort.
Keep the zoodles crisp, don’t overcook the shrimp, and finish with parsley and Parmesan for the perfect touch. It’s a weeknight win that fits your low-carb goals and tastes like a treat.
