Ingredients
Method
- Prep the zoodles. Spiralize the zucchini, then place the zoodles on a clean kitchen towel. Lightly salt and let sit 10 minutes to draw out moisture. Gently squeeze to remove excess water. This step keeps the dish from getting watery.
- Pat the shrimp dry. Use paper towels to remove moisture. Season with salt and pepper. Dry shrimp sear better and won’t steam.
- Heat the pan. In a large skillet over medium-high heat, warm the olive oil and 2 tablespoons of the butter until the butter foams.
- Sear the shrimp. Add the shrimp in a single layer. Cook 1–2 minutes per side until pink and just opaque. Don’t overcrowd; do two batches if needed. Transfer shrimp to a plate.
- Make the garlic butter. Reduce heat to medium. Add the remaining 2 tablespoons butter to the skillet. Stir in the minced garlic and red pepper flakes (if using). Cook 30–45 seconds, just until fragrant—don’t brown the garlic.
- Deglaze with lemon. Add lemon zest and juice. Scrape up any browned bits from the pan for extra flavor. Taste and season with salt and pepper as needed.
- Toss in the zoodles. Add the zoodles to the pan and toss for 1–2 minutes until just tender but still crisp. You want them al dente—overcooking leads to soggy noodles.
- Return the shrimp. Add shrimp and any juices from the plate. Toss to coat in the sauce. Warm through for 30–60 seconds.
- Finish and serve. Remove from heat. Stir in chopped parsley. Garnish with Parmesan and extra lemon wedges if you like. Serve immediately.
Why This Recipe Works
Shrimp cooks fast, so you get a high-protein meal on the table in minutes. Zoodles (zucchini noodles) bring the texture of pasta without the carbs, and they soak up all that garlicky butter like a sponge. Lemon and parsley brighten everything so the dish tastes balanced, not heavy.
Best of all, the pan sauce is simple: butter, olive oil, garlic, and a splash of lemon. It’s the kind of basic you’ll make on repeat.
What You’ll Need
- Large shrimp (about 1 to 1.25 pounds), peeled and deveined, tails on or off
- Zucchini (3 medium), spiralized into zoodles
- Unsalted butter (4 tablespoons)
- Olive oil (1 tablespoon)
- Garlic (4–5 cloves), finely minced
- Lemon (1), zest and juice
- Crushed red pepper flakes (optional, 1/4 teaspoon)
- Fresh parsley (2–3 tablespoons), chopped
- Sea salt and black pepper, to taste
- Grated Parmesan (optional, for serving)
- Extra lemon wedges (optional, for serving)

How to Store
For best texture, eat this dish fresh.
Zoodles release water as they sit, which can thin the sauce. If you have leftovers, store them in an airtight container in the fridge for up to 2 days. Reheat gently in a skillet over medium-low heat just until warm.
Avoid the microwave if possible—it can turn the shrimp rubbery and the zoodles mushy. If the sauce gets watery, add a small pat of butter and a squeeze of lemon to revive it.
Benefits of This Recipe
- Low-carb and keto-friendly: Zoodles keep net carbs down while adding fiber and volume.
- High in protein: Shrimp delivers a lean protein punch with minimal calories.
- Quick and easy: From prep to plate in about 20 minutes.
- Simple ingredients: Pantry staples like butter, garlic, and lemon build big flavor.
- Light but satisfying: Rich sauce balances with fresh zucchini and herbs.
Pitfalls to Watch Out For
- Overcooking shrimp: They turn tough quickly. Pull them as soon as they’re pink and curled into a loose “C.” A tight “O” means overdone.
- Soggy zoodles: Skip the squeeze step and you’ll have a watery pan.
Cook zoodles briefly over medium heat, not high, to keep them crisp.
- Burning garlic: Garlic can go from fragrant to bitter in seconds. Lower the heat and stir constantly when it hits the pan.
- Overcrowding the pan: Too many shrimp at once leads to steaming instead of searing. Work in batches if needed.
- Under-seasoning: Salt enhances every element here.
Taste the sauce before adding zoodles and adjust.
Variations You Can Try
- Cajun kick: Toss shrimp with 1–2 teaspoons Cajun seasoning before searing. Balance with extra lemon.
- Creamy upgrade: Stir in 2–3 tablespoons heavy cream or mascarpone to the sauce after the garlic for a silky finish.
- Herb swap: Try basil, dill, or chives instead of parsley. Each gives a different fresh note.
- Add veggies: Sauté halved cherry tomatoes, baby spinach, or sliced mushrooms before the garlic.
Keep it low-carb and colorful.
- Nutty finish: Toasted pine nuts or slivered almonds add crunch without many carbs.
- Spiral mix: Combine zucchini with spiralized yellow squash for more color and sweetness.
- Ghee or clarified butter: For a higher smoke point and a richer, toasty flavor, swap the butter with ghee.
FAQ
Can I use frozen shrimp?
Yes. Thaw them fully in the fridge overnight or under cold running water for 10–15 minutes. Pat them very dry before cooking to get a good sear and avoid excess water in the pan.
How do I make zoodles without a spiralizer?
Use a julienne peeler for thin strips or a standard vegetable peeler for wider ribbons.
You can also buy pre-spiralized zucchini from many grocery stores for convenience.
Is this recipe spicy?
Only if you add red pepper flakes. They’re optional and easy to adjust. Start with a pinch and build to your heat preference.
How can I keep the sauce from getting watery?
Salt and squeeze the zoodles first, and don’t overcook them.
Also, cook the shrimp in batches to avoid steaming. If needed, let the sauce bubble for 30 seconds before adding zoodles to thicken slightly, then remove from heat quickly.
What can I use instead of zucchini?
Try spiralized yellow squash, cucumber (served raw and tossed at the end), or hearts of palm noodles. For a non-spiral option, sauté shredded cabbage for a low-carb “noodle” vibe.
Can I make this dairy-free?
Yes.
Use olive oil and a dairy-free butter alternative or ghee if tolerated. The flavor will still be rich, but you may want to add a touch more lemon for brightness.
What protein alternatives work here?
Scallops, chunks of firm white fish (like cod), or chicken tenders all work. Adjust cook times: scallops need 1–2 minutes per side, fish 2–3 minutes, and chicken 3–4 minutes per side depending on thickness.
Is Parmesan keto-friendly?
Yes, Parmesan is low in carbs and high in flavor.
Use it sparingly if you’re tracking calories or sodium, but it fits well in most keto plans.
How many carbs are in this dish?
Exact counts vary with portion size and ingredients, but a typical serving is about 6–8 net carbs, mainly from the zucchini and lemon. Check specific brands and amounts if you need precise macros.
Can I meal prep this?
You can prep components: spiralize and salt zucchini ahead, mince garlic, and clean the shrimp. Cook just before serving for the best texture.
If storing, keep shrimp and zoodles separate and combine when reheating.
