This garlic shrimp spaghetti squash is a light, satisfying low-carb dinner packed with juicy shrimp, roasted squash strands, and a buttery garlic sauce that comes together in under an hour.

If you have ever stood in the kitchen craving a big bowl of garlicky, buttery pasta but wanted something that would not derail your healthy eating, this garlic shrimp spaghetti squash is your answer. It has everything you love about a classic shrimp scampi, which is the glossy sauce, the fragrant garlic, the bright hit of lemon, but swapped onto tender roasted squash strands instead of noodles. The result is lighter, naturally gluten-free, and genuinely satisfying in a way that actually surprises people the first time they try it.
This is one of those shrimp and spaghetti squash recipes that earns a permanent spot in your weeknight rotation. It looks and tastes impressive enough for guests, but the hands-on time is minimal once the squash is in the oven.
Spaghetti squash has a mild, slightly sweet flavor that plays beautifully with bold, savory sauces. Unlike zucchini noodles, which can release a lot of water, roasted spaghetti squash strands hold up well in a pan without turning your sauce into a puddle. The key is roasting the squash cut-side down so the edges caramelize slightly and the interior steams into perfectly separated strands.
When you fork those golden strands into a skillet with garlic butter, white wine, and fresh parmesan, they soak up every bit of that sauce. The shrimp finish in minutes, so everything comes together while the squash is still warm. This is exactly what a great spaghetti squash with shrimp recipe should feel like, fast, cohesive, and deeply flavorful.
Chef's Tip: Always pat your shrimp very dry before they go into the pan. Moisture is the enemy of a good sear. Dry shrimp get beautifully pink and slightly caramelized on the outside rather than steaming in their own liquid.
For a recipe this simple, quality really does make a difference. A wide, heavy skillet gives the shrimp enough room to sear properly without crowding, and a sharp knife makes halving that dense squash much safer and easier. Using good olive oil and freshly grated parmesan rather than the pre-shredded kind will noticeably elevate the final sauce.
One of the great things about this recipe is how well it lends itself to meal prep. Knowing how to preserve spaghetti squash properly can save you serious time on busy weeknights.
Whole uncooked squash will keep at room temperature in a cool, dry spot for up to a month, which makes it a great pantry staple to keep on hand.
After roasting, scraped spaghetti squash strands store beautifully in an airtight container in the refrigerator for up to 3 to 4 days. You can roast two squash at once on a Sunday and use the strands across multiple meals throughout the week. Pair one batch with this garlic shrimp recipe and use the rest in a quick grain bowl or topped with marinara for a meatless meal.
Cooked shrimp and spaghetti squash together will last about 2 days in the fridge. For best results, reheat in a skillet over low heat with a tiny splash of broth rather than the microwave.
If you are following a low-carb or ketogenic diet, this dish was practically designed for you. Keto shrimp with spaghetti squash checks all the boxes: high protein from the shrimp, healthy fats from olive oil and butter, and very moderate carbohydrates from the squash. One serving comes in at roughly 310 calories with 28 grams of protein and only 18 grams of carbs, most of which come with 4 grams of fiber.
Skip the wine and use chicken broth instead if you want to keep the carb count even lower. The flavor will be slightly more savory but just as delicious.
Once you have the base recipe down, this dish is wonderfully flexible. Here are a few easy directions to take it:
Chef's Tip: Do not overcook the garlic. It should smell fragrant and turn just barely golden, about 60 seconds. Burnt garlic will make the entire sauce taste bitter, and there is no coming back from that.

This garlic shrimp spaghetti squash is a light, satisfying low-carb dinner packed with juicy shrimp, roasted squash strands, and a buttery garlic sauce that comes together in under an hour.
Preheat your oven to 400 degrees F (200 degrees C). Line a large baking sheet with parchment paper.
Carefully cut the spaghetti squash in half lengthwise and scoop out the seeds. Brush the cut sides with 1 tablespoon of olive oil and season with 0.5 teaspoon salt and a few cracks of black pepper.
Place the squash cut-side down on the prepared baking sheet. Roast for 35 to 40 minutes, until the flesh is tender and easily pulls into strands with a fork.
While the squash roasts, pat the shrimp completely dry with paper towels and season with the remaining 0.5 teaspoon salt and black pepper.
Heat the remaining 2 tablespoons of olive oil in a large skillet over medium-high heat. Add the shrimp in a single layer and cook for 1 to 2 minutes per side until pink and just cooked through. Transfer the shrimp to a plate and set aside.
Reduce the heat to medium. Add the butter to the same skillet. Once melted, add the minced garlic and red pepper flakes. Cook, stirring constantly, for about 1 minute until fragrant and lightly golden.
Pour in the white wine (or broth) and let it simmer for 2 minutes, scraping up any browned bits from the bottom of the pan.
Remove the roasted spaghetti squash from the oven and let it cool for 5 minutes. Use a fork to scrape the flesh into long noodle-like strands directly into the skillet.
Add the lemon zest, lemon juice, and parmesan to the skillet. Toss everything together over medium-low heat until the squash strands are evenly coated in the sauce.
Return the cooked shrimp to the skillet and fold them in gently. Taste and adjust seasoning as needed.
Divide among bowls, top with fresh parsley and extra parmesan, and serve immediately.
This dish is a complete meal on its own, but a few simple additions can round it out nicely. A crisp green salad with a lemony vinaigrette mirrors the bright flavors in the shrimp sauce perfectly. A glass of the same dry white wine you used in the recipe makes a natural pairing. If you are feeding a crowd that wants something more substantial, a slice of crusty sourdough for soaking up the sauce is always welcome, even if it breaks the low-carb rules for a night.
However you serve it, garlic shrimp spaghetti squash is the kind of dinner that feels like a treat while still being genuinely good for you. And in this household, that is always worth celebrating.
