This garlic shrimp spaghetti squash is a light, satisfying low-carb dinner packed with juicy shrimp, roasted squash strands, and a buttery garlic sauce. Ready in under an hour and naturally keto-friendly!

If you have been searching for shrimp spaghetti squash recipes that do not feel like you are settling for a sad substitute, this is the one. We are talking juicy, garlicky shrimp piled over tender, golden squash strands with a bright lemon-butter sauce that ties everything together. It looks impressive. It tastes even better. And it comes together in about an hour with very little hands-on effort.
This is the kind of weeknight dinner that earns a permanent spot in your rotation, whether you are eating low-carb, keto, gluten-free, or simply trying to get more vegetables onto your plate without anyone complaining.
Spaghetti squash is genuinely one of the most underrated vegetables in the produce aisle. Once roasted and shredded with a fork, the flesh separates into long, delicate strands that have a mild, slightly sweet flavor and a satisfying bite. Unlike zucchini noodles, squash strands hold up to a saucy topping without going limp immediately, which makes them the ideal base for shrimp and spaghetti squash.
For keto shrimp with spaghetti squash, this vegetable is a game-changer. A full cup of cooked strands contains around 7 grams of net carbs, a fraction of what traditional pasta carries. You get a generous, filling bowl of food that keeps your macros exactly where you want them.
Chef's Tip: The single biggest mistake people make with spaghetti squash is undercooking it. The strands should pull away from the shell effortlessly. If they resist or clump together, give it another 5 to 10 minutes in the oven.
The sauce in this garlic shrimp spaghetti squash recipe is simple but deeply flavorful. Butter, olive oil, a generous amount of minced garlic, cherry tomatoes, a splash of white wine, and a hit of fresh lemon juice. That combination creates a light, glossy pan sauce that coats every strand of squash and every curl of shrimp beautifully.
The cherry tomatoes are not an afterthought. They burst as they cook and release a concentrated sweetness that balances the garlic and the acidity of the lemon. Do not skip them.
For the shrimp, dry is everything. Pat each piece thoroughly with paper towels before it goes into the pan. Moisture is the enemy of a proper sear, and a good sear gives you those slightly caramelized edges that make shrimp taste like something from a restaurant.
Having the right pan matters here. A wide, heavy-bottomed skillet gives the shrimp enough room to sear rather than steam, and it holds heat evenly when you build the sauce. A sharp chef's knife makes halving a dense squash safe and easy.
Knowing how to preserve spaghetti squash starts at the store. Look for a squash that feels heavy for its size, has a firm, unblemished rind, and a dry stem. Avoid any soft spots or green patches.
Whole, uncut spaghetti squash keeps at room temperature in a cool, dry spot for up to 3 months. Once cut or cooked, store it in an airtight container in the refrigerator for up to 4 days. This makes it incredibly convenient to roast on a Sunday and use throughout the week in dishes like this one.
A few details that make a real difference:
Chef's Tip: Add a handful of fresh baby spinach or arugula to the skillet along with the shrimp at the end. It wilts in about 30 seconds and adds color, nutrition, and a peppery depth that pairs beautifully with the garlic butter sauce.
Once you have the base recipe down, this dish is endlessly adaptable:

Preheat your oven to 400 degrees F (200 degrees C). Line a large baking sheet with parchment paper.
Carefully halve the spaghetti squash lengthwise and scoop out the seeds. Brush the cut sides with 1 tablespoon of olive oil and season generously with salt and black pepper.
Place the squash cut-side down on the prepared baking sheet. Roast for 35 to 45 minutes, until the flesh is fork-tender and the strands pull away easily. Timing will vary based on the size of your squash.
While the squash roasts, pat the shrimp completely dry with paper towels. Season with 0.5 teaspoon kosher salt and a pinch of black pepper.
Heat the remaining 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium-high heat. Once the butter is foamy, add the shrimp in a single layer and cook for 1 to 2 minutes per side until pink and just cooked through. Transfer to a plate and set aside.
Reduce the heat to medium. Add the remaining 2 tablespoons butter to the same skillet. Once melted, add the minced garlic and red pepper flakes. Sauté for about 60 seconds until fragrant, stirring constantly so the garlic does not burn.
Add the halved cherry tomatoes and cook for 2 minutes until they begin to soften and release their juices.
Pour in the white wine (or chicken broth) and lemon juice. Let the sauce simmer for 2 to 3 minutes, scraping up any browned bits from the bottom of the pan.
Remove the roasted spaghetti squash from the oven. Flip each half cut-side up and use a fork to scrape the flesh into spaghetti-like strands directly in the shell.
Return the shrimp to the skillet and toss to coat in the sauce. Stir in the lemon zest and adjust seasoning with salt and pepper.
Divide the garlic shrimp mixture evenly over the squash strands in each shell, or scrape the squash strands into the skillet and toss everything together. Garnish with fresh parsley and Parmesan if desired. Serve immediately.
Serve the finished dish directly in the squash shells for a dramatic presentation, or toss everything together in the skillet and serve it family-style in a large bowl. A final shower of fresh parsley and a dusting of Parmesan (optional but highly recommended) finish it off.
Leftovers keep in the refrigerator for up to 3 days. Reheat gently in a skillet with a small splash of broth, just until warmed through. Shrimp and spaghetti squash recipes like this one actually reheat better than most pasta dishes because the squash does not absorb the sauce the way pasta does, so the strands stay distinct and the sauce redistributes beautifully.
Whether this is your first time cooking with spaghetti squash or your hundredth, this garlic shrimp spaghetti squash recipe is one you will come back to again and again.
