Why You Will Love This Recipe
Let's be honest, spaghetti squash gets a bad reputation as a sad pasta substitute. But prepared the right way, it is genuinely delicious and not just a consolation prize. The key is roasting it properly so the strands develop a light caramelized flavor, then pairing it with a sauce bold enough to shine.
Here is why this shrimp with spaghetti squash recipe works so well:
- Big garlic flavor. Six cloves of minced garlic bloomed in brown butter creates a sauce that is fragrant, savory, and deeply satisfying.
- Quick-cooking protein. Shrimp go from raw to perfect in about 3 minutes, which keeps this dinner fast.
- Naturally keto-friendly. This dish is a go-to for keto shrimp with spaghetti squash, with around 18 grams of net carbs per generous serving.
- Weeknight practical. You can roast the squash up to 3 days ahead, which makes the actual dinner prep incredibly fast.
Tips for Choosing and Preserving Spaghetti Squash
If you are wondering how to preserve spaghetti squash for future meals, here is what you need to know. A whole, uncut spaghetti squash stores beautifully at room temperature in a cool, dry place for up to 3 months, making it a pantry hero. Once cut and roasted, the scraped strands keep in the fridge in an airtight container for up to 5 days.
When picking a squash at the store, look for one that feels heavy for its size with a firm, blemish-free skin and a dry, intact stem. Avoid any with soft spots or a greenish tinge, as those tend to be underripe.
Chef's Tip: Always roast spaghetti squash cut-side down on the baking sheet. This traps steam inside and creates much more tender strands than roasting cut-side up. It also encourages a little caramelization on the flesh that adds real depth of flavor.
Getting the Shrimp Right
The biggest mistake people make with shrimp is not drying them before cooking. Wet shrimp steam instead of sear, and you lose that beautiful golden crust and concentrated flavor. Pat them thoroughly with paper towels, season them just before they hit the pan, and cook them in a single layer over high heat.
For shrimp and spaghetti squash recipes, a large, wide skillet is your best friend. You want maximum surface area so the shrimp can sear rather than crowd. A 12-inch stainless steel or cast iron skillet gives you the best results.
Using quality ingredients makes a noticeable difference in a simple dish like this, from good butter to fresh garlic and a decent dry white wine for the pan sauce.
Building the Garlic Butter Sauce
This is truly one of the simplest pan sauces you will ever make, and it delivers enormous flavor. After the shrimp come out of the pan, you build the sauce right in the same skillet using the flavorful browned bits left behind.
Garlic goes in first, just long enough to turn fragrant and golden at the edges. Then white wine hits the pan (or chicken broth if you prefer), deglazing all that goodness and reducing into a silky, bright sauce. A finish of lemon juice and zest lifts everything and keeps the dish feeling fresh rather than heavy.
Once the spaghetti squash strands go in, they soak up the sauce beautifully. The whole skillet becomes something that genuinely rivals a bowl of pasta.
Chef's Tip: Pull your shrimp off the heat while they are just barely opaque in the center. They will continue to cook slightly from residual heat when you add them back to the warm sauce. Overcooked shrimp are the number one thing that takes this dish from great to just okay.

Garlic Shrimp Spaghetti Squash (Easy, Low-Carb & Incredibly Satisfying)
This garlic shrimp spaghetti squash recipe is a light, low-carb dinner packed with bold flavor. Tender roasted squash strands tossed with juicy shrimp in a garlicky butter sauce — ready in under an hour.
Ingredients
- 1 spaghetti squash, about 3 lbs, halved and seeds removed
- 1 1/4 lbs large shrimp, peeled, deveined, tails removed
- 3 tbsp unsalted butter, divided
- 2 tbsp olive oil, extra virgin
- 6 garlic cloves, minced
- 3/8 cup dry white wine, or chicken broth as substitute
- 1 lemon, zested and juiced
- 1/2 tsp crushed red pepper flakes, adjust to taste
- 1 tsp kosher salt, plus more to taste
- 1/2 tsp black pepper, freshly ground
- 1/4 cup fresh parsley, roughly chopped, for garnish
- 3/8 cup Parmesan cheese, freshly grated, optional for serving
Instruction
Preheat your oven to 400 degrees F (200 degrees C). Line a large baking sheet with parchment paper or foil.
Carefully halve the spaghetti squash lengthwise and scoop out the seeds with a spoon. Brush the cut sides with 1 tablespoon of olive oil and season generously with salt and pepper.
Place the squash cut-side down on the prepared baking sheet. Roast for 35 to 45 minutes, until the flesh is easily pierced with a fork and the strands pull away cleanly.
While the squash roasts, pat the shrimp completely dry with paper towels. Season with salt, pepper, and a pinch of red pepper flakes.
About 10 minutes before the squash finishes, heat the remaining 1 tablespoon of olive oil and 1 tablespoon of butter in a large skillet over medium-high heat.
Add the shrimp in a single layer. Cook for 1 to 2 minutes per side, until pink and just opaque. Do not overcook. Transfer the shrimp to a plate and set aside.
Reduce the heat to medium and add the remaining 2 tablespoons of butter to the same skillet. Add the minced garlic and saute for 60 seconds until fragrant but not browned.
Pour in the white wine (or chicken broth) and lemon juice. Let it simmer for 2 to 3 minutes, scraping up any browned bits from the bottom of the pan, until slightly reduced.
Remove the roasted squash from the oven. Using a fork, scrape the flesh into spaghetti-like strands directly in the shell, or transfer to a large bowl.
Add the spaghetti squash strands to the skillet. Toss to coat in the garlic butter sauce. Return the cooked shrimp to the skillet, add the lemon zest, and toss everything together gently.
Taste and adjust salt, pepper, and lemon juice as needed. Divide among plates and garnish with fresh parsley and grated Parmesan if desired. Serve immediately.

Notes
Serving Ideas and Variations
This dish is complete as-is, but here are a few ways to make it your own:
- Add greens. Stir a few handfuls of baby spinach or arugula into the skillet right before serving. They wilt beautifully in the warm sauce.
- Make it creamy. Stir a few tablespoons of heavy cream into the garlic sauce after the wine reduces for a richer, more indulgent version.
- Add heat. Double the red pepper flakes, or finish with a drizzle of chili oil for a spicy kick.
- Go dairy-free. Swap the butter for additional olive oil and skip the Parmesan. The dish is still deeply flavorful.
Whether you are cooking for a low-carb dinner party, meal prepping for the week, or just looking for a lighter take on a pasta night, spaghetti squash with shrimp truly delivers. It is the kind of recipe that earns a permanent spot in your weekly lineup.
