These are the kinds of small details that turn a shrimp and spaghetti squash recipe into something you will want to share with everyone you know.
Chef's Tip: Do not skip drying your shrimp with paper towels. A wet shrimp will steam rather than sear, and you will miss out on that gorgeous golden crust that makes sauteed shrimp so irresistible.
Getting the right sear on shrimp and achieving perfectly roasted squash really does come down to having a good heavy-bottomed skillet and a proper rimmed baking sheet. The right equipment makes the difference between soggy squash and caramelized, flavorful strands.
Before we get into cooking, a word on selecting and storing your squash. Knowing how to preserve spaghetti squash is genuinely useful, especially if you want to meal prep or buy in bulk.
At the store, look for a squash that is firm and heavy for its size, with a pale yellow or golden rind. Avoid any with soft spots, green patches, or blemishes. A ripe spaghetti squash has no give when you press on it.
At home (uncut): A whole, uncut spaghetti squash will keep at room temperature in a cool, dry spot for up to a month, or in the refrigerator for up to three months. This makes it an incredibly pantry-friendly ingredient.
Once roasted and shredded, the strands keep in an airtight container in the refrigerator for up to three to four days, which makes them perfect for meal prepping ahead of weeknight dinners like this one.
Tip: If you find spaghetti squash hard to cut raw, pierce it a few times with a knife and microwave it for 3 to 4 minutes first. It softens the rind just enough to make slicing much safer and easier.

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.
Preheat the oven to 400 degrees F (200 degrees C). Line a large baking sheet with parchment paper.
Brush the cut sides of the spaghetti squash with 1 tablespoon of olive oil and season generously with salt and pepper. Place cut-side down on the prepared baking sheet.
Roast for 35 to 40 minutes, until the squash is tender and the strands pull apart easily with a fork. Remove from the oven and let it cool for 5 minutes.
Use a fork to scrape the squash flesh into long spaghetti-like strands. Transfer the strands to a bowl and set aside. Discard the shells or keep them for serving.
While the squash roasts, pat the shrimp completely dry with paper towels. Season with salt, pepper, and red pepper flakes.
Heat the remaining 1 tablespoon 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, just until pink and opaque. Do not overcook. Transfer 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 cook for 1 minute, stirring constantly, until fragrant.
Pour in the white wine (or chicken broth) and stir to deglaze the pan, scraping up any browned bits. Let it simmer for 2 minutes until slightly reduced.
Add the cherry tomatoes and cook for 2 to 3 minutes, until they begin to soften and burst.
Add the spaghetti squash strands to the skillet and toss everything together until well coated in the sauce. Cook for 1 to 2 minutes to heat through.
Return the shrimp to the pan. Add the lemon juice and lemon zest and toss to combine. Taste and adjust seasoning as needed.
Serve immediately, garnished with fresh parsley and Parmesan cheese if desired.
This dish is best served immediately, straight from the skillet while the shrimp are still juicy and the sauce is at its glossiest. Serve it directly in the squash shells for a stunning presentation, or pile it into wide shallow bowls.
For toppings, keep it simple: fresh parsley, a squeeze of extra lemon, and a shower of grated Parmesan if you are not strictly dairy-free. A glass of crisp white wine alongside, perhaps the same one you used in the sauce, makes this feel genuinely restaurant-worthy.
Leftovers keep for up to two days in the refrigerator and reheat best in a skillet over low heat with a small splash of broth. This is one of those shrimp with spaghetti squash recipes that proves healthy weeknight cooking does not have to mean boring or unsatisfying. Once you make it, you will find yourself coming back to it every time that pasta craving hits.
