This Shrimp Scampi Spaghetti Squash Recipe relies on straightforward ingredients that come together harmoniously to deliver a dish full of bold flavor, delicate textures, and eye-catching color. Each component plays a vital role, from the garlicky shrimp to the fresh parsley garnish, making the preparation feel approachable and rewarding.

Spaghetti squash (2½ to 3 lb.): The star vegetable that serves as a wholesome, noodle-like base with a mild, slightly sweet flavor.

Cooking spray: For lightly coating the squash rings before baking to promote even roasting and prevent sticking.
Kosher salt, 1 tsp. divided: To season both the squash and the shrimp for balanced seasoning throughout.
Garlic cloves (5 total – 2 grated, 3 minced): Infuses the shrimp and sauce with a rich, aromatic garlic punch.

Extra-virgin olive oil (4 Tbsp. divided): Adds fruity depth and helps sauté the shrimp and aromatics beautifully.
Large raw shrimp (1 lb., peeled and deveined): Tender and juicy, the main protein that carries the scampi flavor.
Finely chopped shallots (½ cup): Brings a gentle sweetness and subtle onion undertone to the sauce.

Red pepper flakes (¼–½ tsp.): Offers a customizable touch of spicy heat, from mild to medium.
Vegetable broth (5 Tbsp.) mixed with white vinegar (1 Tbsp.): Adds acidity and moisture, helping to create a flavorful sauce reduction.
Lemon juice (from ½ lemon): Brightens the dish with refreshing citrus notes.

Unsalted butter (3 Tbsp.): Enriches the sauce with creamy, silky goodness; grass-fed is a bonus for flavor.
Fresh parsley (3 Tbsp. finely chopped, divided): Finishes the dish with herby freshness and a lively pop of green.
Cracked black pepper: A final seasoning touch to enhance the overall flavor profile.

How to Make Shrimp Scampi Spaghetti Squash Recipe

Step 1: Roast the Spaghetti Squash

Begin by preheating your oven to 375°F. Slice the spaghetti squash horizontally into 1½-inch thick rings—a shape that allows even roasting and easy seed removal. Use a large spoon to scoop out the seeds and stringy membranes, then arrange the rings on a rimmed baking sheet. Lightly spritz with cooking spray and sprinkle with ¼ teaspoon kosher salt. Roast for about 40 minutes until the flesh is tender and easily pierced with a fork, setting the stage for that perfect spaghetti texture.

Step 2: Prepare the Shrimp Marinade

While the squash bakes, make your shrimp sing by mixing the grated garlic with olive oil and a pinch of salt. Toss the peeled and deveined shrimp in this fragrant marinade, then pop it into the fridge for a quick 30-minute flavor boost. This step infuses the shrimp with garlic goodness and ensures every bite is bursting with taste.

Step 3: Cook the Shrimp

Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the shrimp along with the marinade and cook them for about 2 minutes per side or until they turn an inviting opaque pink. This quick sear locks in juiciness and preserves that tender texture. Once cooked, transfer the shrimp to a plate and set aside to keep warm.

Step 4: Create the Scampi Sauce

In the same skillet, add the remaining tablespoon of olive oil along with finely chopped shallots, minced garlic, and red pepper flakes. Sauté for 2 to 3 minutes, stirring often, until the shallots soften and the kitchen fills with a fragrant aroma. Pour in your vegetable broth mixed with white vinegar and lemon juice, letting it simmer until reduced by half. Swirl in the butter, cooking gently until the sauce thickens slightly into a luscious finish.

Step 5: Combine and Serve

Return the cooked shrimp to the skillet and toss in 1 tablespoon of fresh parsley. Stir everything together, coating the shrimp in that velvety sauce, and warm it through for another minute. Meanwhile, gently pry open each roasted spaghetti squash ring to reveal the delicate strands. Use a fork or your fingers to scrape out the strands and pile them onto your serving platter. Spoon the shrimp scampi and sauce over the squash strands, then sprinkle with the remaining parsley and a crack of black pepper for that final touch of beauty and flavor.

How to Serve Shrimp Scampi Spaghetti Squash Recipe

Scattered diced onions and bits of green herbs are sprinkled over the dish, adding texture and color contrast. The shrimp have a shiny, lightly coated look from the sauce or oil. The plate sits on a white marbled surface next to a bowl with fresh green chopped herbs and a small white plate holding lemon wedges. The photo was taken with an iphone --ar 4:5 --v 7

Garnishes

Fresh herbs like parsley not only add a vibrant splash of green but also brighten the flavors with their natural freshness. A sprinkle of cracked black pepper adds a visually appealing contrast and a subtle spice boost. Don’t be shy to add a thin lemon wedge on the side for guests who love an extra hint of citrus zing.

Side Dishes

This Shrimp Scampi Spaghetti Squash Recipe pairs wonderfully with crisp green salads, such as a simple arugula tossed with lemon vinaigrette, or roasted vegetables like asparagus. For a more casual meal, consider crusty bread to soak up every luscious drop of scampi sauce, making every bite unforgettable.

Creative Ways to Present

To elevate the presentation, serve the scampi directly inside the hollowed-out spaghetti squash shells for a rustic flair that’s sure to impress. Alternatively, plate the strands twirled like traditional pasta nests topped with the shrimp and drizzled with extra sauce. Or serve family-style in a large bowl for a warm, convivial dinner experience.

Make Ahead and Storage

Storing Leftovers

Any leftover shrimp scampi and spaghetti squash can be stored in an airtight container in the refrigerator for up to 3 days. This recipe holds its flavor beautifully, but it’s best to keep the shrimp and squash together to allow the sauce to meld into the strands and keep everything moist and tasty.

Freezing

For longer storage, you can freeze the cooked shrimp and sauce separately from the spaghetti squash strands. Freeze each in airtight containers for up to 2 months. When ready to enjoy, thaw overnight in the fridge to maintain texture and flavor integrity.

Reheating

Reheat leftovers gently in a skillet over low to medium heat, stirring occasionally to prevent the shrimp from becoming rubbery and the squash from drying out. You can splash a little broth or olive oil if the dish seems dry. Avoid microwaving if possible, as slow reheating preserves the tender textures best.

FAQs

Can I use frozen shrimp for this recipe?

Absolutely! Just be sure to thaw the shrimp completely and pat them dry before marinating to ensure they cook evenly and the marinade clings well.

What if I don’t have vegetable broth for the sauce?

You can substitute with chicken broth or even a splash of dry white wine for a similar depth of flavor, adjusting the seasoning accordingly.

How do I know when the spaghetti squash is done roasting?

The flesh should be tender enough to pierce easily with a fork and the strands should separate easily when scraped; if it feels firm, give it more time in the oven.

Can I prepare parts of this recipe ahead of time?

Yes! Roasting the spaghetti squash earlier in the day works great, as does marinating the shrimp. Just cook the shrimp and assemble the dish shortly before serving for the best texture.

Is this dish gluten-free?

Definitely. Using spaghetti squash instead of traditional pasta makes this recipe naturally gluten-free, making it ideal for those with gluten sensitivities or anyone looking to reduce carbs.
