Why You’ll Love Shrimp Scampi Spaghetti Squash Recipe

I appreciate how this recipe balances indulgence and freshness so well. The spaghetti squash creates a tender, noodle-like base without the heaviness of pasta, while the shrimp adds a juicy, protein-packed bite. I also enjoy how the garlic, lemon, and bright, tangy liquid come together to form a flavorful sauce that tastes restaurant-quality. It’s a great option when I want something wholesome that still feels special.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

1 (2 1/2 – 3 lb.) spaghetti squash
Cooking spray
1 tsp. kosher, salt, divided
5 garlic cloves 2 grated, 3 minced
4 Tbsp. extra-virgin olive oil, divided
1 lb. large raw shrimp, peeled and deveined
1/2 cup finely chopped shallots
1/4-1/2 tsp. red pepper flakes (1/4 tsp. for mild heat; 1/2 tsp. for medium)
1/3 cup vegetable broth mixed with 1 Tbsp. white vinegar
Juice of 1/2 lemon
3 Tbsp. unsalted butter (preferably grass-fed)
3 Tbsp. finely chopped fresh parsley, divided
Cracked black pepper for garnish

Directions

I start by preheating the oven to 375ºF. Then I slice the spaghetti squash horizontally into 1 1/2 inch rings and use a spoon to scrape out the seeds and stringy parts. I place the rings on a baking sheet, lightly coat them with cooking spray, and season with 1/4 tsp. salt before baking for about 40 minutes.

Once the squash is done, I let it cool slightly, then cut through the outer edge of each ring so I can gently pull apart the strands. I use my fingers or a fork to scrape them out and arrange them on a platter.

While the squash roasts, I prepare the shrimp marinade by grating 2 garlic cloves into a bowl and mixing them with 1 Tbsp. olive oil, 1/4 tsp. salt, and the shrimp. I toss everything together and refrigerate it for about 30 minutes.

Next, I heat 2 Tbsp. olive oil in a large skillet over medium heat. I add the shrimp and cook them for about 2 minutes per side until just cooked through, then transfer them to a plate.

In the same skillet, I add the remaining 1 Tbsp. oil along with the shallots, minced garlic, and red pepper flakes. I cook this mixture for 2 to 3 minutes until fragrant. Then I pour in the prepared liquid and lemon juice, letting it reduce by half over about 2 minutes.

I stir in the butter and continue cooking until it melts and the sauce slightly thickens, about 3 to 5 minutes. Then I return the shrimp to the pan, add 1 Tbsp. parsley, and toss everything together for another minute.

Finally, I spoon the shrimp scampi mixture over the spaghetti squash strands and finish with the remaining parsley and a sprinkle of cracked black pepper.

Servings and Timing

I prepare this recipe to serve 4 people. The prep time takes about 15 minutes, while the cooking time is around 45 minutes, making the total time approximately 1 hour.

Variations

I sometimes swap shrimp for scallops or even chicken when I want a different protein. For a dairy-free version, I replace the butter with a plant-based alternative. If I want a more vegetable-forward dish, I add spinach or cherry tomatoes to the skillet. I also like increasing the red pepper flakes when I’m in the mood for extra heat.

Storage/Reheating

I store leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, I use the microwave and stir every 30 seconds until warmed through. Alternatively, I reheat it in a skillet over medium heat, adding a splash of broth if needed to keep everything moist and flavorful.
