How to Make Pesto Spaghetti Squash with Grilled Shrimp and Asparagus Recipe

Step 1: Roast the Spaghetti Squash

Cut the spaghetti squash in half lengthwise, scoop out the seeds, and poke the flesh with a fork to help it steam evenly. Season the inside with salt and tuck a tablespoon of butter into each half. Baking the squash at 425°F for about 40 minutes transforms it into tender, noodle-like strands that are perfect for soaking up flavors.

Step 2: Marinate the Shrimp

While the squash roasts, toss the shrimp in a simple marinade of olive oil, lemon juice, salt, and pepper. Let them sit in the fridge for about 10 minutes. This brief soak infuses the shrimp with bright citrus notes and seasoning, making each bite flavorful and juicy.

Step 3: Grill the Shrimp and Asparagus

Preheat your grill or oven to high, then grill the marinated shrimp alongside asparagus drizzled with olive oil and sprinkled with salt and pepper. About 10 minutes on the heat will give you beautifully charred shrimp and tender-crisp asparagus packed with smoky, fresh flavor.

Step 4: Shred and Toss the Spaghetti Squash

When your spaghetti squash is ready, scrape the flesh with a fork to create those famous strands. Stir in a generous tablespoon of pesto and fresh Parmesan cheese while the strands are still warm, allowing everything to melt together into a creamy, herb-infused base.

Step 5: Assemble and Serve

Chop the grilled shrimp and asparagus into bite-sized pieces and scatter them on top of the pesto-coated spaghetti squash. Finish by sprinkling sliced cherry tomatoes over the dish to add a fresh, vibrant pop that ties together all the wonderful flavors.

Garnishes

To elevate this dish even further, sprinkle freshly chopped basil or parsley on top, and a light drizzle of extra virgin olive oil. A small handful of toasted pine nuts adds a delightful crunch and nutty component that complements the pesto beautifully.

Side Dishes

This Pesto Spaghetti Squash with Grilled Shrimp and Asparagus Recipe is fantastic as a complete meal, but pairing it alongside a crisp green salad or some warm, crusty bread can offer extra texture and balance. A light white wine, such as Sauvignon Blanc, will also highlight the lemon and herb notes perfectly.

Creative Ways to Present

For a charming presentation, serve the spaghetti squash strands directly in the roasted squash shells—this makes for an impressive, rustic centerpiece. Alternatively, plating the dish on a large platter with shrimp and asparagus artfully arranged allows everyone to dig in family-style, sharing the vibrant colors and flavors.

Make Ahead and Storage

Storing Leftovers

This dish stores wonderfully in an airtight container in the refrigerator for up to 3 days. Keep the pesto-coated squash and grilled shrimp and vegetables together for convenience, but if you want to maintain crispness, store asparagus separately if possible.

Freezing

While fresh is best for this recipe, you can freeze portions of the roasted spaghetti squash without pesto and shrimp for up to 3 months. Avoid freezing the grilled shrimp and asparagus as their texture may suffer, but they can be remade fresh quickly when needed.

Reheating

Gently reheat leftovers in a skillet over medium-low heat, stirring occasionally until warmed through. This method keeps the shrimp juicy and prevents the squash from becoming too mushy. Add a splash of olive oil or lemon juice if it seems dry.

FAQs

Can I use pre-made pesto for this recipe?

Absolutely! Using store-bought pesto is a great shortcut that still delivers fantastic flavor. Just make sure to choose a high-quality pesto with fresh basil and good olive oil for the best taste.

Is spaghetti squash a good substitute for pasta?

Yes, spaghetti squash is a wonderful low-carb, gluten-free alternative to traditional pasta. It has a mild flavor and a slightly crunchy texture that pairs beautifully with sauces like pesto.

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

The squash is ready when the flesh is fork-tender and strands easily separate with a fork. Typically, this takes around 40 minutes at 425°F, but check periodically to avoid overcooking.

Can I grill the shrimp and asparagus indoors?

Definitely! If you don’t have an outdoor grill, use a grill pan or broiler indoors to achieve similar results. Just be sure to watch closely to prevent burning and ensure even cooking.

What can I substitute if I don’t like asparagus?

You can swap asparagus for green beans, broccoli, or zucchini for a different veggie note. Just adjust the grilling time so your chosen vegetable is tender but still crisp.
