To make a delicious spaghetti squash with pesto, you will need the following ingredients:

Spaghetti squash

Spaghetti squash is the star of this recipe. Its unique texture makes it a great substitute for traditional pasta. You can find spaghetti squash in most grocery stores or even grow your own if you have the space!

Fresh basil

Fresh basil is essential for making a flavorful pesto sauce. The vibrant green leaves add a fresh and aromatic element to the dish. You can typically find fresh basil in the produce section of your local grocery store.

Garlic cloves

Garlic cloves provide a rich and savory flavor to the pesto sauce. Make sure to use fresh garlic cloves for the best taste. You can find them in the produce section or even at farmers’ markets.

Pine nuts

Pine nuts add a delightful nutty flavor and a creamy texture to the pesto sauce. They are a key ingredient in traditional pesto recipes. You can find pine nuts in the nuts and seeds section of the grocery store.

Parmesan cheese

Parmesan cheese adds a salty and tangy taste to the dish, enhancing the overall flavor profile. Make sure to use freshly grated Parmesan cheese for the best results. You can find it in the cheese section of your grocery store.

Olive oil

Olive oil is crucial for creating a smooth and creamy pesto sauce. It adds richness to the dish and helps bind the ingredients together. You can find olive oil in the oil section of your local grocery store.


Salt is a must for seasoning the dish. It enhances the natural flavors of the ingredients and balances out the taste. You can use sea salt or regular table salt according to your preference.

Black pepper

Black pepper adds a subtle kick and complexity to the dish. It elevates the overall taste and complements the other ingredients. You can use freshly ground black pepper for the best flavor.


Before diving into the cooking process, there are two main steps in the preparation: roasting the spaghetti squash and making the pesto sauce.

Roasting the Spaghetti Squash

Cutting and seeding the squash

Start by cutting the spaghetti squash in half lengthwise. Be sure to use a sharp knife and caution as the squash can be quite tough. Once the squash is halved, scoop out the seeds and discard them. This step is similar to cleaning out a pumpkin before carving it.

Roasting the squash in the oven

Preheat your oven to 400°F (200°C). Place the spaghetti squash halves cut-side down on a baking sheet lined with parchment paper. Roast them in the preheated oven for about 40-45 minutes or until the flesh is fork-tender.

Making the Pesto Sauce

Gathering the ingredients

To make the pesto sauce, gather the fresh basil leaves, garlic cloves, pine nuts, grated Parmesan cheese, olive oil, salt, and black pepper. Having all the ingredients ready will make the process smoother and ensure you don’t miss anything.

Blending the ingredients

In a food processor or blender, combine the fresh basil leaves, garlic cloves, pine nuts, grated Parmesan cheese, olive oil, salt, and black pepper. Blend until smooth and well combined. You may need to scrape down the sides of the blender or food processor to ensure all the ingredients are fully incorporated.

Cooking the Spaghetti Squash

Separating the strands

Once the roasted spaghetti squash has cooled slightly, use a fork to gently scrape the flesh. This will separate the strands, which resemble spaghetti noodles. Continue scraping until you have removed all the spaghetti squash strands from both halves.

Sautéing the squash strands

In a large skillet, heat a drizzle of olive oil over medium heat. Add the spaghetti squash strands to the skillet and sauté for a few minutes until they are heated through. Be careful not to overcook them, as they can become mushy.

Combining the Pesto and Squash

Mixing the pesto with the squash strands

Transfer the sautéed spaghetti squash strands to a bowl and add the desired amount of pesto sauce. Toss gently to coat the strands evenly with the pesto. The pesto will add a burst of flavor to the mild taste of the spaghetti squash.

Heating and serving the dish

If needed, you can heat the combined pesto and squash in the skillet for a minute or two, just until warmed through. Once heated, serve the spaghetti squash with pesto immediately. You can garnish it with additional grated Parmesan cheese and fresh basil leaves for extra flavor and visual appeal.

Tips and Variations

Variation: Adding protein

To make this dish more filling or add a protein element, consider adding grilled chicken, cooked shrimp, or sautéed mushrooms. These additions will complement the flavors of the spaghetti squash and pesto, creating a well-rounded meal.

Tips for perfect roasting

When roasting the spaghetti squash, make sure to evenly distribute the heat by placing the halves cut-side down on the baking sheet. This will ensure that the flesh cooks through evenly and you get perfectly roasted squash strands.

Tips for delicious pesto

To achieve a vibrant and flavorful pesto sauce, use fresh basil leaves and high-quality Parmesan cheese. The freshness of the basil leaves will greatly impact the taste of the pesto. Additionally, freshly grated Parmesan cheese will have a stronger and more pronounced flavor compared to pre-packaged varieties.

Enjoy your low-carb, delicious spaghetti squash with pesto! This dish is not only flavorful but also a healthier alternative to traditional pasta. So go ahead, grab a fork, and savor each bite of this delightful and satisfying dish. Happy cooking!
