Key Ingredients for Your Boursin Spaghetti Squash

Crafting this flavorful dish requires a handful of fresh, high-quality ingredients that work in harmony to create a truly memorable meal. Here’s what you’ll need, along with some tips for selection:

• Spaghetti Squash: This unique winter squash, sometimes affectionately called “vegetable spaghetti,” is the foundation of our dish. When cooked, its golden flesh magically separates into tender, noodle-like strands, offering a superb gluten-free and lower-carb alternative to traditional pasta. When choosing your squash, look for one that feels heavy for its size, has smooth, blemish-free skin, and a deep yellow or orange color. Avoid any with soft spots or dull skin. A medium-sized squash (around 2-3 pounds) is perfect for this recipe, yielding two generous halves.
• Boursin Cheese: The star ingredient that brings creamy indulgence and a burst of flavor! Also known as Gournay cheese, Boursin is a soft, spreadable cheese renowned for its rich taste and smooth texture. While “Garlic and Fine Herbs” is the classic and highly recommended flavor for this recipe, feel free to experiment with other savory varieties like “Chive & Onion” or “Black Pepper” if you prefer. This cheese melts beautifully, creating a luxurious sauce that coats every strand of spaghetti squash.
• Cherry Tomatoes: These small, sweet gems are ideal for roasting. Their thin skins allow them to burst easily in the oven, releasing their sweet, slightly acidic juices, which then meld with the Boursin to form a delectable sauce. Minimal seeds mean less fuss, and their quick cooking time makes them a perfect companion for the squash. You can also use grape tomatoes if cherry tomatoes aren’t available.

Pantry Staples & Fresh Enhancements:

Beyond the main stars, these everyday ingredients are crucial for rounding out the flavors and ensuring a perfectly balanced dish:

• Olive Oil: A good quality extra virgin olive oil is essential for roasting the squash to perfection and coating the vegetables for a rich, golden finish. It adds a subtle fruity note and helps carry the flavors.
• Garlic: Freshly minced garlic is non-negotiable! It provides a pungent, aromatic depth that complements the Boursin and tomatoes beautifully.
• Shallot (or Onion): Finely minced shallots offer a milder, more delicate onion flavor than a traditional onion, adding another layer of aromatic complexity. If you don’t have shallots, a small amount of finely minced yellow or red onion will work as a substitute.
• Fresh Basil: The vibrant, peppery sweetness of fresh basil is the perfect counterpoint to the rich cheese and roasted tomatoes. It’s added at the end to preserve its delicate flavor and bright color, truly elevating the Mediterranean profile of the dish.
• Salt and Pepper: Simple but critical seasonings. Use good quality sea salt and freshly ground black pepper to enhance and balance all the wonderful flavors. Remember to season generously!

Simple Steps to Craft Your Perfect Boursin Spaghetti Squash

This easy-to-follow recipe for spaghetti squash with Boursin cheese delivers a simple yet sophisticated dinner idea. It can also serve as a rich, creamy, and filling side dish that is effortlessly packed with nourishing veggies and fiber. Get ready for a delightful cooking experience!

1. Prepare and Roast the Spaghetti Squash: Begin by preheating your oven to 400ºF (204ºC). While it heats, carefully split your spaghetti squash in half lengthwise. Using a sturdy spoon, scoop out all the seeds and stringy bits from the center. Lightly brush the cut surfaces of each squash half with 1 tablespoon of olive oil, then season generously with salt and freshly ground black pepper. Place the squash halves cut-side down on a baking sheet (parchment paper is recommended for easy cleanup). Roast in the preheated oven for approximately 30 minutes, or until the flesh is tender enough to be easily pierced with a fork.
2. Craft the Flavorful Filling: While the squash is roasting, it’s time to prepare the vibrant filling. In a large mixing bowl, combine the remaining 3 tablespoons of olive oil, fresh cherry tomatoes, minced garlic, finely chopped shallots (or onion), and a pinch of salt and pepper. Toss all the ingredients thoroughly until the tomatoes and aromatics are well coated in the olive oil. This ensures an even roast and maximum flavor development.
3. Stuff and Encase with Boursin: Once the spaghetti squash is roasted and slightly cooled (handle with oven mitts or tongs!), carefully turn the halves over so their cavities are facing upwards. Evenly divide the prepared cherry tomato mixture between the two squash cavities. Don’t worry if some tomatoes overflow onto the baking sheet – they’ll still roast beautifully. Next, take your package of Boursin cheese, slice it in half (if it’s a block or round), and nestle one half into the center of the tomato mixture in each squash cavity. The cheese will melt down, creating an incredibly creamy sauce.
4. Final Roast for Bursting Flavors: Return the stuffed spaghetti squash halves to the oven. Increase the oven temperature to 425ºF (218ºC). Bake for another 20-25 minutes. During this stage, the cherry tomatoes will soften and begin to burst, releasing their sweet juices, while the Boursin cheese will melt into a luscious, golden, and slightly bubbly sauce. You might even see some slight browning on the cheese, indicating peak deliciousness.
5. Combine and Create the Sauce: Once the final roast is complete, carefully remove the baking sheet from the oven. Using a spoon, scoop out the roasted tomato filling and the melted Boursin cheese from the squash cavities and transfer them into a large bowl. Add the fresh basil to this mixture. Stir everything together, gently breaking down some of the softened cherry tomatoes with the back of your spoon. This action helps to create a wonderfully creamy and integrated sauce that perfectly infuses all the flavors.
6. Shred the Spaghetti Squash: Now for the signature spaghetti squash texture! Take a fork and gently scrape along the inside of each cooked squash half. The tender flesh will easily pull away in long, spaghetti-like strands. Leave these shreds directly in their cooked shells; they’ll be ready to be coated with our amazing sauce.

Serving Your Perfectly Prepared Boursin Spaghetti Squash

With your spaghetti squash shredded and your creamy Boursin-tomato sauce ready, it’s time for the grand finale – bringing all those incredible flavors together for a truly satisfying meal.

7. Assemble the Stuffed Squash: Take your luscious tomato and Boursin sauce and generously spoon it over the shredded spaghetti squash strands still nestled within their roasted shells. Gently toss with a fork directly in the shell to ensure every ‘noodle’ is coated with the rich, creamy sauce. This creates a beautiful, rustic presentation that’s as appealing to the eye as it is to the palate.
8. Garnish and Serve Immediately: For an extra touch of freshness and visual appeal, consider garnishing your Boursin Spaghetti Squash with a sprinkle of additional fresh basil leaves. A delicate drizzle of high-quality extra virgin olive oil can enhance the flavors, or a swirl of balsamic glaze can add a wonderful sweet and tangy contrast. This dish is best enjoyed immediately while warm, allowing the melted cheese and vibrant flavors to truly shine. Each stuffed spaghetti squash half typically makes about two servings when served as a hearty side dish, or it can be a perfectly satisfying single main course.

This dish is incredibly versatile for meal planning. While it stands proudly as a delicious vegetarian main course, it also pairs beautifully with a variety of proteins. Consider serving it alongside perfectly grilled chicken breast, flaky baked salmon, a tender steak, or even some pan-seared tofu for an extra boost of protein, transforming it into a complete and balanced meal.

Storing & Reheating Your Boursin Spaghetti Squash Leftovers

One of the best things about this Boursin Spaghetti Squash recipe is how well it holds up as leftovers, making it perfect for meal prep throughout the week. You can easily enjoy its delicious flavors for a few days after preparation.

To store, simply transfer any remaining portions to an airtight container. It will keep beautifully in the refrigerator for up to 3 days. We recommend reheating individual portions as needed to maintain the best texture and flavor. The microwave works wonderfully for a quick warm-up, ensuring the cheese melts back into a creamy consistency and the tomatoes warm through.

Top tip for storage: You have a couple of options for storing. You can either leave the shredded spaghetti squash and creamy sauce right inside their roasted shells for a convenient grab-and-reheat meal, or, if you prefer to save space, scoop out the combined squash flesh and sauce into a single airtight container. Both methods work great, just choose what’s easiest for you!

Please note that while the flavors remain excellent, the spaghetti squash might release a little more moisture upon reheating. A quick stir will re-incorporate everything into a creamy sauce. Avoid freezing this dish, as squash and creamy cheeses tend to change texture significantly when thawed, becoming watery or grainy.

Exciting Flavor Variations & Additions

While the classic Boursin Spaghetti Squash is undeniably delicious, this recipe is wonderfully adaptable to your tastes and what you have on hand. Feel free to get creative with these exciting variations:

• Tangy Goat Cheese: For a delightful twist, swap out the Boursin cheese for an equal amount of fresh goat cheese, often known as chèvre. Goat cheese offers a distinct tangy flavor and a slightly firmer, yet still creamy, texture that beautifully complements the sweetness of the roasted tomatoes and squash. It’s a fantastic option if you love a sharper cheese profile.
• Salty Feta Cheese: If you’re a fan of Mediterranean flavors, consider using feta cheese. Slice a 6-ounce block of firm feta cheese into two rectangular pieces and nestle them into the squash cavities in place of the Boursin. As it bakes, the feta will soften and become incredibly rich and salty, providing a wonderful contrast to the other ingredients.
• Cream Cheese for Mild Creaminess: For a milder, slightly sweeter creamy base, you can use brick-style cream cheese. Slice about 6 ounces of cream cheese into two squares and place them in the squash halves. It will melt into a smooth, comforting sauce, perfect if you prefer less assertive flavors. Consider adding a pinch of dried Italian herbs with cream cheese for extra depth.
• Boost with Chicken: To transform this vegetarian delight into a more substantial meal, add protein-packed chicken. Cut ½ to 1 pound of boneless, skinless chicken breasts into ½-inch cubes. Season them well with salt, pepper, and your favorite herbs (like oregano or thyme). For optimal and even cooking, it’s best to add these chicken cubes after the initial spaghetti squash roast. Instead of stuffing them tightly into the shell, spread them out evenly on the baking sheet alongside the stuffed squash halves during the second roasting phase. Ensure the chicken reaches an internal temperature of 165ºF (74ºC) before serving.
• Other Added Proteins: Beyond chicken, this dish welcomes a variety of cooked protein options. Consider flaked salmon, thinly sliced cooked steak, crumbled lean ground turkey, or even seasoned baked tofu cubes. Adding cooked chicken sausage or chickpeas can also provide a fantastic textural and protein boost. Incorporate these into the tomato and Boursin sauce before spooning it back into the squash shells for a truly satisfying main course.
• Spice It Up: For those who love a bit of heat, sprinkle in some red pepper flakes with your cherry tomatoes and garlic. A dash of smoked paprika can also add a delightful smoky depth.
• Sun-Dried Tomatoes: For an intensified tomato flavor, finely chop a few oil-packed sun-dried tomatoes and add them to your filling mixture.
• Spinach or Kale: Wilt a handful of fresh spinach or finely chopped kale into the hot tomato and Boursin sauce before combining with the squash strands for an extra dose of greens.

Helpful Substitutions to Fit Your Needs

This Boursin Spaghetti Squash recipe is designed to be flexible! Here are some smart substitutions to accommodate various dietary preferences or what you might have readily available:

• For Dairy-Free or Vegan Diets: Great news for those avoiding dairy! Boursin now offers a fantastic dairy-free and plant-based garlic and herb spread that works beautifully in this recipe. Simply substitute the traditional Boursin cheese with an equal amount of their vegan alternative to enjoy all the creamy, herb-infused flavor without any dairy.
• Gluten-Free Assurance: You’ll be happy to know that this recipe is naturally gluten-free as written, thanks to the spaghetti squash acting as a delightful pasta substitute. No modifications needed here – just pure, delicious, gluten-free goodness!
• Basil Alternatives: While fresh basil undoubtedly provides the most vibrant and aromatic flavor, we understand that sometimes fresh herbs aren’t readily available. In a pinch, you can absolutely use dried basil. As a general rule, use about one-third the amount of dried herbs compared to fresh (so, approximately 1 teaspoon of dried basil for every tablespoon of fresh). Dried oregano or a Mediterranean herb blend can also offer a lovely flavor profile if basil isn’t an option.
• Tomato Varieties: If cherry tomatoes aren’t available, grape tomatoes are an excellent direct substitute. You could also use larger tomatoes, diced, but be aware they may release more water during roasting and might require a slightly longer cooking time to soften.
• Shallot vs. Onion: As mentioned in the ingredients section, if you don’t have a shallot, about 2 tablespoons of finely minced yellow or white onion will work perfectly, though the flavor will be a bit more pronounced.
• Oil Choices: While olive oil is recommended for its flavor and health benefits, you can use other high-heat cooking oils like avocado oil if preferred.
• Garlic: If fresh garlic isn’t an option, a small amount of garlic powder (about 1/2 teaspoon per clove) can be used, though fresh is always best for maximum flavor.
