Boursin Spaghetti Squash

The first time I served this at a dinner party, my carb loving friend went back for thirds before realizing she had not eaten a single noodle. The way that Boursin cheese melts into the warm squash strands creates this impossibly creamy sauce that feels indulgent but is actually quite light.

I discovered this combination during a rainy October when I wanted something cozy but was trying to cut back on pasta. My kitchen smelled amazing as the squash roasted, and that first creamy bite convinced me low carb did not mean low flavor.

Ingredients

• Large spaghetti squash: Look for one that feels heavy for its size with a hard, dull rind
• Baby spinach leaves: Fresh wilts beautifully and adds a pop of color against the pale squash
• Shallot: More subtle than onion and mellows perfectly as it sautes
• Garlic cloves: Minced fresh releases more oils and flavor than pre minced
• Boursin Garlic and Fine Herbs cheese: This French cheese is the secret weapon that brings everything together
• Grated Parmesan cheese: Adds a salty, nutty finish on top
• Olive oil: Helps the squash roast evenly and carries the seasonings
• Freshly ground black pepper and kosher salt: Simple seasonings that let the Boursin shine
• Red pepper flakes: Optional but lovely if you like a gentle heat background

Instructions

Get the oven going:

Preheat to 400°F and line a baking sheet with parchment paper for easy cleanup

Prep the squash:

Carefully cut the squash in half lengthwise, scoop out seeds, then drizzle with half the olive oil and season with salt and pepper

Roast until tender:

Place squash cut side down on the baking sheet and roast for 35 to 40 minutes until a fork easily pierces the flesh

Build the flavor base:

While squash roasts, heat remaining oil in a skillet and saute shallot and garlic for 2 to 3 minutes until fragrant

Wilt the spinach:

Add spinach to the skillet and stir for about 2 minutes until just wilted, then remove from heat

Create the strands:

When squash is cool enough to handle, use a fork to scrape the flesh into strands that look just like spaghetti

Bring it all together:

Add squash strands to the skillet with spinach, crumble in the Boursin, and toss until melted and creamy

Finish and serve:

Taste and adjust seasonings if needed, then transfer to a serving dish and sprinkle with Parmesan

My sister texted me at 11pm the first time she made this, saying she could not believe a vegetable dinner could feel this satisfying. Now it is her go to when she wants something that feels special without hours in the kitchen.

Making It Your Own

Sauteed mushrooms add an earthy depth while roasted cherry tomatoes bring bursts of sweetness. Both cook beautifully alongside the shallots and need only a few extra minutes.

Green Swaps

Kale holds up nicely if you want something more hearty, while arugula wilts quickly and adds a peppery kick. Both work with the creamy base just as well as spinach.

Serving Suggestions

A crisp green salad with lemon vinaigrette cuts through the richness. A chilled white wine like Sauvignon Blanc pairs perfectly.

• Grilled chicken or shrimp can turn this into a more substantial main
• Crusty bread on the side is never a mistake, even if the squash itself is enough
• Leftovers reheat beautifully with a splash of water to loosen the sauce

This is the kind of recipe that reminds you why simple ingredients treated with care can taste absolutely extraordinary.

Recipe FAQs

→ What does Boursin spaghetti squash taste like?

The natural sweetness of roasted spaghetti squash pairs beautifully with Boursin's creamy, herbaceous profile. The garlic and fine herbs in the cheese complement the squash's mild flavor, while spinach adds earthiness and Parmesan provides a savory finish.

→ Can I make this dish ahead of time?

You can roast the spaghetti squash up to 2 days in advance and store the strands in the refrigerator. Reheat gently in a skillet before tossing with the Boursin and spinach for best results. The final assembly comes together quickly when prepping ahead.

→ Is this suitable for low-carb or keto diets?

Absolutely. With only 16 grams of carbohydrates per serving, this makes an excellent low-carb option. The Boursin and Parmesan provide satisfying fats and protein, while the spaghetti squash offers fiber and texture without the carb load of traditional pasta.

→ What can I substitute for Boursin cheese?

Soft goat cheese blended with fresh herbs, garlic, and a touch of cream creates a similar texture and flavor profile. Alternatively, cream cheese mixed with minced garlic, parsley, chives, and thyme works well. For a dairy-free version, try a cashew-based herb spread.

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

The squash is ready when a fork easily pierces through to the skin and the flesh shreds into strands without resistance. This typically takes 35-40 minutes at 400°F. Let it cool briefly before handling, as the strands release more easily when warm but not scorching hot.

→ Can I add protein to this dish?

Grilled chicken, pan-seared shrimp, or crispy pancetta make excellent additions. For a vegetarian protein boost, consider white beans or chickpeas stirred in during the final tossing. Add proteins after combining the squash with the cheese mixture to maintain the creamy texture.
