Creamy Boursin Spaghetti Squash

I discovered this recipe during a particularly hectic autumn when I was determined to eat comfort food without the heavy carb aftermath. The first time I baked spaghetti squash, I stood in my kitchen genuinely amazed at how those golden strands appeared from what looked like an ordinary vegetable. My husband, initially skeptical of vegetable pasta, went back for seconds and actually asked when we could have it again. Now it has become our go-to dinner when we want something creamy and satisfying without that overstuffed feeling.

Last winter, my friend Sarah came over for dinner looking exhausted after a brutal week at work. I made this for her, watching her shoulders drop as she took that first creamy, herbaceous bite. She sat there quietly eating for several minutes before looking up and admitting this was exactly what her soul needed. Since then, she requests it every time she visits, and I have learned to always keep an extra Boursin wheel in my fridge.

Ingredients

• 1 large spaghetti squash: Pick one that feels heavy for its size with a hard, unblemished skin
• 2 cups baby spinach leaves: Fresh spinach wilts beautifully and adds lovely color against the golden squash
• 1 small shallot: Shallots give a milder, sweeter flavor than onions which works perfectly here
• 2 cloves garlic: Freshly minced garlic makes all the difference in the aromatic base
• 1 package Boursin Garlic & Fine Herbs cheese: This creamy cheese is the secret weapon that makes everything luxurious
• 2 tbsp grated Parmesan cheese: Adds a salty, nutty finish that brightens the rich dish
• 2 tbsp olive oil: Use good quality olive oil for roasting and sautéing
• 1/4 tsp freshly ground black pepper: Freshly cracked pepper has more complex flavor
• 1/4 tsp kosher salt: Kosher salt adheres better to the squash during roasting
• Pinch of red pepper flakes: Just enough to give a gentle warmth without overwhelming

Instructions

Preheat and Prepare:

Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup

Prep the Squash:

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

Roast Until Tender:

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

Sauté Aromatics:

Heat remaining olive oil in a large skillet over medium heat, add shallot and garlic, and cook for 2 to 3 minutes until fragrant

Wilt the Spinach:

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

Create the Strands:

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

Bring It All Together:

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

Season to Perfection:

Taste and adjust with additional salt, pepper, or red pepper flakes if needed

Finish and Serve:

Transfer to a serving dish and sprinkle with grated Parmesan cheese while still warm

One rainy Sunday, I made a double batch and brought some to my elderly neighbor who had been feeling under the weather. She called me the next day to say it was the first thing in days that had truly tempted her appetite. There is something profoundly nourishing about food that is both healthy and indulgent.

Make It Your Own

I have found that sautéed mushrooms add a wonderful earthy depth that pairs beautifully with the herbaceous Boursin. Roasted cherry tomatoes bring bursts of sweetness that cut through the richness. Sometimes I add a handful of chopped walnuts for crunch.

Perfect Pairings

A crisp white wine like Sauvignon Blanc or Pinot Grigio complements the creamy sauce perfectly. I often serve this with a simple arugula salad dressed in lemon vinaigrette. The bright, peppery greens balance the rich, warm squash beautifully.

Storage and Meal Prep

This keeps well in the refrigerator for up to four days and actually benefits from sitting overnight. Store in an airtight container and reheat gently with a splash of water. The texture remains surprisingly good for leftovers.

• Freeze individual portions for up to three months if you want to meal prep
• Thaw overnight in the refrigerator before reheating for best results
• Add a fresh sprinkle of Parmesan when reheating to revive the flavors

This recipe has taught me that healthy comfort food is not an oxymoron. Sometimes the simplest vegetables, treated with a little love and the right cheese, become something extraordinary.

Recipe FAQ

→ Can I make this ahead of time?

Absolutely. Roast the squash and prepare the spinach mixture up to 2 days in advance. Store them separately in the refrigerator, then combine and reheat gently in a skillet until warmed through and the cheese melts.

→ What can I use instead of Boursin cheese?

Cream cheese blended with fresh herbs, garlic, and a touch of Parmesan makes a lovely substitute. Alternatively, goat cheese crumbles work well for a tangier profile, or try Alouette cheese for similar creaminess and herbs.

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

The squash is ready when the flesh yields easily to a fork and shreds into strands naturally. This typically takes 35-40 minutes at 400°F. The skin should feel tender when pressed, and you should be able to scrape the entire interior into spaghetti-like strands.

→ Is this dish keto-friendly?

Yes, this dish works beautifully for ketogenic diets. Spaghetti squash contains about 7 grams net carbs per cup, and Boursin cheese adds minimal carbohydrates. The entire dish comes to roughly 8 grams net carbs per serving, fitting well within most keto guidelines.

→ Can I freeze leftovers?

While possible, freezing may affect the texture slightly. The squash can become somewhat watery upon reheating. If freezing, portion into airtight containers and thaw overnight in the refrigerator before reheating in a skillet over medium heat to evaporate excess moisture.

→ What protein would pair well with this?

Grilled chicken, pan-seared salmon, or roasted shrimp complement the creamy flavors beautifully. For a vegetarian option, serve alongside chickpeas or add toasted walnuts for crunch. The dish also stands alone as a satisfying main with its cheese and vegetable content.
