How to Make Boursin Spaghetti Squash
Step 1: Roast the Squash
Preheat the oven to 400°F. Halve the squash lengthwise, scoop the seeds, drizzle with olive oil, and season. Pierce the skin 5 to 6 times and roast cut side down for 35 to 40 minutes until tender.
Step 2: Bake the Tomatoes
In a small baking dish, combine the cherry tomatoes, olive oil, garlic, and seasonings. Place the Boursin in the center and bake for 20 minutes until the tomatoes burst.
Step 3: Toss
Scrape the squash into strands. Top with the tomato Boursin mixture and Parmesan and toss until creamy.
Step 4: Finish
Top with basil and your protein of choice.
Carly’s Expert Tips
- Pierce the skin. It helps the squash cook evenly and prevents bursting.
- Roast cut side down. This steams the inside for tender strands.
- Don’t overcook the squash. Mushy squash won’t form strands.
- Stir well. Smash the tomatoes into the cheese for the creamiest sauce.
Make It Your Own
- Add protein: Chicken, shrimp, or Italian sausage.
- Pasta version: Use the sauce on regular pasta.
- Greens: Stir in baby spinach until wilted.
- Balsamic: Finish with a drizzle of balsamic glaze.
Make-Ahead and Meal Prep: Roast the squash up to 3 days ahead and refrigerate. Bake the tomato Boursin sauce and toss right before serving.
What to Serve With Boursin Spaghetti Squash
Pair it with grilled chicken, garlic bread, a green salad, or roasted broccoli for a full, cozy meal.
Storing and Reheating
Fridge: Store leftovers in an airtight container for up to 3 days.
Reheat: Warm in a skillet or microwave until heated through.
Freezer: Not recommended, since the squash gets watery.
