Ingredients Needed:
- 1 medium spaghetti squash: baked until tender and fork-scrapable
- ½ cup cherry or grape tomatoes: halved, roasted (swap for sun-dried tomatoes)
- 1 cup fresh spinach: chopped
- ¼ cup fresh basil: loosely chopped
- 1 tablespoon butter: optional, for richness
- 1 tablespoon extra virgin olive oil: for flavor
- Salt and pepper: to taste
How To Make Low FODMAP Spaghetti Squash:
Roast the Squash:
Preheat your oven to 375°F (190°C). Poke the squash all over with a fork and roast whole for 45–60 minutes, or until a fork slides in easily.
Prep the Tomatoes:
While the squash is roasting, place the halved cherry tomatoes on a baking sheet. Roast them in the oven during the last 20 minutes of squash cooking time until soft and slightly browned.
Cool and Scrape:
Let the squash cool slightly. Cut it in half lengthwise, scoop out the seeds, then use a fork to scrape the strands into a large bowl.
Toss Everything Together:
Add butter, olive oil, roasted tomatoes, spinach, basil, salt, and pepper to the squash. Stir until everything is combined and the spinach wilts slightly from the heat.

Recipe Tips:
- Cherry tomatoes provide the sweet, rich flavor of sun-dried tomatoes without the FODMAPs.
- Add a squeeze of lemon juice for extra brightness.
- Use dairy-free butter if needed — many are Low FODMAP.
- You can bake the squash ahead and reheat when ready to serve.
How to Store & Reheat:
- Room Temperature: Not recommended — refrigerate within 2 hours.
- Fridge: Store in a sealed container for up to 4 days.
- Freezer: Freeze in portions up to 2 months. Reheat in microwave or skillet until hot.
