These Thai Peanut Spaghetti Squash Boats have become a go-to in my kitchen for bringing bold flavors to the table while keeping things light and nourishing. With a silky peanut sauce and an abundance of colorful vegetables, this meal transforms humble squash into something truly special. I love making these boats when I want a filling, veggie-packed main dish with a taste of Southeast Asia, minus the takeout.

Whenever I make this for friends, the serving presentation always gets oohs and aahs. My family first tried these boats on a chilly weekend and it instantly became the dish we crave when we want something comforting but still good-for-you.

Ingredients

  • Spaghetti squash: Two medium Choose firm squash with unblemished golden skin They create the perfect edible bowl with tender noodle-like strands
  • Olive oil: Adds richness and helps caramelize the edges of the squash Opt for extra-virgin for more flavor
  • Salt and black pepper: Essential for seasoning the squash and enhancing all the flavors Use sea salt and freshly cracked pepper if possible
  • Red bell pepper: Thinly sliced for sweetness and vivid color Pick peppers that feel heavy for their size and have glossy skin
  • Shredded carrots: Add crunch and vibrant orange color Pre-shredded saves time but fresh has the best snap
  • Snap peas: Halved for crisp texture and a dose of green Choose bright green pods with no wilting
  • Green onions: Sliced for mild onion flavor and a pretty garnish Use both green and white parts for extra taste
  • Cilantro: Chopped fresh for herbal brightness Go for leaves with no yellowing or limpness
  • Roasted peanuts: Roughly chopped for salty, nutty crunch Buy roasted unsalted and chop just before serving for best texture
  • Creamy peanut butter: The backbone of the Thai-inspired sauce Use natural peanut butter with minimal added sugar
  • Soy sauce or tamari: Salty depth to balance the peanuts Choose tamari for gluten-free or low sodium options
  • Rice vinegar: Adds tang to the sauce Look for unseasoned for better control of flavors
  • Lime juice: Gives fresh zing Squeeze from a ripe lime for brightness
  • Honey or maple syrup: Sweetens and balances spice Use maple syrup for a vegan dish
  • Toasted sesame oil: A little goes a long way for nutty aroma Be sure it is toasted for true flavor
  • Sriracha or chili garlic sauce: For taming or ramping up the heat Adjust to your personal taste but taste the sauce as you go
  • Warm water: Used to thin out the peanut sauce until perfectly creamy Add just enough for a pourable consistency
