Ingredients

Spaghetti Squash

  • 1 spaghetti squash, halved and seeds removed (about 2-3 pounds)
  • 4 tablespoons olive oil, divided
  • Salt and pepper to taste

Filling

  • 1 ½ cups cherry tomatoes
  • 3 cloves garlic, minced
  • 1 shallot, minced (or 2 tablespoons minced onion)
  • 1 package (150g) Boursin Gournay cheese (Garlic and fine herbs or preferred flavor)
  • ¼ cup fresh basil, chopped

Instructions

  1. Preheat and prepare squash: Preheat the oven to 400ºF (204ºC) and line a baking sheet with parchment paper. Brush 1 tablespoon of the olive oil over the cut sides of the spaghetti squash and season generously with salt and pepper.
  2. Roast squash: Place each half cut-side down on the baking sheet and roast for 30 minutes until tender and easily pierced with a fork.
  3. Prepare filling ingredients: Carefully turn the spaghetti squash halves over and set aside. In a bowl, combine cherry tomatoes, minced garlic, shallot, salt, pepper, and the remaining 3 tablespoons of olive oil, tossing well to coat.
  4. Fill squash halves: Divide the cherry tomato mixture evenly into the hollowed centers of the spaghetti squash halves, allowing some to spill if necessary.
  5. Add cheese: Cut the Boursin cheese in half and place each half inside the hollow of each squash half on top of the tomato mixture.
  6. Roast again: Increase the oven temperature to 425ºF and roast the stuffed squash for 20-25 minutes until the cherry tomatoes begin to burst and cheese is warmed through.
  7. Prepare spaghetti squash strands: Remove the squash from the oven and transfer the tomato and cheese filling to a bowl. Use a fork to shred the inside flesh of the squash halves, leaving the shreds inside the shells and set aside.
  8. Mix filling: Add the fresh basil to the tomato mixture, season with flaky salt and pepper, and stir gently, breaking up some tomatoes to combine flavors.
  9. Assemble and serve: Spoon the tomato and cheese mixture back into the squash shells evenly. Garnish with additional fresh basil, a drizzle of olive oil, or balsamic glaze if desired. Serve immediately.

Notes

  • Serve with chicken, salmon, steak, tofu, or your favorite high-protein main or side dishes for a balanced meal.
  • Store leftovers in the squash shells or remove filling and shreds into an airtight container. Refrigerate for up to 3 days and reheat in the microwave for best results.
  • For added protein, add ½” cubes of uncooked seasoned chicken breast when adding the filling; space evenly on the baking sheet since the squash cavity may be too small.
  • Substitutions:
    • Dairy-free or vegan option: Use dairy-free Boursin spread instead of classic Gournay cheese.
    • Gluten-free: This recipe is naturally gluten-free.
    • Protein additions: Add cooked chicken, salmon, steak, or chicken sausage as desired.
    • Cheese alternatives: Substitute Boursin with equal amounts of goat cheese, 6 ounces feta cheese (split into two rectangles), or 6 ounces cream cheese.
