Preheat and Prepare: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Prep the Spaghetti Squash: Halve the squash lengthwise and scoop out the seeds. Brush the flesh of each half with 2 tablespoons of olive oil (1 tbsp per half). Season generously with sea salt and freshly ground pepper. Place the squash halves cut-side up on the prepared baking sheet.
Assemble the Filling: In a medium bowl, combine the cherry tomatoes, minced garlic, chili flakes, oregano, and 1 tablespoon of olive oil. Place half of the feta block into the hollow of each squash half, then spoon the tomato mixture evenly over the feta. Drizzle with a little more olive oil.
Bake to Perfection: Bake for 55–65 minutes, or until the squash is fork-tender and the tomatoes are bursting. The exact timing may vary depending on the size of your squash.
Serve and Garnish: Using a fork, gently scrape the squash flesh to separate it into strands and mix everything together in the squash halves. Garnish with fresh basil leaves and serve warm. Enjoy!
