Keto Baked Feta Pasta with Tomatoes

Keto Baked Feta Pasta with Tomatoes

This keto baked feta pasta with tomatoes is my low carb take on the viral TikTok sensation. Using spaghetti squash in place of pasta makes it a dish that low carbers and non-low carbers alike can enjoy.

After about the 100th time I saw this viral pasta recipe on TikTok, I just knew that I had to make a low carb baked feta pasta version. It’s just too good to not have to circulate around the low carb world also. But to give credit where credit is due, I had to do some digging to find the actual origin. From what I could trace back, the original version was created in 2019 by a Finnish food blogger named Jenni Häyrinen. TikTok got ahold of it in late 2020 and the rest is history.

Most of the versions I saw were simply tomato, feta, olive oil, salt, pepper, and pasta. But I had to kick things up a notch and add a whole lot of garlic, some balsamic vinegar, red pepper flakes, dried Italian seasoning, more feta, some Parmesan cheese, and cracked black pepper. In fact, it took some restraint to not keep adding more flavor. But I did want to keep it close to the original viral TikTok pasta, but with my own flair and a low carb and gluten-free spin, of course.

  • Author: Kyndra Holley
  • Prep Time: 15 minutes
  • Cook Time: 45 minutes
  • Total Time: 1 hour
  • Yield: 6 servings
  • Category: Pasta


  • 1 large spaghetti squash or 2 small, halved, and seeded
  • 8-ounce block feta cheese
  • 3 cups grape tomatoes (2 pints)
  • 1 small bulb garlic
  • ¼ cup olive oil
  • 2 tablespoons balsamic vinegar
  • 1 teaspoon sea salt, more to taste
  • ½ teaspoon black pepper
  • ½ teaspoon dried Italian seasoning
  • Pinch of red pepper flakes
  • 5 fresh basil leaves, torn
  • ½ cup shredded parmesan cheese, optional
  • cracked black pepper, optional


  1. Preheat the oven to 400°F. Line a rimmed baking sheet with parchment paper.
  2. Drizzle the spaghetti squash halves with a little olive oil, and sprinkle with salt and pepper.
  3. Roast the spaghetti squash for 45 minutes, or until the shreds easily pull away from the skin and are tender.
  4. Place the block of feta cheese in the center of a large baking dish. Add the tomatoes to the dish and place them all around the feta.
  5. Slice the top off of the bulb of garlic, exposing all of the cloves, and add it to the baking dish with the tomatoes and the feta.
  6. Drizzle the olive oil and balsamic over top of the feta, tomatoes, and garlic.
  7. Sprinkle over the salt, pepper, Italian seasoning, and red pepper flakes. Toss the tomatoes so that they are evenly coated in the oil, vinegar, and seasonings.
  8. Add the baking dish to the oven with the spaghetti squash and cook for 30 minutes, or until the tomatoes are just about to burst, the cheese is melty, with a golden brown top, and the garlic is roasted.
  9. Once they are done, squeeze the garlic cloves out of the bulb into the baking dish with the tomatoes.
  10. Using a fork, gently start popping the tomatoes, mashing the garlic, and mixing them into the cheese as you go. This will be the sauce for your pasta.
  11. Add the fresh torn basil and the roasted spaghetti squash and toss until the squash is evenly coated in the sauce.
  12. Top with Parmesan cheese and cracked black pepper before serving.
