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 circulating 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.

- Roast the spaghetti squash for 45 minutes, or until the shreds easily pull away from the skin and are tender.
- Place the block of feta cheese in a the center of a large baking dish. Add the tomatoes to the dish and place them all around the feta.

- Drizzle the olive oil and balsamic over top of the feta, tomatoes and garlic.
- 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.
- Add the 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.

- 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 you pasta.

Adding the balsamic was genius! My teenager said this “slapped!” (That’s good, right? ) I also added some capers. Stirred together it wasn’t the prettiest dish but it was yummers!

Susan says
We had this for dinner tonight and it was so good! I had a lot of liquid on my pan from the tomatoes so I spooned it out into a measuring cup. I used a hand blender to mix in a teaspoon of xanthum gum with the liquid then poured back into the tomato mixture. It came out so creamy and delicious. Great idea to add balsamic!
