I've been making this sauce for years because it's so easy and adds an amazing flavor to any dishes, not just pasta! I like to serve mine with meatballs and vegetable pasta alternatives like zucchini noodles.

Just like this Baked Feta Pasta Sauce, it's so versatile, plus it's also dairy-free! If you're planning to use it as pasta sauce, simply heat up and serve with your favorite low-carb pasta options such as zucchini noodles, palmini noodles, or shirataki noodles.

This sauce can also be used as a base for casseroles, meatballs and you can even use it to make bolognese-style dishes or keto lasagna. It works well on pizza because you can use it just like you would Marinara Sauce, or simply bake with some chicken.

Finally, this sugar-free tomato sauce is great for meal prep and batch cooking. It's easy to portion it up and freeze it so you've got a tasty sauce ready for future meals.

Ingredients (makes about 4 cups, 960 ml)

  • 450 g canned peeled tomatoes (1 lb)
  • 4 large celery stalks, sliced (300 g/ 10.6 oz)
  • 1 large brown onion, diced (150 g/ 5.3 oz)
  • 4 cloves garlic, sliced
  • 1/4 cup extra virgin olive oil (60 ml/ 2 fl oz)
  • 1 tsp sea salt
  • 1/2 tsp black pepper
  • Optional: 1 tbsp Worcestershire sauce


  1. Dice the onion. Slice the celery stalks and garlic. Pour the olive oil in a saucepan and add onion. Fry for 3 to 5 minutes, until lightly browned and fragrant. You can fry it longer for more caramelized flavor. Add garlic and cook for another 30 seconds. Tomato & Celery Pasta Sauce
  2. Finally add celery, tomatoes, salt and pepper. Optionally add 1 tablespoon of Worcestershire sauce. Cover with a lid and reduce the heat to low-medium. Simmer until the celery is tender, for 20 to 30 minutes. Tomato & Celery Pasta Sauce
  3. Remove the lid and give it a good stir. Set aside to cool down a little before using an immersion blender and processing until smooth. Tomato & Celery Pasta Sauce
  4. Let it cool down completely before pouring in saleable jars. Store in the fridge in sealed jars for up to a week. For longer storage, transfer to an ice tray or small freezer-friendly containers and freeze for up to 6 months. When ready to use, just pop out a few cubes.
  5. Serve with zucchini noodles, palmini noodles or shirataki noodles and protein options of choice (chicken or any meatballs work best). Tomato & Celery Pasta Sauce

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Do I have to purée? I prefer chunks of celery.
Also I only have diced tomatoes. Can I use a can of those instead?

Not at all! You could use something like potato masher if you prefer yours chunky 😊 Diced tomatoes are fine, they are soft anyway.
