Are there low sodium marinara sauce brands?

I get it. You don’t always want to make everything from scratch. Sometimes you just want to buy a jar of sauce that won’t spike your blood pressure, right?

In general, look for a pasta sauce that’s less than 150mg sodium per serving. That still may be higher than you want, but you won’t break the sodium bank with that amount. You also want to check out the added sugar amount. Ideally, there would be none (and my recipe doesn’t have any!), but look for one that’s as low as you can find. There’s usually sugar added to jarred marinara sauce, but not always. Here are some brands to consider:

Tips and Substitutions

My sauce is too watery. How can I fix it?

Depending on how much water is in your tomatoes, this may happen – or it might just be thinner than you prefer! Either way, the good new is this is an easy fix. Return the sauce to the pan, bring to a simmer, and allow it to simmer with the lid off until enough liquid has evaporated to make it the consistency you prefer.

Can I use fresh herbs instead of dried?

If you prefer using fresh herbs, you will want to wait to put them in right before you blend your sauce. Use 4 Tbsp fresh basil, and 2 Tbsp fresh oregano.

Do you need recipes for your low sodium spaghetti sauce? I recommend serving this marinara sauce with Vegetarian Stuffed Peppers, Italian Style Black Bean Meatballs, or simply over your favorite whole grain pasta.

  • 2 tsp Olive Oil
  • 4 Garlic Cloves, minced
  • 5 lbs Fresh Tomatoes, chopped (56 oz canned Crushed Tomatoes, No Added Salt)
  • 1 Tbsp + 1 tsp Dried Basil
  • 2 tsp Dried Oregano
  • Pinch of Salt


  1. Heat the oil in a large skillet over medium heat, and add the minced garlic.
  2. Saute about a minute, until very fragrant, and add the tomatoes, basil, oregano, and salt.
  3. Bring to a simmer, reduce the heat to low, cover, and continue simmering for 15 minutes.
  4. Turn off the heat, uncover, and allow the sauce to cool a bit to avoid burns.
  5. Carefully, transfer the sauce to your food processor or blender. Process until the sauce is the level of smoothness you prefer. Be sure to vent the food processor or blender to allow the steam to escape.
  6. Return the sauce to the pan to warm through, if needed. Use as desired.

    The nutrition information following the recipe says it has 899.5mg of sodium per serving. I’m guessing that’s not the correct info for the recipe since it’s supposed to be a low sodium sauce. Any idea what the real nutrition information is for this recipe?

      Hi Heidi – Yikes! Thank you so much for mentioning that! That’s definitely not right, and I’m going to fix that ASAP! The amount per serving of sodium should be around 19 mg, give or take, depending on how big your “pinch” of salt is.
