FAQs About Low Sodium Marinara Sauce

Yes, stewed tomatoes are excellent for marinara sauce as they break down easily and provide a rich, slightly sweet base flavor when blended.

Standard canned stewed tomatoes can be high in sodium, which is why this recipe specifically calls for "no-salt-added" stewed tomatoes to keep it heart-healthy.

The best way to reduce sodium is to make your own sauce using no-salt-added canned tomatoes and paste, relying on fresh or dried herbs like garlic, oregano, and parsley for flavor instead of salt.

How to Make Homemade Marinara Sauce with Fresh Tomatoes

If you have an abundance of summer produce, making a homemade marinara sauce with fresh tomatoes is a delicious, vibrant alternative to using canned stewed tomatoes. This simple swap delivers an authentic, bright Italian flavor while keeping your pasta sauce naturally low in sodium and perfectly heart-healthy.

  • Fresh Tomato Equivalent: To replace the 2 cans of no-salt-added stewed tomatoes, use approximately 2 to 2.5 pounds of fresh tomatoes (Roma or plum work best).
  • Instructions: Score the bottoms of the tomatoes with a shallow "X" and blanch in boiling water for 60 seconds. Transfer to an ice bath, peel the skins, and core them. Roughly chop the tomatoes, add to the food processor with the paste and seasonings, and blend. Simmer the sauce for an additional 10 to 15 minutes to allow the extra moisture to cook off.

Ingredient Spotlights: No-Salt-Added Canned Stewed Tomatoes and Tomato Paste

Using no-salt-added canned tomato products is the key to keeping this sauce heart-healthy. Stewed tomatoes are cooked down before canning, which concentrates their flavor and makes them perfect for a quick marinara. The tomato paste adds depth and thickness without the need for long hours of simmering.

Pro Tips

  • Blend to Your Preference: If you prefer a chunkier sauce, pulse the stewed tomatoes just a few times instead of blending until smooth.
  • Sautéing the Spices: For extra flavor, stir the dried oregano and garlic powder into the oil and onions for the last 30 seconds of sautéing to bloom the spices.

Healthy Variations

  • Spicy Marinara: Add ½ to 1 teaspoon of crushed red pepper flakes when sautéing the onions to make a spicy marinara sauce.
  • Creamy Marinara: Stir in 2 to 3 tablespoons of plain nonfat Greek yogurt, fat-free milk, or reduced fat coconut milk just before serving to create a rich, heart-healthy pink sauce without adding extra sodium.
  • Veggie-Packed Sauce: Sauté finely diced carrots, celery, or zucchini along with the onions before adding the tomato puree.
  • Herb-Loaded: Stir in a handful of fresh chopped basil just before removing the sauce from the heat for a bright, fresh finish.
