Ingredients Needed

Chopped onions - When it comes to choosing the best onion for marinara sauce, many chefs and home cooks prefer using yellow onions. This is because yellow onions have a strong flavor that can hold up well against the acidity of the tomato sauce.
No salt added tomato sauce - Tomato sauce can be found in many varieties, including chunky, smooth, spicy, and sweet. If the tomatoes are chunky just puree them in a food processor. If you can only find no salt added tomatoes just puree them in your blender.
No salt added tomato paste - Is a thick and concentrated sauce made by cooking and straining tomatoes.
Sugar - Use granulated white sugar
Garlic, diced or minced - Chopped fresh garlic can take some time to chop so I often always use the freshly minced garlic that comes already made in a jar.
Ground oregano - Is an herb that is commonly used in Mediterranean cooking and it belongs to the mint family. Oregano has a strong, slightly bitter taste and a pungent aroma.
Dried basil is made by drying the leaves of the basil plant and can be found in most grocery stores.
Crushed red pepper flakes - Are small pieces of dried hot peppers, typically made from cayenne, that are crushed or ground into small flakes.
Water - This ingredient is free, you can find it in the sink in your kitchen. 😉

How to Make Low Sodium Marinara Sauce

Step 1: Spray a non-stick pan with cooking spray. Set to medium-low heat. Cook the onions until they're translucent.

Step 2: Add the tomato sauce and tomato paste; then water. Stir in all the spices, and let the sauce simmer on low for 30 minutes.

Recipe Tip: If you don't like chunky onions use a hand-held immersion blender to puree the sauce. A blender will also work.

Step 3 While your sauce is simmering, check your pasta box! Most dry pastas are naturally sodium-free but if you’re using fresh store-bought pasta or certain egg noodles, they can sneak in up to $50 per serving.

Flavor Hacks for Low-Sodium Sauce

The Power of Acid: If your sauce tastes "flat," add a splash of balsamic or red wine vinegar, or even a squeeze of fresh lemon juice at the end. Acid tricks the palate into thinking there is more flavor than there is.
Aromatics are Key: Don't skimp on the base. Sautéing plenty of garlic, onions, and even celery or carrots (soffritto) in olive oil builds a deep, savory foundation that compensates for the lack of salt. Add in some fresh
Herbs and Spices: Lean into fresh herbs like basil, oregano, and parsley. Dried spices like red pepper flakes, smoked paprika, or a little bit of cinnamon can add complexity and warmth. Weight Wathchers Pesto
Umami Boosters: Since you aren't using salt, use ingredients that provide natural glutamates. A tablespoon of tomato paste, some roasted mushrooms, or even a splash of coconut aminos (which has less sodium than soy sauce) can add that "meaty" depth.
Use High-Quality Tomatoes: Start with "no salt added" crushed or whole peeled canned tomatoes.

Shopping for Low-Sodium Sauce: What to Look For

When you’re in a pinch, not all "heart-healthy" labels are created equal. Here is how to spot the winners:

Check the "No Salt Added" Label: This is the gold standard. These sauces usually contain only the sodium naturally found in tomatoes (around 35mg–50mg per serving).
The 5% Rule: A quick pro-tip for your readers—look at the Daily Value (DV) percentage. If a serving has 5% DV of sodium or less, it’s considered low-sodium. If it has 20% or more, put it back!
Watch for "Hidden" Sodium: Even if the front says "organic" or "natural," check the back for ingredients like celery salt or parmesan cheese, which drive up the count.

What to serve with spaghetti sauce?

Make my Air Fryer Garlic Bread to serve on the side or Easy Cheesy Garlic Bread Sticks.

Sometimes I'll make a bag of Ceasar salad from the store as a side dish.

Marinara sauce and spaghetti noodles can be a quick meal to make at home. Add in some ground beef for some protein. I like to buy the 96% lean ground beef at Aldi to add to this pasta sauce. One 2oz serving of this sauce with the ground beef added is 2 smart points.

If you're vegetarian add in some soy crumbles. Banza pasta has a pretty decent source of protein in just the noodles.
