Baby and kid friendly pizza sauce

There’s a lot to love about this simple, homemade sugar free pizza sauce—especially when you’re cooking for kids or babies. Here are just a few reasons why it’s become a go-to in our kitchen:

  • Versatile – Works just as well on pizza as it does in pizza quesadillas, stirred into lentils, or even savory oatmeal.
  • No added sugar or salt – Naturally flavorful without relying on extra sodium or sweeteners.
  • Thick and hearty – Won’t run off the crust or make things soggy, perfect for little hands.
  • Made with pantry staples – No last-minute grocery runs needed.
  • Freezer-friendly – Make a batch and stash extras for quick meals down the road.
  • Nutrition-packed – Hemp seeds add healthy fats and a little plant-based protein boost.
  • Family-friendly flavor – Bold enough for grown-ups, mild enough for toddlers and babies.

Ingredients

all the ingredients laid out on a wooden board
  • Tomato paste – Adds rich, concentrated flavor and helps thicken the sauce, so don’t skip it. Add it early with the aromatics so it caramelizes and sweetens, boosting depth. Another awesome thing about tomato paste is that it’s actually a great source of iron! Pro tip – Once opened, freeze leftover tomato paste in 1-tablespoon portions for easy use next time.
  • Crushed tomatoes – Use a really good canned tomato like San Marzano. It is the main ingredient so don’t skimp on it! You’ll definitely taste the difference. These give the sauce body and texture without being too chunky.
  • Onion – Adds a natural sweetness and savory base without the need for added sugar. Be sure to finely grate or mince. I like to use my mini food chopper for small tasks like this (linked in the recipe card below).
  • Hemp seeds – They may be tiny but are packed with essential nutrients, including omega 3 fatty acids, iron, zinc, fiber, and protein (like quinoa, contain all the essential amino acids making them a complete protein source). Such an easy way to boost nutrition!
  • Fresh basil: Really brightens up the sauce! You can use dried if you wish. Just add it along with oregano.

Substitutions

If you’re missing an ingredient or need to make a quick swap, here are some easy substitutions to keep your sauce delicious and flexible:

  • Want extra veggies? Add grated carrot or finely chopped bell pepper when sautéing the onion.
  • No hemp seeds? Try ground flaxseed, chia seeds, or even a spoonful of this homemade sunflower seed butter for similar creaminess and nutrition.
  • No fresh basil? Use 1 teaspoon dried basil or substitute fresh parsley or a spoonful of pesto. Try one of these for a flavor twist: sun-dried tomato pesto, easy ricotta pesto, or easy zucchini pesto with almonds.
  • Low on tomato paste? Sub ¼ cup of tomato purée or cook the sauce a bit longer to thicken it naturally.
  • Avoiding onion? Try finely chopped shallots or a pinch of onion powder.

Recipe Tips

  • Simmer for flavor: The longer you let the sauce simmer, the more the flavors will develop. Aim for at least 15-20 minutes for the best depth of flavor.
  • Adjust thickness: If you prefer a thinner sauce, add a splash of water or vegetable broth while simmering. For a thicker consistency, let it cook a little longer.
  • Make ahead: This sauce can be made in advance and stored in the fridge for up to 5 days or frozen for up to 3 months. Just be sure to let it cool completely before storing.
  • Spice it up: For an extra kick, add a pinch of red pepper flakes or a dash of hot sauce while cooking the sauce.
  • Customize the herbs: Feel free to play with the herbs! A mix of oregano, thyme, and even a bit of rosemary can give the sauce a unique flavor profile.

Frequently Asked Questions

Can I use tomato sauce instead of crushed tomatoes?

You can but when I did a side by side taste test, crushed tomatoes tasted better! It also provides just the right texture – not too watery or chunky.

If you use whole tomatoes in a can, add to food processor/blender and blend to a crushed texture

Can I use this sugar free pizza sauce for pasta?

I don’t recommend it. It is way too thick and concentrated. You can thin it out with water or broth, if you really want to toss it with pasta. If you’re looking for a delicious spaghetti sauce, give this veggie-loaded baby pasta sauce a try!

How to reduce acidity of this sugar free pizza sauce?


Tomatoes are one of the most acidic fruits, and the acid content of canned tomatoes varies. That’s why I recommend using high-quality tomatoes. Paying the extra couple of dollars will be well worth it!

In addition, caramelizing onion & tomato paste and simmering, as you see in this recipe, will help the flavors to become more concentrated and balance the acidity.

If necessary, you can add a pinch of baking soda.
Keep in mind, this sauce will be spread onto pizza dough, tortilla, bread, etc. and enjoyed with all kinds of toppings, which will also help mellow out the slight bitterness.

Can I freeze this no sugar pizza sauce?

Yes! Cool completely in the fridge and portion into freezer-safe containers. Will keep for up to 3 months. When ready to enjoy, thaw in the fridge overnight.

Is this sugar free pizza sauce suitable for babies or toddlers?

Yes! This sauce contains no added sugar or salt, and it’s full of nourishing ingredients. For younger babies, you can blend it smooth if needed.

Can I double the recipe?

Yes, and I often do. It’s a great one to batch cook and freeze for easy meals later.
