Baby and kid friendly pizza sauce

This tomato sauce is bursting with flavor without all the sugar, salt, and additives that are normally found in store-bought versions. It’s also rich and THICK as any good pizza sauce should be. It won’t run off the crust or make it soggy.

Having said this, we all need a break from cooking sometimes, and it’s so nice to have store-bought sauce on hand for days when we just…can’t. When choosing one to enjoy with your baby, the most ideal option is one with minimal ingredients, sodium and sugar.

Ingredients

all the ingredients laid out on a wooden board

Tomato paste: This is a very important ingredient so don’t skip it. It adds a rich, concentrated tomato flavor and really thickens up the sauce. When adding to this sauce as well as others, be sure to incorporate it at the beginning of the cooking process alongside other aromatics. As it caramelizes, it will taste less bitter and become sweeter, adding great depth and structure.

Another awesome thing about tomato paste is that it’s actually a great source of iron!

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.

Onion: 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 hearts: 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.

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 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?


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 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.

Are tomatoes an allergen? My baby gets a rash around the mouth after consumption

Tomatoes are not a common allergen. But they can cause a skin rash upon contact, which is oftentimes harmless. Same goes for other acidic foods. This happened to my firstborn with tomatoes and eggplant.

So how can you tell if your baby is experiencing an allergic or contact reaction? If the redness spreads to other parts of the body where the food didn’t touch, doesn’t start to fade away after wiping down the skin, and baby is in distress, then please do call your doctor.
