💭 Top tips for success
Here's s a few tip and tricks to making the best keto pizza sauce;
- If you prefer a thinner sauce, add a little water to the mix. For a thicker sauce, you can either use tomato paste instead of tomato sauce or both. Adding a tablespoon or two of Keto-friendly almond flour is the other option. Combine equal parts of water and flour, then add to sauce.
- Tomato paste typically has 2 net carbs per serving, so you should use it in moderation. If you're on a strict keto diet, I suggest you thin it with water.
- Your sugar-free pizza sauce shouldn't be too thin; otherwise, it will make your pizza crust soggy.
- Parmesan is the star ingredient. It adds a delectable flavor to this Keto pizza sauce, so don't skip it. Out of parmesan? Asiago, Grana Padano, dry Jack, and romano cheese are great alternatives you can use.
- If you like your sauces hot and spicy, add more red pepper flakes.
- Make a big batch of this flavor-packed keto pizza sauce and have it on hand whenever you want to make keto pizza crust, fathead dough, or top your favorite veggies and meats.
- Parmesan is among the saltiest cheeses, so you should refrain from adding more salt to the sauce. But if you happen to overdo the salt, you can downplay the saltiness by adding some sugar-free balsamic vinegar.
- If you want to infuse more flavor into your keto pizza sauce, try adding a small splash of olive oil or more spices and blends like Italian seasoning.

🤔 Pasta Sauce vs. Pizza Sauce
A lot of people often get confused about these two sauces. While sometimes they can be used interchangeably, they're pretty different.
Pizza sauce is basically raw, uncooked - it has that fresh tomato taste. On the other hand, pasta sauce is essentially cooked in a saucepan over low heat to develop a deep flavor. With that said, both are easy to make from scratch.
🧊 Storing and ♨️ Reheating
Leftover sauce can be stored in the fridge or freezer. It can last up to two weeks in the fridge and be frozen in an airtight container or jar for six months. When you're ready to use it, just defrost it in the fridge overnight.
I store my sauce in ziplock sandwich bags, Fill a sandwich bag about half full, seal completely, lay flat on a tray, and freeze. Once frozen, the bags are easy to stack and store. You got me! I make a lot of PIZZA.

are you suppose to simmer this? It says cook time 48 mins.
Kim
Oh boy, no LOL. I had to install a new recipe plugin and it didn't import everything exactly right. I don't cook the sauce until it's on the pizza. I fixed the recipe, thanks so much for asking about it.
Diane
Carb count would be based on how many carbs in your choice of tomatoe sauce and Parmesan cheese, I would imagine.
Pamela J Laut
I looked for nutrition information and could not find a carb count. Why are nutrition values not posted?
Kim
Tomatoes have carbs. Low carb doesn't mean zero carbs. But it does mean avoiding added sugar. Many people follow a low carb diet and still eat 100 carbs a day. It's all relative. But if you want to make pizza with tomato sauce at least you know EXACTLY what's in this one.
Megan
I agree!! Low carb doesn't mean zero carbs! Good luck finding a tomato sauce that fits into the 'zero carb' category. It probably tastes horrible. Kim, this pizza sauce is awesome!!! Thank you so much!! You are a life saver!!
Breanna Worz
How many carbs are in It? Or per serving? Great recipe, can't wait to try it.
Shawn
This Pizza sauce is the bomb! I'm not to fond of the crust substitutes out there so we go crustless! It allows this to be super quick and easy! I make extra sauce and freeze it into serving sizes. I thought I might have to add a little sugar substitute to get it close to what we were used to (before keto) but no, it's perfect the way it is. Thank you!
Kim
Thank you so much for the feedback, I appreciate you sharing your experience and I'm so glad you like it!
Tammy Simons
How many net carbs per serving, and how much is a serving size?
Michelle
What do you mean by tomato sauce in a can? Ketchup? The concentrated tomato paste? That usually contains sugars, or do you mean chopped/crushed tomatoes?
Kimberly Grabinski
Plain tomato sauce, just make sure it doesn't have added sugars. Tomatoes do have some sugar naturally so there will be sugar content on the label, just make sure sugar isn't an ingredient.
