Make amazing, low carb spaghetti sauce for spaghetti squash, meatballs, zoodles, and more with this easy recipe.
Sometimes reading ingredient labels can be a real bummer. Take spaghetti sauce, for example. Prego has 9 grams of sugar in each serving, and Ragu has 8 grams of sugar! If you’re eating low-carb or want to reduce your sugar intake, that can be a real surprise.
Hubby is eating low-carb, so I wanted to make a healthier spaghetti sauce for him without added sugar. We use lots of spaghetti sauce, and not just for pasta. It’s a great dipping sauce for zucchini fritters, we top our meatball sandwiches with spaghetti sauce, and lots more.
If you’ve ever eaten a ripe tomato from the garden, you know how sweet and tasty they are. So how could I capture that sweet flavor in spaghetti sauce without adding sugar? There’s a secret ingredient that will blow your mind.
You ready for this?
We’re going to add shredded carrots to our sauce ingredients. Then we’ll cook it low and slow in the Crock Pot or quickly in the Instant Pot to meld all those amazing flavors. (If you need to make a fast stove top sauce, check out this 10-minute spaghetti sauce recipe.)
When it’s ready, you can leave it chunky and have low carb marinara sauce, or you can blend it a bit to make a more traditional spaghetti sauce texture. I like it smooth, served atop a mound of spaghetti squash cooked in the Instant Pot.
Tools Used to Make Low-Carb Spaghetti Sauce
Here are the tools I recommend to make this recipe quickly and easily:
Instant Pot: this is the safest and simplest pressure cooker I’ve ever used.
Crock Pot: if you prefer to use a slow cooker.
Susi garlic press: The Frugal Gourmet recommended this on his show when I was a teenager and I’ve used mine ever since. It’s a workhorse!
Kitchen Aid food processor: to shred the onion and carrots.
Immersion blender: if you want to puree the sauce so it’s less chunky.
