WW Recipe of the Day: Simple Low Carb Tomato Sauce

Fresh tomato sauce is one of my long time staples because it is so versatile. The problem with many jarred marinara sauces is that they contain added sugars and fat. 

This low-carb, low-fat, gluten free version is as tasty as any recipe I’ve made to date and is equally home under, over and in a variety of dishes from chicken to pasta to keto pasta to spaghetti squash.

Besides being low carb and high flavor, because it is free of added fat (such as olive oil) and sugar, this simple tomato sauce is also low calorie so it’s basically guilt-free too.

Any leftovers freeze beautifully so are ready to go when needed.

Recipe Notes

I normally like tomato sauce that’s a little chunkier rather than a smooth puree. I enjoy the texture—however if you prefer a smooth sauce, just process a few seconds longer and it’s done.

Any canned tomato will work with this—I used whole, plum ones without additional salt, adding salt to taste at the end of the cooking.

The recipe calls for a large pinch of dried crushed red peppers. Increase the amount for more heat or skip it if you prefer less spice.

This sauce makes an instant elegant finish to any grilled meats like chicken breasts or fish fillets. Naturally, it’s good on pasta and as a base for baked dishes like lasagna. Turn it into meat sauce by stirring it into ground beef, turkey, chicken or pork. 

Toss the garlic and quartered onion in the processor and make one step of mincing both by pulsing both for a few seconds. Add them, un-chopped to the processor when blending; it’s easier and they will chop up quickly.

Here’s another good trick. Pour the whole tomatoes into the pot. As they begin to cook, use a kitchen shears to roughly chop them up. It’s easy and avoids any mess.

Serving Suggestions

This is an easy tomato sauce with a rich and satisfying taste, so serve simple side dishes like a tossed salad or grilled veggies. A spoonful of the sauce on the veggies is also delightful.

Ways to Use Leftover Tomato Sauce

Freeze the leftovers in small 1/2- to 1-cup containers so you can pull out just the right amount when you’re ready to use it.
