Low Carb Zoodles and Meatballs

A few of my absolute favorite go to recipes for this Marinara based sauce are Spaghetti Bolognese, Low Carb Italian Baked Meatballs ,Low Carb Zoodles and Meatballs , and Chicken Parmigiana. Being such a versatile recipe, there really are so many ways you could use it.

Many people think that Marinara Sauce means it’s a seafood sauce. Marinara does not become seafood marinara until seafood is added to it, and is actually a simple tomato based sauce. Because of this it’s perfect to use as a base for pizzas and is also fantastic when used in in this recipes such as Eggplant Parmigiana. Make sure you also heck out the recipe below for some really simple ways to vary this sauce. Add a few additional ingredients and it’s easy to turn this sauce into a Puttanesca or Arabiatta sauce.

Marinara Sauce is often made in my house on “clean out the fridge day”. I add all of the vegetables that I didn’t get around to eating during the week that are suitable to using in the sauce. Come the end of the week and I always seem to have capsicum, mushrooms, eggplant and zucchini left in my fridge. I hate wasting food, so it’s fortunate that these vegetables go really well in this sauce.

Use this sauce fresh or freeze it into portions for convenience. Serve it as an instant vegetarian pasta sauce or add some meat to it, and you have a delicious meal. Try it as the base for Low Carb Eggplant Lasagna for one of my favorite ways to use it. These are nutritious, easy to make meals, that can be thrown together in a little time, which is why I love this recipe.

Any wine that is past its use by date is put in a small plastic bottle in the freezer in my house. Don’t stress about forgetting to defrost the wine in cooking, as wine defrosts really quickly. Just squeeze the frozen wine out of the bottle straight from the freezer and it generally sludges out. Some use ice trays to do this but I find a small bottle much easier to store and more practical. Even though you can use either red or white wine in this recipe, my favorite is red wine. As red wine cooks off, it imparts a delicious flavor and amazing aroma. My family love the taste of this made with red wine and they let me know when I haven’t used it.

Tinned tomatoes are so easy to use for this recipe out of convenience, but make sure they are sugar free. Fresh tomatoes can be used as well. Sometimes I use half tinned and half fresh tomatoes. Some don’t like to use the pulp from fresh tomatoes as it thins the sauce out. I hate waste, so use them, and simply simmer the sauce for longer to thicken it up.

Should you ever want to use fresh tomatoes without the skin; there is a really easy way to remove the skin. Simply slice into the skin with a knife, breaking the entire surface but not going in too deep. Make 4 segments or quarters from the navel (do tomatoes have a navel??) like a large orange segment. Drop the tomato into boiling water for approximately 30 seconds. Plunge it into ice cold water and you should be able to peel the skin off easily. Sometimes you have to repeat this for less ripe tomatoes, as the skin can be tougher. Generally I tend to use overripe tomatoes in sauces like this anyway, so it’s generally not a problem. For more details on how to cut the tomato have a look at the photo I’ve attached above.

I hope you come up with some delicious ways to use this sauce, and I hope the carb lovers and the low carbers alike in your house, enjoy these recipes. The thing I love about pasta sauce is that zucchini zoodles are so easy to make, so that when my family eat their traditional pasta, no one ever has to miss out. When you have a lovely, simple to make tomato sauce like this on hand, dinner can be as simple as stirring some of the sauce through some hot zoodles, and topping with some freshly grated Parmesan cheese. Pan fry some minced beef and add some of the sauce for a slightly more substantial pasta sauce, that is really easy to throw together.

    I love this recipe. Its such a good basic tomato sauce that I use in everything. I’m working my way through your suggested recipes by the way and have made the parmigiana and the meatballs so far. Thanks so much for sharing.

  3. thanks so much for this one.. i always get the canned tomatoes which have the least amount of sugar per 100 grams but wondering if there is a sugar free version somewhere I am missing please… would love to know

    1. Thanks Leanne. Where do you live? If in Australia, most cans in the stores are sugar free so checking the ingredients list as well as check the carbs on the label before you buy is the right thing to do. I often buy the generic brands from Coles and Woolworths and also like the organic tinned tomato from Aldi, all of which are sugar free. Tomato is high in carbs though so as long as you aren’t eating a lot of it every day you should be fine.
