Why you'll love this Low Carb Spaghetti Sauce
"There is something so comforting about a plate of spaghetti. I love that this sauce is hearty and full of fresh vegetables and herbs. Serve over traditional pasta or, better yet - over zucchini noodles to keep it low-carb! "
Everyone needs a basic go-to recipe for marinara, and this is IT.
Homemade marinara sauce is super simple to make, and you know exactly what is in it. Store-bought marinara is packed full of added sugar, sodium, and preservatives! Yuck!
Once you make this recipe, it will become your new favorite go-to for homemade garden-style marinara.
This marinara sauce is super easy to make, and you can use it for multiple different recipes. Use it for traditional spaghetti, lasagna, stuffed peppers, ravioli, or any of your favorite Italian dishes!
Low Carb Keto Spaghetti Sauce
Unlike your traditional store-bought spaghetti sauce or marinara, this recipe has no added sugar. That makes this recipe keto-friendly, low-carb, and gluten-free!
Healthy Spaghetti Sauce ingredients
- Extra Virgin Olive Oil - you can substitute with your favorite cooking oil if preferred. I find that extra virgin olive oil has the best flavor and is a healthier oil to use.
- Onion - medium-sized, any variety you prefer.
- Garlic - use store-bought minced garlic for ease or finely chopped fresh garlic for more flavor.
- Kosher Salt
- Ground Black Pepper
- Canned Crushed Tomatoes - you can use fresh tomatoes if you prefer, or just add some diced fresh tomatoes to your sauce for extra texture.
- Bay Leaves - are used as aromatic in the sauce. You will remove them from your sauce when it is all done.
- Dried Oregano - you can use fresh or dried in this recipe, whichever you prefer.
- Basil - you can use fresh or dried in this recipe. Using chopped fresh basil will give a brighter, fresher flavor but dried works well also!
For exact ingredient quantities, please see the recipe card below!
Healthy Spaghetti Sauce variations
Here are a few ways you can customize this recipe:
- Add a protein to your marinara sauce if you'd like to. Some suggestions would be meatballs, ground beef, ground turkey, sliced or diced sausage, or keep it vegetarian with diced tofu.
- Feel free to omit or replace any of the items in this recipe.
- If you don't want a rustic or "chunky" marinara sauce, you can use an immersion blender at the end to make the sauce smooth or to your desired consistency.
- Kick up the heat by adding some crushed red pepper flakes to your sauce. Start light-handed and add more as you like.
How to make Sugar Free Spaghetti Sauce
Start by heating olive oil in a large stock pot over medium-high heat. Add the onions first and saute until soft, about 8 to 10 minutes.
Add the garlic and saute for about 1 minute. Add the celery and carrots and saute until the vegetables are soft, about 10 minutes.
Add Remaining Ingredients
Next, add the crushed tomatoes, bay leaves, oregano, basil, salt, and pepper. Bring to a simmer and reduce the heat if needed.
Continue to simmer (uncovered) for 45 minutes to 1 hour until the sauce has reduced and thickened.
Remove Bay leaves
When ready, remove the bay leaves and discard them.
Season the sauce with additional salt and pepper to taste, and enjoy!
How to serve Low Carb Marinara Sauce
Traditionally, I serve this hearty marinara sauce with pasta for spaghetti! You can substitute with zucchini noodles or your preferred noodle alternative to keep this low-carb.
You can use this sauce in any of your favorite Italian dishes as well! I have used it on eggplant parmesan, lasagna, meatballs, stuffed peppers, and so many more.
Don't forget the french bread(that is if you are ok with the extra carbs)! Make homemade and then slather with garlic, butter, and herbs for the best garlic bread.
Meal idea! One of my favorite keto meals is these Lasagna Stuffed Peppers. Use this homemade marinara sauce in the recipe to make them even more delicious! Serve with this simple fresh green salad with Italian Dressing.
Low Carb Spaghetti Sauce top tips
- Remember to watch the heat when cooking your marinara and stir frequently. Tomatoes contain sugars that can caramelize and eventually burn on high heat.
- If your spaghetti sauce is too acidic offset with a little sugar or sugar substitute.
- For ease, buy already prepared carrots, celery, and onion at the grocery store! They are normally sold together in a clear, plastic, two-pound container found in the produce section.
- If you prefer a thicker marinara sauce, feel free to add some tomato paste to help thicken your sauce to the desired thickness!
How to store Sugar Free Marinara Sauce
To store leftovers, let the roast cool completely, then transfer to an airtight container. Store in the refrigerator for up to 4 days. See reheating and freezing instructions below.
How to reheat Low Carb Marinara Sauce
Put your marinara into a microwave-safe dish, cover, and heat, stirring every 35 seconds until you have reached your desired temperature. A small saucepan on the stove works just as well over medium heat. Bring the marinara to a simmer, stirring frequently or until the desired temperature has been reached!
How to freeze Healthy Spaghetti Sauce
Cool your marinara uncovered and transfer it to an airtight container. Freeze for up to 3 months. Portion your marinara into 2-cup portions and freeze for easy single-meal portions!
Sugar Free Spaghetti Sauce FAQs
The main difference between the two is the broadness of flavor. Spaghetti sauce is more rich and more complex, usually made with a larger list of ingredients, including beef. Marinara, on the other hand, normally does not include meat.
Yes, they sure do! This simple tomato sauce is used to dip into and onto pasta and as a base for pizzas as well.
The best substitutions for marinara are pizza sauce, spaghetti sauce, tomato sauce, tomato paste, or canned tomatoes (stewed tomatoes work the best).
