ingredients
You don't need much for this recipe! Just a handful of items from the local farmers' market or grocery store.
- Extra Virgin Olive oil - I like to use olive oil but any kind of neutral keto or low carb compliant oil such as avocado oil, is okay to use.
- Fresh Garlic cloves.
- Tomatoes - Roma, and cherry tomatoes are the most common varieties that I use when making tomato sauce, but simply use any type of tomatoes you have in hand. If making this recipe using canned tomatoes, then use a good-quality brand such as San Marzano (not sponsored).
- Onion - I like to use an onion to lend some flavor to the sauce. Add it quartered to the simmering sauce then remove it once cooked. This means you do not have to worry about it increasing your net carb count and spoiling your keto diet.
- Fresh Basil - similar to the onion, add a large sprig of basil, which you can then remove later once the spaghetti sauce is cooked through. I also like to reserve a few leaves which I then finely slice into ribbons, and use as garnish.
- Oregano - If you can, use fresh oregano to deliver the best flavor, but the dried spice also works well.
- Red chilli pepper flakes.
- Half a cup of water.
- Salt.

how to make hearty marinara sauce
Making your own hearty marinara sauce from scratch has never been easier. And while easy marinara sauce is traditionally made using fresh peeled tomatoes, you can still make them using canned tomatoes as follows:-
Method 1: Using Fresh Tomatoes
- We start by peeling the tomatoes. Boil some water, give each tomato a little X-shaped scar at the top, then give them a quick dip in the hot water for about a minute.
- While the tomatoes boil, we prepare a bowl of icy water. Once done, use tongs to move the tomatoes into the cold bath for easier peeling.
- Let them cool a bit, then move to a board. Peel, deseed, and quarter them. The skin should slide right off!
- Put the peeled tomatoes in a bowl and crush by hand. Then, heat a saucepan on medium, adding olive oil and slivered garlic.
- Once the garlic has briefly sizzled, we then add the crushed tomatoes, water, salt, chili flakes, oregano, onion, and basil; stir. Cover and simmer on low, stirring occasionally.
- Add more salt if needed, garnish with some thinly sliced basil leaves and serve.
Method 2: Using Canned Tomatoes
- Crush the canned tomatoes in a bowl with your hands, following the Italian tradition of hands-on cooking (see useful tips below).
- Once the tomatoes are crushed, continue from the '' the rest of the steps in Method 1 above (i.e., beginning with sautéing the garlic, followed by adding the tomatoes and seasonings, simmering until cooked, garnishing, and then serving).

useful tips
- I do not recommend using a cast iron skillet or a metalic pot as the tomato sauce may end up having an acidic taste.
- Don't skimp on the olive oil. Olive oil is essential for flavor and texture.
- This is a true Italian recipe where the use of hands in cooking is very common. Just think about all the wonderful dishes that we make using our hands, starting with pizza!
- For a non-traditional marinara and considering tomatoes' varied acidity, you can add 1-2 tablespoons of sugar, sugar-free sweetener (for keto), or a cup of grated carrots to cut the acidity of the tomatoes. Similarly, thicken the sauce by using grated carrots or half a teaspoon xanthan gum (for those on a low-carb diet).
- For variation, throw in some anchovies, capers, olives or your favorite seasonings and herbs for a variation in the flavor! Add about half a cup of red wine for a depth in flavor, but keep an eye on the net carb count, if on a low-carb diet! This sauce is even tastier when made a day ahead.
serving suggestions
Let's start with the classic ways of serving it:-
- pasta: toss it with your favorite pasta, be it spaghetti, penne, or ziti, and sprinkle with freshly grated Parmesan cheese.
- meat: use as a base for meatballs or pour over grilled chicken or fish for added depth and flavor.
- Use it when making your homemade pizza.
- Serve it warm as a dipping sauce alongside some garlic bread, breadsticks, or mozzarella sticks.
- For a hearty meal, use it as a filling for lasagna, stuffed bell peppers, or eggplant rollatini.
For those on special diets, it goes well with mashed cauliflower, spiralized vegetables, such as zucchini and carrots. As always, do not let this limit you, feel free to serve it with your favorite dishes!
storage
Make great use of the bountiful tomato harvest in summer by making this homemade recipe ahead, then storing it in the fridge or freezer! Just make sure to use clearly labeled BPA-free containers, clearly marked with best-by dates.
- This sauce will keep fresh in the fridge for four to five days. To prevent the marinara sauce from staining your container, spray the insides of the container with cooking spray before filling. You can read more about how to store food and leftovers in the fridge here.
- To freeze, just fill the tomato sauce into airtight containers and store it in the freezer. This sauce will keep in the freezer for four to six months.
frequently asked questions
Hearty marinara sauce is a tomato-based sauce with a chunkier consistency and a more pronounced flavor than traditional marinara sauce. It is typically made using whole peeled tomatoes that are crushed by hand, and occasionally using canned whole tomatoes . This gives the sauce a chunkier texture and a richer flavor. Hearty marinara sauce may also contain other vegetables, such as onions, carrots, celery, or peppers.
Add two tablespoons of cassava or wheat flour to a small bowl and combine this with six tablespoons of water to form a paste. Pour the paste into the marinara sauce then stir, until the desired thickness is attained. Use half of a teaspoon of xanthan gum mixed with 6 teaspoons of water for keto and low carb.
Other ways to thicken the sauce:
Stir in chopped vegetables such as zucchini and carrots halfway through cooking, and allow the vegetables to simmer with the rest of the ingredients, or simply add mashed potatoes or celery root to the cooked sauce. You also want to simmer the sauce for at least 25-30 minutes. This helps the thicken the sauce, and develop the flavors.
You can tell it is cooked through when the oil separates from the tomato mass and floats on top of the sauce. Also, the cooked sauce will have an orange-red color and taste less tangy as the heat helps cut down the acidity.
When used in moderation, tomatoes can be eaten on a keto or low-carb diet. Just be careful with store-bought or ready-made sauces, as they do tend to come packed with added sugars and preservatives.

📖 Recipe
Hearty and Easy Marinara Sauce
Ingredients
- 28 ounces tomatoes - about 794 grams (or canned, whole tomatoes)
- 1 red or white onion (halved or quartered)
- ¼ cup extra virgin olive oil (alternatively, you can use any low-carb or keto-compliant oil such as avocado oil)
- 6 cloves garlic (slivered)
- 1 large sprig basil leaves (plus a few leaves cut into thin ribbons, to garnish)
- 1 teaspoon dried oregano
- 1 teaspoon red chili flakes
- 1 teaspoon salt
- ½ cup water
Instructions
Using Fresh Tomatoes
- Start by peeling the tomatoes. To do this, boil some water in a pot then use a sharp knife to make X-shaped cuts at the top of each tomato. Next, place the fresh tomatoes into the pot for about 60 seconds.
- Meanwhile, separately fill a large bowl with ice-cold water. Use kitchen tongs to carefully remove the tomatoes from the pot and slide them into the bowl with the ice-cold water. Peel and deseed the tomatoes (the skin should now easily come off).
- Transfer the tomatoes to a chopping board, allow to slightly cool then chop into quarters. Next, place the peeled tomatoes in a large bowl and use your hands to crush them.
- Set the saucepan to heat under medium heat. To the pan, add the olive oil and slivered garlic. Allow the garlic to sizzle for about a minute, then stir in the fresh tomatoes, onion, water, salt, red chili pepper flakes, oregano, and the sprig of basil, then stir.
- Reduce the heat to a low, cover, and cook for a further 25-30 minutes, stirring from time so the marinara does not burn. I recommend covering as it helps the tomatoes to sweat, so they break down easily. Once cooked, remove the basil and onion and set them aside in a bowl.
- Add more salt if needed, garnish with some thinly sliced basil leaves and serve.
Using Canned Tomatoes
- Transfer the canned tomatoes to a bowl then crush them with your hands. This method yields a hearty marinara sauce. If you prefer a smoother consistency, use a hand blender.
- Once the tomatoes are crushed, continue from step number 4 above in how to make the sauce using fresh tomatoes (i.e., sautéing the garlic, adding the tomatoes and seasonings, simmering until cooked, garnishing, and serving).
