How to make the best authentic Italian Tomato Sauce recipe from scratch – Easy, rustic and flavorful, it takes only 5 ingredients and 30 mins to recreate a staple of Italian cuisine at home.


This classic Italian tomato sauce is as tasty as it is easy to make, and it’s the foundation of so many traditional Italian dishes.

Loved by kids and grown-ups, tomato sauce is actually one of the 5 mother sauces in the culinary arts, which are the bases for all the other sauces.

Around the world it’s simply called pasta sauce, however, in Italy is called salsa al pomodoro (which means tomato sauce).

Growing up in an Italian kitchen, with my mum cooking tomato sauce at least 3-4 times a week, for me making classic Italian tomato sauce is a no-brainer. But I’ve seen out there that the struggle is real.

Some people add a generous amount of sugar, others use tomato puree or passata, and I’ve actually seen a few friends adding ketchup (WHAT?!).

Believe me, if you’re looking for the authentic Italian tomato sauce recipe you don’t need any of the above.

The Difference Between Marinara Sauce and Tomato Sauce

First of all, let’s start by saying that there’s a huge difference between marinara sauce and tomato sauce.

Marinara sauce is not cooked, and dried oregano is usually added into the mix.

This sauce is often called pizza sauce, because, guess what, it’s used for making pizza.

Tomato sauce, on the other hand, is slowly simmered, and onion, basil leaves and a bay leaf are usually added in.

This sauce is used as a base for pasta, eggplant parmesan, meatballs, eggs in purgatory, and many other dishes.

The Real Italian Tomato Sauce Calls For Just 5 Ingredients

To make a REAL authentic Italian tomato sauce all you need is just 5 ingredients:

  • whole canned plum tomatoes (or fresh tomatoes)
  • red onion
  • basil leaves
  • bay leaf (or a pinch of sugar)
  • extra-virgin olive oil

Most Italian mammas and nonnas add a garlic clove. My Italian mum adds it, and so do I. But it’s totally optional, so if you’re not a garlic fan, simply omit it.

Using the right ingredients is crucial for making the best Italian tomato sauce.

Opt for organic ingredients whenever possible, don’t skip on the fresh basil leaves, and use high-quality extra-virgin olive oil.

Fresh Tomatoes or Canned Tomatoes?

If you’re using fresh tomatoes (which I highly recommend when they’re in season), you need to blanch the tomatoes in simmering water for a couple of minutes, then peel the skin off and proceed with the recipe.

The best fresh tomatoes for a classic Italian tomato sauce are:

  • Roma tomatoes, meaty, easy to peel, and with very few seeds
  • Cherry Tomatoes (ciliegino), are small, round and really sweet
  • Datterino Tomatoes, are also very small and delicately sweet

It’s not easy to find super tasty tomatoes these days, especially if you don’t live in Italy. So I mostly use properly-good canned whole tomatoes.

If you’re opting for canned tomatoes, the best ones to look for is the San Marzano variety.

This variety grows in Italy, in the Campania region, and has been awarded the PDO (protected designation of origin) status. 

San Marzano tomatoes have a long shape, bright red colour, easily peelable skin, meaty pulp, and very few seeds.

Their flavour is not too sweet and not too bitter, which makes them incredibly versatile, both for cooking and using them raw.

These are the very best tomatoes to use for making Italian tomato sauce, or the classic marinara sauce for Neapolitan pizza.

How do you take the bitterness out of tomato sauce?

Let’s start by saying that what makes tomato sauce bitter is the tomato itself.

Canned tomatoes are usually more bitter than fresh ones, so here’s the little trick Italians use to take the bitterness out of the tomato sauce.

Simply add a pinch of sugar whilst cooking up your sauce. Even better, add a bay leaf, it will give your sauce the perfect sweetness balance.

Make sure you remove as many seeds as you can from the tomatoes, as they also add bitterness to the sauce.

How To Make Italian Tomato Sauce

The perfect tomato sauce takes a little patience to make, but it’s definitely worth it. The secret lies in slowly simmering the sauce for about 20-30 minutes.

It will slowly reach a creamy but still a bit chunky texture, and the right balance of sweetness and savoury.

Start by slicing in half your canned tomatoes lengthwise. Remove as many seeds as possible, then chop the tomatoes into small chunks and set aside.

Don’t throw the juice in the cans away, as you will need it later.

Your authentic Italian meal will be ready in less than 30 minutes, with very little effort!

Ingredients

  • 2 cans organic whole plum tomatoes (400gr each)
  • 2 tbsp extra-virgin olive oil
  • 1 medium-small red onion finely minced
  • 1 garlic clove gently crushed (optional)

  • Add in a couple of basil leaves and a bay leaf (or a pinch of sugar), season with sea salt and freshly-cracked black pepper to taste, and gently cook all the ingredients for a further 5 minutes.
