Cook the spaghetti
Bring a large pot of salted water to the boil. Add the spaghetti and cook according to the packet instructions or until cooked al dente.
Onion and Garlic
Place a pot over medium-low heat. Add olive oil to a hot pot. Add the diced onion and diced garlic. Cook for a few minutes until the onion is nice and soft.
Cook the sauce
Add grated carrot and cook for about 5 minutes. Grated carrot cooks quicker than the sliced one. Add balsamic vinegar, 1/2 teaspoon oregano, and pepper. Stir, then add the tomato passata and cook for about 5 - 7 minutes to reduce the sauce.TipYou will see sugar in a lot of marinara sauces but we decided to add carrot to the sauce which adds a lovely, natural sweetness to the dish and it is a good substitute for sugar in this recipe.
Finish and Serve
Pour about 100 ml of reserved pasta water to the Marinara sauce. Stir to combine, then add your al dente cooked spaghetti. Season to taste with salt and pepper. Serve with freshly grated parmesan cheese, a drizzle of olive oil and some fresh oregano and/or basil.
