To start, heat the olive oil in a large saucepan over medium heat. Add the chopped onion and sauté until it turns golden brown, releasing its sweet aroma. This step sets the foundation for the entire sauce, infusing it with a rich and savory flavor.

Once the onion has cooked to perfection, it’s time to add the ground beef. Allow it to brown, stirring occasionally to ensure even cooking. The sizzling sound and enticing aroma will make your mouth water in anticipation.

As the ground beef reaches a delightful golden brown color, sprinkle in the minced garlic and chopped parsley. These ingredients add layers of fragrance and freshness, elevating the sauce to new heights.

Now comes the star of the show – the tomatoes. Open the No. 2 can of tomatoes and carefully pour them into the saucepan. The tangy and zesty flavor of tomatoes harmonizes with the other ingredients, providing a luscious and vibrant taste to the sauce.

Unlock the flavor potential of this sauce by adding a can of tomato paste. The concentrated richness of tomato paste adds depth and a velvety texture to the sauce, intensifying the taste experience.

For those who appreciate a delightful umami taste, this step will be a treat. Open a small can of mushrooms and gently add them to the simmering sauce. The mushrooms release their earthy essence, intertwining with the other flavors to create a symphony of savory notes.

Enhance the natural flavors with the perfect blend of seasoning. Sprinkle in the salt, pepper, and marjoram, carefully measured to ensure they complement the sauce harmoniously. These ingredients bring balance and depth to the dish, making it a truly unforgettable experience.

After adding all the ingredients, pour in a cup of water to reach the desired consistency. Allow the sauce to simmer on low heat for about 30 minutes, giving the flavors time to meld together in a perfect union. The kitchen will be filled with an irresistible aroma that will make everyone eagerly anticipate mealtime.
