Chop onion, garlic, carrot, and celery into small pieces. Keep everything ready before cooking. This step saves time later. Fresh vegetables make the sauce taste rich and natural.

Heat olive oil in a deep pan. Add onion and cook until soft. Then add garlic, carrot, and celery. Stir well and cook for five minutes until fragrant.

Add ground beef to the pan. Break it with a spoon. Cook until it turns brown and no pink remains. This step builds the base flavor of the dish.

Mix in tomato paste and cook for two minutes. This adds a deep, rich taste. Stir well so everything blends nicely together.

Add canned tomatoes and stir. Crush them slightly with your spoon. This gives a smooth texture to the sauce. Let it simmer gently.

Add oregano, basil, salt, and black pepper. Mix well. If the sauce tastes too acidic, add a little sugar. This balances the flavor nicely.

Let the sauce cook on low heat for 30 minutes. Stir sometimes. The longer it cooks, the better it tastes. It becomes thick and rich.

Boil water in a large pot. Add salt and spaghetti. Cook until al dente. Drain and keep aside. Do not overcook the pasta.

Add cooked spaghetti to the sauce. Toss gently so every strand gets coated. This step brings everything together perfectly.

Serve hot on a plate. Add fresh parsley and grated parmesan on top. Enjoy every bite with a smile.
