How To Make Classic Spaghetti with Tomato Sauce

1. Build the flavor base

Heat olive oil in a pan over medium heat. Add onion, carrot, and celery. Cook slowly for 8–10 minutes until soft and lightly golden.

2. Add garlic and tomato paste

Stir in garlic for 30 seconds, then add tomato paste. Cook for 1–2 minutes to deepen flavor.

3. Add tomatoes and simmer

Add crushed San Marzano tomatoes, herbs, bay leaf, salt, pepper, and chili flakes. Simmer gently for 25–35 minutes until thick and rich. Stir occasionally.

4. Finish the sauce

Remove bay leaf. Stir in butter until silky, then add Parmesan for a creamy, rich finish. Adjust seasoning if needed.

5. Cook the spaghetti

Boil salted water and cook spaghetti until al dente. Reserve 1 cup pasta water before draining.

6. Combine pasta and sauce

Add spaghetti to the sauce and toss well. Add pasta water gradually until sauce becomes glossy and coats every strand.

7. Serve

Plate the pasta, top with extra sauce, Parmesan, and fresh basil. Finish with a drizzle of olive oil if desired.
