Here is a simple way to make pasta sauce:

• Heat olive oil and butter in a pan, and sauté finely chopped onion until soft (about 4-5 minutes).
• Add minced garlic and black pepper, and cook for an additional minute.
• Stir in tomato paste and cook for a couple of minutes.
• Slowly add cream while keeping heat low, whisking to combine; then add lemon juice.
• Mix in grated Parmesan cheese gradually, letting it melt into the sauce.
• Add cooked pasta straight into the sauce with a splash of reserved pasta water, and let it simmer gently for a minute or two to thicken.
• Season with salt to taste, and optionally garnish with fresh basil.

This recipe creates a creamy tomato pasta sauce that is rich and flavorful, perfect for dressing your favorite pasta.

If prefer a more basic tomato sauce without cream, one can cook onions, garlic, and grated carrots in olive oil, add crushed tomatoes with seasonings like paprika, oregano, basil, and parsley, then simmer for 15-20 minutes for a fresh homemade spaghetti sauce.

Let me know if a specific type of pasta sauce is preferred, such as creamy, tomato-based, or with meat.
