How can i make my homemade pasta sauce deeper and less sharp?

I've been trying to get my homemade pasta sauce to have that deep, rich flavor I love in restaurants, but it always tastes a bit thin and sharp. I simmer it for a long time, but I feel like I'm missing something to really make it sing.

That deep flavor is usually a mix of long time, good fats, and a touch of umami. I once spent a whole afternoon with a gentle simmer and a spoon of tomato paste to deepen the color. It still felt sharp until I did a slow reduction and finished with a thin drizzle of olive oil at the end. It sounds simple but it helped me notice where the brightness came from and where the bite stayed.

I do not rely on one trick only. I sometimes balance sharpness by a pinch of sugar as it reduces, and I keep the sauce simmering until the flavors mingle. A tiny amount of anchovy paste can add depth without tasting fishy if you keep it subtle.

Sometimes I drift from the stove and worry I am chasing something that is not there. I fried onions until they nearly burned, then dumped in tomatoes and watched the color change. It helped a bit but I kept wondering if I was feeding the wrong thing or if the problem was elsewhere like salt balance or the pasta itself.

Could the real issue be the base you start with and how you finish it with heat and salt?
