How to increase flavour intensity in this recipe? I am thinking of making dinner tonight (probably pasta) and the ingredients that I have a courgettes, tomatoes and half a butternut squash. I am 70% vegetarian

I first added olive oil, then fried onions and garlic, then added in the vegetables. I added in salt, pepper, souvlaki seasoning, sage and thyme I believe for extra taste. At the end I mixed in a tablespoon of Ricotta (my favourite cheese). The pasta I had with it was Rigatoni.

However the taste turned out to be a bit bland. What can I do to spice up this recipe? I want it to be more intense,perhaps roasting the vegetables first and then frying them. Will that help? Otherwise what can I add to increase its taste?

Thanks.

Edit : Instead of having pasta with this sauce, can I have Ciabatta baked in the oven with it?
try adding some green, yellow and red peppers with the added vegetables. I believe these peppers give a strong taste.

Also you could try to add some paper laurel when cooking, then remove it upon serving, it gives a good taste and smell too.
