Salsa Verde walked so that Pesto could run. But seriously, every time I serve something with salsa verde someone asks me if it’s pesto. NOT EVERY GREEN HERB SAUCE IS PESTO Y’ALL!!!
Pesto is to pasta as salsa verde is to proteins. It’s similar in that the foundation of the mixture is chopped herbs and olive oil, but salsa verde is inherently acidic making it the ideal accompaniment to basically everything. You honestly could put it on pasta like you would pesto. That would be lovely. But my preferred usage is to top meat and fish to brighten and lift all of the flavors with out masking them.
I’ve been known to take a tablespoon of salsa verde and turn it into a vinaigrette for salads and veg. Or combine it with a stick of softened butter for an instant garlic herb infused butter situation. It is so multifunctional and adaptable, I have a container of this stuff in my fridge at all times.
