What makes pesto so crave-worthy?

This zesty Italian sauce packs huge flavor into just a few simple ingredients like basil, olive oil, garlic, pine nuts and parmesan. Each bite delivers a bright, herbal, nutty, salty-umami punch that makes your taste buds dance.

In fact, North America is cited as a significant market for pesto sauces, fueled by the popularity of Italian cuisine and demand for premium/gourmet food products. (ref)

When incorporating pesto, like in this Creamy Pesto Chicken Zucchini Bake, you get an automatic flavor boost. The vibrant green sauce adds layers of fresh basil, rich olive oil, salty parmesan and a nutty undertone.

Substitutions

For a lighter option, substitute half & half or milk for some of the heavy cream. Grilling or broiling the zucchini first will add charred, smoky flavors. 
A quality store-bought pesto can save time over making it from scratch – just blend in some extra fresh basil if desired.
