This is, quite honestly, the only recipe for grilled chicken breasts you’ll ever need. The simple combination of olive oil, lemon, and fresh herbs creates a clean, summery flavor profile that brings out the best of lean, white meat. Fresh garlic and red pepper elevate the marinade, as well as the inherent flavor of the bird. Relative to the amount of oil and liquid going in, the amount of each aromatic called for in the marinade may seem like a lot—however, this marinade is intentionally intense by design. Using a marinade this flavor-forward allows for overall less marination, which is what you want when it comes to chicken breasts.
