Preheat the oven to 375 F and line a medium-sized baking tray with parchment paper.
Add the olive oil, mint, cilantro, ginger, lime juice, cumin, red pepper flakes, salt, and pepper to a food processor. Blend the ingredients for 20 to 30 seconds to form a marinade.
Place the cod fillets into a bowl and pour the marinade over the fillets. Coat the cod thoroughly then allow it to sit for at least 5 minutes to marinade.
Transfer the cod to the prepared baking tray and bake for 20 minutes, until the cod is baked through and flaky. Serve hot.
