This delicious Cajun chicken marinade has onion and garlic powders plus Cajun seasoning and more. It’s best to prepare this about an hour before you want to cook the chicken. I’d recommend a longer time in advance for a richer flavor. If you are looking for a spicy marinade for chicken breasts, this one works really well. It isn’t that spicy but it does have a bit of a flavor kick from the Cajun seasoning. You can serve the resulting chicken with your choice of fries or rice, as well as a veggie or two. If you enjoy Spanish or Mexican rice, that would also be a good serving idea. That way you can combine both veggies and rice in a single side dish. This Cajun chicken marinade is perfect for cooking novices because it’s really easy to prepare.
