If we could give this 10 stars we would. I marrinated the chicken in the oil/vinegar/cajun seasoning for about 5 hours, drained and blotted the chicken and then topped with additional cajun seasoning before baking. Topped with lite swiss cheese when mostly done. Next time will use twice as much mushrooms. Key to this recipe is using a cajun seasoning blend you like and adjust cooking time based on size of chicken breasts. Absolutely delicious! Made this on the grill tonight for a change from the normal baking after marrinating the chicken for about 3 hours. Did the mushrooms in additional vinegar and cajun seasonings in foil. The flavors really pop more on the grill, especially when hit with a squeeze of lime when serving. Thanks so much for this easy and versatile recipe.
