This walnut crusted chicken uses rolled oats instead of flour to make up the breading. This makes it a great gluten free, wheat free option for flavorful crusted chicken breasts. It also uses the marinade as the binder so no eggs are involved either!
I also have provided options for the marinade for those who may be abstaining from alcohol. White wine can be used but if you don’t want to buy a bottle to also drink you can use white wine vinegar. If you don’t want any alcohol at all simply make up a little chicken broth and add some white vinegar to achieve that same mix of umami and tanginess.
If for any reason you are not using honey in your diet, which I don’t recommend because buying honey is great for bees! But if you’re not you can use maple syrup. Maple syrup and mustard go just as good together and honey and mustard. In some cases, maybe even better. Maple syrup also compliments walnuts and oats so feel free to make the exchange if that’s what you’d prefer!
Gluten free walnut crusted chicken goes great with any plenty of side dishes. The walnuts add some good for you fats to this recipe so you won’t be craving anything as heavy. I served it with these sweet and tangy roasted vegetables.
Health benefits of walnuts
Walnuts are a great source of vitamin E, melatonin, and Omega-3s. Walnuts are calorically dense but the good fats in them aid in everything from lowering your bad (HDL) cholesterol to managing brain function over time. If you are able to eat tree nuts walnuts are a great option to add some variety into your diet. This gluten free walnut crusted chicken is a great way to add walnuts without also adding other common food alllergens.
