Magic behind Buttermilk Oven Fried Chicken

If you’ve been following along with me, you know that I’ve fallen head over heels in love with this incredibly crispy oven fried chicken, it’s just so easy to make and so much healthier!

Plus, no flour or eggs required, only a buttermilk marinade and a simple coating made with easy ingredients.

I like to make my own as it literally takes 5 minutes. All you have to do is mix the milk with lemon juice and allow to set for 15 minutes.  buttermilk oven fried burger with spicy mayo with sweet potato fries and a2 milk bottle in backgroundSince I’m also dairy-intolerant,  making my own buttermilk means I can also make sure its naturally free-from the A1 protein, so I always use easy-to-digest a2 Milk™. Since switching to a2 Milk™ my symptoms have reduced significantly. The award-winning a2 Milk™ is pure cows’ milk, which is naturally free from the A1 protein, so it’s a lot easier for me to digest and gentle on my sensitive tummy.

Back to the crispy chicken tenders. The secret is a special coating mix that makes this baked chicken just as crisp as deep fried. It comes together in a few seconds, all you have to do is mix together cornflakes, panko breadcrumbs, a little bit of oil and a couple of optional seasonings. a2 milk bottle, coating mix, chicken tenders and buttermilkI get the tenderloins into the buttermilk marinade the night before (it takes 3 minutes really!), and then coat & bake them whilst I prep the rest of the burger ingredients. It all comes together easily in 30 minutes max, start to finish.

I also like to make a big batch of this oven fried chicken, so I can enjoy it on its own, then use the extra pieces for making this AWESOME chicken burger.

Spicy Mayo Sauce That is Totally Addicting

Delicious homemade mayonnaise ( but you may use good-quality store-bought) with a fiery spicy kick, makes the perfect oven fried chicken burger companion. You can choose the amount of heat you want, I personally don’t like extra spicy things so I’ve kept mine on the low level, but you can definitely make it as spiced as you like.Buttermilk Oven Fried Chicken Burger with spicy mayonnaiseSimply mix garlic, mayonnaise, and sriracha sauce in a small bowl, add finely chopped pickles if you like, cover and chill until needed.

Go Crazy With The Toppings

I’ve kept my Oven Fried Chicken Burger really simple using super common toppings such as lettuce, tomatoes and red onion, and served it with sweet potato fries. BUT, that doesn’t mean that you have to!

Avocado, mushrooms, slaw, mustard, homemade ketchup, or any other of your favorite toppings and sides will surely work well, just customize your burger to suit your tastes and make it your own!buttermilk oven fried burger with spicy mayo and sweet potato friesDID YOU MAKE THIS RECIPE?
