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

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™.

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.

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 chicken 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 burger, so I freeze the burgers individually, for an easy weeknight meal.

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.

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 fries
