This Baked Split Chicken Breasts with a Port Wine Mustard Sauce has to be one of my favorite chicken dinners ever. It has the best crispy skin while still having a wonderful tender and juicy interior. Best part is that there is almost no prep time and cooks up in 30 minutes making it a quick in easy dinner after a busy day of work or play!
Of course I couldn’t help tinkering with Mimi’s original recipe – Chicken Breasts Deville. It called for lots of cans – canned potatoes, artichoke hearts, baby onions, olives, and sweet red pepper. Sorry, but no thank you. That is way too many strong flavors competing with each other. The original recipe also called for sautéing the chicken in butter. This just leaves the chicken with chewy, limp skin. I don’t know about you, but limp skin is a big no no for me.
These split chicken breasts are seared skin side down and baked in a 500 degree oven. This allows the chicken to cook quickly while still retaining moist juicy breast.
Ingredients
- Skin on, bone in chicken breasts
- Pearl Onions
- Port Wine
- Dijon Mustard
- Chicken Stock
- Lemon Juice
- Thyme
- Tarragon
- Parsley
The port wine and Dijon mustard gives the sauce the most amazing flavor and such a velvety texture. I could eat it up by itself!
