Recipes just don’t get much easier than this tasty meal.  It takes about 5 minutes on the stove top and then finishes up in the oven to make meal prep super easy.

This garlic lemon chicken has an amazing sauce that is tart and savory. It's ready in about 30 minutes and is easy to prepare.

I love a tangy lemon sauce on just about anything.  It is bright and fresh and helps to make a really flavorful sauce. (Check out my chicken piccata recipe . It combines lemons with capers and artichokes for a sauce that is amazing.)

Today it is the fresh herbs that add to the flavor.  I grow fresh herbs for cooking all year round and the flavor they add to dishes is so much more intense than dried herbs. Fresh basil and thyme combine with a coarse grain mustard and lemons for a really great taste.

Time to make this Garlic Lemon Chicken

The first step in this recipe is to make the lemon mustard rub for the chicken. It is made with the coarse grain mustard, some lemon zest, sea salt, half the olive oil and the fresh herbs.  Preparing the lemon mustard rub

Just combine it all and then spread it over both sides of the chicken pieces.  I used boneless, skinless chicken and cut each breast in half to give me four portions.Mustard lemon rub for chicken

The garlic is cooked in the oil and butter for a few minutes until the edges of it start to brown, and then the chicken pieces are added and cooked for a couple of minutes until they brown nicely.Cooking chicken in oil and garlic

Now let’s  make the sauce for the garlic lemon chicken.

The sauce is so easy to make. Just combine the chicken stock with lemon juice and lemon zest in a bowl and pour it over the browned chicken pieces.Making a lemon sauce

Next, I combined a bit of water with a tablespoon of flour and then poured some of the lemon mixture into the flour paste.  It gets stirred back into the sauce and the heat is turned up to let it boil for a few minutes to let the sauce reduce a bit and thicken slightly.Add lemon juice and chicken sauce to the pan

The final step is to transfer the chicken pieces to an oven proof baking dish, pour over the mustard lemon sauce and bake in a preheated 400 º F oven for about 25 minutes.Baked Garlic lemon chicken

Tasting the lemon garlic chicken

This chicken has a bright fresh taste that is just amazing. The whole grain mustard gives both sauce and the chicken pieces a nice tang and the the lemon adds a great burst of freshness to it, too. It tastes a lot like a white wine sauce but has no alcohol in it.  Tasting garlic lemon chicken

Serve the chicken pieces with some herbed crusty garlic bread (to sop up those juices) or over a plate of noodles to allow the sauce to coat them.  The main thing is to be sure to have a way to use up all the sauce. It is THAT good!Plate of lemon garlic chicken

There are so many layers of flavor to this dish.  The herbs give a freshness to the dish and combine so well with the tart lemon flavor.  Coarse mustard adds a savory tang that compliments the garlic and the tender chicken pieces sit under a sauce that makes you want to have a spoon to eat it all!
