Gather all of the ingredients needed for the Grilled Herbed Dijon Mustard Chicken Breast recipe.
Place the olive oil, vinegar, Dijon mustard, lemon juice, and brown sugar into a mixing bowl and mix well. Add your spices and garlic to a mortar and pestle and grind them to a fine paste. Then, incorporate that paste into the brown sugar mixture.
Add the chicken breast. Let it marinate for 2 hours. Remove the chicken from the marinade, season it with salt and black pepper, and then insert the Probe into the side of one of the chicken breasts.
Open the oven Door. Place the Grill onto the Grill/Griddle Rack and slide it into Position 3. Press Menu, then turn the Select dial to Menu Preset 41 (Grill in 3 Stages). Press START/PAUSE to begin preheating.
Once preheated, the oven will beep twice, display “Ready”, countdown for 10 seconds and then beep once to give you time to place your food in the oven.
Spray the Grill with nonstick cooking spray and then place the chicken breasts on the Grill. Close the oven Door and begin Stage 1 (Grill at 450˚F) for 2 minutes, after which the oven will beep once and move on to Stage 2.
The oven will remai in Stage 2 (Grill at 300˚F) to an internal Probe temperature of 130˚F. It will then beep once and move onto Stage 3 (Broil at 500˚F) to an internal Probe temperature of 155˚F, after which the oven will double beep 3 times.
Open the oven Door. Remove the chicken breasts and tent with foil, leaving the Probe in to monitor carryover cooking to 165°F. When the carryover target temperature is reached, the oven will beep three times and display “END”. Serve and enjoy.
