Preheat oven to 400 degrees F. Line a shallow baking pan with aluminum foil; spray with non-stick cooking spray.
In a small non-stick frying pan over low heat, add olive oil and heat until hot. Add garlic and cook 2 to 3 minutes until garlic begins to soften (be careful not to let garlic brown). Remove from heat and stir in brown sugar, orange marmalade, salt, and pepper until well blended.
Place chicken breasts halves in prepared baking pan; spread garlic mixture evenly over chicken.
Bake approximately 20 minutes or until a meat thermometer registers an internal temperature of 165 degrees F. (juices will run clear when cut with the tip of a knife). Remove from oven and transfer onto a serving plate.
Serve immediately.
Makes 2 servings.
* I like to use the Smucker's brand of marmalade.
**The U.S. Department of Agriculture, as well as food agencies in the United Kingdom and elsewhere, advises against washing poultry. Rinsing chicken will not remove or kill much bacteria, and the splashing of water around the sink can spread the bacteria found in raw chicken. Cooking poultry to 165 degrees Fahrenheit effectively destroys the most common culprits behind food-borne illness.
