Begin by seasoning the chicken breasts with thyme, salt, and black pepper. In a skillet, heat the vegetable oil over medium heat and sear the chicken until it is golden on both sides.
For Chicken Preparation:
Drain the sliced pineapple, making sure to save the juice for the sauce. In a small bowl, combine the cornstarch with two ounces of the reserved juice and mix well.
In a separate bowl, blend the remaining pineapple juice with Dijon mustard, honey, and minced garlic until fully combined to create the sauce.
Cooking the Chicken:
Add the sauce mixture to the chicken in the skillet, lower the heat, and cover. Let it simmer for around 15 minutes to let the flavors meld.
Once the chicken is cooked through, take it out of the skillet and keep it warm. Stir the cornstarch mixture and add it to the skillet. Increase the heat and stir for about 2 minutes until the sauce thickens.
Reduce the heat and return the chicken to the skillet, turning it a few times to coat each piece evenly with the sauce.
Place the pineapple slices around and on top of the chicken, covering it to warm everything together for an additional 2 to 3 minutes.
Serving:
Serve your delicious pineapple chicken hot over a serving of fluffy rice. Enjoy this sweet and savory dish that will surely brighten up your dinner table!
