Prepare the Chicken: Season the chicken breasts with salt, pepper, and garlic powder on both sides.

Sear the Chicken: In a large skillet, heat olive oil over medium heat. Add the chicken breasts and cook for 5-7 minutes per side, until golden brown and cooked through. Remove from the skillet and set aside.

Make the Creamy Sauce: In the same skillet, melt butter over medium heat. Add the minced garlic and cook for 1 minute, until fragrant. Add the chicken broth and bring to a simmer, scraping the bottom of the pan to release any browned bits.

Add the Cream and Cheese: Stir in the heavy cream, Asiago cheese, and Parmesan cheese. Cook for 3-4 minutes, stirring occasionally, until the sauce thickens. Add the dried thyme and adjust the seasoning with salt and pepper.

Combine the Chicken with the Sauce: Return the cooked chicken breasts to the skillet, spooning the creamy sauce over the chicken. Simmer for an additional 2-3 minutes to warm the chicken through and allow the flavors to meld together.

Serve: Garnish with fresh parsley and serve the creamy Asiago chicken with your favorite side dish. Enjoy!
