Begin by heating the olive oil in a large skillet over medium heat. Once hot, add the chopped onion and sauté for about 3-4 minutes until the onion becomes translucent. Add the minced garlic and cook for an additional minute until fragrant.
Next, add the diced chicken breast to the skillet. Season with salt, pepper, and dried thyme. Cook for about 6-8 minutes, stirring occasionally, until the chicken is browned and cooked through.
Once the chicken is cooked, add the sliced mushrooms to the skillet. Cook for another 4-5 minutes, stirring frequently, until the mushrooms are tender and have released their moisture.
Add the Arborio rice to the skillet, stirring well to combine. Let it toast for about 1-2 minutes, which will enhance its flavor.
Slowly pour in the chicken broth, stirring continuously to ensure the rice is evenly coated. Bring to a gentle simmer, then reduce the heat to low. Cover the skillet and cook for about 18-20 minutes, or until the rice is creamy and tender.
Once the rice is cooked, pour in the heavy cream and stir to combine. Allow it to heat through for another 2-3 minutes. Taste and adjust seasoning with additional salt and pepper if desired.
Remove the skillet from heat. Garnish with fresh parsley for a pop of color and freshness. Serve the Creamy Chicken Mushroom Rice Skillet warm, and enjoy every creamy bite!
