Heat olive oil in a large pot over medium heat.
Season the chicken thighs with salt and pepper, then add them to the pot.
Brown the chicken on both sides, about 6-7 minutes per side. Remove and set aside.
In the same pot, add the diced onion and cook until translucent, about 3-4 minutes.
Add the minced garlic and cook for 30 seconds until fragrant.
Stir in the cherry tomatoes, orzo, chicken broth, and dried herbs.
Return the chicken to the pot; bring to a gentle simmer.
Cover and cook for 10-12 minutes, or until the orzo is tender and the chicken is cooked through.
Stir in the heavy cream and mix well to combine everything.
Taste and adjust seasoning; serve warm and enjoy!
