Heat olive oil in a large skillet, then add the ground turkey. Season with salt, pepper, and thyme. Cook while breaking it into small pieces until it’s browned and cooked through. This gives the dish a savory base.
Add the mushrooms and onions to the same pan, letting them soften and caramelize slightly. Once the mushrooms release their juices and brown lightly, stir in the garlic and cook just until fragrant.
Pour in the orzo and chicken broth. Give everything a good stir, then bring it to a gentle boil. Lower the heat and let it simmer until the orzo is tender and most of the broth is absorbed. Stir occasionally to prevent sticking.
Reduce the heat and pour in the heavy cream. Stir well, then add the freshly grated Parmesan cheese. Let it all blend together into a creamy, smooth.
Once everything looks creamy and luscious, remove the pan from heat. You can stir in some fresh herbs like parsley if you want added brightness. It should look rich, hearty, and perfectly creamy.
