Start by browning the ground chicken in a large deep skillet over medium heat. You will know it is ready when it is no longer pink and starts to get a nice golden color. Make sure to break it into small pieces while cooking for even results.
Add the chopped onion and sliced mushrooms to the skillet, stirring frequently until they soften and smell heavenly. This usually takes about five minutes. Watch out for burning; you want them tender, not blackened.
Mix the flour, chicken bouillon, paprika, Worcestershire sauce, and some water in a blender until smooth. Pour this mixture into the pan, letting it thicken as it cooks. It should look creamy and coat the back of a spoon. If it is too thin, let it simmer a little longer.
Stir in the sour cream and fresh thyme once the sauce has thickened. You will notice a richer flavor developing. Do not rush; let the sauce heat through without boiling to keep that creamy texture intact.
Toss your choice of cooked pasta into the pan with the chicken and sauce, mixing well to coat everything evenly. It should look inviting. If you prefer your pasta not soggy, avoid letting it sit too long in the sauce.
Finish with a sprinkle of chopped parsley for a pop of freshness. It will brighten your dish and elevate the flavors. Serve it warm for an inviting meal that is sure to please everyone at the table.
