Heat the olive oil in a large skillet over medium-high heat. Once hot, add the bite-sized chicken pieces. Season them generously with salt, pepper, dried thyme, and parsley. Cook the chicken for about 5-6 minutes, stirring occasionally, until it's browned on all sides and cooked through. Remove the chicken from the skillet and set aside.
In the same skillet, lower the heat to medium. Add the diced onion and sauté for 3-4 minutes until translucent. Stir in the minced garlic and cook for another 30 seconds until fragrant, being careful not to burn it.
Pour in the chicken broth and bring it to a gentle boil. Once boiling, add the egg noodles and frozen peas and carrots mix. Stir to combine, then reduce the heat to a simmer. Cover the skillet and let the noodles cook for about 7-8 minutes, or until tender. Stir occasionally to prevent noodles from sticking to the bottom.
Return the cooked chicken to the skillet. Stir everything together and let it cook for another 2-3 minutes to marry the flavors. If you’re using heavy cream, stir it in now to enrich the sauce and give the dish a creamy texture. Adjust seasoning with extra salt and pepper if needed.
Once everything is heated through and the noodles are perfectly tender, remove the skillet from the heat. Serve your Homestyle Chicken and Noodles Skillet straight from the pan for a rustic presentation. This dish pairs beautifully with a simple green salad or crusty bread to soak up any extra sauce.
