In a large skillet over medium heat, melt the butter and add the diced onion and minced garlic. Cook until fragrant, about 2-3 minutes, then add the chunks of chicken breast, seasoning them with salt, pepper, and paprika as they brown evenly on all sides.
Once the chicken is cooked through, stir in the frozen vegetables and chicken bouillon granules, ensuring everything is well combined. Allow this mixture to cook for another 4-5 minutes until heated through.
Reduce heat to low and mix in both cans of condensed soups along with half a cup of milk. Stir continuously until everything is incorporated smoothly, creating a luscious sauce that envelops your ingredients.
While preparing your sauce, bring a pot of salted water to a boil and cook the egg noodles according to package instructions until al dente. Drain them well before adding them directly into your skillet with the creamy chicken mixture.
Gently fold in the cooked egg noodles into your creamy chicken pot pie mixture until evenly coated. Let this simmer together on low heat for an additional minute or two before serving warm.
