Green chilies do contain carbs, but it takes quite a lot of chilies to get these carbs. One cup of green chilies contains about 6g total carbs and 4g net carbs. An entire green chile chicken casserole uses only one cup of diced green chiles which means that each serving is only 1 total gram of carbohydrates. Green chilies also contain vitamins C, B6, A, potassium, copper, and iron along with amino acids and phytonutrients which makes it a nutritiously beneficial as well as delicious ingredient in any keto diet.
