I usually take a minute to explain why each recipe on this site fall into specific dietary categories, so my readers have a better idea of what each diet is about and how to modify for their own needs. Keto is a diet focused on keeping the body in a state of ketosis. In this state, the body starts to burn fat for fuel. You do this by consuming under a certain number of carbs per day, typically 20G or less. Green beans and mushrooms both have very few carbs. Instead of milk or cream, the sauce is made with cashews and almond milk. The traditional breading on the fried onions is swapped for almond flour, one of the best flours to use on the keto diet.
Both Whole 30 and Paleo diets focus on eating whole foods that are minimally processed, avoiding any inflammatory ingredients, like gluten, grains, dairy, and legumes. This dish contains none of those ingredients, only real fresh ingredients—nothing canned in this dish. Soy sauce is traditionally found in green bean casseroles, so we swap that out for coconut aminos, which is a soy and gluten-free “Soy Sauce,” both Whole 30 and Paleo approved.
