Easy Green Bean Casserole Recipe from Scratch

0 from 0 ratings

Growing up, one of the most common dinnertime meals that my parents used to make was a casserole. You wouldn’t believe how many different types of casseroles I’ve eaten throughout my life. All because of this though, casserole remains to this day one of my favorite types of meals to prepare. They really do make an excellent addition to any type of dinner feast. Today I wanted to share one of my favorite types of this classic meal--the humble green bean casserole. It has a healthy mix of tasty vegetables including the green beans, garlic, mushrooms, and a topping made with sliced onions. In addition, the topping uses almond flour while the casserole sauce uses arrowroot flour, making this recipe completely gluten-free.

Looking for a delicious paleo-friendly take on a classic dish? Look no further than this incredible green bean casserole. Featuring a mixture of healthy veggies, almond flour to keep it gluten-free, and chicken broth, it’s absolutely loaded with flavors while being unbelievably good for you as well.

Healthy Vegetables and Gluten-Free Flour Make A Delicious Paleo Casserole

What makes this casserole recipe so good is the blend of all-natural ingredients. Starting with what makes the recipe gluten-free, you’ll be using almond flour for your topping along with the sliced onions and salt. I love using almond flour in my recipes because it’s so nutrient dense, being high in protein, vitamins, and minerals. It also adds a deliciously sweet taste to recipes it’s added to. The sauce makes perfect use of arrowroot flour as well. Just like almond flour, it’s grain-free making it a perfect paleo ingredient. Not only is this starchy flour perfect for baking with, but it has many great digestive benefits as well.

Green Beans, A Good Source of Antioxidants and Immune Boosting Properties

Green beans are an incredibly versatile vegetable that provide you with a wide range of amazing health benefits. They’ve been shown to boost your immune system and provide protection for your cardiovascular system while also carrying a solid amount of antioxidants. (3) One study in particular even looked at the promising effects of a diet containing both green beans and onions for individuals with diabetes; the results of that study show that this casserole could be a potential meal option for diabetics as well. (4) To round out the casserole sauce, we have some mushrooms, garlic cloves, paleo homemade chicken broth, almond milk, and even some nutmeg to boost the flavor profile of this dish. They all combine to make an unbelievably tasty casserole.
