This Green Bean Casserole is so creamy and crunchy (thanks to the homemade French Fried Onions) and better than the original! You’ll never guess it’s gluten-free, grain-free, dairy-free, and paleo! (Even though recipe says "canned goods; cream of mushroom soup" the soup is actually HOME-MADE & DAIRY-FREE.
The Best Green Bean Casserole! You make your own cream of mushroom soup with portobello mushrooms and add sweet yellow onions and garlic. Then you stir in perfect fresh green beans and top it with crispy french fried onions!
