Gluten-Free Mung Bean Casserole Ingredients
This section explains how to choose the best ingredients for ketogenic mung bean casserole, the role of each ingredient in the recipe, and alternative options. For measurement, please refer to the recipe card below.
For the casserole:
- Avocado oil – I like the neutral taste of avocado oil, but olive oil is fine too.
- onion – I recommend white onions, but yellow onions are also good.
- mushroom – Use white buttons or small bella mushrooms. They need to be sliced, so I purchased pre-sliced ones for convenience.
- green beans – Fresh green beans work best (I like to buy pruned beans to save time), but if you only have frozen ones, you can. I don’t recommend canned green beans because the texture is worse, but if you want a shortcut, feel free to use them, you can skip the step of cooking the beans.
- Creamy Mushroom Soup – Unfortunately, most mushroom soups I see in stores contain starch thickeners and artificial ingredients, so I don’t recommend getting this in a can.I do it myself Tomato Cream Mushroom Soup Instead, it is a combination of mushrooms, onions, garlic, chicken broth, heavy cream and almond milk. Mushroom puree will naturally thicken it, but if you like its taste, you can also melt some cream cheese in it. The soup also provides all the flavor you need, so you don’t need to add any extra salt or pepper to the recipe.
Toppings:
- The wholesome yum Almond powder – This ultra-fine almond flour provides the best flavor and texture. If you want a crisper one, replace half of it with crushed pork skin.
- Dried minced onion – This is the basis of our French fried onion ingredients. No preparations are involved.
- Avocado oil
