Green Bean Casserole Without Mushroom Soup

No Mushroom Green Bean Casserole

This easy homemade green bean casserole is like the upgraded, healthier version of the classic Thanksgiving side dish. No canned mushroom soup here – we’re talking homemade creamy goodness. Tender green beans (there’s no need to blanch first!) get dressed in a velvety sauce made with caramelized mushrooms, garlic, and Greek yogurt! Plus, it’s incredibly easy, which is a Godsend, especially during the holidays when you’re juggling multiple recipes and need something fuss-free. And if you’re wanting to try a unique, Asian-flavored version, you’re going to love this miso green bean casserole.

Ingredients

I am highlighting just the ones that need further explanation. The complete list is in the recipe card below.

Green beans – I like to use French-cut frozen green beans for ease and convenience but you can use also use fresh green beans, if preferred. I don’t recommend canned beans for this recipe. Fresh mushrooms – white, cremini, or baby bella will all work. Butter and flour – needed to make the roux. Butter also adds flavor and richness. You can use all purpose flour or gluten free flour. Vegetable broth – feel free to use chicken broth if you prefer. Milk – I use whole milk but you can used 2% milk or your favorite non-dairy milk, like unsweetened almond milk, oat milk, or even coconut milk. Here’s the best milk for baby 1 year and older. Greek yogurt – for extra creaminess and a nutritional boost. You can also opt for sour cream or cream cheese instead. Parmesan – use freshly grated rather than a canned one for best flavor. You can even add some cheddar cheese. French fried onions – so convenient and adds a ton of texture and flavor. Alternatively, you have the option to prepare them at home or use panko breadcrumbs for a different twist.
