About this Green Bean Casserole

For this homemade green bean casserole recipe, I skipped the canned cream of mushroom and made my own homemade garlic soy cream sauce that is absolutely delicious. It’s silky, smooth, savory and tastes amazing. This green bean casserole recipe is the perfect addition to any meal. As an added bonus, you only need one pan too.

The garlic soy cream is lighter than the traditional cream of mushroom sauce. It also carries a lot more flavor. The soy sauce adds a wonderful umami that is hard to resist when combined with the meaty mushrooms. While the garlic cream adds a smooth, creamy texture we all crave from a homemade casserole. Mix everything together, and you’re in for one irresistible holiday side dish. 

I can almost guarantee that this one-pan creamy green bean casserole will be the only way you make green bean casserole in the future. This is one Healthyish remake that you will not want to miss. 

How to Make Green Bean Casserole

When prepping the homemade creamy garlic soy sauce, you’ll want to add the butter, garlic and flour to a 9-inch cast iron skillet. If you do not have a cast iron skillet be sure to use an oven safe pan. Once the butter garlic and flour begin to bubble and are fragrant, slowly add the milk. Once the milk is well combined, add the chicken broth. Finally, you will add the soy sauce. Stir until it’s well combined.

Next, you’ll add the sliced mushrooms and simmer everything over medium low heat. Once the mushrooms begin to soften add the green beans. Season with black pepper and touch of salt. Simmer for another 5 more minutes. Top the dish with the crispy fried onions, cover it with foil and bake for 20 minutes. Remove the foil and bake for another 5 minutes. Serve hot and enjoy.
