Double the Delight: This Genius Hack Transforms Green Bean Casserole!

The quintessential green bean casserole, a staple at many Thanksgiving dinners, traditionally includes ingredients such as canned green beans, condensed mushroom soup, black pepper, milk, soy sauce, and crispy fried onions. This dish was invented by Dorcas Reilly, an employee at Campbell’s Soup Company, in 1955. It gained fame quickly after the recipe was printed on the label of Campbell’s Cream of Mushroom soup cans.

Interestingly, I don’t recall ever having green bean casserole at our family Thanksgiving feasts. It might have been due to my mother’s preference for green beans cooked with bacon.

This situation turned out to be advantageous, as nobody in my family was attached to the traditional recipe, which allowed me the freedom to experiment with my own version of green bean casserole. Through this experimentation, I discovered an ingredient that can significantly enhance any green bean casserole recipe: miso.

The Benefits of Adding Miso to Green Bean Casserole

Miso, a fermented soybean paste, might seem like an unconventional choice for a casserole. However, its fermentation process creates a rich, savory taste that enhances dishes with a balanced blend of salty and sweet flavors. This complexity and fullness of umami closely align with the rationale behind Dorcas Reilly’s original inclusion of soy sauce in her recipe, as both ingredients intensify flavors beyond what salt alone can achieve.

For making green bean casserole, I prefer using white (or shiro) miso. It’s gentler and subtler than other types and complements vegetables like green beans beautifully.

Nowadays, miso is readily available in most supermarkets, usually found in the international foods aisle or near the produce or tofu sections in the refrigerated area.

Incorporating Miso into Your Green Bean Casserole

You can start with a traditional green bean casserole recipe or try a new one, ensuring that the other ingredients are relatively mild in flavor. Ingredients with strong flavors, such as sun-dried tomatoes or olives, might not mix well with miso due to conflicting tastes. For most other recipes, feel free to add miso—it’s versatile!

I suggest mixing in one tablespoon of white miso directly into the sauce. Since it’s a paste, you’ll need to blend it thoroughly to dissolve it completely. After mixing, taste the sauce and add more miso, a teaspoon at a time, to achieve the desired level of umami, then continue with the recipe as usual.

Additional Advice for Using Miso

When you buy miso, you’ll likely purchase more than needed for a single casserole. Keep any leftovers refrigerated in their original container, tightly sealed. Although miso can last indefinitely if stored properly, I aim to use it within a year for best quality. 

Miso is also a great addition to many other dishes aside from the classic miso soup:

• Enhance salad dressings and marinades with it for deeper flavor
• Add it to soups like mushroom, French onion, and lentil for extra umami
• Incorporate it into your favorite stir-fry recipes
• Mix with rice wine vinegar and sesame oil to create a glaze for fish, chicken, or pork
• Try making Miso-Glazed Salmon, a personal favorite
