How to Make Green Beans with Mushrooms Recipe
Step 1: Prep the Green Beans
Start with either fresh or frozen green beans for this Green Beans with Mushrooms Recipe. If you’re using fresh beans, trim the ends, or reach for pre-trimmed ones to save a little time. Blanch the beans by boiling them in a generous pot of water for about six to seven minutes until they’re bright green and just tender. Once they’re done, drain and rinse them under cold water immediately—this locks in the vivid color and stops the cooking in its tracks. Set them aside while you work on the mushrooms and onions.
Step 2: Sauté Mushrooms and Onions
This is where the flavor magic starts happening. Heat a large skillet over medium-high and add both olive oil and butter. The combination gives a lovely, layered flavor to the Green Beans with Mushrooms Recipe. Toss in the sliced mushrooms and finely diced onion. Sauté for about three to five minutes, stirring now and then, until the mushrooms are golden and the onions have softened and turned aromatic. The savory aroma alone will make you hungry!
Step 3: Combine and Season
Add your blanched (or defrosted and cooked) green beans straight into the pan. Drizzle on the soy sauce for that irresistible salty–umami note, then add the sesame oil for depth. Give everything a good toss so the beans and mushrooms are coated. Taste, then sprinkle in salt and freshly cracked pepper as needed. Let everything sauté together for just a minute more to marry the flavors, stirring gently so the beans stay whole.
Step 4: Serve and Enjoy
Transfer the finished Green Beans with Mushrooms Recipe to a serving dish while still warm. They’re perfect as a hearty side dish, or even as a lighter main if you’re in the mood for veggies. No one will be able to resist the glossy sheen and richly layered flavors!
How to Serve Green Beans with Mushrooms Recipe

Garnishes
For a little extra flair and flavor, try sprinkling freshly chopped parsley or snipped chives right before serving. If you love a bit of texture, toasted sliced almonds or a dusting of crunchy fried onions is fantastic on top—think of it as a modern nod to classic green bean casseroles.
Side Dishes
This dish pairs beautifully with almost any main. Serve it next to roast chicken, seared salmon, or baked tofu for a satisfying combination. It’s a natural fit on a Thanksgiving table alongside stuffing and mashed potatoes, but also feels right at home as a weeknight veggie boost.
Creative Ways to Present
If you’re serving guests, consider arranging the green beans and mushrooms on a long platter for an elegant look, with some colorful microgreens for contrast. Or, toss the mixture into a warm grain bowl with quinoa or farro for a filling vegetarian lunch. You can even pile them onto toasted sourdough with a poached egg for a brunch-worthy twist!
Make Ahead and Storage
Storing Leftovers
Leftover Green Beans with Mushrooms Recipe keeps very well in the fridge. Once cooled, transfer them to an airtight container and store for up to 3 days. The flavors continue to meld, making the leftovers even more delicious.
Freezing
While fresh is best, you can freeze portions of this dish if needed. Let it cool completely, then stash in freezer-safe containers or bags for up to a month. When thawed, the texture of the beans and mushrooms may soften slightly, but the flavor stays terrific.
Reheating
To reheat, simply warm your Green Beans with Mushrooms Recipe in a skillet over medium heat with a splash of water, or microwave on medium power until heated through. Be careful not to overcook, as you want the beans to stay tender instead of mushy.
FAQs
Can I use other types of mushrooms?
Absolutely! While button mushrooms are classic in this Green Beans with Mushrooms Recipe, cremini or baby bella mushrooms bring a meatier flavor and work just as well.
Is it possible to make this fully vegan?
Yes, just skip the butter and use more olive oil, or a dairy-free butter substitute. The dish will still have a deliciously rich taste thanks to the umami from soy sauce and sesame oil.
Can I prepare this dish in advance for a gathering?
You sure can. Prepare the dish up to a day ahead and keep it covered in the fridge. Just reheat gently on the stove before serving, and add a splash more soy sauce or olive oil if you like.
What’s the best way to keep the green beans vibrant and crisp?
Blanch the green beans just until they’re crisp-tender and plunge them in cold water right away—that quick chill locks in both color and texture for your Green Beans with Mushrooms Recipe.
Can I add extra seasonings or spices?
Definitely! Red pepper flakes bring a little heat, or a clove of garlic can be sautéed with the onions for extra depth. The recipe is flexible, so make it your own.
