With so few ingredients, the quality and flavor of each greatly affects the overall dish, so be sure to choose your vegetables with care. Thin and tender French green beans (haricot verts) are best for this recipe.  Standard button mushrooms or cremini (baby bella) mushrooms work well, but feel free to use your favorite variety of mushroom or a combination.

Ingredients You Need to Make Green Beans and Mushrooms

Green Beans and Mushrooms Ingredient on a white marble board
  • Green Beans: ideally haricot verts (thin, tender green beans)
  • Mushrooms: button mushrooms, cremini mushrooms or your favorite variety
  • Butter: salted or unsalted butter
  • Garlic: fresh garlic cloves
  • Fresh Parsley: optional garnish
  • Kosher Salt and Freshly Ground Black Pepper

Why cook separately and then combine?

The key to perfecting this dish is cooking the vegetables separately before combining them at the end. You’ll sauté mushrooms in butter and garlic and steam the green beans separately before tossing them together in a skillet with a dab of butter and seasoning to finish.

This method ensures that your mushrooms are cooked to perfection and the green beans maintain their vibrant color and gives you more control over how tender you would like them to be. Mushrooms are pretty forgiving, but green beans can be delicate. It’s worth the effort to prepare them carefully so they arrive at the dinner table beautifully slender and intact.

Recipe Options

  • Add sliced or chopped green onions, chives or shallots for added flavor depth.
  • Embellish with minced fresh herbs like rosemary, thyme or tarragon.
  • For an Asian inspired flavor twist: stir in minced fresh ginger with the garlic and a splash of soy sauce. Finish with sesame oil and toasted sesame seeds.

Storage and Reheating Tips

You can store leftover green beans and mushrooms in the refrigerator for 3 to 5 days. To reheat, set a large nonstick skillet over medium-low heat, add the cold vegetables; cook and stir slowly until heated through.


What flavors go well with green beans?

They go well with an endless combination of herbs (e.g., rosemary, thyme), spices (e.g., garlic, ginger) and other vegetables. Here, they’re tossed with sautéed mushrooms and seasoned simply with butter, garlic, salt and pepper.

Do you have to boil green beans before sautéing them?

Quickly boiling (blanching) or steaming green beans before sautéing or roasting helps to cook them evenly and preserve their vibrant green color.

How long do you cook green beans?

The length of cooking time depends on the size of the green beans and the cooking method: steamed 5-7 minutes, boiled 4-5 minutes, roasted 12-15 minutes, grilled 10-12 minutes.

Can you overcook green beans?

Yes! Overcooked green beans are mushy and they fall apart. Keep a close eye on them no matter what cooking method you choose.
