This green bean and mushroom recipe is a quick and healthy side dish. You only need one pan to saute the vegetables, then steam them until tender.

Recipe Science

  • Steaming green beans uses less water and preserves nutrients better than boiling.
  • Brown mushrooms, with their longer aging, give them a robust flavor and thicker skin, perfect for sautéing.
  • Add fermented soy sauce to the mushrooms for a strong umami flavor. The salt enhances the overall dish’s flavor.

Why It Works

This mushrooms and green bean recipe is a crowd-pleaser no matter the occasion, from a quick weeknight dinner to holiday celebrations. This lighter option is my go-to when I’m not making a green bean casserole to share. Plus, it’s ready in under 30 minutes!

Typically I blanch the beans in boiling water, but to cut down on clean-up, I use a one-pot steaming method instead. The mushrooms are sauteed in the skillet, and the beans are added and cooked in the same pan. You’ll be surprised how quickly the beans tenderize! This gives you ample time and space to make stovetop chicken or mashed potatoes.

Ingredients You’ll Need

Ingredients need to make this green beans and mushrooms recipe.
  • Green Beans: Fresh green beans or slender haricot verts can be used. Haricot verts are picked earlier, so they will have thinner skin, and you can typically skip the trimming.
  • Oil: Fruity olive oil is used to saute the mushrooms and alliums.
  • Mushrooms: For a stronger umami taste, use brown mushrooms like cremini or Baby Bella. They have been aged longer than white button mushrooms, giving them a brown hue, thicker skin for sauteeing, and a robust flavor.
  • Alliums: Minced garlic and diced yellow onions add an earthy flavor and natural sweetness to the dish.
  • Water: All you need is ¼ cup of water to create steam in the vessel to cook the green beans.
  • Seasoning: Soy sauce, salt, and pepper enhances the savory taste of the vegetables.
  • Butter: Melted over the vegetables right before serving to add richness to the dish.

Ingredient Substitutions

Now that you know how to cook green beans and mushrooms, it’s easy to switch up! Try these tasty options:

  • Beans: Frozen or canned green beans can be used. They do not need to be steamed; they are just reheated with the seasonings.
  • Mushrooms: Other types of mushrooms, such as portobello, dried porcini, trumpet, or king mushrooms, can be used.
  • Make it Gluten-Free: Use gluten-free tamari or coconut aminos. The latter has a sweeter taste.
  • Make it Dairy-Free: Skip the butter or add margarine or more olive oil to light coat the vegetables.
  • Add Heat: Sprinkle on dried red chili flakes, stir in Sriracha, chili oil, or hot sauce.

How to Make Green Beans and Mushrooms

Green beans on a wooden cutting board with the stems trimmed off.

Step 1: Prepare the Green Beans

Wash the green beans well with cold water then trim off the tough stem end. If the beans are very long, cut them in half.

Step 2: Cook the Mushrooms 

Gently rinse any dirt or debris from the surface of the mushrooms, then dry well with a towel. Slice into 1/2-inch thick pieces. They will shrink significantly after cooking.

Cook in a large skillet with olive oil to lightly brown the surface. I season with salt to dry out the moisture for quicker cooking and flavoring of the fungi.

Tips for Perfect Execution: Don’t overcook the mushrooms! You want them to begin to release their moisture and get color on the surface.

Step 3: Cook the Aromatics

Once the mushrooms tenderize after a few minutes, briefly saute the minced garlic and chopped onions.

Cooking will lightly caramelize the allium’s natural sugars. The raw and sulfurous taste of these two ingredients mellows out, adding earthiness to the dish.

Step 4: Cook the Green Beans 

Add the green beans, water, soy sauce, salt, and pepper to the pan with the mushroom mixture. Stir, then cover and cook over medium-high heat. The steam from the water and the moisture released from the raw legumes cook them in less than 5 minutes!

Pro Tip: Instead of blanching the green beans in a separate pot of boiling salted water and shocking them with ice water, try steaming them. I use the same method for sauteed green beans, which dramatically cuts down on dishes and cooking time.

Step 5: Add the Butter

I like to add butter before serving to bump up the flavor. It coats the beans, adding richness.

Frequently Asked Questions

Can I use frozen or canned green beans?

Yes! Add them directly to the pan after cooking the mushrooms and onions. Stir until the beans are hot, and add the seasoning and butter. You’ll need 4 cups for the recipe.

Do you have to blanch green beans before sauteing?

No! The green beans can be cooked in hot fat and then added to the pan with water, stock, or broth. Cover and steam until the vegetables are crisp-tender. It takes 5 minutes or less!

What can I add to green beans for taste?

Add garlic powder or onion powder for roasted allium notes to bump up the flavor of the crisp and slightly sweet legume. Fresh or dried herbs like thyme, oregano, or basil. Crushed red chili flakes for heat. Soy sauce to intensify the umami flavor.

How does soy sauce boost the flavor of vegetables?

A small amount of fermented soy sauce intensifies the mushrooms’ umami flavor. You don’t need a lot—just a teaspoon adds a stronger savory and meaty taste. The salt lightly coats the beans, seasoning the entire dish.
