- Parmigiano Reggiano: Finely grated for finishing.
- Kosher salt & black pepper: Freshly ground black pepper and salt to taste.

How to Make Green Beans and Mushrooms
Technique is the key: blanch the beans, shock them, then sauté the mushrooms until deeply browned before finishing with garlic and beans.
- Blanch: Bring a large pot of water to a boil and add the green beans. Cook for two minutes.
- Shock: Drain and rinse the beans in cold water to stop the cooking and preserve color and crispness. Set aside.
- Sauté: Heat oil in a large skillet over HIGH heat. Add the mushroom slices and cook, stirring occasionally, until well browned, about eight minutes. Cook until the mushrooms release their liquid and it evaporates, then let them brown.
- Reduce heat to medium. Add the blanched green beans and minced garlic; cook, stirring frequently, for about two minutes. Taste and season with kosher salt and freshly ground black pepper.
- Transfer to a serving plate and grate Parmigiano Reggiano over the top just before serving.
Can you use Canned or Frozen Green Beans?
Fresh green beans give the best texture and flavor, but frozen green beans are a suitable substitute — add an extra minute or two to the boiling time since they start frozen. Canned green beans generally have a softer texture and added sodium, so they’re less ideal for this preparation.
Why Blanch Before Sautéing?
Blanching followed by shocking tenderizes firm vegetables and ensures green beans stay crisp-tender with vibrant color. You can blanch beans ahead of time and keep them chilled; they’ll quickly reheat when tossed into the hot pan, so avoid overcooking—two minutes in boiling water is usually enough.
What to Serve Them With?
This side pairs well with a wide range of mains, including beef, pork, chicken, seafood, and vegetarian entrees. It adds color, contrast, and a pleasant crunch to richer or more indulgent dishes. Serve it alongside roasted meats, mashed potatoes, or a composed vegetarian plate for balance and texture.
