Ingredients
- 1 lb fresh or frozen green beans (trimmed)
- 1 Tbsp olive oil
- 1 Tbsp unsalted butter
- 8 oz fresh button mushrooms, cleaned and sliced
- 1 small onion, diced (about 4 Tbsp)
- 1 Tbsp soy sauce
- 1 tsp sesame oil
- Salt and pepper, to taste
Instructions
- Prepare the Green Beans:
If using frozen green beans, follow the stovetop cooking instructions on the package. For fresh green beans, trim both ends of the beans. Alternatively, you can purchase pre-trimmed green beans to save time. Fill a medium pot with water, about 2/3 full, and bring it to a rapid boil. Add the trimmed beans and cook for 6-7 minutes until crisp-tender. Drain the beans and immediately rinse them under cold water to stop the cooking process. Set them aside. - Sauté the Vegetables:
Heat a large skillet over medium-high heat. Add the olive oil and butter. Once the butter is melted, add the sliced mushrooms and diced onions. Sauté for 3-5 minutes, until the mushrooms are tender and the onions are softened. - Combine and Season:
Add the cooked green beans to the skillet with the mushrooms and onions. Drizzle with soy sauce and sesame oil. Sprinkle with salt and pepper to taste. Stir everything together and sauté for another minute. Once everything is well combined and heated through, remove from heat and serve.
Tips
- Prevent Overcooking the Green Beans: To maintain the beans’ vibrant color and crisp texture, be sure to rinse them with cold water immediately after boiling.
- Flavor Boost: If you prefer a richer flavor, add a sprinkle of garlic powder or crushed red pepper flakes for a hint of spice.
- Use Fresh Beans: Fresh green beans will yield a slightly firmer texture compared to frozen beans, but both work well in this dish.
Variations and Substitutions
- Add Protein: For a more filling dish, you can add grilled chicken or shrimp to the skillet when combining with the green beans.
- Swap the Mushrooms: If button mushrooms aren’t your favorite, try using cremini, shiitake, or portobello mushrooms for a deeper flavor.
- Make it Vegan: Substitute the butter with a plant-based butter to make this dish vegan-friendly.
