Ingredients
- 1 pound fresh green beans, trimmed

- 3 tablespoons butter
- 4 cloves garlic, minced
- 2 tablespoons olive oil
- 1 teaspoon soy sauce (or tamari)
- ½ teaspoon black pepper
- ¼ teaspoon salt
- 2 tablespoons fresh parsley, chopped
- 1 tablespoon lemon juice
Step-by-Step Instructions
Step 1: Blanch the green beans in boiling water for 3-4 minutes until bright green and slightly tender. Drain and immediately transfer to an ice water bath to stop the cooking process.
Step 2: Heat olive oil in a large skillet over medium-high heat. Add sliced mushrooms and cook for 5-6 minutes until golden brown and tender.
Step 3: Reduce heat to medium and add butter to the skillet. Once melted, add minced garlic and cook for 1 minute until fragrant.
Step 4: Add the blanched green beans to the skillet along with soy sauce, salt, and pepper. Toss everything together and cook for 2-3 minutes until the green beans are heated through.
Step 5: Remove from heat and stir in fresh parsley and lemon juice. Serve immediately while hot.
Expert Tips
For the best texture, don’t skip the blanching step – it ensures your green beans stay crisp-tender rather than becoming mushy. If you’re looking for even more flavor, try adding a pinch of red pepper flakes or some grated Parmesan cheese at the end.
This dish pairs beautifully with garlic butter chicken pasta or restaurant-style herb chicken. The savory flavors complement each other perfectly.
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet to maintain the best texture.
