Ingredients
- 1 pound fresh green beans, trimmed
- 8 ounces cremini mushrooms, sliced
- 3 tablespoons butter
- 4 cloves garlic, minced
- 1 tablespoon olive oil
- 1/4 teaspoon red pepper flakes (optional)
- Salt and freshly ground black pepper to taste
- 2 tablespoons fresh parsley, chopped
- 1 tablespoon lemon juice
Step-by-Step Instructions
Step 1: Bring a large pot of salted water to boil. Add green beans and blanch for 2-3 minutes until bright green and slightly tender. Immediately transfer to an ice bath to stop cooking, then drain thoroughly.
Step 2: Heat olive oil in a large skillet over medium-high heat. Add mushrooms and sauté for 4-5 minutes until golden brown and tender. Season with salt and pepper.
Step 3: Reduce heat to medium and add butter to the skillet. Once melted, add minced garlic and red pepper flakes (if using). Sauté for 1 minute until fragrant.
Step 4: Add the blanched green beans to the skillet and toss to coat in the garlic butter sauce. Cook for 2-3 minutes until beans are heated through and tender-crisp.
Step 5: Remove from heat and stir in lemon juice and fresh parsley. Adjust seasoning with additional salt and pepper if needed. Serve immediately.
Expert Tips
Blanching is Key: Don’t skip the blanching step! It ensures your green beans stay vibrant green and achieve the perfect tender-crisp texture without becoming mushy.
Mushroom Selection: Cremini mushrooms work beautifully, but you can also use button mushrooms or shiitake for deeper flavor. For an extra umami boost, try adding a splash of soy sauce instead of salt.
Make it a Meal: Turn this side dish into a complete meal by adding cooked chicken or serving it alongside garlic butter chicken pasta for a comforting dinner.
Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet to maintain texture.
Frequently Asked Questions
Can I use frozen green beans? Yes, but thaw them completely and pat dry before cooking. Frozen beans may release more water, so you might need to cook them a bit longer to evaporate excess moisture.
What main dishes pair well with this side? These garlic butter green beans complement almost any protein. They’re perfect with herb-roasted chicken or as part of a vegetable medley with honey glazed carrots.
Can I make this ahead of time? You can prep the vegetables ahead, but for best texture, cook just before serving. The dish comes together so quickly that last-minute preparation is easy.
