Ingredients
- 1 pound fresh green beans, trimmed
- 8 ounces cremini mushrooms, sliced
- 3 tablespoons unsalted butter
- 4 cloves garlic, minced
- 1 tablespoon olive oil
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon red pepper flakes (optional)
- 2 tablespoons fresh parsley, chopped
- 1 tablespoon lemon juice
Step-by-Step Instructions
Step 1: Prepare the vegetables by washing and trimming the green beans. Slice the mushrooms into even pieces to ensure they cook uniformly.
Step 2: Bring a large pot of salted water to boil. Blanch the green beans for 3-4 minutes until bright green and slightly tender. Immediately transfer to an ice bath to stop the cooking process and preserve their vibrant color.
Step 3: Heat a large skillet over medium-high heat. Add olive oil and 1 tablespoon of butter. When the butter melts, add the sliced mushrooms and cook for 5-6 minutes until they release their moisture and turn golden brown.
Step 4: Add the remaining butter to the skillet along with the minced garlic. Cook for 1 minute until fragrant, being careful not to burn the garlic.
Step 5: Add the blanched green beans to the skillet along with salt, pepper, and red pepper flakes if using. Toss everything together and cook for 3-4 minutes until the green beans are heated through and coated in the garlic butter sauce.
Step 6: Remove from heat and stir in fresh parsley and lemon juice. Taste and adjust seasoning if needed. Serve immediately while hot.
Expert Tips for Perfect Results
Blanching is Key: Don’t skip the blanching step! It ensures your green beans cook evenly and maintain their beautiful green color. The quick boil followed by an ice bath locks in freshness and creates the perfect texture.
Mushroom Technique: Cook mushrooms in a single layer without overcrowding the pan. This allows them to brown properly rather than steam. If your skillet is small, cook mushrooms in batches.
Garlic Timing: Add garlic towards the end of cooking to prevent it from burning and becoming bitter. The gentle heat will release its flavor without compromising taste.
This garlic butter vegetable side pairs beautifully with main dishes like garlic parmesan chicken and potatoes or slow cooker garlic butter chicken.
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 adjust cooking time accordingly.
What type of mushrooms work best? Cremini mushrooms provide excellent flavor, but you can also use white button mushrooms or sliced portobellos. For a more elegant presentation, try using air fryer garlic green beans as a variation.
How do I store leftovers? Store in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet to maintain texture.
Can I make this ahead of time? You can blanch the green beans and slice mushrooms ahead, but cook everything fresh for best results. The dish comes together quickly once prepped.
