Ingredients You’ll Need
You only need a handful of simple ingredients to make this dish shine:
- Fresh green beans, trimmed
- Mushrooms (button or cremini), sliced

- Salt
- Black pepper

How to Make Garlic Butter Sautéed Green Beans and Mushrooms
Step 1: Prep the Vegetables
Wash and trim the green beans, snapping off the ends. Slice the mushrooms evenly so they cook at the same rate.
Step 2: Sauté the Mushrooms
Heat a large skillet over medium heat. Add butter (and a little olive oil if desired). Once melted, add the mushrooms and cook until they release their moisture and turn golden brown.
Step 3: Add Garlic
Stir in the minced garlic and cook for about 30 seconds, just until fragrant. Be careful not to let it burn.
Step 4: Cook the Green Beans
Add the green beans to the skillet. Sauté for several minutes, stirring occasionally, until they are tender-crisp and well coated in the garlic butter.
Step 5: Season and Serve
Season with salt and black pepper to taste. Serve warm straight from the skillet.

Tips & Variations
- Extra brightness: Finish with a squeeze of fresh lemon juice.
- Spice it up: Add a pinch of red pepper flakes for gentle heat.
- Herbs: Fresh parsley or thyme adds a lovely aroma.
- Dairy-free option: Swap butter for plant-based butter or olive oil.
- More veggies: Onions or bell peppers pair beautifully here.
Serving Ideas & Storage
This dish pairs wonderfully with roasted chicken, grilled steak, baked fish, or hearty grain bowls. It also works as a light vegetarian main when served over rice or quinoa.
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet to maintain texture.

Instructions
1. Prep the veggies: Trim green beans and slice mushrooms evenly.

3. Add garlic: Stir in minced garlic and cook 30–45 seconds until fragrant (don’t let it brown).

Notes
For extra-tender beans, blanch green beans 2–3 minutes in boiling water, then drain before sautéing.

Storage: refrigerate in an airtight container up to 3 days; reheat gently in a skillet.
Best texture tip: don’t overcrowd the pan—use a wide skillet for better browning.
