Ingredients

To make garlic roasted green beans and mushrooms, you’ll need:

Green Beans – 1 pound, trimmed
Mushrooms – 8 ounces, halved or sliced (button or cremini work well)
Garlic – 4 cloves, minced
Olive Oil – 3 tablespoons
Salt – ½ teaspoon
Black Pepper – ½ teaspoon
Lemon Juice – 1 tablespoon (optional, for added freshness)
Parmesan Cheese – 2 tablespoons, grated (optional, for garnish)

Step-by-Step Instructions

1. Preheat Your Oven

Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper or a silicone mat for easy clean up.

2. Prepare the Vegetables

In a large mixing bowl, combine the green beans, mushrooms, minced garlic, olive oil, salt, and black pepper. Toss well to coat the vegetables evenly.

3. Arrange on Baking Sheet

Spread the seasoned vegetables in a single layer on the prepared baking sheet. Ensure there is enough space between the pieces for even roasting.

4. Roast the Vegetables

Place the baking sheet in the preheated oven and roast for 20-25 minutes, or until the green beans are tender and slightly crispy, and the mushrooms are golden brown. Toss the vegetables halfway through cooking for even roasting.

5. Add Finishing Touches

Remove the vegetables from the oven and drizzle with lemon juice for added brightness. If desired, sprinkle with grated Parmesan cheese for extra flavour.

6. Serve and Enjoy

Transfer the roasted green beans and mushrooms to a serving dish. Serve warm as a side dish with your favourite main course.

Tips for Success

Trim Green Beans Properly: Remove the tough ends of the green beans for a better texture.
Use Fresh Ingredients: Fresh green beans and mushrooms provide the best flavour and texture.
Don’t Overcrowd the Pan: Spread the vegetables out to allow them to roast evenly and get crispy.

Frequently Asked Questions

How do I get crispy roasted green beans?

Spread the vegetables out in a single layer with space between the pieces. An overcrowded pan makes them steam instead of roast and crisp.

How long do the vegetables take to roast?

Roast at 400°F (200°C) for 20 to 25 minutes, tossing halfway through. They are ready when the green beans are tender and slightly crispy and the mushrooms are golden brown.

Which mushrooms should I use?

Button or cremini mushrooms work well, either halved or sliced. Fresh mushrooms and fresh green beans give the best flavour and texture.
