Ingredients
- 1 pound fresh green beans, ends trimmed
- 2 tablespoons olive oil
- 3 cloves garlic, minced
- ¼ cup grated Parmesan cheese
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ teaspoon garlic powder (optional)
- 1 tablespoon fresh lemon juice
Step-by-Step Instructions
Step 1: Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.
Step 2: Wash the green beans thoroughly and pat them completely dry with a clean kitchen towel. Trim the ends off the beans.
Step 3: In a large bowl, combine the olive oil, minced garlic, salt, pepper, and garlic powder if using. Add the green beans and toss until they’re evenly coated with the oil mixture.
Step 4: Spread the green beans in a single layer on the prepared baking sheet, making sure they’re not overcrowded. This ensures they roast evenly and become crispy.
Step 5: Roast for 12-15 minutes, tossing halfway through, until the green beans are tender-crisp and slightly browned around the edges.
Step 6: Remove from oven and immediately sprinkle with grated Parmesan cheese and fresh lemon juice. Toss gently to combine while the beans are still hot.
Step 7: Serve immediately while warm and crispy. The Parmesan will melt slightly from the residual heat, creating a delicious coating.
Expert Tips
For the crispiest results, make sure your green beans are completely dry before tossing them with oil. Any excess moisture will steam the beans instead of roasting them. If you love extra garlic flavor, you can add an additional minced clove or sprinkle with garlic powder after roasting.
This versatile side dish pairs beautifully with garlic herb glazed chicken breast or makes a perfect addition to any summer meal. For another delicious vegetable side, try our savory garlic butter green beans and mushrooms recipe.
Don’t overcrowd the baking sheet! If you’re making a larger batch, use two baking sheets to ensure proper air circulation and even roasting. The green beans should have some space between them for optimal crispiness.
Frequently Asked Questions
Can I use frozen green beans? While fresh green beans yield the best texture, you can use frozen. Thaw completely and pat very dry before roasting. They may require a few extra minutes in the oven.
How do I store leftovers? Store in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or toaster oven to maintain crispiness – microwaving will make them soft.
Can I make this dairy-free? Absolutely! Omit the Parmesan cheese or use a dairy-free alternative. The garlic and olive oil base is delicious on its own.
