Oven-Roasted Green Beans with Parmesan, Lemon, and Garlic Recipe
Introduction
Oven-Roasted Green Beans are a quick and flavorful side dish perfect for any meal. With a crispy parmesan topping and a hint of lemon, these green beans deliver a delightful crunch and savory taste in just 30 minutes.

Ingredients
- 1 pound green beans, trimmed
- 2 Tbsp olive oil
- 2 large cloves garlic, minced
- Salt and pepper, to taste
- 1/2 cup parmesan, freshly grated (preferably parmigiano-reggiano)
- 1/2 a lemon, juice
- 1-2 Tbsp fresh parsley, chopped (for garnish)
Instructions
- Step 1: Preheat your oven to 400°F. Line a large baking sheet with parchment paper to prevent sticking.
- Step 2: Spread the trimmed green beans on the baking sheet. Drizzle with olive oil, then add the minced garlic, salt, and pepper. Toss everything together to coat the beans evenly and arrange them in a single layer.
- Step 3: Evenly sprinkle the grated parmesan over the green beans, ensuring they are covered with a good layer of cheese.
- Step 4: Roast in the oven for about 20 minutes until the beans are fork-tender but still crisp, and the cheese is melted and slightly crispy on top.
- Step 5: Remove from the oven and immediately squeeze fresh lemon juice over the beans. Garnish with chopped parsley and adjust seasoning with extra salt and pepper if needed. Serve hot.
Tips & Variations
- To add a spicy kick, sprinkle a pinch of red pepper flakes before roasting.
- Swap parmesan for pecorino romano for a sharper flavor.
- For a nuttier taste, add toasted almonds or pine nuts as a garnish.
- If you prefer softer beans, roast for an additional 5 minutes, watching carefully to avoid burning.
Storage
Store leftover roasted green beans in an airtight container in the refrigerator for up to 3 days. Reheat gently in a preheated oven at 350°F for 5-7 minutes to retain their crispiness, or warm briefly in a microwave.

FAQs
Can I use frozen green beans for this recipe?
Fresh green beans work best for roasting as they retain a firmer texture. If using frozen, thaw and dry them thoroughly before roasting to avoid sogginess.
How do I make this recipe dairy-free?
Simply omit the parmesan or substitute with a dairy-free cheese alternative or nutritional yeast for a cheesy flavor without the dairy.
