What You’ll Need
Gather these items for your oven-roasted green beans:
- 1 pound green beans, trimmed
- 2 Tbsp olive oil
- 2 large cloves garlic, minced
- Salt + pepper, to taste
- 1/2 cup Parmesan, freshly grated (I recommend Parmigiano-Reggiano for the best flavor)
- 1/2 a lemon, juice
- 1-2 Tbsp fresh parsley, chopped (to garnish)
Feel free to swap out the green beans for asparagus or broccoli if that’s what you have on hand. Just keep an eye on the cooking time!
Directions to Follow
- Preheat your oven to 400°F (200°C).
- Line a large baking sheet with parchment paper for easy cleanup.
- Spread the trimmed green beans onto the baking sheet.
- Drizzle the olive oil over the beans, and toss in the minced garlic, salt, and pepper until everything is well coated. Make sure they are evenly spread out.
- Sprinkle the grated Parmesan over the green beans, ensuring an even layer covers them.
- Roast in the oven for about 20 minutes or until the beans are lightly browned, and the cheese is melty and slightly crispy. The beans should be fork-tender but still have a nice crunch.
- Once done, remove from the oven and drizzle with freshly squeezed lemon juice and garnish with chopped parsley. Adjust seasoning with more salt and pepper if desired. Serve hot!
How to Serve Oven-Roasted Green Beans
These oven-roasted green beans are versatile and can be paired with a variety of main dishes. Serve them alongside grilled chicken, fish, or a hearty pasta dish. For a complete dinner, consider pairing them with a quinoa salad or a side of garlic mashed potatoes. Arrange them in a beautiful serving dish and watch them steal the spotlight!
Storage and Reheating Tips
Leftovers can easily be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply pop them back in the oven at 350°F (175°C) for about 10 minutes to warm through and regain some crispiness. Although freezing isn’t recommended for this dish due to the texture of the green beans, they can be prepped ahead of time and then roasted right before serving.
Pro Chef Tips
- For an even deeper flavor, try roasting the green beans with a sprinkle of red pepper flakes or smoked paprika.
- Make sure your oven is fully preheated before roasting to ensure even cooking.
- Don’t overcrowd the baking sheet—give the green beans space to roast rather than steam.
Creative Twists
Feel free to experiment with this recipe! You could add some zest by incorporating sliced almonds or walnuts for a crunchy texture. If you want a more Mediterranean flair, consider tossing in some cherry tomatoes or olives before roasting. Alternatively, swap out the parsley for fresh basil or mint for a completely different flavor profile.
