Ingredients Needed

Ingredients measured out to make Roasted Green Beans: lemon juice, olive oil, green beans, sea salt, pepper and garlic.

green beans – fresh, crisp green beans are the star here. Look for beans that are bright in color and snap easily when bent. They should be firm, not limp, for the best roasting results.
olive oil – adds a nice richness and helps the green beans roast to perfection. Use a high-quality extra virgin olive oil for the best flavor.
garlic – fresh garlic is a must for that bold, savory flavor. Minced garlic works best, and the aroma as it roasts? Absolutely heavenly!
sea salt and pepper – simple but essential. Seasoning is key to bringing out the natural flavors of the green beans.
lemon juice – adds a bright, zesty finish that balances out the richness of the oil and garlic. Fresh is always best, so grab a lemon and squeeze it right over the roasted beans for a burst of freshness!

Variations

Spicy – Love a little heat? Add a pinch of red pepper flakes or a drizzle of sriracha before roasting for an extra kick.
Cheesy – If you’re a fan of cheesy goodness, sprinkle freshly grated Parmesan or nutritional yeast (to keep things vegan) over the green beans. Add it halfway through roasting so it melts perfectly.
Herby – Toss the beans with fresh or dried herbs like rosemary, thyme, or oregano. It adds such a nice boost of flavor, especially if you love herby dishes.
Balsamic: For a sweet and tangy twist, drizzle some balsamic vinegar or balsamic glaze on top right after roasting.

Brittany’s Tip

Roast at high heat: A hot oven (400°F or higher) is key for perfectly roasted green beans. It helps them cook quickly and develop that golden, caramelized finish without getting mushy. Keep an eye on them so they don’t overcook!

Frequently Asked Questions

Why are my roasted green beans tough?

If your roasted green beans are coming out tough, it might be due to their freshness, older beans can be a bit drier. Try blanching them for a couple of minutes before roasting to soften them up, and roast at 400°F or higher for that perfect tender-crisp texture!

What type of oil is best for oven roasted green beans?

Olive oil is my go-to for roasting veggies, but avocado oil would work well here. Don’t use oils like coconut oil or butter as these have lower smoke points.

Can I freeze roasted green beans?

While I don’t recommend freezing roasted green beans because they can get a bit mushy when thawed, you can freeze them if needed. Store in an airtight container or freezer bag for up to 2 months. When reheating, pop them in the oven to try and get some of that crisp texture back.
