FAQs
Can I use fresh green beans instead of frozen?
Yes, you can. However, keep in mind that fresh green beans may require less time to cook than frozen ones.
Do I need to thaw the frozen green beans before roasting them?
No, you don’t have to. In fact, it’s best to roast them directly from frozen, as they will release less moisture and will result in a crispier texture.
Can I freeze the roasted green beans?
Yes, you can freeze them. To do so, let them cool to room temperature, then transfer them to a freezer-safe container or bag. They will keep in the freezer for up to 3 months. To reheat, simply place them on a baking sheet and roast them in a 350°F (177°C) oven for 10-15 minutes, or until heated through.
Can I make the roasted green beans ahead of time?
Yes, you can. Roasted green beans can be stored in an airtight container in the fridge for up to 3 days. To reheat them, simply place them on a baking sheet and roast them in a 350°F (177°C) oven for 5-10 minutes, or until heated through.
What temperature should I roast the green beans at?
A temperature of 400 – 425°F (218°C) is ideal for roasting green beans. This high temperature will help to caramelize the outside of the beans while keeping the inside tender.
How long should I roast the green beans for?
Roasting time will vary depending on the size of the green beans and how crispy you want them to be. Generally, it’s best to roast them for 15-20 minutes. Optionally, you could toss them once or twice during cooking to ensure even roasting – but I don’t find this totally necessary.
What seasonings can I use to flavor the green beans?
Beyond the seasonings listed in the recipe card below, you can use a variety of seasonings to flavor your roasted green beans. For example, you can use garlic powder, onion powder, paprika, or even parmesan cheese. Just be sure to toss the green beans in the seasoning mixture before roasting to evenly coat them.
