Frozen green beans- You will need some frozen green beans for this recipe. Make sure to pay attention to the "style" that the green beans are cut, as some may be French cut or skinnier than others. They're fine to use but may require a close eye to make sure that they don't burn or overcook.
Olive oil- This will help to bind the spices to the green beans and give them a crispier texture when cooked.
Seasonings- Keeping the seasonings simple with some salt, pepper, onion powder, and garlic powder keeps this recipe frugal and tasty.

🍴 Recipe Tips
Cooking frozen green beans is easy, but because these greens start off frozen, they do take a little longer than fresh ones would cook. This is because of the excess moisture and chill factor, but you'll notice that by the 15-minute mark they're actually looking good!
In fact, you could be done at that point if they seem heated through, but the extra 15 minutes gives them a little firmer bite for those of us who like a crisper green bean.
You can modify the seasonings to your own liking, but I like this simple and basic combination because it's perfect for pairing with practically anything.
👩🏻🍳 Storage
Leftover green beans can be stored in an airtight container in the fridge for about 3-5 days. Simply reheat and eat when ready.
