Why You’ll Love Roasted Frozen Green Beans

Roasting frozen green beans is a remarkably easy and convenient cooking method that delivers a delicious, healthy side dish with minimal preparation. Since they’re roasted straight from the freezer, there’s no need to plan ahead for thawing time, making them a perfect last-minute addition.

Green beans

A serving or two of green beans is an excellent step toward getting your daily vegetables. And a diet high in fruits and veggies is ideal for optimizing your mental health.

Frozen green beans are a fantastic go-to option. They are picked and frozen at the peak of freshness, preserving their vitamins and minerals.

Green beans come with a host of nutrition benefits. They are low in calories but rich in fiber, vitamin C, and vitamin K. Adding this versatile vegetable to your diet is an easy way to boost your intake of essential nutrients.

Extra-virgin olive oil

Renowned as one of the healthiest fats on the planet, extra-virgin olive oil is a cornerstone of the Mediterranean diet. It’s rich in monounsaturated fats (the good fats), which are linked to reducing inflammation. And reducing chronic inflammation can improve your mental health.

How to Make Frozen Roasted Green Beans

Preheat your oven to 450℉. In a medium-sized bowl, stir together the frozen green beans with the olive oil, minced garlic, garlic powder, salt, and pepper.

Tips, Variations, & Substitutions

  • Make sure the green beans have space on the baking sheet. Overcrowding can lead to steaming instead of roasting.
  • Keep an eye on the beans as oven temperatures can vary; start checking for doneness at around 20 minutes.
  • For an added crunch, sprinkle the green beans with almond slivers before roasting.
  • Mix in different herbs like rosemary, thyme, or oregano for a unique twist. Lemon zest also brings a fresh touch to the dish.
  • If you enjoy a little heat, a dash of crushed red pepper flakes will do the trick.
  • If you don’t have extra-virgin olive oil, substitute avocado oil as another healthy fat that works well with high heat.
  • Add grated Parmesan cheese during the last few minutes of roasting for a savory flavor boost.

FAQ about Roasting Frozen Green Beans

Can I cook frozen green beans in the air fryer?

Absolutely, you can cook frozen green beans in the air fryer. Follow the recipe as written, but it may have a shorter cooking time. Begin checking the green beans for doneness after 15-20 minutes. Shake the basket halfway through the cooking time to ensure an even roast.

What type of frozen green beans should I use?

Almost any variety of frozen green beans will work for this roasted green beans recipe. I used cut green beans, but whole green beans would also work. I’m not sure how the French-cut versions would work because they are so small.

How do I store leftovers of roasted frozen green beans, and how long will they keep?

Allow the green beans to cool to room temperature and transfer them to the refrigerator in an airtight container. They should keep well for up to 3 to 4 days. When reheating, you can warm them in the microwave or cook them in the oven or air fryer to help them regain their original texture.
