Move aside fresh vegetables, frozen vegetables are a fantastic, low cost, long lasting simple side dish. They're fresher (because they're frozen at peak freshness vs picked early for transport), and can be used in many ways.
I often dump frozen vegetables into a sauce or dish I'm making, but you can't just add vegetables to any dish. They really are best when added to a sauce or liquid. The water in frozen vegetables wouldn't help the texture of crispy food.
That's why frozen roasted green beans (and other roasted frozen veggies) are so helpful. They have enough dry heat to melt and evaporate the ice, then crisp up. This is a great, quick cooking method for busy weeknight dinners!
You can make these frozen roasted green beans on the stovetop or Air Fryer. I find green beans and similar vegetables (like ones without florets) cook up really well in an Air Fryer because the small parts don't get dried and burnt.
I've worked on a few frozen cooked vegetable recipes lately (scroll down for them), and keep the seasonings simple. When you're cooking for one, batch cooking foods is a helpful time saving technique.
What that looks like is making extra servings of frozen roasted green beans and then add more seasonings as you're adding them to different dishes. That way the flavors go well together and are delicious.
This frozen roasted green beans recipe is my favorite tasty side dish because it takes minimal prep time, you can batch roast them while you're already cooking, so you don't have to spend a weekend afternoon meal prepping!
Scroll down to the frozen roasted green beans recipe card for the amounts of each ingredient, but here's a quick visual + description of what's in this recipe.
- Frozen green beans: You can use fresh green beans or another frozen vegetable for this easy side dish of frozen roasted green beans. Cooking times may vary though, so keep an eye on them.
- Olive oil
- Kosher Salt: I use kosher salt, because that's what I keep on hand, and like the larger flakes, but you can use sea salt or other salt that you have. Adjust the amount you add if using a different type since they are all different sizes.
- Garlic powder: It's my favorite way to get a touch of garlic flavor without mincing or burning garlic. If using fresh garlic cloves, you may want to add them in the last 10 or so minutes of cooking, so they don't burn.
- Black Pepper
