How to cook frozen green beans in the oven

Step 1: Preheat the oven to 450 degrees. High heat is important for getting the right texture when roasting anything that is frozen.

Do you thaw frozen green beans before cooking?

One very important thing to note is that I do not recommend thawing your frozen green beans before cooking them.

I have found the key to the best texture when working with frozen vegetables is to put them straight from the freezer onto the pan, and roast immediately.

When you allow the vegetables to thaw, that is when the mushy texture happens.

Step 2: Once the oven is preheated, take the frozen cut green beans out of the freezer and toss them with olive oil.

Add the salt, garlic powder, onion powder and then toss again to combine.

What spices go well with green beans?

Simple spices work well with just about any vegetables. You cannot go wrong with the basics – salt, pepper, onion powder, garlic powder.

If you want a spicy kick, you could add a pinch of paprika.

Step 3: Place the green beans on a baking sheet and roast at 450 degrees for 15 minutes.

Step 4: Stir the green beans. Sprinkle the parmesan over the top of the green beans and leave it, do not stir again yet.

What kind of parmesan cheese to use

I used the small powdery fresh parmesan that is located in the cheese section.

It looks similar to the kind of parmesan you use for spaghetti.

Either will work, but I do not recommend the long shreds of parmesan for this recipe.

The small pieces work so well to distribute the crispy texture of parmesan edges on the green beans.

Step 5: After 15 minutes, you can stir again. From here, roast the green beans until they are the desired texture, anywhere from 5-15 more minutes depending on your oven and type of sheet pan. Some cook faster than others.

The crispy parmesan bits on the green beans made the flavor incredible!
