Ingredients

Ingredients on a counter top.
  • Green beans - Fresh or frozen green beans work in this recipe. If you have canned green beans on hand, skip the step of boiling and continue with the recipe as written. Canned green beans will not turn out crisp-tender like fresh or frozen beans.
  • Onions and garlic - Add flavor to your green beans. I don't recommend omitting either ingredient because they add a significant amount of flavor to the dish.
  • Salt and pepper - Enhances the flavor of the green beans. You could also try adding your favorite seasoning blend, like a pinch of cajun seasoning or everyday seasoning for more flavor.

How to make green beans and onions

Making green beans and onions.
  1. Trim the ends and slice green beans in half.
  2. Bring water to a boil in your sauté pan and cook green beans for 5 minutes, then drain and set aside.
  3. Return pan to stovetop, melt butter, and sauté onions and garlic.
  4. Add green beans and seasoning, stir to combine, and cook for an additional minute.

Tips and tricks

Fresh green beans - I highly recommend using fresh green beans for this recipe. The extra flavor from using fresh produce can't be beat. If you can't find any fresh green beans, I recommend using frozen green beans instead. They'll thaw while boiling, so they don't even need to be thawed beforehand.

Trimming green beans - First, turn all of your green beans with the stems pointing in the same direction. Gather them in a small bundle and trim off the stem ends, about ¼ to ½ inch in. There is no need to trim the opposite "curly" end of the green bean - it can be eaten as is.

Frequently asked questions

Can I use canned green beans?

While fresh or frozen green beans have the best flavor, canned green beans can work in this recipe. Simply skip step one (boiling), and continue with the recipe as written.

How long do leftover green beans last?

Leftovers will keep for 3 to 4 days in a tightly sealed container in the refrigerator.
