Step 1

In a large skillet with a fitted lid, heat the olive oil over medium-high heat. Add the pepper flakes and green beans and toss with tongs or a spoon until the green beans are coated with the olive oil. Cover the pan and reduce the heat to medium. Cook for 7 minutes, stirring every minute or two so the green beans don’t burn. You want them to be blistered and tender, but still have a little “snap.”

Step 2

Remove the lid and add the garlic, stirring to coat the green beans. Add the lemon zest and juice, toss, season with salt and pepper to taste, toss again, and serve immediately.
