First step is blanching the green beans. Start a pot of water to boil. While it is heating up, get a medium sized bowl with a few handfuls of ice and fill it halfway up with water. Once the water is boiling, add the green beans and cook until the beans are dark green in color, about two minutes. When the beans are dark green, pour off the boiling water and then place the green beans in the ice water bath. Once the beans are cool to the touch, dump out the water, dry off the beans and set aside.
Heat a large heavy skillet over medium-low heat. Add your olive oil and butter and stir until the butter is melted. Add the garlic and stir until the garlic is just beginning to brown, it should take about one minute. Add the red pepper flakes and stir for another thirty seconds. Add the green beans and continue to cook until the beans are heated through and coated with the butter, another few minutes. Plate the beans and toss with the lemon juice. Salt and pepper to taste.
