Whenever mama made this dish, I simply couldn't get enough

Green beans and bacon are a match made in heaven, but they're even more delicious with an additional secret ingredient: the oven. Roasting green beans makes them deliciously caramelized. In the recipe below, they get a bit of extra help with some roasted onions for a low-carb dish with more than its fair share of sweetness.
In this recipe, you'll cook just enough bacon to have the fat you'll need to cook your beans, but consider saving bacon fat every time you cook up a few slices for breakfast. The rich, smoky fat makes chicken or eggs even more delicious.
