• Preheat  oven to 450 degrees.  Line 2 large rimmed baking sheets with foil.  You want the beans to be in a single-layer for roasting.  Otherwise they won’t roast evenly.  Some will steam, some will roast.  No Bueno.

If you prepped the beans the day before

• Just add olive oil and garlic to the zip-loc bag of beans and shake to coat. In a single layer, spread beans onto the baking sheets, squeezing lemon juice over the top, place lemon slices on top.

If preparing Thanksgiving Day
