Preheat oven to 400 degrees Fahrenheit. Line baking sheet with aluminum foil.
Mix green beans, garlic, olive oil, seasoned salt, and black pepper in a bowl. (In a pinch, you can mix this on the lined baking sheet.)
Pour everything onto the lined baking sheet. Put baking sheet in the oven on the middle rack for 20 minutes (for more crisp green beans) to 25 minutes (softer green beans).
When the green beans are done, take them out of the oven and mix everything well, scraping the baking sheet to get off the stuck browned garlic bits. Serve warm or at room temperature.

Notes
Tips and TricksCooking your protein at the same time as your beans?Put your baking rack on the second from the top level for your green beans. Half way through, take the baking sheet out of the oven and mix the beans so they brown evenly and don’t get burned sitting so close to the top of the oven.Fancy up your green beans!Add sliced onions for a sweeter flavor. Sliced shallots will boost the garlic flavor and give a mild onion flavor. Fresh or dried herbs provide more aroma and extra flavor without added salt.Can I double this recipe?Of course! More green beans on the baking sheet means extra moisture is going to collect on the baking sheet. So, if you don’t have two baking sheets, make sure that you cook the beans for at least 5 minutes longer so the water can evaporate and create more char on the green beans. Another option is to up the heat to 425 degrees Fahrenheit to speed up the evaporation process; stir the beans at the half way point to make sure the garlic doesn’t burn.Can I make this ahead of time?Yes. These green beans taste great at room temperature. You can cook them so they finish up to an hour before you plan to serve it; just make sure you promptly store any leftovers no more than an hour after you serve.You can also cook this up to 2 days in advance. Warm it up in the oven or toaster oven at 350 degrees for 6 to 8 minutes.
