Tip

Since this recipe relies on leftovers, you may have more or less ingredients than listed. Feel free to adjust based on what you have on hand. For example, if you have a lot of leftover mashed potatoes, add an extra layer to the bottom of the dish.

Step 1

Preheat the oven to 400°F. Grease a casserole dish and set aside.

In a large skillet, warm about 1 tablespoon oil or butter. Add the onions and cook for 5 to 7 minutes, or until tender. Add the garlic and cook for 30 seconds.
