Cube the sweet potatoes evenly so they roast at the same rate, and aim for just-tender during the first roast to prevent mushiness after the final bake. If you prefer more heat, add 1/4 to 1/2 teaspoon chipotle powder or swap in pepper jack cheese. For a crispier top, broil the casserole for 1 to 2 minutes at the end, watching closely. This dish can be assembled up to a day ahead; refrigerate covered and add 10 minutes to the bake time. Serve with avocado, sour cream, or a quick slaw for brightness, and use any melty cheese you like, such as cheddar or Oaxaca. To make it vegan, omit cheese or use a plant-based alternative and add 2 tablespoons nutritional yeast to the filling for extra savoriness.
