Tips and Tricks
Cut Even Pieces - Keep the sweet potato cubes close to the same size so they roast evenly.Leave Room on the Baking Sheet - Spread the sweet potatoes out so they brown instead of steam. Use two baking sheets if necessary.Keep the Chicken Tender - Avoid overcooking the chicken. It should reach an internal temperature of 165°F.Adjust the Sauce - If the filling becomes too thick, stir in a little additional chicken broth until it reaches your preferred consistency.Use Fresh Spinach - Add the spinach when assembling the bowls so it stays bright green and only wilts slightly from the warm filling.For a Thicker Filling - Let the sauce simmer for another minute or two before returning the chicken to the skillet.
Storing and Reheating
Refrigerator - Store the chicken filling and roasted sweet potatoes in separate airtight containers for up to 3 to 4 days. Keep the spinach separate until serving.Freezer - Freeze the chicken filling for up to 2 to 3 months. The sauce may separate slightly when thawed. Roasted sweet potatoes can also be frozen separately, although their texture may soften.Microwave - Reheat individual portions in a microwave-safe bowl in 30 to 60-second intervals, stirring between intervals, until heated through.Stovetop - Warm the chicken filling in a skillet over medium-low heat, stirring occasionally. Add a splash of chicken broth if the sauce has thickened during storage.Oven - Reheat the sweet potatoes on a baking sheet at 350°F until warmed through. This helps maintain a better texture than microwaving.
