Feeding a crowd can feel overwhelming, especially when it comes to planning portion sizes to ensure everyone gets enough without leaving you with excessive leftovers. If you’re preparing sweet potatoes for 20 people, you might wonder: How many sweet potatoes do I actually need? The answer depends on factors like serving style, preparation method, and whether sweet potatoes will be served as a main dish or a side dish.
For mashed sweet potatoes, plan about 5 pounds (2.3 kg). If you’re serving roasted sweet potatoes, aim for 7.5 pounds (3.4 kg). For whole baked sweet potatoes, count on 20 medium-sized potatoes (6-8 oz each). Peeling and cooking can reduce the final yield, so buying slightly more than your estimate is always a smart move.
Your preparation style also plays a key role. Mashed potatoes are creamy and smooth, perfect as a classic side dish. Roasted sweet potatoes offer a savory, caramelized flavor, while baked potatoes are hearty and filling. Adding seasonings like butter, garlic, cinnamon, or honey can elevate the dish even further.
Other factors, such as appetite variations (hungry adults vs. light eaters), the number of other side dishes served, and whether guests will return for seconds, all influence how much you’ll need.
The good news? Sweet potatoes are versatile, budget-friendly, and packed with nutrients, making them an excellent choice for feeding a group. In this guide, we’ll break down serving sizes, preparation styles, cooking tips, and even creative ideas for using leftovers. Let’s make sure your sweet potato dish is perfectly portioned, flavorful, and enjoyed by everyone at the table! 🍠✨
