Understanding the Standard Medium Potato
Determining the right number of potatoes per serving is more accurate when based on weight rather than a simple count, as sizes can vary significantly even within a single bag. A medium potato is generally defined as weighing between 5 and 8 ounces (140 to 225 grams). For most side dishes, a good rule of thumb is to allocate approximately 1/2 pound (about 225 grams) of raw potato per person. However, the cooking method and the overall size of the meal can influence this amount.
Serving Size by Preparation Method
Different cooking methods and dishes affect the final volume and density of the potato, so the recommended starting amount can vary. Here's a breakdown for some of the most popular preparations:
Mashed Potatoes
For mashed potatoes, plan for about half a pound of raw potato per person. This typically translates to one medium potato per guest. If you're serving a larger crowd or know your guests have big appetites, you might consider increasing this to 3/4 pound per person. Don't be afraid of leftovers, as mashed potatoes are excellent for repurposing into other dishes like gnocchi or potato cakes.
Roasted Potatoes
Like mashed potatoes, roasted potatoes follow the half-pound rule per person. So, one medium potato per person is the standard. If potatoes are the primary side dish and your guests are big eaters, you may want to bump this up to a generous 3/4 pound per person. For smaller-sized potatoes like new potatoes, you will need to count 2-3 per person to reach the same weight.
Baked Potatoes
Baked potatoes offer a straightforward serving calculation: one medium-sized potato per person. Since they are served whole, it's easy to track. Always bake a few extra, just in case, especially for a large group, as some guests may have larger appetites.
Potato Salad
Since potato salad is typically served alongside other foods, the required amount is slightly less. A good starting point is between 1/4 and 1/2 pound of potatoes per person. This will yield a portion of about 1/2 to 3/4 cup of potato salad per guest. Waxy potatoes, like red or new potatoes, are often preferred for potato salad as they hold their shape better after cooking.
How to Calculate for a Crowd
Using a weight-based approach is the most reliable way to scale recipes. For a precise calculation, simply multiply the number of guests by the recommended weight per person. For example, to make mashed potatoes for 10 people, multiply 10 people by 0.5 pounds/person to get 5 pounds of raw potatoes needed. You can also add a small buffer for safety.
A Quick Reference Guide: Portioning Potatoes
| Preparation Method | Recommended Weight Per Serving (Raw) | Medium Potatoes Per Person (Approximate) |
|---|---|---|
| Mashed Potatoes | ½ lb (225g) | 1 |
| Roasted Potatoes | ½ lb (225g) | 1 |
| Baked Potatoes | 5–8 oz (140–225g) | 1 |
| Potato Salad | ¼–½ lb (125–225g) | ½ to 1 |
| Hearty Eaters/Fewer Sides | ⅔–¾ lb (300–340g) | 1.5–2 |
Factors Influencing Your Portion Size
Consider these additional factors when planning your potato side dish:
- Guest Appetites: Larger groups with hearty eaters might require slightly larger portions to ensure no one goes hungry. Always have a bit extra on hand.
- Other Side Dishes: If potatoes are just one of many side dishes, you can stick to the lower end of the recommended portion size. If it's a star player, aim for the higher end.
- Type of Potato: The variety you choose can affect how much liquid it absorbs. Starchy potatoes like russets can absorb more liquid and fluff up more when mashed, while waxy varieties are firmer.
- Preparation: Mashed and baked potatoes can feel more substantial, while a potato salad served cold may seem lighter.
Conclusion: Planning for Perfect Potatoes
The key to serving the right number of medium potatoes lies in understanding that one medium potato is roughly equivalent to half a pound. The cooking method, number of other sides, and your guests' appetites will ultimately determine if you need to stick to that rule, go a little over, or use less. For the most accurate results, rely on weight measurements. By following this guide, you can ensure a perfectly portioned potato dish every time.
