Plain water cooks potatoes perfectly well, but it doesn't add much flavor. Chicken broth allows the potatoes to absorb savory flavor while they cook, making the finished dish taste richer without requiring complicated ingredients.
Make Them Even Better
For extra creamy mashed potatoes, mix in sour cream or a little cream cheese.
You can also add roasted garlic, Parmesan, fresh herbs, or chopped chives for an easy flavor upgrade.
Final Tip
Next time you make mashed potatoes, don't automatically reach for plain water. Cooking them in broth is a small change that can give this classic side dish a much deeper and more satisfying flavor.
