Yes, poultry seasoning can replace sage in a pinch. It is a blend of herbs that typically includes sage, thyme, rosemary, and marjoram. These herbs all have similar flavors, so they can be used to create a similar flavor profile. To use poultry seasoning as a substitute for sage, simply use an equal amount of poultry seasoning in your recipe. For example, if your recipe calls for 1 teaspoon of sage, you can use 1 teaspoon of poultry seasoning instead. It is important to note that this substitute may not be a perfect substitute for sage. The flavor of poultry seasoning may not be exactly the same as the flavor of sage, so your dish may taste slightly different.
