In a medium saucepan, add the butter and melt completely over medium heat.
Once the butter is melted, add the flour.
Quickly whisk until you have a paste-like mixture.
Slowly add the chicken bouillon while whisking.
Keep mixing and cooking until you have reached the desired thickness.
Salt and pepper to taste.
Notes
If your chicken bouillon was in the refrigerator, put it in the microwave for a few seconds. It should be at least at room temperature, if not hotter. Using a warm to hot chicken bouillon or broth will make for a smoother gravy and avoid lumps. If you need to make the gravy ahead of time, it will thicken up as it cools down. Just rewarm it with a splash of broth or bouillon. You can store the leftovers in the refrigerator for up to 3 days. It will also freeze well for up to 2 months.
