I have left over broth but not enough for what recipes require
Are you channeling your best self with this comment? (If you're not sure, check out our Code of Conduct.)
What are you cooking? I may be giving you a omg-this-is-way-more-comlpicated-than-it-should-be answer but here goes: Some recipes may not miss the broth and some/all water would work just fine. When I've been in this pinch before, I've made a cheaters broth by heating some olive oil in a pot over medium heat, adding some veggie scraps (celery ends, carrot peels, onion ends, garlic, herb stems) until richly browned, and then adding broth and water to bring to a simmer for an hour or so. If you don't have veggie scraps, see what's in your spice cabinet--wrap (and tie the top tightly) a combination of aromatic powders (garlic, onion) and dried herbs in cheese cloth or a muslin bag and steep in boiling water like a tea.

Depends on what you're making. I like to keep powdered broth in the pantry for cases just like this where I run short on broth. 1 teaspoon to 1 cup of water and it works great.
The short answer: Yes.

depending on the recipe, you probably can do that, but can you let us know what the recipe is?
