Match the goal of your recipe: for soups/stews, prioritize depth (mushroom broth, bouillon, miso).
Use the ratio in the table: replace vegetable broth 1:1 (or use the listed ratio) and stir until fully dissolved.
If your substitute is salty (bouillon, soy sauce), simmer 2-3 minutes first, then fine-tune with water or a small acid splash.
If it’s bland or too flat, add aromatics (garlic/onion powder, bay leaf) and simmer briefly to round out flavor.
Taste before serving: vegetable broth substitutions often need salt and acid adjustments to land the same “brothy” balance.
