Yeast Substitutes – 5 Best Bread Leavening Options
The best substitute for yeast is Baking Powder at a 1 packet (2 1/4 tsp) yeast = 1 tbsp baking powder per 2 cups flour ratio. It works best for flatbreads, pizza crust (quick version), naan. There are 4 other alternatives below, each with exact ratios and usage notes.
Best Substitute
Baking Powder
1 packet (2 1/4 tsp) yeast = 1 tbsp baking powder per 2 cups flour
Creates a quick-bread texture instead of yeast-bread texture. No rise time needed but the result will be denser and lack yeast's flavor.
What are the other substitutes for yeast?
Baking Soda + Acid
1 packet yeast = 1 tsp baking soda + 1 tsp acid (vinegar or lemon juice) per 2 cups flour
Provides immediate leavening without rise time. Mix baking soda into dry ingredients and acid into wet, then combine quickly.
Sourdough Starter
1 packet yeast = 1 cup active sourdough starter (reduce flour and liquid by 1/2 cup each)
Natural yeast and bacteria provide complex flavor and leavening. Requires much longer rise time (4-12 hours). Adjust flour and water.
Beer (in pizza/bread dough)
Replace liquid in recipe with equal amount of beer
Beer contains yeast and CO2 that provide some leavening and yeasty flavor. Works best when combined with baking powder for extra lift.
Instant Yeast (for active dry yeast)
1 tsp active dry yeast = 3/4 tsp instant yeast
Instant yeast is more potent and doesn't need proofing. Add directly to dry ingredients. Use slightly less than active dry.
What should you know before substituting yeast?
No substitute truly replicates yeast's flavor and texture in bread. Baking powder alternatives create quick-bread texture, not the chewy, airy crumb of yeasted dough. Always proof active dry yeast in warm water (105-110°F) to ensure it's alive before using.
How do you substitute yeast in a recipe?
A living organism that ferments sugars to produce carbon dioxide and alcohol, used as a leavening agent in bread, pizza dough, and other baked goods.
The best substitute for yeast depends on what role it plays in your recipe. Our top recommendation is Baking Powder (1 packet (2 1/4 tsp) yeast = 1 tbsp baking powder per 2 cups flour), which works well for flatbreads, pizza crust (quick version), naan.
If you need a different option, Baking Soda + Acid (1 packet yeast = 1 tsp baking soda + 1 tsp acid (vinegar or lemon juice) per 2 cups flour) is another reliable choice. Provides immediate leavening without rise time. Mix baking soda into dry ingredients and acid into wet, then combine quickly.
When substituting yeast, consider the flavor profile, texture, and cooking method of your recipe. For vegan alternatives, look for the options marked with the vegan badge above.

Frequently Asked Questions
Can I make bread without yeast?
Yes, but the texture will be different. Use 1 tablespoon baking powder per 2 cups flour for a quick-bread style, or sourdough starter for traditional fermented bread (requires longer rise time).
What is the difference between active dry yeast and instant yeast?
Active dry yeast needs to be dissolved in warm water before use (proofing). Instant yeast can be mixed directly into dry ingredients and uses 25% less-3/4 tsp instant equals 1 tsp active dry.
How do I know if my yeast is still alive?
Dissolve the yeast in warm water (105-110°F) with a pinch of sugar. If it foams and bubbles within 5-10 minutes, it's active. If nothing happens, the yeast is dead and should be replaced.
