| How to Make Sourdough Starter With Yeast |
If you’ve ever wanted to bake sourdough bread but felt intimidated by traditional starters, you’re not alone. The good news is that learning how to make sourdough starter with yeast is one of the easiest and most reliable ways to get started. This method combines the classic sourdough flavor with the predictability of commercial yeast, making it perfect for beginners.
In this ultra-detailed guide, you’ll learn exactly how to make, feed, store, and use a sourdough starter made with yeast—using simple ingredients you probably already have in your kitchen.
What Is a Sourdough Starter With Yeast?
A sourdough starter with yeast is a fermented mixture of flour and water that also includes a small amount of commercial yeast. Unlike traditional wild sourdough starters that rely only on natural bacteria and wild yeast from the air, this version jumpstarts fermentation.
This method is ideal if:
- You want faster results
- You’re new to sourdough baking
- You live in a cold or dry climate
- You want consistent, reliable fermentation
Why Use Yeast in a Sourdough Starter?
Adding yeast doesn’t eliminate the sourdough experience—it enhances it for beginners. Here’s why many home bakers prefer this method:
- Faster activation: Starter becomes usable in days instead of weeks
- More reliable rise: Less chance of failure
- Milder sour flavor: Perfect for first-time sourdough eaters
- Great learning tool: Helps you understand fermentation basics
Ingredients for Sourdough Starter With Yeast
Basic Ingredients
- 2 cups all-purpose flour (unbleached recommended)
- 1½ cups lukewarm water (about 95°F / 35°C)
- 1 packet (or 2¼ teaspoons) active dry yeast
- 1 teaspoon sugar or honey (optional but helpful)
Optional Add-Ins
- Whole wheat flour (adds flavor and nutrients)
- Rye flour (boosts fermentation)
Equipment You’ll Need
- Glass or ceramic bowl or jar
- Wooden spoon or silicone spatula
- Clean kitchen towel or loose lid
- Measuring cups
Avoid metal containers, as they can interfere with fermentation.
How to Make Sourdough Starter With Yeast (Step-by-Step Instructions)
Step 1: Activate the Yeast
In a small bowl, combine the lukewarm water, yeast, and sugar (if using). Stir gently and let it sit for 5–10 minutes until the mixture becomes foamy. This confirms your yeast is alive and active.
Step 2: Mix the Flour
In a larger bowl or jar, add the flour. Slowly pour in the activated yeast mixture while stirring until a thick, pancake-batter consistency forms.
Step 3: Cover and Rest
Cover the container loosely with a towel or lid. Place it in a warm spot (70–80°F / 21–27°C). Let it rest for 24 hours.
Step 4: First Feeding (Day 2)
You should see bubbles forming. Discard half of the starter, then add:
- ½ cup flour
- ½ cup lukewarm water
Mix well, cover loosely, and let sit for another 24 hours.
Step 5: Continue Feeding (Days 3–5)
Repeat the feeding process once daily. The starter will become bubbly, airy, and slightly sour-smelling.
Step 6: Starter Is Ready to Use
Your starter is ready when it:
- Doubles in size within 4–6 hours after feeding
- Has lots of bubbles
- Smells pleasantly tangy
How to Feed and Maintain Your Starter
Daily Feeding (Room Temperature)
- Discard half
- Add ½ cup flour + ½ cup water
Weekly Feeding (Refrigerated)
If stored in the fridge, feed once per week and allow it to sit at room temperature for a few hours before returning it to cold storage.
How to Use Sourdough Starter With Yeast
This starter works beautifully for:
- Sourdough bread
- Pizza dough
- Sandwich loaves
- Pancakes and waffles
- Flatbreads
Use about 1 cup of active starter in most bread recipes.
Troubleshooting Common Problems
Starter Isn’t Bubbling
- Water may be too hot or cold
- Yeast may be expired
- Room temperature may be too low
Starter Smells Bad
A mild sour smell is normal. If it smells rotten or moldy, discard and start over.
Starter Too Thick or Too Runny
Adjust by adding small amounts of flour or water until thick but stirrable.

With proper feeding, it can last indefinitely.
Final Thoughts
Learning how to make sourdough starter with yeast is the easiest way to start your sourdough journey. It’s forgiving, fast, and beginner-friendly while still delivering delicious homemade bread.
