Super Soft White Rice Porridge Toast: The Fluffiest Bread You’ll Ever Make
Oh my gosh, let me tell you about the best bread recipe I’ve tried all year! This super soft white rice porridge toast is like a hug from a cloud—fluffy, chewy, and so moist it’ll make you forget store-bought bread exists. I’m a total bread nerd, always chasing that perfect “glove film” when kneading dough (you know, when the dough stretches into a thin, strong sheet without tearing?). But this recipe? It’s easier than I thought, thanks to the rice porridge trick!
First off, the star here is the white rice porridge. Instead of just water or milk, adding cooled rice porridge gives the bread *that extra softness* you can’t get anywhere else. It’s almost like a secret ingredient for Japanese-style soft bread. Let me show you how to make it step by step—trust me, even if you’re new to kneading, you’ll nail this!

What You’ll Need: Ingredients List
Let’s start with the basics. You’ll need these items (I’ll list measurements, but adjust to your taste!):
- High-gluten flour (I used Japanese Black Gold wheat flour—so good for elasticity!)
- Cooled white rice porridge (soft, thick consistency—cooled is key to keep the yeast happy!)
- Granulated sugar
- Salt
- Water (for dissolving yeast)
- Active dry yeast
- Butter (softened, not melted)
- Egg (optional, but helps with browning and moisture)
250g (if you don’t have Japanese flour, regular high-gluten flour works too!)
120g (you can make this by boiling rice + water until soft, then cool it down)
20g (balances the rice’s sweetness)
2g (enhances flavor, trust me)
15g (room temp works best)
2.5g (make sure it’s fresh! Old yeast = flat bread)
20g (adds richness and stretch)
1 (if you have it, skip if vegan and use a splash of plant milk instead)
Pro tip: If you’re not into making your own rice porridge, you can buy pre-made *onigiri* rice balls (the porridge is leftover from the rice after making onigiri—genius!). Just squeeze the porridge out gently, cool it, and use it!
How to Make the Super Soft Rice Toast: Step-by-Step
Alright, let’s get baking! This is where the magic happens. I’ll walk you through each step with photos to follow along (they’re all linked above, just scroll down or check the image captions).
Step 1: Gather & Prep Your Ingredients
First, make sure all your ingredients are at room temperature—especially butter and the rice porridge! The rice porridge needs to be cooled completely (if you just made it), or it’ll kill the yeast. I use leftover rice from dinner sometimes, so it’s already cool by morning. Let’s check the quantities again to avoid mess-ups later!

Step 2: Mix the Base Dough (No Yeast or Butter Yet!)
Combine all ingredients except yeast and butter in a large bowl. That includes the flour, cooled rice porridge, sugar, salt, water, and egg (if using). Now, mix them with your hands or a dough hook until a shaggy dough forms. You don’t need to knead it yet—just get it to stick together. The goal is to “rest” the dough first so the gluten starts to relax.
Cover the bowl with plastic wrap and let it sit at room temperature for 30-60 minutes. I usually do 30 minutes because I’m impatient, but an hour is fine too. This “autolyse” step makes the dough easier to knead later and gives it better texture!

Step 3: Check for Early Gluten Development
After resting, the dough should look smoother and less “dry.” If you can stretch a small piece into a thin film (not perfect yet, but better than before), that’s a good sign! This is the “pre-knead” check—you’re halfway there!

Step 4: Add Yeast & Start Kneading
Now, dissolve the yeast in the 15g water (just stir until it’s fully mixed). Pour this yeast water onto the dough. At first, the dough will feel super sticky—don’t panic! That’s normal. Start kneading by hand: use the “press, fold, stretch” method. Press down the dough, fold the sides over, and stretch gently. It might take 5-10 minutes, but keep going! Eventually, the stickiness will fade, and the dough will start to “hold” together.

Step 5: Incorporate Butter
Once the dough is less sticky, add the softened butter (let it sit out for 30 minutes to soften, not melt!). Tear the butter into small pieces and work it into the dough. This is the most tedious part, but so worth it! Keep kneading, pressing, and folding until the butter is fully absorbed. You’ll feel the dough get smoother as the butter coats the gluten.

Step 6: Achieve the Perfect Glove Film
Now, the final kneading part! Stretch a piece of dough—if it forms a thin, strong, and almost see-through film without tearing, you’ve got your “glove film”! This is the sign your dough is perfectly kneaded, and it’s what makes the bread soft yet elastic. If it’s still tearing, knead a few more minutes. You can use a stand mixer here too—just set it to low and knead for 8-10 minutes, then check the film.

Step 7: First Fermentation (Bulk Rise)
Shape the kneaded dough into a smooth ball and place it in a clean, oiled bowl. Cover with a damp cloth or plastic wrap and let it rise at room temperature (25-28°C is ideal, but if your kitchen is cool, just let it sit longer) until it’s doubled in size. This might take 1-2 hours, depending on the temperature. To check if it’s done, press a finger into the dough—if it springs back slowly, it’s ready!

Step 8: Deflate & Divide the Dough
Once risen, take the dough out of the bowl and press it gently with your hands to release air bubbles. You can also “punch” it down. Then, divide the dough into 3 equal pieces (about 180-200g each). Roll each piece into a smooth ball with your hands, then cover with a damp cloth and let them rest for 20 minutes. This “bench rest” helps the gluten relax so rolling is easier.

Step 9: Roll & Shape the Loaves
Take one rested dough ball and roll it into an oval shape with a rolling pin. Try to keep the edges even—no need to be perfect! Then, starting from the top, roll it up tightly like a cinnamon roll. Pinch the seam to seal it. Do this for all 3 dough balls, then place them into a loaf pan (I use a 9×5 inch pan, but any will work). Cover with a damp cloth and let them rise again for 45-60 minutes.

Step 10: Second Fermentation (Final Rise)
Wait, how do you know when the second rise is done? The dough should be puffed up, and if you press the top gently, it should spring back slowly. To help with rising, I place the pan in the oven with the light on (or near a warm spot) and put a bowl of warm water next to it—this creates a humid environment, which makes the bread even fluffier. Perfect for that “Japanese soft bread” vibe!

Step 11: Bake to Golden Perfection
Preheat your oven to 175°C (350°F). If your oven runs hot, check with an oven thermometer. Once the dough is puffed to 90% of the pan size (almost full), slide it into the oven, lower rack, and bake for 45 minutes. Halfway through, if the top is browning too fast, cover loosely with foil to prevent over-browning.

Step 12: Cool & Enjoy!
Take the bread out of the oven and let it cool in the pan for 10 minutes, then transfer to a wire rack to cool completely. Wait, don’t rush this! Letting it cool slowly keeps the crumb soft. Once cool, slice it—you’ll see the soft, airy texture inside. Toast it with a little butter, or eat it plain—it’s delicious either way!

Pro Tips for Flawless Rice Porridge Toast
Let me share my best tips to avoid common mistakes:
- Use fresh yeast—old yeast won’t make the bread rise properly. If you don’t have active dry yeast, use instant yeast (but adjust the amount to 3g, since instant is more potent).
- Control the oven temperature—175°C is perfect, but if yours is too hot, lower to 160°C. Burned edges are the worst, so check at 20 minutes and cover with foil if needed!
- Resting is key—the 30-minute autolyse and 20-minute bench rest help the dough develop better structure. Don’t skip these steps!
- Bread machine shortcut—if you’re lazy like me, use a bread machine! Set it to the “dough” cycle (10 minutes), then add yeast and butter at the right time. It still works with the same steps—just follow the machine’s instructions.
- Store properly—keep the toast in an airtight container at room temp for 2-3 days, or freeze slices for later. If it gets dry, spray a little water on it before toasting!
