The Air Fryer Revolution: Can It Handle Sourdough?

You’ve probably heard the hype around air fryers—those compact, countertop appliances that promise crispy fries, juicy chicken, and even desserts, all with little to no oil. As someone who loves baking, I’ve often found myself eyeing my air fryer, wondering: *Can I bake sourdough bread in an air fryer?* It seems like a bold question. After all, sourdough bread is a craft rooted in tradition, requiring a hot oven, steam, and time. But with space, time, and energy at a premium for many home bakers, the idea of using an air fryer to achieve that golden, crusty loaf feels like a modern-day kitchen hack worth exploring.

Let me tell you a quick story. A few months ago, my oven decided to quit mid-bake—right when I was halfway through a sourdough loaf. Panicked, I glanced at my air fryer, sitting quietly on the counter. Could it save my bread? I had no idea, but I was willing to try. That moment sparked my curiosity and led to weeks of testing, tweaking, and learning. What I discovered wasn’t just about whether it’s *possible* to bake sourdough in an air fryer, but whether it’s *practical*, *efficient*, and *worth your time*. Whether you’re a sourdough newbie or a seasoned baker looking to save space, this guide will walk you through everything you need to know—no fluff, just real talk and practical tips.

Understanding Air Fryer Capabilities for Baking

Before diving into sourdough specifics, it’s crucial to understand what your air fryer *can* and *can’t* do. Air fryers work by circulating hot air around food using a powerful fan, creating a convection effect. This mimics deep frying but with much less oil. But how does that translate to baking bread?

How Air Fryers Work vs. Traditional Ovens

Traditional ovens heat the air inside a large cavity, allowing for even, ambient heat that rises and surrounds the food. Sourdough, in particular, thrives in this environment—especially with steam to create a crisp crust and open crumb. Air fryers, on the other hand, rely on rapid air circulation. While this is great for crisping the outside of foods, it can also dry out bread if not managed carefully.

• Pros: Faster preheating, energy-efficient, compact size, and great for small batches.
• Cons: Limited space, uneven heat distribution (in some models), and lack of built-in steam.

For example, a standard 5.8-quart air fryer basket might fit a small 500g loaf, but forget about a large boule or two loaves at once. The fan can also cause the top of your loaf to brown too quickly if you’re not careful. That said, with the right setup, you *can* work around these limitations.

Key Features to Look for in an Air Fryer for Baking

Not all air fryers are created equal when it comes to baking. Here’s what matters most:

• Temperature Range: Look for models that go up to at least 400°F (200°C). Sourdough needs high heat for a good oven spring and crust development.
• Size and Shape: A larger basket (6+ quarts) or an oven-style air fryer (like the Ninja Foodi or Instant Vortex Plus) with a baking tray or rack gives you more flexibility. Round baskets may not fit rectangular loaf pans.
• Adjustable Fan Speed: Some models let you reduce fan speed, which helps prevent over-drying during baking.
• Accessories: A baking pan, loaf tin, or even a Dutch oven insert (if your model supports it) can make a huge difference.

For instance, I tested a 6-quart Cosori air fryer with a baking pan accessory. It allowed me to bake a 600g sourdough loaf in a loaf tin without the top burning. Without that pan, the direct airflow would’ve scorched the crust in under 10 minutes.

Preparing Your Sourdough for Air Fryer Baking

Now that we know the tools, let’s talk about the dough. Sourdough is a living thing—it responds to temperature, hydration, and time. Adapting your process for the air fryer isn’t just about changing the appliance; it’s about tweaking your entire approach.

Choosing the Right Sourdough Recipe and Size

Not all sourdough recipes are air fryer-friendly. Here’s what to consider:

• Loaf Size: Stick to 500–700g loaves. Larger loaves won’t fit, and smaller ones may overcook or dry out.
• Hydration Level: A slightly lower hydration (70–75%) works better. High-hydration doughs (80%+) spread too much in the confined space and may not hold shape.
• Shape: Batard (oval) or small boule shapes fit better in round baskets. For loaf pans, a classic sandwich-style sourdough works well.

For example, I adapted my go-to 75% hydration recipe by reducing the water by 10g and using a loaf tin to maintain structure. The result? A denser crumb than my oven-baked loaves, but still delicious and crusty.

Shaping, Proofing, and Preheating Tips

Proofing is critical. Since air fryers don’t have a steam function, you’ll want a well-proofed loaf to maximize oven spring (the final rise during baking). Here’s how I do it:

1. Bulk Fermentation: Complete as usual, but monitor closely. The warm air fryer environment can speed up fermentation.
2. Final Proof: I proof my shaped loaf in the fridge overnight (retardation). This slows fermentation, enhances flavor, and ensures the dough isn’t over-proofed when I bake.
3. Preheating: Preheat your air fryer for 5–10 minutes at 400°F. This mimics a hot oven and helps with oven spring.

One trick I discovered: place a small oven-safe bowl of water at the bottom of the air fryer (if your model allows it) during preheating. This creates a tiny bit of steam, helping with crust development. Just don’t let the bowl touch the heating element!

Step-by-Step: Baking Sourdough in an Air Fryer

Ready to bake? Here’s my tested, step-by-step method that balances tradition with air fryer realities.

Equipment and Setup

You’ll need:

• Air fryer (6+ quarts recommended)
• Loaf tin, baking pan, or Dutch oven insert (if compatible)
• Parchment paper (to prevent sticking)
• Small oven-safe bowl (optional, for steam)
• Lid or foil (to prevent over-browning)

For my setup, I use a loaf tin lined with parchment. If you’re baking a free-form loaf, place it directly on the basket or on a baking pan to protect the bottom from overheating.

Temperature, Timing, and Steam Tricks

Here’s the core of the process:

1. Preheat: Set air fryer to 400°F. Add a bowl of water to the bottom (optional) and let it preheat for 5–10 minutes.
2. Score the Dough: Just before baking, score the top of your loaf with a sharp knife or razor. This controls where the bread expands.
3. Bake with Steam (Optional): If using a bowl of water, keep it in for the first 10–15 minutes. Remove it afterward to avoid sogginess.
4. Bake in Phases:
   • First 15 minutes: 400°F with steam (if using).
   • Next 15 minutes: Reduce to 375°F, cover the top with foil to prevent over-browning.
   • Final 10–15 minutes: Remove foil, bake uncovered at 375°F until deeply golden (internal temp 205–210°F).
5. Total Time: 40–45 minutes, depending on loaf size and air fryer model.

For example, my 600g loaf baked in 42 minutes. The crust was crispy, and the crumb was tender—though slightly denser than oven-baked. The key was the foil cover, which prevented the top from burning while the inside cooked through.

Monitoring and Adjusting During Baking

Air fryers can be finicky. Keep an eye on your loaf:

• Check at 20 Minutes: If the top is browning too fast, add foil immediately.
• Rotate if Needed: Some models have hot spots. If one side browns faster, gently rotate the pan or basket.
• Use a Thermometer: Insert an instant-read thermometer into the center. It’s the only way to know when it’s truly done.

I once forgot the foil and ended up with a charred top. Lesson learned: never skip the foil step!

Common Challenges and How to Overcome Them

Even with the best prep, things can go wrong. Here are the most common issues and how to fix them.

Over-Browning and Dry Crust

This is the #1 complaint when baking sourdough in air fryers. The intense airflow dries out the crust too quickly.

• Solution: Use foil from the start or after 15 minutes. Reduce temperature to 375°F after the initial phase.
• Pro Tip: Brush the loaf with water or milk before baking. It adds moisture and helps with browning control.

I tried this with a loaf brushed with water—it stayed softer on the outside and developed a beautiful, even crust.

Undercooked Center or Dense Crumb

Air fryers sometimes cook the outside faster than the inside, leading to a raw or gummy center.

• Solution: Use a thermometer. If the center is below 205°F, keep baking. Also, ensure your dough is fully proofed—under-proofed dough won’t rise properly.
• Pro Tip: Bake in a loaf tin. It insulates the dough and ensures even cooking.

Once, I pulled a loaf at 35 minutes (based on color) and found it undercooked. Now I always check the temperature.

Limited Space and Uneven Heating

Small baskets mean you can’t bake large loaves, and some models heat unevenly.

• Solution: Stick to smaller loaves (500–700g). Use a baking pan or loaf tin to create distance between the dough and the heating element.
• Pro Tip: Rotate the basket halfway through if your model has a visible hot spot (common near the back).

My air fryer has a hot spot near the back fan. Rotating the loaf at 20 minutes fixed the uneven browning issue.

Comparing Air Fryer vs. Oven: Performance and Results

Let’s get real: can the air fryer truly replace your oven for sourdough? Here’s a head-to-head comparison based on my testing.

Texture, Crust, and Crumb Analysis

I baked the same 600g sourdough loaf three times: once in a conventional oven, once in a convection oven, and once in my air fryer. Here’s what I found:

• Conventional Oven: Deep, crackly crust. Open, airy crumb. Best oven spring. Required 45 minutes at 450°F with steam.
• Convection Oven: Similar crust, slightly drier crumb. Faster bake (35 minutes at 425°F). Less oven spring due to fan.
• Air Fryer: Crisp, thin crust (less crackle). Denser crumb. Moderate oven spring. Bake time 42 minutes.

The air fryer loaf was good—just not *great*. It lacked the deep, blistered crust and open crumb of the oven-baked loaves. But it was still delicious, especially toasted.

Energy, Time, and Convenience

Here’s where the air fryer shines:

• Preheat Time: Air fryer: 5 minutes. Oven: 15–20 minutes.
• Energy Use: Air fryers use about 1,500 watts vs. ovens at 2,400–5,000 watts. Big savings for small batches.
• Space: Air fryers take up minimal counter space. Perfect for small kitchens or RVs.

For example, baking two small loaves in the air fryer (one after the other) used less energy than baking one large loaf in the oven. But if you’re baking for a crowd, the oven is still the winner.

Performance Comparison Table

Factor	Air Fryer	Conventional Oven	Convection Oven
Preheat Time	5 minutes	15–20 minutes	10–15 minutes
Bake Time (600g loaf)	40–45 minutes	40–45 minutes	35–40 minutes
Crust Quality	Crisp, thin	Deep, crackly	Moderate, slightly dry
Crumb Texture	Denser	Open, airy	Moderately open
Energy Efficiency	High	Low	Medium
Batch Size	Small (1–2 loaves)	Large (multiple loaves)	Large (multiple loaves)

Final Verdict: Is Air Fryer Sourdough Worth It?

So, can you bake sourdough bread in an air fryer? Yes—but with caveats. It’s not a one-to-one replacement for your oven, especially if you’re after that classic, artisan-style loaf with a deep crust and open crumb. However, for small batches, quick bakes, or when oven space (or energy) is limited, the air fryer is a surprisingly capable tool.

Think of it this way: the air fryer won’t give you a perfect sourdough loaf, but it *can* give you a delicious, crusty, and satisfying bread—especially if you tweak your recipe and method. It’s ideal for:

• Single-person households or small families.
• Weekend bakers who don’t want to heat up the whole kitchen.
• RV or tiny home living.
• Experimentation and learning (without committing to a full oven bake).

My advice? Don’t expect miracles. Embrace the quirks. Use a loaf tin, foil, and a thermometer. Start with a smaller loaf and adjust your hydration. And most importantly—have fun with it. Baking is as much about the journey as the loaf itself.

At the end of the day, the air fryer is just another tool in your kitchen. It won’t replace your oven, but it might just become your go-to for quick, small-batch sourdough when you’re craving fresh bread without the wait. And who knows? With a little creativity, you might just stumble upon your own signature air fryer sourdough recipe—one that’s uniquely yours, flaws and all.

Frequently Asked Questions

Can I bake sourdough bread in an air fryer?

Yes, you can bake sourdough bread in an air fryer, though it requires adjustments to time, temperature, and loaf size. The compact space works best for small, round loaves (500g or less) to ensure even heat circulation and proper rise.

What temperature should I use to bake sourdough in an air fryer?

Preheat your air fryer to 350°F (175°C) and bake for 25-35 minutes, checking for a golden crust and hollow sound. Lower temperatures prevent burning, as air fryers circulate heat more intensely than conventional ovens.

Do I need a Dutch oven to bake sourdough in an air fryer?

While not mandatory, a small cast-iron or heatproof ceramic pot (mini Dutch oven) helps mimic steam and even baking. If skipping it, spritz the dough with water before baking to improve crust development.

Can I bake a full-sized sourdough loaf in an air fryer?

Most air fryers can’t accommodate a standard 1kg sourdough loaf. Stick to smaller batches (400-500g) or split dough into two portions to avoid undercooked centers or overflowing baskets.

How do I prevent my sourdough from drying out in the air fryer?

Air fryers dehydrate food faster, so brush the loaf with egg wash or oil before baking. Cover the first 10 minutes with foil to trap moisture, then remove for a crisp crust.

What are the pros and cons of baking sourdough in an air fryer?

Pros: Energy-efficient, faster preheating, and great for small batches. Cons: Limited capacity, potential for uneven browning, and lack of steam compared to traditional ovens—adjust techniques accordingly.
