How to Use Convection Oven As Air Fryer for Crispy Results
Most home cooks want the crispy, golden results of an air fryer but may not have the space or budget for another kitchen gadget. If you own a convection oven, you already have a powerful tool for air frying. With the right settings and a few smart tips, your convection oven can deliver the same crunch and flavor as a standalone air fryer. This guide explains exactly how to use your convection oven as an air fryer, including step-by-step instructions, practical examples, and expert advice for getting the best results.
What Is A Convection Oven?
A convection oven is different from a traditional oven because it uses a fan to circulate hot air around your food. This moving air cooks food more evenly and quickly. Air fryers work in a similar way, using a compact space and intense airflow to brown and crisp food. The main difference is that convection ovens are larger and can cook more food at once.
Why Use A Convection Oven As An Air Fryer?
If you want to eat healthier, save time, or avoid buying another appliance, using your convection oven as an air fryer is a smart choice. Here’s why:
- Space-saving: No need for extra equipment on your counter.
- Large capacity: Cook more food at once compared to most air fryers.
- Versatility: Bake, roast, and air fry in the same machine.
- Cost-effective: No need to spend money on a separate air fryer.
Many people don’t realize that convection ovens can often match or beat air fryers for crispiness, especially for larger meals.

What You Need To Get Started
Before you begin, gather these items:
- Convection oven (with convection or fan setting)
- Wire rack or perforated tray (for best airflow)
- Baking sheet (to catch drips and crumbs)
- Cooking spray or a little oil (optional for extra crispiness)
- Food to air fry (fries, chicken, vegetables, etc.)
A wire rack is key because it lets hot air surround your food. If your oven has an “air fry” function, you’re already set. Otherwise, look for the “convection bake” or “fan bake” setting.
How To Use Your Convection Oven As An Air Fryer
Here’s a simple guide to turn your convection oven into a powerful air fryer.
1. Preheat The Oven
Preheating is important for crisp results. Set your oven to the desired temperature, usually 20–25°F lower than the air fryer recipe suggests. Air fryers heat quickly, but convection ovens need a little more time.
- If the air fryer recipe says 400°F, set your convection oven to 375°F or 380°F.
- Let the oven preheat fully before adding food.
2. Prepare The Food
Cut food into even pieces so it cooks at the same speed. Pat dry with a paper towel—moisture stops food from crisping. Toss in a little oil or use cooking spray for better browning. Season as desired.
3. Arrange On A Rack
Place the food in a single layer on a wire rack or perforated tray. Avoid overcrowding. Put the rack over a baking sheet to catch drips. This setup lets hot air reach all sides of your food, which is essential for air frying.
4. Set The Convection Function
Turn on the convection or fan bake setting. If your oven has an “air fry” button, use it. If not, regular convection is fine.
5. Monitor Cooking Time
Food cooks faster with convection. Check 5–10 minutes before the recipe’s suggested time. Flip or shake food halfway through for even browning.
6. Finish And Serve
Once food is golden and crisp, remove it from the oven. Let it rest for a few minutes for extra crunch.
Key Differences: Air Fryer Vs. Convection Oven
It helps to see how convection ovens and air fryers compare. Here’s a side-by-side look:
| Feature | Convection Oven | Air Fryer |
|---|---|---|
| Cooking Space | Larger, fits more food | Smaller, limited batches |
| Fan Strength | Moderate | Very strong |
| Preheat Time | Longer (5–10 min) | Short (2–3 min) |
| Versatility | Bake, roast, air fry, broil | Mainly air fry, some roast/bake |
| Ease of Cleaning | More parts, larger trays | Smaller basket, easy clean |
Best Foods To Air Fry In A Convection Oven
Some foods work especially well in a convection oven “air fryer.” Here are popular choices:
- French fries: Homemade or frozen, both come out crispy.
- Chicken wings: Get a crunchy outside without extra oil.
- Vegetables: Broccoli, cauliflower, and carrots turn caramelized and sweet.
- Breaded items: Fish sticks, chicken tenders, and nuggets.
- Potato wedges: Thick or thin, they brown evenly.
- Tofu: Cubes become golden and chewy.
- Bacon: Flat, crispy, and less greasy.
- Mozzarella sticks: Melty inside, crunchy outside.
Surprisingly, convection ovens do very well with large batches of fries or wings—better than most air fryers.
Common Mistakes To Avoid
Many people make simple errors when using their convection oven as an air fryer. Here’s what to watch out for:
- Overcrowding the tray: Crowded food steams instead of crisps.
- Skipping the rack: Food sitting flat on a tray won’t brown as well.
- Not adjusting temperature: Using air fryer temperatures can burn food in a convection oven.
- Forgetting to flip: Even airflow means you still need to turn or shake food for best results.
- Using too much oil: A little goes a long way—too much can make food soggy.
Step-by-step Example: Crispy French Fries
Let’s walk through a classic recipe using your convection oven as an air fryer.
Ingredients
- 2 large russet potatoes
- 1–2 tablespoons vegetable oil
- Salt and pepper to taste
Instructions
- Preheat oven to 400°F (if air fryer recipe says 425°F).
- Wash and cut potatoes into even sticks.
- Soak in cold water for 30 minutes, then dry thoroughly.
- Toss potatoes with oil, salt, and pepper.
- Place fries in a single layer on a wire rack over a baking sheet.
- Bake for 20–25 minutes, flipping halfway, until golden and crisp.
- Remove and serve hot.
Time And Temperature Tips
- For thin fries, check at 18–20 minutes.
- For thicker wedges, it may take 30 minutes.
- Always adjust for your oven’s unique hot spots.

Useful Accessories For Better Results
A few small tools can improve your convection oven air frying:
- Wire racks: Let air reach all sides of food.
- Perforated trays: Special trays with holes for better airflow.
- Oven thermometer: Check if your oven’s temperature matches the dial.
- Silicone mats: For easy cleanup (use only if they allow airflow).
- Parchment paper: Use perforated versions to avoid blocking air.
Many beginners skip the wire rack, but it’s the single biggest upgrade for even crisping.
Cleaning Up After Air Frying
Cleaning is easier than you think. Let trays cool before washing. Soak racks or trays with stuck-on bits. Most parts are dishwasher-safe, but check your oven’s manual. Clean crumbs from the oven bottom to avoid smoke next time.
When A Convection Oven Is Better Than An Air Fryer
A convection oven can outperform an air fryer when you:
- Cook large batches (fries, wings, veggies for a party)
- Want to air fry and bake at the same time
- Need to cook on multiple racks
- Prefer not to buy another appliance
However, for quick snacks or very small batches, an air fryer may still win on speed and convenience.
When To Choose A Standalone Air Fryer
There are times when a standalone air fryer is the better choice:
- Very small kitchens with no oven space
- Cooking for just one or two people
- Needing the fastest possible cook times
- Wanting the easiest cleanup (small baskets)
If you find yourself air frying every day, a dedicated air fryer might be worth it. But for most families, a convection oven does the job well.

| 350°F | 325–330°F | +2–4 minutes |
Non-obvious Tips For Best Results
Many guides miss these advanced tips for better air frying in your convection oven:
- Preheat the rack and tray before adding food. This gives an instant sizzle, improving crispiness.
- Dry all food very well—even tiny drops of water can cause steaming instead of browning.
- Rotate trays if using multiple racks. Not all ovens have perfectly even airflow.
These details can make a noticeable difference, especially for breaded or battered foods.
Health Benefits Of Air Frying In A Convection Oven
Air frying uses much less oil—often 70–80% less than deep-frying. This cuts calories and fat. Plus, air-fried foods have fewer harmful compounds like acrylamide, which can form in deep-fried potatoes. You get the flavor and crunch you want, with less guilt.
When Not To Air Fry In A Convection Oven
Some foods don’t work well in a convection oven:
- Battered foods (the fan can blow wet batter off)
- Delicate pastries (may dry out too much)
- Very small items (can get blown around by strong airflow)
In these cases, use traditional baking or pan-frying for better results.
