If you keep guessing every time you switch from oven to air fryer, you are wasting food and time. I have done it too. One day your chips are perfect, the next day they turn dry or soggy. That usually happens because oven settings do not match your airfryer settings. This Air Fryer Conversion Chart UK guide helps you convert oven cooking temperatures and air fryer cooking time without stress.

Temperature Conversion

Oven Temperature (Conventional)	Oven Fan Temperature (UK Fan)	Air Fryer Temperature (Celsius)	Air Fryer Temperature (Fahrenheit)
325°F / 165°C	150°C	170°C	340°F
350°F / 180°C	165°C	180°C	360°F
375°F / 190°C	175°C	190°C	375°F
400°F / 200°C	185°C	200°C	400°F
425°F / 220°C	200°C	210°C	410°F
450°F / 230°C	215°C	220°C	430°F

Most oven recipes are written for a conventional oven. Your air fryer works differently. It pushes hot air to circulate quickly around your food. That makes cooking quicker and more efficient.

Here is the simple rule you can follow in most UK kitchens. Reduce the oven temperature by about 20 celsius. Then reduce the cooking time by around 20 percent.

For example, if your oven recipes say 200°C for 30 minutes, you convert it to 180°C and check it at around 22 to 24 minutes in your air fryer basket. That small change prevents overcooking.

Still, times and temperatures can vary depending on the brand, basket size, and the ingredient thickness. Thin food cooks faster. Thick cuts need more time. Always check early instead of trusting the timer blindly.

Air Fryer Conversion Chart UK: Easy Oven to Air Fryer Conversion Guide

You do not need a complicated calculator to handle oven to air fryer conversion. You just need a simple reference you can glance at while cooking.

Here is a quick temperature conversion chart for common oven cooking settings in the UK.

Conventional oven at 160°C becomes about 140°C in an airfryer.

• 180°C becomes 160°C.
• 200°C becomes 180°C.
• 220°C becomes 200°C.

 

If a recipe says 25 minutes in a conventional setup, start checking at around 18 to 20 minutes when you air fry. Your appliance cooks faster because hot air moves tightly around the food inside the air fryer basket.

This guide works for most everyday dishes. You may need small adjustment for very large meals or when using a deep pan instead of a shallow tray.

Air Fryers Basics: Temperature, Timing and Cooking Time Explained

Before you start converting recipes, you need to understand the basics. An airfryer is basically a compact fan oven. It uses hot air to circulate around the food at high speed. That is why food turns crispy without deep fry oil.

Air fryer cooking time depends on a few things. The size of the ingredient matters. Thick chicken breasts take longer than thin strips. The way you place food in the basket also matters. If you overcrowd it, air cannot move freely and your food may turn soggy.

Preheat if your instruction manual recommends it. Some models heat instantly. Others perform better when you preheat for three to five minutes.

Flip food halfway through cooking. This helps it cook evenly. Shake fries so they brown on all sides. These small habits improve your cooking times and temperatures without guesswork.

Air Fry Conversion for Any Recipe: Bake, Fry and Cook Perfectly

You can convert almost any dish with a little common sense. If you bake a cake at 170°C for 35 minutes in a conventional oven, reduce it to around 150°C in your air fryer. Start checking at 25 minutes. Use a small pan that fits inside the basket. A silicone liner also helps prevent sticking.

If you cook chicken at 200°C for 40 minutes in oven cooking mode, convert it to 180°C and check around 30 minutes. Flip once so both sides brown evenly.

Frozen food cooks even quicker. Nuggets that need 18 minutes at 220°C in a conventional oven often cook in 12 to 14 minutes at 200°C when you air fry.

Many air fryer recipes for beginners fail because people forget to reduce heat. Always lower the temp slightly. Your appliance is more intense than you think.

Conversion Chart for Ninja, AF400UK, XL and Multi Basket Airfryer

Different models perform differently. A powerful brand like Ninja can cook slightly faster. The af400uk model, especially the xl and multi basket versions, spreads heat strongly across both baskets.

If you use a multi basket airfryer, food volume affects results. A half empty basket cooks quicker than a fully loaded one. When you cook in both trays, rotate or flip food to keep everything evenly cooked.

For most Ninja models including af400uk, reduce temperature by 15 to 20 celsius. Check food five minutes earlier than your estimate. If you notice the top browns too fast, reduce the temp slightly next time.

Test once before serving guests. After that, you will know exactly how your own appliance behaves.

Air Fryer Cookbook Guide: Accessories, Tips and Kitchen Basics

A good air fryer cookbook saves you trial and error. It gives exact air fryer cooking time, tested air fryer recipes, and smart adjustment tips.

The right accessory also matters. A silicone liner makes cleaning easier. A small baking pan helps when baking cakes. A rack lets you cook multi layer food. A proper tray that fits the basket keeps airflow strong.

Do not block airflow with oversized dishes. Hot air must move freely inside the air fryer basket. That is how you get a delicious and crispy finish.

Pat food dry before cooking. Too much moisture causes soggy texture. Shake fries halfway through. Preheat when baking. These basics sound simple, but they change results completely.

Oven Temperature Conversion Chart UK: Quick Reference for 2026

Here is your simple temperature conversion formula for daily use in the UK kitchen.

• Air fryer temp equals oven temp minus 20 celsius.
• Air fryer cooking time equals oven time minus about 20 percent.
• So 180°C becomes 160°C.
• 200°C becomes 180°C.
• 30 minutes becomes around 24 minutes.

If you want extra accuracy, you can use an online oven to air fryer conversion calculator as a reference. Still, always rely on visual signs. Look for golden colour. Check that food feels firm and cooked inside.

Once you practice converting recipes a few times, you will not even think about it. You will adjust temp and timing naturally. Your food cooks quicker, tastes better, and turns out crispy instead of soggy.

That is when your air fryer finally feels easy to use.
