What makes a liner “AF400-friendly”

AF400 baskets are wide and the fan-driven airflow is strong. Liners work best when they sit flat on the base, stay below the rim, and don’t create tall folds. Perforations can help airflow for chips and breaded foods, while higher walls help with oily or saucy meals.

When to use disposable paper liners

Disposable liners are brilliant for weeknight cooking when you want fast clean-up. They’re especially handy for marinated chicken, cheesy bakes, or anything that leaves sticky residue. After cooking, you lift the food out (carefully), bin the liner, and wipe the basket.

When to use reusable silicone liners

Reusable silicone liners trade convenience for lower waste. They’re heavier (so they’re less likely to lift) and they’re great for saucy foods where paper might soften. The downside is you still have to wash the liner after use, and silicone can stain with strongly coloured sauces over time.

If you cook a lot of sticky meals, it’s worth considering the reusable set: Check today’s price on Amazon UK.

Ninja AF400 Fit & Size Notes

Dual-zone cooking means your two baskets may be used differently: one zone might be oily, the other dry and crispy. That makes having more than one liner style useful. Fit matters because the AF400 airflow is powerful—oversized liners can bunch and reduce crisping, while undersized liners let drips escape into corners.

FAQ

Do liners reduce crispiness in the Ninja AF400?

They can if they block airflow. The best approach is a flat liner with minimal folds, plus turning or shaking food halfway through.

Which liner is best for sticky marinades?

Reusable silicone is often easiest for sauces because it’s sturdy and rinses clean. Paper also works, but can soften if it sits in liquid.

Should I line both baskets every time?

Not necessarily. Many owners line only the messier basket and keep the other basket bare for maximum crisping.

Are liners worth it if I only air fry occasionally?

Yes if you dislike scrubbing. If you cook rarely, the budget option can be a low-cost way to try liners without committing.
