I make air fryer banana chips every week — they’re light, crunchy, and far less greasy than store-bought options. What makes this version special is the balance of low oil, a quick lemon soak to keep color, and a precise air-fryer temperature that gives reliable crispness. After testing several cycles in two different air fryers, I’ve locked in timings and tips that work in most baskets.

Why Make This Recipe

Crisp, naturally sweet chips that satisfy a snack craving without deep frying.
Lower in added fat than traditional fried chips while keeping great texture.
Ready in about 25 minutes, perfect for after-school snacks or party bowls.
Easy to customize with cinnamon, chili powder, or a sprinkle of sea salt.
I love this recipe because it turns ripe bananas into a crunchy snack I don’t feel guilty about — and it taught me how precise slice thickness determines success; you’ll notice that too.
I often pair these with other air-fried snacks like crispy air fryer eggplant for a crunchy snack platter.

Recipe Overview

Prep time: 10 minutes (includes lemon soak and slicing)
Cook time: 12–18 minutes depending on thickness and air-fryer model
Total time: 22–28 minutes
Servings: 3–4 (from 3 medium bananas)
Difficulty: Easy
Cooking method: Dry-heat air frying at moderate temperature with single-layer cooking and a mid-cycle flip for even browning; use a mandoline or sharp knife for uniform slices.

My Experience Making This Recipe

I tested this across a 3.2‑quart basket fryer and a 6‑quart oven-style air fryer to account for airflow differences. The biggest discovery was that 1/8-inch slices hit the sweet spot: too thin burns, too thick stays chewy. I also learned that a very light oil mist improves color without making the chips greasy.

How to Make Air Fryer Banana Chips

Start by choosing 3 firm, yellow bananas with minimal brown spots — they slice cleaner than overly ripe fruit. Peel and slice into 1/8‑inch (about 3 mm) rounds, toss briefly in 1 tablespoon lemon juice to slow browning, and optionally add 1 teaspoon neutral oil for color. Arrange a single layer in the air fryer basket, set to 325°F (160°C), and cook 6–9 minutes, flip the slices, then continue 6–9 more minutes until edges are lightly golden and chips feel crisp when cooled. Expect a short carryover crisping as they cool; remove sooner if your slices are on the thinner side.

Ingredients (makes ~3 cups chips)

3 medium firm bananas (not overripe)
1 tablespoon fresh lemon juice
1 teaspoon neutral oil (avocado or grape seed), optional
Pinch of fine sea salt, or 1/2 teaspoon ground cinnamon for sweet chips

Equipment recommendations: mandoline or sharp chef’s knife, silicone-tipped tongs, perforated parchment or a silicone mat made for air fryers.

Expert Tips for Success

Slice uniformly: Use a mandoline set to 1/8 inch for consistent cooking and predictable crisping.
Don’t crowd the basket: Single layer cooking ensures even hot-air circulation; work in batches if needed.
Adjust temperature by thickness: For very thin chips, lower to 300°F (150°C) and watch closely for burning. For slightly thicker cuts, 325°F (160°C) yields a golden center without overbrowning.
Use a light oil mist: A 1‑tsp oil toss or spritz helps browning; skip it for lower fat but expect paler chips. Also, see techniques for getting great crunch with other air-fryer toppings like air fryer crispy fried onions in 5 easy steps.
Cool completely on a wire rack: Chips finish crisping as they cool; leaving them on a flat plate traps steam and makes them soggy.

How to Serve Air Fryer Banana Chips

Snack bowl: Serve plain with a sprinkle of sea salt or cinnamon sugar for movie nights.
Yogurt or smoothie topper: Crush a handful as a crunchy garnish for bowls and parfaits.
Charcuterie-style board: Mix with nuts and dried fruit for a tropical-themed spread.
Party dips: Pair with dark-chocolate hazelnut spread or a spiced yogurt dip for contrast.

Storage and Reheating Guide

Store completely cooled chips in an airtight container or glass jar with a tight lid at room temperature for best texture; they keep well for 3–4 days. Avoid refrigeration — humidity softens them quickly. For longer storage, flash-freeze in a single layer, then transfer to a freezer-safe bag for up to 1 month; re-crisp by air-frying at 300°F (150°C) for 3–5 minutes or baking on a sheet at 250°F (120°C) for 8–10 minutes. To revive a small, stale batch, pop them in the air fryer at 325°F (160°C) for 2–4 minutes — watch closely.

Recipe Variations

Cinnamon-sugar: Toss warm chips in 1 tablespoon coconut sugar + 1/2 teaspoon ground cinnamon for a sweet treat.
Savory plantain chips: Use green plantains sliced thin, season with 1/2 teaspoon smoked paprika and 1/4 teaspoon garlic powder.
Spicy chili-lime: Add 1/4 teaspoon cayenne and 1/2 teaspoon lime zest before air frying for a zesty kick.
No oil / paleo-friendly: Skip the oil entirely and rely on lemon juice for color; cooking time may be a minute or two longer.

Nutritional Highlights

Potassium-rich: Bananas provide potassium and vitamin B6, making these chips a mineral-rich snack.
Lower in added fat than fried alternatives when you use 1 teaspoon or less of oil.
Allergen information: Naturally gluten-free and dairy-free; check cross-contact if preparing near nuts or wheat products. Portion guidance: aim for a 1/2-cup serving (~30–40 chips depending on thickness) to keep portions sensible given natural sugars.

Troubleshooting Common Issues

Soggy chips: Likely causes are slices that are too thick, overcrowding, or storing while still warm. Slice thinner, cook single layer, and cool completely on a rack.
Burnt edges: Slices were too thin or temperature was too high. Lower heat by 10–25°F (5–10°C) and shorten time.
Sticking to basket: Either the basket surface needs a light oil mist, or use perforated parchment or a silicone mat rated for air fryers to prevent adhesion.

Frequently Asked Questions

Q: Can I use ripe bananas with brown spots?
A: Very ripe bananas will be sweeter but softer and harder to slice thinly; they tend to become chewy rather than crisp. Use firm, yellow bananas for the best chip texture.

Q: How thin should I slice bananas for chips?
A: Aim for about 1/8 inch (3 mm). This thickness crisps reliably without burning; thinner slices crisp faster but can burn, while thicker slices stay leathery.

Q: Can I make these in a convection oven instead?
A: Yes — arrange in a single layer on a wire rack set over a baking sheet and bake at 300°F (150°C) for 12–18 minutes, flipping halfway. Watch closely since oven airflow and timing vary.

Q: Are these healthy compared to store-bought banana chips?
A: Homemade air-fryer chips typically have much less added oil and no preservatives compared with commercial fried chips, so they’re a lower-fat, cleaner ingredient option; however, they still contain natural sugars from bananas, so enjoy in moderation.
