Homemade banana chips are a crisp, lightly sweet snack you can make with just ripe but firm bananas, a little oil, and salt. This recipe shows both an oven method and a stovetop fry method so you get a reliable result without guessing. You’ll end up with chips that snap instead of bend, with a clean banana flavor and no added preservatives.
The key to good homemade banana chips is slice thickness and moisture control. Too thick and they stay chewy; too thin and they scorch before drying. We’ll use a mandoline setting around 2 mm and a low, steady heat to pull out water slowly. If you enjoyed this, our strawberry banana smoothie is worth trying next.
Why You’ll Love These Homemade Banana Chips
- Only three base ingredients, all pantry-stable except the fruit
- Choice of oven-baked or fried so you control fat and texture
- Naturally gluten-free and can be made vegan with oil
- Chips stay crisp for days in a sealed jar
- Cheaper than store packs and free of sulfites
Ingredients You’ll Need
- 4 medium bananas, ripe but firm (about 700 g peeled)
- 2 tbsp coconut oil, melted (for brushing or tossing)
- 1/4 tsp fine sea salt
- 1 cup neutral oil (sunflower or canola) for frying method only
- 1 tsp lime juice, optional, to slow browning
The bananas should be yellow with no black spots; overly ripe fruit turns mushy when sliced. Coconut oil adds a faint sweetness that suits the fruit, while neutral oil keeps the fry version clean-tasting. Making this homemade banana chips at home is surprisingly straightforward once you know the key steps.
Ingredient Substitutions
Coconut oil: Replace with an equal amount of melted butter if you don’t need a vegan chip. Butter browns faster at oven temperatures above 160°C, so drop the heat to 150°C / 300°F and check at 20 minutes. Expect a richer, dairy-rounded flavor and slightly deeper color on the edges. The homemade banana chips works well for weeknight cooking when time is limited.
Neutral frying oil: Swap the cup of sunflower oil for the same volume of refined peanut oil for a higher smoke point. Peanut oil lets you hold 175°C / 350°F without smoking, giving a quicker crisp in 2 minutes per batch. The chip tastes cleaner and a touch nutty compared to canola. Storing leftover homemade banana chips correctly keeps it tasting good for days.
Lime juice: Use 1 tsp lemon juice instead if you have no lime. Both slow oxidation the same way, but lemon adds a sharper note that reads as slightly more tart. Skip entirely if you want pure banana sweetness with no citrus edge.
Fine sea salt: Replace with 1/4 tsp kosher salt, crushed fine. Kosher grains are larger, so they sit on the surface more; pulse in a mortar first or the chips taste unevenly salty. The flavor difference is minor once distributed. For another easy option, check out our beef birria low.
Step-by-Step Instructions
- Heat the oven to 160°C / 320°F if baking, or pour frying oil into a 20 cm heavy pan and set to medium heat. Line a tray with parchment.
- Peel bananas and brush with lime juice if using. Slice on a mandoline at 2 mm; lay slices in one layer without overlap.
- For oven: brush both sides with coconut oil, sprinkle salt, bake 25–30 minutes flipping at 15. They’re done when golden and crispy at the edges.
- For fry: test oil with a slice; it should bubble at once. Fry 4–5 slices at a time, 2 minutes per side, until pale gold and stiff.
- Drain fried chips on paper towel, salt lightly. Cool fully on a rack so steam escapes and they stay snap-able.
Pro Tips
Slice every banana to the same 2 mm so they finish together; uneven rounds mean some burn while others stay soft. A mandoline beats a knife for this consistency.
After baking, leave chips on the tray 10 minutes; residual heat drives off last moisture. Moving them too early traps steam under the chip and softens it.
For even browning in the oven, rotate the tray halfway and flip each round. Hot spots near the back wall can color slices before the center dries.
Read technique notes on frying basics if you’re new to oil temperature control. A clip-on thermometer removes the guesswork at 175°C / 350°F.
Common Mistakes to Avoid
Using spotty bananas is the fastest way to mush. Soft fruit tears on the mandoline and releases starch that gums the slice; firm yellow ones hold the round shape.
Crowding the fry pan drops the oil temp under 150°C, so slices soak fat and turn greasy instead of crisp. Fry in small batches and let oil recover between rounds.
Storing before fully cool traps vapor; the chips go limp by morning. Wait until they sound hollow when tapped, then jar them. You might also like our recipe keys.
Serving Suggestions
Pair a bowl with banana bread for a themed brunch spread. The crisp chips contrast the soft loaf nicely.
Crumble a few over mixed berry smoothie bowls to add crunch on top. They hold shape for about 10 minutes before softening in cold liquid.
Set them beside peach lemonade at a picnic; the sweet-tart drink balances the dry chip salt well.
Storage and Reheating
Keep cooled chips in an airtight jar at room temperature up to 5 days. Humid kitchens shorten that; drop a silica packet in the jar if yours is warm.
They don’t freeze well—condensation on thaw makes them sticky. If they soften, spread on a tray and crisp at 150°C / 300°F for 5 minutes, then cool again.
Don’t leave a full batch out over 2 hours in summer; sealed storage within that window keeps them safe and snap-worthy.
Recipe Variations
Cinnamon Sugar Version
After oiling, dust with 1 tbsp sugar mixed with 1/2 tsp cinnamon before baking. The sugar caramelizes at the edges by minute 22, giving a dessert chip with a faint spice finish.
Chili Lime Version
Sprinkle 1/4 tsp chili powder with the salt and lime juice step. The heat builds after the first bite and the citrus keeps the color bright through baking.
Plantain Swap
Use 3 green plantains peeled and sliced the same way for a starchier, less sweet chip. Fry at 180°C / 350°F for 3 minutes; they need more time than banana to dry through.
Air-Dried Version
Skip oil and lay slices in a dehydrator at 57°C for 8 hours. You get a pale, chewy chip closer to dried fruit; brush with oil after if you want snap.
Homemade Banana Chips
Description
Homemade banana chips are a crisp, lightly sweet snack made with just ripe but firm bananas, a little oil, and salt. This recipe gives both an oven and stovetop fry method so you get reliable, snappy chips with clean banana flavor and no preservatives.
Ingredients
Instructions
-
Heat oven or oil
Heat the oven to 160°C / 320°F if you are baking, or pour the 1 cup neutral oil into a 20 cm heavy pan and set to medium heat for the fry method. Line a baking tray with parchment so baked slices will not stick during the long dry-out.
-
Prep banana slices
Peel the bananas and brush the cut faces with 1 tsp lime juice if using it to slow browning. Slice each banana on a mandoline set at 2 mm and lay the rounds in a single layer without overlap so they dry evenly.
-
Oven bake chips
For the oven method, brush both sides of each slice with the 2 tbsp melted coconut oil and sprinkle with 1/4 tsp fine sea salt. Bake at 160°C / 320°F for 25–30 minutes, flipping at 15 minutes, until the chips are golden and crisp at the edges and snap rather than bend.
-
Fry stovetop chips
For the fry method, test the oil with one slice; it should bubble at once when the temperature is right around medium heat. Fry 4–5 slices at a time for 2 minutes per side until pale gold and stiff, then lift out with a slotted spoon.
-
Drain and salt
Drain the fried chips on paper towel to remove excess fat from the 1 cup neutral oil. Salt them lightly with the remaining fine sea salt while still warm so the seasoning adheres.
-
Cool on rack
Cool all chips fully on a wire rack so steam escapes and they stay snap-able. Wait until they sound hollow when tapped and no warmth remains before storing, or trapped vapor will soften them by morning.
