How To Make Onion Chips In Air Fryer
This is the core method for perfect onion chips every single time. Follow these steps closely for the best results.
Ingredients You Will Need
- 2 large onions (yellow, white, or sweet)
- 1 tablespoon olive oil or avocado oil
- 1 teaspoon salt
- 1/2 teaspoon garlic powder
- 1/2 teaspoon paprika (optional for color and flavor)
- Cooking spray for the air fryer basket
Essential Equipment
- Air fryer
- Sharp knife or mandoline slicer
- Large mixing bowl
- Paper towels or a clean kitchen towel
- Tongs or a fork for tossing
Step-by-Step Instructions
Step 1: Prepare the Onions
Peel your onions and cut off the ends. Slice them into very thin, even rings, about 1/8-inch thick. A mandoline slicer is ideal for uniform thickness, but a sharp knife works if you’re careful. Separate the rings with your fingers and place them in a large bowl.
Step 2: Dry the Onion Rings
This step is crucial for crispiness. Pat the onion rings thoroughly with paper towels or a clean cloth. You want to remove as much surface moisture as possible. Damp onions will steam instead of crisp up in the air fryer.
Step 3: Season the Rings
Drizzle the dried onion rings with oil. Toss them gently to coat every piece lightly. Sprinkle the salt, garlic powder, and any other seasonings over the top. Toss again until the seasoning is evenly distributed. Don’t be shy with the tossing—it ensures every chip gets flavor.
Step 4: Preheat the Air Fryer
Set your air fryer to 350°F (175°C). Let it preheat for about 3 minutes. Preheating helps the chips start cooking immediately for a better texture. While it heats, lightly spray the air fryer basket with cooking spray to prevent sticking.
Step 5: Cook in Batches
Place the onion rings in the basket in a single layer. Do not overcrowd them; they need space for air to circulate. You will likely need to cook in 2 or 3 batches. Cook for 8-12 minutes, shaking the basket or turning the rings with tongs halfway through. Watch closely after the 8-minute mark, as they can burn quickly.
Step 6: Cool and Crisp
Once the chips are golden brown and crispy, remove them from the air fryer. Let them cool on a plate or rack for 5 minutes. They will continue to crisp up as they cool. Repeat with the remaining batches. Serve immediately for the best texture.
Choosing the Right Onion
Not all onions are created equal for chips. Here’s a quick guide:
- Yellow Onions: The standard choice. They have a strong, classic onion flavor that mellows and sweetens when cooked.
- White Onions: Slightly sharper and more pungent than yellow onions. They make for a very flavorful chip.
- Sweet Onions (Vidalia, Walla Walla): These are excellent for a milder, naturally sweeter chip. They have a higher water content, so drying them well is extra important.
- Red Onions: They work but can become slightly chewier. Their beautiful color makes for a visually appealing chip, though.
Pro Tips for Perfect Crispiness
- Dry Thoroughly: We can’t stress this enough. Moisture is the enemy of crisp. Take the time to pat those rings dry.
- Use a Mandoline: Even slices cook evenly. Uneven slices mean some chips will burn while others are still soft.
- Don’t Overcrowd: Air flow is the magic of the air fryer. Give the chips room to breath in the basket.
- Shake the Basket: Moving the chips around halfway through cooking prevents hot spots and ensures even browning.
- Let Them Cool: They might seem a bit soft when hot, but they crisp up significantly as they cool down.
Creative Seasoning Ideas
Once you master the basic recipe, try these seasoning blends to mix things up. Just toss the oiled rings with your chosen mix before air frying.
Spicy Buffalo
- 1 tsp garlic powder
- 1 tsp onion powder
- 1/2 tsp cayenne pepper
- 1/2 tsp salt
Smoky BBQ
- 1 tsp smoked paprika
- 1/2 tsp brown sugar (or coconut sugar)
- 1/2 tsp garlic powder
- 1/4 tsp chili powder
Simple Parmesan Herb
- 2 tbsp grated Parmesan cheese
- 1 tsp dried Italian herbs
- 1/2 tsp garlic salt
Everything Bagel
- 1 tbsp everything bagel seasoning
- 1/2 tsp onion powder
Common Mistakes to Avoid
Even easy recipes can have pitfalls. Here’s what to watch out for.
- Skipping the Drying Step: This leads to soggy, steamed onions instead of crispy chips. It’s the number one reason recipes fail.
- Uneven Slicing: Thick pieces won’t get crisp, and very thin pieces can burn. Aim for consistent thickness.
- Using Too Much Oil: A light coating is all you need. Excess oil makes the chips greasy and can cause them to burn.
- Not Preheating: Starting in a hot air fryer gives you that instant sizzle needed for good texture.
- Forgetting to Shake: Without shaking, the chips on the bottom might burn while the top ones are undercooked.
Serving Suggestions
Onion chips are incredibly versatile. Here are a few ways to enjoy them:
- As a Standalone Snack: Enjoy them straight from the bowl. They’re perfect for movie night.
- With Dips: Serve with ranch dressing, blue cheese dip, spicy sriracha mayo, or a cool yogurt-based dip.
- As a Topping: Crumble them over soups, salads, baked potatoes, or casseroles for a fantastic crunchy topping.
- Alongside Burgers or Sandwiches: They make a great side instead of fries or potato chips.
Storing and Reheating
Onion chips are best eaten fresh. However, if you have leftovers, you can store them in an airtight container at room temperature for 1-2 days. They will lose some crispness over time.
To re-crisp them, place them back in the air fryer at 350°F for 1-2 minutes. This usually brings them back to life. Avoid using the microwave, as it will make them soft and chewy.
Nutritional Information
One of the best parts of this recipe is how it lightens up a typically fried snack. A serving (about 1/4 of the recipe) has roughly:
- Calories: 60-70
- Fat: 3-4g

Compare this to deep-fried versions or many store-bought chips, and you’ll see a big difference. You’re also avoiding artificial ingredients.
FAQ Section
Why are my onion chips not crispy?
The most likely cause is excess moisture. Make sure you dry the onion rings very well with towels before adding oil and seasoning. Also, avoid overcrowding the air fryer basket, as this traps steam.
Can I use frozen onion rings for this?
This recipe is designed for fresh onions. Frozen onion rings are usually battered and meant for deep frying. They won’t get the same crisp, chip-like texture in the air fryer with this method.
How long do you put onions in the air fryer?
For thin slices at 350°F, it takes 8 to 12 minutes. Cooking time can vary based on your air fryer model and the thickness of your slices. Always check and shake the basket halfway through.
Can I make these without oil?
You can, but the results will be different. A very light spray of oil helps the seasoning stick and promotes browning and crispiness. Without it, the chips may dry out and be more prone to burning.
What’s the best air fryer temperature for onion chips?
350°F (175°C) is the sweet spot. It’s hot enough to crisp them up without burning them too quickly. Some recipes suggest 380°F, but at that temperature, you need to watch them extremly closely to prevent burning.
Can I use other vegetables?
Absolutely! This method works great for other sturdy vegetables like kale (for kale chips), zucchini, or even carrot slices. Just adjust the cooking time based on the vegetable’s water content.
Troubleshooting Guide
If something went wrong, here’s how to fix it next time.
- Chips are Burned: Your temperature was too high, or you cooked them too long. Try reducing the temp to 340°F and checking them earlier. Also, ensure your slices are even.
- Chips are Soggy: You didn’t dry the onions enough, or you overcrowded the basket. Pat more thoroughly and cook in smaller batches.
- Seasoning Fell Off: You probably added seasoning after the oil dried. Always toss the seasoning with the oiled onions so it has something to adhere to.
- Chips are Unevenly Cooked: You didn’t shake the basket during cooking. Always shake or turn them at the halfway point for even air circulation.
Making onion chips in your air fryer is a simple, rewarding process. With a little practice, you’ll be able to make a batch quickly whenever the snack mood strikes. The key is in the preparation: thin, even, dry slices and careful seasoning. Remember to cook in batches for the best airflow and crispness.
Experiment with different onion types and your favorite seasonings to find your perfect combination. This recipe is a fantastic base for creativity. Whether you enjoy them plain, with a dip, or as a garnish, these crispy homemade chips are sure to become a regular in your kitchen. They’re a proof that healthy snacks can be full of flavor and satisfying crunch.
