How to Make Bagel Chips? Crispy Oven and Air Fryer Recipes

Slice day-old bagels about 1/8 to 1/4 inch thick, brush both sides with olive oil and a light coat of seasoning, then bake at 325 to 350 degrees Fahrenheit for 12 to 20 minutes, flipping halfway through until the edges turn golden and the centers feel dry. A single batch of plain bagels can turn into five different flavors, costs roughly a quarter of what the store charges per ounce, and rescues bagels that would otherwise go stale on the counter.

Below, you’ll find the tools, slice thickness, oven and air fryer timings, a modular seasoning matrix, and the fixes for the two failures that wreck most home batches.

Why Homemade Bagel Chips Outpace the Store-Bought Bag

A 6-ounce bag of branded bagel chips runs about $4 to $5 at most US grocery stores, which works out to roughly 70 to 85 cents per ounce. Three plain bagels from the bakery aisle cost around $3 total and weigh in at about 14 ounces before slicing. Spread the cost across every chip you bake, and your per-ounce price drops to roughly 20 cents, less than a third of the shelf price, even after factoring in olive oil and seasoning.

Cost is only part of the story. The bag you grab at the store usually lists sunflower oil, yeast extract, and maltodextrin in the first four ingredients, plus 110 to 150 mg of sodium per serving. When you bake at home, you pick the oil (extra-virgin olive oil is fine), measure the salt (a pinch of kosher salt per chip), and decide whether to add anything at all. Day-old bagels, the ones heading toward the trash anyway, slice cleaner than fresh ones because the crumb has firmed up overnight, and that slightly drier texture means the chips crisp without turning leathery.

One base recipe also unlocks more variety than a single store-bought flavor ever could. The same sheet of sliced bagels can split into a savory garlic-onion batch, a cinnamon-sugar dessert batch, and an everything-bagel appetizer batch with whatever’s already in the pantry. Each variation uses the same bake time and temperature, so the second and third trays slide in while the first one cools.

Four Practical Wins From a Single Sheet Pan

• ▸Lower cost per ounce. Roughly a quarter of the branded bag price once oil and salt are factored in.
• ▸Cleaner ingredient list. Olive oil, kosher salt, and your spice rack replace preservatives and maltodextrin.
• ▸Less food waste. Day-old bagels that would have gone stale become a snack with a two-week shelf life.
• ▸Built-in flavor variety. One sliced batch produces savory, sweet, and everything-style chips from the same bake.

Tools, Bagel Types, and the 1/8-Inch Slice Standard

A serrated bread knife plus a chopstick rail is the safest way to hit the target thickness without a mandoline. Lay two chopsticks or wooden dowels parallel to the bagel on a cutting board, rest the knife blade against them, and the blade physically cannot drop below the thickness you’ve set. Most chopsticks measure about 1/8 inch across their narrow edge, so two stacked together give you roughly 1/4 inch, which is the sturdy end of the chip range. A US quarter measures about 0.07 inch and a nickel about 0.08 inch, so a slice slightly thicker than a stacked nickel is the perfect 1/8-inch snap chip. Aim for 1/8 inch if you want a delicate snap that shatters when bitten, and 1/4 inch if you want a sturdier scoop for thick dips like hummus or whipped feta.

Which Bagels Work and Which Ones to Skip

Plain, sesame, everything, and rye bagels produce the most even browning because their crust-to-crumb ratio is balanced. Heavily glazed varieties, like cinnamon-raisin or maple-glazed, scorch at the edges before the center dries out, and stuffed bagels (those with cream cheese or jam already inside) collapse and leak. Sourdough works well if you slice on the thinner side, since its open crumb can brown unevenly when left too thick.

Those slice and bagel choices only pay off once the oven actually crisps them correctly.

The Core Seasoning Pantry

• ▸Olive oil. The brush-on fat that carries flavor and drives browning; about 1 tablespoon per bagel half.
• ▸Kosher salt. Flaky crystals adhere better than table salt and add a clean finish.
• ▸Garlic powder. The workhorse savory note; pairs with almost any bagel base.
• ▸Onion powder. Adds sweetness and depth without the moisture of fresh onion.
• ▸Cinnamon and sugar. The base for any sweet variation; mix at a 1:2 ratio.
• ▸Grated Parmesan. Sprinkled on during the last two minutes for a cheesy crust.

The Oven Method: Temperature, Timing, and the Midway Flip

Preheat to 325°F for slices on the thicker side (1/4 inch) and 350°F for thin snap-style chips (1/8 inch). The lower temperature gives the inside of a thick slice time to dry out before the edges scorch. Lay the slices in a single layer on a parchment-lined baking sheet, brush the top face with olive oil, season, then flip and repeat on the second side. Crowding the pan traps steam and leads to chewy centers, so leave at least half an inch between each slice.

Total Bake Time and the Halfway Flip

Thin slices need 12 to 14 minutes total. Thicker slices need 16 to 20 minutes. At the halfway mark, flip every slice with a pair of kitchen tongs so the bottom face gets the same direct heat as the top. Pull the tray when the edges look golden-brown and the centers feel dry to a light tap; residual heat on the sheet pan finishes the crunch over the next 2 to 3 minutes as the chips cool on a wire rack.

Reading the Doneness Signals

“Pull chips when edges turn golden and centers feel dry to the touch, then cool them on a wire rack so the underside doesn’t steam itself soft.

Color is the most reliable cue. Pale chips need another two minutes; deep brown means the corners will taste bitter once cool. Sound matters too. A properly baked chip taps like a thin piece of wood when flicked, while an underdone one sounds muffled and dense.

The Air Fryer Method: Faster Batches Without the Crowding

An air fryer turns the same recipe into a 6 to 8 minute job per batch, but only if you respect the single-layer rule. Set the temperature to 300°F, arrange slices in one flat layer with space around each one, and cook for 6 to 8 minutes. The lower temperature compensates for the more intense convective heat inside the basket; running at 350°F in an air fryer scorches the edges before the centers crisp.

Timing, Shaking, and Sweet-Seasoning Adjustments

Check the basket at the 5-minute mark. Flip or shake every slice once at the halfway point to mimic the even heat distribution of an oven’s radiant walls. Work in small batches, usually 6 to 10 slices at a time depending on basket size, because stacking blocks airflow and produces uneven chips. For cinnamon-sugar or any sweet spice blend, cut the sugar by half, since concentrated air-fryer heat caramelizes coatings fast and scorched sugar tastes bitter.

A Modular Seasoning Matrix for Five Flavor Variations

One base recipe becomes five different flavors by changing only the dry seasoning on top of the oil. The ratios below are calibrated per bagel half (about 2 ounces of sliced bagel), so a tray of six halves uses roughly six times the amount listed.

Five Ready-to-Use Blends

• ▸Classic savory. 1 tbsp olive oil, ½ tsp garlic powder, ¼ tsp onion powder, and a pinch of kosher salt per bagel half.
• ▸Everything bagel. 1 tsp sesame seeds, 1 tsp poppy seeds, ½ tsp garlic powder, ½ tsp onion powder, and a pinch of salt.
• ▸Parmesan herb. 2 tbsp grated Parmesan, ½ tsp dried Italian seasoning, and a light oil brush; add the cheese in the last two minutes so it crisps instead of burns.
• ▸Cinnamon sugar. ½ tsp ground cinnamon, 1 tsp granulated sugar, and a barely-there oil coat to help the mix stick.
• ▸Build-your-own ratio. 1 part strong spice (cayenne, smoked paprika, cumin) to 2 parts supporting seasoning (garlic powder, dried herbs) to 4 parts salt, then adjust to taste.

The build-your-own ratio is the one to memorize. It keeps salt from dominating while letting a single bold spice carry the flavor. For a smoky chip, use cayenne as the strong spice; for a Mediterranean chip, swap in dried oregano or za’atar.

Oil Timing Matters for Cheese and Sugar

Parmesan and cinnamon-sugar both brown faster than salt-based seasonings. Brush the oil on first, bake for 10 minutes at the target temperature, then add the cheese or sugar and return the tray for the final 4 to 6 minutes. This two-stage seasoning prevents the topping from scorching while the bagel itself reaches the right dryness.

Seasonings are the fun part, but they mean nothing once the chips go soft by morning.

Troubleshooting Failures and Storing Chips for Lasting Crunch

Two failures account for most disappointing batches. The first is edges that brown before centers cook through, which usually means slices were too thick or the oven ran hot near the heating element. The second is chips that come out tough instead of crisp, which almost always traces back to too much oil weighing the slice down.

Common Failures and Their Fixes

• ▸Edges brown but centers stay doughy. Slice thinner next time (aim for 1/8 inch), lower the temperature by 25°F, and rotate the sheet pan 180 degrees at the halfway flip so the back edge gets the same exposure as the front.
• ▸Chips come out tough rather than crispy. Too much oil weighed them down. Brush a thinner coat, bake a few minutes longer at 325°F, and blot the slices on a paper towel the moment they leave the oven.
• ▸Chips soften overnight. Re-crisp at 300°F for 3 to 4 minutes on a dry sheet, or toss a folded paper towel into the storage container to absorb trapped moisture overnight.
• ▸Bottom of every chip burns. The baking sheet was too thin and conducted heat too fast. Switch to a heavy-duty aluminum sheet or stack two thin pans together to add insulation.

Storage That Actually Keeps Them Crunchy

Fully cooled chips last up to two weeks in a sealed glass jar at room temperature, as long as the jar is truly airtight and the chips were cool before going in (any residual warmth creates condensation). For longer storage, freeze them in a zip-top freezer bag with the air pressed out for up to two months; thaw at room temperature for 10 minutes or pop them straight into a 300°F oven for 3 minutes to restore the snap. Avoid plastic containers with loose-fitting lids, since they let in just enough humidity to soften the surface overnight.
