Notes on the nutrition estimate:

• The calorie and macronutrient totals were derived primarily from ingredient values in USDA FoodData Central (Parmesan, onions, avocado oil, common spices). Sodium is likely to be the most variable value depending on the Parmesan brand and how much salt you choose to use—if you’re watching sodium, reduce or omit added salt. For general sodium guidance, the CDC recommends keeping daily sodium intake below 2,300 mg for most adults.

Perfect For…

• Low-carb & keto-friendly snacking: With roughly 6 g net carbs per serving, these are one of the tastiest ways to satisfy crunch cravings while staying under carb goals.
• Parties & game day: They crisp up in large batches and look great on a charcuterie board.
• Quick comfort food: Warm, salty, and comforting for cozy evenings.
• Flavor-forward snacking: If you love bold, cheesy flavors, these deliver with minimal effort.

How to Make Crispy Viral Onion Ring Chips: The Best Keto Snack Ever

Ingredients

• 1 cup Parmesan cheese, freshly grated (about 100 g)
• 2 medium yellow onions, sliced thinly (about 220 g total)
• 2 tablespoons avocado oil (can substitute with olive oil)
• 1 teaspoon paprika (adjust to taste)
• 1 teaspoon coarse sea salt (reduce if mindful of sodium)
• 1 teaspoon garlic powder (or substitute with onion powder)
• 1 teaspoon seasoning salt (homemade or store-bought)
• 1/2 teaspoon ground black pepper (adjust based on palate)

Optional ingredients and substitutions

• Use Pecorino Romano instead of Parmesan for a sharper flavor (raises sodium).
• For dairy-free/vegan: substitute with 1 cup crushed pork rinds or a mix of almond flour and nutritional yeast (see Variations).
• Use olive oil if you don’t have avocado oil (similar smoke point if not cooking at very high heat).
• Add a pinch of cayenne or smoked paprika for heat and a smoky note.

Step-by-step Instructions

1. Preheat oven to 400°F (205°C) if baking. If using an air fryer, preheat to 375°F (190°C).
2. Line a baking sheet with parchment paper or lightly grease an air fryer basket to prevent sticking.
3. In a mixing bowl, toss the thinly sliced onions gently with avocado oil until evenly coated.
4. In a separate bowl, combine the grated Parmesan, paprika, garlic powder, seasoning salt, coarse sea salt, and black pepper. Mix well so spices are distributed.
5. Working in small batches, press onion slices into the Parmesan-spice mixture — you want each slice to have a good, even coating. For an even crunch, press both sides lightly so the cheese adheres.
6. Arrange coated onion rings in a single layer on the prepared baking sheet or in the air fryer basket. Avoid overlapping; overcrowding causes steaming instead of crisping.
7. Bake for 20–25 minutes, flipping once halfway through, until golden brown and very crisp. In an air fryer, cook 10–15 minutes, checking at 10 minutes and shaking the basket to ensure even browning.
8. Remove and let rest on a cooling rack or paper towel for 5 minutes — they crisp further as they cool.
9. Serve warm or at room temperature.

Practical tips

• Slice onions consistently thin (use a mandoline if you have one) so chips cook evenly.
• Don’t skimp on pressing the Parmesan onto the slices; a good coating is the key to crisp texture.
• If chips are soft after baking, return them to the oven for a few more minutes on a lower rack to dry out.
• Cool on a rack rather than a plate — trapped steam will soften them.

Best Pairings

• Dips: Serve with a creamy herb dip (sour cream + chives) or a spicy garlic aioli.
• Drinks: Pairs beautifully with a dry white wine or a citrusy cocktail; also works with coffee for a savory breakfast snack.
• Boards: Add to a cheese board with cured meats, olives, and pickles for textural contrast.
• Toppings: A light brush of melted butter and a sprinkle of fresh parsley or lemon zest brightens the flavor.

Keeping it Fresh

• Room temperature: Store in an airtight container at room temperature for up to 2 days; keep away from humid areas.
• Refrigeration: Because these are best crisp, refrigeration isn’t recommended for storage — it tends to make them soften. If you must refrigerate due to toppings or dairy-based dips, store in an airtight container for up to 3 days and re-crisp in the oven before serving.
• Freezer: Not recommended — freezing will ruin the crisp texture.

Insider Secrets

• Use freshly grated Parmesan (not pre-grated) — it melts and browns better and gives superior crisping.
• For ultra-light crispness, pop baked chips under the broiler for 30–60 seconds at the end, watching constantly to avoid burning.
• If you want uniformly thin rings, slice onions across the equator and separate layers carefully — the outer layers make larger chips while inner layers yield smaller, delicate crisps.
• Adjust salt carefully: Parmesan contributes substantial sodium; taste before adding extra coarse salt.

Creative Twists

• Vegan/Gluten-free: Replace Parmesan with 3/4 cup crushed pork rinds (for carnivore-friendly) or 3/4 cup almond flour + 3 tbsp nutritional yeast for a vegan/low-carb cheese-like coating.
• Spicy Buffalo: Add 1/2 teaspoon cayenne and serve with blue-cheese or ranch-style dip for a buffalo-inspired chip.
• Herby Lemon: Mix 1 tsp dried oregano and 1 tsp lemon zest into the Parmesan for a Mediterranean twist.
• Smoky BBQ: Replace paprika with smoked paprika and add 1 tsp brown sugar substitute (erythritol) for a keto-friendly smoky bite.

All Your Questions Answered

Q: Can I make these without Parmesan?
A: Yes — see the Vegan/Gluten-free variation (almond flour + nutritional yeast) or crushed pork rinds for a low-carb, zero-dairy option.

Q: My chips are soggy — what went wrong?
A: Likely overcrowding or slices were too thick. Bake in a single layer and make sure slices are thin and evenly coated. Finish in the broiler briefly if needed.

Q: Are these actually keto-friendly?
A: Yes — at roughly 6 g net carbs per serving, they fit low-carb and many keto plans, but track your portion sizes. Nutritional values vary by ingredients and brands.

Q: How can I reduce sodium?
A: Use a low-sodium Parmesan or rinse and pat-dry pre-shredded alternatives, reduce or omit the added coarse/seasoning salt, and use herbs and spices for flavor instead.

Q: Can I make these ahead for a party?
A: You can bake ahead and re-crisp in a 325°F oven for 4–6 minutes before serving. Store in an airtight container to limit moisture exposure.
