how to make Baked Parmesan Onion Rings (Keto-Friendly & Ultra-Crispy)
This method uses only shredded Parmesan pressed into thin rounds, then baked with the onion rings inside. Work on a piece of parchment so the cheese can spread and crisp. Let the rings cool well on the tray to harden and get extra crunch.
Ingredients :
- 2 medium white onions, sliced into ¼‑inch thick rings
- 2 cups shredded Parmesan cheese
- Salt, to taste
- Garlic powder, to taste
- Paprika, to taste
- Optional: Italian seasoning, to taste
- Optional: Olive oil, for brushing
Directions :
- Preheat oven to 400 °F (200 °C) and line a baking sheet with parchment paper.
- Peel and slice onions into ¼‑inch thick rounds.
- For each ring, place about 1 tablespoon of shredded Parmesan onto the parchment and press into a flat circle slightly wider than the onion.
- Place an onion ring on each Parmesan circle.
- Top each ring with another tablespoon of Parmesan; press gently with a spoon to adhere.
- Season each with salt, garlic powder, and paprika (and Italian seasoning if using).
- Optionally brush with a little olive oil for extra browning.
- Bake 15–20 minutes, until cheese is deep golden brown and crispy.
- Let cool on the baking sheet for 10–15 minutes before serving to maximize crunch.
how to serve Baked Parmesan Onion Rings (Keto-Friendly & Ultra-Crispy)

how to store Baked Parmesan Onion Rings (Keto-Friendly & Ultra-Crispy)

tips to make Baked Parmesan Onion Rings (Keto-Friendly & Ultra-Crispy)
- Use finely shredded Parmesan for an even melt and crisp.
- Press the cheese thin and slightly wider than the ring so edges crisp well.
- Do not overcrowd the baking sheet; give each ring space.
- Cool fully on the tray so the cheese sets hard.
- If onions release a lot of moisture, pat them dry before assembling.
variation (if any)

- Add a pinch of cayenne for heat.
- Make mini rings from small pearl onions for bite-size snacks.
- Add crushed herbs like rosemary or thyme for a savory twist.
FAQs
Q: Can I use other cheeses?
A: Yes. Hard cheeses that melt and crisp work best, like cheddar or pecorino. Softer cheeses may not crisp as well.
Q: Will the rings stick to the parchment?
A: Good parchment prevents sticking. Let rings cool fully before lifting; they release easier when set.
Q: Can I make these ahead?
A: You can bake and cool them, but they are best the same day. Recrisp briefly in a hot oven before serving.
Q: Are these gluten free?
A: Yes. They have no flour or breadcrumbs.
Q: How do I keep them from burning?
A: Watch the last few minutes of baking. If edges brown too fast, lower oven to 375 °F and bake a bit longer.
