These viral Parmesan onion rings from MyKetoPlate are a clever, low‑carb spin on a classic snack, using just onions and shredded Parmesan—no breadcrumbs or frying required. The cheese crisps into golden, lacy rounds that cling to each onion slice, delivering crispiness and savory depth as the onion caramelizes slightly in the oven. They're light yet addictive, perfect for keto followers or anyone craving a crunchy, flavorful nibble with minimal ingredients and effort. Expect bold taste, contrasting textures, and hands‑off simplicity—all baked to golden perfection.
2 medium white onions, peeled and sliced into ¼‑inch thick rings
2 cups freshly shredded Parmesan cheese (avoid pre‑grated types)
Seasonings: salt, garlic powder, paprika, and optional chili flakes or Italian seasoning to taste
Optional: light brush of olive oil for extra browning
Preheat oven to 400 °F (200 °C). Line a baking sheet with parchment paper (do not use foil or wax paper)
Slice onions evenly into ¼‑inch rings—use a mandoline for uniform cuts if available.
Spoon about 1 tablespoon of shredded Parmesan onto the parchment for each ring. Press into a flat circle slightly larger than the onion ring.
Place an onion ring on each cheese circle. Top each with another tablespoon of cheese, fully covering the onion; gently press down with the back of a spoon.
Season the tops with salt, garlic powder, paprika, and optional chili flakes or Italian seasoning. Brush a bit of olive oil if desired for deeper color.
Bake for 15–20 minutes, or until the cheese is deep golden brown and crispy around the edges. Watch carefully to avoid burning.
Cool on the baking sheet for 10–15 minutes—this allows rings to firm up and crisp fully before serving.
