Step‑by‑Step Instructions for Viral Parmesan Onion Rings
Step 1: Preheat the Oven
Start by preheating your oven to 400°F (200°C). This is the perfect temperature for the Viral Parmesan Onion Rings to crisp up beautifully. While the oven heats, line a baking sheet with parchment paper to promote optimal crispiness and prevent sticking.
Step 2: Prepare the Onions
Peel and slice two medium white onions into ¼-inch thick rings. A mandoline slicer works wonders in achieving uniformity for even cooking. As you prepare the onions, admire their lovely layers; each ring will be a crispy vessel for your delicious cheese coating!
Step 3: Create Cheese Molds
On the parchment-lined baking sheet, place a tablespoon of shredded parmesan cheese, forming a small circle slightly larger than the onion ring. These cheese circles will act as the base for your Viral Parmesan Onion Rings. The goal is to create a crispy layer that encases the onion and contributes to that mouthwatering crunch.
Step 4: Assemble the Rings
Carefully position an onion slice on top of each cheese circle you’ve created. Add another tablespoon of shredded parmesan cheese on top of each onion ring, gently pressing to ensure the cheese adheres well. This double-layer of cheese will provide an extra layer of crunch and flavor when baked.
Step 5: Season to Taste
Sprinkle salt, garlic powder, and paprika over the tops of the assembled rings to your liking. This step elevates the flavors of your Viral Parmesan Onion Rings, so feel free to adjust the seasonings to suit your palate. The combination of seasonings will add a delightful depth to each bite.
Step 6: Bake in the Oven
Carefully place the baking sheet in the preheated oven and bake for 15-20 minutes. Keep an eye on the rings, watching as they transform into golden perfection. The cheese should turn deep golden and crispy—this visual cue is critical for ensuring the best texture and flavor.
Step 7: Cool Before Serving
Once baked to perfection, remove the Viral Parmesan Onion Rings from the oven and allow them to cool on the baking sheet for 10-15 minutes. This essential cooling time allows the rings to firm up, achieving maximum crispiness before you indulge in their cheesy goodness.

Make Ahead Options
These Viral Parmesan Onion Rings are perfect for meal prep enthusiasts looking to save time during busy weeknights! You can slice and prepare the onions up to 24 hours in advance; simply store the rings in an airtight container in the refrigerator to keep them fresh. Additionally, you can pre-assemble the cheese molds and store them separately; this method ensures the cheese stays crisp until you’re ready to bake. When it’s time to cook, just position the onion slices on the cheese circles, season to taste, and bake as directed, resulting in deliciously crispy rings that are just as irresistible even when made ahead!
