Parmesan Onion Rings Ingredients For the Onion Rings • White Onions – Use medium-sized onions for uniform rings that cook evenly. • Shredded Parmesan Cheese – Freshly shredded creates the crispy coating that makes these onion rings shine. • Salt – Enhances flavor; adjust to your preference for the perfect taste. • Garlic Powder – Adds depth; powdered form blends easily into the mixture. • Paprika – Brings color and a hint of smokiness; feel free to omit if desired. • Italian Seasoning – Imparts a herbal note; swap with other mixed seasonings as you like. Dipping Sauce (Optional) • Keto Ranch Dressing – A creamy compliment that pairs perfectly with parmesan onion rings. • Spicy Mayo – A zesty option to add a kick to your dipping experience! Step‑by‑Step Instructions for Crispy Keto Parmesan Onion Rings Step 1: Preheat Oven Begin by preheating your oven to 400°F (200°C). While waiting for the oven to reach temperature, line a baking sheet with parchment paper. This prevents sticking and helps achieve that golden, crispy texture essential for these Parmesan Onion Rings. Step 2: Prepare Onions Peel the white onions and slice them into ¼-inch thick rings, ensuring they are uniform for even cooking. As you slice, place the rings on a clean surface. The consistent thickness will allow for that perfect crunch without any burnt edges when you bake your onion rings. Step 3: Form Cheese Base On the prepared baking sheet, place a tablespoon of shredded Parmesan cheese and shape it into a flat circle with about a 2-inch diameter. This cheese base will create a delightful crust around each onion ring. The cheese should look like a small disc, ready to embrace those onion rings. Step 4: Add Onion Rings Carefully place an onion slice on each cheese circle you’ve formed. Make sure that the onion slices sit snugly atop the cheese, allowing for maximum adhesion during baking. This step is crucial for achieving that crispy texture that makes these Parmesan Onion Rings irresistible. Step 5: Top with Cheese Sprinkle another tablespoon of shredded Parmesan cheese over each onion ring. Gently press down to ensure the cheese adheres well to the onion. This layer will melt and form a delightful, crispy shell as the rings bake, enhancing the flavor and texture of your Parmesan Onion Rings. Step 6: Season Season your creations by sprinkling salt, garlic powder, and paprika on top of the assembled onion rings to taste. These seasonings add a flavor punch that complements the cheesy goodness. Don’t hesitate to adjust the amounts to suit your personal preference for these delicious Keto Onion Rings. Step 7: Bake Transfer the baking sheet to the preheated oven and bake for 15-20 minutes. Keep a close watch on your Parmesan Onion Rings, looking for a golden-brown color to indicate they are done. Rotate the tray if necessary to ensure even cooking and prevent burning. Step 8: Cool Once baked to perfection, carefully remove the baking sheet from the oven and allow the onion rings to cool for 10-15 minutes. This cooling time is key to achieving maximum crispness, so resist the temptation to dive in right away. Enjoy the anticipation as you savor the aroma filling your kitchen.

Expert Tips for Crispy Parmesan Onion Rings Use Parchment Paper: To maximize crispiness, always line your baking sheet with parchment paper instead of foil, preventing sticking and promoting even browning. Uniform Thickness: Ensure your onion rings are sliced to the same thickness (¼-inch) for consistent cooking, avoiding chewy or burnt edges in your Parmesan Onion Rings. Watch the Cheese: Keep a close eye on the baking process; the cheese can quickly move from golden to burnt. Check frequently for that perfect crisp. Mix Your Cheeses: Experiment with different cheese varieties, like sharp cheddar or gouda, to elevate the flavor of your onion rings and delight your taste buds. Perfect Cooling Time: Allow your crispy onion rings to cool on the baking sheet for 10-15 minutes after baking. This step is essential for achieving that irresistible crunch! Make Ahead Options These Crispy Keto Parmesan Onion Rings are perfect for meal prep, allowing you to enjoy a delicious snack or side without the last-minute rush! You can slice the onions and form the cheese base up to 24 hours in advance. Just lay the prepared onion rings on the parchment paper, cover with plastic wrap, and refrigerate until you’re ready to bake. For the best quality, season right before baking to maintain flavor freshness. When you’re ready to indulge, simply add the final cheese topping and seasonings, then bake for 15-20 minutes until golden and crispy. This approach ensures restaurant-quality results with minimal effort, making your busy weeknights a breeze!
