How to Make Keto Viral Onion Ring Pizza Recipe
Step 1: Preheat & Prep
Start by revving your oven up to a toasty 400°F (200°C). Lay down a sheet of parchment paper on your baking tray and give it a quick spritz with olive oil spray. This little prep step helps to keep everything from sticking while ensuring the onion rings crisp up beautifully during baking.
Step 2: Arrange the Base
Take your sliced onion rings and carefully lay them flat on the prepared baking tray. Make sure they’re spread out without overlapping, so each ring has enough room to become perfectly crispy and slightly caramelized in the oven.
Step 3: Cheese It Up
Now comes the best part: sprinkling the shredded mozzarella and parmesan evenly over and around the onion rings. The cheese doesn’t just make it delicious, it also acts like a glue to hold the rings together. Next, dust your pizza with garlic powder and Italian seasoning to amp up those mouthwatering flavors.
Step 4: Add Toppings
Here’s where you make it truly your own! Layer on keto-friendly toppings like spicy pepperoni slices, fiery jalapeños, or briny olives—anything that excites your pizza cravings while keeping it low-carb. Don’t be shy with your choices. This step is pure fun.
Step 5: Bake to Perfection
Pop your creation into the oven and let it bake for 12 to 15 minutes, or until the cheese bubbles up in golden perfection. Once baked, allow it to cool for a few minutes—this helps everything set so that when you slice and serve, each piece holds together beautifully.
How to Serve Keto Viral Onion Ring Pizza Recipe

Garnishes
To elevate your onion ring pizza even more, sprinkle freshly chopped basil or a handful of chopped green onions just before serving. A drizzle of high-quality extra virgin olive oil or a pinch of crushed red pepper flakes can add that extra oomph, highlighting the rich cheesy goodness.
Side Dishes
This cheesy, crispy pizza shines on its own, but pairing it with a simple green salad drizzled with lemon vinaigrette or a creamy avocado dip can create a well-rounded, keto-friendly meal that won’t weigh you down.
Creative Ways to Present
For a party or casual get-together, try serving the Keto Viral Onion Ring Pizza Recipe in bite-sized squares or wedges on a large wooden board surrounded by bowls of dipping sauces like garlic aioli or spicy marinara. The unique onion base is always a conversation starter, making presentation a fun way to impress your friends and family.
Make Ahead and Storage
Storing Leftovers
Leftover slices can be stored in an airtight container in the refrigerator for up to 3 days. To keep the crispiness, separate layers with parchment paper so they don’t stick together or get soggy.
Freezing
If you want to prepare this dish ahead of time or save leftovers for later, freezing is an option. Place slices on a baking sheet lined with parchment to freeze individually, then transfer to a freezer-safe bag. They’ll keep well for up to 1 month.
Reheating
When ready to enjoy again, reheat slices in a preheated oven at 350°F (175°C) for about 8-10 minutes to revive that crispy texture. Avoid microwaving if possible, as it can make the onion rings soggy and take away the delightful crunch.
FAQs
Can I use other types of cheese instead of mozzarella and parmesan?
Absolutely! While mozzarella and parmesan offer the best melt and flavor combination, feel free to experiment with cheddar, gouda, or even pepper jack for a smoky or spicy twist. Just make sure your cheese melts well.
Are all onion varieties good for this recipe?
Sweet onions like Vidalia or Walla Walla work wonderfully because they caramelize well and add a natural sweetness. However, Yellow or White onions can also be used if that’s what you have on hand.
Can I make this recipe vegan or dairy-free?
You can adapt it by using dairy-free cheese alternatives that melt well and skipping the parmesan or replacing it with nutritional yeast for a cheesy flavor. Keep in mind, texture may vary slightly.
What keto-friendly toppings do you recommend?
Popular options include pepperoni, cooked sausage, olives, jalapeños, spinach, mushrooms, and bell peppers. Just be mindful of carb content and avoid sugary or starchy toppings.
Is this recipe suitable for meal prep?
Definitely! The Keto Viral Onion Ring Pizza Recipe stores and reheats well, making it an excellent choice for batch cooking or quick keto meals throughout the week.
