1. Peel the onions and slice them into thick rings. Separate the layers to create rings, and set aside.
2. In a medium bowl, combine the cream cheese, cheddar cheese, and chopped jalapeños. Mix until well combined.
3. Fill each onion ring with the jalapeño and cheese mixture. Press gently to ensure the filling stays in place.
4. Set up a breading station with three bowls: one with flour seasoned with salt and pepper, one with beaten eggs, and one with panko breadcrumbs mixed with garlic powder and smoked paprika.
5. Dip each stuffed onion ring into the flour, then egg, and finally coat with the panko mixture. Press to ensure even coverage.
6. Heat vegetable oil in a large skillet over medium-high heat. Once hot, carefully fry the onion rings in batches until golden brown and crispy, about 3-4 minutes per side.
7. Remove from oil and drain on paper towels. Serve hot and enjoy!

Pro tip from my kitchen: Use a fork to gently press the breadcrumb coating onto each ring for an extra crunchy texture.
