Tennessee Onions – Creamy, Cheesy, and Better Than Onion Rings

Oh, friends… this one’s a keeper! I don’t say that lightly. You know how onion rings are everyone’s guilty pleasure at a summer BBQ? Well, imagine if they took a cozy trip to the South, got dressed in a rich, cheesy, buttery blanket, and came out of the oven golden, bubbling, and irresistible. That’s Tennessee Onions.

The first time I made these, my kitchen smelled like every good childhood memory rolled into one — buttery, toasty, and savory with that hint of sweet onion. I’m still kicking myself for not taking more photos because the bubbling cheese on top was a thing of beauty. And yes, I promised you versatile — here’s proof! These onions play well with grilled meats, roasted chicken, even as part of a holiday table.

What Do Tennessee Onions Taste Like?

Sweet onions turn tender and mellow in the oven, while a rich blend of cheddar, mozzarella, and Parmesan melts into a creamy, savory sauce. Butter soaks into every layer, and a hint of garlic, paprika, and thyme gives it depth. Think “French onion soup meets cheesy casserole” — only much easier to make.
