Cheesy Tennessee Onions Hot and Flavorful Delight are the ultimate side dish when you want something cozy, a little bit decadent, and perfect for sharing with friends or family. The sweet Vidalia onions turn buttery soft in the oven, and all that gooey cheese takes them completely over the top. I love making these during cooler months when hearty, comforting dishes really shine on the table.
I first served these stuffed onions at a fall gathering, and now my friends always ask for the recipe when potluck season rolls around again. The way the cheese bubbles over the sweet onions always draws everyone to the table for seconds.
Ingredients
- Vidalia onions: These are extra sweet and become wonderfully tender when baked If you cannot find Vidalias look for other large sweet onions
- Sharp cheddar cheese: Gives a deep flavor and melts smoothly Freshly grating your cheese will give the best melt
- Cream cheese: Adds body and tang Use the full fat version for the richest filling
- Sour cream: Makes the filling creamy and smooth Opt for a thick style for best results
- Breadcrumbs: Make a crispy topping Look for panko for extra crunch or use fresh homemade crumbs
- Garlic powder: Boosts the savory flavor Look for a finely ground version for even mixing
- Onion powder: Adds extra oniony depth Even if it sounds redundant this makes the flavors pop
- Smoked paprika: Gives a touch of smokiness Use Spanish style smoked paprika for best results
- Cayenne pepper: For anyone who loves a little heat Add as much or as little as you like or skip for a milder version
- Salt and pepper: Essential for rounding out the flavors Taste and adjust as you mix
- Fresh chives: For color and a fresh finishing note Make sure they are bright green and snappy
Step-by-Step Instructions
- Prep the Onions:
- Carefully slice the tops off your Vidalia onions and use a spoon or small knife to scoop out the inside This leaves you with sturdy onion bowls about half an inch thick Save all the onion you pull out for the filling
- Make the Cheesy Filling:
- Combine softened cream cheese sour cream and half of the grated cheddar cheese in a medium bowl Mix until completely smooth and everything is evenly blended
- Flavor the Mixture:
- Finely chop the onion pulp you set aside Add to the creamy base along with garlic powder onion powder smoked paprika cayenne pepper salt and pepper Stir very well to distribute all the seasonings so every bite will be flavorful
- Stuff the Onions:
- Fill each hollowed out onion generously with the cheesy mixture Do not worry if it overflows a little the more filling the better
- Mix and Sprinkle Topping:
- In a clean bowl mix together the remaining grated cheddar cheese with breadcrumbs plus a pinch of salt and pepper Sprinkle this evenly over the stuffed onions forming a thick layer
- Bake Covered:
- Arrange your stuffed onions in a baking dish and cover it tightly with foil Bake at 375 degrees Fahrenheit for about 30 minutes This first bake helps steam the onions so they soften without drying out
- Finish Uncovered:
- Remove the foil and return the dish to the oven Bake for another 15 to 20 minutes until the topping is deeply golden and the onions are melt in your mouth tender Cheese should bubble and breadcrumbs get crunchy
- Cool and Serve:
- Let the onions stand for a few minutes after baking This helps the filling set so it is easier to serve Garnish each one with a sprinkle of chopped fresh chives for color and a fresh zippy flavor

One of my favorite things in this recipe is the sharp cheddar It cuts through the richness and really delivers that classic comfort food vibe I have memories of my kids helping sprinkle the breadcrumbs on top excited to see them come out all golden from the oven
Storage Tips
Leftover Cheesy Tennessee Onions will keep well covered in the fridge for up to three days and they are just as tasty reheated I recommend warming them gently in the oven to revive the crisp topping If you want to make ahead you can assemble everything except the topping then add the crumb layer just before baking
Ingredient Substitutions
If Vidalia onions are not in season try Walla Walla or any large yellow sweet variety Monterey jack or gouda both make great cheese swaps if you want something a little milder If you are avoiding gluten use gluten free breadcrumbs or crushed rice crackers in the topping
