How to Make Tennessee Onions
Tennessee Onions shine because of their unpretentious appeal.
What makes Tennessee Onions stand out is their effortless charm. With just a few everyday ingredients, you can whip up a dish that tastes like you spent hours in the kitchen. All you need are:
- 2 large sweet onions (Vidalia or Walla Walla bring the perfect mild sweetness)
- 2 tablespoons of melted butter
- 1 cup of sharp cheddar, freshly grated
- ½ cup breadcrumbs
- Salt and black pepper to taste
No need for cream or flour-thickened sauces this dish proves that simple really can be sensational. Cut the onions into hearty ¼-inch slices and toss them in melted butter until every piece is glossy and well-coated. This step ensures the cheese melts into every layer and the topping sticks just right.
To bake, set your oven to 375°F (190°C) and lightly butter a casserole dish or line it with parchment for hassle-free cleanup. Arrange the onions flat or slightly overlapped to create a rich, cheesy middle. Season well.
Next, scatter the cheddar generously it’s the melty heart of the recipe. Finish with breadcrumbs (tossed in melted butter if you want extra crunch).
Bake for 20 to 25 minutes. When the cheese is bubbling and the top is a golden crisp, it’s ready. The smell alone will call your family to the table.

Tips, Storage, and Reheating
Top Tips for a Crispy, Cheesy Finish
Getting Tennessee Onions just right is easier than you think, but a few smart tips can make the difference between good and irresistible. First, always use sweet onions like Vidalia or Walla Walla. Their natural sugar helps balance the richness of the cheese and butter. Slice them thick enough to hold their shape during baking, about ¼ inch is perfect.
To keep your topping crispy, don’t skip the butter. Either toss the breadcrumbs in a bit of melted butter before layering, or drizzle a little over the top. It helps them brown evenly and stay crunchy. If you want extra flavor, add a touch of garlic powder, cayenne, or even dried herbs to the crumb mix.
Don’t overbake. Keep an eye on the dish during the last five minutes of cooking. The cheese should be melted and bubbling, and the top golden but not too dark. If your oven runs hot, check it a bit early.
Storing, Freezing, and Reheating Without Soggy Breadcrumbs
Tennessee Onions taste best straight from the oven, but with a few easy steps, the leftovers can still be just as enjoyable. Store them in an airtight container in the fridge for up to three days. When reheating, use the oven at 350°F. Heat for about 10 to 15 minutes, uncovered. This helps revive the crispy top without turning it soggy. It’s best to skip the microwave, since it tends to soften the breadcrumbs and turn the cheese a bit rubbery.
If you want to freeze them, wrap portions tightly in foil or a freezer-safe container. They’ll keep for up to two months. Let them defrost in the refrigerator overnight, then warm them up in the oven to bring back that fresh-baked texture.The texture won’t be exactly the same as fresh, but it will still be delicious and satisfying.
