What You’ll Need (Ingredients)

Here’s a quick overview of what you’ll need for this dish (full details in the recipe card below):

• Sweet onions (Vidalia or yellow onions work best)
• Butter for that rich, savory flavor
• Parmesan and mozzarella cheese for the ultimate cheesy topping
• Heavy cream to bring everything together
• Ritz crackers or breadcrumbs for a buttery, crunchy topping
• A sprinkle of garlic powder, salt, and pepper for seasoning

How to Make It

Making Tennessee Onions is as straightforward as it gets, but the results are absolutely incredible. Here’s the step-by-step process:

1. Prep the onions: Slice your sweet onions into thick rings—about ½ inch thick—and spread them out in a buttered casserole dish.
2. Add the cream and seasoning: Pour a little heavy cream over the onions and season them with garlic powder, salt, and pepper.
3. Top with cheese: Sprinkle the onions generously with Parmesan and mozzarella cheese.
4. Add the buttery crunch: Crush some Ritz crackers or breadcrumbs, mix them with melted butter, and sprinkle the mixture on top of the cheese.
5. Bake until bubbly: Pop the dish in the oven and bake until the onions are tender, the cheese is melted, and the topping is golden brown.

Serve warm and watch everyone go back for seconds (and thirds!).

Pro Tips for the Best Tennessee Onions

• Choose the right onions: Sweet onions like Vidalia are ideal because they mellow and caramelize beautifully when baked. If you can’t find them, yellow onions work too.
• Slice evenly: Cutting the onions into even slices helps them cook uniformly.
• Go heavy on the cheese: Don’t skimp on the cheese—it’s what makes this dish so irresistible! Use freshly shredded cheese for the best melt.
• Customize the crunch: Ritz crackers are classic, but panko breadcrumbs work great too if you want an ultra-crispy topping.
• Make it your own: Add a sprinkle of fresh thyme, rosemary, or a pinch of red pepper flakes for extra flavor.

Make-Ahead Recipe Method

• Prep ahead: Slice the onions, arrange them in the casserole dish, and top with cream, seasoning, and cheese. Cover tightly and refrigerate for up to 24 hours.
• Add the topping later: Wait to add the buttery cracker topping until just before baking so it stays crispy.
• Bake straight from the fridge: You might need to add a few extra minutes to the baking time if the dish is cold.

Storage

• Fridge: Store leftovers in an airtight container for up to 3 days.
• Reheat: Warm them in the oven at 350°F until heated through. To bring back the crunch, pop them under the broiler for a minute or two.
• Freezer: This dish doesn’t freeze well due to the cream and cheese, so enjoy it fresh whenever possible.

Tools for This Recipe

• Casserole dish: A 9×13-inch dish works perfectly for this recipe.
• Sharp knife: For slicing the onions evenly.
• Mixing bowls: To mix the cracker topping.
• Cheese grater: Freshly grated cheese melts better and has more flavor.
