How to Make Southern 4-Ingredient Sweet Onion Squares

Ingredients

1 sleeve buttery round crackers, crushed
1/2 cup unsalted butter, melted
2 large sweet onions, thinly sliced
2 cups shredded cheddar cheese

Directions

Preheat the oven to 350°F and line an 8-inch square baking pan or small rimmed baking tray with foil for easy cleanup.
In a bowl, stir the crushed crackers with the melted butter until the crumbs are evenly coated, then press the mixture firmly into the bottom of the prepared pan to form the crust.
Spread the sliced sweet onions evenly over the crust, separating the slices a bit so they bake up tender and sweet.
Sprinkle the shredded cheddar cheese all over the onions, covering the top from edge to edge.
Bake for 30 to 35 minutes, until the onions are soft, the cheese is melted and bubbling, and the edges are deeply golden brown.
Let the pan cool for 10 to 15 minutes, then lift out with the foil, cut into squares, and serve warm.
