📝 Preparation Steps
1
Preheat the oven to 375°F. Butter a 2-quart baking dish.
2
In a medium bowl, combine half the crushed crackers with half the parmesan. In a large nonstick skillet, melt 2 tablespoons of the butter over medium heat. Pour the melted butter over the cracker mixture and stir to combine. Reserve for the topping. Do not wipe out the skillet.
3
In the same skillet, melt the remaining 4 tablespoons butter over medium heat. Add the onions, pepper, and 1 teaspoon of the salt, and cook, stirring frequently, until softened and translucent (do not let the onions start to brown), 10 to ⏱️ 12 minutes. Transfer the onions to a large bowl and let cool for ⏱️ 5 minutes.
4
In a large measuring cup, whisk together the heavy cream, eggs, and remaining 1 teaspoon salt. Add the egg mixture to the onions, along with 1 ½ cups of the cheddar cheese, the remaining crushed crackers, and the remaining parmesan. Toss to combine. Spoon the mixture into the prepared baking dish and top with the remaining ½ cup cheddar cheese and reserved cracker mixture.
