Ingredients
- 4 pieces large onions
- 4 tablespoons unsalted butter
- 4 tablespoons all-purpose flour
- 2 cups whole milk
- 1.5 cups sharp cheddar cheese
- 1 teaspoon salt
- 0.5 teaspoons black pepper
- 0.25 teaspoons ground nutmeg
- 0.75 cups plain breadcrumbs
- 0.5 cups Parmesan cheese
- 1 tablespoon olive oil
Directions
Step 1
Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish and set it aside.
Step 2
Peel the onions and slice them into 1/4-inch thick rings. Separate the rings and set them aside.
Step 3
Bring a large pot of water to a boil. Add the onion rings and blanch them for 3 minutes, then drain and set aside.
Step 4
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes to form a roux, stirring constantly to avoid browning.
Step 5
Gradually whisk in the milk until smooth. Continue cooking and whisking for 5-7 minutes, or until the sauce thickens.
Step 6
Stir in the cheddar cheese, salt, black pepper, and nutmeg, whisking until the cheese is fully melted and the sauce is smooth.
Step 7
Layer half of the blanched onions in the prepared baking dish. Pour half of the cheese sauce over the onions. Repeat with the remaining onions and cheese sauce, ensuring the onions are fully coated.
Step 8
In a small bowl, combine the breadcrumbs, Parmesan cheese, and olive oil until evenly mixed. Sprinkle the mixture evenly over the top of the dish.
Step 9
Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and bubbling.
Step 10
Let the dish cool for 5 minutes before serving. Enjoy Momma's Scalloped Onions as an irresistible side dish!
