Ingredients for Baked Creamed Onions

  • Frozen Pearl Onions
  • 2 tablespoons butter (for onions) + 1/4 cup (1/2 stick) butter (for sauce)
  • 1/4 cup all-purpose flour
  • Heavy Cream
  • Pecorino Romano Cheese
  • Salt
  • Nutmeg
  • Cayenne
  • 1 cup breadcrumbs

How to Make Baked Creamed Onions

  1. Preheat oven to 350°F (175°C).
  2. Peel and thinly slice one 2 lb bag of yellow onions. In a large skillet, cook onions over medium heat with 2 tablespoons of butter and 1 teaspoon of salt for 15-20 minutes, or until softened and lightly caramelized, stirring occasionally. Drain off any excess liquid.
  3. In a medium saucepan, melt 1/4 cup (1/2 stick) butter. Whisk in 1/4 cup all-purpose flour and cook for 3-4 minutes, stirring constantly, until a smooth roux forms. Gradually whisk in 1 cup heavy cream, then add 1 cup shredded cheddar cheese, 1/4 teaspoon cayenne pepper, and 1/4 teaspoon black pepper. Simmer for 5-7 minutes, or until the sauce has thickened to your desired consistency.
  4. Gently fold the creamed sauce into the cooked onions. Pour the mixture into a greased 9x13 inch baking dish. Top with 1 cup breadcrumbs. Bake for 15-20 minutes, or until bubbly and golden brown.

Chef's Tip for Extra Flavor

Want to unlock deeper, more complex flavors? Try toasting your whole spices before grinding them, or blooming ground spices in a little warm oil to enhance their aroma. Deglazing your pan with a bit of stock, wine, or even water after browning ingredients can capture those tasty caramelized bits, adding richness to your dish.
