INSTRUCTIONS

1. Spray a 10x10-inch baking dish with oil and set aside.

3. When the oil is hot, add red onion and sauté until softened.
4. Stir in heavy cream, milk, garlic powder, onion powder, and fresh thyme, whisking well to combine.
5. Once the mixture simmers, whisk in the flour and bring to a boil, continuing to whisk.
