Heat the Olive Oil: In a medium skillet, heat 2 tablespoons of olive oil over medium-high heat until it shimmers, about 2 minutes.

Sauté the Garlic: Add 3 cloves of minced garlic to the hot oil, stirring frequently for about 2-3 minutes until golden but not brown.

Incorporate the Flour and Seasonings: Sprinkle in 2 tablespoons of flour, 1 teaspoon of dried oregano, ground black pepper, and salt to taste. Stir for 1-2 minutes.

Add the Half & Half: Gradually whisk in 1 cup of half & half, mixing continuously to prevent lumps until the sauce becomes creamy.

Thicken the Sauce: Continue cooking while stirring for another 3-4 minutes or until the sauce thickens to a smooth custard consistency.

Serve or Store the Sauce: Remove from heat and allow to cool slightly before serving or store in an airtight container in the refrigerator.
