1-First Steps and Cooking Basics: Melt the 4 tablespoons of salted butter in a large skillet over medium heat. Add the 1 teaspoon of minced garlic (or 4 grated garlic cloves) and cook for 30 seconds, stirring constantly to keep it from burning. This quick step brings out the garlic’s fresh flavor without any harshness.

2-First Steps and Cooking Basics: Stir in the 2 tablespoons of all-purpose flour and cook for about 1 minute until it’s lightly browned, making sure to stir frequently. Gradually whisk in the 2 cups of half and half, then add salt and pepper to taste for seasoning.

3-Simmering and Finishing Touches: Simmer the mixture while stirring occasionally until it thickens, which takes about 1 to 2 minutes, and check that no lumps remain for a silky result. Remove from heat and mix in the ⅓ cup of freshly grated Parmesan cheese and the 2 tablespoons of fresh parsley (or 2 teaspoons dried parsley). Serve it right away to enjoy the best texture, as it thickens more once cooled.
