Alfredo Asparagus Is the “Most Delicious” Side Dish You’ll Make All Spring

Melt 1 tablespoon unsalted butter in a small skillet over medium heat. Add the garlic and cook until fragrant, 30 seconds to 1 minute. Sprinkle in 1 tablespoon all-purpose flour and whisk for 30 seconds to 1 minute to cook the floury taste out. While whisking constantly, slowly pour in 1 cup whole or 2% milk. Continue whisking occasionally until smooth and simmering. Cook, stirring constantly, until the sauce is slightly reduced and thickened enough to coat the back of a spoon, 2 to 3 minutes.
