  • 2 tablespoons unsalted butter
  • 2 tablespoons all-purpose flour
  • 1 cup whole milk
  • 1/2 cup sour cream

Instructions

  1. Preheat the oven: Preheat the oven to 375°F (190°C) and grease a 9×9-inch baking dish.
  2. Prepare asparagus: Steam or blanch asparagus until tender. Drain and set aside.
  3. Make cheese sauce: Melt butter, whisk in flour, then gradually add milk. Cook until thickened. Remove from heat and stir in sour cream, cheeses, garlic powder, onion powder, salt, and pepper.
  4. Combine ingredients: Add asparagus to cheese sauce, toss to coat, and pour into baking dish.

  6. Bake: Bake for 20–25 minutes until bubbly and golden brown. Let cool slightly before serving.

Notes

  • You can substitute Greek yogurt for the sour cream or use Gruyère for a more upscale flavor.
  • Add cooked bacon bits or caramelized onions for extra richness.
  • If using frozen asparagus, thaw and drain well before adding.
