A creamy, cheesy, and savory casserole made with tender asparagus, a rich cheese sauce, and a crispy topping—perfect for a side dish or a comforting meal!

Ingredients

  • 1 lb fresh asparagus, trimmed and cut into 2-inch pieces
  • 1 cup shredded cheddar cheese
  • ½ cup grated Parmesan cheese
  • 1 cup heavy cream
  • 2 tablespoons butter
  • 1 tablespoon all-purpose flour
  • ½ teaspoon garlic powder
  • ¼ teaspoon onion powder
  • Salt and pepper to taste
  • 1 cup breadcrumbs (preferably panko for extra crunch)
  • 1 tablespoon olive oil (for topping)

Instructions

  • Preheat the Oven: Preheat your oven to 375°F (190°C) and lightly grease a 9×9-inch baking dish.
  • Blanch the Asparagus: Bring a pot of salted water to a boil. Add the asparagus pieces and cook for 2-3 minutes until slightly tender but still crisp. Drain and set aside.
  • Make the Cheese Sauce: In a large saucepan, melt the butter over medium heat. Stir in the flour and cook for 1-2 minutes to form a roux. Gradually add the heavy cream while stirring continuously to avoid lumps. Once smooth, cook for another 2-3 minutes until thickened. Add the garlic powder, onion powder, salt, and pepper. Remove from heat and stir in the cheddar and Parmesan cheeses until melted and smooth.
  • Combine Asparagus and Sauce: Add the blanched asparagus to the cheese sauce and stir to coat the asparagus evenly with the sauce.
  • Assemble the Casserole: Transfer the asparagus and cheese mixture into the prepared baking dish. Sprinkle breadcrumbs evenly over the top, and drizzle with olive oil to help the topping crisp up.
  • Bake: Bake in the preheated oven for 20-25 minutes, or until the top is golden brown and crispy.
  • Serve: Remove from the oven and let the casserole sit for a few minutes before serving.

Notes

  • You can use any cheese you like for the sauce, but sharp cheddar and Parmesan add great flavor.
  • For extra flavor, try adding a sprinkle of red pepper flakes or a squeeze of lemon juice before serving.
  • This casserole can be made ahead by assembling it and refrigerating until ready to bake.
