Creamy Cheesy Asparagus Casserole

Step 2: Blanch the Asparagus

Bring a medium pot of salted water to a boil. Add the asparagus pieces and cook for 2–3 minutes until bright green and slightly tender. Drain and immediately transfer them to a bowl of ice water to stop the cooking process. Drain again and set aside. This step keeps the asparagus crisp-tender and vibrant.

Step 3: Make the Creamy Cheese Sauce

1. In a medium saucepan, melt the butter over medium heat.
2. Stir in the flour and cook for 1–2 minutes to form a smooth roux.
3. Gradually whisk in the milk (and cream, if using) to prevent lumps. Continue whisking until the mixture thickens slightly, about 3–5 minutes.
4. Add Dijon mustard, salt, pepper, and garlic powder. Taste and adjust seasoning.
5. Remove from heat and stir in ¾ cup of cheddar cheese and half of the Parmesan cheese until fully melted and smooth.

Step 4: Assemble the Casserole

• Place the blanched asparagus into the prepared baking dish.
• Pour the creamy cheese sauce over the asparagus, ensuring even coverage.
• Sprinkle the remaining cheddar and Parmesan cheese on top.
• If using, mix the breadcrumbs with olive oil or melted butter and sprinkle evenly over the cheese for a crunchy topping.

Step 5: Bake to Golden Perfection

Bake in the preheated oven for 20–25 minutes, or until the casserole is bubbly and the top is golden brown. If you prefer a crispier topping, place it under the broiler for 1–2 minutes at the end, watching carefully to prevent burning.

Step 6: Serve and Enjoy

Allow the casserole to cool for a few minutes before serving. This dish pairs beautifully with roasted meats, grilled chicken, or can be enjoyed as a comforting vegetarian main course.

Tips for the Best Casserole

• Fresh asparagus makes all the difference; choose firm, bright green stalks.
• Cheese varieties: Try mixing cheddar with Gruyère or Fontina for a deeper flavor.
• Make-ahead: You can assemble the casserole up to a day in advance and refrigerate. Bake just before serving.
• Add-ons: Sautéed mushrooms or caramelized onions can elevate the flavor profile.
