1. Prep the Asparagus
-
Preheat oven to 375°F (190°C). Grease a 2-quart baking dish (8×8-inch or similar).
-
Fresh asparagus: Blanch in boiling water 2–3 minutes, then drain.
-
Frozen asparagus: Thaw, drain, and pat dry.
-
Spread asparagus evenly in the prepared baking dish.
2. Make the Cheese Sauce
-
Melt 2 tbsp butter in a saucepan over medium heat.
-
Whisk in flour and cook 1–2 minutes until bubbly (this is your roux).
-
Gradually whisk in warmed milk and cook 2–3 minutes until thickened.
-
Reduce heat to low, stir in cheddar until melted.
-
Remove from heat and stir in sour cream, garlic powder, onion powder, nutmeg, salt, and pepper.
3. Assemble the Casserole
-
Pour cheese sauce over the asparagus and gently toss to coat.
-
In a small bowl, mix panko, melted butter, and Parmesan. Sprinkle evenly over the top.
-
Optional: Add a pinch of paprika for a pop of color.
4. Bake to Golden Perfection
-
Bake uncovered for 20–25 minutes, until bubbly and the topping is golden brown.
-
Let rest 5 minutes before serving—the sauce will thicken slightly.

Make-Ahead & Storage Tips
-
Make-ahead: Assemble (unbaked), cover, and refrigerate up to 24 hours. Add 5–10 minutes to baking time.
-
Leftovers: Store in the fridge up to 3 days. Reheat in the oven at 350°F for best texture.
-
Freezing: Not recommended—asparagus softens when thawed.
FAQs
Q: Can I use gluten-free flour?
A: Yes! Use a 1:1 gluten-free blend (like Bob’s Red Mill) for the roux.
Q: No sour cream?
A: Substitute with plain Greek yogurt or omit entirely—the sauce will be slightly less rich but still delicious.
Q: Can I add other veggies?
A: Absolutely! Sautéed mushrooms, peas, or diced carrots mix beautifully with asparagus.
Q: Can I make this for Thanksgiving ahead of time?
A: Definitely! Assemble the night before and bake while the turkey rests.
