I can't stop thinking about this dish, it's too amazing not to mention.

Preheat your oven to 350°F (175°C).
Lightly grease a 9x13 inch baking dish.
Blanch the asparagus in boiling water for 2-3 minutes, then drain and set aside.
In a large bowl, mix together the cream of mushroom soup, milk, cheddar cheese, garlic powder, and black pepper.
Add the blanched asparagus to the soup mixture and stir until well coated.
Pour the asparagus mixture into the prepared baking dish.
Sprinkle the French fried onions evenly over the top.
Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and the onions are golden brown.
Let it cool for a few minutes before serving.
Variations & Tips
For a little extra flavor, try adding cooked bacon bits or diced ham to the casserole. If you have picky eaters, you can substitute the asparagus with broccoli or green beans. For a spicier kick, mix in a pinch of red pepper flakes or a dash of hot sauce. If you're looking for a vegetarian option, use cream of celery soup instead of cream of mushroom.
