  • 2 cups shredded cheddar cheese

  • 1 cup sour cream

  • 1 cup milk

How to Make Cheesy Asparagus Casserole

Step-by-Step Instructions

  1. Preheat the oven to 350°F (175°C).

  2. Prepare the asparagus by trimming and cutting it into 1- to 2-inch pieces.

  3. Mix the sauce: In a large bowl, combine sour cream, milk, garlic powder, onion powder, salt, and pepper. Stir until smooth.

  4. Add the asparagus and cheese: Fold in the asparagus and half of the shredded cheese until everything is evenly coated.

  5. Transfer to a baking dish: Pour the mixture into a greased 9×13-inch dish and spread it evenly.

  6. Top it off: Sprinkle with the remaining cheese. Add breadcrumbs if you like a crunchy finish.

  7. Bake for 25–30 minutes, until the top is golden and bubbly.

  8. Let cool slightly and serve warm.

What to Serve With It

This casserole is a versatile side dish that pairs well with:

  • Grilled or roasted chicken

  • Baked salmon or white fish

  • Mashed potatoes for ultimate comfort

  • A crisp green salad for a fresh contrast

  • A glass of chilled white wine (like Chardonnay or Pinot Grigio)

Tips for Success

  • Use fresh asparagus for the best texture and flavor. Avoid frozen unless blanched and drained very well.

  • Try cheese variations like Gruyère, mozzarella, or a touch of parmesan for added depth.

  • Watch the bake time so the asparagus stays tender but not mushy.

  • Go easy on the liquid—the sauce should be creamy, not runny.

Storage & Reheating

To Store:
Place leftovers in an airtight container and refrigerate for up to 3 days.

To Reheat:
Warm in the oven at 350°F (175°C) for 10–15 minutes until heated through. Avoid microwaving if possible—it can make the topping soggy.

To Freeze:
You can freeze the fully baked (and cooled) casserole for up to 2 months. Thaw overnight in the fridge before reheating.


With its creamy texture, crisp-tender veggies, and gooey cheese, Cheesy Asparagus Casserole is a winning combination of flavor and comfort. Whether you serve it as a hearty side or a meatless main, it’s sure to become a favorite at your table.

So preheat that oven and get ready for some serious comfort food—this casserole won’t disappoint!
