Baked Asparagus Casserole Ingredients

• 2 pounds fresh asparagus, trimmed
• 4 tablespoons butter

How to Make Baked Asparagus Casserole

1. Preheat your oven to 400°F. Grab a 13×9-inch baking dish and arrange the trimmed asparagus in an even layer.
2. In a medium saucepan, melt the butter over medium heat. Whisk in the flour, garlic powder, salt, and pepper to create a roux. Cook for 1 minute.
3. Gradually whisk in the half-and-half. Keep stirring as the sauce thickens, about 3-4 minutes. Remove from heat and stir in the Parmesan cheese until melted.
4. Pour the creamy Parmesan sauce evenly over the asparagus.
5. In a small bowl, combine the melted butter, crushed Ritz crackers, and additional Parmesan cheese. Sprinkle this mixture on top of the sauce-covered asparagus.
6. Cover the baking dish with foil and bake for 10-15 minutes. Then, uncover and bake for another 10-15 minutes until the asparagus is fork-tender and the topping is golden brown.

Jake’s Tips for the Best Baked Asparagus Casserole

• Trim asparagus quickly: Line up the stalks and cut all at once rather than one by one. Saves so much time!
• Make ahead: Assemble the casserole up to a day in advance. Cover and refrigerate, then bake just before serving.
• Double the topping: Love extra crunch? Simply up the Ritz cracker mixture for an even thicker crust.
• Reheat like a pro: Warm leftovers at 350°F for 10-15 minutes. It’ll taste just like fresh-baked!
• Avoid overcooking: Check your asparagus at the 20-minute mark to prevent it from getting mushy.

Easy Baked Asparagus Casserole Variations

• Add bacon: Sprinkle cooked, crumbled bacon over the topping for extra flavor.
• Cheddar swap: Replace Parmesan with sharp cheddar for a totally different vibe.
• Vegetarian mix: Toss in mushrooms or spinach for a heartier vegetable casserole with asparagus.
• Spicy kick: Mix in a pinch of red pepper flakes with the cream sauce for a subtle heat.
