Asparagus Casserole Recipe:
Spring is in the air which means asparagus is plentiful in grocery stores! Read on to learn how to select the best quality fresh asparagus for this casserole.
This is a holiday worthy asparagus casserole (think Easter!) and comes together quickly. Watch everyone’s eyes light up when they see you pull this beauty out of the oven. This asparagus bake is irresistibly good served with creamy mashed potatoes and beef tenderloin or prime rib.

Is Asparagus Better Thick or Thin?
Thin Asparagus generally come from a younger asparagus crown (root bed). Skinny asparagus cooks faster so it’s a great option for stir frying.
Thick asparagus comes from an older asparagus crown. Since it takes longer to cook, it tends to be better for high heat cooking (broiling and roasting).
Ultimately, size is not important. Both thin and thick asparagus will work in this recipe. They taste the same and are equally sweet and tender. Be sure to adjust the timing as skinny asparagus will bake faster and big asparagus spears will take longer to reach desired tenderness.

How to Select Asparagus:
Size doesn’t matter when it comes to selecting asparagus, but freshness is importance. The signs of freshly pickled asparagus are:
- Tops that are tightly closed (not open or fraying)
- Bottoms that look moist and plump (not too dry or shriveled)
How to Trim Asparagus:
There are several methods for trimming asparagus. You can either peel the ends with a potato peeler or snap off the ends. For two pounds of asparagus, the easiest way (our preferred method), is to snap off the ends. Hold the bottom third of the spear with both hands and bend. It will naturally snap where the fibrous portion ends and the tender part begins.

Is Asparagus Healthy to Eat?
Asparagus is impressively good for you! It is known for its high folic acid, potassium, fiber, thiamine, B Vitamins, Vitamin A, Vitamin C and Vitamin K content. Adding to the list of asparagus health benefits, it also has anti-inflammatory and antioxidant properties.*
How to Make Asparagus Casserole:
- Butter a 9×13 casserole and arrange trimmed asparagus, packing it so the surface is level.
- Make the Sauce: melt 3 Tbsp butter in a saucepan and add 2 1/2 Tbsp flour, whisking until golden. Add 2 cups half and half, 2 tsp garlic salt and 1/4 tsp pepper and whisk until starting to thicken. Remove from heat and stir in 1/2 cup parmesan.
- Pour sauce over casserole and bake at 400˚F for 15-18 min.
- Meanwhile, make the topping: stir together 1 Tbsp melted butter with 1/2 cup bread crumbs then stir in 1/2 cup parmesan. Halfway through baking, sprinkle on the topping.
- Broil 2-3 minutes at the end until topping is crisp and golden.

Asparagus Casserole

Ingredients
- 2 lbs asparagus, trimmed
- 4 Tbsp unsalted butter, divided, plus more to grease casserole
- 2 1/2 Tbsp all-purpose flour
- 2 cups half and half, (or equal parts milk and heavy cream)
- 2 tsp garlic salt
- 1/4 tsp black pepper
- 1 cup parmesan cheese, divided
- 1/2 cup Panko bread crumbs
Instructions
- Preheat Oven to 400˚F with the rack in the center. Butter a 9x13 casserole dish. Arrange trimmed asparagus in prepared casserole dish, packing it down for a fairly flat and even surface.
- Place a saucepan over medium heat. Melt in 3 Tbsp butter then add 2 1/2 Tbsp flour and whisk constantly for 3 minutes or until butter just starts to turn golden in color. Whisk in 2 cups half and half, 2 tsp garlic salt and 1/4 tsp black pepper. Whisk until sauce just starts to thicken then remove from heat. Sprinkle in 1/2 cup parmesan and whisk until cheese is melted and incorporated.
- Pour sauce evenly over the asparagus, leaving about 1" space on the long sides of the casserole dish. Bake uncovered at 400˚F for 15-18 minutes (depending on thickness of asparagus), or until asparagus reaches desired tenderness.
- While the casserole is baking, make the topping: in a small mixing bowl, melt 1 Tbsp butter. Mix in 1/2 cup bread crumbs, stirring until evenly moistened, then stir in 1/2 cup remaining parmesan cheese. Halfway through baking, sprinkle the bread crumb topping evenly over the casserole then return it to the oven to finish baking.
- When asparagus has reached desired doneness, set oven to broil for 2-3 minutes or until bread crumbs are golden brown. Remove from oven and serve.

Made it, sauce did not come out as directed. Threw it out. Remade using Alfredo Sauce and Panko. Tasted GREAT. Why make the sauce and make it complicated.
Hi, You can absolutely use your favorite store-bought alfredo sauce to make it even easier. Without being there or having more information, it’s difficult to troubleshoot. I guess, I would suggest making it per the recipe without substituting any ingredients.
It was ok. I thought the sauce needed more flavor. Maybe fresh garlic and more salt.
Thank you for that feedback, Roni!
I pray that I am doing this right. I am new to the iPAD. I loved your Asparagus Alfredo recipe. How inventive. Ok I’m going to put my name and email and hope that I can see more recipes.
Thank you so much for subscribing!
Its Jane, again, I can’t wait for new recipes, Ive seen some others, they
Are absolutely fabulous. Thank goodness I at least know how to type. I haven’t got a clue how to join the service, but I will be looking for recipes whenever you feel so inclined. Thank you. Jane
I’m so happy you are enjoying our recipes, Jane!
Hi Natasha! Can I make It in aluminum dish instead ? I found it’s a bit bigger than 9×13 and I’m looking to cook it for a 14 + people, I just really don’t want to screw it as a side dish for a Thanksgiving, it look so delicious ❤️Thank you
Hi Tiana, that should work, but when using a larger pan, I would make sure the asparagus is well covered in sauce. You could also lightly season the asparagus with salt and pepper before pouring on the sauce.
Hi! I love your recipes! Question: I want to make this for Thanksgiving, but the other items that will need to be in the oven at the same time as this dish need to be cooked at 350 degrees instead of 400. Do you have any suggestions how to possibly cook this at a slightly lower temperature? Thanks in advance! Happy Holidays!
Hi Ana Maria, that should work, it will take longer with other items in the oven however at the lower temp. I hope it goes well!
Oh My, I hope that I have done this right. I am new to an iPAD. I loved your Asparagus Alfredo Recipe. How
I’m so happy you enjoyed that. Thank you for sharing that with us!
do you think this would turn out fine if I made it a day ahead of time, refridge’d, then popped in oven?
Hi Tommy, I haven’t tested that but I think it could work. If you experiment, let me know how you liked the recipe
We’re cooking for a dozen or so for Masters weekend and I want this on the table. I test drove a half recipe to get the feel for it before doubling it on the day of, and have a couple of questions. I thought the sauce was totally killer before it ever went on the asparagus and actually seemed to degrade a bit or curdle in the cooking. Also the uncovered ends just tasted like plain asparagus with no seasoning. I’m wondering whether first tossing the asparagus with EVOO and kosher salt and par cooking in the microwave for a minute two wouldn’t benefit all concerned: the sauce wouldn’t breakdown and all the asparagus would be seasoned…whatdaya think? Also might make it easier to get to the table on “the day” since we’ll be oven challenged. 🙁
Enjoying your stuff…
Bill
Hi Bill, I haven’t had any issues with separating in the sauce – I wonder if maybe an ingredient substitution or change in the process might be the culprit? Also, if you continue cooking the sauce after adding the cheese, it can curdle as with most alfredo sauces. You can toss with salt and pepper and oil initially if you prefer – no harm in doing that.
I appreciate that. Definitely not from substitution, but I may have added the cheese while still on the heat and left it a minute. I’ll have it right by Saturday for sure!
Hі there, I log on to you blog liқe every wеek.

Can you tell me where you got that handled casserole dish? I’ve been looking for one like that. Can’t wait to try this recipe, it looks delicious!
Hi Janet, thank you! I purchased the casserole dish at my local Fred Meyer. I believe it was about $20 and it has held up really well. My local Fred Meyer still carries it in Idaho but I haven’t been able to find the same one online.
Ca you use mozzarella cheese instead of Parmesan?
Hi Iv, we love it with parmesan and the flavor profile. I haven’t tested that with mozzarella but that should work!
Iv
Yes it does!
