How to Make Asparagus Casserole
Prepare your asparagus by washing it well and then patting them dry with a paper towel. You could also just let them dry in a colander.
Snap the ends off of the asparagus to remove the hard pieces first, you could also just cut them off with a knife instead.
Set the cut asparagus aside and toss the hard pieces in the trash because you won’t need them.
Cut your bacon into strips and place them off to the side.
Preheat your oven to 392 degrees F.
Create the bechamel sauce in a pan for the casserole by first melting the butter.
Then add in grated or tiny chopped garlic cloves. Cook on medium-low heat until fragrant.
Add in the flour and let it brown while you keep stirring. It will stick to the melted butter and create a thick batter. Don’t worry, just keep going.
Add in the milk a little at a time while whisking to dissolve the formed batter into the milk.
Once the batter and the milk have been combined, add in the Italian herbs and grated nutmeg.
Add in the salt as well.
Continue to stir the sauce until thickened. You will know that it has thickened when it can stick to the back of a spoon.
In a baking dish, add the asparagus in one even layer.
Add in the bacon strips on top of that and then cover them with the bechamel sauce.
Add the parmesan cheese on top and cook on the middle rack of your oven for 20 minutes at 392 degrees F.
If your bechamel sauce it’s getting difficult to combine, feel free to use an immersion blender and blend it until a smooth sauce is achieved. Once you have a smooth consistency keep cooking until it thickens as said.
Do not skip the browning of the flour, since it would give a raw flour taste to your bechamel sauce that is not nice.
You can also cook the bacon beforehand so it will release less grease into the casserole.
Should I use thick or thin asparagus?
You can use either one depending on what is easier to find or what you may prefer. Thicker asparagus may take a little longer to cook whereas thinner asparagus will cook faster and can be a softer texture once finished.
Can I make the asparagus casserole recipe in advance?
Yes, you can prepare this dish up to a day in advance and keep it well covered in the fridge. Then when you are ready to bake it, just take the pan and place it on the counter to rest for a few minutes as the oven preheats. Then bake as directed. Do not go straight from the fridge to hot oven or else your pan can break.
How long are asparagus casserole leftovers good for?
The leftovers from this dish can be kept stored in an airtight container in the fridge for up to 3 or 4 days. Just reheat it when you are ready to eat.
