Crustless Asparagus-Mushroom Quiche

During the “stay at home” orders, I have decided to work on a couple of new recipes that both my brother and I would enjoy. Knowing that he likes asparagus, one recipe I settled on was an asparagus quiche. I modified this recipe after reading through many online recipes. We both enjoyed it very much.

RECIPE

1.    Preheat oven to 350ºF with the oven rack in the center shelf. You may wish to place a baking sheet on the rack to prevent spills during cooking. 

2.    Prepare veggies. Using a chef’s knife, peel and dice the onion on the cutting board. Place the pieces in your mixing bowl. Bend a representative piece of your asparagus enough so that it snaps in two. Line the top of the piece up with the tops of the remaining uncut asparagus on your cutting board and slice all of the asparagus to the same length. You will use the top pieces for the quiche. Cut those into equal length pieces between ½ and 1” and toss those into the bowl with the onions. The woody bottom ends can be frozen for making soup later, composed, and even fed to your pets. My dogs love them (and get asparagus pee!). Finally, clean and dry the mushrooms. Slice them into 3-5 slices each and put the slices into your bowl.

3.    Sauté vegetables. Bring a skillet up to temperature over medium heat. Once hot, add the olive oil. When the oil begins to shimmer, add your veggies all at once with a pinch of salt. Stir frequently, ensuring that the veggies are not burning. If they seem to be burning or sticking, reduce the heat on your pan. Then, mince the garlic. Remove the parsley leaves from their main stalks, mince and then add both the garlic and parsley to your pan. (If you prepare your ingredients in advance, you will want the veggies to sauté for about 5 minutes before adding the remaining ingredients). Add the curry powder and thyme, ensuring you are not getting any stalks from dried or fresh thyme in the pan. You can rub dried thyme between your palms to crush any stalk pieces and release the essential oils. You can easily pull leaves off of fresh thyme by gently grabbing the bottom of the stalk and pulling upward. Sauté, stirring frequently, until the onions and asparagus are soft – about 10-12 minutes. Turn the heat off and allow the veggies to cool somewhat.

4.    Make the custard. Great the cheeses. 8 oz is about 1 standard block. It is best not to buy pre-grated cheese because those cheese are specially made to not stick together when packaged… they don’t melt well. Break open 5 large eggs and put the contents in your bowl. It is best to break them into a separate bowl and pour each individually into the larger bowl, just in case there is a problem with the egg. Beat gently until the yolks are mixed evenly through the eggs. Add the half and half, mustard, salt, and pepper, and thoroughly, but gently combine. Add the grated cheese in and mix to combine well. Finally, add the veggies and mix to combine well. 

5.    Bake the quiche. Lightly grease your pie pan (this is optional as I find this really does not stick to my pan) with oil or butter. Add your egg and vegetable mixture to the pie pan, using a spoon or spatula to spread it out evenly. Place in the pie pan in the oven. Bake for 45 minutes, checking for doneness at 40 minutes. To check for doneness, place a knife into the thickest part of the center. If it comes out clean, your quiche is done.

Once baked, allow the quiche to cool for 5-10 minutes before slicing. Serve with fresh fruit, a nice salad, or even a bowl of homemade tomato soup. Enjoy!

Cook’s notes: this can be made with any vegetables of your choice, although vegetable quiches are traditionally broccoli or asparagus. Make sure whatever veggies you use are nice and cooked, but not soggy. Let your creativity be your guide.
