Pink Oyster Mushroom Quiche

It’s no surprise, that a quiche recipe is one of my first 100 articles on this Recipe, Nutrition, and Wellness blog because they are one of my favorite go-to brunch items. Quiches are fancy yet pretty easy to whip up! Thus, a homecooked quiche is a fantastic way to impress guests or to enjoy a delicious breakfast for one.

Serving a quiche at breakfast or brunch is simple and easy, it just takes a little time. Try making your quiche a day or two in advance for a quick breakfast with minimal clean-up. Once you are ready to serve breakfast, just pop a slice of your quiche in the microwave (on a microwave-safe dish). More on that later under “How to Make a Quiche”.

This no-fuss Pink Oyster Mushroom quiche is a terrific introduction to other quiche recipes. The luxurious pie crust, combined with fluffy eggs and beautiful vegetables, is a lovely way to start the day.

 Ingredients for this Pink Oyster Mushroom Quiche

Pink Oyster Mushrooms: I love mushrooms; they taste so good paired with eggs and thyme! Pink Oyster Mushrooms are similar to Blue Oyster and other Oyster Mushrooms, achieving their name by the way they grow on trees! They look like oyster clusters! Curious to know more about how to use Pink Oyster Mushrooms? Check out this post 10 Easy Recipes with Pink Oyster Mushrooms You Have To Try.

Kale: For this Quiche I use Kale. You can swap Kale for any other leafy green, such as Spinach, Arugula, or another vegetable like broccoli.

Onion: I used half a yellow onion because I wanted a strong, oniony flavor throughout the quiche. Looking for a more delicate flavored onion? I recommend using leeks, shallots, or scallions. 

Thyme

Eggs

Unsalted Butter or Olive oil for cooking the veggies

Optional – add something spicy: I love a bit of heat with my eggs. For this recipe, I went with jalapenos, but you could use hot sauce, red pepper flakes, or another hot pepper.

How to make a Quiche

Below are the six steps to make the perfect quiche.

The Crust 

A homemade or store-bought pastry crust works just fine. However, for convenience, I am pro-store-bought pie crust. It makes everything easier, simpler, and quicker! 

Roll out the crust on your pie pan, prick it with a fork in about 10-15 places, and then pop it in a preheated oven, at 350 deg F. Pre-bake the Kale and Cremini Quiche crust for 15min. This step is a must for a non-soggy crust.

The Veggie Filling

You can get adventurous with this part of the recipe. I like to use whatever veggies are available locally (i.e. from my local farmers market or CSA) and sautee them in a large skillet.

The filling equals about 2 cups of cooked and seasoned veggies. I add my herbs, salt, and pepper during this step. But, you can add the herbs and seasonings with the eggs.

The Eggs

While the crust bakes and the veggies cook, start whisking up the eggs.

Once you add the veggies to the baked crust, pour the eggs right over top. Eight large eggs are enough to fill up the quiche. 

The Bake

Now the uncooked quiche is ready to go in the oven. No need to change the oven temp, 350 degrees F is just fine and dandy.

Bake the quiche for 45min.

The Cheese

Once steps 1-4 are complete, it is time for the cheesy crust.

Sprinkle 4oz of shredded cheese evenly over the top of the cooked quiche.

Of note, there is a quick switch of oven temperature here; turn your oven to broil. Then, Pop the quiche in the oven for 5-10min.

At this step, you might want to make a tinfoil crust protector or use a pie crust shield to prevent the pie crust edges from burning. Taste of Home has a great article on how to make a pie crust shield. 

This next part is a bit subjective, so keep an eye out for cheese “doneness”. When making my quiches, I know my cheese is done when it has just started to brown (typically at about 7min).

Keep peeking at your crust every 1-2min. This process goes by quicker than you think!

Finishing Up

Once your cheese melts to your liking, remove the cooked quiche from the oven. Let it rest for ~10 minutes on the counter. After that, it is time to eat. 

Make this recipe a day or two in advance! Just allow the quiche to cool completely, to room temp (about 60-75min), then cover and pop it in the fridge. To reheat the quiche, cut the quiche into 6-8 slices and (depending on the slice size and microwave) place it in the microwave for 60-120 seconds.

Other Quiche Variations

I make a variation of this quiche often, but it’s never the same ingredients. Sometimes, I may change up the vegetables, cheese, herbs, and even type of mushroom!

I love to utilize vegetables from my garden or have been grown locally. Kale is one of those veggies I can get any time of the year here in the Columbia River Gorge. 

Some other vegetable combos by season:

  • Spring: Broccoli and cauliflower – using cheddar cheese
  • Summer: Tomato, garlic, and onion (or caramelized onion) – using parmesan cheese 
  • Fall: Butternut squash and sage – using goat cheese 
  • Winter: Carrot and parsnip quiche – using gruyere cheese

 

FAQ (Ask A Dietitian!)

What’s the deal with the different colors of eggs?

Egg color is determined by the breed of hen. Leghorn, White Rock, and Cornish hens lay white eggs. Orpington, Rhode Island, New Hampshire, and Plymouth Rock hens lay brown eggs. Some hens even lay blue eggs some green! 

Did you know?! Egg Shell Color does NOT affect the nutritional value of the egg. Research shows that eggshell color doesn’t indicate or cause a difference in nutritional value. 

However, research does suggest that other factors can lead to more nutrient-rich eggs. For example, a better diet, less stress, and access to the sun can lead to more nutrient-rich eggs. In other words, if you want super tasty eggs, get them from ethically raised chickens.

The serving size is a 4th of the quiche. I set it for this size if you are planning on eating this quiche alone for breakfast. Serve it in an 8th portion, like in the pictures, if you are serving this with a side of fruit, potatoes, or other breakfast noms!
