Let’s talk asparagus…

Right now, we are sitting in early June and in the middle of asparagus season. It is a really fun and different veggie to add into your rotation because it can be cooked up in oodles of ways (steamed, roasted, grilled or, you know, in an asparagus quiche) and just tastes like spring!

Asparagus is also loaded with goodness and it is an awesome source of fiber, vitamin A, vitamin C, and oodles of antioxidants.

Tips for making this veggie-loaded crustless quiche recipe with kids!

  • Asparagus is a great veggie for kids to help prep. Kids can snap the tough end off the asparagus then use a child-safe knife or a small pairing knife (depending on the child’s age) to slice each spear into small rounds.
  • Cut the potato into long, thin “stick” shapes then little helpers can easily chop the potatoes into small cubes.
  • If you are comfortable with your child cracking eggs, this is a great recipe for kids to practice that important cooking skill. Be sure to have a kitchen towel near-by to wipe up and little spills and hands (before washing up once all the eggs are cracked).
  • While you are cooking the veggies at the stove-top, kids can whisk the eggs with the remaining ingredients then help pour the mixture into the pie pan when the veggies are ready.
  • Sprinkling the cheese on top of the asparagus quiche before it goes in the oven (if using cheese) is a simple, quick way for even the youngest kids to get involved with this recipe.

Quiche can be enjoyed for all meals and you can make it fit into any time of the day by serving it with some lovely sides, such as a simple salad, fresh fruit, a smoothie, rolls/bread, or even soup during those colder months.

Suggested adaptations

  • Use whatever potato you have on hand. I like the thin skinned varieties best, but work with what you’ve got! You could also peel the potatoes if you’d prefer.
  • Make it dairy-free! Use unsweetened dairy-free milk and leave out the cheese.
  • Up the cheese! Cheese makes a good thing even better in my book, so feel free to stir in an – additional 1/4 to 1/2 cup of grated cheese in with the eggs if you like.
  • Use cream instead of milk for a richer, fluffier quiche. Or do half cream and half milk.
  • Add other soft herbs like basil and parsley. They would be great in addition to or in place of the chives. Again, use what you have.
  • Add extra veggies. Throw in extra asparagus, some chopped spinach or kale, sautéed mushrooms, or maybe even some tomatoes!
  • Make it as part of meal prep. Quiche recipes make for great leftovers! Make it for breakfast on a sleepy Sunday and then reheat the leftovers of lunches or an easy dinner in the coming days.
  • Add cooked bacon or ham. If vegetarian is not needed or you simply have some breakfast meats to use up, feel free to throw them into this crustless quiche recipe.

This Crustless Potato and Asparagus Quiche recipe is the perfect easy vegetarian meal. Enjoy it for breakfast, lunch, or dinner! It’s a delicious and simple way to eat more veggies. Plus, it’s naturally gluten free.

Ingredients
 

  • 1 Tablespoon olive oil or avocado oil
  • 2 medium Yukon gold potatoes, cut into 1/4 inch dice (about 1 heaping cup)
  • 1/2 bunch asparagus, trimmed and cut into small rounds (about 1 cup)
  • 1/2 teaspoon course salt, divided
  • black pepper, to taste
  • 6 large eggs
  • 1/2 cup milk of choice
  • 1/4 cup chopped chives, can sub scallions
  • 1/4 cup grated cheese , optional

Instructions
 

  • Preheat oven to 350℉ and grease a 9-inch pie plate.
  • Heat oil in a large skillet over medium-high heat. Add diced potato and cook, stirring occasionally, until pieces are golden brown.
  • Add chopped asparagus and cook until slightly tender, about 2 to 4 minutes depending on the thickness of your asparagus. The vegetables don’t need to be all the way cooked through yet since they are going to cook more in the oven.
  • Season with 1/4 teaspoon of salt and a few grinds of black pepper. Add vegetables to your prepared pie pan and spread into an even layer.
  • While vegetables are cooking, whisk eggs, milk, chives, remaining 1/4 teaspoon of salt, and a few grinds of black pepper in a large bowl. Pour egg mixture over the vegetables in the pie pan and give the pan a little shake to even everything out. Sprinkle the cheese over the top, if using.
  • Bake until set and lightly golden brown on the top, 18 to 22 minutes. Allow to cool for 10 to 15 minutes then slice into wedges. Serve warm.
