Ingredients

1 tablespoon extra-virgin olive oil
½ cup chopped yellow onion
1 pound fresh asparagus, trimmed and cut into 1-inch pieces
2 cups packed baby spinach
2 teaspoons fresh thyme leaves
2 cloves garlic, minced
6 large eggs
½ cup half-and-half
1 tablespoon Dijon mustard
¼ teaspoon salt
¼ teaspoon ground pepper
1 ½ cups shredded Gruyère cheese

Directions

Preheat oven to 375°F. Coat a 9-inch deep-dish pie pan with cooking spray.
Heat oil in a large nonstick skillet over medium heat. Add onion and cook, stirring often, until translucent, 2 to 3 minutes. Increase heat to medium-high and add asparagus; cook, stirring often, until the asparagus is tender-crisp, 3 to 4 minutes. Add spinach, thyme and garlic; cook, stirring constantly, until the spinach is wilted and the garlic is fragrant, 1 to 2 minutes. Remove from heat and let cool for 10 minutes.
Whisk eggs, half-and-half, mustard, salt and pepper in a medium bowl. Gently stir in the asparagus mixture and cheese; spoon into the prepared pie pan. Place the quiche on a rimmed baking sheet and bake until set and golden brown around the edges, 30 to 35 minutes. Let stand for 10 minutes before slicing.

Equipment:

9-inch deep-dish pie pan

Frequently Asked Questions

Are spinach and asparagus good for you?

Both spinach and asparagus are loaded with nutrition, including vitamin C, folate and vitamin K. Spinach also offers a healthy dose of vitamin A, and asparagus provides more fiber than spinach. The nutrients in these green veggies are also linked with healthier blood pressure and stronger bones.
Are eggs healthy?

Eggs are convenient little packages of nutrition. They offer complete protein, vitamin B12 and choline. The egg yolk contains the antioxidants lutein and zeaxanthin, which can help protect vision, and the protein in eggs can help stabilize blood sugar. While eggs used to get a bad rep for being high in cholesterol, we now know that dietary cholesterol has minimal impact on the amount of cholesterol in our bodies.
Can I substitute another cheese for the Gruyère ?

Absolutely. Some good substitutions include Emmentaler or Swiss, Comte, mozzarella or Cheddar.
What can you do with leftover yellow onion?

If you have a leftover onion with no plan to use it right away, we recommend refrigerating it in an airtight container (glass is best because plastic absorbs strong odors). Note: The container needs to be airtight because the smell will permeate nearly everything in your fridge. The onion should be good in the fridge for about a week. You can do so many things with leftover onions. You can caramelize them and use them on burgers, pizzas or steaks. You can roast them in the oven for about 25 to 30 minutes until golden brown and serve them with roasted meats or add them to salads. And there's nothing like Air-Fryer Blooming Onions.
What’s the best way to trim asparagus?

The best and quickest way to trim asparagus is to line up the spears on a cutting board and slice across the woody ends all at once, discarding an inch or two at the bottom (depending on the size of the stalk). For this recipe, you'll cut the asparagus into inch-long pieces, so once the woody pieces are gone, you can keep slicing across as needed. After trimming asparagus, some cooks like to then use a vegetable peeler to shave the last few inches of stalk. However, this step may be unnecessary unless your asparagus has very thick stalks or you're using white asparagus.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
