Ingredients needed

This asparagus frittata is a family favorite — for both breakfast and lunch! It’s seriously so tasty and even while using simple, easy-to-find ingredients. Here’s what you’ll need:

• Asparagus: This vegetable not only tastes delicious but it is super healthy! Learn more about all of the many health benefits of asparagus from Healthline.
• Onion: Adds a nice savory flavor to the frittata.
• Butter: For sautéing the onion and adding to the richness of the recipe.
• Eggs + egg whites: The base of this dish is made with 6 eggs and 1/2 cup of egg whites, which makes this high in protein with plenty of healthy fats from the yolks. Looking for another way to use up those egg whites? Try these egg white muffins!
• Milk: Just 1/4 cup of milk gives the frittata the perfect texture. You can use whatever milk you’d like. We typically use 2% for plenty of richness.
• Cheese: Shredded Swiss cheese and crumbled feta or any cheese you’d like! 
• Sea salt + pepper: To bring out all of the flavors.

How to make this recipe

Frittatas are similar to omelettes but they are not folded in the center, which allows them to be thicker and fluffier. The mix-ins are cooked in the skillet, and then the egg mixture is poured in, rather than the add-ins just being in the center. As an added plus, where omelettes usually just serve one, this frittata is cut into slices and serves six. Here’s how to make it: 

1. Cook asparagus: Preheat oven to 350 degrees Fahrenheit. Trim asparagus, cut into 1-inch pieces, and steam for 3-4 minutes, or until tender, in a steamer basket until tender.
2. Make the egg mixture: In a large bowl combine eggs, egg whites, milk, and half of the salt and pepper. Whisk together and set aside.

3. Sauté the onion: Heat butter in a 10-inch oven safe, non-stick pan or cast iron skillet. Add onion and cook for 5 minutes or until fragrant and translucent. Stir in the asparagus and the remaining salt and pepper.

4. Add the cheese: Turn off the heat and pour the egg mixture into the pan with the veggies. Sprinkle in the Swiss cheese, gently pushing it into the eggs mixture and then sprinkle feta over the top.

5. Bake: Pop the pan into the oven for 20-25 minutes or until set. Cool and enjoy.

Variations

We love this frittata recipe as-is, but it’s also really easy to customize. Here’s some options:

• Vegetables: Swap out the asparagus with another favorite cooked vegetable. Try spinach, mushrooms, baby potatoes, sweet potatoes, cauliflower, broccoli, or carrots. You could even do a combination of two or three that add to about 1 pound. Just make sure they are chopped up and cooked before adding them to the mix.
• Cheese: Instead of Swiss cheese, try using shredded cheddar cheese or shredded pepper jack. And instead of the crumbled feta, you could use goat cheese or gorgonzola cheese.
• Protein: The recipe is naturally vegetarian, but if you’d like to add in some meat, try cooked turkey sausage, cooked diced ham or cooked crumbled bacon. Crispy, crumbled bacon would also be delicious just crumbled over the top before serving.
