Roasted Asparagus, Green Onion, and Blue Cheese Frittata

If you are looking for a reliable weeknight dinner that doesn't require a lot of chopping or constant stirring, this frittata is it. It comes together in less than 30 minutes, but the flavors feel like they spent hours developing because we roast the asparagus first to caramelize those natural sugars and bring out a deep, nutty sweetness. The star here is definitely the blue cheese; it cuts through the richness of the eggs with that sharp, tangy punch you just can't get from feta or goat cheese.
I like to make this right after dinner when the kitchen is warm and everyone is relaxing, but honestly, it's delicious for brunch too. My biggest tip? Don't skip roasting the asparagus! If you were to just chop it raw and toss it in at the end, it ends up soggy and bland. Roasting it until it starts to blacken around the edges gives it that perfect texture that contrasts beautifully with the creamy custard of the eggs. Plus, using green onions (scallions) instead of chives adds a lovely crunch and a fresh bite right before you serve.

Ingredients
  

For the Roasted Asparagus
  • 1 bunch asparagus about 1 lb tough ends trimmed
  • 1 tablespoon olive oil
  • 0.5 teaspoon fine sea salt
  • 0.25 teaspoon freshly cracked black pepper
For the Frittata
  • 8 large eggs
  • 0.33 cup fresh blue cheese crumbles about 4 oz
  • 0.25 cup heavy whipping cream or half-and-half for less richness
  • 1 tablespoon unsalted butter
  • 0.5 cup green onion thinly sliced (white and light green parts only)
  • 0.25 teaspoon fine sea salt
  • freshly cracked black pepper to taste

Method
 

  1. Prep the Oven and Asparagus: Preheat your oven to 425°F (218°C). Line a large baking sheet with parchment paper for easy cleanup. Cut the woody, white ends off the asparagus stalks and discard them or save for stock. Toss the spears in the olive oil, salt, and pepper until evenly coated.
  2. Roast the Veggies: Spread the asparagus in a single layer on the baking sheet, making sure they aren't touching so they roast instead of steam. Roast for 10 to 12 minutes, or until the spears are tender-crisp and the tips have just begun to char and blacken. Remove from the oven and let them cool slightly.
  3. Mix the Eggs: While the asparagus is roasting, crack the eggs into a large mixing bowl or a wide-mouthed jar. Add the blue cheese crumbles and heavy cream. Whisk vigorously until the mixture is completely uniform in color and there are no large chunks of cheese left. Season with ¼ teaspoon salt and a few grinds of black pepper.
  4. Sear the Onions: Heat a 10-inch oven-safe skillet (cast iron works best) over medium heat. Add the butter and let it melt and foam slightly. Toss in the sliced green onions. Cook for about 3 to 4 minutes, stirring occasionally, until the onions are wilted and translucent but still have a bit of crunch.
  5. Combine: Give the egg mixture one last whisk to incorporate any cheese that may have stuck to the bowl. Pour the liquid mixture over the sizzling green onions in the skillet. Let it sit undisturbed for about 2 minutes until the edges just start to set and look slightly puffy.
  6. Add the Asparagus: Scatter the roasted asparagus pieces evenly over the top of the frittata mixture. If you want a crispy crust, you can sprinkle an extra teaspoon or two of blue cheese on very top.
  7. Bake Until Set: Carefully transfer the skillet to the preheated oven. Bake for 15 to 18 minutes. The frittata is done when the center is just set—meaning it looks firm but still slightly jiggly in the very middle (it will finish setting as it rests). Do not overbake, or you risk rubbery eggs.
  8. Serve: Remove from the oven and let it rest for 5 minutes. This allows the custard to fully set so it doesn't run when you cut it. Slice into wedges and serve warm.

Notes

Substitutions: If you aren't a huge blue cheese fan, try swapping it for crumbled Gorgonzola or even a sharp cheddar mixed with some goat cheese. You can also use spinach instead of green onions if you have that on hand.
Storage: This frittata keeps well in an airtight container in the fridge for up to 3 days. It actually tastes better the next day as the flavors meld together! Reheat individual slices in the microwave or toaster oven until warm.
Serving Suggestions: Serve this with a simple green salad dressed in a lemon vinaigrette to cut through the rich eggs and cheese, or alongside some crusty sourdough bread for dipping into any leftover runny yolk goodness.
