Spring is brunch season. It is all about fresh flavors, brand-new in-season vegetables, lighter and warmer days, and gathering with your favorite people.
Egg bake breakfast casseroles are recipes to have on hand during this special season, whether for Easter brunch, Mother’s Day brunch, or any of the season’s occasions.
What I Love About This Asparagus Egg Bake Breakfast Casserole
When the days grow longer, and spring is fully upon us, I’m searching for recipes featuring one of my favorite veggies of the season: asparagus.
With its beautiful fresh spring green color and stately structure, its crisp yet tender texture, and its buttery, somewhat sweet flavor, asparagus is a perfect addition to meals.
I love using it in Cream of Asparagus Soup, frittatas, quiches, strata, or simply serving as Roasted Asparagus with Dill Yogurt Sauce.
But egg bake casseroles are the signature dish of brunch season. And this Asparagus Egg Bake Breakfast Casserole is a favorite. Much like our always popular Make Ahead Easy Vegetable Egg Bake Breakfast Casserole.
I love that this breakfast casserole can be made ahead, assembled the night before, and baked on the day you’re serving. It can also be baked immediately after assembly, making it a versatile dish.
In addition to being versatile and easy to make, it’s also so, so yummy! In fact, it’s so good that I’m always hoping for leftovers because they keep well in the refrigerator for quick snacks or on-the-go breakfasts.
Here’s to a delicious season ahead!

Hi Stephanie! Can you help clarify when we need to add the spinach. I couldn’t find if I needed to cook the spinach with the asparagus or add it uncooked into the casserole dish. Appreciate the clarification.
Hi Lisa! You can definitely add the spinach to the skillet when sautéing the asparagus and green onions. I usually add it to the dish with the sautéed veggies and leave it uncooked.
Hello..this recipe looks delicious. Can you tell me how much cheese to use, I only see the parmesan in the recipe, not the shredded cheese. Thank you!
Hi Bernadette! You will use a combination of Parmesan (for flavor) and 1 1/2 cups of your favorite shredded cheese like Mozzarella, Swiss, or Gruyère!
