How to make an asparagus egg casserole

This scrumptious egg casserole can be cooked in a conventional oven or air fryer toaster oven. Either way requires only minimal cooking skills.

  1. Mix the eggs, half and half, and seasonings.
  2. Add egg mixture to a prepared baking dish.
  3. Add other ingredients (asparagus, bacon, and cheese).
  4. Bake until golden brown and eggs are set.

Asparagus egg casserole takes about 15 minutes in the air fryer and about 30 minutes in a conventional oven.

Tips for the best asparagus breakfast casserole

This casserole is extremely forgiving and totally adaptable.

  • Use an extra sharp cheddar or substitute a premium cheese like Gruyere.
  • Always use fresh, young asparagus. Because it's thin, it cooks more quickly and keeps the moisture content balanced in the egg casserole.
  • Use free-range or farm-fresh eggs because their fresh amber yolks add more color and flavor to the egg casserole.
  • If your family or guests aren’t team asparagus, swap it out for another green vegetable like broccoli, broccoli rabe, spinach, or kale.
  • Turn your egg casserole into a Tex-mex style breakfast by simply adding peppers, onions, and taco seasoning!

How to make bacon egg casserole vegetarian

If you’re cooking for a vegetarian crowd, simply omit the bacon. You could always substitute a veggie bacon or meatless breakfast sausage to match texture and saltiness. If you don’t want a meat substitute in your egg casserole, consider adding more salt to balance the flavors. Also, check out my Vegetarian Crustless Quiche Recipe.

How long does egg casserole need to cook?

Asparagus egg casserole should have a springy texture, even with ingredients added in. So, it’s important to cook it properly. In the air fryer, cook the casserole for at least 15 minutes, or until eggs are completely set, lightly browned, and have risen slightly. The same will apply in a conventional oven, but the total cook time will be closer to 30 minutes.

  • knife and serving utensil
  • airtight food storage containers

What to serve with breakfast casserole

When serving egg casserole for brunch, toasted croissants or a French loaf are pretty irresistible. If carbs aren’t your thing or you prefer gluten-free, a light fruit salad with acidic fruits will help cut the savoriness of the bacon and cheese. Pair both with this scrumptious egg and asparagus casserole for a elegant holiday brunch.

Traci's Recipe Notes

How to make the best asparagus breakfast casserole
  • Always use fresh, young asparagus because it’s thin, so it cooks more quickly, which prevents the eggs from overcooking.
  • Use free-range or farm-fresh eggs because their fresh amber-colored yolks can impact the color and flavor the casserole.
  • Substitute the cheddar cheese with Gruyere, provolone, or even goat cheese.
  • Substitute the asparagus for a low-moisture vegetable like broccoli, cauliflower, broccoli rabe, spinach, or kale.

Equipment

  • measuring cups and spoons
  • mixing bowl
  • wire whisk or fork
  • 9 x 6 baking dish
  • oven or air fryer oven
  • knife to cut casserole
  • serving utensil
