Equipment

  • 9x13-inch baking dish Greased with olive oil or non-stick spray
  • Large mixing bowl For whisking the egg mixture
  • Whisk
  • Large skillet or sauté pan For sautéing garlic and asparagus
  • Cutting board and knife For trimming and cutting asparagus
  • Measuring cups and spoons
  • Box grater If grating your own Parmesan; optional if using pre-shredded
  • Microplane zester For zesting the lemon
  • Oven mitts

Ingredients
  

  • 1 bunch fresh asparagus tough ends trimmed, cut into 1-inch pieces
  • 8 large eggs room temperature recommended
  • 1 cup whole milk 240ml
  • 4 oz goat cheese 113g, crumbled
  • 1/2 cup shredded Parmesan cheese about 50g
  • 2 cloves garlic minced
  • 1 tbsp olive oil 15ml
  • 1/4 tsp lemon zest from about half a lemon
  • salt to taste; about 1/2 tsp recommended
  • black pepper to taste; about 1/4 tsp recommended

Instructions
 

  • Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with olive oil or non-stick spray, coating the bottom and sides evenly.
  • Snap or trim the tough woody ends from the asparagus, then cut the spears into 1-inch pieces and set aside.
  • Heat olive oil in a large skillet over medium heat, add minced garlic, and stir for 30 seconds. Add asparagus, season with salt and pepper, and cook for 3 to 4 minutes until bright green and just slightly tender. Remove from heat and let cool slightly.
  • In a large bowl, whisk together eggs, whole milk, lemon zest, salt, and black pepper for about 1 minute until fully combined, pale yellow, and slightly frothy.
  • Spread the sautéed asparagus evenly in the prepared baking dish, crumble goat cheese over the top, pour the egg mixture over everything, then sprinkle shredded Parmesan evenly across the surface.
  • Bake on the center rack for 30 to 35 minutes, until the eggs are fully set in the center and the Parmesan topping is lightly golden. The center should not jiggle when the dish is gently shaken.
  • Remove from the oven and let the casserole rest for 5 to 10 minutes before slicing into 6 portions and serving warm.

Notes

  • Do not overcook the asparagus during the sauté step — it should still have a slight bite since it will continue cooking in the oven.
  • Use room temperature eggs for a smoother, more evenly textured egg custard.
  • Fresh asparagus is strongly recommended. Frozen asparagus releases too much moisture and can prevent the eggs from setting properly.
  • Whisk the eggs vigorously for a full minute to incorporate air, which results in a lighter, more tender casserole.
  • Do not skip the lemon zest — even a small amount significantly brightens the overall flavor of the dish.
  • Always let the casserole rest for at least 5 minutes before cutting so the pieces hold together cleanly.
  • Make-ahead tip: Assemble the casserole the night before, cover tightly, and refrigerate. In the morning, bake as directed, adding about 5 extra minutes for the cold dish.
  • Cheese substitutions: Feta is the closest swap for goat cheese. Ricotta can be stirred into the egg mixture for a creamier result.
  • Storage: Refrigerate leftovers in an airtight container for up to 4 days. Reheat individual portions in the microwave on medium power for 60 to 90 seconds, or in the oven at 325°F for 10 to 12 minutes covered with foil.
  • Freezer-friendly: Freeze individual portions wrapped tightly in plastic wrap for up to 2 months. Thaw overnight in the refrigerator before reheating.
