Preheat & Prep Pan: Start by preheating your oven to a hot 425°F (220°C).
Place the 2 tablespoons (30 ml / 1 fl oz) of coconut oil in an 8-inch cast-iron skillet and put the skillet in the oven to get screaming hot while you prepare the batter. 2.
Blend the Batter: In a blender, combine the eggs, milk, egg white protein powder, baking powder, salt, and fresh dill.
Blend on high for about 60 seconds, until the batter is completely smooth and foamy. 3. Assemble the Dutch Baby: Using oven mitts, carefully remove the hot skillet from the oven. The oil should be shimmering. Immediately pour the batter into the center of the skillet.
Arrange the asparagus spears over the top and sprinkle generously with the shredded Parmesan cheese. 4.
Bake to Perfection: Return the skillet to the oven and bake for 18 to 20 minutes. You're looking for a dramatically puffed pancake with golden-brown, crispy edges. Resist the urge to open the oven door while it's baking! 5.
Serve Immediately: Remove the Dutch baby from the oven. It will begin to deflate, which is completely normal!
Spread with a little butter or coconut oil, slice into wedges, and serve right away for the best texture.
Don't open the oven door while baking! Peeking can cause your Dutch baby to deflate prematurely. Trust the process and wait for that golden-brown color.
