Here's the recipe I used to bake them in little bread bowls. The temp was a bit lower but the time for both is about the same. The eggs were done perfectly with creamy yolks and firm whites.
Baked Eggs in Bread Bowls
Adapted from Noble Pig, who was inspired by All You
crusty dinner rolls, as many as you want
large eggs – one for each roll
chopped fresh basil, parsley, chives, tarragon – anything you like
cream
salt and pepper
grated Parmesan cheese or gruyère , or anything sharp (old cheddar, Gouda, Asiago…)
Preheat the oven to 350F. Slice the top off of each roll and remove the bread inside, leaving just the crusty shell (don’t make it too thin-leave some bread in there for insurance against leaking). Place them on a baking sheet and crack an egg into each roll.
Top each egg with some herbs, salt and pepper and about a teaspoon of cream. Sprinkle with Parmesan or other cheese.
Bake for about 20 minutes, until eggs are set and bread is toasted. If you like, brush the tops of the buns with a little butter or oil and add them to the sheet about halfway through, to toast them as well.
