Can I prepare Baked Egg Boats ahead of time?
Yes. Fill the baguette boats, cover with plastic wrap, and refrigerate up to 8 hours before baking. Add 2–3 minutes to the baking time if baking from cold.
What can I substitute for Gruyère cheese?
Swiss, Emmental, or aged Cheddar work well. Avoid mild cheeses that won't add depth of flavor.
How do I know when the eggs are cooked through?
The filling should be set but slightly jiggly in the center when gently shaken. It will continue to cook as it cools. Overbaking dries out the eggs.
Can I use bacon instead of pancetta?
Yes. Use the same amount of cooked, crumbled bacon. The flavor will be slightly smokier.
How do I hollow out the baguette without breaking it?
Use a serrated knife to carefully cut a shallow trench along the top, then use a small spoon or melon baller to scoop out the interior crumb, leaving a 1/4-inch shell on all sides.
