Do I have to use a loaf pan?
No, and honestly I prefer not to. A free-form loaf on a parchment-lined sheet pan browns better and can help you avoid the greasy, steamed sides you sometimes get in a pan. If you only have a loaf pan, it will still work. Just drain off excess fat halfway through baking if needed.
How do I keep meatloaf from falling apart?
Two things: enough binder and enough rest. The egg plus breadcrumbs hold it together, and letting it rest 10 minutes after baking helps it set before slicing.
What internal temperature should it reach?
For ground beef, cook to 160°F in the center. If you use ground turkey or chicken, aim for 165°F.
Can I make it ahead?
Yes. Mix and shape the loaf up to 24 hours ahead, cover, and refrigerate. Add the glaze right before baking. You may need an extra 5 to 10 minutes bake time if it goes into the oven cold.
What breadcrumbs are best?
Plain breadcrumbs are the most neutral. Panko gives a slightly lighter texture. Crushed crackers also work in a pinch. If your crumbs are seasoned, reduce the added salt a bit.
Grated onion or minced onion?
Grated onion melts into the mixture and adds moisture (my favorite). If you prefer minced, chop it very fine so you do not end up with crunchy bits.
Want to use ground turkey instead?
You can. Turkey is leaner, so it can help to add a little extra moisture. Try an extra splash of milk or 1 tablespoon neutral oil. Bake to 165°F.
