Does your meatloaf hold together without a binder (ie eggs)? You mentioned a gluten allergy in the thread, I've had amazing results with quinoa in lieu of bread crumbs.
actually just made meatloaf tonight, here was my recipe cobbled together via the nobody's gone grocery shopping for a week and somebody used all of the Worcestershire sauce in bloody marys method:
2 pounds ground beef
1 pound mild italian sausage
2 small yellow onions
1 green bell pepper
2 sticks celery
1 tbs jarred minced garlic
1 cup bread crumbs
2 eggs
1 cup milk
1/4 cup sriracha ketchup
1/2 tsp liquid smoke
1/4 tsp anchovy paste
1/2 cup leftover veg french dip sandwich broth (portabella mushroom base)
1 tsp salt
1 tsp tony chachere creole spices
15 cranks of black pepper
Giant loaf on a baking sheet surrounded by slices of stale white bread to soak up the grease (those get thrown away) in the oven at 350 for 1 hour and 30-45 minutes, glaze with sweet baby ray's towards the end of cooking.
Not the healthiest dish but it fed 6 people + seconds with leftovers to spare. Served with mashed taters (including giant garden grown yukon golds!) and balsamic glazed carrots.
