01 -
Get your oven ready by setting the rack in the middle and warming it to 350°F (175°C). Cover a rimmed baking sheet with foil.
02 -
Cut the mozzarella into small cubes and pop it in the fridge while you work on the meat.
03 -
Beat eggs in a big bowl. Throw in the almond flour, Worcestershire, onion powder, salt, garlic powder, and pepper, and mix it all up. Add your ground meat and blend with your hands just until mixed - don't overdo it.
04 -
Take about two-thirds of your meat mix and put it on the foil-lined sheet. Shape it roughly into a 9x5-inch loaf. Make a hollow area in the middle about 7x3 inches, leaving a 1-inch meat border all around.
05 -
Dump the diced mozzarella into the hollow part, spreading it evenly. Top with your leftover meat mixture, pressing down to make it flat and making sure the cheese is totally sealed inside.
06 -
Cook until it's nicely browned all over and the middle hits at least 165°F (74°C) when checked with a meat thermometer, about 55 to 60 minutes.
07 -
Let it sit for 15 minutes before cutting. This gives the juices time to settle and the cheese won't run out everywhere.
