That sad, dry brick taught me a crucial lesson: temperature is not just a suggestion—it’s the whole show. You can’t wing it with meatloaf, because a few degrees off separates a tender, juicy dinner from a flavorless hockey puck. So let’s cut through the confusion right now.
The magic number is 350°F (175°C). That’s your sweet spot for a standard loaf. It’s hot enough to brown the outside and cook the inside evenly, but not so hot that it shrinks into a sad little rock. (Yes, ovens have personalities, but 350°F is universally forgiving.)
But Wait—What About the Center?
Here’s the real kicker: the oven temp is only half the battle. You need to know your internal target, and that’s 160°F (71°C) for ground beef. Pull it out at 165°F, and you’re already in “dryville, population: your disappointment.”
I always say, trust the thermometer, not the timer. A meatloaf can take anywhere from 45 minutes to 1 hour 15 minutes at 350°F, depending on its size and shape. Use an instant-read probe like a secret weapon—poke the thickest part, and when it hits 160°F, stop.
