For a classic meatloaf, plan on about 1 hour in the oven at 350°F (175°C) for a standard 2‑pound loaf, but always cook until the center reaches 160°F (71°C).

Basic timing by size (350°F, regular oven)

  • 1 lb meatloaf: 35–45 minutes, then check internal temperature.
  • 1.5 lb meatloaf: 45–60 minutes.
  • 2 lb meatloaf: 55–75 minutes (about 1–1¼ hours).
  • 2.5 lb meatloaf: 80–95 minutes.
  • 3 lb meatloaf: 90–120 minutes (1½–2 hours).

The safest rule is: the meatloaf is done when the thickest part reaches 160°F, not just when the timer goes off.

Quick practical tips

  • Use a thermometer: Color alone can mislead; aim for 160°F in the center.
  • Loaf pan vs. free‑form: A free‑form loaf on a baking sheet cooks a bit faster than a tightly packed loaf pan.
  • Hotter oven (375°F): Shaves some time but risks drying the outside; many home cooks stick with 350°F for juicier results.

For your article SEO, you can anchor around “how long do you cook meatloaf in the oven” and explain that time is a guideline, but internal temperature is the real safety and juiciness target.

Mini‑TL;DR: At 350°F, a 2‑pound meatloaf usually takes around 1 hour, and it’s ready when the center hits 160°F.
