The Basics: Oven Temp and Internal Temp for Smoked Ham

• Oven Temp: 325°F (163°C) is your golden rule for nearly every type of ham.
• Internal Temp:
  • Pre-cooked smoked ham: Heat to 140°F (60°C)
  • Uncooked smoked ham: Cook to 145°F (63°C)

Always check the label: if it says “fully cooked,” you’re just reheating. If it says “cook before eating,” it needs the full ride to 145°F.

3. Bake according to the timing above, checking internal temp during the last 30 minutes.
4. Glaze (optional): Remove foil for the last 30–40 minutes, baste with glaze, and bake uncovered until caramelized.

Chloe’s Quick Ham Tips

• Use a meat thermometer. Never just guess!
• Leave the rind on for the first 2 hours of cooking if your ham has one (keeps it extra juicy).
• Baste with glaze in the last 30–40 minutes for a sticky, beautiful crust.
• Save the bone! It’s gold for split pea soup or beans.
