How to Reheat Bacon in The Oven

How to heat bacon in the oven is a key kitchen skill to have, especially when you are reheating Canadian bacon for a big group. 

See an overview of all the different methods to reheat bacon in 2024 here.

Why – simply put, apart from a commercial bain-marie, the oven is the most efficient way to reheat bacon for a crowd. 

How to Reheat Large Amounts of Bacon

  • 95% of all professional chefs questioned said this is the method they would use at home to reheat bacon for between 4-20 people

The oven is not the fastest method however, reheating bacon in a panini press is a relatively fast way, but for a smaller group.

How to Reheat  Bacon in The Oven

Reheating fried bacon in the oven starts by preheating the oven to 350°F. Next, place the cooked bacon pieces on a tray lined with parchment paper or a baking sheet.

I would typically heat the leftover bacon for 6 minutes and then check if it has reached the temperature or degree of crispiness I need. This is a little longer than reheating leftover bacon using an air fryer.

Typically I will put it back in for a further 2-3 minutes if I want the back to crack or crisp up some more.

For streaky or American bacon, it will take 6-7 minutes to be hot enough to consider it is ready to eat.

Canadian bacon will take 7-8 minutes to be fully reheated.

This method also works for bacon bits, boiled bacon, and baked bacon reheating.

Using a Griddle to reheat bacon for a crowd is an alternative to the oven.

What Oven Rack Position Do I Reheat Bacon On

If you’re not familiar with oven rack position, here’s a quick primer:

The Oven Rack position(turkey) choices are

  • lower
  • middle
  • top

If you just have one tray of bacon, use the middle oven rack position; it has the evenest heat distribution, especially if you have a convection oven or forced air.

When reheating bacon, I prefer to use a large rack because it allows me to place multiple slices of bacon side-by-side in the same pan. This makes it easier to flip them over when needed.

Another benefit of using a large rack is that it helps prevent burning, especially if you rotate the tray of bacon halfway through the reheating process to ensure all bacon is reheated evenly.

You can also line a large baking sheet with foil to save on the clean-up afterwards. Place the bacon strips on the prepared baking sheet and bake until crispy.

Once cooked, remove the bacon from the oven and let cool slightly. Then transfer the bacon to a paper towel-lined plate and pat dry.

How Do I Make the Bacon More Healthy when Reheating in The Oven?

One of the things I like about my air fryer is the bacon grease or fat drips off during the reheating; if you want to achieve the same effect using the oven, then use a wire rack. This could also be a cake or cookie resting rack to raise the bacon off the tray.

This is also a reason why people like to cook crispy bacon in the oven, to begin with.

Place an elevated wire rack on an oven tray or over a cookie sheet and place the bacon on top, and follow the method below.
