Trucker’s Slow Cooker

Cooking in a big rig takes some ingenuity. Clever. Original. Inventive. It’s not like you’re at home with the stove, able to cook on four burners at the same time. But you can plug in a slow cooker and have a meal as good as you can make it at home.

What type of slow cooker is best?

There are two kinds of slow cookers to use in a truck – one with a regular plug that requires an inverter or the 12-volt type. Research both to see which you prefer. My trucker husband and I have a 2-1/2 quart Crock-Pot brand. The lid has latches that snap on to the handles. It is the typical slow cooker with a normal plug, not the 12-volt kind. We purchased a 12-volt slow cooker first but decided it was not the safest to use because of the possibility of the plug and/or outlet melting. Then he was given a new truck to drive with an inverter. Nice! That meant we could now cook truck meals in a slow cooker.

It’s best to buy a slow cooker with a lid that latches onto the handles. You can use one without the latches, but be sure to secure it with heat-resistant pads and/or towels so that bumpy rides won’t slosh your food everywhere or melt anything near the appliance.

Watch for sales. Target had a 2-1/2 quart slow cooker with the latches on sale recently. I bought one, and my husband tried it out for the first time this week. The first meal he made was a pot roast with vegetables that were purchased already pre-packaged with a package of seasoning included.

All that had to be done was open the bags, apply the seasoning on the meat and vegetables, and place it all in the slow cooker.

First, he placed a slow cooker liner inside.

Next, he added the vegetables, then the meat on top.

He only used part of the seasoning to minimize the amount of sodium.

When my husband placed the roast on top of the vegetables and put the lid on, he said the meat was touching the lid. You’re supposed to fill the slow cooker to 1/2 or 2/3’s full.

Either you can use smaller portions of meat, or use a larger slow cooker. Next time we will buy the meat and cut it into smaller portions. One good thing, though, was he had plenty of roast for the week!

The pot roast cooked for eight hours, and the meat was falling-apart tender.

  • Pre-packaged pot roast and vegetables


  1. Place a slow cooker liner inside the crock, tucking in the bottom and along sides snugly, then over the top.
  2. Open the bag of pre-packaged vegetables and place them in the bottom of the liner.
  3. Open the bag of pot roast and place it on top of the vegetables.
  4. Open the seasoning bag and sprinkle as much seasoning that you desire on top of the meat.
  5. Put the lid on and latch it (or secure your lid if your slow cooker doesn't have latches).
  6. Cook on low for 8 hours.

  1. It looks like he put the veggies in the bottom and the roast on top. I usually put the roast in first and scatter the veggies around the edges. This works really well for pieces of meatthat are thicker than they should be for my slow cooker.

      I had told him to put the meat on top (the natural juice makes the veggies taste wonderful). But your idea is a good one, too, especially with a thick roast.
