• One of my favorite comfort foods to make in a slow cooker is pot roast.
• However, my family's recipe for slow-cooked pot roast is a little different than most.

When it comes to home cooking, my mother knows exactly what she's doing.

One recipe that I've eaten many, many times throughout my life is my mom's slow-cooked pot roast. I use my Crock-Pot pretty often, so I hoped I would be able to nail the dish — or at least get pretty close to how I remember my mom's version turning out.

My mom told me she first got a version of the recipe from a coworker. However, she's been making it consistently for about 10 years, and her spin on the original recipe involves adding carrots and mashed potatoes as a side dish.

Here's how to make my mom's family-favorite pot roast.
