Cooking a roast in a slow cooker is a great way to prepare a delicious and tender meal with minimal effort. However, one of the most common questions people have when cooking a roast in a slow cooker is how long to cook it. The cooking time will depend on several factors, including the size and type of roast, the temperature of the slow cooker, and the level of doneness desired.
Understanding the Factors that Affect Cooking Time
Before we dive into the specifics of cooking a 3 lb roast in a slow cooker, it’s essential to understand the factors that affect cooking time. These factors include:
Size and Type of Roast
The size and type of roast will significantly impact the cooking time. A larger roast will take longer to cook than a smaller one, and a roast with a higher fat content will cook faster than a leaner one. For a 3 lb roast, you can expect a cooking time of around 8-10 hours on low or 4-6 hours on high.
Temperature of the Slow Cooker
The temperature of the slow cooker will also impact the cooking time. A slow cooker on the low setting will cook the roast at a temperature of around 180°F (82°C), while a slow cooker on the high setting will cook the roast at a temperature of around 300°F (149°C).
Level of Doneness Desired
The level of doneness desired will also impact the cooking time. If you prefer your roast to be rare, you will need to cook it for a shorter amount of time than if you prefer it to be well done.
Cooking a 3 lb Roast in a Slow Cooker: A Step-by-Step Guide
Now that we’ve discussed the factors that affect cooking time, let’s move on to a step-by-step guide on how to cook a 3 lb roast in a slow cooker.
Step 1: Prepare the Roast
Before cooking the roast, make sure to prepare it properly. This includes seasoning the roast with your desired herbs and spices, as well as searing it in a hot pan to create a crispy crust.

Once the roast is prepared, add it to the slow cooker. Make sure to place the roast in the center of the slow cooker, and add any desired vegetables or liquids around it.
Step 3: Set the Slow Cooker
Set the slow cooker to the desired temperature and cooking time. For a 3 lb roast, you can expect a cooking time of around 8-10 hours on low or 4-6 hours on high.
Step 4: Check the Roast
After the cooking time has elapsed, check the roast to ensure it has reached the desired level of doneness. Use a meat thermometer to check the internal temperature of the roast. For medium-rare, the internal temperature should be at least 145°F (63°C), while for medium, it should be at least 160°F (71°C).

What size slow cooker do I need to cook a 3 lb roast?
To cook a 3 lb roast in a slow cooker, you will need a slow cooker that is at least 6 quarts in size. This will give you enough room to fit the roast and some vegetables, if desired. If you have a smaller slow cooker, you may need to trim the roast to fit it in the cooker.
It’s also important to consider the shape of the slow cooker. A slow cooker with a round or oval shape will work better for a large roast than one with a square shape. This is because the roast will cook more evenly in a cooker with a round or oval shape.

The cooking time for a 3 lb roast in a slow cooker will depend on the temperature setting and the level of doneness desired. On the low setting, it will take around 8-10 hours to cook the roast to medium-rare, while on the high setting, it will take around 4-6 hours.
It’s also important to note that the roast will continue to cook a bit after it’s removed from the slow cooker, so it’s best to check the internal temperature of the roast after 7-8 hours on the low setting or 3-4 hours on the high setting. Use a meat thermometer to check the internal temperature, which should be at least 145°F for medium-rare.
