What sides to serve with pot roast?

One of the best sides to serves with pot roast always involves potatoes. Of course, many sides go well with this dish, but vegetables are always your best bet. Here are some of the more common choices.


Make sandwiches – You can make sliders or normal sandwiches. Top with BBQ sauce or other condiments for a new dinner entirely.

Make it spicier – The peppers add a touch of spice, but not a ton. You can add some hot sauce, crushed red peppers, jalapenos, or other, hotter, peppers to kick it up a notch.

Make it mild – Nix the peppers altogether for less spice.

Add veggies – You can toss in potatoes and carrots 4 hours into the cooking process. Onion is also a good choice and popularly used.

Slice instead of shred – You can always slice the roast instead of shredding it, if preferred.


Refrigerate – Store in a sealed container for up to 3 days.

Freeze – Store in an airtight container for up to 2 months.

Reheat – Reheat using the microwave.

Tips and techniques

Don’t add liquid – If you feel it needs liquid, resist the urge. The roast will release plenty of juices during the cooking process.

Sear the roast – For a nice browned color. Sear it quickly in a skillet on all sides before placing in the slow cooker.

Don’t use salted butter – Unless you like an overly salty roast, go with unsalted butter.

Use powders – When adding dressings or gravy mixes, use the powder form, not the liquid form. Otherwise, there will be too much liquid once finished.

Use other types of roast – Although it won’t be the original Mississippi pot roast recipe, you can use other types of meat such as chicken, pork, etc.
