A delicious and easy dinner, this Slow Cooker Tangy Tomato Pot Roast is comfort food at it's best. An entire meal cooked all together in your slow cooker.

Welcome to March! I know some of you have been enjoying Spring-like weather already, but Winter persists here, so I thought I'd take some time to share one of my go-to comfort food dinners, before this comfort food season ends. (All throughout March, I will be sharing some of my go-to recipes that I haven't shared yet. They are not all that glamorous or exciting, but they are tried and true favourites that have been on rotation here for a long time. So stay tuned :)

It's hard to beat a slow cooker pot roast for being easy, one-pot and economical meal. Stewing beef roasts are a great deal when you spot them on sale! Snatch one up, add some potatoes and carrots and you're on your way to an easy, hearty and comforting meal.

I don't use my slow cooker a lot, but when it comes to pot roast, there is really is no easier way to do it. It takes only a short time to prepare all the ingredients and place them in to the slow cooker. Then just let it cook away for 6-8 hours and enjoy. There is nothing else to do, as your meat, veg and potatoes are all in the pot. For me, a loaf of fresh crusty bread is a must for this one, to soak up the plentiful gravy.

Everyone here loves this tomato gravy version, with tomato sauce complementing the beef juices as it cooks, with a little hit of vinegar to tang it up. It's simple and delicious.

Cook's Notes for Slow Cooker Tangy Tomato Pot Roast

For my photos here, I just spooned some of the gravy over-top, so as not to completely hide the ingredients. Rest assured there is plenty of tasty gravy with this one!

I find medium-sized yellow-fleshed potatoes work best here. Simply peel and slice in half lengthwise. For the carrots, I peel and halve, if they are thick, or if you have thinner, fresh carrots, you can leave them whole.

I like to remove the meat once tender to a cutting board, where I cut it in to smaller chunks. While I'm doing that, I stir in the bit of cornstarch to thicken the gravy. I will then return all the meat to the slow cooker to be coated in the thickened gravy, then serve from there.

Be sure to taste your gravy just before serving and season with additional salt and freshly ground pepper as needed.

I like to flip my roast over a couple of times while it's cooking if it's not fully submerged in the gravy, but it's not necessary, if you want to just set it and forget it.

No slow cooker? You can make this by simmering on the stovetop, covered or in a slow oven (325 F -ish) for 3-4 hours, or until the beef is fall-apart tender.
