This tasty slow cooker pepper steak cooks out to be packed with a ton of flavor and has simply amazing tender pieces of beef.

Slow Cooker Pepper Steak

Pepper steak is traditionally a dish that is stir-fried but surprisingly works pretty well in the slow cooker. It’s the perfect dinner dish that’s super easy to prepare and have cooking hours ahead of when you need it.

This slow cooker version of pepper steak features sliced bell peppers, slices of beef and thick slices of onion. This combination is all cooked in a sauce that has soy, tomatoes, beef stock, and a combination of other ingredients. To ensure the sauce is nice and thick, we make use of some cornstarch.

Pepper Steak Side Dishes

You can serve this dish with a ton of different sides, but for me, white rice is what I usually decide to cook. Alternatively, you can try using something like noodles, roast potatoes, mashed potatoes, fresh bread, and so much more.

Pepper Steak with Rice

The pepper steak is also an excellent topping on some roast potatoes or jacket potatoes. It’s an excellent way of feeding even more people from a single batch of this recipe.

Which Cut of Beef to use for Pepper Steak

As I mention in the handy cooking tips at the bottom of this page, it’s best to use a tough cut of beef. This choice of meat is because we will be cooking the beef for a long time. The beef will come out nice and tender at the end of cooking.

Tougher cuts of meat tend to be cheaper, so it’s a great way to save a bit of money. So try finding a cut such as chuck, round, brisket, or even beef shanks.

The leftovers of this dish are well worth keeping. You can simply store them in the fridge or freezer. You can use leftovers for lunch the next day or as part of a meal such as nachos. You could even use it as a filling for some tacos.

Cooking Tips

  • Between the beef bouillon and the soy sauce, you should have more than enough salt in this dish. With that said, you might find the need to adjust the seasoning at the end of cooking.
  • As with any beef dish for the slow cooker I highly recommend using a tough cut of meat for the best results as we will be cooking it for a long time.
  • If you like your bell peppers to be slightly crisp, then don’t add them at the start of cooking. At about, the 4-5 hour mark should be an excellent time to add them.
  • Browning the meat can be skipped if you’re running low on time or you don’t have access to anything that you can use to brown meat. (eg. a usable stove)

More Slow Cooker Recipes to Try

If you like this dish and will love to try out more beef recipes in the slow cooker, then you should certainly try out the Mongolian beef. It’s super easy, and the beef comes out to be so tender it just melts in the mouth. The sauce is slightly sweet and again is just so damn good.

The Mississippi roast is yet another great excellent recipe that you should try. It’s an exciting combination of  flavors but will have you going back for seconds, thirds, or even more.
