I’ve been making pepper steak for years.  I used to make it on the stove, but I created this Slow Cooker Pepper Steak to make life a little easier. 

You get all the great flavors of pepper steak, tender beef, bell pepper, tomatoes, and onion, in a rich and savory sauce, but it’s conveniently made in the slow cooker!

I’ve experimented with this pepper steak recipe many times and loved it, but when I took a page from some of my favorite Peruvian/Argentinian dishes by adding some red wine vinegar to the recipe, it went from good to AMAZING!

What is Pepper Steak?

Pepper Steak is an Asian-inspired meal consisting of sliced beef, onions, garlic, and peppers in a beefy tomato/soy sauce.

It’s a meal that most people are familiar with, yet if 10 different people made it, it would turn out 10 different ways.

Everyone has their idea of what pepper steak should be and while it has some traditional elements that make it what it is, it’s very adaptable to personal preference. 

I’ve had pepper steak that didn’t have any ginger at all.  I’ve had a very tomatoey pepper steak (not my husband’s favorite), and I’ve also eaten it with various cuts of meat. 

I happen to like them all, so I combined everything I love about pepper steak into this wonderful, easy-to-make, slow cooker version that’s perfect for busy weeknights.

Ingredients needed for this recipe (scroll down to recipe card for complete recipe):

• Bell peppers 
• Onion
• Garlic 
• Round steak
• Flour
• Tomatoes
• Ginger – ginger paste or grated fresh ginger
• Soy sauce
• Red wine vinegar
• Worcestershire sauce
• Seasonings – sea salt, black pepper, white pepper, bay leaf

How to make Slow Cooker Pepper Steak:

1. Slice your meat and toss it around in some all-purpose flour and then throw it in the slow cooker with onion, garlic, ginger, red and green bell peppers, tomatoes, spices, and liquids. 
2. I like to cook this on high for 3 hours or low for 6 hours, but if you want to help keep the texture of the peppers more firm, add the bell peppers in the last hour.  
3. Regardless of which method you use, you’ll have strips of super tender meat swimming in a bath of delicious juices from soy sauce, red wine vinegar, Worcestershire sauce, garlic, and ginger that’s just screaming to be absorbed by your favorite starchy side.

What type of beef is good for Slow Cooker Pepper Steak?

I typically use round steak or London broil for this recipe because you want a cut of steak that is going to hold its shape and not fall apart like chuck roast. 

Sirloin steak is delicious and very tender, but too expensive for a slow cooker meal.

Do I have to brown the meat first?

This recipe has been tested by coating the meat in flour and browning it in a pan, and also by just coating the meat in flour and throwing it right in the slow cooker. 

Each version was really good, but I didn’t notice a big difference in flavor from browning the meat, so I started skipping that extra step and it still turns out fantastic each time!

The flour acts as a sauce thickener, so I wouldn’t skip that step.

How to serve pepper steak

Pepper steak is delicious served with something to absorb all the delish sauce!  Some of our favorites are:

• Rice – white rice, Herbed Butter Garlic Rice, brown rice, cauliflower rice
• Mashed potatoes
• Egg noodles

How long is pepper steak good for?

Leftovers can be refrigerated in an air-tight container for 3-4 days.

You can, technically, freeze pepper steak, but the texture of the peppers will be less than ideal when reheated.

💡Tips & Tricks

• If you love bell peppers, feel free to add yellow or orange bell peppers to the red and green ones.
• If you want to keep the texture of the peppers more firm, add them at the last hour of cooking.
