Ingredients for Crock Pot Pepper Steak
Gathering these simple ingredients is the first step to pepper steak magic. I always make sure to have:

- 3/4 teaspoon garlic powder: For that essential savory base flavor
- 3 tablespoons vegetable oil: For searing the beef to golden perfection
- 1 beef bouillon cube + 1/4 cup hot water: Our flavor booster base
- 1 tablespoon cornstarch: Helps thicken that amazing sauce
- 1/2 cup chopped onion: I like yellow onions for sweetness
- 2 large green bell peppers: Roughly chopped (about 2 cups)
- 1 can (14.5 oz) stewed tomatoes: With all that flavorful liquid
- 3 tablespoons soy sauce: For that deep savory umami
- 1 teaspoon each white sugar and salt: To balance all the flavors
See? Nothing fancy, just good, honest ingredients that turn into something spectacular.
Equipment Youโll Need
Don’t worry, you won’t need any fancy gadgets for this recipe. Just grab these kitchen basics:

How to Make Crock Pot Pepper Steak
Now for the fun part, turning those simple ingredients into something amazing! Follow these steps, and you’ll have the most flavorful pepper steak ready when you walk in the door after a long day.
Step 1: Season and Sear the Beef
First, let’s give our beef that perfect flavor base. I sprinkle the sirloin strips with garlic powder and toss them gently; you want every piece to get a light coating. Then heat your oil in that skillet over medium heat (not too hot or the garlic powder might burn).
Working in batches is key here; don’t crowd the pan, or the beef will steam instead of sear. I give each batch about 5 minutes per side until they get those gorgeous brown edges. That caramelization equals big flavor for our finished dish!
Step 2: Prepare the Sauce Base
While the beef rests, let’s make our secret sauce starter. I take that beef bouillon cube and dissolve it in hot water, really stir it well so no chunks remain. Then I whisk in the cornstarch until it’s completely smooth. This little mixture is what gives our finished dish that perfect saucy consistency.
Pro tip: If you see any lumps, just keep whisking; they’ll disappear with a little patience.
Step 3: Combine Ingredients in Slow Cooker
Now the magic happens! I layer all those beautiful browned beef strips in the slow cooker first. Then comes the chopped onion and bell peppers. I love how the colors look together already. Next, the whole can of stewed tomatoes goes in (liquid and all, that’s flavor gold!).
Finally, I pour over our prepared sauce base, soy sauce, sugar, and salt. A gentle stir to combine everything, but don’t go crazy; we want to keep those beef pieces intact.
Step 4: Slow Cook to Perfection
Here’s where patience pays off! For a quicker meal, I set it on High for 3-4 hours. But if I’ve got time, the Low setting for 6-8 hours makes the beef so tender it practically melts.
You’ll know it’s done when the beef shreds easily with a fork, and the peppers are soft but still bright. That first bite will have you doing a happy dance, I promise!

Tips for the Best Crock Pot Pepper Steak
After making this recipe more times than I can count, I’ve picked up some tricks that take it from good to “wow!” Here are my can’t-live-without tips:
- Deglaze that skillet! After searing the beef, pour a splash of water or broth into the hot pan and scrape up all those tasty browned bits. Add this liquid gold to your slow cooker; it’s pure flavor.
- Wait to salt: I always taste before adding the full teaspoon of salt at the end. Soy sauce adds saltiness, and tomatoes vary too.
- Cut against the grain: When slicing your beef strips, look for those muscle lines and cut across them. This makes every bite extra tender.
- Fresh pepper magic: If you’ve got time, sautรฉ the peppers and onions briefly before adding. It brings out their sweetness.
- Thicken it up: For a richer sauce, mix 1 tablespoon cornstarch with 2 tablespoons cold water and stir it in during the last 30 minutes.
These little touches make all the difference between “just dinner” and “can I have seconds?”
Serving Suggestions for Crock Pot Pepper Steak
Now for my favorite part, loading up my plate with all that delicious pepper steak goodness! Over the years, I’ve found so many tasty ways to serve this dish. My absolute go-to is a big scoop of steaming white rice; it soaks up that amazing sauce like a dream.
But don’t stop there! Try it over egg noodles for a comforting twist, or with mashed potatoes when you want something extra cozy. For nights when I’m feeling fancy, I’ll toast some crusty bread to mop up every last drop. A sprinkle of chopped green onions or sesame seeds on top adds the perfect fresh crunch.
Sometimes I’ll even serve it in bowls with extra veggies for a low-carb option. However you dish it up, just be ready for compliments!
Storing and Reheating Leftovers
If you’re lucky enough to have leftovers (I rarely do!), here’s how to keep them tasting amazing. I transfer any extra pepper steak to airtight containers and pop them in the fridge within two hours of cooking. It stays fresh for 3-4 days this way.
For longer storage, freeze portions in freezer-safe bags or containers; they’ll keep for about 2 months. When reheating, my favorite method is on the stovetop over medium-low heat with a splash of water to bring the sauce back to life. In a pinch, the microwave works too, just cover and heat in 1-minute bursts, stirring between each to prevent hot spots.
Pro tip: The flavors actually improve overnight, making leftovers something to look forward to!
Crock Pot Pepper Steak Variations
One of my favorite things about this recipe is how easily you can mix it up depending on what’s in your fridge or pantry. Last week I swapped the green peppers for red and yellow ones; the extra sweetness was incredible! If you’re feeling adventurous, try adding a tablespoon of Worcestershire sauce for deeper umami flavor.
My cousin swears by tossing in some sliced mushrooms during the last hour of cooking. And for a little heat, a teaspoon of red pepper flakes or a diced jalapeรฑo works magic. The basic recipe is perfect as is, but don’t be afraid to make it your own!

FAQs About Crock Pot Pepper Steak
Can I use frozen beef for pepper steak?
Absolutely! Just thaw it completely first so it sears properly. I’ve made this with frozen beef that I thawed overnight in the fridge, and it worked beautifully. The key is patting it very dry before seasoning and searing.
How can I thicken the sauce if it’s too thin?
My go-to trick is mixing 1 tablespoon of cornstarch with 2 tablespoons of cold water, then stirring it into the slow cooker during the last 30 minutes of cooking. If you’re in a real hurry, you can also transfer some liquid to a saucepan and simmer it on the stove until reduced.
What cut of beef works best?
While I love sirloin for its balance of tenderness and flavor, flank steak or chuck roast works great too. Just remember to slice against the grain, no matter what cut you choose!
Can I make this without soy sauce?
Yes! Try coconut aminos for a soy-free version, or just leave it out and add an extra pinch of salt. The tomatoes and bouillon still give plenty of savory flavor.
Why sear the beef first?
Trust me, those few extra minutes make all the difference! Searing locks in juices and creates delicious browned bits that add incredible depth to the finished dish. It’s worth every second.

- Yield: 6 servings 1x
- Diet: Low Lactose
Description
This Crock Pot Pepper Steak is a set it and forget it meal with tender strips of beef, bell peppers, and a savory tomato soy sauce. It is great served over rice, noodles, or mashed potatoes for an easy family dinner.
Ingredients
- 2 pounds beef sirloin, cut into 2 inch strips
- 3/4 teaspoon garlic powder
- 3 tablespoons vegetable oil
- 1 beef bouillon cube
- 1/4 cup hot water
- 1 tablespoon cornstarch
- 1/2 cup chopped onion
- 2 large green bell peppers, roughly chopped
- 1 can stewed tomatoes with liquid (14.5 oz)
- 3 tablespoons soy sauce
- 1 teaspoon white sugar
- 1 teaspoon salt, to taste
Instructions
- Season the beef: Sprinkle the beef sirloin strips with garlic powder, tossing so that all sides are lightly coated.
- Sear the beef: Heat the vegetable oil in a large skillet over medium heat. Add the beef strips in a single layer and sear for about 5 minutes per side, until nicely browned. You can do this in batches if needed. Transfer the browned beef into the slow cooker.
- Make the sauce base: In a small bowl, dissolve the beef bouillon cube in the hot water. Stir in the cornstarch until the mixture is smooth with no lumps.
- Load the slow cooker: Pour the bouillon and cornstarch mixture over the beef in the slow cooker. Add the chopped onion, green bell peppers, stewed tomatoes with their liquid, soy sauce, sugar, and salt. Stir gently to mix everything together.
- Slow cook: Cover the slow cooker. Cook on High for 3 to 4 hours, or on Low for 6 to 8 hours, until the beef is tender and the peppers are soft. The longer Low setting will give the most tender meat and richer flavor.
- Serve: Give everything a good stir, then taste and adjust the seasoning with a little more salt or soy sauce if needed. Serve the pepper steak hot over cooked rice, noodles, or with crusty bread to soak up the sauce.
Notes
- Add a splash of red wine or a dash of Worcestershire sauce for extra depth.
- Use red or yellow bell peppers for sweeter flavor and more color.
- For a thicker sauce, remove the lid during the last 30 minutes of cooking so some liquid can evaporate.
