Ingredients for Crock Pot Pepper Steak
You only need a handful of simple ingredients to make this flavorful Crock Pot Pepper Steak. The combination of tender beef, colorful bell peppers, onions, tomatoes and savory seasonings creates a delicious sauce while everything slow cooks together.

- Beef sirloin – Use a whole piece of sirloin steak so you can sear it first, then slice it against the grain for tender, flavorful pieces.
- Garlic cloves - We’re slicing the garlic to give it enough aromatic flavor, but not overpowering it by mincing the garlic.
- Olive oil - Needed to help with searing the beef, giving it a nice brown crust on the outside.
- Montreal steak seasoning - A combination of herbs and spices typically meant for seasoning steak but you can use it on any protein.
- Water & cornstarch - We combine the two to make a cornstarch slurry. When mixed into the sauce it takes it from a runny liquid sauce to a thick rich gravy-like sauce.
- Beef broth - Adds a nice robust flavor to the sauce that pairs well with the seasoned beef.
- Onion - Sliced onions that have been cooked down deliver a natural sweetness and cuts down the pungency. They’re just so good!
- Sliced red bell peppers - Adds a beautiful pop of color to the dish. It’s also a yummy sweet veggie!
- Diced red tomatoes - Lends a bit of acid and tomato flavor to the sauce.
- Soy sauce - Savory umami elements come from adding soy sauce to anything!
- Sugar - Cuts the acid of the tomato and balances all the other flavors in the sauce.
- Salt & pepper - To taste.

How to Make Crock Pot Pepper Steak
Making Crock Pot Pepper Steak is easy. I recommend searing the beef before adding it to the slow cooker because that extra step gives the steak beautiful browned flavor.
Step 1: Season the beef


Pat the steak dry with paper towels. Season both sides generously with Montreal steak seasoning.
Step 2: Sear the steak
Heat olive oil in a large skillet over medium-high heat. Once the skillet is hot, add the steak and sear for about 2–3 minutes per side, or until nicely browned.
Transfer the steak to a cutting board and let it rest for a few minutes.
Step 3: Slice the steak
Slice the steak into strips against the grain. Cutting against the grain helps make the beef easier to chew and more tender when served.
Step 4: Prepare the cornstarch slurry


In a small bowl, whisk together the cornstarch and water until smooth and no lumps remain. Add cornstarch slurry to the slow cooker.
Step 5: Add everything to the slow cooker


Add the sliced beef, bell peppers, onion, garlic, diced tomatoes, beef broth, soy sauce, sugar, salt, and black pepper to the slow cooker.
Stir gently to combine.
Step 6: Slow cook


Cover and cook on HIGH for 3–4 hours or LOW for 6–8 hours, or until the beef is tender.
Step 7: Serve


Give the pepper steak a good stir and spoon it over steamed rice, creamy mashed potatoes or egg noodles. Make sure to spoon plenty of the savory sauce over the top!
Tips for Making the Best Crock Pot Pepper Steak

- Cut the beef against the grain. This is one of the easiest ways to get more tender bites of beef.
- Don't overcrowd the skillet. If your steak doesn't fit comfortably in one layer, sear it in batches. Overcrowding can cause the beef to steam instead of brown.
- Sear the beef first. It takes only a few extra minutes and adds so much flavor to the finished pepper steak.
- Use different colored peppers. Red, yellow, orange and green bell peppers all work. Mixing colors makes the finished dish extra pretty.
- Want firmer peppers? Add the bell peppers halfway through the cooking time so they retain more texture.
- Love extra sauce? Serve the pepper steak over rice, mashed potatoes or noodles so they can soak up all that delicious sauce.
What to Serve with Crock Pot Pepper Steak
This Crock Pot Pepper Steak makes plenty of flavorful sauce, so I love serving it with something that can soak up every last drop.
My favorite sides are:

My personal favorite? Cheesy mashed potatoes. The savory pepper steak sauce spooned over creamy potatoes is so good!

I made this tonight in my knock off instant pot. I sautéed the meat, added the garlic and 3/4 of a tin of petite diced tomatoes, beef broth, other seasoning and salt & pepper. Used pressure cook setting for 20 minutes and let it naturally release for 10, then quick released the rest. Thickened with tapioca flour (gluten free) and adjusted seasoning. I have a thing with mushy veggies, so I sautéed the peppers and onions on the side, served with white rice.
My husband almost cried he was so happy. It reminded him of what his mom cooked for his brothers birthday every year. The meat kept its shape while being amazingly tender.
Thanks for the recipe!!!
