• Large mixing bowl or measuring glass for the sauce
• Whisk or fork for stirring
• Sharp knife and cutting board
• Ladle or large spoon for serving

Step-by-Step Instructions

Making this Crock Pot Pepper Steak is genuinely one of the easiest dinners you can pull off. Here’s exactly how to do it.

Step 1 — Make the Sauce

In a large mixing glass or bowl, combine the hot beef broth and 3 beef bouillon cubes. Stir well, crushing the cubes until fully dissolved.

Add the soy sauce, Worcestershire sauce, honey, ground ginger, black pepper, salt, and cornstarch (or flour) to the broth mixture. Stir everything together until smooth and well combined — your sauce should smell amazing already.

Step 2 — Layer the Slow Cooker

Place the 2 lbs of beef sirloin strips into the bottom of your slow cooker in an even layer. Pour the sauce you just made directly over the beef, making sure every piece gets coated.

Next, layer the thick-sliced bell peppers, sliced onion, and whole or minced garlic cloves right on top of the beef and sauce. No need to stir yet — the layers will meld beautifully as they cook.

Step 3 — Set It and (Almost) Forget It

Place the lid on your slow cooker. Set it to LOW for 6 hours or HIGH for 3 hours. If you can, give everything a gentle stir at the halfway point to help the flavors distribute evenly.

Your kitchen is going to smell absolutely incredible. Fair warning: everyone in the house will start asking what’s for dinner approximately 30 minutes in.

Step 4 — Serve and Enjoy

Once cooking is complete, give everything a good stir. The beef should be tender and the sauce should have thickened into a glossy, flavorful coating around the peppers and meat.

Transfer to a serving dish and spoon generously over cooked white rice, egg noodles, mashed potatoes, or baked potatoes. Every option is a winner here.

Pro Tips for Perfect Crockpot Beef and Peppers

Slow cooker beef and peppers is pretty forgiving, but these tips will take yours from good to absolutely incredible.

Slice your beef against the grain. This is the single biggest trick for getting melt-in-your-mouth tenderness. Look at the direction of the muscle fibers in your sirloin and cut perpendicular to them. Even a few extra seconds of attention here makes a huge difference in the final texture.

Use HOT broth for the sauce. Hot liquid is key for properly dissolving the bouillon cubes. Cold or room-temperature broth won’t fully break them down and you’ll end up with uneven seasoning throughout your dish. Pop it in the microwave for 60 seconds if needed.

Slice your peppers thick. Thin-sliced peppers will turn to mush after 6 hours on LOW. Aim for strips about 1/2 inch to 3/4 inch wide so they hold their shape and add a satisfying bite to the finished dish.

Don’t skip the halfway stir if you can help it. It’s not required, but if you’re home, a quick stir at the 3-hour mark on LOW ensures the sauce coats everything evenly and prevents any sticking along the edges.

Quick Fixes for Crock Pot Pepper Steak

The sauce is too thin. Mix 1 tablespoon of cornstarch with 2 tablespoons of cold water until smooth. Stir the slurry into the slow cooker, replace the lid, and cook on HIGH for another 20–30 minutes. The sauce will thicken up nicely.

The beef feels tough. It likely needs more time. Tough beef in the slow cooker is almost always a sign it hasn’t fully broken down yet. Add 30–60 more minutes on LOW and check again — it’ll get there.

It tastes too salty. Stir in a small drizzle of extra honey or a splash of plain water to balance things out. You can also add a squeeze of fresh lemon juice, which cuts through saltiness without changing the overall flavor profile.

The peppers are too soft. For firmer peppers next time, add them during the last 1.5–2 hours of cooking instead of at the beginning. They’ll still absorb the sauce flavors but keep a bit more texture.

The flavor feels flat. A splash more of soy sauce or Worcestershire at the end of cooking can wake everything up. Taste and adjust before serving — this is your dish, make it yours.

Variations and Adaptations

This slow cooker beef and peppers recipe is incredibly easy to customize depending on what you have on hand or what your family loves.

Gluten-free: Swap the soy sauce for tamari or coconut aminos, and use cornstarch instead of flour to thicken the sauce. Everything else is naturally gluten-free — easy swap, same great flavor.

Lower sodium: Use low-sodium beef broth, low-sodium soy sauce, and reduce the bouillon cubes to 2 instead of 3. Taste and adjust at the end rather than seasoning heavily at the start.

Add mushrooms: Slice up a cup of cremini or baby bella mushrooms and add them with the peppers. They soak up all that savory sauce and add a lovely earthy depth.

Spicy version: Stir in a teaspoon of red pepper flakes or a splash of sriracha to the sauce mixture before pouring it over the beef. Totally optional but so good if you like a little kick.

Swap the protein: Chicken thighs work beautifully in this recipe with the same sauce — reduce cooking time to LOW for 4–5 hours.

Serving, Storage, and Reheating

This crockpot meals with bell peppers classic is best served hot and fresh, spooned generously over rice, egg noodles, or creamy mashed potatoes. A sprinkle of sesame seeds or sliced green onions on top makes it look extra gorgeous with zero extra effort.

Store any leftovers in an airtight container in the refrigerator for up to 3–4 days. The flavor actually deepens overnight, so your next-day lunch is going to be even better than dinner was. If you make a big batch, this freezes well too — up to 3 months in a freezer-safe bag or container.

To reheat, warm it gently in a saucepan over medium-low heat with a small splash of beef broth to loosen the sauce. You can also microwave in 60-second intervals, stirring between each, until heated through. Avoid reheating on high heat — it can make the beef tough.

Looking for more cozy make-ahead ideas? These copycat cheeseburger sliders are another crowd-pleasing dinner that’s just as easy to pull together.

No-Waste Kitchen Magic

If you have leftover Crock Pot Pepper Steak sauce in the bottom of the slow cooker, don’t rinse it down the drain. Spoon it over scrambled eggs in the morning — sounds wild, tastes incredible.

Leftover beef and peppers make an excellent filling for next-day quesadillas or grain bowls. Lay them over a base of farro or brown rice with some greens and you’ve got lunch sorted without cooking a single thing.

Got wilted bell peppers sitting in the fridge? This is the perfect recipe to use them up before they turn. The slow cooker fully revives them into something delicious, so no fresh-from-the-farmers-market peppers required.
