Black Pepper: Don’t be shy—it brings a gentle, savory heat that rounds out the flavor.

How to Make Slow Cooker Pepper Steak Recipe

Step 1: Mix Up the Flavor-Packed Sauce

Start by grabbing a mixing glass or medium bowl and combine hot beef broth, crumbled bouillon cubes, soy sauce, Worcestershire sauce, honey, ground ginger, black pepper, salt, and cornstarch or flour. Stir it all together until the bouillon cubes dissolve and you have a smooth, rich liquid. This is where those incredible flavors start to marry, so take a moment to appreciate that savory aroma—it’s a preview of what’s to come!

Step 2: Layer in the Beef and Sauce

Lay your sirloin strips gently at the bottom of your slow cooker. Pour the finished sauce right over top, making sure every piece of meat gets coated. Don’t worry if things look a bit sparse with the liquid at this point—trust the process. As it cooks, the beef and vegetables will release plenty of juices for a lush, hearty sauce.

Step 3: Add the Peppers, Onions, and Garlic

Scatter those vibrant pepper slices, onions, and garlic cloves across the top of your beef. This not only creates a burst of color but lets the veggies become irresistibly tender and flavorful as they soak up the sauce and juices from the beef. The slow cooker will do all the heavy lifting, coaxing out the sweetness and melding all the flavors together.

Step 4: Let the Slow Cooker Do Its Magic

Place the lid on your slow cooker and set it to LOW for six hours (or HIGH for three hours if you’re pressed for time). If you’re around, give everything a good stir halfway through to help the flavors play together even more. As the hours pass, the irresistible aroma of this Slow Cooker Pepper Steak Recipe will have everyone peeking into the kitchen, asking what’s cooking!

Step 5: Finishing Touches and Serve

When the cooking time is up and the beef is meltingly tender, stir everything one last time. Transfer the pepper steak to a serving dish and get ready to bask in the oohs and aahs from your lucky diners. Spoon over rice, noodles, or even mashed potatoes, and let every last drop of saucy goodness find its way onto your plate.

How to Serve Slow Cooker Pepper Steak Recipe

Garnishes

Dress up your Slow Cooker Pepper Steak Recipe with a sprinkle of freshly sliced green onions, a handful of chopped cilantro, or even a little toasted sesame seed for a satisfying crunch. A few chili flakes or a twist of freshly cracked black pepper add both flair and a little bit of kick if you’re in the mood. A bright squeeze of lime can wake up all those savory flavors, too!

Side Dishes

This dish was made for soaking up sauce, so serve it over fluffy steamed rice or buttery mashed potatoes. Egg noodles are another cozy, classic option, turning your slow cooker masterpiece into a heartwarming bowl. For a lighter touch, try it with cauliflower rice or steamed broccoli on the side to round out the meal with something fresh and green.

Creative Ways to Present

If you’re feeling playful, try stuffing the pepper steak mixture inside toasted hoagie rolls for a spectacular sandwich. It also works wonderfully as a filling for lettuce wraps for a lighter, hand-held version. For a fun twist, top a baked potato with a generous spoonful of slow-cooked pepper steak and a dollop of sour cream. The possibilities are as delicious as they are endless!

Make Ahead and Storage

Storing Leftovers

Leftovers of this Slow Cooker Pepper Steak Recipe keep like a dream. Just let everything cool to room temperature, then transfer to airtight containers and store in the fridge for up to four days. The flavors deepen overnight, making those second helpings even better!

Freezing

If you want to get ahead for busy weeks, simply portion the cooled pepper steak into freezer-safe bags or containers. Lay them flat for quicker thawing, and they’ll keep beautifully in the freezer for up to three months. When the craving strikes, it’ll be ready and waiting for you.

Reheating

To reheat, use the microwave for quick portions or gently warm on the stovetop over low heat, adding a splash of beef broth if the sauce needs loosening. If reheating from frozen, let it thaw overnight in the fridge first. Stir as you go to make sure everything heats through evenly, and you’ll be right back in comfort-food heaven.

FAQs

Can I use a different cut of beef?

Absolutely! While sirloin is wonderfully tender, you can also try flank steak, round steak, or even chuck if you’re after that classic slow-cooked texture. Just make sure to slice against the grain for maximum tenderness.

Can I make this recipe gluten free?

You sure can! Swap out regular soy sauce for a gluten-free variety (like tamari) and use cornstarch rather than flour as your thickener. Always double-check that your bouillon cubes are gluten free as well.

Can I add more vegetables?

Definitely! Mushrooms, snap peas, or even baby corn are fabulous candidates to bulk up your Slow Cooker Pepper Steak Recipe. Just keep in mind that adding extra veggies will create more juices, so consider increasing your thickener if you prefer a more robust sauce.

What if I don’t have a slow cooker?

If you don’t own a slow cooker, you can adapt this recipe to a Dutch oven or a heavy-bottomed pot in your oven. Cook it covered at a low temperature (around 300°F) for about 2-3 hours, checking occasionally for tenderness and sauce level.

Why does the sauce look so watery at first?

It’s totally normal! The beef and vegetables will release their natural juices as they cook, creating plenty of rich sauce by the end. Give everything a good stir before serving and you’ll have that perfect, glossy finish.
