Ingredients for Slow Cooker Pepper Steak

Before you get started, let’s gather everything you’ll need to make this flavor-packed slow cooker pepper steak. The beauty of this dish is how simple it is — just a few everyday ingredients come together to create a rich, savory sauce and incredibly tender beef.

Here’s what to have on hand:

 Main Ingredients

• 1.5 to 2 pounds flank steak – sliced into thin strips; you can also use sirloin or top round for a leaner option
• 2 bell peppers – any color works, but red and green add a nice flavor balance
• 1 medium onion – sliced thin; yellow or white both work well
• 2 cloves garlic – minced, for that deep savory base

 For the Sauce

• 1/3 cup low-sodium soy sauce – gives that umami-rich base without overpowering saltiness
• 1/4 cup beef broth – adds depth and keeps everything moist while cooking
• 1 tablespoon brown sugar – a hint of sweetness to balance the savory notes
• 1 tablespoon cornstarch – helps thicken the sauce into that glossy, silky texture
• 1 tablespoon olive oil – optional, but great if you’re browning the beef before slow cooking

 Optional Add-Ins

• Crushed red pepper flakes – for a touch of heat
• 1 tablespoon hoisin sauce – adds extra richness and depth
• 1 teaspoon ginger (fresh or ground) – brightens the dish with a gentle zing

 Ingredient Tips:

• Slice meat thinly and against the grain to ensure tenderness — this makes all the difference in every bite.
• Use fresh bell peppers for the best texture. Frozen can work in a pinch but will soften more during the slow cook.
• Want to cut down on sugar? Swap brown sugar with a sugar-free alternative like monk fruit or omit it for a more savory profile.

With your ingredients prepped and ready, you’re just steps away from an incredibly satisfying slow cooker meal that delivers big flavor with minimal effort.

How to Make Slow Cooker Pepper Steak

Making this slow cooker pepper steak is incredibly easy — you don’t need fancy skills or a long prep list. It’s a “set it and forget it” kind of dish that rewards you with tender beef, vibrant peppers, and a deeply savory sauce by dinnertime.

Here’s a step-by-step guide to walk you through it:

1. Prep Your Ingredients

Start by slicing your flank steak thinly against the grain — this helps keep the meat tender as it cooks.
Chop your bell peppers and onion into thin strips and mince the garlic.

 Tip: Try to keep the slices uniform for even cooking.

 2. (Optional) Sear the Beef for Extra Flavor

If you have a few extra minutes, heat olive oil in a skillet over medium-high heat and quickly brown the beef on both sides.

• This step adds a deep, caramelized flavor to the dish.
• It’s totally optional — skip it if you’re short on time.

 3. Make the Sauce

In a bowl, whisk together:

• Low-sodium soy sauce
• Beef broth
• Brown sugar
• Minced garlic
• Optional: a dash of hoisin sauce or a sprinkle of ginger for more depth

 4. Layer It All in the Slow Cooker

Add the sliced beef, onions, and peppers to your slow cooker.
Pour the sauce over the top, making sure everything is coated well.

 You don’t need to stir — the magic happens as it simmers.

 5. Cook Low and Slow

• Low setting: 5–6 hours (for maximum tenderness)
• High setting: 3–4 hours (if you’re short on time)

Your kitchen will smell amazing as it cooks — just try to resist sneaking a bite!

 6. Thicken the Sauce

About 20–30 minutes before serving:

• Mix 1 tablespoon cornstarch with 2 tablespoons water to make a slurry.
• Stir it into the slow cooker to thicken the sauce into that luscious, takeout-style glaze.

 7. Serve and Enjoy

Once the sauce is thickened and the beef is fork-tender, it’s ready to serve.
Pair it with steamed rice, noodles, or a low-carb side like cauliflower rice for a comforting and complete meal.

Making crockpot pepper steak is as easy as it is rewarding. With just a little prep and a lot of flavor payoff, this recipe is sure to become a staple in your home kitchen.

Want to elevate your slow cooker pepper steak to the next level? Here are some tried-and-true tips and tasty variations to help you get the most flavor and enjoyment from this easy, comforting dish.

 Pro Tips for Perfect Slow Cooker Pepper Steak

• Slice the Steak Against the Grain
  Cutting the beef thinly against the grain ensures it stays tender and easy to chew after hours in the slow cooker.
• Don’t Skip Browning (If Possible)
  Quickly searing the steak before slow cooking adds a deeper, richer flavor. If you’re short on time, this step is optional, but highly recommended.
• Add Bell Peppers Later for a Firmer Texture
  If you prefer your peppers with a bit of crunch, add them in the last hour of cooking instead of at the start.
• Use a Cornstarch Slurry to Thicken the Sauce
  Mix cornstarch with cold water and stir it into the sauce near the end of cooking for a glossy, thickened finish that clings beautifully to the beef.
• Choose Fresh Ingredients for Best Flavor
  Fresh bell peppers and garlic will always deliver more vibrant taste compared to frozen or pre-minced options.

 Delicious Variations to Customize Your Meal

• Spice It Up
  Add crushed red pepper flakes or a dash of hot sauce for a spicy kick that wakes up the dish.
• Low-Carb Friendly
  Serve over cauliflower rice or sautéed greens to keep things light and keto-friendly.

  Try chicken thighs or pork strips for a different but equally delicious slow cooker meal.
