- 2 large green bell peppers, seeded and sliced into 1/2-inch strips
- 1 large red bell pepper, seeded and sliced into 1/2-inch strips
- 1 large yellow onion, halved and sliced into thin half-moons
- 3 cloves garlic, minced
- 1 inch fresh ginger, grated (optional, but highly recommended)
- 1 cup low-sodium teriyaki sauce
- 1/2 cup beef broth (or water)
- 2 tablespoons soy sauce (low sodium preferred)
- 1 tablespoon brown sugar (optional, for extra sweetness)
- 1 teaspoon sesame oil (optional, for extra flavor)
- 1/2 teaspoon black pepper
- 1/4 cup cornstarch
- 1/4 cup cold water
- Cooked white rice or noodles, for serving
- Sesame seeds, for garnish (optional)
- Sliced green onions, for garnish (optional)
Instructions
- Prepare the beef: Thinly slice the flank steak (or chosen beef cut) against the grain into 2-3 inch long strips. This helps ensure tenderness.
- Prepare the vegetables: Seed and slice the green and red bell peppers into 1/2-inch strips. Halve the yellow onion and slice it into thin half-moons. Mince the garlic and grate the fresh ginger, if using.
- Layer ingredients in the slow cooker: Place the sliced beef evenly on the bottom of your 6-quart (or larger) slow cooker.
- Add vegetables: Scatter the sliced green bell peppers, red bell peppers, and yellow onion over the beef. Add the minced garlic and grated ginger (if using) on top.
- Prepare the sauce: In a medium bowl, whisk together the teriyaki sauce, beef broth, soy sauce, brown sugar (if using), sesame oil (if using), and black pepper until well combined.
- Pour sauce over ingredients: Carefully pour the sauce mixture evenly over the beef and vegetables in the slow cooker. Do not stir.
- Cook: Cover the slow cooker with the lid. Cook on LOW for 6-8 hours or on HIGH for 3-4 hours, or until the beef is tender and the vegetables are cooked through.
- Thicken the sauce (last 30 minutes): About 30 minutes before serving, in a small bowl, whisk together the cornstarch and cold water until a smooth slurry forms.
- Stir in slurry: Carefully remove the lid from the slow cooker. Stir the cornstarch slurry into the sauce in the slow cooker. Stir gently to incorporate.
- Continue cooking: Replace the lid and continue to cook on HIGH for another 20-30 minutes, or until the sauce has thickened to your desired consistency.
- Serve: Taste and adjust seasonings if needed. Serve the Crockpot Pepper Steak hot over a bed of fluffy white rice or noodles. Garnish with sesame seeds and sliced green onions, if desired.
Cooking Tips and Variations
To ensure your Crockpot Pepper Steak is the best it can be, consider these tips. For ultimate beef tenderness, always slice your meat against the grain. This shortens the muscle fibers, making the beef easier to chew after slow cooking. While the recipe suggests adding all ingredients at once for simplicity, if you prefer your bell peppers with a bit more bite and less softness, you can add them during the last 1-2 hours of cooking on high, or the last 30-60 minutes on low. This prevents them from becoming too mushy. Browning the beef before adding it to the slow cooker is an optional step that can add an extra layer of depth and flavor through the Maillard reaction. Simply sear the sliced beef in a hot pan with a little oil for a few minutes until browned on all sides before placing it in the crockpot. This isn’t necessary for tenderness but enhances the overall taste. When thickening the sauce with a cornstarch slurry, always mix the cornstarch with cold water first. Adding cornstarch directly to hot liquid can cause it to clump. Stir the slurry into the slow cooker and allow it to cook for at least 20 minutes for the starch to fully activate and thicken the sauce without a starchy taste.
Don’t be afraid to customize this recipe to your liking with these delicious variations. For a spicy kick, add 1/2 teaspoon of red pepper flakes to the sauce mixture, or offer sriracha at the table for individual preference. If you enjoy a sweeter, more Hawaiian-inspired flavor, consider adding 1/2 cup of canned pineapple chunks (drained) along with the bell peppers. This adds a lovely sweet and sour note. While flank steak is traditional, you can experiment with other cuts of beef such as stew meat (cut into strips), sirloin, or even beef chuck, though cooking times might vary slightly for tougher cuts. Beyond bell peppers and onions, feel free to incorporate other vegetables that stand up well to slow cooking. Sliced mushrooms, shredded carrots, or even snow peas (added at the very end to maintain their crispness) would make excellent additions. For a different flavor profile, you could swap out the teriyaki sauce for a homemade blend of soy sauce, ginger, garlic, a touch of honey, and rice vinegar for a more traditional Asian-inspired sauce. For a richer, darker sauce, a splash of Worcestershire sauce can be added to the sauce mixture.
Storage and Reheating
Storing your Crockpot Pepper Steak correctly ensures that you can enjoy delicious leftovers for days. Once cooled, transfer the pepper steak and its sauce to airtight containers. It will keep beautifully in the refrigerator for up to 3-4 days. For longer storage, Crockpot Pepper Steak freezes exceptionally well. Place cooled portions into freezer-safe containers or heavy-duty freezer bags. It can be stored in the freezer for up to 2-3 months. When reheating from frozen, it’s best to thaw it overnight in the refrigerator first.
To reheat, you have a few excellent options. The microwave is the quickest method for individual portions. Simply place the pepper steak and sauce in a microwave-safe dish, cover loosely, and heat on medium power for 2-3 minutes, stirring halfway through, until heated through. For larger portions or to retain moisture, reheat on the stovetop. Transfer the pepper steak and sauce to a saucepan or skillet over medium-low heat. Stir occasionally until warmed through, adding a splash of beef broth or water if the sauce seems too thick. You can also reheat it in the oven for a more even warmth, especially if reheating a larger batch. Place the pepper steak in an oven-safe dish, cover with foil, and bake at 300°F (150°C) for 20-30 minutes, or until thoroughly heated. No matter the method, ensure the internal temperature reaches 165°F (74°C) for safe consumption. This dish reheats wonderfully, often tasting even better the next day as the flavors have more time to deepen and meld.
Frequently Asked Questions
What kind of beef is best for Crockpot Pepper Steak?
Flank steak, sirloin steak, or round steak are excellent choices for Crockpot Pepper Steak. They are lean cuts that become wonderfully tender when slow-cooked. You can also use pre-cut stir-fry beef strips for convenience. If you use a tougher cut like stew meat, ensure it’s sliced thinly to allow for proper tenderizing within the cooking time.
Do I need to brown the beef before putting it in the slow cooker?
Browning the beef is entirely optional for Crockpot Pepper Steak. While it adds a deeper, richer flavor through caramelization, it’s not strictly necessary for tenderness or doneness with slow cooking. If you’re short on time, you can skip this step and still achieve a delicious meal. If you do choose to brown, sear the beef in a hot skillet for a few minutes until lightly browned before adding it to the slow cooker.
How can I prevent my peppers from getting too mushy?
To keep your bell peppers from becoming overly soft or mushy, you can add them later in the cooking process. If cooking on LOW, add them during the last 1 to 1.5 hours. If cooking on HIGH, add them during the final 30-45 minutes. This allows them to cook through and become tender-crisp without losing their vibrant color and texture.
Can I make this recipe gluten-free?
Yes, you can easily adapt this Crockpot Pepper Steak recipe to be gluten-free. Simply ensure that you use a gluten-free teriyaki sauce and a gluten-free soy sauce (such as tamari). All other ingredients in the recipe are typically naturally gluten-free, but always double-check labels, especially for broths and seasonings, to confirm they don’t contain hidden gluten.
