How to Make Pepper Steak
-
Heat oil: Drizzle olive oil in a large skillet over medium-high heat. Allow it to warm before adding the sliced steak for about 2 to 3 minutes, searing until it’s nicely browned but still juicy inside.
-
Transfer to Crock Pot: Carefully place the seared steak into your slow cooker. Add the vibrant bell peppers, sliced onion, minced garlic, soy sauce, beef broth, Worcestershire sauce, black pepper, and optional red pepper flakes. Stir everything gently to ensure the flavors meld together beautifully.
-
Cook low and slow: Cover the Crock Pot and let it work its magic. Cook on low for 6 to 8 hours or choose high for a quicker 3 to 4 hours until the steak is fork-tender and the vegetables are perfectly cooked.
-
Thicken sauce: About 30 minutes before serving, whisk together the cornstarch and water until smooth. Stir this mixture into the Crock Pot and let it cook uncovered, allowing the sauce to thicken into a luscious coating for your Pepper Steak.
-
Serve boldly: Once everything is tender and the sauce has thickened, serve your Pepper Steak hot over a bed of steamed rice or noodles, soaking up all that delicious flavor.
Optional: Garnish with fresh parsley for a pop of color and added freshness.

Make Ahead Options
These Pepper Steak slow cooker delights are perfect for meal prep! You can slice the flank steak and vegetables (bell peppers, onion, and garlic) up to 24 hours in advance. Simply refrigerate them in an airtight container to maintain freshness and prevent browning. On the day you plan to serve, transfer the prepped ingredients to your Crock Pot, add the sauces and seasonings, and proceed with cooking as directed. The flavors will still meld beautifully! For even more convenience, you can prepare the cornstarch slurry the night before and store it in the fridge. Just remember to thicken the sauce shortly before serving for that irresistible finish!
Chef's Helpful Tips
- When preparing your Pepper Steak, thinly slicing the meat against the grain will ensure maximum tenderness.
- Remember to sear the steak in batches; overcrowding the pan can lead to steaming instead of browning, which hinders flavor development.
- For a more complex flavor, consider marinating the sliced steak in soy sauce and garlic for an hour before cooking.
- Keep an eye on the cooking time, as overcooking can make your steak tough; aim for a fork-tender texture by checking it a little earlier than the suggested times.
Pepper Steak Slow Cooker Recipe FAQs
How do I choose the best steak for this recipe?
Absolutely! For Pepper Steak, I recommend flank steak or sirloin as they are both flavorful and tender when sliced thinly. Look for cuts that have a good marbling of fat, as this will enhance the overall flavor and tenderness of your dish. Ensure that the meat is bright red and free from dark spots or excessive moisture for the best quality.
How do I store leftover Pepper Steak?
To keep your leftover Pepper Steak fresh, store it in an airtight container in the refrigerator. It will last for up to 3 days. When reheating, I suggest adding a splash of beef broth to keep the moisture in, preventing it from drying out.
Can I freeze Pepper Steak?
Absolutely! To freeze Pepper Steak, let it cool completely first, then transfer to a freezer-safe container or bag. It can be stored for up to 3 months. When you’re ready to enjoy it again, thaw it in the refrigerator overnight, and reheat on the stovetop over low heat, stirring occasionally until warmed through.
What should I do if my Pepper Steak sauce is too thin?
If your sauce isn’t thickening as desired, whisk together 1 tablespoon of cornstarch with 2 tablespoons of water to create a slurry and add it to the slow cooker. Stir it in, cover, and let it cook uncovered for an additional 15 to 20 minutes on high to help thicken up the sauce. Also, be sure to check the cooking time to ensure it has fully reduced.
Is this recipe friendly for people with dietary restrictions?
Yes! If you have issues with gluten, you can substitute tamari or coconut aminos for soy sauce, which are great alternatives that offer similar flavors. Additionally, be mindful of the Worcestershire sauce, as some brands contain anchovies. Look for a vegan version if you have a fish allergy. If you have pets, avoid sharing this meal as the soy sauce and certain spices might be harmful to them.
How can I adjust the spice level of my Pepper Steak?
The beauty of this Pepper Steak lies in its versatility! If you prefer a milder dish, skip the crushed red pepper flakes altogether. For a spicier kick, consider adding more red pepper flakes or a dash of hot sauce during the cooking process. Tasting along the way is key to achieving your desired heat level!
