Ingredients

For the beef & vegetables
- Flank steak – Cooks quickly and stays tender when sliced properly. Slice into bite-sized pieces
- Small onion – Adds natural sweetness and flavor as it cooks
- Red bell pepper – Slightly sweet and adds color to the dish. You can also add in yellow bell peppers.
- Green bell pepper – More savory flavor that balances the sweetness of the sauce
- Minced garlic – Adds bold flavor—jarred garlic works great for convenience
- Cooking oil (avocado, vegetable, or sesame) – Helps sear the meat and vegetables (use what you have on hand)
- Black pepper – Simple seasoning that enhances the beef
- Ground ginger – Adds a mild, warm flavor to the dish
For the sauce
- Soy sauce – The base of the sauce, adding salty, savory flavor
- Sugar – Balances the saltiness and creates that takeout-style taste
- Cold water – Helps thin the sauce so it coats everything evenly
- Cornstarch – Thickens the sauce into a glossy glaze
For serving
- Cooked white rice – A budget-friendly way to stretch the meal

How to Make Blackstone Pepper Steak

Step 1 – Preheat the Blackstone to medium-high heat (about 400°F) and add 1 tbsp cooking oil to lightly coat the surface.

Step 2 – Add 1 small sliced onion, 1 sliced red bell pepper, and 1 sliced green bell pepper to the flat top grill. Cook for 2–3 minutes, stirring occasionally until slightly tender. Move them to the cooler side of the griddle.

Step 3 – Spread 1½ lbs thinly sliced flank steak on the hot side of the griddle in a single layer. Season with ½ tsp black pepper and ¼ tsp ground ginger. Cook for 2–3 minutes, flipping occasionally until browned.

Step 4 – Move the vegetables back with the steak. Add 2 tsp minced garlic and cook for about 30 seconds, stirring until fragrant.

Step 5 – In a small bowl, whisk together ½ cup soy sauce, 2 tbsp sugar, ¼ cup cold water, and 2 tbsp cornstarch until smooth.

Step 6 – Pour the savory sauce over the steak and vegetables. Stir the mixture together and cook for 1–2 minutes until the sauce thickens and coats the meat.
Step 7 – Serve hot over cooked white rice if desired and garnish with sesame seeds or sliced green onions. Enjoy!

Tips for Success
- Slice the steak thin and against the grain for best results. This was tested and makes a big difference in tenderness.
- Use two heat zones on the Blackstone so the vegetables stay crisp and don’t get mushy.
- Don’t overcrowd the griddle—cook in batches if needed for better browning.
- Keep the cook time short to avoid overcooking the steak.
Variations & Substitutions
- Beef swap: Use sirloin or shaved beef if it’s on sale.
- Lower sodium: Use low-sodium soy sauce. You can also use coconut aminos for a gluten free variation.
- Add veggies: Mushrooms or zucchini work well if you need to stretch the meal.
- No Blackstone: Cook in a large skillet or wok over high heat on the stovetop.
Storage & Freeze Instructions
- Refrigerator: Store leftovers in an airtight container for up to 4 days.
- Freezer: Freeze cooked pepper steak (without rice) for up to 2 months.
- Reheat: Warm in a skillet for best texture or microwave in short intervals. Add a splash of water if needed to loosen the sauce.
- Meal prep tip: Double the recipe and serve over fresh rice throughout the week.
