For the Sauce:
- ¾ cup low-sodium beef broth
- ⅓ cup soy sauce (or tamari for GF)
- ¼ cup oyster sauce
- 2 tbsp hoisin sauce
- 2 tbsp brown sugar (or honey)
- 1 tbsp rice vinegar
- 1 tbsp fresh ginger, minced
- 3 cloves garlic, minced
- 1 tsp cornstarch + 2 tbsp water (slurry, for thickening)
🥩 Steak tip: Partially freeze the steak for 30 minutes—it slices paper-thin with ease!
Step-by-Step Instructions
1. Sear the Steak (Optional but Recommended)
Heat 1 tbsp sesame oil in a skillet over high heat. Working in batches, sear steak 1–2 minutes per side until browned (not cooked through). Transfer to slow cooker.
💡 Why sear? It locks in juices and adds depth—skip only if you’re in a rush.
2. Sauté the Aromatics (Also Optional but Worth It)
In the same skillet, add remaining 1 tbsp oil. Sauté onions and peppers for 3–4 minutes until slightly softened. Add garlic and ginger; cook 30 seconds. Transfer to slow cooker.
3. Build the Sauce
In a bowl, whisk beef broth, soy sauce, oyster sauce, hoisin, brown sugar, and rice vinegar. Pour over steak and veggies.
4. Slow Cook to Tenderness
Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours, until beef is fork-tender.
5. Thicken the Sauce
In the last 30 minutes, stir in cornstarch slurry. Cover and cook until sauce thickens to a glossy glaze.
Tips for Pepper Steak Perfection
- Slice steak against the grain—this ensures tenderness.
- Don’t skip the cornstarch—it gives that signature glossy, clingy sauce.
- Use low-sodium soy sauce—prevents the dish from becoming too salty.
- Make it ahead: Cook, cool, and refrigerate for up to 3 days. Reheat gently on the stove.
- Freezer-friendly: Freeze cooked pepper steak (without rice) for up to 3 months.
Serving Suggestions That Shine
- Classic: Over steamed white or brown rice
- Low-Carb: Serve with cauliflower rice or zucchini noodles
- Extra veggies: Stir in broccoli or snap peas in the last 30 minutes
- Garnish: Top with sesame seeds and sliced green onions
Delicious Variations
- Spicy Pepper Steak: Add 1 tsp chili garlic sauce or red pepper flakes
- Pineapple Twist: Stir in ½ cup pineapple chunks for sweetness
- Mushroom Medley: Add 8 oz sliced mushrooms with the peppers
- Gluten-Free: Use tamari, GF oyster sauce (like Kikkoman), and certified GF hoisin
Frequently Asked Questions (FAQs)
Q: Can I skip searing the beef?
A: Yes—but the flavor will be less complex. For best results, at least sauté the aromatics.
Q: Why is my sauce too thin?
A: Likely not enough cornstarch or not cooked long enough after adding slurry. Simmer uncovered for 10 minutes to reduce.
Q: Can I use frozen peppers/onions?
A: Not recommended—they release too much water and turn mushy.
Q: Can I add the sauce ingredients directly to the slow cooker?
A: Yes—but mix them first to ensure even flavor distribution.
