Sweet Potato and Steak Bites with Peppers Recipe
Introduction
This vibrant dish features tender bites of flat iron steak paired with sweet potatoes and colorful bell peppers. It’s a quick, flavorful meal perfect for a weeknight dinner that balances savory, sweet, and fresh elements beautifully.

Ingredients
- 1 large sweet potato (about 12 ounces), diced into 1″ pieces
- 1 tsp sea or kosher salt
- 1 lb flat iron steak, diced into 1″ pieces
- 3 tbsp olive oil, divided
- 2 cloves garlic, minced
- 2 bell peppers, seeded and diced into 1″ pieces
- 4 green onions, thinly sliced
- 2 tbsp coconut aminos
- 2 tsp cracked black pepper
- 2 tbsp fresh chopped cilantro
Instructions
- Step 1: Place the diced sweet potatoes into a microwave-safe bowl and sprinkle with 1 teaspoon of salt. Cover with a plate and microwave on high for 4-6 minutes, stirring once halfway through. The sweet potatoes should be just barely tender—pierce one with a knife and expect slight resistance. Avoid overcooking to prevent mushiness.
- Step 2: Heat a 12-inch skillet over high heat. Add 2 tablespoons of olive oil and heat until shimmering. Add the steak pieces in a single layer. Cook, turning every two minutes, until the steak is browned and cooked to medium doneness, about 10 minutes. Remove the steak with a slotted spoon and set aside on a plate.
- Step 3: Add the remaining tablespoon of olive oil to the skillet. Add the sweet potatoes and toss to coat in the oil. Cook, stirring occasionally, until browned, about 3-4 minutes.
- Step 4: Create a well in the center of the pan and add the minced garlic. Sauté, stirring occasionally, until fragrant, about 1 minute.
- Step 5: Add the diced bell peppers and sliced green onions to the skillet. Toss with the sweet potatoes and sauté until the peppers are just tender, about 3-4 minutes.
- Step 6: Return the steak and its juices to the skillet along with the coconut aminos. Toss all ingredients together and cook for another 1-2 minutes until the liquid evaporates.
- Step 7: Sprinkle with cracked black pepper and chopped cilantro, toss to combine, and remove from heat. Serve immediately, garnished with extra fresh cilantro if you like.
Tips & Variations
- For added spice, sprinkle in a pinch of red pepper flakes along with the black pepper.
- Swap flat iron steak for sirloin or skirt steak if preferred.
- Use tamari instead of coconut aminos for a gluten-free soy sauce alternative.
- To make it vegetarian, substitute steak with firm tofu or tempeh and increase the cooking time for browning accordingly.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over medium heat to maintain texture, adding a splash of water or oil if needed to prevent sticking.

FAQs
Can I prepare this recipe without a microwave?
Yes, you can par-cook the sweet potatoes by steaming or boiling them until just tender, about 8-10 minutes, then proceed with the recipe to avoid mushiness.
What can I use if I don’t have coconut aminos?
Coconut aminos can be replaced with tamari or low-sodium soy sauce for a similar savory flavor. Adjust the amount to taste, as these alternatives can be saltier.

Ingredients
Vegetables
- 1 large sweet potato (about 12 ounces), diced into 1″ pieces
- 2 bell peppers, seeded and diced into 1” pieces
- 4 green onions, thinly sliced
- 2 cloves garlic, minced
- 2 tbsp fresh chopped cilantro
Meat
- 1 lb flat iron steak, diced into 1” pieces
Oils & Sauces
- 3 tbsp olive oil (divided)
- 2 tbsp coconut aminos
Seasonings
- 1 tsp sea or kosher salt
- 2 tsp cracked black pepper
Instructions
- Pre-cook the Sweet Potatoes: Place diced sweet potatoes in a microwave-safe bowl and sprinkle with 1 teaspoon salt. Cover with a plate and microwave on high for 4-6 minutes until just barely tender, stirring once halfway through. The potatoes should be soft enough to pierce with a knife tip but still hold shape to avoid mushiness later.
- Cook the Steak: Heat a 12-inch skillet over high heat and add 2 tablespoons olive oil until shimmering. Spread the steak pieces in a single layer and cook, turning every two minutes, until browned on all sides and medium in the center, about 10 minutes. Use a slotted spoon to remove the steak and set aside on a plate.
- Brown the Sweet Potatoes: Add the remaining tablespoon of olive oil to the skillet. Toss in the par-cooked sweet potatoes and cook, stirring occasionally, until they develop a browned crust, roughly 3-4 minutes.
- Sauté Garlic: Create a well in the center of the skillet and add minced garlic. Sauté with occasional stirring until fragrant, about 1 minute.
- Add Peppers and Green Onions: Add diced bell peppers and sliced green onions to the skillet, tossing them with the sweet potatoes. Sauté together until the peppers become bite-tender, approximately 3-4 minutes.
- Combine Steak and Seasoning: Return the cooked steak and its juices to the pan along with 2 tablespoons of coconut aminos. Toss all ingredients well and cook for another 1-2 minutes until the liquid reduces and evaporates.
- Finish and Serve: Season with cracked black pepper and stir in fresh chopped cilantro. Remove from heat, portion onto plates, garnish with extra cilantro if desired, and serve immediately.
Notes
- Be careful not to overcook the sweet potatoes in the microwave to prevent mushy texture.
- Flat iron steak can be substituted with other tender cuts like sirloin or ribeye.
- Coconut aminos add a mild soy-like flavor; substitute with tamari or low-sodium soy sauce if preferred.
- Adjust the amount of black pepper to taste.
- This dish is best served fresh from the skillet for optimal texture and flavor.
