How to Make Whole30 Steak Bites with Sweet Potatoes and Peppers
Step 1: Prepare the Sweet Potatoes
Start by placing the diced sweet potatoes into a microwave-safe bowl. Sprinkle them with sea salt and cover. Microwaving them until they’re just barely tender helps them cook perfectly later without going mushy. This step saves time while ensuring they still hold their shape when sautéed.
Step 2: Sear the Steak
Heat a large skillet over high heat and add two tablespoons of olive oil. Once shimmering, add the diced steak in a single layer. Cooking it evenly ensures those delicious browned bits form while keeping the center juicy. After about ten minutes, remove it from the skillet so it doesn’t overcook.
Step 3: Cook the Sweet Potatoes
In the same skillet, add another tablespoon of olive oil and toss in those sweet potatoes. Stir occasionally until they’re golden brown — this adds wonderful texture and brings out their natural sweetness, which pairs beautifully with the savory steak.
Step 4: Add Garlic
Make a little well in the center of your pan and toss in minced garlic. Sautéing it briefly releases its fragrant aroma — you’ll know it’s ready when you can smell that delicious garlicky goodness!
Step 5: Toss in Bell Peppers and Scallions
Now it’s time to add your colorful bell peppers and green onions! Toss everything together gently as they sauté until tender-crisp. This helps maintain their vibrant color while infusing your dish with even more flavor.
Step 6: Combine Everything Together
Return your perfectly cooked steak to the skillet along with any juices left behind. Drizzle in coconut aminos for that touch of umami goodness! Toss everything together until heated through; this step brings all those fantastic flavors into one hearty dish.
Step 7: Serve It Up!
Finally, stir in fresh cilantro right before serving. Portion onto plates and feel free to garnish with additional cilantro if desired! These Whole30 Steak Bites with Sweet Potatoes and Peppers are best enjoyed immediately while everything is hot and fresh!
Pro Tips for Making Whole30 Steak Bites with Sweet Potatoes and Peppers
Cooking can be a delightful experience, and these tips will help you elevate your dish!
Use a quality steak: Choosing a high-quality flat iron steak ensures that your bites are tender and flavorful. Look for cuts with good marbling for the best results.
Don’t overcrowd the pan: Cooking the steak in a single layer allows for even browning and prevents steaming. If needed, cook in batches to achieve that perfect sear.
Prepping ahead: Dice your sweet potatoes and peppers in advance to save time during meal prep. Having everything ready to go makes the cooking process smoother and more enjoyable.
Adjust seasoning to taste: Feel free to tweak the amount of salt or pepper based on your preferences. This recipe is versatile, so make it your own!
Let it rest: After cooking, allow the steak to rest for a few minutes before serving. This helps retain its juices, resulting in a more delicious bite.
