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 salt, cover with a plate, and microwave on high until they’re just barely tender—about 4 to 6 minutes. This step ensures that your sweet potatoes cook evenly later in the skillet without turning mushy.
Step 2: Sear the Steak
Next, heat a large skillet over high heat. Add 2 tablespoons of olive oil and let it get shimmering hot. Then add the diced steak in a single layer. Cooking them evenly allows for that perfect browning while keeping them juicy inside. After about 10 minutes of turning every two minutes, remove them from the skillet using a slotted spoon.
Step 3: Cook the Sweet Potatoes
In the same skillet, add another tablespoon of olive oil. Toss in those prepped sweet potatoes and let them brown up nicely—about 3 to 4 minutes will do! Stir occasionally so they don’t stick but allow them time to develop that lovely golden color.
Step 4: Sauté Garlic
Once your sweet potatoes are browned, make a well in the center of the pan. Add minced garlic and sauté until fragrant—around one minute. This step is crucial as it infuses all those delicious flavors into your dish!
Step 5: Add Peppers and Scallions
Now it’s time to add diced bell peppers and sliced green onions into the mix. Toss everything together and sauté until those peppers are just tender—about another 3 to 4 minutes. This will give you that vibrant crunch that perfectly complements the steak bites.
Step 6: Combine Everything
Return your cooked steak along with any juices back to the skillet. Pour in coconut aminos for an added depth of flavor. Toss everything together gently but thoroughly so all those wonderful tastes meld together beautifully.
Step 7: Finish Off
Finally, toss in cracked black pepper and fresh cilantro right before serving. Give everything one last stir before plating up this delightful dish! Top with extra cilantro if desired, then enjoy immediately while it’s warm!
Pro Tips for Making Whole30 Steak Bites with Sweet Potatoes and Peppers
To make your cooking experience smoother and the end result even better, consider these helpful tips!
-
Prep Ahead: Chop the sweet potatoes and bell peppers in advance to save time during the cooking process. Having everything ready will help you maintain momentum and minimize stress.
-
Don’t Overcrowd the Pan: When cooking the steak, ensure it’s spread out in a single layer. This allows for even browning and prevents steaming, resulting in deliciously caramelized bites.
-
Adjust Seasoning to Taste: Feel free to modify the amount of sea salt and cracked black pepper based on your personal preference. Tasting as you go helps develop flavors that cater to your palate.
-
Use Fresh Herbs: Adding fresh cilantro at the end brightens up the dish significantly. Fresh herbs not only enhance flavor but also add a pop of color to your plate.
-
Experiment with Cooking Time: If you prefer your steak cooked differently (rare or well-done), adjust the cooking time accordingly. Just keep an eye on it to avoid overcooking!
