Step‑by‑Step Instructions for Whole30 Steak Bites with Sweet Potatoes and Peppers
Step 1: Pre-cook Sweet Potatoes
Start by dicing your sweet potatoes into uniform cubes. In a microwave-safe bowl, add the sweet potatoes along with a pinch of sea salt. Cover the bowl and microwave on high for 4–6 minutes until just tender. The pieces should be fork-tender but not mushy, which ensures a delightful texture when combined with the steak bites.
Step 2: Sear the Steak
Heat 2 tablespoons of olive oil in a large skillet over high heat. Once the oil is shimmering, add the flat iron steak in a single layer, ensuring it doesn’t overcrowd the pan. Sear the steak for about 10 minutes, turning every 2 minutes until it’s nicely browned and reaches a medium doneness. Look for a golden crust and an internal temperature of 130–135°F for perfect steak bites.
Step 3: Cook Sweet Potatoes
After the steak is cooked, remove it from the skillet and set aside to rest. In the same skillet, add an additional tablespoon of olive oil if needed, and then toss in the pre-cooked sweet potatoes. Sauté them over medium-high heat for about 3–4 minutes until they acquire a nice char and start caramelizing, creating a flavorful base for your dish.
Step 4: Sauté Aromatics
Create a well in the center of the sweet potatoes and add minced garlic. Sauté for about 1 minute until fragrant, then stir in the sliced bell peppers and chopped green onions. Cook for an additional 3–4 minutes until the peppers soften and become vibrant, mingling their flavors with the sweet potatoes, enhancing the whole dish’s appeal.
Step 5: Combine Ingredients
Return the seared steak bites to the skillet, pouring in the coconut aminos. Gently toss everything together, allowing the liquid to coat the ingredients evenly. Cook for an extra 1–2 minutes until the dish is heated through and the coconut aminos reduce slightly. Watch for the mix to become fragrant and well-combined, highlighting the delicious medley of steak bites with sweet potatoes and peppers.
Step 6: Finish with Herbs
To bring freshness to your Whole30 steak bites, season with cracked black pepper to taste. Just before serving, sprinkle the dish with fresh chopped cilantro for a burst of color and flavor. This finishing touch will brighten up your meal, making it not only wholesome but visually appealing as well.

Steak Bites with Sweet Potatoes and Peppers Recipe FAQs
How do I select ripe sweet potatoes?
Look for sweet potatoes that are firm, smooth, and free from dark spots or blemishes. A good sweet potato should feel heavy for its size. If you see any soft spots or wrinkles, it’s best to avoid them, as these can indicate that the sweet potatoes are past their prime.
What is the best way to store leftover steak bites with sweet potatoes and peppers?
Store your leftovers in an airtight container in the refrigerator for up to 3 days. Make sure to let the dish cool completely before sealing it to prevent condensation. Reheat gently on the stovetop to maintain the original texture and flavor, stirring occasionally to avoid sticking.
Can I freeze steak bites with sweet potatoes and peppers?
Absolutely! To freeze, allow the dish to cool completely before transferring it to a freezer-safe bag. Make sure to squeeze out excess air before sealing. These can be stored in the freezer for up to 3 months. When ready to eat, thaw overnight in the refrigerator and reheat on the stovetop for best results.
What should I do if my steak is tough?
If the steak turns out tough, it may be due to overcooking or not using a tender cut. Always choose a high-quality cut like flat iron or sirloin and ensure you’re cooking it to medium doneness (130–135°F). For best results, let the steak rest for a few minutes after cooking; this helps redistribute the juices, making it more tender.
Are there any dietary considerations I should keep in mind for this recipe?
This recipe is gluten-free and suitable for Whole30 guidelines. However, if you have allergies or sensitivities, be mindful of the garlic and onion—consider alternatives like garlic powder or leaving them out entirely.
