Why You’ll Love These Whole30 Steak Bites
- Fast but hearty: You get protein + veggies + carbs in one pan (hello, balanced plate).
- Flavor-packed: Coconut aminos + garlic + cracked pepper = savory goodness without fuss.
- Picky-eater friendly: Everything is in bite-size pieces. Somehow that makes it “more fun.” (Kids are mysterious.)
Ingredients You’ll Need
Here’s what we’re working with (nothing weird, nothing hard to find):
- 1 large sweet potato (about 12 ounces), diced into 1″ pieces
- 1 teaspoon sea or kosher salt
- 1 lb flat iron steak, diced into 1″ pieces
- 3 tablespoons olive oil, divided
- 2 cloves garlic, minced
- 2 bell peppers, seeded and diced into 1″ pieces
- 4 green onions, thinly sliced
- 2 tablespoons coconut aminos
- 2 teaspoons cracked black pepper
- 2 tablespoons fresh chopped cilantro
How to Make Steak Bites with Sweet Potatoes and Peppers
Step 1: Pre-soften the sweet potatoes (the weeknight shortcut)
You want them barely tender—a knife should slide in but still meet a little resistance. If they’re fully soft now, they’ll turn mushy later… and nobody wants sad, squishy potatoes pretending to be dinner.
Step 2: Sear the steak bites
Heat a 12-inch skillet over high heat. Add 2 tablespoons olive oil and heat until shimmering.
Remove the steak with a slotted spoon and set it on a plate. (Try not to snack on too many “tester bites.” I never said I was perfect.)
Step 3: Brown the sweet potatoes in the skillet
Add the remaining 1 tablespoon olive oil to the same skillet.
Step 4: Add garlic (without burning it)
Make a small well in the center of the pan and add the minced garlic. Sauté about 1 minute, stirring occasionally, just until fragrant.
If garlic could talk, it would say: “Please don’t burn me.” So we listen.
Step 5: Add peppers + green onions
Step 6: Bring it all together with coconut aminos
Add the steak (plus any juices on the plate) back into the skillet. Pour in the coconut aminos and toss everything.
Cook another 1–2 minutes, until the liquid evaporates and coats everything like a savory glaze.
Step 7: Finish with pepper + cilantro
Serve immediately, and sprinkle with extra cilantro if you love that fresh pop. (If you’re not a cilantro person, I forgive you. We can still be friends.)
Aneta’s Cozy Kitchen Tips
- Cut everything the same size. 1-inch pieces cook evenly and keep dinner from turning into a “some bites are perfect, some bites are… chewy” experience.
- Microwave step is your best friend. It saves time and keeps the sweet potatoes from taking forever in the pan.
- If your pan looks dry, add a tiny splash of oil. Whole30 cooking isn’t about suffering—your food should taste good.
