Steak Bites with Sweet Potatoes & Peppers

Introduction

There’s something deeply satisfying about a skillet dinner that feels both hearty and fresh—and this dish delivers exactly that. With juicy cubes of steak seared to perfection, sweet potato chunks offering a touch of natural sweetness and chew, and vibrant bell peppers adding crisp color and brightness, this meal brings comfort with a sophisticated twist. The aroma of sizzling steak followed by garlic and the gentle hiss of sweet potatoes in olive oil sets the mood: everyone gathering around the table, the kitchen warm and welcoming.

At the heart of the dish is the meat—rich, savory and seared right—but it’s paired with real food sides that make each bite balanced and complete. The flavors mingle: the caramel‑notes from the sweet potato, the smoky crust on the steak, the fresh burst of cilantro at the end. It’s the kind of dinner you’ll want for a regular weeknight, but it feels special enough for company. And because it’s designed with the Whole30 approach in mind—grain‑free, dairy‑free, full of veggies—you’ll walk away satisfied and energized, not heavy and sluggish.

Let’s dive into how to build this skillet of flavor and keep things simple, vibrant, and utterly delicious.

Ingredients

• 1 large sweet potato (≈12 oz), diced into 1‑inch pieces
• 1 teaspoon sea salt or kosher salt (for sweet potatoes)
• 1 lb (≈450 g) flat iron steak, trimmed and diced into 1‑inch cubes
• 3 tablespoons olive oil, divided (2 Tbsp + 1 Tbsp)
• 2 cloves garlic, minced
• 2 bell peppers, seeded and diced into 1‑inch pieces
• 4 green onions, thinly sliced
• 2 tablespoons coconut aminos (or soy/tamari if not Whole30)
• 2 teaspoons cracked black pepper
• 2 tablespoons fresh chopped cilantro, for garnish

Yield: about 4 servings.

Instructions

1. Place the diced sweet potato into a microwave‑safe bowl. Sprinkle with the salt, cover with a plate and microwave on high for 4–6 minutes, stirring once halfway. The sweet potatoes should be just tender—dense enough to hold shape but no longer raw.
2. Pat the diced steak dry with paper towels, then season lightly with salt/pepper. Heat a large 12‑inch skillet over high heat. Add 2 Tbsp olive oil, let it shimmer. Add the steak in a single layer and sear for about 10 minutes, turning every ~2 minutes, until browned outside and medium inside. Remove steak with a slotted spoon and set aside.
3. In the same skillet, add the remaining 1 Tbsp olive oil. Add the sweet potato pieces and toss to coat. Cook for about 3–4 minutes, stirring occasionally, until they gain some color.
4. Create a well in the center of the pan, add the minced garlic, sauté for about 1 minute until fragrant. Then add the diced bell peppers and the green onions. Toss with the sweet potatoes and cook 3–4 minutes more until the peppers are just tender.
5. Return the seared steak (along with any juices) back into the skillet. Pour in the 2 tablespoons of coconut aminos and sprinkle the cracked black pepper. Toss everything together and cook for an additional 1–2 minutes, until the liquid evaporates and everything is well combined.
6. Remove from heat, stir in the chopped cilantro, and serve immediately.

You Must Know (Helpful Tips)

• Make sure to pat the steak dry before searing to get a good crust instead of steaming.
• Don’t overcook the sweet potatoes in the microwave—they should still hold shape, or they’ll become mushy in the pan.
• Use a very hot skillet for the steak so you get browning. If the pan is too cool, you’ll end up with gray steak instead of caramelized.
• After adding the coconut aminos (or substitute), cook just until the liquid evaporates so you keep the flavor without making the dish too wet.
• Garnish with the cilantro at the end for freshness—don’t cook it too much or the flavor fades.

Storage Tips

• Refrigerator: Store leftovers in an airtight container for up to 3 days. Re‑heat gently in a skillet over medium heat to maintain quality.
• Freezer: This dish is best fresh, but you could freeze the steak‑sweet potato mixture (without garnish) for up to 1 month. Thaw overnight in fridge, then re‑warm in skillet.
• When reheating, you may add a splash of water or broth to revive the veggies if they seem dry.

Ingredient Substitutions

• Steak cut: Flat iron is recommended, but you could use sirloin or skirt steak. Just make sure to dice into 1‑inch pieces.
• Coconut aminos: If you’re not following Whole30, regular soy sauce or tamari works but changes the flavor slightly.
• Sweet potatoes: If you prefer regular potatoes, you can substitute—but cook time and texture will differ.
• Bell peppers: Any color (red, yellow, orange) will work; for milder flavor use yellow.
• Cilantro: If you don’t like cilantro, you could substitute chopped parsley or green onion tops.

Serving Suggestions

• Serve with a side of steamed green beans or roasted broccoli for extra veggies.
• For extra crunch, sprinkle with lightly toasted pumpkin seeds.
• A wedge of lime on the side enhances the flavors if you enjoy a zesty finish.
• Because it’s a full plate (protein + veggie + starch), you can serve it as is—or alongside a simple salad for freshness.

Pro Tips

• Pre‑cut your vegetables the night before for faster weeknight execution.
• If you have a cast iron skillet, use it—that extra heat retention helps get that beautiful sear on the steak.
• If your microwave is very strong, reduce the sweet potato time to 3–4 minutes, otherwise they may become too soft.
• When adding garlic, keep it in the center of the pan (well technique) so it cooks gently and doesn’t burn on the pan edge.
• Let the dish sit for a minute off the heat before serving so juices settle and flavors come together.

Frequently Asked Questions (FAQ)

Q: Can I use a different potato instead of sweet potato?
A: Yes, you can use regular white potatoes or Yukon golds, but you’ll likely need to adjust cooking time and expect a slightly different taste and texture. Sweet potatoes bring natural sweetness and a firmer bite that pairs well.

Q: Is this recipe strictly for Whole30?
A: The original recipe is designed to be Whole30‑compliant (grain‑free, dairy‑free, gluten‑free) but it’s absolutely suitable for anyone seeking a flavorful, balanced meal—even if you’re not on the program.

Q: How many servings does it make?
A: The recipe yields about 4 servings.

Q: My steak turned out tough—what happened?
A: Possible causes: the pieces were too large, steak was cooked too long, or the skillet heat was too low resulting in steaming rather than searing. Aim for medium doneness and high heat sear.

Q: Can I skip the microwave step for the sweet potatoes?
A: Yes—you could roast them in the oven or parboil on the stove until just tender, then finish them in the skillet. Just ensure they’re not overcooked at the start.
