Ingredients

• 1.5 pounds sweet potatoes, peeled and cut into 1-inch cubes
• 2 tablespoons olive oil
• 1 teaspoon smoked paprika
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/2 teaspoon ground black pepper
• 1 teaspoon kosher salt, divided (plus more to taste)
• 1.25 to 1.5 pounds sirloin, strip steak, or ribeye, cut into 1-inch cubes
• 1 tablespoon cornstarch (optional, for extra crust on steak)
• 1.5 tablespoons high-heat oil (avocado, canola, or grapeseed)
• 3 tablespoons unsalted butter
• 3 cloves garlic, minced
• 1 tablespoon fresh rosemary or thyme, chopped (or 1 teaspoon dried)
• 1 tablespoon fresh lemon juice
• Red pepper flakes, to taste (optional)
• Fresh parsley, chopped, for garnish

Step-by-Step Instructions

1. Preheat and prep the pan: Heat the oven to 425°F (220°C).

   Line a sheet pan with parchment for easier cleanup. This high heat helps the sweet potatoes crisp.

2. Season the sweet potatoes: Toss the cubes with olive oil, smoked paprika, garlic powder, onion powder, 1/2 teaspoon salt, and black pepper. Spread in a single layer so they roast, not steam.
3. Roast until crisp-tender: Bake for 20 minutes, then flip.

   Continue roasting 10–15 more minutes, until the edges are browned and the centers are tender. Keep warm.

4. Pat the steak dry: While the potatoes roast, blot the steak cubes with paper towels. Dry meat sears better and gets that nice crust.
5. Season the steak: Sprinkle with the remaining 1/2 teaspoon salt and a pinch more pepper.

   If you want extra sear, toss the cubes with the cornstarch to create a light coating.

6. Preheat the skillet: Heat a large cast-iron or heavy stainless skillet over medium-high until very hot. Add the high-heat oil.
7. Sear in batches: Add half the steak cubes in a single layer. Don’t crowd the pan.

   Sear 1–2 minutes per side until browned outside and medium-rare inside. Transfer to a plate and repeat with the second batch.

8. Make the garlic-herb butter: Lower heat to medium. Add the butter to the skillet.

   When melted and foamy, stir in the garlic and herbs. Cook 30–45 seconds, just until fragrant—don’t brown the garlic.

9. Coat the steak: Return all steak bites (and any juices) to the skillet. Toss in the garlic butter for 30–60 seconds.

   Squeeze in the lemon juice and add red pepper flakes if using. Taste and adjust salt.

10. Plate and garnish: Serve the steak bites over or alongside the roasted sweet potatoes. Spoon any extra butter from the skillet over the top.

    Sprinkle with fresh parsley.

Storage Instructions

• Refrigerate: Store leftovers in an airtight container for up to 3 days. Keep the steak and sweet potatoes together or separate—your call.
• Reheat: Warm in a hot skillet over medium heat with a dab of butter or a splash of water, 2–4 minutes, just until heated through. Avoid microwaving too long or the steak can turn tough.
• Freeze: You can freeze for up to 2 months, though texture is best fresh.

  Thaw overnight in the fridge and reheat gently.

Why This is Good for You

This meal offers a strong balance of nutrients. Steak provides protein, iron, zinc, and B vitamins, which support muscle recovery and energy. Sweet potatoes bring complex carbs, fiber, and beta-carotene, a powerful antioxidant that supports eye and immune health. Cooking with herbs and garlic adds flavor without relying on heavy sauces. You get a satisfying, steady energy meal that feels indulgent but still checks a lot of boxes.

Pitfalls to Watch Out For

• Overcrowding the pan: Too many steak cubes at once will steam instead of sear.

  Work in batches for a proper crust.

• Wet steak: Moisture blocks browning. Pat the meat dry before seasoning and searing.
• Overcooking the garlic: Garlic turns bitter if it browns. Keep the heat moderate when making the butter sauce.
• Undercooked sweet potatoes: If your cubes are larger than 1 inch, they’ll need more time.

  Roast until they’re tender when pierced with a fork.

• Skipping rest time: If the steak seems tight, let it sit off heat for a minute after searing so the juices redistribute.

Alternatives

• Protein swaps: Try chicken thighs (cut into 1-inch pieces) or pork tenderloin cubes. Adjust cook time and ensure safe internal temperatures.
• Different steak cuts: Sirloin is a great value. Strip steak and ribeye are richer and more tender.

  Flank or skirt works, but slice against the grain and cook quickly.

• Seasoning twists: Use Cajun seasoning, chili-lime, or a coffee-rub blend. For a sweeter note, add a drizzle of maple to the butter.
• Veggie additions: Roast Brussels sprouts, red onions, or bell peppers on the same sheet pan as the sweet potatoes. Add a handful of baby spinach to the skillet at the end to wilt in the butter.
• Dairy-free: Swap butter for olive oil or vegan butter.

  Add a splash of balsamic for richness.

• Low-carb: Replace sweet potatoes with cauliflower or zucchini. Roast at a slightly lower temp (400°F) to prevent over-browning.

FAQ

What’s the best steak cut for steak bites?

Sirloin is reliable and affordable. Strip steak and ribeye are more tender and marbled, which gives you extra flavor and a buttery feel.

Choose a cut with decent marbling for the best sear and juiciness.

How do I know when the steak bites are done?

For medium-rare, the centers should feel springy and warm, and an instant-read thermometer should read around 130–135°F. They cook fast—usually 2–3 minutes total per side, depending on size. Pull them slightly early since they keep cooking in the pan with the butter.

Can I make this in the air fryer?

Yes.

Roast the sweet potatoes at 390°F for about 15–20 minutes, shaking halfway. For the steak, air-fry in a single layer at 400°F for 5–7 minutes, checking at 5. Toss both with garlic-herb butter in a skillet or bowl afterward.

Do I need cornstarch on the steak?

No, it’s optional.

Cornstarch helps create a thin crust and can prevent sticking in stainless pans. If your pan runs hot and you pat the steak dry, you’ll still get great sear without it.

How can I meal prep this?

Roast the sweet potatoes and cook the steak bites ahead, keeping the garlic-herb butter separate. Reheat steak gently in a skillet with the butter so it stays tender.

Pack with a green veggie or a quick salad for balanced lunches.

What’s a good sauce to serve on the side?

Garlic aioli, chimichurri, or a simple yogurt-herb sauce pairs well. A squeeze of extra lemon and a drizzle of hot honey also brighten the plate without much effort.

Can I make it spicy?

Absolutely. Add red pepper flakes to the butter, or use a spicy seasoning blend on the sweet potatoes.

A little chipotle powder also brings smoky heat.
