👨🍳 Instructions
Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Toss the sweet potato wedges in one tablespoon of olive oil, garlic powder, smoked paprika, salt, and pepper directly on the baking sheet.
Roast the sweet potato wedges for 15 minutes while you prepare and season the lean beef steak with remaining salt, pepper, and herbs.
Push the sweet potatoes to one side of the sheet pan and place the seasoned steak on the open side.
Return the sheet pan to the oven and roast for an additional 10 to 12 minutes until the steak reaches medium-rare doneness and potatoes are tender and crisp.
Remove from the oven, let the steak rest for 5 minutes before slicing thinly against the grain, and serve warm with the sweet potato wedges.
⚠️ Common Mistakes
- ✕
Cutting steak with the grain: Always slice flank or sirloin steak across the grain to ensure tender, easy-to- chew bites.
- ✕
Overcrowding the pan: Give sweet potato wedges space on the baking sheet so they roast and crisp instead of steaming.
🔄 Variations
Butternut squash swap: Substitute cubed butternut squash for the sweet potato wedges.
Herb butter finish: Add a small pat of garlic herb butter on top of the warm steak just before slicing.
Dairy-free safety: Naturally 100% dairy-free and nut-free for safe family dinners.
🧊 Storage
- 📦
Refrigerator leftovers: Store leftover sliced steak and sweet potato wedges in an airtight container in the refrigerator for up to 3 days.
- 📦
Reheating habits: Reheat gently in a skillet over medium heat or in the microwave until warmed through.
💡 Chef Tips
Resting meat trick: Letting the cooked steak rest for 5 minutes locks in flavorful juices so the meat stays tender.
Wedge uniform cutting: Cut sweet potatoes into equal thickness so they roast evenly alongside the fast-cooking steak.
Sheet pan efficiency: Using a single sheet pan minimizes cleanup while delivering a complete high-protein family meal.
