Ingredients
- 2 lbs top sirloin steak, 1 inch thick
- 2 large sweet potatoes (about 2 lbs), cut into 1/2-inch cubes
- 1 lb fresh green beans, trimmed
- 3 tbsp olive oil, divided
- 1 tbsp smoked paprika
- 2 tsp garlic powder
- 1 tsp onion powder
- 1 tsp ground cumin
- 2 tsp kosher salt, divided
- 1 tsp black pepper
- 3 cloves garlic, minced
- 2 tbsp butter
- 1 tbsp fresh thyme leaves (or 1 tsp dried)
- Lemon wedges, for serving
Instructions
- 1
Preheat the oven to 425°F and line two sheet pans with parchment.
- 2
Toss the sweet potato cubes with 1 tablespoon olive oil, 1/2 teaspoon salt, and 1/2 teaspoon black pepper. Spread on one sheet pan and roast 25–30 minutes, flipping halfway, until caramelized at the edges and tender inside.
- 3
Toss the green beans with 1 tablespoon olive oil and 1/2 teaspoon salt. Spread on the second sheet pan and roast the final 12 minutes alongside the sweet potatoes until blistered and crisp-tender.
- 4
While the veggies roast, pat the steak completely dry — this is the #1 trick to a real crust. Combine smoked paprika, garlic powder, onion powder, cumin, the remaining 1 teaspoon salt, and 1/2 teaspoon pepper. Rub all over the steak.
- 5
Heat a large cast-iron skillet over high heat until smoking. Add the remaining 1 tablespoon olive oil. Sear the steak 3–4 minutes per side for medium-rare (130°F) or 4–5 minutes for medium (140°F).
- 6
In the last 60 seconds, add the butter, minced garlic, and thyme. Tilt the pan and spoon the foaming garlic-thyme butter over the steak.
- 7
Transfer steak to a cutting board and rest 8 minutes — non-negotiable for juicy slices. Slice thinly against the grain.
- 8
Divide steak, sweet potatoes, and green beans among 5 meal-prep containers. Tuck a lemon wedge into each (a squeeze right before eating wakes everything up).

Frequently Asked Questions
What cut of steak is best for meal prep?+
Top sirloin gives you the best ratio of flavor, tenderness, and price for meal prep. Flank, flat iron, and tri-tip also work great — all are lean enough to keep the macros tight and tender enough to reheat without turning to leather.
How do I keep meal prep steak from getting tough?+
Two rules: cook it no more than medium (140°F) since it'll heat further when reheated, and slice thinly against the grain. Reheat for 60 seconds max — long microwaves are what ruin steak.
How long does this meal prep last?+
4 days in the fridge in airtight containers. Steak actually tastes even better on day 2 once the flavors meld.
Can I use chicken or salmon instead?+
Absolutely — swap in seared chicken breast or roasted salmon. For salmon, check out our Salmon Rice Bowl as a swap-friendly base.
Are sweet potatoes good for high protein meal prep?+
Yes — they're packed with fiber, beta-carotene, and slow carbs that keep you full for hours. They reheat beautifully without going mushy, which is rare for a starch.
What sauce keeps the macros tight?+
A drizzle of chimichurri or a tablespoon of horseradish-Greek-yogurt sauce. Both add huge flavor for almost no calories.
