Since then, this sheet-pan supper has become my Friday-night love letter to the weekend, my “I’ve-got-company-coming-but-I-want-to-enjoy-them-not-the-stove” secret, and the meal my teenage son requests the minute he smells the rosemary hitting hot olive oil. It scales up for a crowd, scales down for a date night, and—because everything cooks together—leaves me free to shake up a negroni or simply sit on the porch while the oven does the heavy lifting. If you can chop a potato and season a steak, you can master this dish. Let me show you how.
Why This Recipe Works
- One pan, zero fuss: Steak, potatoes, and veg roast together, creating built-in jus and minimizing dishes.
- Reverse-sear trick: Low-and-slow start keeps the steak edge-to-edge rosy, while a final broil builds crave-worthy crust.
- Starchy sponge: Par-cooking potatoes on the same pan lets them soak up rendered beef fat for outrageous flavor.
- Herb-infused oil: Warm olive oil gently blooms garlic and rosemary so every bite tastes like a steakhouse butter baste—without the butter.
- Customizable cuts: Works with rib-eye, strip, sirloin, or even flank—timing chart included.
- Meal-prep hero: Leftovers reheat like a dream and the potatoes become tomorrow’s hash.
Ingredients You'll Need
Steak – 1½ to 2 lb (680–900 g) of 1–1¼-inch thick rib-eye or strip, trimmed of large pieces of surface fat but leaving the white ribbon in the center (flavor insurance). Look for abundant marbling—those little flecks of fat that melt into juice. If you prefer sirloin, choose top sirloin center-cut; it’s leaner so we’ll compensate with a quicker sear. Frozen steak? Thaw 24 h on a rimmed plate in the fridge, then unwrap and air-dry in the fridge overnight for best crust.
Baby (or fingerling) potatoes – 1½ lb (680 g), golf-ball size or smaller so they roast in the same time as the steak. If yours are larger, halve them; the cut side becomes a crunchy golden lid that absorbs juices. Substitute Yukon Gold or red bliss, but avoid russets—they’ll fall apart before the steak finishes.
Extra-virgin olive oil – 3 Tbsp. A fruity, peppery oil stands up to beef; save the grassy finishing oil for the final drizzle. Avocado oil works for high-heat purists, but you’ll miss the flavor.
Garlic – 4 large cloves, smashed and peeled. We’re flavoring the oil, not burning the garlic, so leave them chunky.
Fresh rosemary – 3 sprigs plus 1 tsp chopped. The sprigs perfume the oil; the chopped bits turn into crispy herb chips on the potatoes. No fresh? Sub 1 tsp dried rosemary for the oil only, then add 1 tsp fresh thyme leaves to the potatoes for green flecks.
Kosher salt & freshly ground black pepper. Diamond Crystal dissolves fastest; if you use Morton, scale back by 20 %. A 50-50 mix of black and pink peppercorns adds subtle floral heat.
Optional veg: 1 cup cherry tomatoes or 1 cup trimmed green beans added during the last 10 minutes for color and built-in side dish.
How to Make Sheet Pan Steak and Potatoes for a Juicy Dinner
Preheat & set up for reverse-sear
Place a large rimmed sheet pan (13×18-inch) on the middle rack and heat oven to 275 °F (135 °C). Starting with a hot pan jump-starts caramelization and prevents the steak from steaming in its own juices. While the oven heats, pat the steak absolutely dry with paper towels—moisture is the enemy of crust. Season both sides with 1 tsp kosher salt per pound and a generous shower of cracked pepper, pressing so it adheres.
Infuse the oil
In a small skillet combine olive oil, smashed garlic, and rosemary sprigs. Warm over medium-low until the garlic barely bubbles and the rosemary crisps, 3–4 minutes. Remove from heat; let steep while you prep potatoes. This scented oil is the stealth flavor bomb that seasons every bite.
Cut & par-cook potatoes
Halve any potatoes larger than a walnut so all pieces are uniform. Transfer to a microwave-safe bowl, add 2 Tbsp water, cover, and microwave on HIGH 4 minutes. This partial cook guarantees creamy centers without waiting for the steak to finish. Drain well; return to the warm bowl and toss with 2 Tbsp of the infused oil, ½ tsp salt, chopped rosemary, and a few grinds of pepper.
Arrange on the hot pan
Carefully remove the preheated sheet pan (it’s 275 °F, not blazing, but still use mitts). Brush with 1 tsp of the infused oil. Scatter potatoes cut-side down; nestle the steak in the center, surrounded by potatoes like a beefy island. The direct contact with hot metal starts crust formation on both steak and spuds.
Low-and-slow roast
Return pan to the middle rack and roast 20 minutes for 1-inch steak or 25 minutes for 1¼-inch. Target internal temp is 90 °F (32 °C) for rare, 100 °F (38 °C) for medium-rare—this is just the first phase. Meanwhile, line a small plate with the reserved rosemary sprigs and garlic; you’ll use them again.
Crank the heat for the sear
Remove pan; switch oven to BROIL on HIGH with rack 6 inches from element. Brush steak with remaining infused oil, top with the saved rosemary and garlic, and broil 2–4 minutes per side depending on thickness. For 1-inch steak, broil 2 min first side, flip, 2 min second side; for 1¼-inch, 3 min each side. You’re looking for 120 °F (49 °C) for rare, 130 °F (54 °C) for medium-rare. Potatoes should be mahogany on the bottoms and the rosemary leaves crackling.
Rest & finish
Transfer steak to a cutting board and tent loosely with foil; rest 10 minutes. Return potatoes to the oven (now off but still warm) while you pour yourself a victory beverage. Resting allows juices to redistribute so they don’t flood the board when you slice.
Slice & serve
Cut steak against the grain into ½-inch slices; return any juices to the pan and drag potatoes through them. Shower with flaky salt and an extra crack of pepper. Serve straight from the sheet pan for rustic charm, or plate over a bed of arugula so the greens wilt under the warm steak and take on the rosemary-scented oil.
Expert Tips
Use an instant-read thermometer
Steak thickness varies more than you think. Pull at 130 °F for perfect medium-rare after carry-over cooking.
Dry = crust
After salting, refrigerate steak uncovered on a rack for up to 24 h; the surface will feel tacky—ideal for browning.
Flip potatoes once
When you flip the steak under the broiler, flip potatoes too for even char without burning.
Make it midnight steak
Leftover cold steak sliced paper-thin on next-day salads or sandwiches rivals deli charcuterie.
Cast-iron upgrade
If you own a cast-iron griddle, place it upside-down under the broiler; the concentrated heat delivers steakhouse grill marks.
Color pop
Add a handful of multicolored cherry tomatoes during the last 5 minutes; they burst into sweet-tart pockets that sauce the plate.
Variations to Try
- Mexican street-corn twist: Replace rosemary with 1 tsp smoked paprika and 1 tsp ground cumin; finish with crumbled cotija, lime zest, and cilantro.
- Winter comfort: Swap potatoes for 1-inch cubes of butternut squash and add thick slices of red onion; finish with maple-mustard glaze under broiler.
- Low-carb option: Use cauliflower florets tossed in 1 Tbsp oil and 2 Tbsp grated Parmesan; roast 15 min total, adding steak halfway.
- Surf & turf: Nestle 6 peeled, deveined shrimp (tails on) around steak during the last 3 minutes of broiling; brush with garlic-butter.
- Vegan tablemates: Use thick slabs of cauliflower steak and chickpeas; season identically and roast 18 min at 400 °F, no reverse-sear needed.
Storage Tips
Refrigerate: Cool steak and potatoes within 2 hours. Store in separate airtight containers (prevents potatoes from absorbing meat odor). Steak keeps 4 days, potatoes 5 days.
Freeze: Slice steak and freeze flat on a parchment-lined sheet; transfer to a zip bag with air pressed out. Freeze potatoes on the same sheet, then bag. Both keep 3 months. Thaw overnight in fridge.
Reheat: Warm steak in a 250 °F oven until just 110 °F at center, 8–10 min, then sear 30 sec per side in a hot skillet for fresh crust. Potatoes reheat at 400 °F for 10 min; spritz with water first to re-crisp.
Make-ahead: Microwave potatoes up to 24 h ahead; refrigerate tossed in oil to prevent browning. Season steak up to 48 h ahead for deeper dry-brine flavor. When ready to cook, proceed from Step 4.
