This platter is what happens when you stop deciding between steak night and potato night and just serve both from the same pan. A hot cast-iron skillet sears sliced sirloin until deeply browned, then the same fat crisps parboiled baby potatoes and blisters sweet peppers until their edges char and bubble.

The trick is sequencing: meat first for the crust, potatoes second for the crunch, and a fast garlic-butter finish that ties everything together. Everything lands on one platter in about 50 minutes, with a pan sauce made from the browned bits so nothing goes to waste.
Serve it family-style with crusty bread and a sharp mustard on the side, or plate it individually for a dinner-party look that took far less effort than it appears.
Why You'll Love This Recipe
About the Ingredients
1 3/4 lb (800g) sirloin steak, about 1 inch thick
Look for a steak with good marbling and even thickness so it sears uniformly. Flank steak or thick boneless pork chops work as a substitute, but reduce the sear time by about 2 minutes for flank.
1 1/2 lb (680g) baby Yukon Gold potatoes, halved
Small, uniform potatoes cook evenly; if yours are larger than a golf ball, quarter them. Red potatoes are a fine substitute and hold their shape just as well.
2 large red bell peppers, cut into 1-inch strips
Choose peppers that feel heavy for their size with glossy, tight skin. Yellow or orange bell peppers swap in easily and add a sweeter note.
1 large yellow onion, cut into 1/2-inch wedges
Keep the root end intact while cutting so the wedges hold together in the pan. Shallots or thick-sliced leeks can replace the onion.
3 tbsp (45ml) olive oil, divided
Use regular olive oil for the high-heat sear and save extra-virgin for finishing. Avocado oil is an excellent substitute with a higher smoke point.
4 tbsp (56g) unsalted butter
European-style butter browns more dramatically thanks to its higher fat content. Salted butter works, but then cut the added salt in the recipe by half.
4 cloves garlic, thinly sliced
Fresh garlic slices toast faster than minced, so they flavor the butter without burning. Jarred garlic is acceptable in a pinch but tastes flatter.
1 1/2 tsp kosher salt, plus more for the water
Diamond Crystal kosher salt is less dense than table salt; if using table salt, use about 1 teaspoon total. Sea salt flakes are a good finishing substitute.
1 tsp freshly ground black pepper
Coarse cracks release more aroma than pre-ground pepper. A smoked paprika pinch can be added alongside for a deeper crust.
2 tsp chopped fresh rosemary or thyme
Woody herbs stand up to the hot pan better than delicate ones. Dried herbs work at one-third the amount, added with the butter.
Tips & Tricks
- Dry the steak thoroughly with paper towels before searing; surface moisture steams instead of browning and costs you the crust.
- Parboil the potatoes until a knife slides in with slight resistance, about 8 minutes, then drain and let them steam-dry for 5 minutes so they crisp instead of sog.
- Don't crowd the skillet; if your pan is smaller than 12 inches, sear the meat in two batches so the temperature doesn't drop and the steak turns gray.
Pro Tips
Step-by-Step Instructions
1. Parboil the potatoes
Boil the halved potatoes in well-salted water at a rolling boil (212F/100C) for 8 to 10 minutes, until a paring knife pierces them with slight resistance. Drain and let them steam-dry in the colander for 5 minutes.
2. Season and preheat
Pat the steak bone-dry and season both sides with the kosher salt and black pepper. Heat a 12-inch cast-iron skillet over medium-high heat for 4 minutes until a drop of water sizzles and evaporates instantly.
3. Sear the steak
Add 1 tablespoon olive oil, then lay the steak in the pan away from you. Sear undisturbed for 4 minutes until a deep brown crust forms, flip, and cook 3 to 4 minutes more until an instant-read thermometer reads 130F (54C) for medium-rare. Transfer to a board and rest 5 minutes.
4. Crisp the potatoes
Add 1 tablespoon olive oil to the hot pan and add the potatoes cut-side down. Cook over medium-high heat for 6 to 7 minutes without stirring, until the cut sides are golden brown and release easily from the pan, then toss and cook 2 minutes more.
5. Blister the vegetables
Push the potatoes to the edge, add the remaining 1 tablespoon oil, then the peppers and onion. Cook for 5 to 6 minutes, stirring occasionally, until the pepper edges blister and the onion turns translucent and lightly charred.
6. Finish with garlic butter
Reduce the heat to medium-low, add the butter, garlic, and rosemary, and cook for 60 to 90 seconds until the butter foams and smells nutty and the garlic turns pale gold, not brown. Toss everything to coat.
7. Slice and plate
Slice the rested steak against the grain into 1/2-inch strips, catching the juices. Pile the potatoes and peppers on a warm platter, arrange the steak over the top, and spoon the pan juices and garlic butter over everything.
Delicious Variations
Smoky Southwest
Swap the rosemary for 1 teaspoon smoked paprika and 1/2 teaspoon cumin, and finish with lime juice and crumbled cotija.
Mushroom and Herb
Add 8 ounces quartered cremini mushrooms with the peppers for an earthy, meatier platter that stretches the steak further.
Greek-Style
Toss the finished platter with lemon zest, oregano, and crumbled feta, and serve with warm pita instead of bread.
How to Store Cast-Iron Meat and Potato Skillet Platter
Refrigerator
Store leftovers in an airtight container for up to 3 days; keep the steak separate from the vegetables so it doesn't dry out.
Freezer
Freeze the potatoes and peppers only, in a sealed bag, for up to 2 months; the sliced steak becomes mealy when frozen and is best eaten fresh.
Reheating
Reheat the vegetables in a 400F (200C) oven for 8 minutes, then add the steak for the final 2 minutes just to warm through.
Frequently Asked Questions
Q: What is the best cut of meat for a cast-iron skillet platter?
Sirloin is the best all-around choice because it sears to a crust without drying out. Flank steak or ribeye also work well, though ribeye renders more fat that the potatoes will happily soak up.
Q: Can I make this meat and potato skillet in one pan without parboiling?
Yes, but the potatoes will take about 25 minutes instead of 8 and need to be cut into 3/4-inch cubes. Start them first, cook until nearly tender, then remove them while you sear the steak.
Q: How do I know when the steak is done without a thermometer?
Press the center of the steak with your finger: medium-rare feels like the fleshy base of your thumb when your hand is relaxed. For accuracy, a thermometer should read 130F (54C) for medium-rare and 140F (60C) for medium.
Q: Why did my potatoes stick to the cast-iron pan?
They were moved too soon or the pan wasn't hot enough. Let the cut sides sit undisturbed for at least 6 minutes; once a golden crust forms, they release on their own.
Q: Can I use a regular nonstick pan instead of cast iron?
Yes, but you'll get less browning because nonstick pans can't safely reach the same heat. Use a heavy stainless steel skillet as your next best option and add 1 minute to the sear time.
Grab your cast-iron skillet, heat it until it just starts to smoke, and make this platter tonight. Snap a photo of that golden crust and tag me so I can see your version.
