This recipe is built around a simple idea: a screaming-hot cast iron skillet does two jobs in a row. First it sears a thick strip steak to a deep mahogany crust, then those same browned butter-and-beef drippings get tossed with sliced bell peppers until they soften and char at the edges. The plate you end up with looks like a steakhouse order, but it comes out of one pan in under an hour.

The herb butter is the quiet hero. It's mashed together while the steak rests, then melted over the hot slices so it runs into every crevice instead of sitting on top. A cutting board of sliced meat and blistered peppers next to a clean white plate is genuinely all the presentation you need.
Buy a steak at least 1 1/4 inches thick so it can build a crust without overcooking. Thin supermarket steaks will hit medium before they brown, which is the single biggest reason home steak falls flat.

About the Ingredients
2 (about 1 1/2 lb / 680g total) boneless strip steaks, 1 1/4 to 1 1/2 inches thick
New York strip has the best fat-to-lean balance for searing; ribeye works if you want more marbling, and sirloin is the leaner swap but needs 1 minute less per side.
1 1/2 teaspoons kosher salt
Use Diamond Crystal; if you only have table salt, cut it to 1 teaspoon because the crystals are much denser.
1 teaspoon coarsely ground black pepper
Fresh-cracked from a grinder tastes far brighter than pre-ground; a coffee grinder on the coarsest setting works in a pinch.
1 tablespoon neutral oil with a high smoke point, such as avocado or canola
Skip olive oil here, it will smoke and turn bitter at searing heat; grapeseed oil is a good substitute.
3 medium bell peppers (red, yellow, and orange), seeded and cut into 1-inch strips
Mixed colors look best, but all-red is fine; poblanos are a great swap if you want a mild smoky heat.
4 tablespoons (56g) unsalted butter, softened
Let it sit out 30 minutes; salted butter works, just drop the finishing salt by half.
2 garlic cloves, finely grated
A microplane gives you garlic that melts into the butter; 1/2 teaspoon garlic paste is the shortcut.
2 tablespoons finely chopped fresh parsley
Flat-leaf parsley has more flavor than curly; fresh thyme leaves or torn basil also work well.
1 teaspoon fresh lemon juice
Bottled lemon juice is too flat here; a splash of red wine vinegar is a sharp, punchy substitute.
Flaky sea salt, for finishing
Maldon gives the best crunch; coarse kosher salt is an acceptable stand-in.
Tips & Tricks
- Dry the steak thoroughly with paper towels and salt it 40 minutes ahead if you can. Surface moisture is the enemy of browning, and the early salt draws moisture out so the pan stays hot.
- Preheat the cast iron for a full 5 minutes over medium-high before the meat goes in. A pan that is still climbing in temperature will steam the steak instead of searing it.
- Do not crowd the peppers. If your skillet is smaller than 12 inches, char them in two batches so they blister instead of turning soft and gray.
- Slice against the grain and let the steak rest a full 8 minutes. Cutting too early dumps the juices onto the board instead of keeping them in the meat.
Pro Tips
Step-by-Step Instructions
1. Dry and Season the Steak
Pat the steaks completely dry with paper towels, then season all over with the kosher salt and black pepper. Let them sit at room temperature for 20 minutes while you prep everything else.
2. Make the Herb Butter
Mash the softened butter with the grated garlic, chopped parsley, and lemon juice until evenly combined. Scrape it onto a small plate and chill while you cook.
3. Heat the Cast Iron
Set a 12-inch cast iron skillet over medium-high heat for 5 minutes, then add the neutral oil and swirl. The oil should shimmer and move like water, not smoke heavily.
4. Sear the First Side
Lay the steaks in the pan away from you and do not move them for 4 minutes. They are ready to flip when a deep brown crust releases easily and the edges look caramelized.
5. Flip and Butter-Baste
Flip the steaks and cook 3 to 4 minutes more, adding 1 tablespoon of the herb butter and spooning the foaming butter over the meat. Pull them at 125F (52C) internal for medium-rare.
6. Rest the Meat
Transfer the steaks to a cutting board and tent loosely with foil for 8 minutes. Leave the browned butter and drippings in the skillet.
7. Char the Peppers
Add the pepper strips to the hot skillet over medium-high heat and cook 6 to 8 minutes, stirring every 90 seconds, until the edges blister and soften. They are done when they smell sweet and show dark char spots.
8. Slice and Plate
Slice the steak against the grain into 1/2-inch strips, spread the charred peppers on a warm white plate, top with the steak, and dot with the remaining herb butter and flaky salt.
Delicious Variations
Smoky Chipotle Version
Stir 1 teaspoon of adobo sauce into the herb butter and finish the peppers with a squeeze of lime instead of lemon.
Mushroom and Onion Skillet
Swap the bell peppers for 8 ounces of sliced cremini mushrooms and one sliced onion, cooking 2 minutes longer.
Chimichurri Steak
Skip the compound butter and spoon a bright parsley-garlic-vinegar chimichurri over the sliced steak instead.
How to Store Skillet Steak with Charred Peppers and Herb Butter
Refrigerator
Store leftovers in an airtight container for up to 3 days; keep the peppers separate from the steak so they do not get soggy.
Freezer
Freeze sliced steak in a freezer bag with the juices for up to 2 months; the peppers do not freeze well and are best eaten fresh.
Reheating
Reheat the steak gently in a 300F (150C) oven for 6 to 8 minutes or just until warm, and re-crisp the peppers in a dry skillet over medium-high heat for 2 minutes.
Frequently Asked Questions
Q: How do I know when the steak is done without a thermometer?
Press the center of the steak with your fingertip and compare it to the base of your thumb: medium-rare feels like a relaxed thumb pad, firm but springy. A thermometer is still the reliable answer, so pull at 125F (52C) for medium-rare.
Q: Can I make this recipe in a regular nonstick pan?
Yes, but you will get a lighter crust because nonstick pans cannot take the same high heat. Use a heavy stainless steel or cast iron skillet if you have one, and never heat a nonstick pan above 450F (230C).
Q: Why did my peppers turn out soggy instead of charred?
The pan was likely overcrowded or not hot enough when the peppers went in. Cook them in two batches in a 12-inch skillet over medium-high heat and give them space to blister rather than steam.
Q: What should I serve with skillet steak and charred peppers?
Crusty bread, roasted potatoes, or a simple arugula salad all work well because they soak up the herb butter. Keep sides mild so the charred peppers stay the star.
Q: Can I use frozen steak for this recipe?
Yes, but thaw it fully in the refrigerator overnight and dry it well before seasoning. Cooking from frozen prevents the crust from forming and throws off the timing completely.
