Why Cast Iron Is Best for Steak
Cast iron wins because of heat retention and even cooking. Unlike thinner pans, cast iron holds high heat longer. That steady heat creates a better crust and prevents gray, steamed meat.
If you’ve ever compared stainless steel vs cast iron steak, you’ll notice cast iron produces a darker sear and more consistent browning.
It also transitions directly from stovetop to oven, which makes it ideal for thicker cuts.
How to Cook Steak in a Cast Iron Skillet
Here’s the core method used in nearly every professional cast iron steak recipe.
Step 1: Bring Steak to Room Temperature
Let it sit out 30–45 minutes.
Pat completely dry. Moisture prevents proper searing.
Season generously with salt and pepper.
Step 2: Preheat the Cast Iron Skillet
Heat over high for 5–7 minutes.
The pan should be very hot before adding steak.
This step is critical for proper crust formation.
Step 3: Add Oil, Then Steak
Add 1 tablespoon oil.
Place steak down and do not move it.
For a 1-inch steak:
- 3–4 minutes first side
- Flip
- 3–4 minutes second side
This timing is often called the 3-3-3 steak rule, though thickness matters more than timing.
Step 4: Butter Basting
Lower heat slightly.
Add:
- 2 tablespoons butter
- Crushed garlic
- Fresh rosemary or thyme
Tilt the skillet and spoon melted butter over the steak for 1–2 minutes.
This technique builds flavor and enhances the cast iron steak medium rare result.
Cook Time & Temperature
Cooking time depends on thickness, not just minutes.
For precise doneness, always use a thermometer.
If you’re unsure about ideal doneness levels, review our detailed medium rare steak temperature guide.
Steak Temperatures
| Doneness | Internal Temp | Texture |
|---|---|---|
| Rare | 120–125°F | Cool red center |
| Medium Rare | 130–135°F | Warm red center |
| Medium | 140–145°F | Warm pink |
| Medium Well | 150°F | Slight pink |
| Well Done | 160°F+ | No pink |
Remove steak 5°F before target temperature. Rest 5–10 minutes. Resting allows juices to redistribute and improves tenderness.
Steak in Cast Iron Skillet and Oven
For thicker cuts (1.5 inches or more), use the cast iron steak finish in oven method.
When to Finish in Oven
- Bone-in ribeye
- Thick strip steak
- Reverse sear cooking
How to Finish
- Preheat oven to 400°F
- Sear 2–3 minutes per side
- Transfer skillet directly to oven
- Cook 4–8 minutes until target temperature
This method ensures even internal cooking without burning the crust.

Best Oil to Cook Cast Iron Steak
Choosing the right oil matters more than most people think.
You want a high smoke point oil to prevent burning before the crust forms.
Best options:
- Avocado oil
- Grapeseed oil
- Canola oil
Avoid extra virgin olive oil for high-heat searing.
If you want a deeper breakdown of oils and smoke points, see our full guide on
best oil for cooking steak in a pan.
