What is blackened corn?
Blackened corn is corn that has been seasoned and cooked in a very hot pan until parts of it char and darken. The browning and light charring give a smoky, toasty flavor and bring out the natural sweetness. It is usually done in a cast-iron skillet or on a grill. This guide covers the stovetop version, which works well when you do not have a grill. “Blackened” and “charred” corn are essentially the same technique here; blackened versions often add a spice blend.
What you need
- Corn: kernels (fresh, frozen) or ears of corn
- A cast-iron skillet, or another heavy skillet
- A little oil with a high smoke point, such as avocado oil, or butter
- Salt and pepper, or a blackening seasoning
- Tongs or a spatula
- A kitchen vent or open window
Blackened corn kernels in a skillet
This is the fastest route.
- Dry the corn. Pat the kernels dry with paper towels. Frozen corn does not need to be thawed, but it releases more water, so give it a little extra time.
- Heat the skillet over medium-high heat. Add a small amount of oil or butter, or use a well-seasoned cast-iron skillet with very little fat (the same seasoning principles as a wok apply).
- Add the corn in an even layer. Press it down gently.
- Leave it alone for about 2 to 3 minutes so a crust can form.
- Stir and repeat. Stir, spread it out again, and cook another few minutes until you see dark brown and black spots. Corn may pop a little as it cooks.
- Season with salt, pepper, and spices, then serve.
Total time is typically around 10 to 15 minutes, depending on the pan, heat, and how charred you like it.
Blackened corn on the cob on the stove
For ears of corn:
- If starting from raw fresh corn, some cooks boil the ears for about 3 to 4 minutes first so the corn is mostly cooked, then drain and dry them well.
- Rub the corn with oil or butter and your spice blend.
- Heat a skillet over medium-high heat and add the corn.
- Turn every 2 to 3 minutes until charred on all sides.
- Finish with a little butter, then cut the kernels off the cob if you like.
Use a skillet large enough to hold the ears, or cut ears in half. Use tongs because the corn gets very hot.
Homemade blackening seasoning
A simple mix, adjusted to taste, might include:
- Smoked paprika
- Garlic powder
- Onion powder
- Salt and black pepper
- Cayenne pepper (optional, for heat)
- Dried oregano or thyme
You can swap in store-bought Cajun or blackening seasoning. Taste your blend first, as salt content varies.
The secret to good char
- Dry corn: Wet kernels steam rather than brown.
- Hot pan: Let the skillet heat up before adding corn.
- Do not stir constantly: Letting the corn sit gives it time to char.
- Do not overcrowd: Use a large pan, or cook in two batches.
- Add the spices later: Spices can scorch quickly and turn bitter if added too early at high heat. Add them partway through.
Fresh, frozen or canned corn
- Fresh: Cut kernels from the cob, or cook the ears directly.
- Frozen: Works well and does not need to be thawed first, though it may take longer.
- Canned: Drain very well and pat dry. Some cooks find the texture less satisfying than fresh or frozen corn.
Managing smoke
Charring makes smoke by design. Turn on the exhaust fan, open a window, and keep the heat from going too high. If the pan is smoking heavily, lower the heat slightly, and consider a lid for brief moments if kernels begin to pop out. Stay near the stove while cooking.
Serving ideas
Use blackened corn in tacos, burrito bowls, salads, salsas, chili, quesadillas, scrambled eggs, or as a side with grilled meats (see our charcoal grill tips) and fish. Finish with lime, herbs, or crumbled cheese.
Storing and reheating
Cool leftovers and store them in a covered container in the refrigerator for a few days. Reheat in a skillet or microwave, or serve cold in salads.
