Creamy Corn Polenta with Grilled Sweet Corn

As much as I love meat, I’ll admit man can’t live on meat alone. OK, I probably could, but a great side dish is what turns a good steak into a complete meal. And this creamy corn polenta has been in my rotation longer than almost anything else on this site.

I didn’t grow up eating polenta. I’d never even heard of it until a server at a steakhouse talked me into ordering it as a side, and I was skeptical right up until the first bite. It was creamy and rich with just the right touch of sweetness, and I’ve been hooked ever since.

I went home and started working on my own version, and after a few rounds of trial and error I made it mine. This spicy sweet corn polenta, as I originally called it back in 2017, gets grilled sweet corn for smoky flavor, plenty of Parmesan, and a hit of cayenne to keep things interesting.

Why This Recipe Works

Grilling the corn in the husk is the move that separates this from every other polenta recipe out there. The husk steams the kernels while the grill adds a subtle roasted flavor you just can’t get from a pot of boiling water. That smoky sweetness carries through the whole dish.

The polenta itself cooks in a mix of chicken OR veggie stock and water instead of plain water. That builds a savory backbone before the butter, cream, and Parmesan even show up. 

And finishing it under the broiler in a cast iron skillet gives you a browned, bubbly Parmesan crust on top of all that creamy goodness underneath. Two textures, one pan, and it comes to the table looking like a steakhouse side.

About the Ingredients

Corn grits (polenta). This is the one ingredient where you can’t improvise. Buy corn grits or coarse cornmeal specifically labeled for polenta, not the fine cornmeal you’d use for baking. Fine cornmeal turns into a gluey paste instead of that creamy, slightly toothsome texture you’re after.

Fresh corn. Six to eight ears of fresh sweet corn, grilled in the husk. If corn is out of season, 16 ounces of frozen sweet corn works. I cover exactly how in The Shortcut Version section below.

Parmesan cheese. Nine ounces of shredded Parmesan, split between the polenta and the broiled top. Grab a wedge and shred it yourself if you can, since pre-shredded cheese is coated in anti-caking agents that don’t melt as smoothly.

Heavy cream and butter. Half the cream goes in while the polenta cooks, the rest gets stirred in at the end with the butter. That two-stage approach keeps it silky instead of heavy.

Cayenne pepper. Two teaspoons gives it a warm, building heat that plays off the sweet corn. It’s optional, but the spicy sweet contrast is what makes this dish memorable. Dial it up or down to your taste.

Chicken OR veggie stock. Three cups, combined with three cups of water. All stock is too rich and muddies the corn flavor, all water is too flat. The split is the sweet spot.

Why I Grill the Corn

You can absolutely roast the corn in the oven, but I’m almost always grilling the main course anyway, so the grill is already hot. Might as well put it to work.

Grilling the ears in their husks is what makes this work. The husk acts like a built-in steamer, trapping the corn’s natural moisture so the kernels come out juicy while picking up a gentle roasted flavor from the grill. That flavor carries into every bite of the finished polenta.

You’ll see plenty of recipes that call for soaking the corn in water first. I used to do it too, but I’ve roasted corn with and without soaking, more times than I can count, and I skip the soak now. The husk holds plenty of moisture on its own over indirect heat, and you get 30 minutes of your life back.

Twenty minutes over indirect heat at 350°F is all it takes. When the corn is cool enough to handle, the husks peel right off and you’re ready to cut the kernels.

How to Make Creamy Corn Polenta

Step 1: Fire up the grill. Heat your grill to 350°F and set it up for indirect cooking. The oven works too, but the grill is where the flavor is.

Step 2: Roast the corn. Place the ears on the grill, still in their husks, over indirect heat for 20 minutes.

Step 3: Cut the kernels. Let the corn cool enough to handle, then remove the husks and cut the kernels off the cob. Set them aside.

Step 4: Start the polenta. While the corn roasts, combine 3 cups of chicken OR veggie stock, 3 cups of water, and 1 tablespoon of kosher salt in a large saucepan.

Step 5: Add the grits. Bring the liquid to a boil, then gradually whisk in 2 cups of polenta and ½ cup of the heavy cream.

Step 6: Simmer low and slow. Reduce the heat to low and simmer for 30 minutes, stirring frequently. Polenta will scorch if the heat’s too high or you walk away from it, so keep an eye on it. You’re looking for the consistency of thick mashed potatoes.

Step 7: Make it rich. Stir in the butter, 5 ounces of the Parmesan, and the remaining ½ cup of heavy cream until fully blended.

Step 8: Add the corn and heat. Fold in the grilled corn kernels and the cayenne until evenly distributed. Taste it here and adjust the salt.

Step 9: Broil it. Transfer everything to a cast iron skillet, top with the remaining Parmesan, and broil until the cheese is melted and browned in spots.

Step 10: Serve. Finish with a small pinch of cayenne for color and bring the whole skillet to the table.

Tips for Perfect Polenta

Stir more than you think you need to. Polenta thickens from the bottom up and will stick and scorch the second you get distracted. Low heat and a frequent stir are non-negotiable.

Season the liquid, then adjust at the end. Polenta absorbs salt while it cooks, so the tablespoon up front is a must. But hold any extra until the end, since the Parmesan and stock bring their own.

Don’t skip the broil. Even 3 or 4 minutes under the broiler transforms the top layer of cheese into a golden crust, and serving it straight from the cast iron keeps it hot at the table.

If cayenne isn’t your thing, garnish with paprika instead. You won’t get much heat or flavor from it, but the color pop makes for a much better looking dish.

The Shortcut Version

No shame in taking the fast lane on a weeknight. Swap in 16 ounces of frozen sweet corn and skip the grilling steps entirely. Thaw the corn, pat it dry, and fold it in at Step 8 right along with the cayenne.

You can also start with pre-cooked polenta in a tube, sliced and warmed with the stock and cream until smooth. I’ve done it both ways and the shortcut version is still good, just not as good. The grilled fresh corn is doing real work here.

What to Serve It With

Creamy polenta and beef were made for each other, which is exactly how I discovered this dish in the first place. It’s outstanding under a sliced London Broil, where the polenta catches all those juices.

It also holds its own next to grilled chicken. Try it alongside my Hot Honey Chicken Thighs where the creamy corn cools down the hot honey heat.

And if you’re smoking pork, this is right up there with mac and cheese as the creamy side.
