The onions soften just enough to mellow their bite, while the corn stays crisp-tender – it’s absolute perfection with just a pat of butter melting over everything.

Notes

I’m all about recipes that don’t keep me chained to the stove, and this corn onion boil delivers. While the water comes to a boil (about 5 minutes), you’ve got just enough time to husk the corn and slice the onion. Then it’s just 10 minutes of simmering while you finish setting the table or tossing a salad. The butter-and-seasoning step takes maybe 2 minutes – that’s it! Perfect for when hunger strikes and patience is thin.
Budget-Friendly Ingredients
Let’s be real – fresh corn and onions are some of the most affordable produce you can buy, especially in summer. I’ve made this with $0.25 ears of corn from roadside stands and it tastes just as amazing as pricier supermarket corn. The onions stretch far too – one large onion flavors the whole batch beautifully. When I’m feeding a crowd, this is my secret weapon for keeping costs down without sacrificing flavor.
Corn Onion Boil Ingredients
Here’s all you need to make this simple yet flavorful dish, trust me, you’ll be amazed at what these basic ingredients can do together:
- 4 ears fresh corn, husked and cut into thirds (that perfect bite-sized piece!)
- 1 large onion, sliced nice and thin so it cooks evenly

- ½ teaspoon salt, just enough to make all the flavors pop
- ¼ teaspoon black pepper, for that little kick at the end
See? I told you it was simple! Now let’s get cooking.
How to Make Corn Onion Boil
Okay, let’s get cooking! This corn onion boil comes together so easily, you’ll wonder why you haven’t been making it every week. I’ve made this dozens of times, and I’ve got the timing down to a science, follow these simple steps for perfect results every time.
Boiling the Corn and Onion
First, grab your biggest pot, I use my trusty 6-quart Dutch oven, and fill it about halfway with water. Set it over high heat and let it come to a rolling boil (this usually takes me about 5 minutes). While you’re waiting, toss in your corn pieces and onion slices, the water should just cover them. Don’t worry if some corn floats at first!
Once it’s boiling, reduce the heat to medium, you want a nice gentle simmer, not a furious boil. Set your timer for exactly 10 minutes, this gives the corn time to soften while still keeping that perfect crisp-tender bite we love.
Adding Butter and Seasoning
Here’s where the magic happens! Drain the water completely (careful, it’s hot!) and return the corn and onions to the warm pot. Now add your butter, I like to cut it into small pieces so it melts faster. Sprinkle in the salt and pepper, then give everything a gentle stir with a wooden spoon.
The residual heat from the pot will melt the butter beautifully, coating every piece with that rich, savory goodness. I usually let it sit for about a minute off the heat, just long enough for the flavors to mingle but not so long that the corn gets mushy.
And that’s it! You’ve just made the easiest, most delicious corn onion boil. Now try not to eat it all straight from the pot (no judgment if you do, I’ve been there!).
Tips for the Best Corn Onion Boil
After making this corn onion boil more times than I can count, I’ve picked up some tricks that take it from good to “oh-my-goodness-where-has-this-been-all-my-life” amazing:
- Fresh is best, Seriously, the corn makes all the difference. Look for ears with bright green husks and plump kernels that burst when you press them.
- Slice onions thin, About ¼-inch thick lets them soften just right without disappearing into the broth.
- Watch the salt, Start with half the amount and add more at the end if needed. The butter brings its own saltiness!
- Don’t overcook, Set that timer! Ten minutes keeps the corn perfectly crisp-tender.
Oh, and here’s my secret, I always make extra because leftovers disappear fast!
Corn Onion Boil Variations
One of my favorite things about this corn onion boil is how easily it adapts to different diets without losing any of its deliciousness! Here are the simple swaps I’ve tested that work beautifully:
- Keto version: Use just 2 ears of corn and double the butter, still gets that sweet corn flavor without all the carbs
- Dairy-free: Swap regular butter for ghee or olive oil, adds a lovely richness without dairy
- Extra flavor: Toss in a minced garlic clove or pinch of red pepper flakes with the butter
See? Even with tweaks, it’s still that same comforting dish we love! If you enjoy experimenting with flavors, you might also like trying out a brown butter onion boil recipe for a deeper nutty flavor.
Serving Suggestions for Corn Onion Boil
This corn onion boil is like the ultimate team player at mealtime, it goes with practically everything! My absolute favorite way to serve it is alongside juicy grilled chicken or burgers hot off the barbecue. The sweet corn and buttery onions balance out smoky flavors perfectly.
For lighter meals, I’ll pair it with a crisp green salad and some crusty bread, instant summer feast! It’s also fantastic with baked fish or pork chops when you want something simple but special. Honestly, I’ve even eaten it straight from the bowl as a snack (don’t tell anyone!).
Storing and Reheating Corn Onion Boil
Here’s the good news, this corn onion boil keeps beautifully! Just let it cool completely, then pop it in an airtight container in the fridge for up to 3 days. When you’re ready to enjoy it again, I’ve found the microwave works best, just 60 seconds on high brings back that fresh-off-the-stove taste. If you’re reheating a larger portion, sprinkle a tablespoon of water over the top first to keep everything moist. Trust me, it tastes just as good the second day, if it lasts that long!
Corn Onion Boil Nutrition
Let’s talk numbers, but don’t worry, I promise this corn onion boil won’t wreck your diet! One serving (about 1 cup) comes in at around 120 calories, with most of that coming from the natural sweetness of the corn and that glorious butter. Here’s the breakdown per serving:
- 18g carbs, mostly from the corn’s natural sugars
- 3g protein, not bad for a veggie side!
- 6g fat, thank that delicious butter
- 2g fiber, corn and onions working together
Now, here’s my kitchen truth, these numbers can change based on your exact ingredients. Maybe your corn is extra sweet, or you go heavy on the butter (no shame!). Nutritional values are estimates and vary based on ingredients. But honestly? When something tastes this good and comes together this easily, I’m not counting too closely!

Corn Onion Boil FAQs
Can I use frozen corn instead of fresh?
Absolutely! While fresh corn gives the best texture, frozen corn works in a pinch. Just add it straight from the freezer, no need to thaw first. You might want to reduce the boiling time by 2-3 minutes since frozen corn tends to be more tender.
How can I make this corn onion boil spicier?
I love adding a kick sometimes! Toss in a pinch of red pepper flakes with the butter, or stir in a diced jalapeño when you add the onions. My husband swears by a dash of hot sauce at the end, it’s delicious!
Can I prepare this ahead of time?
You sure can! Cook everything except the butter step up to a day in advance. When ready to serve, just reheat the corn and onions, then stir in the butter and seasonings. The flavors actually deepen overnight, it’s one of those rare dishes that gets better as it sits!
