Few summer pleasures compare to the simple joy of biting into a warm, buttery ear of corn on the cob. Whether you’re enjoying it at a backyard picnic, a family barbecue, or a quiet dinner at home, perfectly cooked corn is sweet, tender, and just the right amount of juicy.
But if you’ve ever found yourself wondering, “How long do I boil corn on the cob?”—you’re certainly not alone.
Boil it too long, and it becomes tough and chewy. Not long enough, and it’s undercooked and starchy. Fortunately, cooking corn to perfection is easier than you might think—once you know the right timing and a few simple tips.
This article is your complete corn boiling timing guide, tailored for home cooks of all skill levels. Whether you’re cooking for two or feeding a crowd, we’ll help you boil corn on the cob just right—every single time.
Why Boiling Corn Is Still the Best Method
There are several ways to cook corn—grilling, roasting, even microwaving. But boiling remains one of the easiest, most reliable ways to cook corn evenly and quickly.
It requires no special equipment, keeps the kernels tender, and brings out that naturally sweet flavor—especially in fresh sweet corn picked at its peak.
If you’re over 60 and cooking smaller portions, boiling is also a gentle and low-effort method that doesn’t require standing at a grill or lifting heavy pans in and out of the oven.
How to Prepare Corn for Boiling
Before we dive into timing, here’s how to prepare your corn:
Step 1: Husk the Corn
Peel away the green husks and remove the silky strands underneath. You can do this over the sink or even outside if you’re dealing with multiple ears.
Step 2: Trim if Needed
If the ends are uneven or too long for your pot, trim the stalk with a sharp knife.
Step 3: Fill Your Pot
Use a large pot and fill it with enough water to fully submerge the corn. Don’t salt the water yet
The Ideal Boiling Time for Corn on the Cob
Fresh Corn (Right Off the Cob): 3–5 Minutes
If you’ve just bought fresh-picked corn or harvested it yourself, congratulations—this is the best type of corn to boil. It’s tender and naturally sweet.
- Bring your water to a rolling boil.
- Add the corn and cover the pot.
- Boil for 3 to 5 minutes. Any longer and it may become overcooked.
- Remove with tongs and let it cool slightly before serving.
Older Corn or Supermarket Corn: 6–8 Minutes
If your corn has been sitting in the fridge a couple of days or you bought it pre-packaged at the store, it’s still delicious—but may need a few more minutes.
- Bring water to a full boil.
- Add corn, cover the pot.
- Boil for 6 to 8 minutes. This softens the starches and revives the flavor.
- Check for tenderness with a fork if unsure.
Frozen Corn on the Cob: 8–10 Minutes
Yes, you can boil frozen corn without thawing it first! Just add a little time to the process.
- Place frozen corn directly into boiling water.
- Don’t thaw beforehand—it’s unnecessary.
- Boil for 8 to 10 minutes, or until heated through.
Tips for Perfectly Cooked Corn Every Time
1. Don’t Overcrowd the Pot
Corn needs room to circulate in the water. If you’re cooking several ears, use a large stock pot or cook in batches.
2. Use a Lid
Once you add the corn, put the lid on. This brings the water back to a boil faster and ensures even cooking.
3. Avoid Overcooking
Even just a few minutes too long can turn sweet, snappy kernels into mushy, chewy ones. Stay nearby and set a timer if needed.
4. Season After Cooking
Salt or butter added before boiling can cause corn to toughen. Instead, add your toppings after cooking for best flavor and texture.
Pro Tip: Add a Splash of Milk and Butter to the Water
Here’s a beloved Southern secret for extra flavorful corn: add a splash of milk and a few tablespoons of butter to the boiling water.
- This enhances the corn’s natural sweetness.
- It gives the kernels a richer, creamier finish.
- Simply add to the water before placing in the corn.
Try it once—you’ll be hooked.
How to Know When Corn Is Done
Here are a few signs your corn is perfectly boiled:
- The color deepens—yellow corn becomes more golden, and white corn takes on a creamier tone.
- The kernels look plump and slightly shiny.
- A fork should easily pierce the kernel without resistance.
And most importantly? Taste one. That’s the cook’s privilege.
Storing and Reheating Leftover Corn
Boiled more than you need? Don’t worry—cooked corn stores beautifully.
To Store:
- Wrap leftover ears in foil or plastic wrap.
- Keep in the refrigerator for up to 3 days.
To Reheat:
- Boil briefly for 1–2 minutes, or
- Microwave with a damp paper towel for 30–60 seconds.
Or slice off the kernels and toss them into salads, soups, or casseroles.
