This Crock Pot corn on the cob recipe has saved me so many times during backyard cookouts when the grill is already piled high. Using the slow cooker leaves your stovetop and outdoor space free and delivers juicy summer corn that comes out perfectly tender every time. With minimal prep and a buttery parsley finish this is my go to for effortless crowd pleasing corn.

I first figured out this crock pot trick during a family BBQ when I underestimated how many cobs we needed. The corn came out so juicy that now my relatives expect this at every summer get together.

Ingredients

  • Fresh corn on the cob: Choose plump ears with bright green husks and golden silk for the sweetest juiciest corn
  • Neutral oil: Brushing oil on the ears helps keep them moist in the slow cooker and enhances the tenderness
  • Salt and black pepper: Light seasoning at first so you can adjust the flavor after cooking
  • Water: Adding a bit of water steams the corn gently to prevent drying out
  • Butter: Soften it before mixing for easier brushing over hot cobs use real butter for the best creamy flavor
  • Fresh parsley: Flat leaf parsley adds a vibrant herbal lift to the buttery glaze chop finely for even coverage

Step by Step Instructions

Prep the Corn:
Remove husks and silk from all corn cobs. Choose ears of similar size so they cook evenly. Pat dry with a clean towel for even oil coating
Season the Corn:
Brush each ear all over with oil using a pastry brush or your hands. Sprinkle lightly with salt and black pepper on all sides to start building flavor
Arrange in the Slow Cooker:
Pour the measured water into the base of your slow cooker about six quarts works well for this batch size. Stack the corn in layers so they fit snugly and are mostly covered by the lid
Cook the Corn:
Set your slow cooker to high. Cover and let the corn steam for anywhere from two and a half to four hours depending on how large or how many ears you have. Listen for that unmistakable sweet corn aroma and check for doneness by piercing a kernel; it should be very tender
Make the Buttery Parsley Glaze:
While the corn cooks stir the softened butter and finely chopped parsley together in a small bowl until smooth
Finish and Serve:
Turn off the slow cooker when the corn is bright yellow and fully heated through. Brush the hot cobs with the herby butter mixture using a new brush or clean spoon. Add extra salt if needed. Serve right away for the tastiest results

I love using sweet summer corn from our local farm stand and my family always gathers around for the first buttery bite. Last summer the kids started calling this sunshine corn which has stuck ever since.

Storage Tips

Leftover corn on the cob keeps well in a sealed container in the fridge for up to three days. Reheat in the microwave wrapped in a damp paper towel. For longer storage cut kernels off the cob and freeze in a resealable bag

Ingredient Substitutions

If you do not have fresh parsley try chives basil or even a little fresh thyme. You can use margarine in place of butter if needed though real butter gives the best flavor. For more zing add a squeeze of lime with the herb butter

Serving Suggestions

Serve the corn as a classic BBQ side with burgers ribs or grilled chicken. For a fun twist sprinkle with crumbly cheese like cotija or feta and a dash of chili powder. Kids love it just with a big pat of butter

Cultural and Historical Note

Corn on the cob is a classic symbol of summer all over North America. Slow cooking it is a fairly new trick but the tradition of sharing sweet corn at gatherings goes back to Indigenous peoples who have grown and treasured maize for thousands of years

Recipe FAQs

→ Can I leave the husks on the corn?

It's best to husk and clean the corn before adding it to the slow cooker. This ensures even cooking and allows the flavor of the butter to soak in.

→ How do I know when the corn is done?

Corn is ready when the kernels are bright yellow and fully tender. Start checking after 2.5 hours on HIGH, as cook time may vary.

→ Can I use frozen corn cobs?

Yes, frozen ears can be used. Cook time may increase slightly, so check tenderness as it cooks.

→ What can I use instead of parsley?

Fresh chives, dill, or cilantro make flavorful alternatives if you want to change up the herb glaze.

→ How long can corn stay warm in the slow cooker?

Once finished, you can keep corn on the warm setting for up to 30 minutes without losing quality.
