Use freshly shredded cheese
It melts better than pre-shredded cheese and adds richer flavor.

Don’t overmix the cornbread batter
Mix just until combined to keep the topping tender.

Add extra heat if you like spice
You can mix in diced jalapeños, chipotle powder, or hot sauce.

Customize the filling
You can easily add:

• Bell peppers

• Rotel tomatoes

• Green chiles

• Pinto beans

• Jalapeños

Make it extra cheesy
Add another layer of cheese under the cornbread topping.
