Wonderful creamy casserole. I made 1/2 the recipe & baked in an 8X8 pan. Minor changes - I added a can of diced green chilis & a dash of smoked paprika to give it some zip & used canned corn rather than frozen . I realized after baking that I had forgotten the milk but it was still moist & delicious. Excellent change from my usual boring side dishes! Thanks!
What a great casserole, reheats well in the microwave also. I will definitely make it again. I used Vidalia onions they were delicious in it. thankyou for sharing.
When you start hiding leftovers from your loved ones, you know you've found a great recipe. This onion-corn casserole is outstanding. Easy to make and super good. I didn't have Mexican cheese so grated Monterey Jack and cheddar. I also substituted a can of corn for the frozen corn. Don't even look at the nutritional info. This is worth the calories and carbs.
