Grandma Coco’s Famous Chile Relleno Casserole

Sharing is caring!

My Mom has made this Chile Relleno Casserole for as long as I can remember. It is a very simple recipe with layers of chiles and cheese surrounded by eggs, and the chiles are mild and have such a wonderful flavor. This dish is great for breakfast, lunch, or dinner!

Grandma Coco (my Mom) makes this in a 9×13-inch stoneware pan. The stoneware is great because it keeps the casserole nice and warm when serving. You can definitely make it in any pan you have though.

Here’s what you need to make Grandma Coco’s Chile Relleno Casserole:

  • 12 eggs
  • 3/4 cup milk
  • 1 tsp salt
  • 11 oz can green chiles + 7 oz can green chiles
  • 5 cups shredded cheddar cheese
Can of HATCH brand whole green chilis.
These are the green chilies that Grandma Coco uses.

Let’s make it:

Start by buttering your dish and add a layer of chiles on the bottom. Lay the chiles flat and use half of them for this layer. You will want to remove the seeds first to keep the dish mild.

Next layer about half of the cheese over the chiles.

Blend the eggs with the milk and salt and pour it over the top of the chiles and cheese.

Next top the chile relleno casserole with the remaining cheese and cover with foil. Bake at 350 degrees for 40 minutes, then uncover and bake for another 5 minutes until the cheese is golden brown.

I have to say this is an amazing recipe. I need to say I have given it a twist. I chopped some onion about 1/2 and added 2 1/2 cups of rotisserie chicken from Walmart. Then I used 6 eggs instead of 12 and put 1/2 Cup of milk. I blended the milk and eggs for two minutes.

We like it as breakfast or supper main dish with cooked breakfast sausage layered between the chiles. Top each serving with a spoonful of fresh red chile puree and so good!

Great casserole with so many options to add to this recipe. Try adding cooked chicken, or a layer of rice, or corn, or any combination of the 3. Stretches the casserole and makes it a complete meal.
