    My favorite breakfast recipe EVER: Chile Relleno Casserole. This beloved recipe has received a lot of feedback, good and bad, read below to see why!

    Chile Relleno Breakfast Casserole is a morning casserole with eggs, two types of cheese, and mild green chiles. A perfect breakfast recipe for feeding a crowd!

    Chile Relleno Breakfast Casserole is a family, neighbor, and Pinterest favorite! Well, for the majority of folks.

    There are a lot of haters out there too. It’s okay, I have thick skin. But if you are a hater, read on for my answers to your burning chile relleno casserole questions…

    Bowl of whole green chiles

    This egg bake uses two pounds of cheese, yes TWO! It is super cheesy, but bakes nicely into the egg to add flavor and texture rather than being stringy or overindulgent.

    Patty says: “This recipe is amazing. I have made it 4 times already. Did it for Easter brunch. I did change it up a little. I used Mexican cheeses.

    Which work so much better. Not a grease. And I even put chorizo in it own time. I recommend this recipe you won’t be disappointed.”

    If you still think it is too much cheese, then reduce it to one pound. I guarantee you’ll miss the missing cheese. The cheese is really what makes this casserole.

    And the chile… LOL. Now a lot of folks have commented here and Facebook that two pounds of cheese is just TOO much cheese.

    I promise you, it is not. After you pop it in the oven, you won’t even get super cheesy pieces. Not any more than other breakfast casseroles, at least.

    Susan says: “This was absolutely fabulous . Everyone loved it . I used canned HATCH chilies , used 6 eggs rather than five, and increased the flour and milk by a tablespoon”

    I try to make Chile Relleno Casserole only when we have guests in town due to the copious amounts of cheese.

    Only because despite my defense on oodles of cheese, I do try to eat fairly healthy on a regular basis and only allow dishes like this on special occassions

    Is there really such a thing? And if you actually make the recipe, you’ll see that although it is one heck of cheesy recipe, you hardly notice when you are eating it.

    Susan B. says: “Super easy. Very yummy. One of my hubbies favorites.”

    I also get some individuals who think that this casserole is more of a green chili egg casserole, like a pork chili verde, but really it is just green chiles (I use poblano peppers).

    Make ahead breakfast casseroles are perfect for feeding large groups. The chile is mild enough to not be spicy and it also vegetarian-friendly. (NOT vegan, many vegetarians are lacto-ovo).

    Bowl of shredded cheddar cheese

    In some areas you can even buy mild or hot chiles to your preference. 

    And if you are a carnivore, you can easily have some meat on the side. Candied Bacon and Homemade Breakfast Sausage are good bets. Even just heat up some ham.

    Joy says: “I love this recipe! It is great for any meal. I also like that I can reduce it down to 2 servings.”

    You can even add cooked, crumbled breakfast sausage, ground beef or bacon right into your Chile Relleno Casserole. Shredded chicken also works nicely.

    Many of our readers have tried and loved these variations!

    We are very aware that this delicious breakfast casserole recipe is NOT a real chile relleno. And that chile rellenos are battered and fried. We get it. 

    This is a deconstructed chili relleno. The original recipe appeared in a Junior League cookbook in Denver, Colorado and claimed to be from an authentic Mexican family. 

    Past that, I can’t authenticate it. And I’ve never claimed it to be an authentic Mexican recipe or any other type of Mexican food.

    So before you throw stones, I didn’t name it either. All I know is that this make ahead breakfast casserole is delicious! And if you try it, you’ll probably agree.

    And the last bashing it gets is if it is a chile relleno or chili relleno. Geez, the “i” or the “e”.

    Well, my friend who is an editor claims that the chile pepper is indeed with an “e” and the soup is with an “i”.

    Cheryl says: “Delicious! I used almond flour and gypsy peppers as I couldn’t find chili peppers. It was very mild and quite tasty!”

    Call it a chili Relleno Casserole if you’d like. It still tastes the same!

    The original recipe for Chile Relleno Casserole calls for whole green chiles, however, these seem to be more and more difficult to find.

    You can substitute those for three 4.5-ounce cans of chopped green chiles. Be sure to drain well and dry on a paper towel to reduce moisture.

    Gina says: “I’m all about a recipe that calls for 2lbs of cheese and yes it IS required in this dish. We love chile rellenos but I always wind up with a greasy, soggy mess.

    I let the top brown a little and get crispy, mmmm. This is a perfect deconstructed chile relleno recipe!”

    You can also use fresh chiles, if they are in season or your grocer carries them.

    I use a mild chile, but you can, of course, also pick a hot variety.

    Instead of using “fingers of cheese” to stuff the chiles, chop the cheese into 2-inch cubes. If I am feeding more than 12, I will add a few more eggs. No additional measurement changes are necessary.

    Marlene says: “This recipe always gets raves for our annual breakfast buffet. It is perfect And is always a big hit!”

    And the last most asked question for my Chile Relleno Casserole: Can you freeze chile relleno casserole or make it ahead of time? The answers are yes and yes.

    You can make Chile Relleno Casserole the night before you intend to bake it. It might take a few more minutes in the oven to come to temperture seeing that it will be chilled instead of room temperature. Use your best judgment.

    John says: “This has become a family and friend favorite. It is so easy to make!”

    If you freeze this casserole, cook it, then freeze it in small batches with as little air as possible.

    Wrap in aluminum foil or freezer paper, then in an airtight bag. It should be good for up to 3 months. Also see our guide to freezing food, or more specifically how to freeze a casserole!

    9 x 13 Glass Baking Dish– an absolute essential for any kitchen! Use it for baking, marinating or storing. Get one with a lid, you’ll thank me later.

    Questions you might have about how to make chile relleno breakfast casserole: 

    Can I omit the flour? You can omit the flour, it helps the eggs stay a little fluffier, but isn’t necessary for the recipe to be successful. 

    What type of chile can I use? Many folks have successfully made this recipe with many varieties of chiles, so the answer is ANY! I like to use mild green chile or roasted Hatch chile.

    Others have used poblano pepper, although they tend to have a thicker skin so are better when charred and skinned, jalapenos and even ghost peppers. 

    Cheese and green chiles in a baking dish

    Can I reduce the amount of cheese? I agree, it seems like a lot of cheese, but I can promise you that after it bakes, it won’t be a steaming dish of melted cheese (although I wouldn’t be opposed to that).

    Read a few of the comments and the cheese, they have vouched for me. That said, if you want to reduce the cheese, be my guest! 

    What types of cheese can use in this chile relleno casserole? I use pepper jack, colby and cheddar cheeses, but you can use whatever mix you’d like.

    PRO TIP: Use freshly shredded cheese. Pre shredded cheese is great for so many things, but it lightly coated with a powdered starch to keep it from clumping. This can impact its meltability factor. 

    Cheddar pepper jack,  jalapeno cheese, white cheddar, cotija, monterey jack cheese, queso fresco or any combination of them is alright by me! Some folks even go one step further and serve the cooked casserole with a side of cottage cheese.

    Can I add meat to this breakfast casserole? You are more than welcome to add a protein! The only key is to make sure it is cooked and drained before you add it. Bacon, sausage and ham seem to be the most popular. 

    Why do you add ground mustard? It just adds a little but of flavor. You can also use a dab of Dijon mustard or even yellow mustard. That little bit of acid will elevate the dish. You can certainly omit it if you like or don’t have it on hand. 

    Can I freeze chile relleno casserole? You sure can! Make sure to package it correctly for the freezer and it will store for 3-4 months. 

    Can I make this green chile egg casserole into egg muffins? You sure can. Shred all of the cheese and used diced chiles instead of whole. Bake in a muffin tin on 350 for 12-15 minutes, or until the centers bounce back easily. 

    Is chile relleno casserole gluten free? If you omit the flour, it is gluten free. I am not a registered nutritionist or expert, this is just my basic understanding.

    Is chile relleno keto friendly? If you omit the flour, it is keto. I am not a registered nutritionist or expert, this is just my basic understanding. 

    What do I serve with chile relleno casserole? I like to serve a bright and colorful fruit salad, crispy home fries or even scones

    Is it a chilE relleno casserole or a chilI relleno casserole? Well… I used to ask myself the same question and then I asked a friend who was a book editor. 

    Her response was that anything that made reference to fruit of a chile was with an “e” while anything that referenced the soup or stew was spelled with an “i”. Since this recipe uses whole chile, it is a chile casserole. 

    Can I serve this casserole with salsa? Oh my goodness, YES! Salsa or any type of Latin tomato sauce (not an Italian marinara) will taste fabulous with this casserole. You can also check out my Green Tomatillo Salsa or even Chamoy Sauce.

    Can I add hash browns? I am sure you can, but I would make sure the are fully cooked before incorporating them into the egg batter.

    You might also need to increase the cooking time. If you do try this, come back and let us know how it went!
