My First Homemade Cook Book
Have I ever showed you guys my very first cook book? Long before our bestselling hardback, and before the days of easily-generated hardback photo books, and food blogs where you could store your favorites. This was back in the day where you formatted documents in Word, then printed them out one by one, sliced each page by hand, and took everything to your local Kinkos to copy and bind. Talk about labor of love! For Christmas one year I gathered all of my family’s favorite recipes. We are definitely a family bonded through food, and my Mother was notorious for her scraps and paper clippings organized in file folders and old cook books and lots and lots of post-its. I wanted to have them all in one place to pass on to my siblings who were all in pivotal life stages (one going off to college for the first time, one a newlywed, etc.) so we’d all have a little piece of home to take along with us.
The Best Kind of Treasure
This proved to be even more of a treasure as my Mom started getting sick around this time, and none of us could have predicted what would evolve in the years to come, as she lost the ability to cook, and all memories of these simple things that were such a big part of my family’s growing up years quickly faded away. I’m so happy I took the time back then to collect everything so we can all still have that part of her that we treasure so much.

I interspersed photos of everyone throughout the book, so it’s kind of like a food scrapbook. I noticed the other day, that while many of these recipes are now here on this blog, like my Mom’s Mint Brownies, or her beloved Peanut Butter and Jam Bars, and now that I have actual published cook books of my own, not to mention hundreds of other awesome cook books written by well known chefs, this book is still the one I turn to more than any other. For holidays, for inspiration, when I’m feeling in a cooking slump. It’s the book that takes me back to my roots and reminds me where I fell in love with cooking. It was at home.

I’ve been cooking and eating these Chile Cheese Souffle Squares since I was a little girl; it’s on tattered page 90 of this book, and you know which recipes are the most loved by how dirty the page is. This page is splattered in all sorts of things. It was one of my Mom’s go-to’s for and it’s become one of mine, too, and let me tell you why. My Mom called these “Appetizers” and would often cut them into little bite sized squares for parties, where for me, this falls into the breakfast casserole category.
Ingredients Needed
This is just a preview of ingredients and method, keep scrolling for full printable recipe.
- Butter – Use real butter.
- All-purpose flour – Gluten free flour works as well.

- Salt
- Eggs
- Fire-roasted green chiles – If you love chiles, you can add extra!
- Cottage cheese
- Monterey Jack cheese – Freshly grated. For an extra kick, feel free to use pepper Jack cheese.

How to Make Chili Cheese Souffle Squares Breakfast Casserole
- The first thing you’ll do is slice up your butter and place it in your pan, then pop your pan in the oven and turn it on to preheat. By the time you’re ready for the butter, it will be nice and melted.
- In the mean time, you’ll mix up the rest of the ingredients all in one bowl- this is seriously easy. It looks weird. I know. But something magical happens in the oven and what comes out is puffed, gloriously creamy, cheesy and flavorful.
- Bake, then let it sit for a few minutes. Cut into squares and serve.



Storing and Other Tips
- Store leftover souffle squares in an airtight container in the refrigerator and enjoy within 2-3 days for best results.
- Serving suggestions: These chile cheese squares are nice paired with another type of bread dish, like our Overnight Baked French Toast, or one of our many Sweet Roll recipes, but this one is just creamy and cheesy and it’s amazing what happens with such few ingredients.

Frequently Asked Questions
Yes. Cool completely and store, tightly covered, in the fridge and enjoy within 2-3 days for best results. Heat individual portions in the microwave at 15 second intervals (it will reheat quickly!) until hot.
The chiles really make this dish. If it’s a texture issue, you can blend the chiles with the eggs briefly before mixing everything together! If you really need to leave them out, it won’t affect the structure of the final product, just the flavor.

Chile Cheese Souffle Squares
Equipment
Ingredients
- 8 tablespoons butter 1 stick
- ½ cup flour
- 1 teaspoon baking powder
- dash of salt
- 10 eggs
- 7 ounce can fire roasted green chiles drained (if you love chiles, add more!)
- 1 pint cottage cheese 2 cups
- 1 pound monterey jack cheese shredded (don’t use pre-shredded, bagged cheese, shred your own.)
Instructions
- Slice butter into large chunks and place in a 9×13 pan. Place pan in oven and preheat to 400℉. (Keep an eye on this if you get delayed in the following steps so your butter doesn't burn!)
- Whisk together flour, baking powder and salt in a large mixing bowl. Add 1-2 eggs and whisk mixture until there are no lumps. Add in remaining eggs and whisk until smooth. Stir in green chiles, cottage cheese, and jack cheese and stir until just combined.
- Remove pan from oven and tilt pan so the butter coats all over then carefully pour butter into egg mixture and stir to combine. Pour mixture back into warm pan.
- When oven is preheated place pan in oven and cook for 15 minutes. Reduce heat to 350℉ and cook for an additional 35-40 minutes, or until top is golden and slightly browned. Let cool for 10 minutes before slicing into squares and serve.

Questions & Reviews
Just made this this morning for a breakfast gathering and had to comment. Someone had given me this recipie several years ago and I liked it ok… But on comparing the recipies I realized you cook yours much longer and the trick with the butter is amazing. Those two things put it over the top delicious. That yummy crust was what was missing! Funny thing is, the other gal who brought a casserole this morning brought the exact same one! Turns out she is an OBB reader too! Not a problem though because everybody raved! Thanks for resurrecting an old favorite.
Haha, I love it!
I know I’m super late (catching up on your blog) but I just wanted to say… YES!!!! This is basically my grandma’s egg brunch recipe (listed in the church cookbook by my mom as “Betty’s Egg Brunch”) except we do diced ham instead of chiles, and pretty much ONLY serve it at Easter. OMG, it’s one of my favorite foods ever! Now as an adult I add a little chopped spinach so I can pretend it’s less of a heart attack in a pan, and it’s even better. Once in college my roommates and I had a Good Friday brunch, and my roommate was SOOO grossed out when she saw the big bowl of raw eggs and cottage cheese, but when it came out of the oven it totally won her over! I made it for friends last summer at a lake weekend and everyone was wowed. So yes, I love this dish, and I love you for posting it, and I totally understand the “I know the cottage cheese seems weird but just trust me it tastes SOOOO MAGICAL” parts of this post. That is all. 🙂
hi there! i’m kind of in a pinch…do you think ricotta could be subbed for the cottage cheese in this recipe?? just wondering what your thought was. thanks!
Sorry, no idea. I only make it as written!
I made a half batch and subbed in gluten free flour. The entire family loved it!
My hubby is in love with the crust! He thought of maybe making this in a muffin pan to get more of a crust all around it. Have you tried this before and does it work well?
Yes, I have done that before! You just have to keep an eye on the baking time so they don’t dry out and get overcooked.
Could this be made the night before?
I have made a really similar thing slightly in advance (~4-5 hours before) and it worked fine… I’ve never tried it overnight though!
I feel like you mentioned it before but can you remind me where you bought that adorable polkadot baking dish? It is so cute!!
I have been making this recipe for over 30 years. You can substitute regular Bisquick OR Gluten Free Biscuick for the flour, baking powder and salt. Bake longer at higher altitudes. We always serve it with salsa on the side for those who like more heat.
I made this tonight — it was delicious! Thanks for all the great recipes!
I love that it can be made quickly, but is there any reason that it couldn’t be made the night before and baked in the morning? For holiday mornings, like Easter… I don’t want to do any prep, but I want a delicious brunch!
