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.

Family Cook Book

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.

Sara's Kid Pictures

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.

How to Make Chili Cheese Souffle Squares Breakfast Casserole

  1. 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.
  2. 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.
  3. Bake, then let it sit for a few minutes. Cut into squares and serve.

Frequently Asked Questions

Can I make this ahead of time?

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.

I have picky eaters, can I leave the chiles out?

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.

A creamy, fluffy egg dish using pantry ingredients. Perfect for a breakfast or brunch!
Prep Time 15 minutes
Cook Time 1 hour
Cooling Time 10 minutes
Total Time 1 hour 25 minutes
Servings12 servings

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.

Notes

  • For an extra kick, feel free to use pepper jack cheese!
  • 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.

Questions & Reviews

  1. I just came across this recipe and completely forgot that I’ve had it and made it several years ago! Have you ever made a smaller amount in a square pan? Just curious if you had the measurements for that.

    1. Yep (that’s actually what I’m doing for my photos here haha) Just cut everything in half and use the small 4oz can of green chilis!

  2. My mom made this every year and we always loved it. Do you think cooked sausage would work in this recipe?

  3. What a perfect recipe to post in December! Anything that can be breakfast can also be dinner in my book, and I’m sure I’m not the only one who needs more dinners that can be dumped and mixed in 5 minutes flat, and then a leisurely 45 minutes to make a big salad while it bakes. This was such a great, easy dinner tonight! For those wondering about reducing the fat content just a bit (maybe to put it in the regular rotation rather than only being a special occasion thing), I made it tonight with 5 tablespoons of butter and 1/2 pound of cheese. I increased the salt to compensate for using less of the salty cheese, and it worked perfectly. It was delicious!

    1. Cottage cheese is one of the main ingredients so I don’t really have a great substitution for that. I’m sorry!

  4. So, I made this and it is in the oven. I got sidetracked with the kids and browned my butter instead of just melting it. ? I am hoping it will still taste good. It seems like ALOT of butter to me. Is there any way to cut it down? I am really hoping this doesn’t come out greedy with the added cheese grease and then browning the butter.

    1. I don’t think anything is bad with browned butter, haha! They don’t turn out greasy, but if you’d like to cut down the butter, you’ll just need to experiment. Let us know how it turns out!

  5. Have you ever tried it with something other than cottage cheese? We live overseas and can’t find that here.

  6. 5 stars
    Made this during the holidays…….finally. It is so, so good. Thank you for sharing this family recipe!

  7. This sounds so good. Quick question….is it spicy? If so can you just use regular green chilies?

  8. 5 stars
    Oh my, make this for brunch on Mother’s Day, I could eat this every day of the week. My husband and my little dog loved it too 🙂

  9. I love the cookbook! I have been wanting to make one as christmas gifts for a long time. I never get started on time though. Where did you make yours? Its so cute!
