Authentic Mexican Food

Growing up close to Mexico meant having authentic Mexican cooking in our home, as a way of life. It meant holding poblanos over the gas flame to char them, boiling nopalitos and mixing them with tomatoes, raw onion and cilantro, it meant albondigas soup. (It never meant an easy Keto, Paleo, GAPS Mexican dinner casserole, by the way; but we’re getting there!)

It meant chile rellenos on Friday nights.

Some were stuffed with meat, and some cheese. They were spicy and refined, silky and rich, surrounded by a bath of unadorned, smooth, hot tomato sauce. They were my dad’s favorite Mexican food. And they felt at once mysterious/other and like home.

Canned green chilies are one of the few prepared foods I still buy. For a busy mom that would NEVER at this stage in my life roast poblanos, their flavor brings me back to the comfort foods with which I grew up.

This casserole is spicy, by the way, so get mild chilies and mild salsa if you don’t want heat.

It has all the classic elements of an old favorite, but in casserole form — which means an easy assembly: it can be made ahead of time if that’s helpful, it has a quick kitchen clean-up, then pop it in the oven. I love casseroles! They’re down home, yet special.

Serve topped with sour cream, fresh cilantro and olives.

 

Keto, Low Carb, GAPS, Paleo, (egg-free) Mexican casserole~

It’s a Keto, Low Carb, GAPS, and Paleo Mexican casserole, yes! Such a lovely dinner for all these diets.

You’ll see the few variations below in the recipe, to make sure it’s right for you on the healing diet you’ve chosen!

One other detail to be aware of: The meat that goes into this casserole is raw. The meat cooks as the casserole bakes. A very light textured meat results because the casserole contains a bit of grain-free flour and leavening.

The raw meat also means one less step: This casserole is fast to make and assemble! The cooking happens in the oven. 🙂

  2. In medium size bowl combine salsa, tomato paste and cumin, stirring well. Measure out 1 cup. Set aside.
  3. Combine in small bowl: psyllium husk powder, baking soda and optional cream of tartar. Set aside.
  4. In large mixing bowl add the following: beef, water, the 1 cup portion of thickened salsa, onions, diced green chilies, apple cider vinegar, oregano, sea salt and pepper. Mix well.

  1. I am now a true fan! Not only does this casserole look amazzzing, but most importantly it is Keto! I can’t wait to make this for SuperBowl. I am sure it will be a huge hit .

    1. Aw, I love that idea!! Especially because it’s super good scooped up with pork rind chips and dipped in sour cream too! Such a fun SuperBowl meal or appetizer idea! 🙂 Thanks for your generous, kind words! 🙂

  2. Swoon! Oh how I would love to be at your dinner table. This looks absolutely delicious Megan. Such a special recipe.

  3. Drooling! I love how simple casseroles are too…just throw them in the oven and they somehow work out perfectly every time. This is such a unique idea and much more exciting than my usual casseroles!

    1. Thanks, Monique! So true, casseroles are the best. As the cook I LOVE getting the kitchen cleaned up once the dish is in the oven, *before dinner. 🙂

    1. I have a note there, to add as much or as little onion as meets your personal dietary goals. For folks on GAPS the onions are fine. You can entirely omit them for strict Keto, and the casserole is still great; they’re not needed. Thanks for the great question!

    Keto diet + Mexico Food…it cant get any better than that. I will be making this soon.

    1. Hi Lori, you can use the *coconut flour option* instead, if you prefer. See the recipe; it gives it as an alternative. 🙂 The powder or flour binds the casserole together and helps it to be light, because it gives it rise when it bakes. Don’t omit it entirely. 🙂

      Hi Jennifer, I think the casserole will freeze well, but I haven’t done it yet. Especially if you freeze it before baking, I think that will work fine. (Defrost overnight in fridge, then bake according to instructions.) After baking, again defrost overnight in the fridge and then on the counter for the last 4 hours, and then reheat in a low temp oven, like 300 degrees, covered until hot through to the center.

      Hi Shelley, yes, you can sub in almond flour. But I would go with the 2/3 cup measurement designated for the Paleo cassava flour option. (Coconut flour uses less because it functions differently in the recipe, not a 1:1 conversion to almond flour.)

  5. You said that you don’t freeze egg based casseroles but I don’t see any eggs in the list of ingredients. Did I miss something? Thanks!

      Hi Melissa, thanks for catching that! I updated my answer! 😉 I do think the casserole will freeze well. The casserole can be frozen either fully cooked and cooled or raw ready to bake. Wrap the casserole tightly to prevent freezer burn or contamination from raw meat. Whichever method you use, be sure to defrost the casserole thoroughly in the refrigerator before baking or reheating. A final 4 hours of defrosting on the counter at room temperature is safe according to food handling laws and may help the casserole to defrost through to the center more quickly.

      Not a dumb question at all. 🙂 Nope, the meat is raw going into the casserole which is partially why it turns out so light in texture when it bakes. And it’s one less step, which is part of why the casserole is so fast to assemble.
