Make your own Tex-mex seasoning

Don't be scared to recreate the flavors of Texas and Mexico right in the comfort of your own kitchen. Making your own Tex-Mex seasoning blend kicks sugar out the door and puts you in the driver’s seat. And, since variety is the spice of life, play around a little! Switch in hot smoked paprika or smoked salt. Grind up dried specialty peppers, or chop up a chipotle in adobo sauce. Taste as you go and you can't go wrong! Your Tex-Mex experience will be elevated to the next level.

How to vary this dish

This casserole can be varied in a million and one ways. You can wrap it up in our low-carb tortillas, fill a crunchy keto taco shell or serve it burrito style. The whole neighborhood will want to spend Taco Tuesdays at your place.

If you're not so much into the southern spice mood, substitute the Tex-Mex flavors (seasoning, jalapeños and guacamole) for pesto or add garlic powder, basil, salt and black pepper to taste. Top it with shredded mozzarella, sliced fresh tomatoes and a generous amount of grated parmesan cheese and you'll have an Italian version that's to die for.

If you feel like flirting with Indian cuisine you can substitute the ground beef for ground pork or ground chicken and season it with curry powder and Garam masala.

How to store this casserole

This dish can be stored in the refrigerator for 3-4 days or in the freezer for up to 3 months. Let thaw in the refrigerator a day before you plan on serving it. Remove from the fridge about 30 minutes before reheating. Placing a cold baking dish straight from the fridge into a hot oven can cause your casserole dish to crack. Reheat in the oven at 300°F (150°C) until thoroughly warm.

    This recipe ills hunger in its track! Woo hooo! I decided to try intermittent fasting after eating this deliscious meal. I had it for early dinner 4pm. What really stunned me was that by 11pm I wasn’t hungry. I broke my fast 10:30am the following day. Will continue to make this dish, my husband who is not on the keto diet also loves it! I mad the spice mix and guacamole according to all the instructions. Since like was listed that what I used in my Tex mex prep. Thank you!

    Hands down one of the best keto recipes here. I used taco seasoning instead of tex mex and it turned out just amazing with rich flavor.

    I was doing well on keto until I ventured onto Pinterest, all Keto recipes aren't good keto recipes. Well, I'm back and I made this! I added black olives and extra jalapenos and it is delish! The only thing I would change is using a leaner meat. I made this with 80/20 Angus ground beef and there was a lot of oil...still delicious though.

    Mince and ground aren't exactly the same thing. Mince is more finely done, so I would guess it's processed differently. Then there's mincemeat, which is not just meat at all.

    Cooking in butter adds flavor. Even to just plain meat.

    My husband and I both loved this. Frying 80/20 beef in even half the amount of butter still produced too much grease, so will either leave out the butter next time or will buy leaner beef. The Tex-Mex spice blend is what really made the dish delicious. I added smoked paprika and the smell while it was cooking was out of this world. I will definitely be making this again! I'm looking forward to using it for my taco salad!

    Thanks for the old recipe for Tex Mex Hans,
    I’ve never tried the original one but I found this one a bit salty

    I would suggest adding "drain meat mixture" after cooking the hamburger. I consider that step a given but some folks need the instruction. There is a thing as too much "fat" especially since the fat off hamburger is "bad" fat. Also, budgeting restrictions do not always allow for the pricey extra lean ground meat. All of the recipes I have tried here have been delicious but none of the ones I have seen say anything about draining.

    Delicious . I used sliced fresh tomatoes and fresh green chillies instead of pickled jalapeños. I also steered in tomato paste and red pesto. Very hot, delicious and filling.
  13. Julie
    Delicious! I made it with turkey mince so no excess oil. Also used smoked paprika in spice mix. So rich and filling - love it.

    you have a typo on your item #3 "Add Tex-Mex seasoning and crushed tomatoes. Stir and let simmer for 5 minutes. Taste to see "if if" needs additional salt and pepper. Should be if it, not if if. Thought I would let you know so you can fix.

    Thank you! We will get that corrected.

    Is it okay to substitute ground turkey for the beef? I've been eating the turkeyburger so long that I don't care for the taste of ground beef! I love a good steak, though :)
    Thanks

    Thanks

    Yes, just a heads up that ground turkey is lower fat and higher protein.

    One of the best Tex-Mex recipes I've made, when you wrap it up in a low carb whole wheat tortilla, it tastes like a Meximelt from Taco Bell.
  20. Linda
    Excellent recipe! A new favourite! The spice mixture is perfect!

    Could I eat this one time a day or 2 and just have that as my meal everyday or is that not how a keto diet works

    You could if you wanted to, but there are so many amazing keto recipes out there, there is no need to limit yourself to just 1.

    I make bone broth once a week and use the use the discarded meat in this mix and is delicious!!
  24. Geoffrey
    Fantastic meal - was slightly spicy so I’ll reduce the chilli in the tex mex seasoning next time. I had with a side salad and used in a burrito for my family. Will definitely be on the regular recipe list

    Does the carb count include the optional items such as creme fraiche, guacamole, and lettuce, or just the main ingredients? Thank you

    They include all of the ingredients in the For Serving except for the guacamole which is listed as being optional.

    I made this today. It is FANTASTIC!! I used fresh jalapeños instead of canned/pickled. Honestly, it is absolutely delicious. Thank you for recipes ❤️💕😘

    This was so good. Easy to prepare and delicious.

    Made this tonight. Agree with others that it was greasy. I took the recipe literally and used 80/20 beef in the butter without draining meat fat. I'm new to Keto and the higher fat intake. Many commented here that they omitted the butter entirely. Wouldn't that change the macro counts for the recipe? I think the next time I try this I will use very lean beef, browning it first. There will not be any grease left over so I'll add in the butter for flavor and the "good" kind of fat. I followed the rest of the recipe as listed and it tasted really good. Big bed of lettuce on the bottom with a serving of the casserole topped with 'sour cream'. Tasted just like a Taco Salad without the chips...

    Yes, omitting the butter would affect the fat count. As far as draining the meat, that's totally personal preference. Some people use leaner ground beef and there's no excess grease to drain.

    We made this meal tonight. My sister is keto, my husband, our mom and I are not. We all LOVED it. We used a 14-oz can of tomatoes because it looked dry, and pepper jack cheese, and I just seasoned it with cumin, chili powder and garlic (quantities unknown). Definitely a keeper!

    This was great. I added a little chipotle past that I had left over from another recipe. Give it more of a kick.
