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.

    Great recipe. Thank you!

    I'm going to try this, or something very similar, tonight. I often use bolognes or chilli type sauces with seasonal veggies (runner beans, asparagus, purple sprouting broccoli, courgettes/zucchini, vegetable marrow, aubergine etc.) substituting for the starches. This looks like another useful variant.

    Going to try this. Looks very good.

    Onion isn't listed in the ingredients. Green onion or chives goes in the sour cream but how much onion goes in with the beef?

    Recipe does not mention onion in the recipe at all......so none for this version!
  6. Mary Lynn
    We make homemade salsa from our garden (sugar free) and use that instead of tomatoes peppers & all the spices. I didn't think that would change the carb count much, any advice on whether we really messing it up?
  7. Sue
    Ok here is a question... It says half can of tomatoes but didn't say what size can? Be useful to know as the can in our pantry is 28 oz

    I had this last night and leftovers today and it is definitely going to become a staple in my weekly menu, it's absolutely gorgeous!
  10. Linda
    We layered the dish with poblano chilies (charred with the skins and most of the seeds removed.) We used shredded Oaxaca cheese, chipotle chile and smoky paprika because they were both in my pantry. Will continue to make this!
  11. Anne
    Fabulous! Whole family loved it. Thank you!
  12. Dirk Van Giel
    Due to geographical reasons some ingredients may differ from the ones mentioned in the recipe. In some countries there is no such thing as Monterey Jack or Oaxaca cheese and pickled jalapeños or poblano chilies are very difficult to find. One needs to be creative and replace them with whatever is available and in any quantity you seem right. I for instance use entire garlic cloves as substitute for potatoes... when cooked they get soft and mild. Delicious in all my LCHF-recipies.
  13. Jan
    What size can of tomatoes did you use? The only size I could find was the 28oz can. Suppose I will half that one unless I hear otherwise.
    Also chuckled at the "Soured" cream. I guess that is what it really is but I have never seen a container that calls it that. Around here, in Texas, and I think the rest of the US it is Sour Cream!
  14. Angela
    Just tried the recipe and it was delicious. Will definitely make it again. I didn't have minced beef so used minced lamb instead .... a winner with the whole family

    I was wondering about the size of the crushed tomatoes as well, plus the original shopping list did not include multiple bunches of scallions/green onions. Since my area is in the middle of an ice storm, I'm going to use what I have in the pantry, freeze-dried chives.

    MonaLisa, where are you located? As Jan said, in the U.S. it's called sour cream. I think I'd run from it if it said 'soured' cream! ;-)

    BTW, this is Day 5 for me and I haven't lost an ounce! No cheating, stayed under 20 g carbs, drinking a lot of water. What am I doing wrong, and does anyone have any suggestions?

  16. Sue
    Anita, not sure if you are doing anything wrong... but one suggestion that I might make is to try to have bullet proof coffee and skip breakfast. 2 tble spoons coconut oil in coffee... I blend it in with a stick blender... and it seems to help me with intermittent fast and I started to see a bit of loss. Just came back from vacation in mexico... and it was a bit tricky to stay with diet at AI resort... so I am starting again... and the coffee and intermittent fasting is the first thing on my program. Good luck to you

    Not sure why there is no response to the size of tomato can??? Maybe the doctor doesn't monitor these comments?

    In Canada, it's called "sour cream" ;)

    Hi,
    Just wondering when frying the hamburger you say to cook it in butter. I was told you have to drain the fat after frying hamburger . I'm in Canada and you can get regular, lean and extra lean hamburger. I have always drained the fat off the hamburger am i missing something? Should I drain the fat then add he butter or just cook it adding butter? Wouldn't the end product be too greasy and taste bad?

    I made this last night it's delicious. The only thing I did differently is I added Cauliflower to it, it worked really well.
  20. Sunny
    I am 61 years old, MonaLisa, and live in the USA. I have never seen it in any store in the states I have been in here that sells it as Soured Cream. Every brand here is always called sour cream. I guess if you make it yourself you can call it that but most people buy it from the store here.

    You were saying that you haven't lost any kgs..... but don't worry about the kgs. You must measure your whole body and you will find you are losing the cms more than kgs.
    Good luck to you, Anita...
    I am from South Africa and here in SA .... we do have sour cream. Other day I ran out of cauliflower and I ate rice .... well I must say that I was so sick and couldn't eat the rice.
    Hi All
    Tried something different and you will love it. Fried the chicken in coconut oil, then add the mushrooms and bacon then add the cabbage in and fried these all together in pink salt. Then add the cup of fresh cream till the cream is already there. serve right away....

    Sour Cream in Australia :)
  23. Sue G.
    Has anyone noticed that there are very few vegetables in all of the dishes? I really miss having a salad.
  24. Connie - South Carolina
    Sue it says serve with a salad, sour cream & guacamole
  25. Maila
    We had this tonight. It was delicious! I skipped the tinned tomatoes as I didn't want the mince to go too "wet" and kept it quite mild as I've got two young boys. I served it with fresh salsa (used the recipe from Sunday's dinner), home made cheese nachos (melted cheese), and sour (soured if you're British) cream. I think this will become a family favourite !!
  26. Jamie
    It's sour cream in the United States too!! :)

    Mona Lisa,

    In the US it is sour cream.

  37. Popi from Canada
    No news on the size of the can of tomatoes?
  38. Liz
    I'm making this tonight and I've already tasted it. Delicious! For those of you wondering about the amount of crushed tomatoes, it's 2/3 cup, which is about 1/2 of a 15 1/2 oz can. This came together super fast and I was wondering if it would be really spicy. It's not. Great flavor! Can only imagine it will be even better once I let the cheese melt! I love the recipes in this challenge. They have all been delicious.
  39. Cindy
    This one is a keeper. I will be making it often. I used extra sharp cheddar cheese and fresh jalapeños
  40. Dylan
    Hey guys going To try this tonight and what I've always noticed when cooking is when it says 'can of tomatoes' it is usually the 400g tin (Australia) which is the most common size, plus if you look at the amount of mince it requires, you have to think reasonably, a tiny tin wouldn't be enough and a massive tin would be too much, I could be wrong, but it's just what I've noticed previously.
  41. Mayra
    Realmente riquísimo
  42. sunanda
    i enjoyed this dish pretty much..
  43. Lucille
    I made this for a family gathering and they nearly licked their plates it was so good. I didn't change a thing in the original recipe. The can size for crushed tomatoes is 28 ounces here in the States. I ended up measuring it out as about 14 ounces.

    Serving it again tonight for birthday celebration dinner along with guacamole, sour cream with chives and a beautiful green salad with a vinaigrette dressing. There will be a low-carb birthday cake and lchf home made ice cream. ` special occasion splurge meal I am lucky that our extended family are all following lchf lifestyle so I don't have to cook two different meals.

    I was surprised at how many carbs an onion has. Before I really settled on a LCHF diet, I was trying to combine concepts from books I'd recently purchased: Eat Fat, Get Thin; The Microbiome Diet; Atkins, which I had lost nearly 100 pounds with in my youth...anyway, I was frying up a chopped onion as a bed for my eggs in the morning. I was kind of stalling out in the weight loss department, so I figured I better check the things I'd been assuming were low carb. One medium onion has 14 carbs, 3 fiber for a net of 11 usable carbs. (I had been using the large, sweet ones you get at Costco.) When I realized that this was more than half my day's allotment, I stopped using onions so liberally! I've found it very helpful to keep a carb counter book handy. In the back of it, I have a little chart for the ingredients I use frequently. Hope this helps.

    I know you're supposed to eat lots of fat with this diet; that's what fills you up, so I have a question about the sour cream...and not whether or not it's called such...has anyone just stirred it into the mixture before serving, or is it better to leave it as an add-on? I'm not a huge fan of Mexican food or of fat, but I am amazed at how quickly I get full when I eat fat. I would not use it if it were "on the side," but I wouldn't be against just stirring it in. Please advise!
    I'm behind on my menus, because the chicken dish lasted for three dinners and three lunches. I used my second container of sour cream in some flax meal-coconut "pancakes" (I cooked up ten of them so I won't have to cook breakfast for a while!) so would need to get some more. That's okay. Tonight will be pizza! When I do get around to making this, do you put all of the taco seasoning in?!
  46. Julie
    Just had this for dinner, with the homemade guacamole and everyone loved it! Even my picky 10 yr old. Will definitely make again! thx!

    Hello,
    I love your emails and recipes!
    However, I am not finding out the carbs amounts for these recipes...where should I look?

    Kind Regards,

    Oh my goodness - totally delicious with the guacamole. I was amazed to find the pickled jalapeno in the Uk, and I used garlic granules instead of powder. And i can confirm that it is "soured" cream in the UK . ☺

    I made this but my ground beef was very greasy i did not drain but felt i should have so now i am thinking it did add to the flavor was very tasty will be making this again.i used tomatoes with green chilis and no sour cream .
