4 servingservings


  • 25 oz. 700 g ground beef
  • 7 oz. 200 g crushed tomatoes
  • 2 oz. 50 g pickled jalapeños
  • 7 oz. 200 g shredded cheese, for example Monterey Jack
  • 1 cup 240 ml crème fraîche or sour cream
  • 1 1 scallion, finely choppedscallions, finely chopped
  • 2 oz. 50 g butter
  • 1 cup 225 ml guacamole, for serving (optional)
  • 4 oz. 110 g leafy greens, for serving
Make your own Taco seasoning
  • 2 tsp 2 tsp chili powder
  • 2 tsp 2 tsp paprika powder
  • 1 tsp 1 tsp ground cumin
  • 1 - 2 tsp 1 - 2 tsp onion powder or garlic powder
  • 1 pinch 1 pinch cayenne pepper
  • 1 tsp 1 tsp salt (optional)


  1. Preheat the oven to 400°F (200°C).
  2. Fry the ground beef in butter on medium high heat, until cooked through and no longer pink.
  3. Add taco seasoning and tomatoes. Stir and let simmer for 5 minutes. Taste to see if if needs additional salt and pepper.
  4. Place the ground-beef mixture in a greased baking dish (about 9" or 23 cm in diameter). Top with jalapenos and cheese.
  5. Bake on upper rack in oven for 15–20 minutes or until golden brown on top.
  6. Chop the scallion finely and mix in with the crème fraiche or sour cream.
  7. Serve the casserole with a dollop of crème fraiche or sour cream, guacamole and a green salad.


Don’t be intimidated! Making your own 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 do no wrong!

This casserole can be frozen. Let thaw in the refrigerator a day before you plan on serving it. Don’t place a cold baking dish straight from the fridge into a hot oven, as this can cause your dish to crack. Reheat the casserole in the oven at 300°F (150°C) until thoroughly warm.

    I'm not sure what I'm doing wrong, but MFP is showing 12 net carbs for this meal. Can anyone explain what I'm doing wrong?

    This was very good. I altered it slightly and added some black olives on top. There isn't any specific measurement for the Tex Mex Seasoning... I used 3 tablespoons. Also, I used half the cheese. When I served it, I added sour cream and chopped avocado. Husband was particularly pleased.
  3. Brad
    I made 8 servings. Simple and good. I used raw jalapeños, seeds and all but sauteed a little first. I wish the recipes listed calories and grams of fat and protein. i don't really want to type all this into MFP to get the nutritional information.

    Amazing!!! Our family loved this one.

    In the UK, we call "ground beef" simply "mince" or "minced beef". Surprised the US is still on imperial units - the rest of the world metricated 40 years ago ;-) Glad to see there is a button to click on to get metric units though :-) What is a scallion? It appears to be a spring onion. It is interesting to see the different names for things around the world. :-)

    Another winner, another favorite for me, and family loved it too. I didn't do too much different. The seasoning mix was great, much better than a purchased packet with all sorts of gunk in it, including gluten sometimes. I cooked the 80/20 beef without butter as it has plenty of fat in it for cooking. I didn't end up having to drain off anything, either. I added some chopped onion, and when finished I also threw in a few slices black olives. I used a Mexican jalapeño mix grated cheese and that was good. The crème fraiche is sour cream if you haven't figured it out. That should be corrected in the ingredient list, although it is correctly referenced in the instructions. I put a lot of little sliced scallions into the sour cream, and in the guacamole I put some red pepper and some tiny chunks of onion, lemon juice, and mayo. Both the sour cream and the guacamole were nice with the casserole. I did 3 serving size and used almost all of a 15oz can of petite tomatoes (not crushed) and some but not all of the juice in the can. I cooked the meat with tomatoes for awhile to reduce the liquid a bit, but it didn't really get too watery, and was fine when the casserole was heated. We didn't even miss the usual tortillas it all tasted so yummy. This one goes on my recipe rotation!

    its gotta be on the side, not for sure tho.

    Made it as directed and it was delicious!! I've made this a few times and I think it can be customized easily with stuff like olives, bacon, etc. My family is not LCHF and they eat it with tortilla chips and soft corn tortillas. I eat it on a bed of lettuce with avocado, onions, and sour cream. Thanks again for a great, quick, and easy recipe!

    very tasty, thank you! made 8 servings. used 2/3 ground pork and 1/3 ground beef as that is what we had on hand. added a small can of green chilis, but only used 2 oz of jalapenos. used the full amount of taco seasoning even though it seemed a bit much when looking at it. also reduced the butter to 2 oz and added 1 T olive oil. served over chopped romaine without any additions

    Hi T&H!

    It should work ( test again) .

    Cannot edit the serving count?

    How many calories are there? They aren't listed in the nutrition.
  17. Vicky
    Lorraine, Creme freche and sour cream are very similar (but not quite the same), so creme freche in the ingredients is the sour cream in the instructions - just a mix up of terms..
  18. Vicky
    Hi Brian, scallion can indeed be a 'spring onion' but it is sometimes means a 'shallot' - a small onion the size of a pickled onion but slightly 'sweeter' in flavour. The spring onion has less carbs because of its green leafy top. As you say - different names for different places!
  19. Vicky
    Brian - just noticed - scallion is in the list of ingredients and described as chives in the instructions - as its in the creme freche/sour cream, then chives would be best!

    I noticed a lot of people asking about the macro counts, so I calculated it in an app. I used chicken thigh meat in the calculation. I used the ingredient list to serve 4 and came up with this per serving: 590 cal, 54 protein, 40 fat, 1fiber & 7 carbs. Happy eating!
  21. JustStartingKeto
    Forgot to tell you that my calculation was EXCLUDING avocado. BTW, I’ve made it since posting the calculations. Although very tasty, the serving size it’s not a substantial meal. For those macros, if you’re after weight loss, you might want to eat a smaller portion on a day you have extra carbs available and pair it with a good sized salad or vegetable serving.

    where does the crème freche get added?

    That's what I'm wondering. There's also sour cream in the method but not the ingredients so maybe there was a mix up.

  23. Louise Jenkins
    I was wondering too
  24. sarah
    I didn't love it. Maybe its because i used fresh tomatoes and smashed them instead of canned ones? I wouldn't make it again. Not anything special, but not bad either.
  25. Greg
    I wish we would hurry up and go metric. Makes a lot more sense! And yes, scallion = spring onion...
  26. Melissa
    One of our all-time favorites!!! YUM!

    Odd question but do you drain the grease from the hamburger when it's browned? Asking for a friend.

    You know what works great for casseroles? Freezing them in the dish, then popping them out and putting the casserole-ice-cube in a bag. I vacuum seal mine. I put a label saying which dish I used to make it, and then I defrost it in the dish. Works great!

    I wish they would state the serving size. I made this according to 4 servings and guessed it was a cup serving...doing it that way probably makes it 5 servings. It is definitely filling. I omit the hot peppers and add green peppers and regular onion. I also do diced tomatoes. Makes it more of a chili than a casserole, but I like it.

    Wow, this was so good! A bit too spicy for my taste but that's something I can adjust to my own taste. Love the combination of spicy, sour, cheese and soft guacemole. I ate it with iceberg lettuce as tacos. Yummm. This is a keeper on my list.
  34. Chad
    This was great, I dont have the right oven dish though so I mixed everything in a small pot and left it on the lowest heat on the hob. until it thickened.
    Worked great. Will try again.
  35. Danny
    Can I use ground turkey in this dish .
  36. Gordon
    Absolutely delicious.
