Instructions

Instructions are for 4 servings. Please modify as needed.

  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 Tex-Mex seasoning and crushed tomatoes. Stir and let simmer for 5 minutes. Taste to see if it 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 jalapeños and cheese.
  5. Bake on upper rack in oven for 15–20 minutes or until golden brown on top.
  6. Mix the scallion with the crème fraîche or sour cream in a separate bowl.
  7. Serve the casserole warm with a dollop of the crème fraîche or sour cream, guacamole and a green salad.

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.

    HI! a few modifications due to some lack of products in my area but the end product was great. I put a serving on top of cauliflower mash and it reminded me of shepherd's pie!! Thank you for sharing. This "stay at home" time has given me the opportunity to study, research and learn more about cooking keto. :)

    Made this last night, it was delicious, I made 2 portions for my husband and me, I just thought it was too salty for me. I will have to reduce the seasoning next time or won't add salt to the text-mex mixture.

    This is really good, I've made it many times. I wondered, however, can this meal be cooked in a cast iron pan on the stove, then into the oven for the cheese to melt?

    Yes, you could do this in a cast iron pan.

    I totally understand that it makes 4 servings as the recipe is written. However, what are the serving sizes? is 1 serving a cup, 150 grams, 300 grams etc.. of the finish cooked product?

    That is going to depend. If you use a leaner or fattier ground beef or how much the dish reduces in volume while it cooks. There are too many variables across different kitchens to give a serving size, especially for casseroles and soups.

    I'm not sure what you mean. This is a (green circle) keto recipe with 8g carbs per serving. Are you seeing it somewhere else with a yellow circle?

    Can tomato sauce replace crushed tomatoes?

    That might work, but it has not been tested and will adjust the carb count for the recipe.

    Since the recipe didn’t mention draining off the grease from the browned meat, I left it in the recipe but it was really oily when it came out of the oven. Should I drain off the fat before adding the spices and crushed tomatoes?

    That's truly personal preference. Some people prefer to drain, while others don't.
    If it was too oily for you, you may want to try draining next time.

    The guacamole is optional for this recipe, therefore not included in the nutritional information.
    However, here is a link to the guacamole recipe, which will show the carb count per serving. https://www.dietdoctor.com/recipes/low-carb-guacamole

    Family of four just devoured this! I ate with lettuce, diced onions, sour cream and guacamole. My husband, 8 and 5 year old ate it on low carb wraps. I made a separate dish for the kids and didn't put jalepeno's on theirs.

    It is a great day and a great meal when you can find something the entire family agrees on!

    This may be a not so smart question but i have to ask because i'm thoroughly confused for some reason. My question is related to the grams per Carb, Fat and Protein. Since this recipe makes 4 servings, do i divide the #'s provided in the nutrition section by 4 to get the individual carb, fat, and protein values per serving/per person.

    Can you explain how the net carbs add up to 8? Seems like it wouldn't be that high with the ingredients. Trying to understand what I am missing.

    The carbs in this recipe come from the Tex Mex seasoning (2g), tomatoes (3g), sour cream (2g) and the lettuce (1g).

    While tasty, mine looks nothing like yours. I used 85/15 ground beef & the whole thing ended up swimming in grease. The cheese & jalapenos sank into the ground beef, resulting in a much less appetizing appearance. Think I'll try ground turkey or a leaner ground beef next time. BTW, this is Day 1, Meal 2. I'm so excited about the possibility of breaking my carb addiction.

    Welcome Connie! For future recipes, you can use a leaner ground beef or drain it after browning the meat.
