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. 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. 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.
