02 -
  • Always check your taco seasoning for hidden sugars and carbs – or make your own with a simple blend of cumin, chili powder, garlic powder, onion powder, oregano, and paprika
  • If your casserole seems too watery after adding the tomatoes, simmer uncovered for a few extra minutes to reduce excess liquid
  • For the best cheese pull, use freshly shredded cheese rather than pre-packaged shredded cheese (which contains anti-caking agents)
  • Let the casserole rest for 5 minutes before serving to allow the flavors to settle and make it easier to portion
