Who doesn’t like taco night?  That’s what I thought – everyone loves taco night! Here is a soon-to-be family favorite you’ll be asked to make again and again. However, this is not your typical, calorie-laden, carb-heavy taco casserole. Think of this casserole as more of a “lighter” but better version of those heavy in unhealthy carbs and overly rich in cheese and sour cream. This casserole steps up the nutritional power by adding in simple ingredients such as beans and veggies, creating a healthy meal. And did I mention how convenient this recipe is for those busy and rushed days? This one-dish meal provides the convenience of prepping it a day ahead of time. Think of how easy it will be after a long day at work and all you have to do is stick it in the oven to heat up.

This taco casserole is special – not only does it provide a mouthwatering and flavorful southwestern flair but with smart ingredient switches, it’s a healthier version you can feel good about. Whole-grain, corn tortillas take the place of chips or white flour tortillas. This simple swap provides more fiber, fewer calories and a much lower reduction in carbs. Adding canned black beans and tomatoes to taco-seasoned meat creates a nutrient-dense filling.  Top with a little bit of cheese, serve over a crisp bed of lettuce and use the Mexican yogurt dip – rich in calcium, phosphorus, potassium, and protein – for topping your casserole if desired or for dipping fresh veggies, and you’ve got a delicious, healthy meal ready to serve your family.

Is the Southwestern Taco dish low in purine? Watching my uric acid. This sounds so good.

Thanks in advance.

    Hi Penny! Thank you for a great question! The main food that might be a problem for you is the ground beef – while not considered a food high in purines, it is considered moderate in purines. What I would suggest as a good substitute for beef, would be ground turkey. The only other food that is also considered moderate in purines are beans. But beans are lower in purines than beef is. I would recommend using only half a can of the black beans just to be on the safe side.

    Thanks for reaching out, hope this information helps and enjoy the recipe and for following my blog!
