How to Lower the Carbs in Keto Taco Casserole
This recipe is a little higher in carbs than most keto recipes I create (10g net carbs per serving). If you need to lower the carbs a bit, here are a few ideas:
Increase the number of servings. This recipe is made with 6 servings that are quite hearty. If you don’t need quite such a hearty portion, increase the servings to 8 servings (7.5g net carbs each), 10 (6g net carbs each), or even 12 (5g net carbs each).
Remove the red onion. Although I love the added flavor of the red onion, if you can do without it, doing so will reduce the net carbs per serving to 8g each.
Intermittent fast. This makes a great and hearty first meal of the day if you’re intermittent fasting! I know this doesn’t actually lower the carbs in the recipe, but it’s more acceptable to consume higher-carb recipes like this one if you’re eating fewer meals.
Can I Eat Taco Casserole on the Keto Diet?
You can eat taco casserole on the keto diet by removing heavy net carb ingredients and substituting them with low carb ingredients. You must avoid using beans, corn tortilla chips, corn, and any other high carb ingredient. These high carb ingredients will knock you out of ketosis. Also, they don’t qualify as low carb either.
How Do I Make Taco Casserole Keto-Friendly?
You can make taco casserole keto-friendly by avoiding high carb ingredients like corn, tortilla chips and beans and substituting them with low carb ingredients like red peppers and extra cheese.
