Is This Casserole Low Carb or Keto?

The original version of this recipe had this as a keto cheesy low-carb taco casserole, with only 4 grams of carbs per serving. My analysis of my version of this recipe puts it as marginal keto with 5-10 grams of carbs per serving. If you use keto-friendly seasoning, it should count as keto.
