Preheat the oven to 350°F.
In a large pot, bring the chicken broth to a boil.
Stir in the grits, seasonings, and butter.
Reduce the heat and simmer for 5 minutes, stirring occasionally, or until the grits have thickened.
Remove the pot from the heat and stir in the Velveeta, cream cheese, and sausage until the cheeses are completely melted and the mixture is well combined.
Stir in the Rotel and eggs until evenly incorporated.
Lightly grease a 9 x 13-inch casserole dish and pour the grits mixture into the prepared dish, spreading it evenly.
Bake for 40-45 minutes, or until the top is golden brown and the casserole is set.
Allow the casserole to rest for about 10 minutes before serving.
