Easy Rice Casserole

Yeah, we all need shortcuts. I’ve shared a few doctored up cake mix recipes that come together quickly and always get rave reviews, like my Kahlua Cake and Lemon Bundt Cake. This Cream Cheese Tea Roll is a family favorite that starts with frozen bread dough. 

Though I tend to cook from scratch, when company is coming, an easy recipe like this cheesy spinach rice casserole is welcome.

How to Make this Spinach Rice Casserole

This easy rice casserole is pretty self-explanatory. But here are a few tips and reminders.

  • Remember to defrost your spinach a day ahead of time so you aren’t delayed when it’s time to mix up the ingredients.
  • Follow the directions of the box of rice to make that portion of the recipe. No need to let the rice cool before mixing.
  • I used Monterey Jack cheese in my version of this Cheesy Spinach Rice Casserole, but if you’d prefer Swiss or Cheddar, almost any other melty cheese would work well.
  • If you’d like, sprinkle some extra cheese on top during the last 10 minutes of baking for an extra cheesy topping!
  • The original recipe called for 2 boxes of spinach, but I only added one. If you’d like more veggies and less carbs per serving, feel free to add a second box.
  • PRO-Tip  –  Use a potato ricer to squeeze the liquid out of the defrosted spinach. Note that my resident dish washer hates to clean that. Another alternative is to use your hands to squeeze dry the spinach. I do this over a colander in case I drop some of the spinach.
