Slow Cooker Rice Casserole with Green Chiles and Cheese

This Slow Cooker Rice Casserole with Green Chiles and Cheese was made in the Crock-Pot Casserole Crock, but use a large oval slow cooker if that’s what you have! You’ll love this ultra-tasty cheesy rice that starts with cooked rice and only takes a few hours in the slow cooker.

If you’re someone who’s following a carb-conscious eating plan then this Slow Cooker Rice Casserole with Green Chiles and Cheese will definitely be a splurge on carbs. But I made this with low-glycemic rice combined with other healthy low-carb ingredients and if I was making one of my Low-Carb Mexican Food Dinners, I might make this as a side dish for other people (and maybe eat a small serving myself if I needed a treat!)

The recipe uses pre-cooked Uncle Ben’s Converted Rice (affiliate link), and many sources claim parboiled white rice is healthier than other types of white rice. Don’t use the *instant* versions of Uncle Ben’s, which are much higher in carbs and higher on the glycemic index. If you do decide to splurge, I hope you enjoy this slightly-spicy and cheesy rice casserole. It’s been a hit with everyone who’s tried it in my huge extended family!

What if you don’t have the Casserole Crock Slow Cooker?

I do love the Crock-Pot Casserole Crock Slow Cooker for dishes like this, but any kind of large oval slow cooker (affiliate link) will definitely work!

How to make this recipe:

(Scroll down for complete recipe with nutritional information.)

  1. Start with 5 cups cooked Uncle Ben’s Converted Rice (affiliate link). Thinly slice 2 cups of sliced green onions and mix them into the rice.
  2. In a bowl or large measuring cup, mix together the sour cream, 2 cans diced green chiles with juice, Green Tabasco Sauce (affiliate link), and grated Mozzarella.
  3. Combine the sour cream mixture with the rice, and season to taste with salt and coarse ground black pepper. (I didn’t use much salt and pepper.)
  4. Put the mixture into the Crock-Pot Casserole Crock Slow Cooker (affiliate link) or any oval 3-4 quart slow cooker that you’ve sprayed with non-stick spray or olive oil, then top with a little more grated Mozzarella and a few tablespoons of Parmesan cheese.
  5. Cook on high for about 2 hours, or until it’s bubbling hot, cheese is melted, and it’s starting to get browned on the edges. (You could probably cook this on low for a longer time, but I haven’t tried that.)
  6. One thing I love about the Crock-Pot Casserole Crock is that when the food is cooked through in the slow cooker, you can put it in a hot oven for a few minutes to brown the top, and I did stick this in a hot oven for about 15 minutes, but that step is completely optional. (I wouldn’t try that with another type of slow cooker unless you’re sure the manufacturer says it’s okay.
  7. Serve hot and enjoy with your favorite Low-Carb Mexican Food!

Slow Cooker Rice Casserole with Green Chiles and Cheese

Yield 8 servings
Prep Time 25 minutes
Cook Time 2 hours
Total Time 2 hours 25 minutes

I used the new Crock-Pot Casserole Crock Slow Cooker for this Spicy Slow Cooker Rice Casserole with Green Chiles, Green Onions, and Cheese. but you can make it in a large oval slow cooker as well.


  • 5 cups cooked long-grain white rice (see notes)
  • 2 cups thinly sliced green onions
  • 1 cup sour cream
  • two 4 oz. cans diced green chiles (see notes)
  • 2 T  Green Tabasco Sauce, to taste (see notes)
  • 1 1/2 cups + 1/4 cup grated Mozzarella cheese
  • 2 T finely grated Parmesan cheese


  1. Mix together cooked rice and sliced green onions in a bowl that will hold all the ingredients.
  2. In a separate bowl or large measuring cup, combine the sour cream, diced green chiles and juice, Green Tabasco Sauce, and 1 1/2 cups grated low-fat mozzarella cheese.
  3. Mix the sour cream mixture into the rice mixture and gently combine.
  4. Spray the Casserole Crock or a 3-4 quart oval slow cooker with non-stick spray or olive oil.
  5. Add the combined rice mixture and press down so it’s evenly distributed in the slow cooker.
  6. Sprinkle the top with the rest of the grated Mozzarella cheese and the Parmesan cheese.
  7. Cook on high for 2 hours, or until the rice is bubbling hot, cheese is melted, and it’s starting to brown around the edges.  (You can probably cook this for a longer time on low, but I haven’t tried it.)
  8. If you're using the Casserole Crock you can put it in a hot oven for a few minute to brown the top. I don't recommend doing that in other slow cookers unless the manufacturer okays it.
  9. This rice will keep well in the fridge for several days and can be reheated in the microwave or in a covered dish in an oven or toaster oven.


I used a Crock-Pot Casserole Crock Slow Cooker (affiliate link) to make this recipe, but any large oval slow cooker (affiliate link) will work.No need to drain the cans of green chiles for this recipe. Use diced green Anaheim chiles, no Jalapenos! Read here for more about Green Tabasco Sauce, my favorite hot sauce. Use Uncle Ben's Converted Rice (affiliate link) for low-glycemic diets or the original South Beach Diet.

Recipe adapted from Cheesy Chile Rice from Food Network Magazine Great Easy Meals.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
If you’re making this Spicy Slow Cooker Rice Casserole for the original South Beach Diet or another low-glycemic diet, it’s important to use low-glycemic Uncle Ben’s Converted Rice or brown rice, and South Beach would recommend reduced fat sour cream and reduced fat Mozzarella cheese.  With those ingredients, this rice would be a great side dish for Phase 2 or 3 of the South Beach Diet as long as you limit portion size. This is relatively high in carbs for traditional low-carb diet plans, but check the nutritional information to see if it’s too much of a splurge for you.

  1. It's such a great feature to be able to brown in the oven after cooking in the new casserole crock. Can't wait to try it!

  2. What a neat idea! This looks delicious. Pinning!

  3. Thank you for clarifying Kalyn. I'm making it as we speak.

  4. Eyelady, the directions should say cook on HIGH for 1-2 hours. So sorry; drives me crazy when I do mistakes like that. Thanks for telling me and it is now fixed!
