This Creamy Poblano Rice Casserole Recipe Will Leave You Speechless by Donna John

This Creamy Poblano Rice Casserole Recipe Will Leave You Speechless

No words. That's an overused statement, for sure, but it works for this creamy Mexican poblano rice recipe. What's creamier than creamy? That word might describe this recipe. Might. This creamy poblano rice casserole is one of my all-time favorite rice casserole side dishes. This easy, low-sodium poblano rice is a delicious way to add a bit of spice to dinner. It'll be a family favorite for sure.

The first thing to do is cook the rice and set it aside. Next, char the corn in a skillet and slice it off the cob. Roast the poblano peppers on a gas burner or in the oven under the broiler. It is so easy to do. Once they're black all over, remove the skin, ribs, seeds and chop.

The onion is cooked until soft, then the poblano and corn are stirred in along with the garlic. Add fresh cilantro, sour cream, shredded cheese and heavy whipping cream. (Don't forget to put the rice in, too!). Stir it all up and bake until hot and bubbly. Amazing!

The flavors in this gluten-free rice side dish are incredible. Serve this cheesy Mexican rice casserole as a side dish with chicken, pork, beef, seafood or whatever you enjoy for dinner!

This rice recipe is SO delicious. I cannot stop thinking about it now. Trying not to grab my keys and run to the store for the ingredients.... :-)
Looks good I'm going to try it can you add anything to it or will it mess up the recipe any meat or poultry or fish that you know corresponds with the rice let me know if you have any tips thank you
Donna John
I make this recipe as is. I've never added chicken, but how could that be bad?? Not sure about fish. Rosseyes
It was delicious! I did mix it up a bit-I hate changing recipes for first time but I didn’t have white cheddar so I used smoked Gouda & didn’t have cilantro so added lime zest & juice for freshness. Threw in a little cumin to play off the Gouda. I didn’t have fresh corn so I used a bag of steamed and then cooked it alone in a super hot pan alone to char it. It turned out amazing
Donna John
So happy you enjoyed it!! It's one of my favorites. Love the idea of using smoked gouda! Sarahd
