For this week’s Friday Favorites post, I’m reminding you about these tasty Southwestern Cauliflower Rice Stuffed Peppers that are a delicious version of stuffed peppers that uses cauliflower rice! I absolutely love the idea of stuffed peppers that substitute low-carb grated cauliflower for the rice that can make stuffed peppers high in carbs. 

Be sure not to skip the addition of finely chopped Poblano Chile Peppers (also called Pasilla peppers in many U.S. stores.) The Poblanos are barely spicy, and they add a wonderful flavor to the cauliflower rice stuffed peppers. I used red, yellow, and orange bell peppers for a colorful dish, but green bell peppers would also be delicious for this.

I created this recipe with help from my niece Kara, and we thought the cauliflower rice was delicious with the other flavors here. And even for people who aren’t big of fans of cauliflower might enjoy these stuffed peppers where there are so many good flavors to season the cauliflower; enjoy!

What gives the Cauliflower Rice Stuffed Peppers Southwestern flavors?

Poblano peppers added to the filling and Kalyn’s Taco Seasoning plus ingredients like onion, peppers, and grated cheese all give these stuffed peppers lots of Southwestern flavor!

Can you use frozen cauliflower rice for cauliflower rice stuffed peppers?

I haven’t tried making peppers like this with frozen cauliflower rice, but I think that would work just fine if you let the frozen cauliflower rice thaw before you use it and cook the onion/pepper/cauliflower rice mixture at high enough heat to evaporate some of the moisture.

What are Poblano Chile Peppers?

Poblano chile peppers are large dark green peppers that are mild but have a really delicious flavor. In U.S. grocery stores they are sometimes called Pasilla Peppers.

How to Make Southwestern Cauliflower Rice Stuffed Peppers:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

  1. Heat olive oil and cook the ground turkey until it’s nicely browned. Don’t rush this; it might take 10-12 minutes to get the turkey as brown as this. (Remove turkey and set aside or use a different pan to cook the onions and peppers.)
  2. While the turkey browns, cut stem end off the peppers. Then carefully slice off the other end, removing just enough to make a flat surface so the peppers stand up. Put peppers in a baking dish.
  3. Cut the cauliflower into small pieces and buzz in the Food Processor (affiliate link) just until pieces are about the size of grains of rice.
  4. (I haven’t tried making this with frozen cauliflower rice yet, but I think it would work if you prefer that. I would thaw the frozen cauliflower rice before you use it in the recipe.)
  5. Chop the Poblanos, pepper ends, and the onion.
  6. Brown chopped onion with some taco seasoning, then add the peppers and cook a couple minutes more.
  7. Add the cauliflower to the pepper/onion mixture and cook about 5 minutes. Then mix in the browned turkey.
  8. Let the mixture cool for a minute or two, then mix in the grated cheese.
  9. Use a spoon to fill each pepper with the onion/pepper/turkey mixture.
  10. Top each pepper with one tablespoon grated Mozzarella.
  11. Bake at 375F/190C 30-40 minutes, or until the pepper is as done as you prefer and the cheese is starting to brown.

Southwestern Cauliflower Rice Stuffed Peppers

Prep Time 35 minutes
Cook Time 40 minutes
Total Time 1 hour 15 minutes

Southwestern Cauliflower Rice Stuffed Peppers make a perfect low-carb meal meal for anyone who likes Southwestern flavors!


  • 1 lb. ground turkey (see notes)
  • 4 olive oil, divided (or slightly more, depending on your pan)
  • 6 bell peppers, any color
  • 1 small onion chopped
  • 1 large Poblano pepper, finely chopped (see notes)
  • 1 teaspoon Kalyn’s Taco Seasoning (or use your favorite purchased Taco Seasoning Mix)
  • 1 tsp. Vege-Sal (or slightly less regular salt)
  • 1/2 large head cauliflower
  • 1 cup + 6 T grated low-fat Mozzarella


  1. Preheat oven to 375F/190C. Spray a baking dish with non-stick spray. (The best size is a dish that will barely fit all the peppers when they’re standing up.)
  2. Heat 2 teaspoons olive oil in a non-stick frying pan, add the ground turkey breaking it apart with your fingers as you put it in the pan, and cook turkey over medium-high heat until the turkey is completely cooked and starting to brown, about 10-12 minutes. Use your turner or a potato masher (affiliate link) to break the meat apart as it cooks. (Most ground turkey will release some water, just keep cooking and let that evaporate.)
  3. While the turkey cooks prepare the peppers. Slice off the stem end, discard the stem, and trim any white parts. Carefully slice off the bottom end, taking off just enough to make the pepper stand up straight. Put the peppers into baking dish. Chop the pepper ends and bottom pieces to make at least 1 cup diced peppers, saving the excess for another use if you have more than that.
  4. Finely chop the Poblano chile and chop the onion.
  5. Cut the cauliflower into small pieces and then pulse in a Food Processor (affiliate link) (or use a big hand grater) to make very small pieces, somewhat the size of cooked rice. (If you don’t start with small pieces in the food processor, you’ll have a hard time getting them all chopped evenly.)
  6. (I haven't tried making this with frozen cauliflower rice yet, but I think it would work if you prefer that. I would thaw the frozen cauliflower rice before you use it in the recipe.
  7. When the turkey is browned, remove to a plate, wipe out the pan, and heat the other 2 tsp. of olive oil. (You can also do this in a separate pan if you don’t want to wait.)
  8. Saute the onion about 2 minutes. Add taco seasoning and Vege-Sal (affiliate link) and cook about 1 minute more. Add the chopped bell peppers and Poblanos and saute about 2 minutes. Then add the chopped cauliflower and cook about 4-5 minutes, or until it’s starting to get soft.
  9. Stir in the browned turkey and turn off the heat. When the mixture has cooled slightly, stir in the 1 cup of cheese.
  10. Use a spoon to stuff each pepper with the mixture, pressing it down tightly with the spoon. (Holding each pepper over the pan is less messy than trying to stuff the peppers in the dish.)
  11. When all the peppers are filled, top each one with one tablespoon of grated Mozzarella.
  12. Bake 30-40 minutes, depending on how cooked you prefer the whole peppers (I like mine slightly crisp still) or until the cheese is lightly browned. Serve hot.


Use ground beef instead of turkey if you prefer. Poblano Peppers are often called Pasilla Peppers in U.S. grocery stores. I used Kalyn’s Taco Seasoning and Vege-Sal (affiliate link) for this recipe.

This will stay good in the fridge for several days and can be reheated in a microwave or in a toaster oven. Stuffed peppers can be frozen, but the pepper will definitely soften more when it’s frozen and thawed, so if you’re making extra to freeze I would take some out of the oven sooner than the ones you’re eating right away.
