Vegetarian Stuffed Peppers
These Vegetarian Stuffed Peppers have mushrooms and Feta, and you can make them with cooked brown rice or cauliflower rice! And no matter which version you choose, these tasty stuffed peppers are also gluten-free.
Recently on the Kalyn’s Kitchen Facebook page a reader asked whether I had a stuffed pepper recipe that was vegetarian. That inquiry started the idea of vegetarian stuffed peppers swirling around in my mind, and this week when I got together with Jake for a day of cooking, we came up with these Vegetarian Stuffed Peppers.
The peppers are stuffed with brown rice or cauliflower rice that’s combined with sauteed onion, chopped peppers, chopped mushrooms, and crumbled Feta. We loved everything about this recipe, and if you can’t eat six peppers at once, take some out of the oven a little sooner and freeze for a quick dinner later.
What ingredients do you need for this recipe?
- bell peppers
- cooked brown rice (or use 10 oz. package frozen cauliflower rice for low-carb version)
- Olive Oil (affiliate link)
- Greek Seasoning (affiliate link)
- fresh ground black pepper to taste
- crumbled Feta cheese
Do you need to pre-cook the peppers?
I’ve been making stuffed peppers and low-carb stuffed peppers for many years, and I discovered a long time ago that I prefer stuffing the peppers raw so they’re still just barely crisp when they’re done.
What color of peppers can you use?
I love to use brightly-colored red, orange, and yellow peppers but you can make stuffed peppers with any color you have. And if you were making this during the holidays it would be fun to make the stuffed peppers red and green.
How can you make Vegetarian Stuffed Peppers lower in carbs?
The nutritional information in this recipe is for the original stuffed peppers made with brown rice, and each pepper has 24 net carbs. But if you replace the cauliflower rice with a 10 oz. package of frozen cauliflower rice, each pepper will be 12.1 net carbs. Cook the cauliflower rice just slightly less time than the package indicates, since it will cook more inside the peppers.

How to make Vegetarian Stuffed Peppers:
(Scroll down for complete printable recipe, including nutritional information.)
- I cooked the brown rice in my much beloved Zojirushi Rice Cooker, but if you don’t have a rice cooker just follow package directions to get 2 cups of cooked brown rice. (For cauliflower rice version, follow package directions but cook the cauliflower rice for slightly less time.)
- You need some chopped pepper for the filling, so don’t feel bad about slicing off the bottom (to make the peppers stand up straight) and slicing off the top. (I bought a six-pack of multi-colored peppers from Costco.)
- Clean out the seeds and inner membranes of the peppers and stand them up in a baking dish that you’ve sprayed with non-stick spray.
- Chop up 12 ounces of mushrooms. (I used brown Crimini mushrooms, which I think are especially flavorful.)
- Also finely chop the pepper tops and bottoms and one small onion.
- Saute the onions and peppers for a few minutes and remove to a plate.
- Then saute the chopped mushrooms until they’re starting to brown (and all liquid has evaporated.)
- Add the onions and peppers to the mushrooms, add the Greek Seasoning and black pepper to taste and cook about a minute more.
- Turn off heat and mix in the cooked brown rice (or cauliflower rice) and 1 cup of crumbled Feta. (If you’re a strict vegetarian, look for a Feta cheese with vegetable rennet.)
- Stuff the filling into the peppers, pressing it down with a spoon. (Remove one pepper at a time and hold it over the frying pan to stuff to keep the baking dish clean!)
- Cover the baking dish with foil and cook 30 minutes in a pre-heated oven at 375F/190C. (Cook about 25 minutes for cauliflower rice)
- Then put about 2 tsp. crumbled Feta on the top of each pepper, pressing it down so it will stay.
- Bake about 20 minutes more uncovered, until the Feta is melted and starting to slightly brown and the peppers are done to your liking.
- Serve hot and enjoy!

- 6 fresh bell peppers, any color (bottoms and tops sliced off)
- 2 cups cooked brown rice (or 10 oz. package frozen cauliflower rice)
- 4 tsp. olive oil
- 1 onion, finely chopped
- 12 oz. mushrooms, chopped small (see notes)
- 2 tsp. Greek Seasoning (or a little more)
- fresh ground black pepper to taste
- 1 1/4 cups crumbled Feta cheese
- Follow package directions to cook 2 cups brown rice. I use Uncle Ben’s Brown Rice which I cook in my Zojirushi Rice Cooker (affiliate link). For frozen cauliflower rice, follow package directions but cook the cauliflower rice for slightly less time.
- Preheat oven to 375F/190C. Choose the smallest possible baking dish that will hold all six peppers standing up, and spray with nonstick cooking spray or olive oil.
- Cut off the bottoms of the peppers, cutting off as little as possible to make a flat bottom so the peppers will stand up. (Don’t worry if it leaves a small hole.)
- Slice off the tops of the peppers, cutting off just enough to cut away the stem part. Remove any seeds and membranes from inside the peppers and stand them up in baking dish.
- Finely chop the pepper tops and bottoms that you sliced off, as well as the onion.
- Wash mushrooms if needed, and chop into pieces just slightly larger than you chopped the peppers and onions.
- Heat 2 tsp. of oil in a large non-stick frying pan, add onions and peppers, and saute over medium-high heat until they’re barely starting to soften, about 4 minutes.
- Remove to a plate, add 1 tsp. more oil to pan, add chopped mushrooms, and cook until the mushrooms have released their liquid, the liquid has evaporated, and mushrooms are barely starting to brown, about 6 minutes.
- Put the sauteed onions and peppers back into the pan with the mushrooms, add the Greek Seasoning and black pepper to taste, and cook 1 minute more. Stir in the cooked rice (or califlower rice) and add 1 cup of the crumbled Feta and gently combine.
- One at a time, hold each pepper over the frying pan and fill with the stuffing, pressing it down as much as you can so it’s tightly packed. (We didn’t have any extra stuffing, but if you do, just cook it along with the peppers either in the same dish or in a small casserole dish.)
- When all peppers are stuffed, cover the baking dish with foil (or a lid if it has one) and cook 30 minutes.
- After 30 minutes, remove dish from the oven and remove the foil. Put 2 tsp. crumbled Feta on the top of each pepper, pressing it down a little if needed to get it to stick.
- Bake 20 minutes more, until the Feta is starting to melt and lightly brown and peppers are done to your liking. Serve hot and enjoy!
I used brown Cremini mushrooms, also called Baby Bellas.
If you won’t be eating all six peppers at once, take some out of the oven a little sooner and freeze in an air-tight container to be reheated for a quick dinner later. For best results, let frozen peppers thaw in the fridge and then reheat in the microwave or in the oven in a small baking dish covered with foil.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Peppers, onions, mushrooms, brown rice, and Feta cheese are all good for the original South Beach Diet Phase two or three. Vegetarian Stuffed Peppers with brown rice would be too high in carbs for low-carb diets but the version with cauliflower rice would be a good option and also suitable for Phase one for the South Beach Diet. If you make the version with cauliflower rice the peppers will have only 12.1 net carbs per pepper.
