brown rice casserole

It’s been a long time since I’ve posted a recipe with the word “casserole” in the title, but lately I’ve been in a casserole kind of mood. It’s not just that I’ve been hearing casseroles are back or that some people have called them The Ultimate Recession Food. When I was growing up, casseroles were always a regular part of the menu.

When I first started the blog I made a lot more casseroles than I have the last few years, even adapting some of my favorite casserole recipes to make them more carb-conscious or South Beach Diet friendly. I know plenty of people who read the blog are cooking for families, and lately I’m thinking a few more casserole options might be a good thing. (If you have an opinion on casseroles, please weigh in with a comment.)

This casserole started with lots of onions and diced red bell peppers, sauteed in olive oil with a bit of Greek seasoning. Then I added some brown rice that I’d cooked the day before in the rice cooker, and cooked it just enough to warm the rice. (Note: I used my Zojirushi 3-Cup Rice Cooker to cook the rice. I love this rice cooker. It’s definitely an investment, but it makes perfect brown rice every time.)

Then I turned off the heat and stirred in some crumbled feta cheese and just a tiny bit of chicken stock to keep it moist. Put this in the cassserole dish and bake at 375F/190C about 30 minutes.  Simple, and delicious as a main dish or side dish. (This could also be a vegetarian main dish if you substitute vegetable stock for the chicken stock.)

Make it a Meal:

Serve this Greek-Inspired Brown Rice Casserole as a vegetarian main dish with something like Pan-Fried Asparagus Tips. This would also make a great side dish for something like Very Greek Grilled Chicken or Kalyn’s Souvlaki.

Greek-Inspired Brown Rice Casserole with Red Pepper, Onions, and Feta

This Greek-Inspired Brown Rice Casserole with Red Pepper, Onions, and Feta is a perfect idea for leftover brown rice!


  • 4 cups cooked leftover brown rice
  • 1 T olive oil
  • 1 large onion, chopped fairly small
  • 1 large red bell pepper, diced into 1/2 inch pieces
  • 2 tsp. Greek Seasoning (I use Penzeys Greek seasoning, which is a mixture of salt, Turkish oregano, garlic, lemon peel, black pepper, and marjoram.)
  • 6 oz. crumbled feta cheese (about 1 cup, don’t buy pre-crumbled feta, buy a block and crumble it)
  • 1/4 cup chicken stock, preferably homemade chicken stock


  1. Preheat oven to 375F/190C.
  2. Chop onion and red pepper.
  3. Heat 1 T olive oil in heavy frying pan, add onion and saute over medium-high heat about 2 minutes.
  4. Add red pepper and Greek seasoning (I use Penzeys Greek seasoning) and saute 2-3 minutes more.
  5. Add rice and saute about 1 minute, stirring with a turner so the veggies are evenly distributed in the rice.
  6. Turn off heat and gently stir in crumbled feta cheese and pour over chicken stock ( I use homemade chicken stock.)
  7. Spray a glass or ceramic casserole dish with olive oil or non-stick spray, then pour in rice mixture and spread around in an even layer.
  8. Cover casserole and bake about 25 minutes.
  9. Remove lid and bake about 5-10 minutes more, until cheese looks slightly melted. Serve hot.

  1. I'm totally in favor of people substituting in ingredients that they like!

  2. This looks great! I think I may sub kalamatas for the red pepper. I'm just not a pepper fan! Or maybe sun dried tomatoes?!

  3. Thanks Elizabeth; hope you enjoy it!

  4. This sounds amazing! I can't wait to give it a try!

  5. I cook my brown rice in my toaster oven, using an 8×8 pyrex dish. Leftovers go in the fridge for upcoming meals. I use l/o for casseroles like this and use spinach, feta and whatever looks right. It ends up tasting like south beach spinach pie. Nice side-dish and any leftovers that happen are a nice lunch.

  6. This looks absolutely delicious and could easily be converted to be vegetarian (as well as naturally being gluten-free). YUM! Thanks for the inspiration!


  7. Abbey, glad you liked it, and I love the idea of adding a bit of soy sauce. That set my mind racing thinking of more casserole ideas!

  8. Tried this last night with some red peppers and onions that I had left over from a stir fry, loved it! At the suggestion of my husband, I added a few tablespoons of soy sauce. What a great use for leftovers!

  9. John, you are right of course. I guess in my mind, I always just assume that someone who’s a vegetarian would substitute vegetable stock, but I should have made that clear. Will edit.

  10. Hi Kaylyn –
    I like the sound of your casserole, and we are going to have a vegetarian potluck at work next week. My question is, How can this be called vegetarian if there is chicken stock in it. I’ve noticed this in other recipes, on other sites. I just don’t get it.

  11. Susan, I’m looking in South Beach Diet Supercharged (the newest book) and lemon juice, avocado, and olive are all listed for phase one. (limited quantities for olive and avocados, 15 olives or 1/2 avocado.) I don’t see pickles listed, but cucumbers are okay and I can’t think of any reason pickles wouldn’t be allowed.

  12. Hi Kalyn,
    I am new to your blog and to South Beach but I am loving both. I’m on day 3 of phase 1. I have a couple of simple questions that i don’t see in the book. Perhaps you or your readers can help me?
    Here is a list of foods that I’d like clarification on. Can i eat them in Phase 1 or just 2 or not at all?
    -Lemon Juice
    -Olives (black, Spanish etc…)

    Thank you so much.

  13. I’m not a huge rice lover but with a little extra feta cheese this sounds like a great side dish.

  14. Mrs. D, perfect side dish for those Greek dishes, thanks for sharing that idea.

    Thanks to all for the casserole feedback too!

  15. I made this last nite for dinner as a side for Greek Meatballs and Tzsacki sauce (another KK favorite recipe) My husband, who is not a big fan of casseroles, LOVED IT!
    It was very good- easy to make and healthy. Thx Kaylyn for yet another delicious recipe. This one is a keeper

  16. Casseroles are great! And this one sounds fantastic! 🙂

  17. I don’t think I ever made any casserole dish… But this one might just make me make the first one ever! Looks delicious!

  18. Nothing so cozy and inviting as a brown rice casserole- baking rice with veggies, etc is my favorite thing to do. Beautiful photo, too, Kalyn. I love the colors.

  19. Sorry to get so behind on responding to comments. I went with my sister today to take my dad to see the assisted living center where we’re moving him. Kind of an emotionally charged day, but I was relieved that the place was so nice.

    Glad you guys are into the casserole idea. This was really good, and pretty healthy with the brown rice too.
