Sometimes I just pull leftovers out of the fridge and come up with something that turns out so well I make the recipe again to take photos for the blog.  That’s exactly what happened with this Easy Brown Rice Casserole with Italian Sausage and Green Pepper.  I had leftover brown rice and some turkey Italian sausage that I’d thawed out and never used. In the vegetable crisper I had those 2/$1.00 green bell peppers that are so good this time of year. I cooked those things together into a tasty casserole topped with cheese and decided it was a keeper, so a few days later I made it again and took these photos.

I know it’s January now and lots of you are looking for ultra low-carb recipe ideas although with less than 1/2 cup brown rice, I’d still consider this to be a carb-conscious meal. So in 2020 I made Low-Carb Cauliflower Rice Sausage Casserole, which is a low-carb variation of this recipe. Both versions are delicious; give one of them a try!

What ingredients do you need for this recipe?

  • onion
  • green bell pepper
  • olive oil
  • Italian Herb Seasoning (affiliate link)
  • ground fennel (affiliate link)
  • turkey or pork Italian sausage
  • cooked brown rice
  • Mozzarella cheese (I used a four cheese blend)

How to Make Easy Brown Rice Casserole with Italian Sausage and Bell Pepper:

(Scroll down for complete printable recipe, including nutritional information.)

  1. Finely chop a large onion and a green bell pepper.
  2. Saute the onion and bell pepper in some olive oil. When they’re almost done, mix in 1 tsp. Italian Herb Seasoning (affiliate link) and cook for a minute or two.  You can also add a little ground fennel (affiliate link) if you like that fennel flavor like I do.
  3. Remove the sauteed onions and green peppers, squeeze turkey Italian sausage out of the casing, and saute in the same pan until it’s nicely browned, breaking apart as it cooks.
  4. Mix the sauteed vegetables and cooked brown rice in with the sausage and warm it for a few minutes.
  5. Put the mixture into a casserole dish that you’ve sprayed with olive oil or non-stick spray.
  6. Top with about 3/4 cup of cheese.  I used a four-cheese blend from Costco.
  7. Bake about 25 minutes, or just until the cheese is melted and nicely browned and the whole mixture is piping hot.

Make it a Meal:

If you wanted a low-carb side dish I’d eat this with something like Not-so-Dumb Salad with Cucumbers, Tomatoes, Onions, Avocado, and Balsamic Vinegar; Cucumbers Caesar; or Red Rock Brewery Style No-Mayo Vinegar Coleslaw with Oregano.

Easy Brown Rice Casserole with Turkey Italian Sausage and Green Bell Pepper

Yield Makes 5 servings
Prep Time 20 minutes
Cook Time 37 minutes
Total Time 57 minutes

This Easy Brown Rice Casserole is delicious and has become a favorite casserole.


  • 1 medium onion, finely chopped
  • 1 green bell pepper, stem and seeds removed and finely chopped
  • 4 tsp. olive oil (divided)
  • 1 tsp. Italian herb seasoning (see notes)
  • 1/4 tsp. ground fennel (or more, optional)
  • 1 19.5 oz. pkg. turkey Italian sausage
  • 1 1/2 cups cooked brown rice
  • 3/4 cup cheese (I used a four cheese blend)


  1. Preheat oven to 375F/190C.
  2. Heat 2 tsp. olive oil in a large heavy frying pan.
  3. Add the chopped onion and green bell pepper and saute until the vegetables are cooked through, about 3-4 minutes.
  4. Add the Italian Herb Seasoning (affiliate link) (and ground fennel if using) and saute 1-2 minutes more.
  5. Remove the cooked vegetables to a bowl.
  6. Add 2 tsp. more oil to the frying pan (or less if you’re using a non-stick pan.)
  7. Squeeze the turkey Italian sausage out of the casing and saute until it’s fully cooked and nicely browned, breaking apart with a turner as it cooks.
  8. This will take about 5-6 minutes, but don’t rush the browning.
  9. When sausage is done put the cooked vegetables and brown rice into the pan and mix with the sausage.
  10. Cook this mixture a few minutes, until the rice is warmed through.
  11. Put the mixture into a casserole dish that you’ve sprayed with olive oil or non-stick spray.  (I used a dish that was 7″ x 9″ but a slightly larger size will work.)
  12. Sprinkle the cheese over the top.
  13. Put the casserole into the oven and bake until the cheese is melted and lightly browned and the whole thing is piping hot, about 20-25 minutes.
  14. Serve hot.
  15. This kept well in the fridge and reheated well in the microwave, although the green pepper flavor was stronger after it was reheated.


The Italian Herb Seasoning (affiliate link) I used is a mix of dried oregano, marjoram, thyme, and rosemary.

This recipe created by Kalyn as a way to use leftover brown rice she had in the fridge.

  1. Sounds absolutely delicious, I love rice casseroles with sausage or ground meat. My kids too, so I put this on the list. 🙂

  2. Thank you for posting this recipe! My boyfriend and I definitely enjoyed it! It was so simple and tasted very good.


  3. Thanks Peggy!

  4. Happy Birthday Kalyn and Best Wishes for much happiness and success in the year ahead, especially with your wonderful blog!

  5. Donna, how fun! I love that I am sharing your mom's birthday! xoxo

  6. Oh My Gosh. TWO of my favorite women/mentors/heros have the same birthday! You and my mom have the same birthday. They are smart to name you the queen.

  7. Shulie, I think one reason I love casseroles so much is the leftovers! But you're right, they're perfect for cold weather too.

  8. I almost never make casserole but they are such comforting dishes easy to reheat. I should now as they are absolutely perfect for this wintery weather, though been warm here in the DC area.

  9. Kalyn, fennel is great with ground venison. I usually add it when making venison sausage. 🙂

    My pleasure to share, as always.

  10. Thanks for the birthday wishes everyone. I did have a wonderful birthday!

    Shirley, would love to hear how thsi works with ground venison. Would fennel complement that? That would kind of simulate the flavor of the spices? Thanks for sharing!

  11. This looks like healthy comfort food, Kalyn. Might have to try it with ground venison soon. Shared on FB. 🙂

    Happy Sunday!

  12. Congrats love! ANd happy belated birthday!

  13. Happy Birthday to you!!

    I came across your site recently and you have an amazing site. Did try Onion gratin, stuffed green pepper and stuffed mushrooms already. Turned out amazing while helping me stick to a healthy diet.. Thank You!!

  14. I love this. I added some black beans as well, and the tiniest touch of BBQ sauce when serving. Yum, and great to take to work.

    Happy Birthday week:-)

  15. Made this for dinner yesterday and it was great, and the left overs were even better. I think next time I'll add more peppers and mix the cheese in. But another winner — thanks!

  16. So glad you liked it! I just bought black rice for the first time and can't wait to experiment with it!

  17. we tried this tonight for dinner but I only had black rice which is even better for you than brown so it worked out great. It was delicious and my husband LOVED it!!

  18. Seasonsmom, glad you enjoyed it.

    One reason I chose the South Beach Diet to manage my weight was because I didn't want to have to count the calories, carbs, or points for everything I ate. Since I already spend 4-5 hours on every recipe and I'm not calculating that information for my own use, I'm not able to include it for recipes on the blog. If you want to figure out the nutritional information yourself, a site that's very easy to use is Calorie Count. Just copy the recipe and enter the number of servings and it will calculate everything for you. (You may have to edit to remove some extra descriptive words in the recipe or change things like 2 tsp. + 1 tsp. to say 3 tsp., but it's really very easy to use.)

  19. just curious to what the caloric breakdown is…. Couldn't find it anywhere on the site

  20. I loved it. My kids don't like brown rice plain, esp served with beans. I love the nutty texture of brown rice. I cooked a rice cooker full and already had some ground chicken with red pepper and onions sauteed a few days prior. Throwing this together was so easy! Hubby ate 2 servings. The cheese on top under the broiler was nice and crunchy!!! I will try it with quinoa next time!
