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 but 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!

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 if you like fennel if you like that 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. This is my 3rd attempt to post my comment, so fingers crossed. Like another poster, I used a full "recipe" of day-old brown rice (1 cup uncooked, which is well more than 1.5 cups cooked). I also added several cloves of minced garlic and a small can of (organic) petite-diced tomatoes, drained, when adding the spices. For the cheese topping, I used 1 cup of freshly-grated organic white cheddar along with some freshly-grated parmesan. I baked it, in a large casserole dish, covered for 24 minutes, and uncovered for 6 minutes. Hubby tried to eat the whole thing! It was like stuffed peppers in casserole form. 🙂

  2. Wonderful, purley comfort food in our home.
