Sometimes I 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, and that’s exactly what happened with this Brown Rice Casserole with Sausage and Peppers.

I had leftover brown rice and some turkey Italian sausage that I’d thawed out and never used. In the vegetable crisper I had 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.

And with only 1/4 cup cooked brown rice per serving, I’d still consider this to be a pretty carb-conscious meal. But see the link below for a version of this made with cauliflower rice.

How to Make Brown Rice Casserole with Sausage and 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. 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 Italian Herb Seasoning and cook for a minute or two. You can also add a little ground fennel if you enjoy the fennel flavor like I do.
  3. Remove onions and green peppers, squeeze turkey Italian sausage out of the casing, and cook sausage in the same pan until it’s nicely browned, breaking apart with the turner.
  4. Mix the vegetables and cooked brown rice into the pan 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, or more cheese if you prefer.
  7. Bake about 25 minutes, or just until the cheese is melted and nicely browned and the whole mixture is piping hot.

Brown Rice Casserole with Sausage and Peppers
Yield: Makes 6 servings

Brown Rice Casserole with Sausage and Peppers

Prep Time 20 minutes
Cook Time 35 minutes
Total Time 55 minutes

This Brown Rice Casserole with Sausage and Peppers is delicious and it's a perfect way to use leftover brown rice.

Ingredients

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

Instructions

  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.
  7. Squeeze the turkey Italian sausage out of the casing and cook 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.

Notes

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

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
The Brown Rice Casserole with Sausage and Peppers would be a great main dish for phase two or three of the original South Beach Diet, and it’s also gluten-free. There is definitely not much rice compared to the vegetable and protein ingredients so this is probably a lot lower in net carbs than you might think, but for low-carb and Keto diets you might prefer my Cauliflower Rice Sausage Casserole.
