Readers and people who have used this recipe had a number of suggestions for changes, including different types and flavors of rice, other sauces, and some excellent seasoning ideas. See the tips and variations below the recipe instructions for some possible substitutions and flavor ideas.

Since the ground beef is not browned ahead of time, I would use at least 90% lean beef in this recipe. Ground turkey would make a good, lean filling as well.


  • 4 medium green bell peppers (or use multicolored)
  • 1 pound ground beef (lean)
  • 1/4 cup onion (finely chopped)
  • 1 1/2 cups rice (cooked)
  • 1 teaspoon seasoned salt ​(or a Creole seasoning blend)
  • 1/2 teaspoon black pepper
  • 1 (32-ounce) jar spaghetti sauce (or marinara sauce)

  7. To check for doneness, insert an instant-read food thermometer into the center of the filling. It should read at least 160 F (71 C) or 165 F (74 C) for ground turkey.

Tips and Variations

  • Substitute 1 cup of uncooked white or brown Minute Rice for the cooked rice.

  • Instead of ground beef, use ground turkey in the filling.

  • Substitute an (8.8-ounce) package of Uncle Ben's Ready Rice for the cooked rice.

  • Substitute 1 (14.5 -ounce) can of diced tomatoes and 1 (10 3/4-ounce) can condensed tomato soup for the spaghetti sauce. Combine the two in a bowl and pour over the peppers.

  • Chop the tops of the peppers finely and add them to the filling or to the sauce mixture.

  • Instead of plain white rice, add cooked Mexican or Spanish rice to the beef mixture. Use Uncle Ben's Ready Rice or Rice-a-Roni brand.

  • For Tex-Mex or Mexican flavors, substitute 2 (14.5-ounce) cans of chili style or Mexican style tomatoes for the spaghetti sauce.
