Chef John’s Stuffed Peppers

1 cup white rice

2 cups water

1 tsp salt

1 onion, diced

1 tablespoon olive oil

2 cups tomato sauce (two 8 ounce cans)

1 cup beef broth

1 tablespoon balsamic vinegar

1/4 teaspoon crushed red pepper flakes

1 pound ground beef

1/4 pound hot Italian sausage (casing removed)

1 (10 ounce) can diced tomatoes

1 tablespoon parsley

4 cloves garlic, minced

2 teaspoons salt

1 teaspoon pepper

1 pinch cayenne pepper

4 large green bell peppers, halved and seeded

1 cup Parmesan cheese

  1. Preheat the oven to 375 degrees F (190 degrees C).
  2. Bring rice, water, and 1 teaspoon salt to a boil in a saucepan over high heat. Reduce heat to medium-low, cover, and simmer until the rice is tender, and the liquid has been absorbed, 20 to 25 minutes. Set the cooked rice aside.
  3. Cook onion and olive oil over medium heat until onion begins to soften, about 5 minutes. Transfer half of cooked onion to a large bowl and set aside.
  4. Stir tomato sauce, beef broth, balsamic vinegar, and red pepper flakes into the skillet; cook and stir for 1 minute.
  5. Pour tomato sauce mixture into a 9×13-inch baking dish and set aside.
  6. Combine ground beef, Italian sausage, diced tomatoes, Italian parsley, garlic, salt, black pepper, and cayenne pepper into bowl with reserved onions; mix well. Stir in cooked rice and Parmigiano Reggiano. Stuff green bell peppers with beef and sausage mixture.
  7. Place stuffed green bell pepper halves in the baking dish over tomato sauce; sprinkle with remaining Parmigiano-Reggiano, cover baking dish with aluminum foil, and bake in the preheated oven for 45 minutes.
  8. Remove aluminum foil and bake until the meat is no longer pink, the green peppers are tender and the cheese is browned on top, an addition 20 to 25 minutes.
