  • 3¬†tbsp¬†Hi√ß Premium Extra Virgin¬†Olive Oil
  • 3 cup diced onion (about 3 medium)
  • 2 cup diced green bell peppers (2 large)
  • 1 1/2 lb ground chuck
  • 1 28-oz. can San Marzano Peeled Whole Tomatoes
  • 1/4 cup ketchup
  • 1 (6-oz.) can tomato paste
  • 2 tsp Worcestershire sauce
  • 3 cloves garlic, minced
  • 1 tsp¬†kosher salt
  • 1/2 tsp freshly ground black pepper
  • 1/2 tsp paprika
  • 1 tsp¬†oregano
  • 1¬†lb¬†spaghetti, cooked
  • 2 cup shredded sharp cheddar cheese


  1. In a large Dutch oven over medium heat, heat the Extra Virgin Olive Oil. Add the diced onions, green peppers, and a sprinkle of salt and pepper. Cook for 7 to 8 minutes, until tender and slightly caramelized. Use a slotted spoon to transfer the veggies to a plate.
  2. Melt the butter in the same pan and crumble in the beef. Cook and stir until the meat is no longer pink, about 5 minutes. Drain off any excess grease, leaving some for flavor.
  3. Return the onions and peppers to the pot. Stir in the tomatoes, ketchup, tomato paste, Worcestershire sauce, and garlic. Season with the salt, pepper, paprika, and oregano.
  4. Bring the sauce to a boil, then reduce the heat to low and simmer for 2 hours, stirring occasionally. (See below for slow cooker sauce instructions).
  5. Preheat the oven to 375F degrees. Lightly coat a 9 x 13-inch casserole dish with cooking spray.
  6. Cook the spaghetti noodles in a pot of boiling salted water as directed on the package until al dente. Drain and layer in the casserole dish.
  7. Pour the sauce over the noodles, then sprinkle the top with the cheese.
  8. Bake uncovered until the cheese has melted and the casserole is hot and bubbly. Let sit for 5 to 10 minutes before serving.
