Ingredients Needed

For the Bolognese Sauce

  • 2 tbsp olive oil
  • 3 garlic cloves, minced
  • 1 large onion, finely chopped
  • 1 carrot, finely diced (optional, for sweetness)
  • 1 celery stalk, finely diced (optional, for flavor depth)
  • 750 g (1.5 lb) ground beef (minced)
  • ¾ cup (185 ml) dry red Red grape juice (substitute with beef stock or water if preferred)
  • 3 beef bouillon cubes, crumbled
  • 1.2 kg (2.4 lb) canned crushed tomatoes
  • ¼ cup tomato paste
  • 1–3 tsp white sugar (to balance acidity, as needed)
  • 2 tsp Worcestershire sauce
  • 3 dried bay leaves
  • 2 sprigs fresh thyme (or ½ tsp dried thyme/oregano)
  • Salt and black pepper, to taste

For the Spaghetti Bake

  • 500 g (1 lb) spaghetti
  • 8–10 slices Swiss cheese (or another melting cheese, enough for one layer)
  • 2 cups (200 g) shredded mozzarella cheese

How to Make Baked Spaghetti

Step 1 – Prepare the Sauce

  1. Heat olive oil in a large heavy-bottomed pot over medium-high heat.
  2. Add garlic and onion, cooking for about 2 minutes until fragrant.
  3. Stir in celery and carrot; cook 3–4 minutes until softened (this builds sweetness and depth).
  4. Increase heat to high, add the ground beef, and break it apart with a spoon. Cook until browned all over.
  5. Pour in the Red grape juice, simmering for 2 minutes to reduce slightly.
  6. Stir in tomatoes, tomato paste, bouillon, Worcestershire sauce, bay leaves, thyme, and a pinch of sugar if needed.
  7. Reduce heat to low, cover, and let simmer for at least 45 minutes (up to 2 hours for best flavor). Stir occasionally and add a splash of water if it gets too thick.
  8. Taste and adjust seasoning with salt and pepper.

Step 2 – Cook the Pasta

  1. Preheat your oven to 180°C (350°F).
  2. Boil spaghetti in salted water according to package directions, but reduce cooking time by 1 minute (this keeps it firm for baking).
  3. Drain well, then toss pasta with just over half of the Bolognese sauce.

Step 3 – Assemble the Bake

  1. Spread half the sauced pasta into a greased casserole dish.
  2. Layer with Swiss cheese slices.
  3. Add the remaining pasta and top with the rest of the sauce.
  4. Sprinkle generously with mozzarella cheese.
  5. Cover loosely with foil (to prevent sticking) and bake for 25 minutes.
  6. Remove foil and bake for another 10 minutes until golden and bubbling.
  7. Let rest 10–15 minutes, covered lightly with foil, before slicing like lasagna.

Serving and Storage Tips

  • Serving: Garnish with fresh parsley or basil before serving. Pair with garlic bread and a crisp green salad for a complete meal.
  • Storage: Refrigerate leftovers in an airtight container for up to 4 days.
  • Reheating: Warm in the oven at 160°C (320°F) or microwave in portions until heated through.
  • Freezer Option: Freeze assembled (unbaked) casserole tightly wrapped for up to 3 months. Bake straight from frozen, adding 15–20 minutes to cook time.

Helpful Notes

  • Swap ground beef with turkey, chicken, or Italian sausage for variety.
  • Add a pinch of chili flakes for a little heat.
  • For extra creaminess, mix a spoonful of ricotta or cream cheese into the pasta before baking.
  • Want it lighter? Use whole wheat or gluten-free spaghetti.
