Ingredients
For the Bolognese Sauce
- 500g ground beef
- 1 large onion, finely chopped
- 3 garlic cloves, minced
- 2 carrots, grated
- 2 celery stalks, finely chopped
- 2 tablespoons tomato paste
- 1 can crushed tomatoes
- 1 cup beef broth
- 1 tablespoon olive oil
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1 bay leaf
- Salt and black pepper to taste
- 1 teaspoon sugar
- Optional: chili flakes for a little heat
For Serving
- Spaghetti pasta
- Parmesan cheese
- Fresh basil or parsley
Step-by-Step Instructions
Step 1: Brown the Meat
Although the slow cooker does most of the work, browning the beef first adds a huge amount of flavor to the final sauce.
Heat olive oil in a large pan over medium heat. Add the chopped onion and cook for 2–3 minutes until soft. Stir in the garlic, carrots, and celery, cooking for another few minutes until fragrant.
Add the ground beef and cook until browned, breaking it apart with a wooden spoon as it cooks. Drain any excess grease if needed.
This step creates a richer and more flavorful Bolognese sauce.
Step 2: Add Everything to the Slow Cooker
Transfer the beef mixture into the slow cooker. Add:
- Crushed tomatoes
- Tomato paste
- Beef broth
- Oregano
- Basil
- Bay leaf
- Sugar
- Salt and pepper
Mix everything together well.
The sauce may look slightly thin at first, but after several hours of cooking, it will become thick, rich, and packed with flavor.
Step 3: Slow Cook to Perfection
Cover the slow cooker with the lid and cook:
- On LOW for 6–8 hours
or - On HIGH for 3–4 hours
As the sauce slowly cooks, the ingredients blend beautifully together. The tomatoes become sweeter, the herbs become more aromatic, and the meat absorbs all the delicious flavors.
Your kitchen will smell absolutely amazing.
Cooking the Spaghetti
About 15 minutes before serving, cook the spaghetti according to the package instructions in salted boiling water until al dente.
Drain the pasta and reserve a small amount of pasta water. Adding a splash of pasta water to the sauce helps create a silky texture that coats the spaghetti perfectly.
How to Serve
Place a generous portion of spaghetti onto a plate or bowl and spoon the rich Bolognese sauce over the top.
Finish with:
- Freshly grated Parmesan cheese
- Chopped parsley or basil
- A drizzle of olive oil if desired
Serve with:
- Garlic bread
- Caesar salad
- Roasted vegetables
- A glass of red wine for a restaurant-style dinner
