Heat olive oil in a skillet over medium heat. Add the chopped onion and minced garlic, and sauté until the onion is translucent, about 3-5 minutes.
Add the ground beef to the skillet. Cook, breaking up the meat with a spoon, until browned and cooked through.
Transfer the cooked meat and onion mixture to the slow cooker. Add the crushed tomatoes, tomato paste, dried oregano, dried basil, salt, and black pepper. Stir well to combine.
Cover and cook on low for 6-8 hours or on high for 4-5 hours, until the sauce is thick and flavorful.
Serve the Bolognese sauce over cooked pasta of your choice, and garnish with grated Parmesan cheese, if desired.
There you have it—a simple yet satisfying slow cooker Bolognese sauce that is sure to become a cherished addition to your family’s mealtime traditions. Enjoy every comforting bite!
