A rich and hearty slow cooker beef bolognese sauce that simmers to perfection, perfect for serving over your favorite pasta.
1 tablespoon olive oil
1 medium yellow onion, finely chopped
2 medium carrots, finely chopped
2 celery stalks, finely chopped
4 garlic cloves, minced
1 pound ground beef
1/2 cup dry red wine
1 (28-ounce) can crushed tomatoes
2 tablespoons tomato paste
1 cup beef broth
1 teaspoon dried oregano
1 teaspoon dried basil
1/2 teaspoon dried thyme
1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon crushed red pepper flakes
1/4 cup whole milk
Heat olive oil in a large skillet over medium heat.
Add the chopped onion, carrots, and celery to the skillet and sauté for 5-7 minutes until softened.
Add the minced garlic and cook for 1 minute until fragrant.
Add the ground beef to the skillet and cook until browned, breaking it up with a spoon, about 5-7 minutes.
Transfer the beef and vegetable mixture to the slow cooker.
Pour the dry red wine into the skillet and stir to deglaze the pan, scraping up any browned bits. Let it simmer for 2 minutes.
Add the wine and all remaining ingredients except the milk to the slow cooker and stir to combine.
Cover and cook on low for 6 hours.
About 15 minutes before serving, stir in the whole milk and cook uncovered for the remaining time.
Serve the bolognese sauce hot over cooked pasta of your choice.
