Ingredients:
- 1.5 lb 90/10 ground beef
- 2 tablespoons olive oil
- 1 cup diced yellow onion
- 1 cup diced carrots
- 1 cup diced celery
- 4 cloves garlic, minced
- 1/2 cup dry red wine (Merlot or Cabernet Sauvignon)
- 1/2 cup beef broth
- 2 (28 ounce) cans crushed tomatoes
- 1 (6 ounce) can tomato paste
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1.5 teaspoons kosher salt
- 1/2 teaspoon black pepper
Instructions:
- Heat olive oil in a large skillet over medium-high heat. Add the ground beef and brown thoroughly, breaking it up as it cooks (approximately 8 minutes). Drain off excess fat. Add the diced onion, carrots, and celery (Mirepoix) and cook until slightly softened, about 5 minutes. Stir in the minced garlic for the last minute.
- Pour the red wine into the skillet and scrape up any browned bits from the bottom. Let the wine reduce slightly (about 2 minutes). Transfer the meat and vegetable mixture immediately into the slow cooker basin.
- Add the crushed tomatoes, tomato paste, beef broth, oregano, basil, salt, and pepper to the slow cooker. Stir well to combine all ingredients. Cover and cook on HIGH for 4 hours, or on LOW for 8 hours, until the sauce is thick and the flavors have fully melded.
- Taste and adjust seasoning if necessary. Serve hot over pasta, polenta, or use as a base for lasagna.
