Pomegranate Beef in the Crockpot

1 tablespoon olive oil
1 yellow onion, sliced
1/4 teaspoon ground cinnamon
1 teaspoon herbes de Provence
1/2 teaspoon kosher salt
3 pounds beef roast (chuck roast works)
4 garlic cloves (whole is fine, or you can chop them)
1 (14-ounce) can fire-roasted crushed tomatoes
1 cup unsweetened pomegranate juice
1/4 cup balsamic vinegar
2 tablespoons maple syrup
1/2 cup golden raisins

1. Use at least a 6-quart slow cooker. Swirl the olive oil into the bottom of the stoneware. Add the onion. Rub the spices on all sides of meat and add to the stoneware with the garlic, the whole can of tomatoes, pomegranate juice, vinegar, and syrup. Sprinkle the raisins on top.
2. Cover and cook on low for 8 hours, or on high for about 5. The meat is done when it has reached desired tenderness. Serve with mashed potatoes, and drizzle with the sauce.
