Ingredients
Method
- Heat 1½ tablespoons olive oil in a large skillet over medium high. Salt and pepper both sides of chicken. Once oil shimmers, add in one layer. Brown 3 to 4 minutes with minimal movement; turn and cook 3 to 4 minutes more. Remove; set aside.
- In the same skillet, heat ¾ tbsp oil over medium. Sauté onion, garlic, and oregano until fragrant.
- Add 1½ tablespoons balsamic vinegar; cook 1 minute until reduced.
- Heat slow cooker on low.
- Add onion mixture and chicken. Top with tomatoes, broth, green bell pepper, mushrooms, olives, and 3 teaspoons basil. Season with salt and pepper.
- Cover; cook on low approximately 3 hours or until chicken reaches 165°F (74°C). Remove chicken; set aside.
- Cook sauce uncovered on high for 30min to thicken and develop flavor. Before serving, stir in remaining ¾ teaspoon balsamic vinegar; taste and adjust salt and pepper. Return chicken; gently coat. Serve hot with pasta, rice, or creamy polenta, remaining sauce, and remaining ¾ teaspoon fresh basil.
Notes
If you do not have time and need the sauce quickly whisk together 1 tablespoon cornstarch with 1 tablespoon water and 1 tablespoon of your sauce. Then, stir this mixture into the slow cooker and let simmer until thickened.
