This Slow Cooker Tomato Basil Chicken is a delicious and effortless Italian-American fusion dish that's perfect for busy weeknights.Tender chicken breasts are slow-cooked in a rich tomato sauce infused with fresh basil and aromatic herbs.
Start by trimming any excess fat from the chicken breasts. Season them generously with salt and pepper.
Heat olive oil in a large skillet over medium-high heat. Quickly sear the chicken breasts on both sides until golden brown (about 2-3 minutes per side). This step is optional but adds a ton of flavor!
Transfer the seared chicken to your slow cooker.
In the same skillet, sauté the onions and garlic until fragrant and translucent (about 3-4 minutes). Add this to the slow cooker.
Pour the crushed tomatoes over the chicken and onion mixture. Add the dried oregano and red pepper flakes if using.
Cover and cook on low for 6-8 hours, or on high for 3-4 hours. The chicken is done when it reaches an internal temperature of 165°F (74°C).
About 30 minutes before serving, stir in the fresh basil leaves.
Notes
Pro tip: For the best flavor, opt for San Marzano tomatoes and free-range chicken. And don't skimp on the basil - fresh is best!
