Notes on Quality
- Using boneless, skinless chicken thighs keeps the dish moist and flavorful, but you can also use chicken breasts for a leaner option
- Fire-roasted tomatoes add a smoky depth to the sauce, but regular diced tomatoes work too
- Fresh garlic enhances the flavor, but you can use garlic powder in a pinch
Possible Substitutions

- Use canned whole tomatoes and crush them by hand for a chunkier texture
- Try Italian seasoning instead of individual herbs for convenience
Step-by-Step Instructions
- Place chicken thighs in a bowl and season with salt and pepper. Dust chicken with flour, ensuring all sides are lightly coated
- Heat 1 tablespoon of oil in a large skillet over medium-high heat. Brown the chicken for about 4-5 minutes per side, then transfer to a plate
- In the same skillet, add the remaining tablespoon of oil and sauté the onions, bell pepper, and mushrooms for 5 minutes until softened and fragrant

- Pour the fire-roasted tomatoes, marinara sauce, and tomato paste into the slow cooker. Stir in the thyme, rosemary, oregano, basil, and minced garlic
- Add the chicken and sautéed vegetables to the slow cooker and toss gently to coat in the sauce
- Cover and cook on low for 6-8 hours or high for 3-4 hours until the chicken is tender
- Taste and adjust seasoning with additional salt and pepper if needed
- Serve over pasta, zucchini noodles, spaghetti squash, or rice. Garnish with Parmesan cheese if desired
Expert Tips & Tricks
