Why You'll Love This Recipe
About the Ingredients
1.5 lbs (680g) boneless, skinless chicken breasts
Lean protein that stays moist and tender in the slow cooker. You can substitute with turkey breast or extra-firm tofu for a vegetarian option.
1 medium onion, diced
Adds a sweet, savory base. Use a yellow or sweet onion for milder flavor, or shallots for a more delicate taste.
3 cloves garlic, minced
Fresh garlic is best, but you can use 1 teaspoon of garlic powder in a pinch.
1 can (15 oz / 425g) diced tomatoes, undrained
Fire-roasted tomatoes add a smoky depth. If you have fresh tomatoes, chop 2 cups and add a splash of water.
1 cup (240ml) low-sodium chicken broth
Keeps the dish moist without adding excess salt. Vegetable broth works well too for a vegetarian version.
2 tablespoons tomato paste
Concentrates the tomato flavor. You can omit if you don't have it, but it really enhances the richness.
1 teaspoon dried oregano
Adds an earthy, Mediterranean note. Fresh oregano can be used, but add it in the last hour of cooking.
1 teaspoon ground cumin
Gives a warm, smoky flavor. Smoked paprika is a good substitute for a different twist.
1/2 teaspoon salt
Enhances all the flavors. Adjust to taste, especially if your broth is salted.
1/4 teaspoon black pepper
Adds a subtle kick. Freshly ground is best.
2 cups (300g) frozen mixed vegetables (peas, carrots, corn, green beans)
Adds color, fiber, and nutrients. Use any frozen blend you like, or fresh chopped vegetables like bell peppers and zucchini.
2 tablespoons chopped fresh parsley (optional, for garnish)
Brightens the dish with freshness. Cilantro also works well if you prefer.
Tips & Tricks
- Don't lift the lid! Every time you peek, you release heat and add 20 minutes to cooking time. Trust the process.
- If you prefer a thicker sauce, remove the chicken and vegetables, then mix 2 tablespoons cornstarch with 2 tablespoons cold water and stir into the liquid. Cook on high for 10 more minutes until thickened.
- To avoid mushy vegetables, add frozen veggies in the last 30 minutes of cooking. They will heat through perfectly without losing their texture.
Pro Tips
Step-by-Step Instructions
1. Prep the Chicken
Place the chicken breasts in the bottom of a 6-quart slow cooker. Season with salt and pepper. This allows the chicken to cook gently in the juices.
2. Add Aromatics
Scatter the diced onion and minced garlic over the chicken. The aromatics will infuse the meat with flavor as they cook.
3. Combine Saucy Ingredients
In a small bowl, mix the diced tomatoes, chicken broth, tomato paste, oregano, and cumin. Pour this mixture over the chicken, ensuring it's mostly covered.
4. Cook on Low
Cover and cook on LOW for 6-7 hours or on HIGH for 3-4 hours, until the chicken is tender and reaches an internal temperature of 165°F (74°C). The sauce will be bubbling gently around the edges.
5. Shred the Chicken
Carefully remove the chicken to a cutting board and shred with two forks. Return the shredded chicken to the slow cooker and stir.
6. Add Vegetables
Stir in the frozen mixed vegetables. Cover and cook on HIGH for an additional 30 minutes, until the vegetables are heated through but still crisp-tender.
7. Finish and Serve
Taste and adjust seasoning with salt and pepper. Serve hot, garnished with fresh parsley if desired. Enjoy over rice, quinoa, or on its own.
Delicious Variations
Mexican Twist
Add 1 teaspoon chili powder and 1/2 teaspoon smoked paprika, and stir in a can of drained black beans at the end.
Mediterranean Style
Swap oregano for basil and add 1/2 cup sliced Kalamata olives and 1/4 cup crumbled feta cheese just before serving.
Creamy Version
Stir in 1/2 cup plain Greek yogurt or light sour cream during the last 10 minutes of cooking for a creamy, tangy sauce.

Frequently Asked Questions

Yes, chicken thighs will work beautifully. They are more forgiving and stay moist even if cooked a bit longer. Just adjust cooking time slightly if needed.
Q: Can I put frozen chicken in the slow cooker?
It is not recommended for food safety reasons. Always thaw chicken in the refrigerator before slow cooking to ensure it reaches a safe temperature quickly.
Q: How can I thicken the sauce?
Mix 2 tablespoons cornstarch with 2 tablespoons cold water and stir into the sauce during the last 30 minutes of cooking. Cook until thickened.
Q: Can I make this recipe vegetarian?
Absolutely! Substitute the chicken with 1.5 lbs of extra-firm tofu, cubed, or 3 cups of cooked chickpeas. Use vegetable broth instead of chicken broth.
