Directions

Prepare the slow cooker by lightly greasing the bottom or using a liner for easier cleanup.
Place the chicken breast fillets at the bottom of the slow cooker. Season them lightly with salt and pepper.
Add the quartered potatoes, baby carrots, and green beans on top of the chicken, spreading them evenly.
In a small bowl, mix melted butter, lemon juice, dried oregano, onion powder, crushed garlic, salt, and pepper until well combined.
Pour the seasoning mixture evenly over the chicken and vegetables, making sure everything is coated.
Cover the slow cooker with the lid.
Cook on high for about 4 hours or on low for about 7 to 8 hours, until the chicken is fully cooked and tender and the vegetables are soft.
For firmer green beans, add them during the last 1 to 2 hours of cooking instead of at the beginning.
Once done, gently stir everything to distribute the juices before serving.

Variations

You can customize this dish in many ways. Swap chicken breasts for chicken thighs if you prefer a richer taste. Add sliced zucchini or bell peppers for extra vegetables and color. If you want a stronger citrus flavor, add a little lemon zest along with the juice.

For a creamier version, stir in a small amount of cream or a spoon of sour cream at the end of cooking. You can also replace green beans with broccoli or peas depending on what you have available.

Storage/Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. Make sure the food has cooled completely before sealing.

To reheat, place a portion in the microwave for 1 to 2 minutes or warm it in a pan over low heat with a splash of water or broth to keep it moist. You can also reheat it in the oven at a low temperature until warmed through.

This dish can also be frozen for up to 2 months. Thaw in the refrigerator overnight before reheating.
