Common Mistakes to Avoid
When making Garlic Butter Chicken with Mushrooms, Peppers & Mashed Potatoes, it’s easy to make some common mistakes. Here are a few tips to help you avoid them.
Skipping the Marinade: Not marinating chicken results in less flavor. Marinate your chicken breasts with garlic powder, salt, and pepper for at least 15 minutes before cooking for a more flavorful dish.
Overcooking the Veggies: Overcooked vegetables can lose their texture and taste. Sauté your mushrooms, peppers, and onions just until they are tender to maintain their vibrant colors and crunch.
Underseasoning: Failing to properly season can lead to bland food. Be generous with salt and pepper in all components of the dish to enhance the flavors.
Incorrect Potato Preparation: Not boiling potatoes long enough can leave them lumpy. Ensure your potatoes are fork-tender before mashing for a smooth consistency.
Ignoring Garnish: Skipping fresh parsley as a garnish misses an opportunity for added flavor. Always add fresh herbs at the end for a burst of freshness.
