Introduction

Italian Dressing Chicken is a simple, flavorful dish that combines tender chicken with a medley of colorful bell peppers and savory seasonings. Marinated in zesty Italian dressing, it’s perfect for an easy weeknight dinner that feels special without the fuss.

A white round plate holds a dish with two main layers. The bottom layer is a thick, creamy mashed potatoes with a slightly chunky texture and a pale off-white color, spread in a wide circular shape. The top layer is a crispy, golden-brown roasted chicken thigh, shiny with a glaze and topped with slivers of red, yellow, and green peppers, adding pops of color. Surrounding the mashed potatoes is a pool of orange-brown oily sauce with visible specks of black pepper and herbs that lightly coats the base of the plate.

Ingredients

6-8 pieces chicken
1/2 cup Italian dressing
1 small red bell pepper, sliced
1 small green bell pepper, sliced
1/2 small yellow onion, sliced
2 teaspoons paprika
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon Italian seasoning
1 teaspoon adobo seasoning
1 teaspoon salt (or more to taste)
3 tablespoons unsalted butter (optional)

Instructions

Step 1: In a large bowl, add the chicken pieces and pat them dry. Add the sliced red and green bell peppers and yellow onion. Pour the Italian dressing over the mixture along with paprika, garlic powder, onion powder, Italian seasoning, adobo, and salt. Mix well to coat everything evenly. Let it marinate for at least 1 hour or up to overnight in the refrigerator.
Step 2: Preheat your oven to 375°F (190°C). Place the marinated chicken and vegetables in a 13×9-inch baking dish. Sprinkle a little extra all-purpose seasoning if desired. Top the chicken with 3 tablespoons of sliced unsalted butter, if using, to add richness and moisture during baking.
Step 3: Bake uncovered on the middle rack for about 1 hour, or until the chicken is cooked through and the top is golden brown. Serve hot and enjoy!

Tips & Variations

For a spicier kick, add a pinch of red pepper flakes to the marinade.
Use boneless chicken thighs if you prefer a juicier result; adjust cooking time accordingly.
If you don’t have Italian dressing, mix olive oil, vinegar, garlic, and Italian herbs for a quick homemade version.
Adding sliced mushrooms or cherry tomatoes with the peppers can add extra flavor and color.

Storage

Store any leftover chicken and vegetables in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through. Avoid overcooking during reheating to keep the chicken tender.

FAQs

Can I use other types of chicken cuts for this recipe?

Yes, you can use boneless skinless chicken breasts or thighs. Just note that cooking times may vary slightly depending on the thickness and type of cut you use.

Is it necessary to marinate the chicken overnight?

Marinating overnight enhances the flavor, but if you’re short on time, even 1 hour of marinating will impart good taste to the chicken and vegetables.
