If you've got chicken breasts and a bottle of Italian salad dressing on hand, then you're about 30 minutes away from a simple but surprisingly delicious entrée.
Place 4 large boneless, skinless chicken breasts on cutting board. Trim away any fat or unappealing spots and discard.
If needed, pound chicken breasts with meat pounder or rolling pin just until all 4 chicken breasts are mostly equal in size and thickness. Season chicken breasts on all sides with salt and freshly ground black pepper to taste. Set chicken side.
Pour half of 1 cup Italian dressing into bottom of 9x13 baking dish, covering bottom of dish as much as possible. Place chicken breasts on top of dressing in baking dish, laying chicken breasts side-by-side but without overlapping.
Pour remaining Italian dressing evenly over tops of chicken breasts. Flip chicken over 2 to 3 times to fully coat all sides of each chicken breast in dressing. When satisfied with coverage, reposition chicken breasts to lay side-by-side in baking dish without overlapping.
Cover baking dish tightly with plastic wrap, then place baking dish in refrigerator. Let chicken marinate in dressing at least 1 hour, and no more than 8 hours. Approximately halfway through desired marinating time, flip chicken breasts over once to allow both sides to marinate evenly.
To Cook the Chicken Breasts
Toward end of desired marinating time, preheat oven to 350° Fahrenheit. If needed, adjust oven racks so that baking dish will sit in center of oven. Remove baking dish from refrigerator, then remove and discard plastic wrap.
Place baking dish in preheated oven. Bake chicken, uncovered, 25 minutes. After 25 minutes, insert internal meat thermometer into 1 or 2 chicken breasts to check doneness. Continue baking as needed, checking temperature every 3 to 5 minutes, until chicken reaches 160° Fahrenheit internally.
Once internal temperature of chicken reaches 160° Fahrenheit, remove baking dish from oven and set dish aside. Let chicken rest 5 minutes.
After 5 minutes, transfer chicken to serving plates. Spoon Italian dressing from baking dish over tops of chicken, if desired. Sprinkle finely grated fresh parmesan over tops of chicken (optional) and serve immediately with small leafy side salad, angel hair pasta, quinoa, broccoli, or sides of choice.
Recipe Notes
Salt & Pepper: Be careful not to go too heavy with the salt and pepper on the chicken. Italian dressing typically contains salt, along with plenty of other spices, and you don't want to inadvertently overdo the seasonings!
Italian Dressing: If you like a really saucy chicken dish, you're welcome to use more than 1 cup of the Italian salad dressing.
Marinade: If you're short on time, you can cut the marinating time down to as little as 15 minutes. You can skip it entirely, but you'll get the least amount of Italian flavor that way.
Food Safety: The chicken will cook residually during the 5-minute rest period after it comes out of the oven. I tell you to take it out at 160° Fahrenheit to allow for that, so that the chicken shouldn't be over-cooked by the time you eat it. You want the chicken to reach 165° Fahrenheit internally before serving it, though, for food-safety purposes.
Make it Keto: Use an Italian dressing that doesn't contain any non-keto sugars or sugar substitutes.
Make it Whole30/Paleo: Use a compliant Italian dressing. Be sure to read the ingredients list! You can also make your own dressing (see below) to ensure it's compatible.
Nutrition Info: Your actual macronutrient breakdown will depend on the weight of the chicken breasts you use and the content of the Italian dressing you choose.
