Mr. Wonderful Chicken–lemon-garlic marinated chicken that is tender, juicy and full of flavor with hardly any effort! Make in the oven or slow cooker.

Mr. Wonderful Chicken
If you can remember to marinate the night before, this is one of those dinners that basically cooks itself! You just toss everything in a bag, let it sit and then dump it onto a pan or into the Crockpot. The ingredients are things I almost always have on hand. The chicken turns out tender, juicy, and perfectly seasoned every single time. This is a perfect “I’m too busy to cook” recipe. Greg and I loved it. Put it on your menu for this coming week! (Recipe adapted from Kevin ‘Mr. Wonderful’ O’Leary makes his perfect chicken recipe on Good Morning America).
Ingredients/Substitution Ideas
- Boneless skinless chicken thighs–you can also use bone-in chicken, chicken breasts
- Olive oil–or vegetable, canola
- Italian seasoning
- Kosher salt
- Black pepper
- Garlic powder–or minced garlic
- Onion
- Lemon zest and juice
Steps
Add all ingredients into a gallon ziploc bag and zip. Squish around so chicken is coated in oil and seasonings. Place in refrigerator for 8-24 hours.

Heat oven to 400° F. Dump the contents of the bag onto a baking sheet with edges. Bake for 22 minutes, or until internal temperature of chicken is 165°. (Thicker pieces might take longer and thin pieces will cook in a shorter time).

Serve and enjoy!

Notes/Tips
- Serve with mashed potatoes, rice pilaf or salad and garlic bread.
- This recipe is gluten free and dairy free and low carb.
- The longer the chicken marinates, the more flavorful it gets! Aim for at least 8 hours, but up to 24 is even better.
- You could toss in zucchini, bell peppers, or asparagus on the same sheet pan for an easy one-pan meal.
- Store leftovers in an airtight container* in the refrigerator for up to 4 days or in the freezer for up to 3 months.
- For a freezer meal buy fresh chicken at the store, throw in a ziploc with the other ingredients, freeze flat. Then when you’re ready to eat take the bag out of the freezer and place in the refrigerator for 24 hours to thaw. Bake and enjoy!
- Other recipes you can make with lemon zest are Instant Pot Chicken Julienne and Instant Pot Chicken Lemon Orzo Soup.

THANKS! On my way to marinate me some yard-bird! Yummmm!
Karen, would I need to pull the skin off if I use bone-in thighs?
No you can keep it on, it will crisp up. If you don’t like skin you can remove it if you want!
