Slow Roasted Chicken w/ Baby Potatoes & Lemon Mustard Sauce


Many of us have bought a rotisserie chicken from the grocery store. While they are great when you are starving and want to put a meal on the table without any work, they can sometimes disappoint. Especially when the meat isn't juicy, it isn't pull off the bone tender, and it's flavor falls short of expectations. Did you know it is possible to create a rotisserie style at home? One having mouthwatering meltingly, tender, deeply flavorful meat that can be made in your own oven! I am here to tell you that you can! And here's the spoiler alert. The secret to creating the juiciest, most flavorful roasted chicken is a low and slow roasting time. 

Roasted for 3 hours (yes, three hours) at 300 degrees (F) is the key secret to making a roasted chicken far superior to any rotisserie chicken you can buy from your market. The secondary secret is rubbing the chicken with a butter and fresh herb mixture to add even more flavor to the juices as well as to the baby potatoes and garlic cloves roasting along with it. And yes, the potatoes and garlic cloves roast for 3 hours as well.


There are two ways of roasting the chicken. Place it breast side up and roast for 3 hours. Or place it breast side down, roast for 90 minutes, then turn it breast side up and continue roasting for another 90 minutes. In the first method, the skin has maximum exposure time to the heat and is more likely to get golden and crispy. In the second method, the breast meat retains its' moistness, yielding exceptionally juicy white meat. The downside is that the skin does not become as brown or crispy. So, you have to choose what matters most to you. A golden, crispy skinned chicken or one with incredibly succulent breast meat. I choose the later. Could I have increased the temperature to broil for 2 minutes before pulling the chicken out the oven to get a little more color? Yes, I could have. But I didn't. However, that is an option for you.


There are enough pan juices to make a gravy if you want. But why fuss if you don't have to. Besides the pan juices can be easily mopped up with some thick slices of a great bread. The Lemon Mustard Sauce is a great, very unexpected accompaniment to the roasted potatoes. The flavor of the chilled, creamy, tangy sauce served on the warm roasted potatoes creates a complex flavor profile that is certain to wow your palate! I highly recommend you serve it on the side and insist everyone at the table take a small spoonful to try before fully committing. I am willing to bet more than half of them will go in for larger spoonfuls! The addition of the sauce (served on the side) elevates a seemingly simple, rustic dinner to a whole other level. And turns an at home chicken dinner into something that feels more like a fine dining experience.

Paired with a great loaf of bread, a beautiful salad, and some wine (if you are wine lover) makes perfect weekend or Sunday afternoon dinner. This Slow Roasted Chicken w/ Baby Potatoes & Lemon Mustard Sauce is effortless and dinner party worthy! I wouldn't be surprised if it's one you decide is your signature dish, one you put on regular repeat. I also wouldn't be surprised if you never purchased a store-bought rotisserie chicken again. 

Recipe
Slow Roasted Chicken w/ Baby Potatoes & Lemon Mustard Sauce
Serves 4-5

Ingredients
1 (4 to 4 1/4 lb.) whole chicken (see notes)
2-3 pounds baby potatoes (see notes)
1 large head of garlic, cloves peeled
2 1/2 teaspoons Kosher salted, divided
4 Tablespoons unsalted butter, room temperature
2 Tablespoons chopped fresh herbs (thyme, rosemary, oregano)
1 teaspoon black pepper

3/4 cup mayonnaise
2 Tablespoons whole grain mustard
2 Tablespoons freshly squeezed lemon juice

Directions
1. Remove the chicken at least one hour before prepping for the oven.
2. In small bowl, mix together the butter, fresh herbs, 2 teaspoons Kosher salt and pepper. Blend well.
3. Preheat oven to 300 degrees (F).
4. Butter a 9"x13" baking pan. 
5. Add the potatoes and garlic cloves to the pan. Sprinkle with 1/2 teaspoon of salt.
6. Towel dry the chicken. Rub the butter/herb spread all over the chicken.
7. Place the chicken on top of the potatoes and herbs. Note: You can make a well by moving the potatoes around, so the chicken sits in comfortably.
8. Place the baking pan on a baking sheet and insert into the oven. Bake for 3 hours! Note: You can begin by placing the chicken breast side down and baking for 90 minutes. Then turn chicken breast side up and continue baking for another 90 minutes. If you use this method, the skin on the chicken will not get to a golden-brown color, but it will still be very delicious!!
9. Remove the chicken and potatoes and arrange on a serving platter along with all of the juices. Note: Stir the potatoes in the juices before transferring to a serving platter.
10. Mix together the mayonnaise, whole grain mustard and lemon juice. Serve with the chicken and potatoes. Note: Ideally, make the Lemon Mustard Sauce when you begin baking the chicken, so it has time for the flavors for blend. Once made, cover and keep chilled in the refrigerator.

Notes: (1) If you baby potatoes are more than 1 1/2" in diameter, cut in half. If smaller, keep whole. (2) I used an equal proportion of thyme, rosemary and oregano to create 2 Tablespoons. (3) If you live in the Midwest, look for Miller Chicken (they have small family farms in northern Indiana and southern Michigan). Their chicken is absolutely the best.
