Martha Stewart flat roast chicken is a whole bird opened up and roasted at high heat so the skin turns deep golden and crisp while the meat stays juicy. You get shatteringly crisp skin, tender white and dark meat, and a bright hit of lemon, garlic, and thyme in every bite. This version is inspired by Martha Stewart’s straightforward American home cooking, and it keeps the method simple enough to repeat often.

It takes about 70 minutes from start to finish, with only 25 minutes of hands-on work. The technique is easy once you’ve done it once, and it fits a weeknight dinner as comfortably as a weekend gathering or a holiday table.

Why This Martha Stewart Flat Roast Chicken Works

Flattening the bird is the whole trick. Cutting out the backbone and pressing the breastbone flat gives the chicken an even thickness, so the legs and breasts finish cooking at the same time instead of the breast drying out while the thighs catch up.

High heat does the rest. Roasting at 450°F (230°C) renders the fat fast and browns the skin before the meat overcooks, and setting the chicken directly on the vegetables means every drop of seasoned juice flavors the potatoes and onions underneath.

What You’ll Love About It

• Crisp Golden Skin — High heat and a dry bird give you shatteringly crisp skin.
• One Pan Total — Chicken and vegetables roast together on a single sheet pan.
• Fast Cooking Time — A flattened chicken roasts in well under an hour.
• Simple Pantry Flavors — Lemon, garlic, and thyme do all the work here.

Ingredients

This makes 4 servings, and the vegetables roast right alongside the chicken.

• 1 whole chicken (4 to 4 1/2 pounds / 1.8 to 2 kg) — giblets removed
• 2 tablespoons (30ml) olive oil
• 1 tablespoon (9g) kosher salt
• 1 teaspoon (2g) freshly ground black pepper
• 1 lemon — halved
• 4 garlic cloves — peeled and lightly smashed
• 6 fresh thyme sprigs
• 1 medium yellow onion — cut into 1/2-inch (1.3cm) wedges
• 1 pound (450g) small Yukon Gold potatoes — halved if large

Equipment

• Kitchen shears — sturdy ones for cutting along the backbone.
• Rimmed baking sheet — a half sheet pan gives the vegetables room to brown.
• Parchment paper or foil — for easier cleanup.
• Instant-read thermometer — the reliable way to check doneness.
• Carving board — with a channel to catch the juices.
• Sharp carving knife — for clean slices through the breast.

How to Make Martha Stewart Flat Roast Chicken

Step 1: Dry and Cut Out the Backbone

Pat the chicken completely dry inside and out with paper towels. Place it breast side down on a cutting board and use kitchen shears to cut along both sides of the backbone; discard it or save it for broth. Skipping the drying step is the common mistake here, because a wet bird steams in the oven instead of crisping.

Step 2: Flatten the Bird

Flip the chicken breast side up and press firmly on the breastbone with the heel of your hand until you hear it crack and the bird lies flat. Tuck the wing tips behind the breasts so they do not burn. The chicken should sit low and even against the board when you’re done.

Step 3: Season and Let It Sit

Rub the chicken all over with the 2 tablespoons (30ml) olive oil, then season evenly with the 1 tablespoon (9g) kosher salt and 1 teaspoon (2g) black pepper, working some under the skin of the breasts. Let it sit at room temperature for 20 minutes while the oven heats.

Step 4: Heat the Oven

Preheat the oven to 450°F (230°C) with a rack in the lower third. Line a rimmed baking sheet with parchment paper or foil for easier cleanup. Give the oven a full 15 to 20 minutes so it reaches temperature before the chicken goes in.

Step 5: Build the Pan

Scatter the onion wedges and potatoes on the prepared baking sheet and set the flattened chicken on top, skin side up, so the juices flavor the vegetables. Tuck the lemon halves, garlic cloves, and thyme sprigs underneath and around the chicken. Keep the pieces in a single layer so they brown rather than steam.

Step 6: Roast Until Golden

Roast for 35 to 45 minutes, until the skin is deep golden and crisp and a meat thermometer inserted into the thickest part of the thigh without touching bone registers 165°F (74°C). Rotate the pan halfway through if your oven browns unevenly. The potatoes should be fork-tender and the onions soft and browned at the edges.

Step 7: Rest the Chicken

Transfer the chicken to a carving board and let it rest for 10 minutes so the juices redistribute; if the potatoes are not yet tender, return them to the oven while the chicken rests. Don’t skip the rest, or the juices will run out and leave the meat dry.

Step 8: Carve and Serve

Carve the chicken by cutting the legs and thighs away from the body, then slicing the breast off the bone. Serve with the roasted potatoes and onions and spoon over any pan juices. A little of the soft roasted garlic mashed into the juices makes a quick sauce.

What to Serve With It

Keep the sides light so the crisp skin stays the focus. A green salad with a sharp lemon dressing, quickly sautéed green beans, or crusty bread for soaking up the pan juices all work well. Cold lemonade or sparkling water with lemon fits the bright flavors.

Tips for the Best Results

• Dry Thoroughly — Moisture is the enemy of crisp skin, so pat every corner.
• Room Temperature Bird — A short rest on the counter helps it cook more evenly.
• Watch the Wing Tips — Tuck them well or they will scorch at this heat.
• Use a Thermometer — Check the thigh, not the breast, for the truest reading.
• Don’t Crowd the Pan — Spread the vegetables out so they brown instead of steam.
• Save the Backbone — It makes a small pot of broth for later.

Easy Variations

• Smoky Paprika Rub — Add 1 teaspoon (2g) smoked paprika to the oil for a deeper color.
• Herb Switch — Swap the thyme for 4 rosemary sprigs or a small handful of parsley stems.
• More Vegetables — Add 2 carrots cut into 1-inch (2.5cm) pieces alongside the potatoes.
• Extra Lemon — Use 2 halved lemons, squeezing one over the pan juices at the end.

Storing and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. To freeze, pull the meat from the bones, pack it into freezer bags with a little pan juice, and freeze for up to 3 months; thaw overnight in the refrigerator. Reheat covered in a 350°F (175°C) oven for 15 to 20 minutes, until heated through to 165°F (74°C), adding a splash of chicken broth to keep the meat moist.

Nutrition (per serving)

These values are estimates per serving and will vary with the size of the bird and how much skin you eat.

FAQs

Can I prep this Martha Stewart flat roast chicken recipe ahead?

Yes, you can spatchcock and season the chicken up to 24 hours ahead and keep it uncovered in the refrigerator for even crispier skin. Let it sit at room temperature for 20 minutes before roasting so it cooks evenly.

What if I don’t have kitchen shears?

A sharp, heavy chef’s knife works, though shears give you more control along the backbone. Ask your butcher to remove the backbone for you if you’d rather skip that step entirely.

How do I know when the chicken is done?

The thigh should register 165°F (74°C) on an instant-read thermometer without touching bone. The juices at the leg joint should also run clear, not pink.

Where did flat roast chicken come from?

Spatchcocking, or butterflying, is an old technique used in many cooking traditions to cook poultry faster and more evenly over heat. It became popular in American home kitchens as a way to get crisp skin and juicy meat from a whole bird on a single pan.

Martha Stewart-Inspired Flat Roast Chicken

Print Recipe

This flat roast chicken is inspired by Martha Stewart’s classic American home cooking: a whole chicken is spatchcocked so the skin crisps deeply and the meat cooks evenly in well under an hour. Lemon, garlic, and thyme perfume the bird while the high heat renders the skin golden and shatteringly crisp. It is simple enough for a weeknight and handsome enough for company.
