I learned how to make this French style roast chicken from my mother in law and boy did it blow my mind. The smell of this roast chicken wafting through the house is one thing but the taste? It’s incredible. I never knew that mustard could do that!

Aside from learning how to make this recipe, I’ll show you how to get a chicken baked to perfection with a juicy chicken breast and more:

Roast Chicken & Low FODMAP Diet

This low FODMAP roast chicken recipe is perfect for the holiday season or regular dinners. You can change it up and use turkey for a low FODMAP roast turkey instead. 

All you really need aside from the chicken is some butter, a handful of herbs and mustard. It’s incredibly easy and absolutely delicious. This section will cover the low FODMAP notes of each ingredient. Low FODMAP serving size information is all based on Monash University’s Low FODMAP App.

Butter Or Butter Substitutes

Butter is low FODMAP! It might seem weird because it’s a dairy product but butter is mostly fat and fats like oil have no FODMAPs. Butter is not lactose free. It has 1 gram of lactose per 100 grams or 3.5 ounces which is below the threshold according to Monash.

Butter is the base of the herb butter that we’ll use to stuff between the chicken breast and skin to seal in flavor and lock in moisture for a juicy breast. 

I used regular salter butter in this recipe but you can use vegan butter, margarine or ghee. Read up all about ghee and butter substitutes here:

Herbs

You can use fresh or dried herbs in the butter mix but I used a combination of fresh parsley with a mix of dried Italian herbs:

  • Parsley: Low FODMAP at 1 cup or 16 grams.
  • Oregano (dried): Serving size of 1 teaspoon or 3 grams. Larger portions of 85 grams or 3 ounces contain moderate amounts of sorbitol.
  • Thyme (dried): Low FODMAP at 1 cup or 16 grams.

Mustard (Yellow, Mild or Dijon)

The mustard is definitely the silent star of the show. It transforms the flavor of the chicken and is also low FODMAP. 

The FODMAP levels of mustard vary depending on the type of mustard you use but regular yellow mustard has a low FODMAP serve of 30 grams or 2 tablespoons. You can add maple syrup to this mustard mix and create a low FODMAP maple mustard chicken roast!

Roast chicken or turkey is the hallmark of any meal -holiday or not- and sometimes it can be tiring to figure out what’s low FODMAP or not. So, here are some straightforward answers about roast chicken and the low FODMAP diet.

Can You Eat Rotisserie Chicken On Low FODMAP diet?

For the most part, yes. Chicken, turkey or any kind of meat is a protein which has zero FODMAPs. But premade rotisserie chickens can have high FODMAP seasonings or rubs like garlic and onion powder. Take off the skin if you’re not sure.

Can You Eat Chicken On A Low FODMAP Diet?

Chicken is protein and like all proteins that means it’s FODMAP free. Beef, lamb, fish, eggs, pork and seafood are also included in this list.

Is Baked Chicken Okay For IBS?

Chicken is a protein and doesn’t have any FODMAPs. You can eat it according to your appetite without worrying about IBS triggers as long as you marinade it with low FODMAP ingredients. 

Enough talk about FODMAPs! Let’s get to making some low FODMAP roast chicken.

Special French Style Low FODMAP Roast Chicken

It’s as easy as ABC: Make a herby butter, stuff it in between the chicken breast and the skin, cover it in mustard and bake. We’re going to get our hands a little dirty here but the magic is all in the prep. 

The butter stuffed under the skin means you don’t have to worry about basting your bird every other minute. Chop all the herbs and add it to the softened butter and season it generously with salt. 

Pat the chicken dry and grab the piece of skin at the base of the chicken cavity. Gently push your finger between the skin and the breast meat to separate the skin from the chicken without tearing it. 

Carefully separate the chicken skin from the whole breast. You can use the back of a spoon or your fingers. I prefer using my fingers because I can control the pressure without worrying the skin will break.

We don’t want any holes in the skin because the butter will melt and the juices will leak out leaving you with dry chicken breast.

Once you’ve separated the skin from the breast meat, lift the skin up and spoon the butter in the space you’ve made between skin and the chicken breast. Press the skin down and slide the spoon out.

Repeat this step until you’ve used up the butter. Spread out the butter by pressing the down on the skin and voila!

This is optional but you can place a lemon in the chicken’s cavity. Finally, season the chicken skin with salt, coat it with mustard and drizzle it with garlic infused olive oil.

Bake A Chicken To Perfection With This Tip

The key to a perfect roast chicken? Timing: 

Every pound (500 grams) of chicken takes 30 minutes to cook at 356F (180C). My chicken was 1 pound and took an hour to cook fully.

Baking the bird according to weight and stuffing butter between the skin will make sure the breast stays nice and juicy while the rest of the bird cooks.

Another way to get the perfect roast is how long you bake it, covered and uncovered. First you want to cover the chicken with aluminum and bake it in the oven for half of the time. 

And then remove the aluminum and let it finish cooking for the remainder of the time. This will ensure a perfectly cooked chicken without burning the skin.

The perfect low FODMAP roasted chicken needs some killer sides, right?
