Why Put Mustard on Chicken Before Grilling? The Secret to Juicy, Flavorful Results

Ever wondered why some grilled chicken tastes so much better than others? The answer might be sitting right in your refrigerator door Yellow mustard—yes, that simple condiment—could be the game-changer your grilling routine needs

I’ve been experimenting with different grilling techniques for years, and this mustard trick has consistently delivered some of the best results. Let’s dive into why putting mustard on chicken before grilling is a technique worth mastering.

The Magic Behind Mustard-Rubbed Chicken

When I first heard about slathering mustard on chicken before grilling, I was skeptical Would my chicken taste like a hot dog? Turns out, that’s not what happens at all Here’s why this technique works so well

1. Flavor Enhancement Without Overpowering

The most surprising thing about using mustard on grilled chicken is that the final product doesn’t actually taste strongly of mustard. Instead:

• The tanginess cuts through the richness of the chicken
• The acidity balances the savory flavors
• The spicy notes complement the natural taste of the meat
• The mustard mellows significantly during the cooking process

As Kathleen Purvis noted in her blog “I’ll Bite,” the mustard “keeps the chicken moist and adds plenty of flavor” without overwhelming the dish

2. Natural Tenderizer

Mustard isn’t just about flavor—it’s a functional ingredient too:

• Contains acetic and citric acids that break down proteins
• Helps tenderize the meat while it marinates
• Results in more succulent, tender chicken
• Works even with a short marination time (30+ minutes)

3. Creates the Perfect Crust

One of my favorite benefits of the mustard technique is the amazing texture it creates:

• The sugars in mustard promote caramelization
• Enhances the Maillard reaction (that delicious browning process)
• Forms a flavorful, slightly crispy exterior
• Develops deeper, more complex flavors than salt and pepper alone

4. Acts as a “Glue” for Seasonings

Ever been frustrated when all your spices fall off during grilling? Mustard solves that:

• Creates a sticky surface for seasonings to adhere to
• Prevents spices from burning off during cooking
• Ensures even distribution of flavors
• Allows better seasoning penetration

5. Moisture Retention

Dry chicken is the enemy of good grilling, and mustard helps combat this common problem:

• Forms a protective barrier that locks in juices
• Prevents excessive moisture loss during high-heat cooking
• Results in juicier final product
• Gives you more margin for error in cooking time

Which Mustard Works Best?

Not all mustards are created equal when it comes to grilling. Here are your options:

Yellow Mustard (American Mustard): The classic choice for many grillers. It’s mild, has good acidity, and creates a beautiful color. This is what French’s recommends in their Super Juicy Mustard-Rubbed Chicken recipe.

Dijon Mustard: Offers a more sophisticated, sharp flavor profile. Smoother texture and excellent for creating elegant chicken dishes.

Whole Grain Mustard: Provides texture and visual appeal with intact mustard seeds. Each seed creates little bursts of flavor.

Brown/Spicy Mustard: More intense heat and deeper flavor. Great if you want a more pronounced mustard character.

Honey Mustard: Adds a touch of sweetness that works beautifully with chicken. The sugars also help with caramelization.

For beginners, I recommend starting with basic yellow mustard. As one commenter named Chef Steph mentioned about using French’s yellow mustard: “It was the best grilled chicken I have ever eaten!”

How to Apply Mustard to Chicken for Grilling

The application process is simple but important to get right:

1. Start with clean, dry chicken pieces (works great with thighs, leg quarters, or whole cut-up chickens)
2. Apply a thin, even layer of mustard using your hands (preferred for control), a brush, or spoon
3. Don’t overdo it – you want coverage without globs of mustard
4. Season as desired – Montreal seasoning works great as mentioned in the original recipe, or create your own spice blend
5. Let it marinate for at least 30 minutes, but 2-4 hours (or overnight refrigerated) is even better

Beyond Basic Mustard: Recipe Adaptations

Once you’ve mastered the basic technique, there are countless ways to customize:
