Why You’ll Love This Air Fryer Chicken Breast

• Fast but flavorful – Just a short marinade and under 20 minutes in the air fryer.
• Juicy inside, golden outside – The air fryer locks in moisture and creates a light crust.
• Bold and tangy – Whole grain mustard brings texture and zing.
• Low-effort, high-reward – No breading, no flour, no mess.
• Versatile – Serve it sliced over salad, tucked in sandwiches, or alongside roasted veggies.

Ingredients (And a Few Helpful Notes)

• 2 boneless, skinless chicken breasts – Medium-sized (about 6–8 oz each). Pound slightly for even cooking if they’re thick.
• 2 tablespoons whole grain mustard – This is the star. Look for one with a bold flavor and visible mustard seeds.
• 1 tablespoon Dijon mustard – Adds smooth heat and blends the flavors.
• 1 tablespoon olive oil – Helps the mustard cling and adds moisture.
• 2 garlic cloves, minced – Fresh is best, but ½ teaspoon garlic powder works too.
• 1 teaspoon smoked paprika – Optional, but adds depth.
• ½ teaspoon salt & ¼ teaspoon black pepper

Optional for garnish:

Chopped parsley or a squeeze of lemon juice for brightness right before serving.

Substitutions & Variations

• No whole grain mustard? Use all Dijon, but the texture will be smoother.
• Don’t eat garlic? A touch of onion powder still adds savoriness.
• Spice it up – Add red pepper flakes or a bit of cayenne if you like heat.
• Want it sweeter? A tiny drizzle of honey in the marinade balances the tang.

How to Make It: Step-by-Step

1. Mix the marinade.
In a small bowl, whisk together the whole grain mustard, Dijon mustard, olive oil, garlic, paprika, salt, and pepper.

2. Coat the chicken.
Pat the chicken breasts dry. Rub the mustard mixture all over both sides. If you have 15–30 minutes, let it sit and marinate — it gets even better.

3. Preheat the air fryer.
Set it to 375°F (190°C) for about 3 minutes so it’s hot and ready.

4. Cook.
Place chicken in the air fryer basket (don’t overcrowd) and cook for 16–18 minutes, flipping halfway. Internal temp should hit 165°F.

5. Rest and slice.
Let it rest for 5 minutes before slicing. This keeps it juicy!

Expert Tips for Juicy Chicken in the Air Fryer

• Don’t skip the rest time – That little pause before slicing makes a big difference.
• Pound thick chicken breasts slightly so they cook evenly.
• Use a meat thermometer – Especially with lean chicken, it’s the best way to avoid drying it out.
• Don’t overcrowd the basket – Give the chicken a little breathing room for that golden crust.

What to Serve with It

This chicken goes with practically anything. Here are a few easy ideas:

• Roasted sweet potatoes or baby potatoes
• Steamed green beans or asparagus
• Mixed greens with a simple vinaigrette
• Rice pilaf or couscous
• Crusty bread and a side of pickles (try it sandwich-style!)

Storing & Reheating Leftovers

Freezer: Yes, you can freeze it! Wrap tightly and freeze for up to 2 months. Thaw overnight before reheating.

Fridge: Store in an airtight container for up to 4 days.

Reheat: Gently warm in the air fryer at 350°F for 3–5 minutes, or microwave with a splash of broth or water to keep it moist.
