Why This Recipe Works

The mayonnaise creates a protective coating that helps the chicken stay moist while baking.

As the chicken cooks, the onion soup mix releases deep savory flavors that mimic slow-caramelized onions without requiring hours of cooking.

Garlic adds richness and aroma while helping create a flavorful crust.

The result is tender, juicy chicken with a golden exterior and incredible flavor in every bite.

Ingredients

For the Chicken

2½ pounds chicken breasts (bone-in or boneless)
¼ cup mayonnaise
2 tablespoons garlic, finely chopped
1 envelope (1 ounce) dry onion soup mix
Fresh parsley, chopped
Freshly cracked black pepper

Equipment

9x13 baking dish
Mixing bowl
Measuring spoons
Instant-read thermometer
Basting spoon

Instructions

Step 1: Prepare Oven

Preheat oven to 375°F (190°C).

Lightly grease a baking dish.

Step 2: Prepare Chicken

Pat chicken completely dry using paper towels.

Dry chicken browns better and develops a more flavorful crust.

Step 3: Make the Topping

In a small bowl combine:

Mayonnaise
Garlic
Onion soup mix

Mix until smooth.

Step 4: Coat the Chicken

Arrange chicken in the prepared baking dish.

Spread the mayonnaise mixture evenly over each piece.

Cover generously.

Step 5: Bake

For boneless chicken breasts:

Bake 35–40 minutes

For bone-in chicken breasts:

Bake 45–50 minutes

Cook until internal temperature reaches 165°F.

Step 6: Rest

Allow chicken to rest for 5 minutes before serving.

This keeps the juices inside the meat.

Step 7: Garnish

Sprinkle with:

Fresh parsley
Black pepper

Serve immediately.

Expert Tips

Use Fresh Garlic

Fresh garlic provides significantly more flavor than garlic powder.

Don't Skip Resting

Resting prevents moisture from escaping when sliced.

Check Temperature

Use a meat thermometer for perfectly cooked chicken.

Broil for Extra Color

Broil during the final 2–3 minutes for a deeper golden crust.

Variations

Cheesy French Onion Chicken

Add:

Swiss cheese
