Sour Cream Onion Chicken

The way my grandmother's kitchen smelled when she pulled this chicken from the oven still lives in my memory. That tangy, savory creaminess mixed with caramelized onion notes somehow made even rainy Tuesday evenings feel special. I've recreated this dish countless times since then, and it never fails to bring that same comforting warmth to the table.

My husband initially turned up his nose at the idea of soup mix in a recipe. One bite changed his entire perspective, and now he requests this at least twice a month. I love watching people's expressions shift from skeptical to absolutely delighted when that first creamy, cheesy bite hits their tongue.

Ingredients

• 4 boneless, skinless chicken breasts: These cook evenly and stay tender under the creamy sauce, though thighs work beautifully if you prefer dark meat
• 1 teaspoon kosher salt: Essential for seasoning the chicken before the sauce goes on, creating layers of flavor
• ½ teaspoon freshly ground black pepper: Adds a subtle heat that balances the richness of the cream sauce
• 1 cup sour cream: The backbone of the sauce, providing tang and incredible moisture
• ½ cup mayonnaise: Adds body and helps the sauce cling to the chicken while baking
• ½ cup finely chopped green onions: Fresh onion flavor that brightens the entire dish, plus extra for garnish
• 1 packet dry onion soup mix: The secret weapon for deep, savory onion flavor in every bite
• 2 teaspoons garlic powder: Rounds out the flavor profile with aromatic warmth
• 1 teaspoon onion powder: Reinforces the onion notes without adding extra prep time
• 2 tablespoons milk: Thins the sauce just enough so it spreads evenly over the chicken
• ½ cup shredded cheddar cheese: Creates that golden, bubbly top that makes this dish so irresistible
• ½ cup crushed gluten-free crackers or potato chips: Optional but adds the most satisfying crunchy texture contrast

Instructions

Get your oven ready:

Preheat to 375°F and grease a 9x13 baking dish with a little butter or oil

Season the chicken:

Pat each breast dry with paper towels, then sprinkle both sides generously with salt and pepper

Make the magic sauce:

Whisk together sour cream, mayonnaise, green onions, soup mix, garlic powder, onion powder, and milk until completely smooth

Coat the chicken:

Spread that luscious sour cream mixture evenly over each piece, covering every corner

Add the toppings:

Sprinkle cheddar cheese across the top, followed by crushed crackers if you want that extra crunch

Bake until bubbly:

Slide into the oven for 25 to 30 minutes, until chicken reaches 165°F and the sauce is golden and bubbling

Rest and garnish:

Let the chicken sit for 5 minutes to lock in juices, then scatter extra green onions on top

This recipe became my go-to for new parents and friends recovering from surgery. Something about that creamy, familiar comfort food just says "I care" better than words ever could.

Making It Lighter

I've made this with Greek yogurt instead of sour cream and light mayonnaise, and honestly, nobody noticed the difference. The texture remains velvety and the flavor stays just as satisfying, making it perfect for lighter weeknight meals.

Perfect Pairings

The first time I served this with roasted broccoli and garlic mashed potatoes, my plate looked like a restaurant meal. Something about the bright green vegetables and creamy potatoes against that golden chicken creates the most inviting dinner table presentation.

Make It Your Own

Don't be afraid to play with the crunch factor. Sometimes I use fried onions instead of crackers, or add a pinch of smoked paprika to the sauce for depth. The base recipe is so forgiving that it welcomes experimentation beautifully.

• Try swapping in chicken thighs for even more juicy flavor
• Add fresh herbs like parsley or chives to the garnish for color
• Double the sauce recipe if you want extra for serving on the side
