Sour Cream Onion Chicken

The smell of onions and sour cream baking together always pulls me back to my first apartment kitchen. I was trying to impress a new friend with something that sounded fancy but actually came together in minutes. The kitchen was tiny, the oven ancient, but when that dish came out bubbling and golden, I felt like I'd discovered a secret weapon for weeknight dinners.

My sister called me last winter complaining that her family was in a chicken rut. I walked her through this recipe over the phone, and she texted me later saying her kids had actually asked for seconds. Something about the familiar sour cream and onion flavor combination just works with everyone.

Ingredients

• 4 boneless skinless chicken breasts: Look for ones that are roughly the same thickness so they cook evenly. I've learned that pounding them slightly if they're uneven makes a huge difference.
• 1 teaspoon kosher salt: This basic seasoning is what makes the chicken taste like itself, just better.
• ½ teaspoon freshly ground black pepper: Freshly cracked gives you those little bursts of spice throughout.
• 1 cup sour cream: Full fat creates the richest sauce. I've tried low fat and it's fine, but why skimp on the good stuff here.
• ½ cup mayonnaise: This might seem unusual but it adds incredible depth and helps the sauce cling to every bite.
• ½ cup finely chopped green onions: The fresh onion flavor balances the dried soup mix beautifully.
• 1 packet dry onion soup mix: The shortcut that makes everything taste like comfort food in a bowl.
• 2 teaspoons garlic powder: Dont skip this even with onion soup mix. It adds that savory background note.
• 1 teaspoon onion powder: Extra insurance that you'll get that deep onion flavor we're chasing.
• 2 tablespoons milk: Just enough to loosen the sauce so it spreads easily over the chicken.
• ½ cup shredded cheddar cheese: Creates that gorgeous golden top that makes everyone's eyes light up.
• ½ cup crushed gluten-free crackers or potato chips: The optional crunch that takes this from good to I need this recipe now.

Instructions

Get your oven ready:

Preheat to 375°F and give your 9x13 baking dish a quick coating of oil or cooking spray. This little step saves you from stuck on mess later.

Prep the chicken:

Pat those breasts dry with paper towels, then sprinkle with salt and pepper on both sides. Lay them in the dish like they're settling in for a nap.

Whisk up the magic sauce:

In a medium bowl, dump in the sour cream, mayonnaise, green onions, soup mix, garlic powder, onion powder, and milk. Stir until it's smooth and smells like heaven.

Coat everything:

Spoon that creamy mixture over each chicken breast, spreading it thick so no chicken shows through. This is what keeps everything tender and flavorful.

Add the toppings:

Sprinkle the cheddar cheese across the top, followed by the crushed crackers if you're going for that extra crunch.

Bake until bubbly:

Slide it into the oven for 25 to 30 minutes. You'll know it's done when the sauce is bubbling up the sides and a thermometer reads 165°F when inserted into the thickest part.

The waiting game:

Let it rest for 5 minutes before serving. This gives the juices time to redistribute so they don't run all over your plate. Scatter extra green onions on top like confetti.

This recipe became our go-to when my husband started a new job and needed something comforting to come home to. There's something about the way the house smells when it's baking that just says everything's going to be okay.

Making It Your Own

I've played around with this base recipe so many times. Sometimes I swap in Greek yogurt for the sour cream when I'm trying to be virtuous, and honestly, no one notices the difference. The sauce still tastes rich and tangy, just with slightly less guilt involved.

Side Dish Magic

That creamy sauce practically begs to be spooned over something. I usually make extra rice or mashed potatoes because my family fights over who gets to scrape the baking dish. Steamed broccoli or green beans cut through the richness perfectly.

Make Ahead Wisdom

You can assemble the entire thing up to a day ahead and keep it covered in the fridge. The chicken actually gets more flavorful as it sits in that sauce. Just add a few extra minutes to the baking time since it'll be cold going into the oven.

• Don't add the cracker topping until right before baking or they'll get soggy
• Leftovers reheat surprisingly well in the microwave with a splash of water
• The sauce separates slightly when reheating but stir it back together and you're golden
