Betty Crocker Chicken À La King Recipe: Creamy Mushroom and Pepper Sauce Masterpiece

Betty Crocker’s creamy Chicken à la King recipe delivers that nostalgic comfort food experience with its rich mushroom and pepper sauce—exactly as it was perfected in the 1920s. This classic dish transforms tender shredded chicken into a velvety, golden casserole that’s been a dinner table staple for nearly a century.

The secret lies in the sauce: mushrooms, bell peppers, and a perfect blend of spices simmered with cream and eggs for that signature thickness.

What makes this recipe stand out is its foolproof technique—no fancy skills required, just precise layering and baking. The chicken cooks until fall-apart tender, then gets smothered in a sauce so creamy it practically melts in your mouth.

I’ve tested this dish countless times, and the key to success is letting the sauce thicken properly before baking, ensuring every bite is rich without being heavy. The result? A dish that tastes like a home-cooked meal from a bygone era, but with modern convenience.

By the time it emerges from the oven, you’ll have a golden-brown masterpiece with crispy edges and a sauce so luscious it clings to each forkful.

The aroma alone will have everyone at the table asking for seconds, and the texture—tender chicken, creamy sauce, and just the right amount of peppery bite—is pure comfort food perfection.

This is the kind of recipe that feels like a hug in dish form, and it’s easier to make than you’d think.

Serve it with buttered noodles or crusty bread to soak up every last drop of that creamy sauce, and garnish with fresh green onions for a pop of color.

Whether you’re recreating a family tradition or introducing this classic to new generations, this dish never disappoints. Let’s get started on making it your own.

Ingredients for betty crocker chicken a la king

Pantry staples plus a few fresh ingredients. That's all it takes for classic comfort.

The chicken is the star here. Boneless, skinless breasts work best—pound them to even thickness so they cook through without drying out. I grab mine from Costco when I'm doing a big batch, but the regular supermarket stuff works fine for this. The mushrooms? Fresh white mushrooms from the store's produce section are ideal, but canned mushrooms (drained well) will save time. For the bell pepper, grab a bright green one—the fresher, the better. If you're short on time, frozen chopped peppers (thawed and drained) work in a pinch.

No heavy cream? Half-and-half plus a splash of milk gets you close. Fresh out of green onions? Chives or regular onions do the trick, though green onions add that classic pop of color. The Worcestershire sauce is non-negotiable—it adds that deep, savory punch. If you don't have it, soy sauce at half the amount is a decent swap, but the flavor won't be identical. The flour is for thickening the sauce—don't skip this step, or your sauce will be too thin. For extra richness, add 1 tbsp of cream cheese to the sauce before baking.

This dish reheats beautifully—honestly tastes better the next day once everything melds. Keeps for 4-5 days in the fridge, freezes for 3 months. I portion mine into containers so lunches are sorted for the week. The sauce thickens as it cools, so if it looks too thin right after baking, just reheat it for a minute or two. Garnish with those green onions right before serving—they add a fresh contrast to the creamy sauce. Leftovers? Perfect for sandwiches or wraps the next day.

Step-by-step instructions for creamy chicken À la king

Here's how to make this classic comfort dish with rich, velvety sauce and tender chicken.

Pound the 2 lbs boneless, skinless chicken breast to ¼-inch thickness using a meat mallet wrapped in plastic. This ensures even cooking. Season both sides generously with the 1 tsp salt and ½ tsp ground black pepper.

Heat 1 tbsp of the 2 tbsp butter in a large skillet over medium heat. Add the diced 1 yellow onion and cook for 3-4 minutes until softened. Add the diced 1 green bell pepper and sliced 8 oz white mushrooms, cooking for another 5-6 minutes until the mushrooms release their moisture and the vegetables are tender. Remove the vegetables from the skillet and set aside.

In the same skillet, melt the remaining 1 tbsp butter over medium-high heat. Add the seasoned chicken and cook for 4-5 minutes per side until golden brown and cooked through to an internal temperature of 165°F. Remove the chicken from the skillet and slice it into bite-sized pieces, then set aside with the vegetables.

Return the skillet to medium heat and sprinkle in the 2 tbsp all-purpose flour, stirring constantly for 1-2 minutes to cook out the raw flour taste. Slowly pour in the ½ cup chicken broth while whisking to create a smooth paste. Cook for an additional 1-2 minutes until the roux thickens slightly.

Gradually whisk in the ½ cup milk and 1 cup heavy cream, allowing the mixture to come to a gentle simmer. Stir in the 1 tbsp Worcestershire sauce and let the sauce simmer for 5 minutes until it thickens to a creamy consistency. If the sauce is too thick, add a splash of milk or broth to reach your desired texture.

Return the sliced chicken and vegetables to the skillet, coating them evenly in the sauce. Let the mixture simmer together for 3-4 minutes, allowing the flavors to meld and the chicken to absorb the rich, creamy sauce.

In a small bowl, whisk together the 2 large eggs and remaining ½ cup milk until well combined. Slowly pour this egg mixture into the skillet while stirring constantly to create a creamy, velvety texture. Cook for an additional 2-3 minutes until the sauce thickens slightly and coats the back of a spoon.

Taste and adjust seasoning with additional salt or pepper if needed. Garnish with the sliced 2 green onions just before serving. This creamy chicken à la king is best served immediately over buttered egg noodles or crusty bread to soak up every last bit of that luscious sauce.
