Betty Crocker’s Chicken à la King delivers the classic comfort of crispy celery crowns nestled in a velvety mushroom sauce that’s richer than restaurant versions. 💛 Growing up in Georgia, I first tasted this dish at my grandmother’s Sunday dinners—where crispy chicken and creamy sauce became a family tradition.

The secret lies in perfectly cooked chicken and a sauce that balances tangy cream with earthy mushrooms.

This recipe transforms simple ingredients into a dish that feels like a hug on a plate. You’ll start with chicken thighs or breasts, seared to golden perfection before being topped with celery crowns that stay crispy.

Ingredients for betty crocker chicken a la king

Simple ingredients that transform into a dish with crispy celery crowns and velvety mushroom sauce.

The chicken thighs are the backbone here—skin-on gives you that crispy edge when seared. Trader Joe's and Kroger usually have great deals on bone-in thighs, but boneless works too if you're short on time. For the celery crowns, grab the thickest stalks you can find (the ones with the biggest diameter)—they stay crispier. The mushrooms? Button or cremini work perfectly, but if you want to splurge, oyster mushrooms add a meaty texture. I always buy mine in bulk from Costco—cheaper and fresher than the grocery store.

No heavy cream? Half-and-half works in a pinch, though it won't be quite as rich. Running out of Dijon mustard? Yellow mustard at double the amount gets you close. The celery crowns are the star—flour them well, but don't skip the egg wash (or milk wash) or they'll turn out dry. For the sauce, if you're using pre-minced garlic, toast it in butter first—it makes a huge difference. And if you've got leftover chicken broth, use that instead of water for extra depth. The egg noodles? Any brand works, but Barilla or De Cecco hold up best when reheated.

This dish tastes even better the next day—honestly, the sauce gets richer as it sits. Store leftovers in the fridge for up to 4 days, or freeze for 3 months. I like to portion the sauce separately so I can reheat just what I need. The celery crowns? Eat them fresh or they'll get soggy. For serving, I always garnish with fresh parsley—it brightens up the whole plate. And if you've got extra sauce, drizzle it over mashed potatoes or toasted bread—it's that good.

Step-by-step instructions for Betty Crocker's chicken à la King recipe

Here's how to create classic crispy celery crowns and rich mushroom sauce—just like Betty Crocker's recipe.

Pat the 1.5 lb boneless chicken thighs completely dry with paper towels—this is non-negotiable for crispy skin. Season both sides generously with 1.5 tsp salt and 0.5 tsp ground black pepper. Let them sit at room temperature for 10 minutes while you prepare the pan.

Heat 2 tablespoons unsalted butter in a large skillet over medium-high heat until it foams. Add the chicken thighs and cook for 5-6 minutes per side until they develop a deep golden-brown crust. The reason we sear first is that this creates the signature crispy texture while locking in juices. If the pan isn't hot enough, the butter will burn before the chicken browns—watch carefully.

Once golden, transfer the chicken to a plate and tent loosely with foil to keep warm. Leave the rendered butter and browned bits in the pan—they're flavor gold for your sauce.

Trim the 3 whole celery stalks into 1-inch pieces, keeping the leaves for garnish. In a separate skillet, melt 1 tablespoon unsalted butter over medium heat. Add the celery and cook for 3-4 minutes until softened but not browned. Sprinkle with 1.5 tsp salt and 0.5 tsp ground black pepper, then remove from heat.

In the same skillet (don't wipe it clean), add 1 tablespoon unsalted butter and 2 tablespoons all-purpose flour to make a roux. Cook for 1-2 minutes until bubbly but not browned. This creates the perfect thickener for your sauce. Immediately add 0.5 cup chicken broth and whisk vigorously until smooth. The roux will transform into a velvety base for your sauce.

Add the 8 oz sliced fresh mushrooms and 1 whole diced yellow onion to the skillet. Cook for 5-6 minutes until the mushrooms release their moisture and the onions turn translucent. Stir in the 3 minced garlic cloves and cook for 30 seconds until fragrant—this is where all the magic happens.

Reduce heat to medium-low and pour in the 1 cup heavy cream. Stir in the 1 tbsp Dijon mustard—this adds that classic tangy depth. Let the sauce simmer gently for 3-4 minutes until it thickens slightly and coats the back of a spoon. Taste and adjust seasoning if needed, but trust your ingredients first.

Here's the thing—this is the moment that matters: return the seared chicken thighs to the skillet and spoon sauce over them. Let everything simmer together for 2-3 minutes to meld the flavors. The residual heat will finish cooking the chicken while infusing it with the creamy mushroom sauce.

While the chicken finishes, cook the 8 oz egg noodles according to package directions until al dente. Reserve 0.5 cup pasta water before draining—this starchy liquid is your secret weapon for adjusting sauce consistency later.

Divide the cooked egg noodles among four plates. Top each serving with 2 chicken thighs and ladle generous spoonfuls of the creamy mushroom sauce over them. The sauce should be thick enough to cling but still silky—if it's too thick, whisk in 1-2 tablespoons reserved pasta water until perfect.

Garnish each plate with the crispy celery crowns and a sprinkle of 0.25 cup chopped fresh parsley. The parsley adds freshness that cuts through the richness of the cream sauce. Serve immediately while the chicken is still warm and the celery crowns are crisp.

This dish delivers on all promises—crispy chicken thighs, creamy mushroom sauce, and that satisfying crunch from the celery crowns. The Dijon mustard gives it that classic tang, while the fresh parsley finishes it with brightness. You've just made restaurant-quality Chicken à La King!

Best sauces and condiments for betty crocker chicken a la king

Classic Cream Sauce Boosters

For extra richness, I always add a splash of 1 tbsp brandy or 2 tbsp sherry to the sauce while simmering—it deepens the flavor profile without overpowering. Let it reduce for 1 minute before finishing with the chicken. This little trick transforms the dish from good to exceptional. 💛

Tangy Mustard Variations

If you love heat, swap the Dijon mustard for ½ tsp hot sauce or 1 tsp honey mustard—both add complexity. For a sharper tang, mix 1 tsp apple cider vinegar into the cream before simmering. The acidity brightens the sauce beautifully.

Umami Enhancements

Boost the depth with 1 tsp fish sauce or 1 tbsp soy sauce stirred into the sauce before the cream. It’s a Southern secret that adds layers—trust me, it works.

I also love adding 1 tbsp miso paste for an umami punch, especially if you’re serving it with rice instead of noodles. 💫

Herb & Spice Infusions

Fresh herbs like thyme or rosemary make the sauce pop—add 1 tbsp chopped to the skillet with mushrooms. For a smoky twist, stir in ½ tsp smoked paprika with the garlic. A pinch of nutmeg (just ¼ tsp) adds warmth that pairs perfectly with the cream.

Cheese Elevations

Finish the sauce with ¼ cup grated Gruyère or Parmesan for a nutty, cheesy depth. Stir it in during the last 2 minutes of simmering—it melts beautifully into the cream.

For a creamy upgrade, fold in 2 oz cream cheese at the end; it thickens the sauce while keeping it velvety.
