The story behind the recipe

A spoonful of chicken in cream sauce becomes something rather grand when it lands in a puff pastry shell. The filling is soft, with mushroom slices and little pieces of green pepper; the pastry gives it a crisp border. There is no roast to carve and no sauce to pass separately. Each shell holds its own small serving.

Wilson put it on toast

Mary A. Wilson's 1920 Mrs. Wilson's Cook Book includes Chicken a la King made with cooked chicken, mushrooms, green pepper and egg yolks. She serves it on toast. Our pastry shells change that base, but keep the pleasing contrast between a rich sauce and something baked beneath it.

A name with room for more than one recipe

Wilson's entry starts with a thick sauce already prepared and chicken breast cut into pieces. Mushrooms and pepper are parboiled, and lemon juice, mustard, salt and paprika join the sauce. It is quite a concise account of a dish with several components. The title alone won't tell you whether another version includes lemon, cream, pastry or toast.

There is no need to choose an elaborate origin legend to enjoy it. Wilson gives us a particular printed version from the decade, with enough detail to see both the family resemblance and the differences. A chicken dish can keep its familiar name while its sauce and serving base change considerably.

Here, butter, flour, milk and cream make the sauce from the beginning. We sauté the vegetables in butter instead of parboiling them, halve Wilson's cup of mushrooms and specify our own pepper and chicken quantities. We omit her lemon and mustard, leaving salt and sweet paprika for seasoning. Ready-made pastry shells and an off-heat pasteurized-yolk finish complete the adaptation.

The shell is part of the meal

Puff pastry makes the filling feel different from chicken ladled into a bowl. Its raised sides gather the sauce, and its outer edges give each forkful a chance to include a little crisp pastry. That contrast is best enjoyed soon after filling; the shells aren't intended to store the sauce.

Frozen shells also let you choose where to spend your effort. Follow their package for baking while you make the filling, rather than adding a separate pastry-making project to dinner. The estimate below assumes cooked chicken is already available. Starting with a raw bird is a different afternoon's work.

The mushrooms and green pepper keep the filling from being only chicken and cream. Mushroom slices have a softer bite, while pepper gives a fresh vegetable flavor. They remain visible in a pale sauce, with paprika providing a small warm accent rather than a strongly spiced finish.

What the yolks contribute

The yolks enrich the sauce at the end. This version calls for pasteurized yolks because they are stirred in off the heat, without a separate cooking stage. That ingredient choice belongs to the written method; Wilson's heated finish doesn't make ordinary raw yolks interchangeable here.

With the shells baked and the filling ready, assembly is brief. The satisfying part is how much the pastry changes the presentation of ingredients that were already cooked: a modest amount of chicken, vegetables and sauce becomes four distinct portions, each with golden pastry around it.

Instructions

Preparation

  1. Bake the pastry shells

    Bake the frozen puff pastry shells according to the package directions while you prepare the sauce.

The Sauce

  1. Cook mushrooms and pepper

    Melt the butter in a wide saucepan or a chafing dish. Add the sliced white mushrooms and diced green bell pepper and cook until softened.

  2. Stir in the flour

    Sprinkle the all-purpose flour over everything and stir it in until smooth.

  3. Add milk and cream

    Slowly pour in the whole milk and heavy cream, stirring until the sauce thickens.

  4. Heat the chicken in the sauce

    Add the cooked chicken, the salt, and a good pinch of sweet paprika. Let everything heat through completely.

  5. Add pasteurized yolks off the heat

    Just before serving, beat the pasteurized egg yolks lightly in a small bowl, then take the pan off the heat and stir them in. The yolks enrich the sauce. Do not return the pan to the heat.

  6. Fill the pastry shells

    Spoon the hot chicken mixture generously over the baked puff pastry shells and serve immediately.

Recipe notes

When adjusting quantities

Allow one pastry shell per serving. Keep the sauce method unchanged and check that a larger batch heats through before adding the yolks.

Original recipe notes
