My Mother-in-Law Clipped This Recipe From a Magazine in 1971 — We Still Make It Every August


Step 5: Add the Garlic

Once the onions are soft and golden, add the minced garlic.

Cook for approximately 30 to 60 seconds.

Don’t cook the garlic for too long at high heat because it can become bitter.

At this point, your kitchen should already smell wonderful.

The combination of browned chicken, butter, onions, garlic, and herbs creates the foundation of the entire dish.


Step 6: Make the Gravy

Sprinkle the flour over the onions.

Stir continuously for about one minute.

The flour helps thicken the sauce.

Slowly pour in the chicken broth while stirring.

Add the Worcestershire sauce and Dijon mustard.

Continue stirring until the sauce becomes smooth.

Add the thyme and black pepper.

If you like a slightly richer color and deeper flavor, you can add a small amount of smoked paprika.

The sauce should be flavorful but not excessively thick at this stage.

It will continue thickening as the chicken cooks.


Step 7: Return the Chicken to the Pan

Place the browned chicken thighs back into the skillet.

Arrange them among the onions.

If the chicken has released juices onto the plate, pour those juices back into the pan as well.

Bring the liquid to a gentle simmer.

Then reduce the heat to low.

Cover the skillet with a lid.

Allow the chicken to cook gently for approximately 25 to 35 minutes, depending on the size of the pieces.

The chicken should reach a safe internal temperature of 165°F (74°C) at the thickest part.

Don’t rely only on cooking time.

A food thermometer is the most reliable way to determine whether chicken is safely cooked.


Step 8: Let the Sauce Develop

This is where the old-fashioned character of the dish really comes together.

As the chicken cooks, its juices combine with the onions and broth.

The onions become incredibly soft.

The sauce becomes darker and richer.

The chicken absorbs the flavors surrounding it.

If the sauce becomes too thick, add a small amount of broth or water.

If it’s too thin, remove the lid during the final few minutes of cooking and allow some liquid to evaporate.

Taste the sauce before serving.

Add additional salt or pepper only if needed.


Step 9: Rest Before Serving

Once the chicken is fully cooked, turn off the heat.

Let the dish rest for approximately five minutes.

This gives the juices time to settle and allows the sauce to thicken slightly.

Sprinkle fresh parsley over the top if desired.

The finished dish should look similar to the photograph: golden-brown chicken surrounded by soft onions and a glossy, savory sauce.


What Makes This Recipe So Good?

The beauty of this dish comes from layering flavor rather than using dozens of ingredients.

First, the chicken is browned.

That creates a deep roasted flavor.

Then the onions cook in the same pan.

They absorb the flavorful browned bits left behind by the chicken.

Garlic adds another layer.

Chicken broth turns everything into a sauce.

Finally, the chicken cooks slowly in that sauce until tender.

Nothing complicated is required.

It’s simply good cooking technique.


The Best Onions to Use

Yellow onions are an excellent choice.

They become sweet and tender when slowly cooked.

White onions can also be used and tend to have a sharper flavor.

Sweet onions work particularly well if you enjoy a sweeter sauce.

You can even combine different varieties.

The important thing is to slice them relatively evenly so they cook at approximately the same rate.
