Ingredients

14 oz (400 g) chicken breast, cut into thin strips
2 tablespoons (30 g) mustard, preferably Dijon or mild
¾ cup (200 ml) cooking cream (light cream or heavy cream works)
1 small onion, finely chopped
2 garlic cloves, minced
1 tablespoon (14 g) butter or olive oil
Salt and freshly ground black pepper, to taste
Fresh parsley, chopped, for garnish (optional)

Ingredient Notes

Choosing Dijon mustard adds a gentle tang and depth that complements the cream’s mildness — if you only have plain yellow mustard, it’ll work but expect a different flavor profile. Cooking cream or light cream is ideal here as it thickens the sauce smoothly without curdling; you can use heavy cream for an even richer dish. Fresh garlic and onion are the simple aromatics that build the sauce’s base flavor—don’t skip finely chopping these to ensure they melt into the sauce nicely.

Kitchen Tools Needed

Large non-stick or stainless steel skillet
Sharp knife and cutting board
Wooden spoon or spatula
Measuring spoons and cups

Step-by-Step Instructions

Heat the butter or oil in a large skillet over medium heat. Add the chicken strips, seasoning them with salt and pepper. Cook for 5-7 minutes, stirring occasionally, until they turn golden brown and are cooked through. Remove the chicken from the skillet and set aside.
Using the same skillet, add the finely chopped onion. Cook over medium heat for about 3 minutes, stirring often, until the onion softens and becomes translucent.
Add the minced garlic to the onion and cook for another minute, stirring to prevent burning and to release all the garlic’s flavor.
Lower the heat to medium-low. Stir in the mustard, mixing it with the onion and garlic so it evenly flavors the base. Then, slowly pour in the cooking cream, stirring constantly to combine.
Let the sauce simmer gently for 3-4 minutes, stirring frequently until it thickens slightly and becomes glossy. Keep an eye so it doesn’t boil rapidly, which can cause the cream to separate.
Return the cooked chicken strips to the skillet with the sauce. Stir gently to coat the chicken thoroughly in the mustard cream. Let it cook together for 2 more minutes so the flavors meld well.
Taste and adjust seasoning with salt and pepper if needed. Remove from heat.
Serve immediately, garnished with fresh chopped parsley if desired.

Pro Tips

Cut chicken into uniform thin strips so they cook evenly and quickly.
Use medium heat to avoid drying out the chicken while allowing it to brown nicely.
Stir the sauce constantly when adding the cream to prevent curdling or sticking.
For an extra touch, add a splash of white wine or a teaspoon of lemon juice when adding the cream for brightness.
If the sauce gets too thick, loosen it with a bit of water, chicken broth, or more cream.

Common Mistakes

Cooking chicken on too high heat, which can dry it out before it browns.
Adding cream to high heat without stirring can make the sauce separate.
Under-seasoning the sauce—mustard needs a bit of salt to balance the tang.
Overcooking garlic with the onion, leading to bitterness. Add it later and cook briefly.
Not letting the sauce simmer enough, leaving it too thin or underdeveloped in flavor.

Variations

Swap chicken strips for turkey or pork tenderloin sliced thinly to change the protein.
Add mushrooms or spinach to the sauce for a veggie boost.
Stir some grated Parmesan or sharp cheddar into the sauce for extra richness.
Include a teaspoon of smoked paprika or dried herbs like thyme for a different twist.

Serving Suggestions

This creamy mustard chicken pairs beautifully with plain steamed rice, buttery mashed potatoes, or even buttered egg noodles. A simple green salad or steamed vegetables complete the meal without overpowering the delicate sauce.

Storage Instructions

Store leftovers in an airtight container in the refrigerator for up to 3 days. The sauce will thicken as it chills, so you might need to loosen it with a splash of cream or milk when reheating.

Reheating Tips

Gently reheat the dish on low heat in a skillet or microwave, stirring occasionally. Avoid overheating to prevent the cream from separating and the chicken from drying out.

Frequently Asked Questions

Can I use chicken thighs instead of breast?
Yes, chicken thighs will add more flavor and stay juicy, but keep in mind they may take a bit longer to cook.

What can I substitute for cooking cream?
Heavy cream, half-and-half, or even full-fat coconut milk can work but will alter the flavor and texture slightly.

Is Dijon mustard necessary?
Dijon is recommended for its smooth flavor, but mild yellow mustard can be used; just expect a sharper taste.

Can I prepare this ahead of time?
You can cook the chicken and sauce separately, then combine and gently warm before serving to prevent overcooking.

How can I thicken the sauce if it seems too runny?
Let it simmer a bit longer on low heat or add a small slurry of cornstarch mixed with cold water.
