Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

chicken thighs (bone-in, skin-on preferred)
olive oil
salt
black pepper
bacon, chopped
onion, diced
mushrooms, sliced
carrots, peeled and sliced
leek, sliced
all-purpose flour
dried thyme
bay leaf
chicken stock

Directions

Preheat your oven to 375°F (190°C).
Pat the chicken thighs dry with paper towels and season both sides with salt and black pepper.
Heat olive oil in a large oven-safe casserole dish or Dutch oven over medium-high heat. Place the chicken thighs skin-side down and sear until golden brown. Turn and brown the other side. Remove the chicken and set aside.
In the same pan, cook the chopped bacon until it begins to crisp and releases its fat.
Add the diced onion and sliced mushrooms to the pan. Cook until softened and lightly browned.
Stir in the sliced carrots and cook for a few minutes. Sprinkle the flour over the vegetables and stir well to coat everything evenly. Cook for another minute to remove the raw flour taste.
Add the dried thyme and bay leaf. Gradually pour in the chicken stock while stirring to create a smooth sauce. Bring the mixture to a gentle simmer.
Return the chicken thighs to the casserole, nestling them into the sauce.
Cover with a lid and transfer to the oven. Bake for about 45 minutes.
Remove the lid, add the sliced leek, and bake uncovered for an additional 15 minutes, or until the chicken is fully cooked and tender.
Remove from the oven, discard the bay leaf, adjust seasoning if needed, and let rest for a few minutes before serving.

Variations

For a creamier sauce, stir in a splash of heavy cream during the last 10 minutes of cooking.

You can swap carrots for parsnips or add diced potatoes to make it even heartier.

If you prefer a lighter version, use skinless chicken thighs and reduce the amount of bacon.

Fresh herbs such as rosemary or parsley can be added for extra aroma and freshness.

For a gluten-free option, replace the flour with cornstarch or a gluten-free thickener.

Storage/Reheating

Allow the casserole to cool completely before storing. Transfer leftovers to an airtight container and refrigerate for up to 4 days.

To freeze, place cooled portions in freezer-safe containers and store for up to 3 months. Thaw overnight in the refrigerator before reheating.

To reheat, warm in a 350°F (175°C) oven until heated through, or microwave individual portions in short intervals, stirring occasionally. Add a splash of chicken stock if the sauce has thickened too much.

FAQs

Can I use boneless chicken thighs instead of bone-in?

Yes, boneless thighs work well and may cook slightly faster. Keep an eye on them to prevent overcooking.

Can I substitute chicken breasts?

You can, but chicken breasts tend to be leaner and may become dry if overcooked. Adjust the cooking time accordingly.

How do I know when the chicken is fully cooked?

The internal temperature should reach 165°F (74°C). The meat should be tender and no longer pink near the bone.

Can I make this casserole ahead of time?

Yes, you can prepare it a day in advance and reheat before serving. The flavors often deepen overnight.

What can I serve with this casserole?

Mashed potatoes, rice, crusty bread, or steamed green vegetables pair beautifully with the rich sauce.

Can I leave out the bacon?

Yes, though the bacon adds smoky depth. You may want to add a little extra seasoning if omitting it.

Can I cook this entirely on the stovetop?

Yes, simmer gently with the lid on for about 45–60 minutes until the chicken is tender and fully cooked.

How can I thicken the sauce if it’s too thin?

Mix a small amount of cornstarch with cold water and stir it into the simmering sauce until it thickens.

Is this recipe suitable for freezing?

Yes, it freezes well. Store in airtight containers and thaw before reheating.

Can I add wine to the sauce?

Yes, a small splash of white wine added before the stock can enhance the flavor. Allow it to reduce slightly before adding the broth.
