Ingredients You’ll Need
Simple ingredients combine to make something special — rustic and comforting with a homemade feel.- Chicken thighs — 1 kg (bone-in, skin removed)
- Plain flour — 2 tbsp
- Butter — 25 g
- Olive oil — 1 tbsp
- Onions — 2, sliced
- Carrots — 2, chopped
- Celery sticks — 2, chopped
- Chicken stock — 600 ml
- Bay leaves — 2
- Fresh thyme — few sprigs
- Salt and black pepper — to taste
Step-by-Step Instructions
Each step brings you closer to that warm, cozy kitchen moment — tender chicken, creamy sauce, and vegetables simmered just right.
Step 1: Preheat the Oven
Preheat your oven to 350°F (180°C). This steady temperature gives the casserole its slow-baked tenderness and lets the flavors build naturally.
Step 2: Season and Coat the Chicke
Pat the chicken thighs dry, then season with salt and pepper. Lightly dust with flour to help them brown beautifully and thicken the sauce later.
Step 3: Brown the Chicken
In a large ovenproof casserole dish, heat butter and olive oil over medium heat. Add the chicken and sear until golden on both sides — about 5 minutes per side. Remove and set aside.
Step 4: Sauté the Vegetables
Add onions, carrots, and celery to the same pan. Sauté gently for 8 minutes until soft and fragrant, scraping up any golden bits from the bottom for flavor.
Step 5: Combine and Simmer
Return the chicken to the dish. Pour in chicken stock, add bay leaves and fresh thyme. Stir gently, then bring to a low simmer so everything starts mingling together.
Step 6: Bake Until Tender
Cover tightly with a lid and bake in the oven for 1 hour and 15 minutes. The chicken should be fork-tender, and the sauce will thicken into a rich, savory gravy.
Step 7: Season and Serve
Remove the bay leaves, taste and adjust seasoning, then serve piping hot. It pairs perfectly with mashed potatoes or crusty bread to soak up every drop of that golden sauce.
Each bite should taste rich and mellow, with fall-apart chicken and vegetables that melt together into a savory, comforting stew.
Pro Tips for Success
- Sear properly: Browning the chicken builds deep flavor in the sauce.
- Use fresh herbs: Thyme and bay add a soft aroma you can’t replace.
- Don’t rush: Slow baking allows the sauce to thicken naturally.
- Make ahead: It tastes even better the next day after the flavors deepen.

Can I use chicken breast instead of thighs?
Yes, but thighs stay juicier and more flavorful during long baking. If using breast, reduce cooking time slightly.

Absolutely. Brown the chicken first, then transfer all ingredients to a slow cooker and cook on low for 6 hours.
What vegetables go best in Chicken Casserole?
Carrots, celery, onions, and leeks are classic. You can also add mushrooms or parsnips for extra depth.
Can I freeze Chicken Casserole?
Yes — it freezes beautifully. Cool completely, store in portions, and thaw overnight before reheating.
