French chicken casserole with bell peppers in a rustic casserole dish, ready to be served

French Chicken Casserole With Bell Peppers

An easy, rustic French comfort dish packed with flavor.
This French chicken casserole with bell peppers is a cozy, one-pot dish that’s rich in flavor and deeply satisfying. Inspired by rustic Provençal cooking, it features tender chicken thighs slowly simmered with bell peppers, garlic, herbs, and a splash of beer for a subtle malty depth. It’s a perfect chicken and bell pepper casserole for any time of the year.
In my Finnish kitchen, this recipe has become a seasonal favorite. The sweet bell peppers add vibrancy, while the beer enhances the sauce with earthy richness. The dish pairs beautifully with mashed potatoes or crusty bread for soaking up every drop of the savory tomato-based sauce.

Ingredients
  

  • 1 kg chicken thighs bone-in and skin-on for maximum flavor
  • 2 tbsp olive oil
  • 3-4 shallots finely chopped
  • 3 cloves of garlic minced
  • 2 tsp salt adjust to taste
  • 2 tsp freshly ground black pepper
  • 1 tbsp Herbes de Provence or a mix of thyme, rosemary, oregano, and marjoram (and a bit of lavender)
  • 1 can 400g preserved tomatoes (whole or chopped)
  • 1 yellow bell pepper sliced into strips
  • 1 red bell pepper sliced into strips
  • 1 green bell pepper sliced into strips
  • 1 can 330ml beer (a mild lager or pale ale works well)
  • A bunch of fresh flat-leaf parsley chopped, for garnish

Instructions
 

Prepare the Chicken

  • Place the chicken thighs in a large bowl and coat them evenly with olive oil, salt, and black pepper. Let them sit for a few minutes while you prepare the vegetables.

Brown the Chicken

  • Heat a large frying pan over medium-high heat. Once hot, add the chicken thighs, skin side down, and brown them for about 4-5 minutes per side until golden and crisp. This step adds extra depth to the flavor, so don’t rush it! Work in batches if necessary to avoid overcrowding the pan. Transfer the browned chicken to a casserole dish.

Sauté the Aromatics

  • In the same pan, add the chopped shallots and garlic. Sauté for 2-3 minutes until fragrant and slightly softened. Stir in the Herbes de Provence, letting them bloom in the warm oil for a moment.

Build the Sauce and cook the casserole

  • Pour the sautéed aromatics over the chicken in the casserole dish. Add the sliced bell peppers and the canned tomatoes with their juices. Stir gently to combine. Bring everything to a light boil, then lower the heat to a gentle simmer. Cover the casserole and let the chicken cook for 1 hour and 20 minutes, allowing the flavors to meld together.
  • After 1 hour and 20 minutes, pour in the beer. Stir lightly and let the casserole continue simmering, uncovered, for another 20 minutes. The alcohol will cook off, leaving behind a rich and slightly malty depth to the sauce.

Check for Doneness

  • Pierce the thickest part of a chicken thigh with a fork—if the juices run clear and the meat is tender, it’s ready. If not, let it simmer for a few more minutes.

Garnish & Serve

  • Chop a generous handful of fresh parsley and scatter it over the casserole just before serving.
  • Serve hot with:
Creamy mashed potatoes, Fluffy rice or Rustic bread rolls to soak up the sauce
