- Butter: Unsalted, for a creamy base.
- Olive oil: Helps to brown the chicken perfectly.
- Yellow onion: Finely diced for a sweet, subtle flavor.
- Garlic: Minced, to add depth and aroma.
- All-purpose flour: Helps thicken the sauce (use gluten-free flour if needed).
- Chicken broth: Adds savory depth to the sauce.
- Heavy cream: For that irresistible creamy texture.
- Dijon mustard: A French touch that brings tanginess and complexity.
- Fresh thyme: Chopped; you can substitute with dried thyme if needed.
- Mushrooms: Sliced; optional but they add a wonderful earthy flavor.
- Frozen peas: For a pop of color and sweetness.
- Shredded cheese: Gruyère or mozzarella work wonderfully (optional).
- Salt and pepper: To season everything to perfection.
These ingredients work together to create a casserole that’s creamy, flavorful, and indulgent without being overly complicated. Plus, there’s plenty of room for substitutions—swap the peas for green beans or use coconut milk instead of heavy cream for a dairy-free option.
Equipment Needed
You don’t need anything fancy to make this recipe. Here’s what you’ll need:
- Large skillet: For browning the chicken and sautéing the vegetables.
- Whisk: To ensure the sauce is smooth and lump-free.
- Casserole dish: A medium-sized baking dish works perfectly.
- Cutting board and knife: For chopping vegetables and herbs.
- Mixing bowls: Optional, but helpful for preparing ingredients ahead of time.
If you don’t have a casserole dish, you can use a deep dish or even a cast-iron pan. Just make sure it’s oven-safe!
Preparation Method
- Preheat your oven: Set it to 375°F (190°C).
- Season the chicken: Sprinkle both sides with salt and pepper.
- Brown the chicken: Heat olive oil and butter in a large skillet over medium heat. Add the chicken and cook for 4-5 minutes per side until golden. Remove from the skillet and set aside.
- Sauté the onions and garlic: In the same skillet, add the diced onion and garlic. Cook until softened, about 3 minutes.
- Make the roux: Sprinkle the flour over the onions and stir well. Cook for 1 minute to remove the raw flour taste.
- Create the sauce: Gradually whisk in the chicken broth, followed by the heavy cream and Dijon mustard. Add the fresh thyme and stir until the sauce thickens (about 3-5 minutes).
- Add the vegetables: Stir in the mushrooms and frozen peas. Cook for 2 minutes to combine.
- Combine everything: Place the browned chicken in the casserole dish and pour the sauce mixture over the top. Sprinkle with shredded cheese if desired.
- Bake: Cover the casserole with foil and bake for 25 minutes. Remove the foil and bake for another 10 minutes, until bubbly and slightly golden.
- Rest and serve: Let the casserole rest for 5 minutes before serving. Enjoy!
Cooking Tips & Techniques
- Don’t rush the roux: Cooking the flour for a minute ensures your sauce won’t taste raw.
- Use fresh herbs: Fresh thyme gives a more aromatic flavor, but dried works in a pinch.
- Prevent soggy vegetables: If using fresh mushrooms, sauté them separately before adding to the sauce.
- Customize the cheese: Gruyère adds a nutty richness, but you can use cheddar, mozzarella, or skip it altogether.
- Keep the chicken moist: Cover the casserole for most of the baking time to prevent drying out.
Variations & Adaptations
- Low-carb option: Swap the all-purpose flour with almond flour and skip the peas.
- Vegetarian version: Replace the chicken with diced tofu or roasted cauliflower.
- Seasonal twist: Add asparagus or zucchini in the summer, and butternut squash in the fall.
- Dairy-free adaptation: Use coconut milk instead of heavy cream and dairy-free cheese.
One of my favorite personal variations is adding a splash of white wine to the sauce—it enhances the French-inspired flavors beautifully!
