Savory Chicken Stuffed with Mushrooms & Caramelized Onions
Ingredients
Equipment
Method
- Heat 1 tbsp butter and 1 tbsp olive oil in a large oven-safe skillet over medium-low heat. Add the thinly sliced yellow onion and cook slowly, stirring occasionally, for 15-20 minutes, or until deeply caramelized and soft. Remove onions from skillet and set aside in a mixing bowl.
- Increase heat to medium. Add the finely diced mushrooms to the same skillet (add a touch more oil if needed). Sauté for 5-7 minutes, stirring occasionally, until all the mushroom liquid has evaporated and they are nicely browned. Add the minced garlic and cook for another minute until fragrant. If desired, deglaze the pan with 1/4 cup dry white wine or chicken broth, scraping up any browned bits from the bottom.
- Add the cooked mushrooms and garlic to the bowl with the caramelized onions. Stir in the softened cream cheese, grated Parmesan cheese, chopped fresh parsley, and panko breadcrumbs (if using). Season with salt and black pepper to taste. Mix well to combine.
- Preheat your oven to 375°F (190°C).
- Place each chicken breast between two sheets of plastic wrap. Using a meat mallet or a rolling pin, pound each breast to an even 1/4 to 1/2-inch thickness. This creates a larger surface for stuffing and helps with even cooking.
- Drizzle the pounded chicken breasts with 1 tbsp olive oil and season generously on both sides with 1/2 tsp salt, 1/4 tsp black pepper, and 1/2 tsp paprika.
- Divide the mushroom and onion filling evenly among the chicken breasts. Place the filling on one end of each chicken breast. Roll each breast tightly, starting from the filled end. Secure the seam with toothpicks or tie with kitchen twine.
- Heat 1 tbsp olive oil in the same oven-safe skillet over medium-high heat. Once hot, carefully place the stuffed chicken breasts (seam-side down) into the skillet. Sear for 3-4 minutes per side until golden brown all over.
- Transfer the skillet with the seared chicken into the preheated oven. Bake for 20-25 minutes, or until the internal temperature of the chicken reaches 165°F (74°C).
- Remove the chicken from the oven and let it rest for 5-10 minutes before slicing. This allows the juices to redistribute, keeping the chicken moist. Remove toothpicks or twine before serving.
Notes
Pro Tips for Making This Chicken Stuffed with Mushrooms Onions
Through years of baking and cooking, I’ve gathered a few little secrets that truly elevate a dish, and this Chicken Stuffed with Mushrooms Onions is no exception. These tips will help you achieve that perfect balance of flavor and texture, making your kitchen adventures even sweeter and more rewarding.
For the most flavorful filling, take your time with the caramelized onions. Low and slow is the way to go, allowing them to transform into that deep, sweet, golden goodness. This patience truly pays off in every bite of this comforting dish, adding layers of rich flavor that can’t be rushed.
My Secret Trick: I always make sure to chill the filling for about 15-20 minutes before stuffing the chicken. This makes it much easier to handle, ensures it stays put inside the chicken breasts during cooking, and helps create a beautifully formed meal with no messy leaks.
Don’t overcrowd your pan when searing the chicken. Working in batches allows for a golden-brown crust, which locks in moisture and adds another layer of delicious flavor. A good sear is absolutely essential for that wonderful texture and even cooking, so give each piece its space.
Fun Variations for Chicken Stuffed with Mushrooms Onions
One of the greatest joys of home cooking is the freedom to play and adapt, making a recipe truly your own. Our delightful Chicken Stuffed with Mushrooms Onions is a fantastic canvas for your culinary creativity! Here are a few ways my friends and I love to tweak this comforting dish to suit different tastes or occasions:
Cheese Swaps
My friend Sarah always asks me to use a blend of provolone and mozzarella in the filling for an extra cheesy, melty experience. You could also try smoked gouda for a deeper, more complex flavor profile, or even a touch of goat cheese for a tangy surprise within your Chicken Stuffed with Mushrooms Onions. Each cheese brings its own personality!
Herb Adventures
Instead of just parsley, consider adding a touch of fresh thyme or rosemary to the mushroom and onion mixture. These woody herbs pair wonderfully with chicken and mushrooms, offering a delightful aromatic twist that can truly transform the dish. A pinch of sage is also lovely for a more autumnal feel.
Veggie Boost
For an added pop of color and nutrition, I sometimes fold in some finely chopped spinach or roasted red peppers into the filling. Just make sure to sauté the spinach first to remove excess moisture so your filling remains perfectly textured! Steamed and chopped asparagus tips would also be a delicious addition for a seasonal touch.
What to Serve With Chicken Stuffed with Mushrooms Onions
When you’ve put so much love into creating this wonderful Chicken Stuffed with Mushrooms Onions dish, choosing the right accompaniments truly completes the meal. I always think about what will complement its rich, savory flavors without overpowering them, ensuring a harmonious plate.
I love serving it alongside a simple, vibrant green salad with a light vinaigrette. The freshness and acidity of the salad cut through the richness beautifully, making each bite even more enjoyable and refreshing.
Another favorite pairing of mine is creamy mashed potatoes or a fluffy rice pilaf. They’re perfect for soaking up any extra creamy sauce from the chicken, making for a truly comforting plate that reminds me of Sunday dinners at home.
For a quick serving idea, a side of steamed asparagus or green beans with a squeeze of lemon and a sprinkle of sea salt is always a winner in my kitchen. Simple elegance that lets the main dish shine!
How to Store Chicken Stuffed with Mushrooms Onions
Ensuring your delicious Chicken Stuffed with Mushrooms Onions stays fresh and delightful for future enjoyment is wonderfully easy! With just a few simple steps, you can savor the flavors again without compromising on taste or texture, making meal prep a breeze.
Refrigeration
Leftover Chicken Stuffed with Mushrooms Onions should be stored in an airtight container in the refrigerator for up to 3-4 days. I always make sure it’s completely cooled before putting it away to prevent condensation, which can make things soggy.
Reheating
To reheat, gently warm the chicken in the oven at 300°F (150°C) until heated through, adding a splash of chicken broth or water to keep it moist and prevent it from drying out. A light dusting of fresh parsley after reheating brings it back to life beautifully, as if it was just made!
