Pat the chicken thighs dry with a paper towel and season them with salt, pepper, and paprika. Heat olive oil and butter in a large skillet over medium-high heat. Sear the chicken thighs, skin side down, for 5-7 minutes until golden brown. Flip and cook for another 5 minutes. Remove and set aside.
Cook the Aromatics
2
In the same skillet, add butter and olive oil. Sauté the onions for 2-3 minutes until softened. Add garlic and cook for 30 seconds until fragrant.
Cook the Mushrooms
3
Add the sliced mushrooms and thyme. Cook for 5-6 minutes, stirring occasionally, until mushrooms are golden and tender.
Prepare the Creamy Sauce
4
Pour in the chicken broth and let it simmer for 2 minutes to reduce slightly. Stir in the heavy cream, Parmesan cheese, and Dijon mustard. Add red pepper flakes if using, then let the sauce simmer for 2-3 minutes until it thickens.
Combine and Simmer
5
Return the chicken thighs to the skillet, skin side up. Reduce heat to medium-low, cover, and let simmer for 10 minutes or until the chicken is cooked through (internal temp 75°C / 165°F). Remove from heat and let it rest for 5 minutes.
Garnish and Serve
6
Sprinkle with fresh parsley. Serve hot with mashed potatoes, rice, or pasta.
Note
Storage: Store leftovers in an airtight container in the fridge for 3 days. Reheat gently on the stove.
Variations: Swap heavy cream for Greek yogurt for a lighter version.
Make it dairy-free: Use coconut milk instead of cream and skip the Parmesan.
Extra flavor: Add a splash of white wine after cooking the mushrooms.
