Cook the Bacon: In a large skillet over medium heat, cook the bacon until crispy. Remove with a slotted spoon and set aside, leaving the bacon fat in the pan.
Cook the Chicken: Season the chicken strips with salt, pepper, and paprika. Add olive oil and butter to the skillet with the bacon fat. Sear the chicken strips for about 3-4 minutes per side until golden brown. Remove and set aside.
Sauté the Mushrooms & Garlic: In the same pan, add the mushrooms and cook until they release their moisture and turn golden brown. Stir in the minced garlic and cook for another 30 seconds until fragrant.
Make the Sauce: Stir in the Dijon mustard, chicken broth, and heavy cream. Bring to a simmer, scraping up any browned bits from the pan.
Combine Everything: Return the chicken and bacon to the skillet. Let everything simmer for 5 minutes until the sauce thickens slightly and the chicken is cooked through.
Serve & Enjoy: Garnish with fresh parsley if desired. Serve over rice, pasta, mashed potatoes, or enjoy it as is!
