Ingredients
- 6 boneless, skinless chicken thighs, Use thighs for tender, juicy meat that stays moist during searing.
- Salt, to taste, Enhances all flavors; add gradually and adjust at the end.
- Black pepper, to taste, Freshly ground gives the best aroma and balanced heat.
- 1 tablespoon olive oil, For searing the chicken and preventing sticking.
- 2 tablespoons butter, Adds richness and helps build the sauce base.
- 1 small yellow onion, finely chopped, Sweet and savory base flavor when softened.
- 6 cloves garlic, minced, Provides the bold garlic aroma and taste throughout the sauce.
- 1/3 cup chicken broth, Used to deglaze the pan and add depth without heaviness.
- 1/2 cup cooked crispy bacon, diced, Brings salty crunch and smoky flavor to the creamy sauce.
- 1 cup heavy cream, Creates the rich, silky body of the sauce.
- 3/4 cup milk, Lightens the cream slightly while keeping sauce creamy.
- 1 tablespoon Italian seasoning, A blend of herbs that complements chicken and spinach.
- 1 teaspoon oregano, Adds a focused herbal note.
- A pinch crushed chili pepper flakes, Adds a subtle heat that lifts the creaminess.
- 3 cups baby spinach leaves, Wilts quickly and adds a fresh, leafy contrast.
- 1/2 cup grated Parmesan cheese, Melts into the sauce for nutty, savory depth.
- 1 tablespoon cornstarch, Used to thicken the sauce when mixed into a slurry.
- 1 tablespoon water, Combine with cornstarch to make a smooth slurry.
Step-by-Step Instructions
- Season the chicken thighs with salt and black pepper on both sides and let sit for a few minutes. This helps the seasoning penetrate and improves browning.
- Heat a large skillet over medium-high heat and add the olive oil. When the oil shimmers, sear the chicken thighs for 5 to 8 minutes per side until golden and cooked through. Use a meat thermometer to check for 165°F in the thickest part if unsure. Remove from the skillet and set aside on a plate.
- In the same skillet, melt the butter, then add the finely chopped onion and minced garlic; sauté for about 1 minute until fragrant. Cook just until the onion softens; do not let the garlic brown.
- Pour in the chicken broth to deglaze the pan and add the diced bacon; cook for 1 to 2 minutes. Scrape up any browned bits on the bottom of the pan for extra flavor.
- Whisk in the heavy cream and milk, then stir in the Italian seasoning, oregano, and crushed chili flakes. Adjust salt and pepper as needed. Bring the mixture to a gentle simmer to combine flavors.
- Fold in the baby spinach until wilted, then stir in the grated Parmesan cheese. Stir gently until the cheese melts and the spinach is evenly distributed.
- In a small bowl, mix the cornstarch with water to create a slurry, then add it to the skillet while stirring until the sauce thickens. Add the slurry slowly and allow a minute or two for the sauce to come together.
- Return the chicken to the skillet, spoon the sauce over it, and simmer briefly until heated through. Serve immediately with extra sauce spooned over the chicken.

FAQ
- Can I use chicken breasts instead of thighs?
Yes. Chicken breasts work fine; reduce searing time slightly and check for an internal temperature of 165°F to avoid overcooking. - How do I prevent the cream sauce from separating?
Simmer gently and avoid boiling. Add the cornstarch slurry if the sauce needs thickening to help stabilize the texture. - Can I skip the bacon?
Yes. The bacon adds smokiness and texture, but the sauce will still be flavorful without it. - Is this dish good for meal prep?
It can be prepared in advance and stored for up to 3 days in the refrigerator. Reheat gently to maintain sauce quality. - What should I serve with this dish?
Serve over rice, pasta, mashed potatoes, or with crusty bread to soak up the sauce.
People Also Ask
- How long should I sear boneless chicken thighs?
Sear boneless thighs 5 to 8 minutes per side over medium-high heat until golden and cooked through. - Can I use half-and-half instead of heavy cream?
Half-and-half is thinner and will produce a lighter sauce; it may need a bit more cornstarch to thicken. - When should I add spinach so it does not overcook?
Add spinach to the sauce after cream has been added and wilt it briefly until just softened. - How can I make the sauce thicker without cornstarch?
Simmer the sauce longer to reduce and concentrate, or stir in more grated Parmesan to thicken slightly. - Will the sauce taste different the next day?
Flavors often mellow and meld after resting, so the sauce may taste even more cohesive the next day. - Can I make this dairy-free?
This recipe uses heavy cream, milk, butter, and Parmesan, so it is not easily converted without substituting ingredients not listed.
