A Quick Look at the Ingredients

Here’s a closer look at the key ingredients you’ll need and a few helpful notes to make sure your creamy caramelized onion chicken turns out rich, flavorful, and perfectly balanced.

• Chicken – Boneless chicken, such as chicken breast, cut into bite-sized pieces. It sears quickly, stays tender, and absorbs the creamy sauce beautifully.
• Onions – Slowly cooked until deeply golden and sweet. Proper caramelization adds incredible depth and natural sweetness to the sauce.
• Garlic – Adds warmth and savory flavor that balances the sweetness of the onions.
• Sun-dried tomatoes – Add a touch of richness and depth, balancing the creamy sauce with a slightly tangy flavor.
• Smoked paprika – Brings subtle smokiness and color without overpowering the dish.
• Heavy cream – Creates a rich, velvety sauce that coats every piece of chicken.
• Chicken broth – Loosens the sauce and adds extra savory flavor.
• Cream cheese – Helps thicken the sauce and gives it a smooth, creamy texture.
• Butter & olive oil – Used for searing the chicken and slowly caramelizing the onions for maximum flavor.
• Fresh parsley – Adds a touch of freshness and color right before serving.

How to Make Creamy Caramelized Onion Chicken Skillet

This skillet dinner is simple to make and comes together without much effort. A few small steps along the way help build rich, comforting flavor, resulting in a creamy sauce that tastes warm, satisfying, and homemade.

Season the chicken: Start by cutting the chicken breast into bite-sized pieces. Add the chicken to a bowl, season with salt, black pepper, smoked paprika, oregano, basil, and olive oil, and toss until well coated.

Sear until golden: Heat a skillet over high heat and melt in the butter. Add the chicken in an even layer and cook until golden on both sides. Once seared, remove the skillet from the heat and set it aside while you prepare the sauce.

Slowly caramelize the onions: Lower the heat to medium or medium-low and melt the butter in a second skillet. Add the chopped onion and cook slowly, stirring often, until the onions soften and turn deeply golden and sweet. This step takes a little patience, but it’s what gives the dish its rich, caramelized flavor.

Season the caramelized onions with salt, black pepper, and smoked paprika. Stir in the sun-dried tomatoes and garlic, then cook just until fragrant, keeping an eye on the garlic so it doesn’t burn.

Bring the sauce together: Pour in the chicken broth, then add the heavy cream and cream cheese. Stir gently until the sauce becomes smooth and creamy.

Finish the chicken: Return the chicken to the skillet along with any juices. Gently stir to coat everything in the sauce, then cover and let it simmer until the chicken is tender and cooked through.

Serve and enjoy: Finish with a sprinkle of fresh parsley and serve while warm. This creamy caramelized onion chicken is perfect with black rice, mashed potatoes, or pasta.

Tips

• Take your time with the onions. Cook them slowly over medium to medium-low heat until deeply golden and soft. This step builds natural sweetness and gives the sauce its rich, caramelized flavor.
• Don’t rush the sear. Let the chicken cook undisturbed so it develops a golden crust. This adds flavor and keeps the pieces juicy.
• Cut the chicken evenly. Bite-sized pieces cook quickly and evenly, preventing dry or overcooked spots.
• Whisk the sauce well. Stir the cream cheese into the broth and cream until fully smooth to avoid lumps.
• Adjust the thickness. If the sauce gets too thick, add a splash of chicken broth. If it’s too thin, let it simmer uncovered for a minute or two.
• Finish with fresh herbs. A sprinkle of fresh parsley brightens the rich, creamy flavors right before serving.

Variations

• Chicken thighs: Boneless, skinless thighs work great here and stay extra juicy. Just cut them into similar-sized pieces.
• No sun-dried tomatoes: You can leave them out for a milder, purely onion-forward sauce.
• Add mushrooms: Sauté sliced mushrooms with the onions for even more depth and a heartier sauce.
• Lighter option: Swap half of the heavy cream for extra chicken broth for a lighter, less rich sauce.
• Herb swap: Fresh thyme or a pinch of Italian seasoning works well if you’re out of oregano or basil.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. The sauce will thicken slightly as it chills, which is totally normal.

To reheat, warm gently on the stovetop over low heat or in the microwave, adding a small splash of chicken broth or cream to loosen the sauce if needed.

Can I make this ahead of time?
Yes. You can make it earlier in the day and gently reheat before serving. The flavors actually deepen as it sits.

Why did my sauce thicken so much?
Cream-based sauces naturally thicken as they cool. Just add a splash of broth or cream when reheating to loosen it back up.
