Ingredients

  

• Chicken: 4–6 boneless, skinless chicken thighs or 3–4 boneless, skinless breasts
• Mushrooms: 16 ounces cremini or button mushrooms, sliced
• Onion: 1 small yellow onion, finely chopped
• Garlic: 3–4 cloves, minced
• Butter: 2 tablespoons
• Olive oil: 1–2 tablespoons
• Chicken broth: 1 cup, low-sodium
• Heavy cream: 3/4 cup (or half-and-half for lighter)
• Dijon mustard: 1–2 teaspoons
• Parmesan cheese: 1/3 cup, finely grated
• All-purpose flour: 1 tablespoon (for thickening)
• Fresh thyme: 1–2 teaspoons leaves (or 1/2 teaspoon dried)
• Fresh parsley: For garnish
• Salt and black pepper: To taste
• Optional: A splash of dry white wine (2–3 tablespoons)

Instructions

 

• Preheat and prep: Heat the oven to 400°F (200°C). Pat the chicken dry and season both sides with salt and pepper.
• Sear the chicken: In a large oven-safe skillet or baking dish, heat 1 tablespoon olive oil over medium-high. Sear chicken 2–3 minutes per side until lightly golden. Remove to a plate. It won’t be cooked through yet.
• Sauté aromatics: Add the butter and remaining oil to the pan. Stir in onion with a pinch of salt. Cook 2–3 minutes until softened. Add mushrooms and cook 5–7 minutes, stirring occasionally, until they release moisture and start to brown.
• Add garlic and thyme: Stir in garlic and thyme. Cook 30–60 seconds until fragrant. If using wine, splash it in and simmer 1 minute to reduce slightly.
• Build the sauce: Sprinkle flour over the mushrooms and stir for 30 seconds. Whisk in chicken broth gradually, scraping up any browned bits. Simmer 2 minutes until slightly thickened.
• Finish with cream: Reduce heat to low. Stir in heavy cream, Dijon, and Parmesan. Simmer gently 1–2 minutes. Taste and season with salt and pepper. The sauce should be creamy and well seasoned.
• Nestle the chicken: Return chicken and any juices to the pan, spooning some sauce and mushrooms over the top. If your skillet isn’t oven-safe, transfer everything to a baking dish.
• Bake: Place in the oven and bake 15–20 minutes, until the chicken reaches an internal temperature of 165°F (74°C). Thicker breasts may need a few more minutes; thighs often cook faster.
• Rest and garnish: Let the chicken rest 5 minutes. Top with chopped parsley. Serve with rice, buttered noodles, mashed potatoes, or crusty bread to catch the sauce.

What Makes This Recipe So Good

This dish delivers comfort with very little effort. The creamy sauce gets depth from sautéed mushrooms, garlic, and a touch of Dijon, so it tastes slow-cooked even though it isn’t. It’s also friendly to swaps—use thighs or breasts, any mushroom you like, and your favorite herbs.

Another bonus: it’s a true bake.

Once you get it into the oven, you can tidy up or set the table while it cooks. The result is juicy chicken, perfectly cooked mushrooms, and a sauce that begs to be spooned over something starchy.

Storage Instructions

Let leftovers cool, then store in an airtight container in the fridge for up to 3–4 days.

Reheat gently on the stovetop over low heat or in the microwave at 50–60% power to keep the sauce from separating. Add a splash of broth or cream if it looks too thick.

For freezing, the texture of the cream sauce can change, but it still works. Freeze up to 2 months.

Thaw overnight in the fridge and reheat slowly, whisking in a bit of cream to bring it back together.

Why This is Good for You

• Protein-rich: Chicken provides steady, satisfying protein to keep you full.
• Mushroom benefits: Mushrooms add fiber, B vitamins, and umami, boosting flavor without extra salt.
• Balanced comfort: The sauce feels indulgent, but pairing with vegetables or a salad makes for a well-rounded plate.
• Customizable: You control the sodium and fat content by choosing low-sodium broth and swapping cream for half-and-half if you prefer.

Pitfalls to Watch Out For

• Soggy mushrooms: Overcrowding the pan steams mushrooms. Cook them in a wide pan and let them brown before adding liquid.
• Curdled sauce: Boiling the cream hard can cause separation. Keep the heat moderate and simmer gently.
• Underseasoning: Taste at each step.

  Mushrooms and cream need enough salt and a little acidity from Dijon to shine.

• Dry chicken: Overbaking dries out breasts. Use a thermometer and pull the chicken at 165°F (74°C).

Variations You Can Try

• Herb swap: Use rosemary or tarragon instead of thyme for a different aroma.
• Bacon boost: Crisp 2–3 slices of chopped bacon first, then cook the mushrooms in the drippings for smoky depth.
• Greens in the mix: Stir in a handful of spinach or kale during the last few minutes of simmering the sauce.
• Cheese change-up: Swap Parmesan for Gruyère or Asiago for a nuttier, melty finish.
• Lighter version: Use half-and-half and skip the flour. Reduce the sauce a bit longer to thicken naturally.
• Gluten-free: Replace flour with 1 teaspoon cornstarch mixed with 2 teaspoons cold water; stir in after adding cream and simmer until thickened.
• Bone-in thighs: Sear as directed, then bake longer (25–30 minutes) until they reach 175°F (80°C) for extra tenderness.

FAQ

Can I use canned mushroom soup instead of making the sauce?

You can, but the flavor and texture are better from scratch.

If you’re short on time, use one can of condensed soup plus 1/2 cup broth, skip the flour, and add garlic and Dijon for brightness.

What mushrooms work best?

Cremini (baby bella) mushrooms offer great flavor and texture. White button mushrooms are mild and affordable. For extra richness, mix in sliced shiitakes or a handful of wild mushrooms.

Do I have to sear the chicken first?

Searing builds flavor and helps the chicken stay juicy, so it’s worth the extra few minutes.

If you skip it, add 5–10 minutes to the bake time and expect a paler color.

How can I make this dairy-free?

Use olive oil instead of butter, and replace cream with unsweetened oat or coconut cream. Skip the Parmesan or use a dairy-free alternative. The sauce will be slightly different but still delicious.

What should I serve with it?

Mashed potatoes, buttered egg noodles, or rice are classic.

For lighter sides, try roasted green beans, steamed broccoli, or a lemony arugula salad.

Can I make it ahead?

You can prepare the sauce and sear the chicken up to a day ahead. Store separately in the fridge. Assemble and bake just before serving, adding a few extra minutes to heat through.

Why did my sauce get thin after baking?

Likely not enough reduction before adding the cream, or extra moisture from mushrooms wasn’t cooked off.

Next time, simmer a bit longer on the stove and make sure mushrooms are browned before adding liquids.
