Creamy Mushroom Chicken with Parmesan Rice Bowl

I first made this dish to use up leftover French onion soup years ago. The family loved it so much I began making it from scratch: browning onions, adding a packet of dry onion soup mix to the broth, and stirring in caramelized mushrooms for an earthy, luxurious flavor. Over the years it became a family favorite, especially with my youngest daughter.

This is a true one‑pot meal: simple to prepare, versatile, and forgiving. It’s equally good cooked from scratch or assembled with leftover chicken and rice. Below you’ll find clear instructions for both methods as well as substitutions and a dairy‑free option.

I hope your family enjoys it as much as mine does.

Ingredients needed to prepare this recipe

• Mushrooms: Cremini (baby bella) are my usual choice, but white button or oyster mushrooms work well too.
• Olive oil and butter: Butter gives a creamy flavor while oil helps prevent the butter from burning.
• Yellow onion: Mild and balanced; white or red onions are fine if preferred.
• Garlic: Use the amount you like.
• Thyme: Dried thyme leaves are called for; substitute fresh thyme (add sprigs to the pan and remove stems before serving) or use ground thyme at half the amount.
• Dry onion soup mix: A convenient flavor shortcut; see the substitutions section for an easy homemade mix.
• Chicken broth: Use good quality broth or a base like Better Than Bouillon mixed with water.
• Chicken: 12–16 ounces boneless, skinless breasts or thighs, or an equal amount of pre‑cooked chicken or rotisserie chicken.
• Rice: 1 cup dry rice (or 3 cups cooked). White rice cooks faster; brown and wild rice require more time—see notes below.
• Salt and black pepper
• Egg yolks + cream or half‑and‑half: Two egg yolks and 1/2–1 cup cream create a rich, silky finish. See dairy‑free option below.
• Lemon juice: Fresh lemon brightens and balances the cream.
• Fresh parsley: Chopped Italian flat‑leaf parsley adds color and freshness (optional).

Additions and substitutions

• Onion/garlic alternative: For those sensitive to alliums, substitute chopped fennel for a mild, aromatic flavor.
• Homemade dry onion soup mix: Combine 1 tsp onion powder, 1 tsp celery seed, 1 tsp dried parsley, 1/2 tsp paprika, and either 2 tsp crushed beef bouillon cubes or 1 tsp beef base.
• Leftover French onion soup: Omit raw onions and add the leftover soup, plus broth to total 4 cups liquid.
• Dairy‑free: Use extra creamy oat milk, or blend silken tofu with soy milk 1:1 to replace cream.

Step-by-step photos and instructions

Clean and slice the mushrooms. Heat olive oil and butter in a large saucepan, dutch oven, or braiser (about 3.8 quarts or larger). When the butter melts, add mushrooms and cook over medium heat until they begin to sweat. Season with salt and pepper and continue to cook, stirring frequently, until deeply golden. Transfer mushrooms to a plate.

If the pan needs more fat, add a tablespoon of oil, then add the chopped onion and cook over medium heat until it begins to brown. Add garlic, thyme, and the dry onion soup mix and cook for about a minute to release the aromas.

Pour in 4 cups of chicken broth, scraping up any browned bits from the bottom of the pan. If you’re cooking raw rice and raw chicken together, add them now. Increase heat to bring the liquid to a boil, then lower to a gentle simmer and cover.

Simmer until the chicken is cooked through and the rice is tender, about 20–25 minutes for white rice. Check halfway through and add a splash more broth if the pan seems dry.

If using pre‑cooked rice and chicken: Bring the broth to a boil, then simmer uncovered about 10 minutes. Stir in cooked rice and cooked chicken and heat another 5 minutes.

When the chicken is cooked, remove it to a plate and shred with two forks into bite‑sized pieces. Return the shredded chicken to the pan and stir to combine.

In a small bowl, whisk together the egg yolks and the cream or half‑and‑half until smooth.

Turn off the heat. Slowly pour the egg yolk and cream mixture into the pan while stirring constantly to temper and thicken the sauce gently.

Squeeze juice from half a lemon into the pan, stir in the reserved mushrooms, and taste for seasoning. Add more lemon juice, salt, or pepper as desired.

Return the pan to low heat and warm gently until everything is just simmering and the sauce is glossy. Serve sprinkled with chopped parsley.

Serving suggestions

This dish pairs beautifully with crusty bread, toast, warm dinner rolls, or flaky buttermilk biscuits to soak up the creamy sauce. For a full comfort food spread, serve with a simple green salad or steamed vegetables to balance the richness.

For those who like to bake, homemade white bread, honey wheat sandwich loaves, dinner rolls, or buttermilk biscuits make excellent accompaniments.
