Note From Andi:

This recipe gives me total retro dinner vibes - the kind of meal your mom or grandma might've made straight from the pantry. I love that it uses simple staples like onion soup mix, mushrooms, and chicken to create a rich, flavorful sauce in no time.

The best part? Everything cooks in one pan, and that thick gravy-style sauce gets poured right over fluffy rice.

Step-By-Step Instructions 👇👇

STEP 1: Prep the Base

Cook your rice in a rice cooker or on the stovetop according to package directions, then set aside. In a small bowl, whisk together 1 envelope onion soup mix, 1¼ cups water, and 1 Tbsp Worcestershire sauce. In another small bowl, stir together 1 Tbsp cornstarch and 1 Tbsp cold water; set both aside for later.

STEP 2: Brown the Chicken

Slice 1 lb boneless chicken breasts into bite-sized pieces. Heat 1 Tbsp salted butter in a large skillet over medium heat. Add the chicken and cook for 1-2 minutes per side, just until lightly browned (it doesn't need to be fully cooked yet). Remove chicken to a plate and set aside - leave any liquid in the pan.

STEP 3: Sauté the Vegetables

In the same skillet, add ½ cup chopped onion, ½ cup green bell pepper, and 1 can of drained mushrooms. Sauté for 2-3 minutes until the bell pepper is tender and the onions start to soften.

STEP 4: Build the Sauce & Simmer

Pour the onion soup mixture into the skillet with the veggies, stirring to combine. Add the browned chicken back to the pan, mix everything together, reduce the heat to low, and cover. Simmer for 8-10 minutes, or until the chicken is cooked through.

STEP 5: Thicken the Sauce

Transfer the chicken mixture to a serving bowl. Pour in the cornstarch slurry (the mix of 1 Tbsp cornstarch + 1 Tbsp cold water) into the pan juices. Bring to a gentle boil, stirring constantly for 1-2 minutes, until the sauce thickens into a rich gravy. Pour it over the chicken.

STEP 6: Serve & Enjoy

Serve the chicken and sauce over warm cooked rice. Spoon extra sauce on top - it's the best part!

Recipe Tips

Cut chicken evenly so it cooks at the same rate.
Don't skip the cornstarch slurry - it's what turns the sauce into gravy.
Use a wide skillet so the chicken and veggies brown instead of steam, and the sauce thickens faster as the liquid evaporates.
Want a richer sauce? Replace ½ cup of the water with low-sodium chicken broth.
Make it creamy: Stir in 2 Tbsp sour cream or a splash of heavy cream before serving.

Variations and Substitutions

Protein swaps: Use boneless chicken thighs or pork chops
Veggie add-ins: Try adding sliced carrots, celery, or frozen peas.
Flavor twist: Add a dash of soy sauce or balsamic vinegar to deepen the flavor.
Low-sodium option: Choose reduced-sodium onion soup mix and broth.
No mushrooms? Skip them or replace them with frozen green beans.

What To Serve With

Pair with dinner rolls or garlic bread to soak up the sauce.
Add a side of steamed broccoli or green beans for color.
Serve with my kale chickpea salad to balance the richness.
For a cozy twist, spoon it over mashed potatoes instead of rice.

How To Store Leftovers

Fridge: Store in an airtight container for up to 4 days.
Reheat: Warm in a skillet or microwave with a splash of water or broth to loosen the sauce.
Freezer: Not ideal - the sauce can separate once thawed.

Dinner Rhythm Tip: Keep a few packets of onion soup mix in your pantry - it's one of the easiest shortcuts for making instant sauces or gravies.

FAQs

Can I use homemade onion soup mix?

Yes! Mix 3 Tbsp dried minced onion, 2 tsp beef bouillon granules, ½ tsp onion powder, ½ tsp garlic powder, and ¼ tsp dried parsley to replace one store-bought packet.

Can I make this with chicken thighs?

Absolutely - boneless thighs stay juicy and work beautifully here.

Can I double the sauce?

Yes, just double the soup mix, water, and Worcestershire. You'll want extra sauce if serving a larger family.
