How to Make Slow Cooker French Onion Chicken and Rice

Step 1: In a large skillet over medium heat, melt butter and oil. Add sliced onions and cook until they're tender and golden brown. Set aside.

Step 2: Season chicken breasts with garlic powder, paprika, and black pepper. Quickly sear in the same skillet until browned on both sides (don't fully cook).

Step 3: In a large bowl, combine cream of chicken soup, chicken broth, garlic powder, black pepper, white rice, and onion soup mix.

Step 4: Pour the mixture into your slow cooker, then layer the seared chicken breasts on top. Add the caramelized onions over the chicken.

Step 5: Cover and cook on high for 3 hours or low for 5 hours, until chicken is cooked through and rice is tender.

Step 6: Add Swiss cheese slices on top, cover for 5 minutes to melt, garnish with parsley, and serve warm.

Substitutions and Variations

• Use boneless chicken thighs instead of breasts for extra flavor.
• Swap Swiss cheese for Gruyère for a more authentic French onion taste.
• Replace white rice with instant rice (add during the last 30 minutes of cooking).
• Mix in mushrooms or spinach for a veggie boost.

What to Serve with Slow Cooker French Onion Chicken and Rice

This dish pairs perfectly with steamed green beans, roasted broccoli, or a simple side salad for a balanced dinner. You can also add a slice of garlic bread to soak up that creamy sauce and you have the ultimate cozy meal combo.

Storage and Freezing

Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave or oven with a splash of broth or milk to keep it creamy. For longer storage, freeze for up to 2 months just thaw overnight in the fridge before reheating.

FAQs

Can I use chicken thighs instead of breasts?

Yes, boneless skinless chicken thighs work great and add more flavor.

Can I make this with brown rice?

You can, but it will need more liquid and a longer cooking time. White rice works best here.

What kind of cheese is best?

Swiss cheese is classic, but Gruyère adds a rich, nutty flavor that's also amazing.

Why did my rice turn mushy?

It likely overcooked. Make sure to turn off the slow cooker once the rice is tender and the liquid is absorbed.
