Ingredients You'll Need

Great soup starts at the grocery store. Look for these staples and treat them like the MVPs they are.

Chicken thighs: Boneless, skinless thighs stay juicy through the long cook. If you only have breasts, reduce the slow-cook time by 30 minutes and shred early so they don’t dry out.

Wild rice: True wild rice (the long, dark grains) holds its shape and adds earthy flavor. Avoid “wild rice blends” with white or brown rice—they’ll turn to mush. If you can only find a blend, add it during the last 90 minutes.

Mirepoix mix: Two large carrots, two celery ribs, and one yellow onion create the classic flavor base. Dice them small so they soften evenly and fit on a spoon.

Garlic: Three cloves, smashed and peeled. Fresh garlic mellows beautifully in the slow cooker; jarred paste works in a pinch—use 1 tablespoon.

Low-sodium chicken broth: Swanson or Pacific are my go-tos. Low-sodium lets you control salt after cooking, especially important when the soup reduces.

Dried thyme & bay leaves: These hardy herbs bloom in the long heat. Rub thyme between your palms to wake up the oils.

Half-and-half: Adds silky body without the weight of heavy cream. Swap in full-fat coconut milk for a dairy-free version; the faint coconut backdrop is surprisingly cozy.

All-purpose flour: Just two tablespoons whisked with butter (or olive oil) thickens the soup ever so slightly so it coats the back of a spoon.

How to Make Slow Cooker Chicken and Wild Rice Soup for Meal Prep

Prep the produce

Rinse carrots, celery, and onion under cold water. Peel carrots and trim the ends. Dice all vegetables into ¼-inch pieces so they cook evenly and fit on a spoon. Mince garlic. Store everything together in a zip-top bag if you’re prepping the night before.

Rinse the wild rice

Place wild rice in a fine-mesh strainer and rinse under cool water for 30 seconds, swishing with your hand. This removes excess starch and any broken bits that could cloud the broth.

Layer the slow cooker

Add chicken thighs to the bottom of a 6-quart slow cooker. Scatter rice, carrots, celery, onion, garlic, thyme, bay leaves, 1 teaspoon kosher salt, and ½ teaspoon black pepper on top. Pour 6 cups broth over everything; do not stir. Cover and cook on LOW 6–7 hours or HIGH 3–3½ hours.

Shred the chicken

When thighs reach 175°F on an instant-read thermometer, transfer them to a cutting board. Let rest 5 minutes, then shred with two forks or your stand mixer on low speed for 30 seconds (my favorite weeknight hack). Discard bay leaves.

Make the roux

Melt 2 tablespoons unsalted butter in a small saucepan over medium heat. Whisk in flour and cook 90 seconds until pale gold and nutty. Whisk in ½ cup of hot broth from the slow cooker until smooth; stir this slurry back into the soup to thicken slightly.

Finish with cream

Stir in shredded chicken and ½ cup half-and-half. Cover and cook on HIGH 10 minutes more to heat through. Taste and adjust salt; the rice will have absorbed some broth, so add extra if you like a looser soup.

Portion for meal prep

Ladle soup into 2-cup glass containers; leave ½ inch at the top for expansion if freezing. Cool completely, then refrigerate up to 4 days or freeze up to 3 months. Reheat gently with a splash of broth or water.

Expert Tips

Don’t overcook the rice

Wild rice splits when it’s done, revealing the chewy interior. If left too long it blossoms open and can taste cottony. Check at the 6-hour mark on LOW.

Cool quickly for food safety

Spread hot soup into shallow metal pans and refrigerate uncovered 30 minutes, then cover. This keeps bacteria from hanging out in the lukewarm danger zone.

Rehydrate with broth, not water

When reheating, use stock to thin the soup; water dilutes the flavor you worked for.

Label before freezing

Write the date and “add ½ cup broth when reheating” on masking tape. Future you will be grateful.

Variations to Try

Storage Tips

Refrigerate cooled soup in airtight containers up to 4 days. Reheat single servings in the microwave 2–3 minutes, stirring halfway, or on the stovetop over medium until steaming.

To freeze, ladle into labeled quart-size freezer bags, press out excess air, and freeze flat on a sheet pan. Once solid, stack vertically like books to save space. Thaw overnight in the fridge or submerge the sealed bag in cool water for 30 minutes, then heat as above.

Cooked wild rice continues to absorb liquid, so the soup thickens in storage. Keep an extra carton of broth on hand to loosen it when reheating.

Frequently Asked Questions

Brown rice cooks faster and will disintegrate into porridge after 6 hours. If you must substitute, add ¾ cup par-cooked brown rice during the last 45 minutes.

The roux gives body, but you can skip it for a brothy soup. For a gluten-free option, whisk 1 tablespoon cornstarch with cold broth and stir in at the end.

Only if your slow cooker is 8 quarts or larger. Overfilling prevents proper heat circulation and can crack the insert. Split into two 6-quart cookers if needed.

Temper the half-and-half by whisking in ½ cup hot broth before adding it to the slow cooker. Keep the setting on WARM or LOW—never boil after dairy is added.

Yes, but leave out the cream in the base. Freeze the soup plain, then stir in 1–2 tablespoons whole milk when reheating individual toddler portions.

Altitude, age of rice, and slow-cooker wattage vary. If grains are still firm after 7 hours, add ½ cup hot broth, cover, and continue on HIGH 30–45 minutes more.
