Slow Cooker Creamy Celery Root Barley Rice
A French-inspired side dish pairing tender barley with roasted celery root in a silky cream sauce infused with thyme and shallots. The slow cooker does the work, melding flavors gently while the barley absorbs the savory broth and releases its starch to create natural creaminess. Perfect alongside roasted chicken, beef, or pork.

Steps
Before you start
- Peel and cut the celery root into ¾-inch cubes ahead of time; they will brown if held long, so prep just before cooking
- Have a 5-to-6-quart slow cooker ready
- Measure out the broth, cream, and barley so everything is within arm's reach
Combine in slow cooker
- Add the rinsed barley, celery root cubes, minced shallots, thyme sprigs, and butter to the slow cooker.
- Pour in the vegetable broth and stir gently to combine.
- Season with ½ teaspoon kosher salt and a pinch of black pepper.

Tip: Do not add the cream yet; it will curdle if it simmers for the full cooking time.
Cook on low
- Cover the slow cooker with the lid and cook on low for 4 to 4.5 hours.
- The barley should be tender but still have a slight chew, and the celery root should be creamy when you press it with a fork.
- The liquid should be mostly absorbed with just a thin layer of broth at the bottom.

Good to know
Tips
- To test if the barley is fully cooked without opening the lid, listen: the slow cooker should be nearly silent with no audible simmering sound.
- If the barley is still firm after 4.5 hours, continue cooking in 30-minute intervals, checking between each, until tender.
- Celery root oxidizes quickly once cut; if prepping ahead, toss the cubes with a squeeze of lemon juice and cover tightly until ready to cook.
- For a richer version, use half chicken broth and half vegetable broth, and stir in 2 tablespoons Dijon mustard along with the cream.
Make ahead
The barley can be cooked completely (through step 2) up to 2 days ahead. Cool, cover, and refrigerate. Reheat gently in the slow cooker on low with 2–3 tablespoons broth or cream, stirring occasionally, for about 45 minutes until warmed through, then stir in fresh cream and season to taste.
Storage & reheating
Room temperature: up to 2 hours. Refrigerator: cover and store for up to 3 days; reheat gently on the stovetop over low heat with a splash of broth or cream, stirring often. Freezer: cool completely, transfer to an airtight container, and freeze for up to 2 months. Thaw overnight in the refrigerator and reheat as directed for the fridge.
Substitutions
- pearl barley → farro or spelt berries. Both have a similar chewy texture. Increase cooking time by 30 minutes if using whole farro or spelt.
- celery root (celeriac) → parsnips, peeled and cut into ¾-inch cubes. Parsnips are sweeter and will add a gentle sweetness to the dish; use the same weight.
- heavy cream → crème fraîche or sour cream. Crème fraîche adds tang and a slightly richer mouthfeel. Add it at the same stage just before serving.
- vegetable broth (or chicken broth) → chicken broth or mushroom broth. Chicken broth will add savory depth; mushroom broth will enhance the earthy character of the celery root.
