Slow Cooker Chicken with Root Vegetables

This slow cooker chicken with root vegetables is the kind of cozy, low-effort dinner that still tastes like you really did something. Chicken turns tender, the vegetables soak up a savory herb broth, and your kitchen smells amazing while the crockpot does the work.

It’s a perfect weeknight meal (minimal prep, hands-off cooking) and it’s also great for Sunday meal prep because the leftovers reheat beautifully. Serve it as-is like a stew, or spoon it over mashed potatoes, rice, or buttered egg noodles.

Ingredients

• 2 to 2 1/2 lb bone-in, skin-on chicken thighs (or boneless thighs)
• 1 1/2 lb baby Yukon gold potatoes, halved (or large potatoes, chunked)
• 3 large carrots, cut into 1-inch pieces
• 2 parsnips, cut into 1-inch pieces
• 1 large yellow onion, thickly sliced
• 4 cloves garlic, minced
• 1 1/2 cups low-sodium chicken broth
• 2 tbsp tomato paste
• 2 tbsp olive oil
• 1 tbsp Dijon mustard
• 1 1/2 tsp kosher salt (plus more to taste)
• 1 tsp black pepper
• 1 1/2 tsp dried thyme (or 1 tbsp fresh)
• 1 tsp dried rosemary (or 1 tbsp fresh, chopped)
• 1 bay leaf
• 2 tbsp all-purpose flour (optional, to thicken)
• 2 tbsp chopped fresh parsley (for serving)

How to make slow cooker chicken with root vegetables

1) Build the vegetable base. Add potatoes, carrots, parsnips, onion, and garlic to the slow cooker and toss with olive oil, salt, pepper, thyme, and rosemary.

2) Mix the broth. Whisk chicken broth with tomato paste and Dijon, then pour it over the vegetables. Add the bay leaf.

3) Add the chicken. Nestle chicken thighs on top of the vegetables. If using skin-on thighs, place them skin-side up.

4) Slow cook. Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until chicken is very tender and potatoes are fork-soft.

5) Optional: thicken the broth. If you want a stew-like consistency, whisk flour with a few tablespoons of hot broth to make a slurry, stir it into the slow cooker, and cook on HIGH for 10–15 minutes until slightly thickened.

6) Finish and serve. Discard the bay leaf, taste and adjust seasoning, and sprinkle with parsley.

Best chicken to use

• Bone-in thighs: Most flavorful and forgiving for slow cooking.
• Boneless thighs: Still juicy and easy to serve; start checking early on HIGH.
• Chicken breasts: Works, but can dry out. If using breasts, cook on LOW and aim for the shorter end of the time range.

Root vegetables that work well

• Potatoes: Yukon gold or red potatoes hold their shape nicely.
• Carrots + parsnips: Classic combo; parsnips add sweet, earthy depth.
• Turnips or rutabaga: Swap in for part of the potatoes for a slightly peppery flavor.
• Sweet potatoes: Great, but softer—add in the last 2–3 hours on LOW if you want firmer chunks.

Make it even better (easy upgrades)

• Brown the chicken first: Sear thighs in a skillet for 2–3 minutes per side for deeper flavor (optional, but delicious).
• Add a splash of acid: Stir in 1–2 teaspoons apple cider vinegar or a squeeze of lemon at the end to brighten everything up.
• Go herby: Add fresh thyme/rosemary at the end for a fresher aroma.

What to serve with it

• Crusty bread or warm dinner rolls
• Simple side salad (vinaigrette cuts the richness)
• Rice, mashed potatoes, or egg noodles to soak up the broth

Storage and reheating

• Refrigerate: Store in an airtight container up to 4 days.
• Freeze: Freeze up to 3 months (thaw overnight in the fridge).
• Reheat: Warm gently on the stove or in the microwave. Add a splash of broth if needed.

Recipe notes and FAQs

• Do I need to add flour? No. The broth stays more like a light soup without it. If you want it thicker, use the optional slurry.
• Can I put the chicken under the vegetables? You can, but chicken on top stays easier to serve and lets the skin (if using) stay less soggy.
• How do I keep vegetables from getting mushy? Cut them into larger chunks and avoid overcooking on HIGH if your slow cooker runs hot.
