2 large sweet potatoes, peeled and cubed Butternut squash works as a substitute.

1 ½ cups low‑sodium chicken broth Ensure gluten‑free if needed.

½ cup Greek yogurt (plain) Replace with coconut yogurt for dairy‑free.

2 cloves garlic, minced Fresh or jarred minced garlic.

1 medium onion, diced Yellow or white onion works.

1 tbsp olive oil Helps sweet potatoes caramelize.

1 tsp smoked paprika Adds subtle smoky depth.

Salt and freshly ground black pepper Season to taste at each step.

Instructions

Season and arrange chicken

Trim chicken into bite‑size pieces and season with salt, pepper, and smoked paprika. Place them in the slow cooker’s bottom layer, creating an even base for even cooking.

Pro Tip: Pat the chicken dry before seasoning for better browning.

Add sweet potatoes and aromatics

Peel and cube sweet potatoes into 1‑inch pieces. Scatter the cubes over the chicken, then drizzle with a tablespoon of olive oil and sprinkle minced garlic and diced onion for added flavor.

Pro Tip: Toss potatoes with a pinch of brown sugar for a caramelized finish.

Add broth and spinach

Pour the low‑sodium chicken broth over the vegetables, ensuring everything is just covered. Add fresh spinach leaves on top; they will wilt into the liquid as it cooks.

Pro Tip: If using frozen spinach, thaw and squeeze out excess water first.

Slow‑cook

Cover the slow cooker and set to low for 4 hours (or high for 2 hours). Resist the urge to lift the lid; steady heat creates tender meat and infused vegetables.

Pro Tip: Add a splash of lemon juice just before serving for brightness.

Finish with yogurt

After cooking, stir in Greek yogurt (or dairy‑free alternative) until smooth. Adjust seasoning with extra salt or pepper, then serve hot, garnished with chopped parsley if desired.

Pro Tip: Use room‑temperature yogurt to avoid curdling.

Expert Tips

Tip #1: Sweeten the potatoes

Toss sweet‑potato cubes with a pinch of brown sugar before cooking; the slow‑cook heat gently caramelizes them, deepening natural sweetness without added syrup.

Tip #2: Thicken the sauce

Mix 1 Tbsp cornstarch with cold water and stir into the casserole during the last 30 minutes for a silkier, richer sauce.

Tip #3: Preserve spinach color

Add spinach in the final 15 minutes; it wilts perfectly while retaining a bright green hue and a pleasant texture.

Storage & Variations

Store leftovers in airtight containers in the refrigerator for up to 4 days. Freeze individual portions for up to 2 months; reheat gently on the stove or microwave. Swap chicken for turkey, or replace spinach with kale for a heartier bite. Add a splash of coconut milk for a dairy‑free, creamy twist.

Frequently Asked Questions

Yes, set the pressure cooker to high pressure for 25 minutes, then quick‑release. The texture will be similarly tender, though flavors meld a bit faster.

Absolutely. Stirring yogurt after the cooking cycle prevents curdling and keeps the sauce creamy while preserving the probiotic benefits of the live cultures.

Frozen chopped spinach works well—thaw, squeeze out excess moisture, and add during the last 30 minutes. The flavor remains, though the texture is softer.

Replace Greek yogurt with coconut‑based yogurt or a cashew cream blend, and ensure the broth is dairy‑free. The dish stays rich and satisfying without dairy.
