1 cup cauliflower florets Fresh or frozen, broken into bite‑size pieces.

1 cup Brussels sprouts, halved Trimmed and sliced for even cooking.

2 medium carrots, sliced thin Adds natural sweetness and color.

1 small parsnip, diced Optional, for extra earthiness.

2 tbsp olive oil For roasting; can replace with avocado oil.

1 cup low‑sodium chicken broth Ensures moisture without excess salt.

½ cup plain Greek yogurt Adds creaminess; use dairy‑free yogurt if needed.

1 tsp dried thyme Or 1 tbsp fresh thyme leaves.

Salt & freshly ground black pepper To taste.

Instructions

Preheat & Prepare

Preheat the oven to 400°F (200°C). Toss the cauliflower, Brussels sprouts, carrots, and parsnip with olive oil, thyme, salt, and pepper on a large baking sheet. Spread evenly for even caramelisation.

Pro Tip: Roast vegetables for 12‑15 minutes before adding chicken for extra depth.

Sear the Chicken

While vegetables roast, heat a non‑stick skillet over medium‑high heat. Add a drizzle of olive oil, then sear the cubed chicken for 3‑4 minutes until lightly browned but not fully cooked. This locks in juices.

Pro Tip: Do not overcrowd the pan; work in batches if necessary.

Combine & Add Broth

Transfer the partially roasted vegetables to a 9‑inch casserole dish. Add the seared chicken, then pour the low‑sodium broth over everything. The broth will steam the chicken to finish cooking while keeping the dish moist.

Pro Tip: If you prefer a thicker sauce, whisk 1 tsp cornstarch with 2 tbsp water and stir into the broth.

Bake the Casserole

Cover the dish with foil and bake for 20 minutes. Remove the foil, stir gently, then dollop Greek yogurt on top. Return to the oven uncovered for another 10 minutes, allowing the yogurt to set and lightly brown.

Pro Tip: Add a sprinkle of fresh herbs just before serving for brightness.

Rest & Serve

Let the casserole rest for 5 minutes after removing from the oven. This allows flavors to meld and makes slicing easier. Serve hot, garnished with a drizzle of extra‑virgin olive oil or a squeeze of lemon if desired.

Expert Tips

Tip #1: Uniform Cutting

Cut all vegetables to a similar size (≈½‑inch) so they roast evenly and finish at the same time, preventing soggy patches.

Tip #2: Yogurt Temperature

Allow the Greek yogurt to reach room temperature before adding it; this prevents curdling when it meets the hot casserole.

Tip #3: Freeze‑Proof

Cool completely, then store in airtight containers. Reheat gently on the stovetop with a splash of broth to keep it moist.

Storage & Variations

Store leftovers in a sealed container in the refrigerator for up to 3 days. Reheat in the microwave or a covered skillet with a splash of broth. Swap chicken for firm tofu for a vegetarian version, or add a handful of kale in the last 5 minutes for extra greens.

Frequently Asked Questions

Yes. Thaw them briefly and pat dry before tossing with oil. Frozen veggies may release extra moisture, so extend the uncovered baking time by 5 minutes to achieve crispness.

Use skinless chicken, limit oil to the amount listed, and choose non‑fat Greek yogurt. Avoid adding cheese or butter; the broth and yogurt provide sufficient richness.

A simple mixed green salad with a lemon‑vinaigrette balances the warm casserole. For extra carbs, serve a modest portion of quinoa or whole‑grain couscous.
