Recipe tested & approved
A baked chicken casserole with shredded sweet potatoes, vibrant sautéed vegetables and a creamy sauce. Mozzarella replaced with cheddar, carrots swapped for parsnips for earthier sweetness. Sauce thickened with cornstarch instead of flour to keep it silky. Cook times shifted slightly; look for bubbling edges and golden topping. Salt and pepper adjust for taste and moisture levels. Perfect for when you want rustic warmth yet neat layers. Ideal for midweek mains or casual weekend dinners. Focus on tactile cues like when the sauce clings to the spoon or potatoes soften under gentle poke. Avoid mushy veggies by quick sauté over medium heat. Keep some extra broth handy to loosen sauce if it thickens too much. A nut-free, egg-free dinner that won’t disappoint.

Ever wrestled with soggy casseroles? Me too. Turned out I need sharper cheese to keep melting in check. Cheddar over mozzarella, trust me. Swapped carrots for parsnips - more depth, less sweetness, brighter flavor play with chicken. Sauce thickened with cornstarch instead of flour; makes it silky, no pasty taste. Key is letting veggies sweat and soften just right before piling layers. Don’t drown that sauce with too much broth at once or it gets runny doom. Oven temp lowered a bit; chance for cheese to brown gently while topping sets. I watch for bubbling around edges, slight golden crust forming. And sweet potatoes? Grated, not sliced thick. They bed the cheese like a cushion, no soggy swamp underneath. Resting baked dish is gold. Sounds simple, but little things make or break. Kitchen smells will pull you into cozy mode before even tasting. State of casserole tells you all you need. I’ve learned to eyeball it; recipes only guide, intuition wins here.
Ingredients
- 15 ml (1 tbsp) olive oil

- 1 leek, thinly sliced white and light green parts only
- 600 ml (2 1/2 cups) cooked shredded chicken
- Salt and pepper
Sauce
- 45 ml (3 tbsp) butter
- 30 ml (2 tbsp) cornstarch

- 400 ml (1 2/3 cups) peeled and grated sweet potatoes (about 1 medium)
- 400 ml (1 2/3 cups) sharp cheddar cheese, grated
About the ingredients
Don’t scold yourself for swapping out carrots to parsnips. Those long, knobby roots bring earthiness instead of simple sweetness, which balances chicken and cheese better. Red pepper adds color plus light sweet bitterness. Leeks like onions but gentler, watch them not burn but soften until translucent and silky; burnt leeks ruin the dish. Cooked chicken? Ideal for leftovers, any white or dark meat shredded works. Salt sparingly; broth adds salt too. Butter and cornstarch for sauce means no thick flour taste, but whisk steadily. Cornstarch sauce thickens faster and stays smooth, but if overcooked will turn glue-like—so pull off heat when just thick. Sweet potato topping must be grated finely, else baking takes forever and texture suffers. Sharp cheddar holds flavor and melts well without separating like mozzarella can sometimes. Oil in pan for veggies is crucial; no splash means sticking and uneven cooking. If pressed, swap chicken broth for veggie broth but expect less savory depth. Easy to add herbs like thyme or rosemary here; fresh or dried. No nuts or eggs here, allergy friendly with great flavor.
Method
Veggies and Chicken
- Preheat oven to 185 °C (365 °F). Listen for that preheat beep or visual cue. Heat olive oil over medium heat in skillet until it shimmers but no smoke. Toss in parsnips, bell pepper, and leek. Stir often, about 6 minutes. Should hear gentle sizzle, vegetables start to soften but still hold shape. Add chicken, stir to warm through. Season with salt and pepper but lightly. Remember chicken and broth add salt later.
- Transfer mixture into a 38 x 20 cm (15 x 8 inch) baking dish, spread evenly. Slight bubbling on edges will signal done later so leave room on sides.
Sauce
- In saucepan, melt butter over medium heat, bubbling but not brown. Whisk in cornstarch all at once, stir constantly for about 1-2 minutes until thick and glossy paste forms. Slowly pour in chicken broth in thin steady stream. Whisk vigorously to avoid lumps. Sauce will thicken gradually. When it coats back of spoon and holds finger mark, it's ready. Pour sauce evenly over chicken-veg mixture. Don’t let it pool too much on edges.
Topping
- Mix grated sweet potatoes and cheddar in a bowl. The sweet potato texture keeps cheese from melting into a greasy mess. Drizzle a tiny bit of oil on top if cheddar looks dry. Spread evenly atop casserole. Season lightly with salt and pepper again. Too much salt, and cheese gets rubbery.
Baking
- Bake uncovered for about 40-45 minutes. Watch casserole edges bubble, cheese melts and turns golden with some spots browning. Sweet potatoes soften but still have slight bite. Tap topping gently - it should feel set but not mushy. If cheese browns too fast but potatoes aren’t done, cover loosely with foil.
- Pull out from oven. Let rest 5 minutes before serving. Resting lets sauce thicken slightly and settles all those flavors. The aroma should be cozy, sweet hints from the topping with light savor of chicken and leek. If sauce looks too thick at bottom next time, add small splash broth post-rest. Sauce texture most important here - silky, not gluey.
- Serve warm with simple sided salad or steamed greens for balance.
Cooking tips
Start by prepping everything before heating oil. Don’t crowd pan when sautéing; vegetables sweat and brown unevenly. Watch for sizzling that softens to gentle bubbles; too hot and outside chars, too low and veggies stew, losing texture. Chicken added late to warm through, avoid drying it out. Transfer to baking dish without pressing down; keep air pockets for sauce to seep in. Sauce – melt butter first, low simmer avoids browning which adds bitterness. Whisk in cornstarch evenly or risk lumps; whisk constantly. Broth adds liquid, stir slowly for smoothness. Stirring stops butter from separating. Look for glossy shine and medium thickness. Pour over chicken mix before adding sweet potato-cheese topping evenly, no lumps or clumps. Salt cheese topping lightly, not heavy. Baking – watch time but trust visual cues: edges bubbling hot and bubbly, mild caramelized crust on cheese, sweet potatoes soft but intact. Cover loosely if browning too fast. Let cool off heat before serving. All that bubbling means hot inside, give a rest so sauce thickens and aroma settles. If sauce too thick, thin with broth after resting. Don’t over-salt at end or cheese can taste tacky. Cleanup easy if baking dish sprayed or brushed lightly with oil, cheese loves sticking, don’t skip.
Chef's notes
- 💡 Heat olive oil just until it shimmers but no smoke. Medium heat only. Vegetables sweat and soften, not burn or stew. Stir often. Quick sauté important to keep shape while softening; else mushy.
- 💡 Whisk cornstarch fully into melted butter before broth, no lumps. Add broth slowly, whisk constantly. Sauce thickens gradually; stops when it coats spoon and holds finger mark. Watch carefully so it’s not gluey.
- 💡 Grate sweet potatoes fine. Thick chunks make topping dense and undercooked. Sharp cheddar holds its shape, won’t melt into greasy pools like mozzarella can. Drizzle tiny bit oil if topping looks dry before baking.
- 💡 Watch casserole edges for bubbling, cheese melting with golden spots. Tap topping gently mid-bake; should feel set, not mushy. If browning too fast but potatoes still hard, cover loosely with foil to slow crust forming.
- 💡 Rest after baking for 5 minutes. Sauce thickens slightly and flavors settle. If too thick on bottom next time, add small splash broth after resting, not before. Salt topping lightly since broth and chicken add salt already.
Common questions
Can I swap parsnips for carrots?
Yes but carrots sweeter, change flavor balance. Parsnips brown gentler, earthy tone. Adjust seasoning, watch softening time slightly. Vegetables sauté similarly but carrots soften faster sometimes.
What if sauce lumps or too thick?
Whisk cornstarch paste well first, add broth slow with vigorous stirring. If lumps form, strain or whisk hard off heat. Too thick? Thin with broth carefully after resting; hot sauce won’t thin well.
Cheese topping browns too fast?
Cover loosely with foil midway. Oven hot spots cause spots on cheddar. Adjust temp lower if needed. Less cheese or oil drizzle helps slow browning if uneven or rubbery texture forming.
How to store leftovers?
Cool completely. Refrigerate in airtight container up to 3-4 days. Reheat covered, add splash broth if sauce thickened too much. Freeze portions wrapped well, thaw overnight. Texture softens after freezing a bit.
