Soft gnocchi, tender chicken, bubbling cheese Baked Chicken Gnocchi Casserole is the kind of dinner that makes the whole house smell like comfort before you even sit down.
Last September, I was deep into testing one-pan dinners as the evenings started cooling off. After too many tired weeknights staring at the fridge with zero inspiration, this became my reset dish creamy enough to feel cozy, but not heavy like a January stew. The trick I kept coming back to: letting the gnocchi finish cooking right in the sauce so it absorbs all that flavor instead of just sitting on top. After testing it six or seven times, that step made all the difference.

Why You’ll Love This Baked Chicken Gnocchi Casserole
Here’s why this one keeps showing up on the dinner rotation: it tastes like you spent the evening cooking, but the oven does most of the work. On those evenings when the air starts to shift and you want something warm and satisfying without a heavy braise, this is exactly the answer.
It’s cozy but not slow. Creamy without being too rich. And the whole thing comes together in under 30 minutes which on a tired weeknight feels like a small miracle.
What Makes This Recipe Work
The flavor backbone is the roasted red pepper pesto. It brings a smoky, slightly sweet depth that makes the sauce taste far more layered than the ingredient list suggests. Combined with a splash of double cream and tomato puree, it coats every piece of gnocchi and chicken in something genuinely craveable.
- Fresh gnocchi softens perfectly as it bakes right into the sauce no separate boiling step needed
- Baby spinach wilts down into the dish without overpowering anything
- Torn mozzarella bubbles up into golden, pull-apart patches on top
- Hot chicken stock keeps the sauce loose and saucy throughout
How to Make It
Preheat your oven to 200C/400F. Everything goes into one baking dish that’s the whole setup.
- Toss the chopped chicken breast with olive oil, salt, black pepper, and dried oregano directly in your baking dish. Bake for 10 minutes.
- Remove from the oven and add the baby spinach, hot chicken stock, fresh gnocchi, roasted red pepper pesto, sliced red bell pepper, double cream, and tomato puree. Stir to combine.
- Dot torn mozzarella across the top, then return to the oven for 15 minutes until the sauce is bubbling and the cheese is golden.
- Finish with fresh basil leaves, a grind of black pepper, and crusty bread on the side for dunking.
Pro Tip: Virginie’s most-tested note on this one use hot stock, not cold, when you add it in step two. It keeps the oven temperature stable and helps the sauce come together faster.
Can You Make Baked Chicken Gnocchi Casserole Ahead of Time?
You can assemble most of it ahead, but the gnocchi is best baked fresh it can get a little dense if it sits in the sauce too long before cooking.

Note: Leftovers reheat well the next day with a small splash of chicken stock stirred in to loosen the sauce.
