- 1 lb (450g) potato gnocchi: The soft, pillowy foundation that soaks up all the delicious flavors beautifully.
- 1 lb (450g) Italian sausage, casings removed (optional): Adds a hearty, savory depth, but can be omitted for a vegetarian twist.
- 1 cup (240ml) marinara sauce: Brings a vibrant tomato tang that balances creamy elements.
- 1 cup (240ml) heavy cream: Infuses rich, velvety smoothness to the casserole.
- 2 cups (200g) shredded mozzarella cheese: Melts beautifully with a mild, stretchy texture.
- 1/2 cup (50g) grated Parmesan cheese: Offers a sharp, nutty counterpoint to mozzarella.
- 1 cup (150g) cherry tomatoes, halved: Burst of juicy sweetness and vibrant color.
- 2 cups (60g) fresh spinach: Adds freshness and a mild earthiness that balances richness.
- 3 cloves garlic, minced: Provides that aromatic punch that wakes up the whole dish.
- 1 tsp dried oregano: Classic herb for an Italian-inspired aroma.
- 1/4 cup (10g) fresh basil leaves, torn: Bright, fragrant finishing touch.
- Salt and pepper to taste: Essential for seasoning each layer perfectly.
- 2 tbsp olive oil: For sautéing and adding that subtle fruity richness.
How to Make Cheesy Baked Gnocchi Casserole Recipe
Step 1: Get Your Oven Ready
First things first, preheat your oven to 375°F (190°C). This ensures a hot and welcoming environment for your casserole to bake evenly and develop that irresistible golden crust.
Step 2: Prepare the Gnocchi
If you’re using shelf-stable gnocchi, they’re ready to go straight into the casserole. However, frozen gnocchi benefit from a quick boil to thaw and soften them just right, so check your package instructions and boil accordingly to keep that perfect texture.
Step 3: Sauté Garlic and Sausage
Heat olive oil in a large oven-safe skillet over medium heat. Toss in the minced garlic and sauté just until fragrant, about one minute to avoid any bitterness. Next, add the Italian sausage if you’re using it, breaking it up as it cooks until it’s beautifully browned and savory. This step builds a base of flavor integral to the dish.
Step 4: Mix the Creamy Sauce
In the same skillet, stir together the marinara sauce, heavy cream, and dried oregano. This creates a luscious, herb-infused sauce that ties all the ingredients together with creamy, tangy goodness.
Step 5: Layer the Ingredients
Now comes the fun part! Start by spooning a bit of the sauce mixture on the bottom, then add a layer of gnocchi, followed by fresh spinach, halved cherry tomatoes, cooked sausage, and a sprinkle of mozzarella and Parmesan. Repeat these layers until your skillet is full or your ingredients are completely used, creating a mosaic of flavors and textures in the pan.
Step 6: Finish with Cheese
Top your creation with a generous layer of mozzarella and Parmesan cheese. This final cheese blanket is what will bubble, brown, and bring that iconic baked appeal.
Step 7: Bake the Casserole
Pop your skillet in the oven and bake for 20-25 minutes until the cheese is bubbling and golden. For those who love a crispier finish, switch on the broiler for the last 2-3 minutes but watch carefully to avoid burning.
Step 8: Add Fresh Basil
Once out of the oven, sprinkle torn basil leaves on top. This fresh herbal brightness enhances every bite and adds an inviting fragrance.
Step 9: Let It Rest
Allow your cheesy masterpiece to rest for 5-10 minutes before serving. This resting period helps the casserole set, making it easier to serve and allowing the flavors to meld perfectly.
How to Serve Cheesy Baked Gnocchi Casserole Recipe

Garnishes
A sprinkle of freshly cracked black pepper or an extra handful of torn basil leaves adds a lovely fresh pop that complements the rich, cheesy layers. A drizzle of good-quality olive oil on the plate can also enhance the depth.
Side Dishes
This casserole stands beautifully on its own but pairs wonderfully with a crisp green salad to balance its richness. Garlic bread or a simple roasted vegetable medley also make lovely companions, rounding out the meal with additional textures and flavors.
Creative Ways to Present
For a fun twist, serve the casserole in individual ramekins for personalized portions, making it ideal for dinner parties. Alternatively, scoop portions onto plates and top with a fresh basil sprig for a restaurant-style presentation that impresses every time.
Make Ahead and Storage
Storing Leftovers
Leftover Cheesy Baked Gnocchi Casserole Recipe keeps well covered in the fridge for up to 3 days. Store it in an airtight container to preserve freshness and prevent any flavor transfer.
Freezing
This casserole freezes beautifully. Place cooled leftovers in a freezer-safe container, separating layers with parchment paper if desired, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
For the best texture, reheat leftovers in the oven at 350°F (175°C) until warmed through and the cheese is molten again, around 15-20 minutes. Microwaving works too, but the oven method keeps the top delightfully crispy.
FAQs
Can I make this casserole vegetarian?
Absolutely! Simply skip the Italian sausage and consider adding mushrooms or extra vegetables for added flavor and heartiness without missing the savory notes.
Do I need to boil the gnocchi before baking?
If you’re using pre-packaged shelf-stable gnocchi, no boiling is necessary. Frozen gnocchi should be boiled quickly as per package instructions to prevent a raw doughy texture after baking.
Can I use a different cheese instead of mozzarella?
Mozzarella is ideal for its melting quality and mild flavor, but you can substitute or mix in provolone, fontina, or even a bit of cheddar for a sharper taste.
How spicy is this recipe?
This casserole is generally mild, but if you enjoy a kick, add some red pepper flakes to the sausage while cooking or sprinkle them on top before baking.
Is the casserole freezer-friendly after baking?
It’s best to freeze the casserole before baking for optimal texture. If freezing after, be aware the cheese topping may lose some crispness upon reheating, but the dish will still taste delicious.
