Ingredients You’ll Need

This Cheesy Baked Gnocchi Casserole Recipe relies on simple but crucial ingredients that create a symphony of flavors and textures. Each component plays its part in making the dish creamy, cheesy, and full of vibrant color that’s as pleasing to the eye as it is to the palate.

Potato gnocchi (1 lb / 450g): The soft, pillowy star that soaks up all the sauce beautifully.
Italian sausage (1 lb / 450g, optional): Adds a savory, slightly spicy depth but can be omitted or substituted.
Marinara sauce (1 cup / 240ml): A tangy tomato base that brings acidity and richness.
Heavy cream (1 cup / 240ml): Makes the sauce decadently creamy and smooth.
Mozzarella cheese (2 cups / 200g, shredded): Perfect for that gooey, melty cheese pull.
Parmesan cheese (1/2 cup / 50g, grated): Adds a nutty, salty punch.
Cherry tomatoes (1 cup / 150g, halved): Burst of freshness and slight sweetness.
Fresh spinach (2 cups / 60g): Gives color and a mild, earthy flavor.
Garlic (3 cloves, minced): Infuses a warm, aromatic undertone.
Dried oregano (1 tsp): Brings an herbaceous note that complements the sauce.
Fresh basil leaves (1/4 cup / 10g, torn): Added at the end for a bright, fragrant finish.
Salt and pepper: To taste, essential for balancing all flavors.
Olive oil (2 tbsp): The foundation to sauté garlic and sausage with a touch of richness.

How to Make Cheesy Baked Gnocchi Casserole Recipe

Step 1: Preheat and Prep

Start by setting your oven to 375°F (190°C) so it’s ready when your casserole goes in. If you’re using frozen gnocchi, give them a quick boil just until they float to the surface; this ensures they’ll be perfectly tender after baking. Shelf-stable gnocchi can go straight into the skillet without cooking.

Step 2: Sauté Aromatics and Sausage

Heat the olive oil in a large oven-safe skillet over medium heat. Toss in the minced garlic and let it sizzle for about a minute until fragrant but not browned. Then add in the Italian sausage, cooking until it’s nicely browned and cooked through. This step builds a savory base that infuses the entire casserole with heartiness.

Step 3: Create the Creamy Sauce

In the same skillet—no need to dirty another pan—pour in the marinara sauce and heavy cream, stirring in the dried oregano. This combination creates a luscious sauce that blends tangy tomato flavors with smooth creaminess, perfect for coating every bite of gnocchi later on.

Step 4: Layer Your Casserole

Now comes the fun part: layering! Start by spreading a little of the sauce on the bottom of the skillet. Then add a layer of gnocchi, followed by fresh spinach, cherry tomatoes, the cooked sausage, and a generous sprinkle of mozzarella and Parmesan. Repeat these layers until you’ve used all the ingredients or filled the skillet to the brim, making sure each layer is rich and balanced.

Step 5: Top and Bake

Finish the casserole with a thick layer of shredded mozzarella and Parmesan cheese to go on top. Bake the whole dish in your preheated oven for 20 to 25 minutes, until the cheese has melted into a bubbly, golden crown. If you’re craving extra crunch, pop it under the broiler for a couple more minutes—but watch it closely so it doesn’t burn!

Step 6: Garnish and Rest

Once baked, sprinkle torn fresh basil leaves over the casserole for a wonderful herbaceous aroma and burst of color. Let it rest for 5 to 10 minutes before serving—this helps the casserole set slightly, making it easier to portion and enhancing the overall richness.

Garnishes

A few simple garnishes can elevate your Cheesy Baked Gnocchi Casserole Recipe beautifully. Fresh basil is a classic choice that adds a pop of herbal brightness right before serving. If you’re feeling adventurous, try a drizzle of high-quality olive oil or a sprinkle of red pepper flakes for a subtle kick. A few shavings of extra Parmesan always make for a sophisticated finish.

Side Dishes

This casserole is pretty hearty on its own, but pairing it with a crisp green salad or roasted vegetables adds a lovely contrast in texture and freshness. Garlic bread or crusty baguette slices are perfect for scooping up any leftover sauce, ensuring nothing delicious goes to waste. For something lighter, steamed broccoli or a simple arugula salad dressed with lemon juice and olive oil complements the richness perfectly.

Creative Ways to Present

Want to impress your guests or family? Serve this casserole in individual oven-safe ramekins for personalized portions. This not only looks charming but also makes sharing easier and less messy. Alternatively, bake the casserole in a deep-dish and let everyone serve themselves family-style, encouraging conversation around the table. For a rustic twist, consider topping with toasted breadcrumbs mixed with Parmesan before baking to add an irresistible crunchy layer.

Make Ahead and Storage

Storing Leftovers

Leftover Cheesy Baked Gnocchi Casserole Recipe is a dream to enjoy later. Once it has cooled to room temperature, cover tightly with plastic wrap or transfer to an airtight container and store in the refrigerator for up to 3 days. The flavors meld even more after resting, making your next meal just as delightful.

Freezing

This casserole freezes beautifully, making it an excellent make-ahead meal option. After assembling but before baking, wrap the casserole dish tightly with plastic wrap and then aluminum foil to prevent freezer burn. Freeze for up to 2 months. When you’re ready to enjoy, thaw overnight in the refrigerator before baking as usual, adding a bit of extra bake time since it starts cold.

Reheating

To reheat leftovers, the oven is your best friend for preserving that cheesy casserole texture. Cover with foil and bake at 350°F (175°C) until warmed through—usually about 15-20 minutes. For quicker reheating, microwave portions covered loosely with a microwave-safe lid, but be mindful that the cheese won’t stay as melty as when baked.

FAQs

Can I make this casserole vegetarian?

Absolutely! Simply leave out the Italian sausage or substitute it with plant-based sausage or a mix of sautéed mushrooms and lentils to keep the dish hearty and satisfying without meat.

What type of gnocchi is best for this recipe?

Fresh or shelf-stable potato gnocchi works wonderfully. If using frozen, just give them a quick boil first to ensure they cook through nicely in the casserole without becoming gummy.

Can I use a different type of cheese?

While mozzarella and Parmesan are classic for their melt and flavor, you can experiment with provolone, fontina, or even cheddar blends for a different twist—just be mindful of meltability and taste balance.

Is it possible to prepare this recipe in advance?

Yes, assembling in advance is a great time-saver. Layer everything and keep the casserole covered in the refrigerator for up to 24 hours before baking, making dinner prep quick and easy.

How do I get a crispy cheese topping?

For a golden, crunchy cheese crust, finish baking with the broiler on for 2-3 minutes while watching carefully to avoid burning. You can also mix a bit of breadcrumbs into the cheese topping before baking for extra texture.
