Easy Cheesy Gnocchi Casserole Recipe | Creamy Baked Delight
I recently made this Easy Cheesy Gnocchi Casserole, and it was an absolute hit! The combination of pillowy gnocchi, sautéed mushrooms, and fresh spinach enveloped in a creamy, garlicky cheese sauce was simply irresistible.
What I love most is how quickly it comes together—just 20 minutes from start to finish. You can also enjoy similar creamy flavors in this Creamy Butternut Squash Gnocchi with Sausage, Thyme, and Sage Recipe, which makes a delightful alternative when craving comfort food.

Ingredients
- 1 packet (17.5 oz) potato gnocchi: These soft, pillowy dumplings cook quickly and absorb the cheesy sauce beautifully.
- 2 tablespoons olive oil: Used to sauté the garlic and mushrooms, adding flavor and helping them cook evenly.
- 4 cloves garlic, minced: Fresh garlic brings a rich, savory aroma that enhances the overall flavor of the dish.
- 8 ounces (227g) mushrooms, sliced: Mushrooms add a hearty, umami element, making the casserole feel satisfying without meat.
- 4 cups fresh baby spinach: Spinach adds color, nutrition, and a subtle, earthy flavor that balances the richness of the sauce.
- 1 cup heavy cream: Provides a luscious, velvety base for the cheese sauce.
- 1 cup shredded mozzarella cheese: Melts beautifully, creating a gooey, cheesy layer that binds everything together.
- 1/2 cup grated Parmesan cheese: Adds a sharp, nutty flavor that complements the mozzarella and enhances the overall taste.
- Salt and freshly ground black pepper, to taste: Essential for seasoning and bringing out the flavors of the ingredients.
Note: This recipe yields approximately 6 servings.
