Why You’ll Love This Recipe
- Big flavor with simple ingredients: Italian sausage, garlic, parmesan, and sun-dried tomatoes do most of the work.
- Cozy texture: Soft potato gnocchi bakes in a rich cream sauce until every bite feels creamy and hearty.
- Easy prep: You brown the sausage, stir the sauce together, add cheese, and bake.
- Family friendly: Use mild sausage for a softer flavor or hot sausage if you like heat.
Fabian’s Budget Tip: Use bulk Italian sausage instead of links when you can. It often costs less, browns faster, and spreads through the casserole better. If links are on sale, remove the casing and cook the meat the same way.
Ingredients (Serves 4)
- 1 pound Italian sausage, mild or hot (454 g)
- 16 ounces potato gnocchi (454 g)
- 1/2 cup drained sun dried tomatoes, chopped (75 g)
- 3 packed cups baby spinach (90 g)
- 4 garlic cloves, minced (12 g)
- 1 teaspoon Italian seasoning (2 g)
- 1 1/4 cups heavy cream (300 ml)
- 1/2 cup grated parmesan cheese (50 g)
- 1 cup shredded mozzarella cheese (115 g)
- 1/2 teaspoon fine salt (3 g), plus more to taste
- 1/4 teaspoon black pepper (1 g)
Step-by-Step Instructions
1. Heat the Oven
Set the oven to 400°F (200°C). Keep a 9-by-13-inch baking dish nearby, or use a large oven-safe skillet if you have one.
2. Brown the Sausage
Place a large skillet over medium-high heat. Add the Italian sausage and break it into small crumbles with a spoon. Cook for 6 to 8 minutes, until the sausage sizzles, the edges turn golden brown, and the pan smells rich and savory.
3. Add Garlic, Tomatoes, and Seasoning
Stir in the minced garlic, Italian seasoning, sun-dried tomatoes, salt, and black pepper. Cook for about 1 minute. Stop when the garlic smells sweet and warm, not sharp or burnt.
4. Make the Creamy Sauce
Pour in the heavy cream and scrape the browned bits from the bottom of the pan. Let the sauce gently bubble for 2 to 3 minutes. Stir in the parmesan until it melts and the sauce looks glossy.
5. Fold in the Gnocchi and Spinach
Add the potato gnocchi and spinach. Stir until the gnocchi is coated and the spinach starts to wilt into the sauce. The sauce should look a little loose at this point because it thickens as it bakes.
6. Add Mozzarella and Bake
If your skillet is not oven safe, transfer the mixture to the baking dish. Sprinkle the mozzarella evenly over the top. Bake for 18 to 22 minutes, until the edges bubble and the cheese has golden spots.
7. Rest Before Serving
Let the casserole rest for 5 minutes. The sauce will settle around the gnocchi, and each spoonful will hold together better.
Expert Troubleshooting and FAQs
Do I need to boil the gnocchi first?
No, packaged potato gnocchi can go straight into the creamy sauce. It softens as the casserole bakes. If you use frozen gnocchi, thaw it first so the sauce does not turn watery.
Why did my sauce get too thick?
The parmesan and gnocchi both thicken the sauce. If it looks too thick before baking, stir in a small splash of cream or hot water until it looks glossy and loose again.
Can I use a different sausage?
Yes. Mild Italian sausage gives a classic flavor. Hot Italian sausage adds spice. Chicken or turkey sausage also works, but the casserole will taste a little lighter.
Can I make this casserole ahead of time?
Yes. Assemble it, cover it, and refrigerate it for up to 24 hours. Bake it straight from the fridge and add 8 to 10 extra minutes, until the center bubbles.
How do I store leftovers?
Store leftovers in a covered container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave. Add a spoonful of cream or water if the sauce tightens.
