Creamy Spinach Ricotta Stuffed Shells Recipe
Ingredients
- 2 tbsp olive oil
- 2 shallots (, finely chopped)
- 4 garlic cloves (, finely minced)
- 1 bay leaf (, fresh)
- 1/2 tsp dried thyme
- 1/2 tsp dried oregano
- 1/3 cup tomato paste
- 700 g / 25 oz tomato passata
- 1/3 cup dry white wine
- 4 cups vegetable stock, low sodium
- 3/4 tsp salt
- 15 oz ricotta cheese
- 1/2 cup grated Parmesan cheese
- 1 large egg
- 1/4 tsp nutmeg
- 1 lb jumbo pasta shells
- 10 oz fresh spinach, squeezed dry
Instructions
- Heat olive oil in a pot over medium-high heat. Add shallots and garlic. Cook for 3-4 minutes until shallots are translucent.
- Stir in tomato paste and cook for 1 minute until fragrant.
- Add white wine, increase heat to high, and let it simmer rapidly until mostly evaporated (about 2 minutes).
- Pour in tomato passata, vegetable stock, and salt. Stir, then simmer uncovered on low heat for 20 minutes.
- Squeeze fresh spinach firmly to remove as much excess water as possible.
- In a bowl, combine the squeezed spinach with ricotta cheese, Parmesan cheese, egg, nutmeg, salt, and pepper. Mix well.
- Spoon the ricotta-spinach filling generously into each cooked pasta shell.
- Arrange the stuffed shells in a baking dish over a layer of the prepared tomato sauce. Top with remaining sauce. Bake at 200°C (400°F) for 20-25 minutes.
Notes
– For a smoother sauce, blend the passata before simmering.
– Add a pinch of sugar to the sauce to balance the acidity of the tomatoes.
– To make ahead: Assemble shells in sauce, cover, and refrigerate up to 24 hours. Bake an extra 5-10 minutes. Nutrition information is an estimate, calculated automatically. Values vary with brands, substitutions and portion sizes.
The technique that makes it
The success of these stuffed shells hinges on a few key techniques. First, properly cooking the jumbo shells is crucial. They should be al dente, meaning cooked through but still firm to the bite, as they will continue to cook in the oven. Overcooked shells will become mushy and lose their structural integrity when stuffed and baked. Secondly, the spinach must be thoroughly squeezed dry. Excess moisture from the spinach can make the ricotta filling watery, leading to a less cohesive and potentially soupy dish. Sautéing the aromatics – shallots and garlic – until softened and fragrant before adding the tomato paste deepens their flavor and removes any raw bite, creating a more complex sauce base. Deglazing the pan with white wine allows the alcohol to evaporate, leaving behind concentrated flavor that enriches the sauce. Finally, ensuring the ricotta filling is well-seasoned with salt, Parmesan, nutmeg, and egg before stuffing provides a rich, savory, and creamy counterpoint to the bright tomato sauce and tender pasta.
Troubleshooting
- Problem: Shells are undercooked or falling apart. Fix: Ensure shells are cooked to al dente according to package directions. For undercooked shells, bake for an additional 5-10 minutes, covered. If shells are falling apart, they were likely overcooked initially; try cooking them 1-2 minutes less next time.
- Problem: Filling is too watery. Fix: Squeeze the cooked spinach extremely dry. If the filling is still too wet, you can add a tablespoon or two more of ricotta or a bit of breadcrumbs to absorb excess moisture.
- Problem: Sauce is bland. Fix: Taste and adjust seasoning before baking. Add more salt, pepper, or a pinch of red pepper flakes for heat. A splash more white wine or a touch of sugar can also balance flavors.
- Problem: Stuffed shells are dry. Fix: Ensure the shells are generously covered with sauce, and that there’s enough liquid in the sauce itself. Adding a bit more passata or stock to the sauce can help. Cover the dish tightly with foil during the initial baking phase to trap steam.
Substitutions
- Ricotta Cheese: If ricotta is unavailable, you can substitute with an equal amount of drained cottage cheese (full-fat recommended for best texture) or a mixture of mascarpone and a little sour cream for a richer filling. The texture will be slightly different but still delicious.
- Jumbo Pasta Shells: Manicotti or large conchiglie (large shells) can be used instead of jumbo shells. If using manicotti, they are often baked unfilled and the filling is served alongside or on top. Large conchiglie will behave very similarly to jumbo shells.
- Fresh Spinach: Frozen spinach, thawed and thoroughly squeezed dry, is a convenient substitute for fresh. Ensure you use about half the amount of frozen spinach as fresh, as it’s more concentrated.
- White Wine: For an alcohol-free version, substitute the white wine with an equal amount of vegetable stock or a splash of white wine vinegar mixed with water. The flavor depth will be slightly altered but still enjoyable.
Pro tips
- Squeeze that spinach DRY! Excess water will make the filling watery.
- For a smoother sauce, blend the passata before simmering.
- Add a pinch of sugar to the sauce to balance the acidity of the tomatoes.
- To make ahead: Assemble shells in sauce, cover, and refrigerate up to 24 hours. Bake an extra 5-10 minutes.
Enjoy these delightful stuffed shells, a timeless classic that never fails to impress. Serve with a side salad and garlic bread for a complete meal.
