Lasagna Stuffed Shells with Beef and Ricotta

Lasagna stuffed shells hold a beef, ricotta and spinach filling inside individual pasta cups. Marinara keeps the edges moist, while mozzarella forms a soft melted top. The shells are partly cooked before filling so they finish in the oven without collapsing. Prepare a few spare shells because some can tear in boiling water. Filling them with a small spoon is easier than forcing in too much at once. A short rest after baking lets the hot cheese and filling settle before you lift out portions.

Cover shells with remaining sauce and mozzarella. Cover with foil and bake 30 minutes, then uncover 10 minutes until bubbling and the centre reaches 74°C (165°F). Rest 10 minutes.

Helpful tips

• Boil a few spare shells.
• Leave pasta slightly firm.
• Cool beef before adding egg.

Troubleshooting

• This method requires partly boiled shells. Raw shells will not cook consistently with these amounts.
• Cool beef before adding egg.

Serving ideas

Substitutions

Ground turkey can replace beef; cook it to 74°C (165°F). Drain wet ricotta before mixing.

Variation

Use 250 g browned finely chopped mushrooms instead of beef for a meat-free version.

Make ahead

Assemble a day ahead and refrigerate; cold shells may need 10–15 minutes longer covered baking.

Storage and reheating

Refrigerate up to 3 days. Freeze cooled portions up to 2 months. Reheat covered with a little sauce to 74°C (165°F).

Food safety

Use clean utensils and wash produce. Keep perishable ingredients refrigerated at 4°C (40°F) or below. Refrigerate perishable leftovers promptly, within 2 hours, or within 1 hour above 32°C (90°F).
