Pumpkin and Red Lentil Monster Pasta Shells

Large stuffed pasta shells make a generous baked dinner, each holding a soft centre above tomato sauce. This Halloween version uses pumpkin and red lentils for a gently sweet, earthy filling lifted by sage. The lentils become a thick mash, while sauce keeps the pasta moist in the oven. Mozzarella and olive eyes sit on the open tops, added near the end so they stay recognisable. Inspired by Italian stuffed pasta, these modern little monsters are mild enough for a family meal and substantial enough for a main dish.

Why this recipe works

  • Lentils form a soft, cohesive filling: Red lentils soften into a thick mash that gives the pumpkin filling body. Evaporating excess water helps it stay inside the open shells.
  • Tomato brightens the pumpkin: Garlic tomato sauce brings a gently sharp, savoury layer beneath the sweeter filling. It also keeps the pasta moist during the covered bake.
  • Individual shells are easy to portion: The filled shells lift out individually with their sauce. Their open tops keep the cheese and olive faces visible as you serve.

Ingredient notes

  • Choose jumbo stuffing shells: Use the jumbo shells described in the ingredient note. Small pasta shapes cannot hold the same filling or leave room for an eye on top.
  • Use plain pumpkin purée: Sweetened pie filling would add sugar and dessert spices. Choose the plain pumpkin purée specified.
  • Use low-moisture mozzarella: Low-moisture mozzarella releases less liquid than fresh mozzarella in brine. Small, flat pieces settle onto the filling during the brief final bake.

Texture tips

  • Leave the pasta slightly firm: Shorten the initial boil as directed because the shells finish cooking in sauce. Separate gently after draining to prevent sticking and tearing.
  • Look for a filling that holds a mound: The lentil-pumpkin mixture should mound on a spoon. Evaporate excess moisture before stuffing, stirring so it does not catch on the pan.
  • Cover the first baking stage: Use the foil covering for the first bake, as directed. It holds moisture around the pasta before the brief uncovered stage softens the cheese eyes.

Timing notes

  • Finish the filling before boiling the shells: Thicken the filling first, then let it cool slightly while the shells boil. This avoids leaving cooked pasta waiting and sticking together.
  • Add the eyes near the end: Add cheese and olives for the final uncovered bake. Prolonged baking can melt the eyes into the sauce instead of just softening them.

Serving ideas

  • Spoon sauce around the faces: Lift the shells onto shallow plates and spoon tomato sauce around them. Leave the orange filling and the cheese-and-olive eyes uncovered.
  • Keep children’s portions practical: Show the finished faces, then cut olives smaller for young children. Let the filling and sauce cool to a comfortable eating temperature before serving.

  1. Rinse the lentils and put in a saucepan with the measured water. Bring to the boil, then simmer for 18–20 minutes, stirring towards the end, until soft and thick; let any excess water evaporate without scorching.
  2. Reserve 0.5 teaspoon salt for the sauce and stir the remaining salt into the lentils with the pumpkin, sage and pepper. Cook for 3–4 minutes until thick enough to mound on a spoon, then set aside to cool slightly while preparing the shells.
  3. Heat the oven to 190°C (375°F). Boil the shells in a large pan of water for 2 minutes less than the packet time, then drain, rinse briefly with cool water and separate carefully.
  4. Finely chop the garlic and warm it in the oil over a medium-low heat for 30 seconds until fragrant, without letting it brown. Add the passata and reserved salt, simmer for 8 minutes and spread in a 30 × 20 cm baking dish.
  5. Spoon the thick filling into the 20 shells and nestle them open-side up in the sauce. Cover loosely with foil and bake for 20 minutes, then uncover.
  6. Cut the mozzarella into 20 small flat pieces and halve the olives lengthways. Place a cheese piece and an olive half on each exposed filling, then bake uncovered for 5–8 minutes until the cheese just softens and the centre of the filling reaches 74°C (165°F).
  7. Rest for 5 minutes before serving, spooning tomato sauce around the shells without covering the eyes. Let children’s portions cool to a comfortable eating temperature.

Recipe notes

Tips

  • The lentil-pumpkin filling must be thick before stuffing; a watery mixture slips out of the shells. Cut olive pieces smaller for young children after showing them the decorated dish.
  • Use a large saucepan of at least 4 litres for boiling the shells and a baking dish about 30 × 20 cm and 5 cm deep. Serve on shallow plates with the sauce underneath so the eyes stay visible.

Substitutions

  • Replace the dried sage with dried oregano in the same quantity.

Storage

  • Refrigerate up to 2 days
  • Refrigerate in a covered container within 2 hours at 4°C (40°F) or below and use within 2 days. Reheat covered until the centre reaches 74°C (165°F), adding a small splash of water to the sauce if needed. If leftover shells break, reheat them with their sauce as a small pasta bake, following the same temperature and storage guidance; the cheese eyes may merge as they melt.
