Hello lovelies, when high summer makes the zucchini grow faster than we can eat them, we start rolling: this zucchini involtini with spinach and feta is my favourite recipe for using up several of the green giants at once. Thin zucchini slices go briefly into the oven, are then rolled around a warm spinach and feta filling and baked on a herby tomato sauce – light, summery and with no pasta or potatoes in sight.

The heart of the dish is the filling: I let fresh spinach wilt in the pan with onion and garlic, season it with a pinch of nutmeg and a splash of lemon juice and finally fold in the crumbled feta. This mixture goes spoonful by spoonful onto the pre-softened zucchini slices, which then roll up into little rolls without cracking.

Underneath sits a quick tomato sauce with oregano, basil and a little chili, in which the rolls soak up flavour beautifully as they bake. On top, grated parmesan and a few fresh basil leaves form the golden crust that holds the whole dish together.

What comes out of the oven is a dish that sits lightly on the plate yet still fills you up – perfect as a summery main with a little bread or as a starter for guests.

If you fancy more stuffed vegetable dishes, do try my Filled zucchini with lentils and orzo, my Stuffed peppers with spinach and my Vegan cannelloni with spinach, which are baked rolled up in tomato sauce just the same.

TIPS

Verena's notes

Tip from my kitchen: pre-bake the zucchini slices only until they bend easily – that way they won't tear when you roll them and the involtini keep their shape. Because zucchini releases so much water, I pat the slices dry after pre-baking if needed, which keeps the sauce nice and rich. I let the filling cool slightly before rolling so it is easier to spoon on. Leftovers taste almost better cold the next day as a starter.

INSTRUCTIONS

Pre-soften the zucchini

  1. Preheat the oven to 220 °C / 425 °F.
  2. Wash the zucchini and, using a sharp knife or vegetable peeler, slice lengthwise into thin strips about 2-3 mm thick.
  3. Lay the slices on a baking sheet, drizzle with olive oil, season lightly with salt and bake until soft and pliable.
  4. Remove the pre-softened zucchini slices and set aside.

Spinach and feta filling

  1. Wash the fresh spinach, drain and roughly chop. Peel and finely chop the onion and garlic.
  2. Heat 1 Tbsp olive oil in a pan and fry the onion and garlic until translucent.
  3. Add the spinach and let it wilt, then season with a pinch of nutmeg and a splash of lemon juice and adjust with salt and pepper.
  4. Take the pan off the heat, fold the crumbled feta through the spinach and let the filling cool slightly.

Tomato sauce

  1. Stir the chopped tomatoes together with the dried oregano, dried basil and chili flakes in a bowl and season with salt and pepper.

Roll and bake

  1. Spoon 1-2 tsp of the spinach and feta filling onto each pre-softened zucchini slice and roll the slice up into a little roll.
  2. Spread the tomato sauce in a baking dish and arrange the zucchini involtini snugly on top, seam side down.
  3. Sprinkle with grated parmesan and fresh basil.
  4. Bake in the preheated oven at 220 °C / 425 °F until the cheese is golden. Serve warm and enjoy.

Frequently asked questions

  • Slice the zucchini lengthwise into thin strips about 2-3 mm thick. A vegetable peeler or mandoline gives the most even results, but a sharp knife and a little patience work too. Evenly thin slices soften nicely in the oven and roll up without cracking.

  • No, as long as you do two things: pre-bake the zucchini slices briefly first, until they are pliable but still have a little bite, and pat them dry if needed. Zucchini holds a lot of water, so a short pre-bake draws out moisture and the rolls keep their shape after baking instead of turning soft.

  • Yes, it is a great make-ahead dish. Assemble the filled rolls in the tomato sauce the day before, cover and refrigerate, then bake just before serving. Add about 5-10 minutes to the baking time when it goes in straight from the fridge, until the cheese is golden.

  • Swap the feta for vegan feta (or seasoned, crumbled tofu) and the grated parmesan for dairy-free grated cheese or a handful of nutritional yeast. The spinach filling, the tomato sauce and the zucchini are already plant-based, so only those two ingredients need swapping.

  • Store leftovers covered in the fridge for about 2-3 days. Reheat the involtini in the oven at 180 °C / 350 °F so the surface stays crisp; the microwave makes them softer but still tastes good. They are also lovely cold as a summer starter or packed into a lunchbox.
