Preparation: Preheat the oven to 180°C. Peel the butternut squash and parsnip and cut into pieces. Clean the tomatoes, celery, onion, and garlic and chop everything finely. Strip the leaves from the thyme.
Vegetable puree: Cook the pumpkin and parsnip in salted water until tender (15–20 min). Drain and mash with a potato masher until smooth.
Tomato sauce: Sauté onion and garlic in 1 tbsp olive oil until translucent. Add tomato paste and cook briefly. Add tomatoes, celery, milk, thyme, pepper, salt, and nutmeg. Let simmer for 10 minutes. Blend smooth with an immersion blender.
Minced meat (or lentils): Sauté the veal mince (or lentils for the veggie version) with a bit of olive oil and extra garlic for 5 minutes.
Make filling: Mix the vegetable puree with ricotta and the cooked minced meat (or lentils).
Fill cannelloni: Use a piping bag (or a freezer bag with a snipped corner) to fill the cannelloni with the mixture. Place a layer of sauce in a baking dish, arrange the filled cannelloni on top, and cover with sauce. Repeat if necessary with a second layer of cannelloni and sauce. Finish with grated cheese.
Oven: Bake for 30 minutes in the preheated oven until the cheese is golden brown.
Serving: Serve with a fresh salad of lamb's lettuce or endive.
Tips
- No piping bag? Use a freezer bag with a snipped corner or roll the filling in lasagna sheets.
- Add extra vegetables, such as carrot or zucchini, for more variety.
- You can prepare the sauce in advance and freeze it.
- Use whole grain cannelloni for extra fiber.
- Prepare the dish in advance and store it covered in the refrigerator.
