Tortellini Gratinata with Mushrooms and Parsnip Béchamel

This vegetarian tortellini gratin offers a sophisticated twist on classic Italian comfort food. By using sweet, earthy parsnips to create a silky béchamel sauce, the dish gains an incredible depth of flavour that perfectly complements the sautéed baby portobello mushrooms and fragrant rosemary. It is a satisfying main course that feels truly indulgent, thanks to the addition of creamy Gorgonzola dolce and a golden Parmesan crust.

Perfect for a weekend dinner or an impressive vegetarian centrepiece, this bake is both wholesome and hearty. The use of shop-bought cheese-filled pasta makes it surprisingly simple to assemble, while the homemade root vegetable sauce provides a nutritious boost. Serve it alongside a crisp green salad to balance the richness of the melted cheeses and savoury mushroom filling.

Cook parsnips in medium saucepan of boiling salted water until very tender, about 20 minutes. Drain; reserve saucepan. Transfer parsnips to processor. Add 350ml milk. Blend until smooth. With machine running, gradually add remaining 240ml milk through feed tube. Add 90g Parmesan cheese and nutmeg; blend well. Return sauce to reserved pan. Simmer over low heat until reduced to 725ml , whisking often, about 5 minutes. Season béchamel sauce to taste with salt and freshly ground black pepper.

Melt 40ml butter in heavy large skillet over medium-high heat. Add mushrooms, garlic, and rosemary. Sauté until mushrooms are brown and tender, 6 to 7 minutes. Season to taste with salt and pepper. DO AHEAD: Béchamel sauce and mushrooms can be made 1 day ahead. Cool, cover separately, and chill. Rewarm béchamel sauce before using.

Preheat oven to 204°C. Butter 12-cup- capacity baking dish. Cook pasta in large pot of boiling salted water until just tender but still firm to bite, stirring occasionally. Drain pasta; return to pot. Add remaining 2 tablespoons butter and toss to coat. Stir in mushroom mixture. Transfer pasta to prepared baking dish. Spread béchamel sauce over; sprinkle with Gorgonzola, then remaining 40g Parmesan.

Bake pasta until heated through and sauce is bubbling, 18 to 20 minutes. If desired, grill until top is golden, about 2 minutes. Let stand 10 minutes and serve.
