Cooking pasta: Cook the tagliatelle according to the package instructions until al dente. Drain and set aside.
Preparing vegetables: Slice the mushrooms into thin slices. Cut the parsnip into eight thin wedges. Peeling is not necessary, just wash them well.
Sautéing vegetables: Heat the olive oil in a large frying pan over medium heat. Add the garlic and sauté briefly until fragrant.
Add the parsnip and mushrooms and sauté until they start to turn golden brown and soft (about 8-10 minutes).
Making the sauce: Deglaze the pan with the white wine and stir well. Let the wine reduce for 2-3 minutes.
Add the cream and let it simmer gently until the sauce thickens. Season with salt and pepper.
Combining: Add the cooked tagliatelle to the pan and mix everything well so that the pasta is coated with the creamy sauce.
Serving: Divide the pasta among the plates and garnish with fresh basil. Serve immediately.
Tips
For extra taste you can add some Parmesan cheese or roasted pine nuts as a topping. This dish combines well with a fresh green salad or a glass of white wine, such as Sauvignon Blanc. Do you want to make the dish vegan? Use vegetable cream and replace the tagliatelle with an egg-free variant.
