If Julia Child were still with us, no doubt she would heartily approve of “Sage and Walnut Tagliatelle.”

This simple pasta dish, egg noodles get coated in plenty of browned butter infused with sage leaves turned crisp and aromatic, and tossed with crunchy toasted walnuts.

The recipe is from the new “Old World Italian: Recipes and Secrets from Our Travels in Italy” (Clarkson Potter), of which I received a review copy.

The book is by Mimi Thorisson, a former model — yes, apparently not all models subsist on only mineral water and chia seeds. The creator of the food blog Manger, she lives in France with her photographer-husband (who took the winsome photos for the cookbook) and their young children.

This transportive book will make you wish you were staying in a pensione right now, and exploring all the local trattorias — or best yet, having a nonna cook for you such mouth-watering dishes as Thorriso’s versions of “Oven-Baked Eggs with Bottarga and Parsley,” “Pumpkin Ravioli with Brown Butter, Chestnut, and Sage,” “Roast Pork with Balsamic Vinegar and Red Wine,” and “Lemon Meringue Cake.”

What I love about this pasta dish is that it comes together in minutes and doesn’t require a special trip to the grocery store, especially if you have a well-stocked pantry, and grow sage in your yard like I do.
