Mushroom and leek tetrazzini is the ultimate creamy, cheesy comfort that is sure to become a family favorite. Make-ahead friendly and adaptable, this pasta bake is worth adding to your weeknight repertoire. Mushroom and Leek TetrazziniQuestion: when does a plate of cheesy pasta ever not sound appealing? I’ve rediscovered my love for pasta lately after taking a bit of a hiatus (I was on a major farro and quinoa kick), and feel like I’ve been reconnected with my noodle-twirling roots.

Growing up Italian, my mom made homemade sauce, meatballs, and pasta every Tuesday night without fail. Her recipes never changed, but the excitement we felt for pasta night never dwindled. We twirled and slurped and sopped up any excess with fresh Italian bread and dispersed from the table with our hearts and bellies feeling full.Mushroom and Leek TetrazziniMushroom and Leek TetrazziniThis pasta bake may not have the same nostalgia factor, but the comforting nature of it feels fondly familiar—like a hug in a bowl.

Most tetrazzini’s include either chicken or turkey (which you could certainly include), but this meatless version feels every bit as meaty thanks to the addition of plump cremini mushrooms. Leeks add a sweeter, more delicate flavor than traditional onions, which compliment the deeply savory ‘shrooms beautifully.

You can amp up the creaminess by using either cream cheese or crème fraîche (I personally prefer the tang of the latter). Lemon zest and juice cut through the richness of the dish, which is brightened up by a final flurry of fresh parsley. Mushroom and Leek TetrazziniI hope this creamy, cheesy casserole brings you as much comfort and bliss as it’s brought me. It’s perfect for a cozy weeknight in, or for entertaining guests over the holidays. Serve with a hearty kale salad and some crusty bread and it’s like bringing the best of an Italian restaurant to the comfort of your own kitchen. Cheers!

    So good and so easy! I made this with chanterelles since we had some stashed in the freezer and increased the proportions a little since I had a 12 ounce box of Einkorn spaghetti. I couldn’t believe it had such a complex flavor for being so quick and easy

    This was SO GOOD and simple. I swapped normal pasta for Ancient Harvest corn and quinoa, and it turned out perfectly. This is the third or fourth recipe that I’ve made of yours, and all of them have been DELICIOUS!! Thank you thank you.
