Essential Ingredients & Shopping Advice
- Good mushrooms: Go for cremini or portobello for deeper flavor
- Young spinach: Get the fresh stuff for better bite than the frozen kind
- Regular flour: You'll need this for your creamy white sauce
- Full-fat milk: Makes the creamiest sauce possible
- Pasta sheets: Ready-to-use or regular both do the job
Step-By-Step Cooking Guide

- Cook mushrooms till golden brown, then toss in spinach and garlic until soft
- Master the sauce:
- Mix butter with flour, then slowly pour in warmed milk while stirring
- Add flavors:
- Sprinkle in nutmeg, salt, and pepper to boost taste
- Build your layers:
- Begin with thin sauce coating, then stack noodles, veggies, and cheese
- Stack with care:
- Make sure goodies are spread evenly across each layer

My nonna always told me to throw in a tiny bit of nutmeg to the white sauce - you can hardly taste it but it really makes the whole dish pop.
Prep Ahead Options
You can put everything together up to a day before, wrap it up and chill it. Just let it warm up on the counter before it goes in the oven.
Best Cheeses To Use
Mix fresh mozzarella with full-fat ricotta and aged Parmesan to get amazing flavor depth and that perfect gooey melt.
Getting Veggies Just Right
Don't crowd your mushrooms in the pan. Cook them in small batches so they brown nicely instead of steaming.
Perfecting Your Sauce
Pour warm milk bit by bit while stirring non-stop to keep your white sauce lump-free.
Pro Cooking Tricks
