My nonna always told me to add a tiny bit of nutmeg to the white sauce - you can't quite taste it, but it really brings out all the other flavors.
Prep Ahead Options
Put everything together up to a day ahead, keep in the fridge covered. Let it sit out for a bit before it goes in the oven.
Picking Your Cheeses
Mix fresh mozzarella with whole milk ricotta and aged Parmesan to get rich flavors and that perfect gooey stretch.
Handling Your Veggies
Don't crowd mushrooms in the pan or they'll steam instead of getting that nice brown color and flavor.
Nailing The Sauce
Pour warm milk in slowly while you stir non-stop to keep your béchamel smooth and lump-free.
Pro Kitchen Secrets
- Add fresh herbs between each layer
- Get mushrooms nice and brown before adding the spinach
- Let it cool a bit for clean-cut pieces

Recipe FAQs
- → Is it okay to prep this dish ahead?
- Totally fine! Build it up to a day before and refrigerate. If baking cold, just give it 10-15 extra minutes.
- → Can I freeze leftovers?
- Yep! Wrap it up and freeze for up to three months. Let it thaw in the fridge overnight when you're ready to use it.
- → Not a fan of mushrooms—what can I use instead?
- Swap mushrooms for roasted peppers, zucchini, or eggplant. Any of those would work great!
- → Do I have to cook the pasta first?
- Depends on your pasta! If it's no-boil, pop it in dry. Regular noodles need to be cooked beforehand.
- → How do I stop my sauce from lumping up?
- Warm up your milk first and add it slowly while whisking non-stop. That should do the trick!
