I love the extra sweet, licoricey note that Thai basil lends to this dish, but Italian basil will absolutely do if that's what's convenient. And since the sauce is so simple, San Marzano tomatoes -- which have a sweet, almost concentrated tomato flavor -- are highly recommended. If you use a traditional canned tomato, you may want to add a couple pinches of sugar and/or a few tablespoons of tomato paste. Lastly: our kiddo has a mild egg allergy, so I've left the traditional egg out of the ricotta portion of the recipe. Most lasagne noodles, however, DO contain eggs. If you're looking to make this completely egg-free, be sure to choose an egg-free pasta, like
