- Step 2. Cook the tortellini and once done drain it.

TIP: The pesto does not need to be cooked, so all you need to do is toss it in and serve warm.

To warm it up again, bear in mind that the pesto is not meant to be cooked.
- Step 1. Heat up a large sauté pan with butter or olive oil over low heat.
- Step 2. Add the pasta (you may need to batch warm it up, depending on how much you have leftover).

Lori says
Can I make this dish a day ahead and bake the day I serve it
Shinee says
Hi, Lori. I’ve never tried making this dish that way. My only concern is that the pasta may dry out during baking, since this dish isn’t saucy.
