Sausage Pesto Tortellini Casserole is such an incredible, delicious and easy meal to make. Made with bright and wholesome ingredients, this dish comes together super quickly and lets you enjoy more time with your family. We are a busy family, but we still love to cook lots of homemade dinners to show our son how fun homemade dinners can be.

Tips and Tricks for the perfect Sausage Pesto Tortellini Casserole:

  • Start with fresh and quality pasta. I love using three-cheese tortellini as they are cheesy and delicious.
  • This recipe is really versatile, so you can totally use your favorite type of sausage. Since I was going for an Italian theme, I added Sweet Chicken Sausage.
  • To add some heat to the dish, use some spicy sausage and some red pepper flakes.
  • Use fresh ingredients. Adding fresh grape tomatoes and spinach, will brighten up your dish and add some juiciness and sweetness that will balance the cheese.
  • Use quality cheese, to save time I buy shredded cheese, but make sure it’s creamy and fresh.
  • Don’t overcook the tortellini! Cook it 1 or 2 minutes less than the recommended time as you will also have to bake it.
  • If you want to add more flavor you can add some minced garlic, fresh black pepper and top your casserole with fresh basil.

Do you bake then freeze? Or freeze assembled? And what's the reheat time?

Please don’t rate a recipe unless you have actually made it. Saying that a recipe “looks good” isn’t helpful to those of us looking for honest feedback on it.



What is a "package" of pesto? 8oz jar??
