This Tortellini Al Forno recipe has cheese-filled tortellini tossed in a rich and creamy garlic Alfredo sauce. It tastes just like Olive Garden's famous dish and is super easy to make!
Use kitchen shears to cut the bacon into 2-3 inch pieces so that they equally cover the pan and cook evenly.
In a large skillet, (preferably cast iron), cook the bacon slowly on low heat. *Low and slow is best for bacon*.
Once the bacon is nearly cooked and crisp on each side, cook the tortellini in a large pot according to package instructions. Set aside.
Remove the cooked bacon from the pan, set aside to cool, and leave 2 Tablespoons of bacon grease in the pan. Keep the heat on low and add the garlic to the pan, cooking for about one minute.
Increase the heat to medium. Gradually whisk in the flour, stirring constantly, until all flour is incorporated and the grease has thickened.
Gradually add the half and half (keep stirring). Bring the mixture to a boil and add the salt/pepper and Italian seasoning. Reduce the heat back to low and stir for about 2 more minutes.
Add the Parmesan, Asiago, and mozzarella cheeses. Stir until well incorporated and thick. Toss in the spinach and the Tortellini and use a rubber spatula to carefully incorporate it into the sauce.
Once the spinach has wilted (about 1 minute), turn off the heat. Crumble the cooled bacon into smaller pieces and sprinkle over the Tortellini. Serve and enjoy!
