Step 1

Preheat your oven or pellet grill to 325°F.

Step 2

Parboil the jumbo shells following the boxed instructions. Only cook them for half the time called for on the box, however. When finished, rinse with cold water and set aside.

Step 3

Mix together the cheese mixture ingredients until well combined. Set aside.

Step 4

If making homemade sauce, make that now. If you are using store-bought sauce, brown the ground beef in a large sauce pot. Add the jarred sauce and let heat over medium heat, stirring frequently.

Step 5

In a 10x13 high-sided baking dish, spoon in a couple of cups of sauce.

Step 6

Fill each shell with the cheese filling mixture and place into the pan with the sauce. Repeat until they are all filled. You may have a few extra shells. That's normal.

Step 7

Cover with the rest of the pasta sauce. Top with the mozzarella from the cheese topping part of the ingredient list, and sprinkle with Italian seasoning.

Step 8

Bake for 45 minutes to 1 hour, or until everything is hot, bubbly, and the internal temp of the cheese stuffed into the shells is as least 160°F.

Step 9

Let cool for 10 minutes on a heat-resistant surface before serving.

Step 10

Serve with crusty bread and salad.
