I love how the Colby Jack cheese melts into the filling giving each shell a little extra gooey richness It reminds me of cozy evenings when my family would scrape every last bit of cheese from the dish and joke about who ate the most shells

Storage Tips

Let leftovers cool completely before covering and storing in the refrigerator Use an airtight dish and they will keep for up to four days For longer storage cover the dish tightly with foil and freeze for up to three months To reheat bake covered at three hundred fifty degrees until warmed through

Ingredient Substitutions

You can swap in any vegetables your family likes Bell peppers squash or kale work well Ricotta cheese can stand in for the cottage cheese and if you are dairy free try vegan Alfredo and cheeses

Serving Suggestions

Serve hot from the oven with a crisp green salad and garlic bread For a heartier meal pair with roasted chicken or a tangy tomato salad The shells are rich so something fresh and acidic is a nice balance
