Tips for the Best Creamy Beef Shells Casserole

✔ Cook Pasta to Al Dente – The pasta will continue cooking in the oven, so don’t overcook it on the stovetop.
✔ Use Freshly Shredded Cheese – It melts better and gives a smoother texture to the casserole.
✔ Add Veggies – Stir in spinach, mushrooms, or bell peppers for extra nutrients.
✔ Don’t Skip the Sausage – It adds depth and flavor that pairs perfectly with the creamy sauce.
✔ Make It Spicy – Add red pepper flakes or a pinch of cayenne for a kick.

Recipe Variations and Substitutions

Make It Lighter – Use ground turkey or chicken instead of beef, and substitute heavy cream with half-and-half.
Add More Veggies – Toss in zucchini, spinach, or diced bell peppers for extra flavor and nutrition.
Use a Different Pasta – Try penne, rigatoni, or farfalle instead of shells.
Make It Gluten-Free – Use gluten-free pasta and ensure the tomato sauce is gluten-free.
Add a Crunchy Topping – Sprinkle breadcrumbs or crushed crackers on top before baking.
