Butter: ¼ cup (half a stick) of unsalted butter, completely melted to mix with the herb packet for the breathtaking final glaze.

Step by Step Instructions

Prep the Oven and Pasta: Preheat your oven to a massive 400°F (200°C) and lightly grease a 9×13 baking dish. Boil your spaghetti in heavily salted water according to the package directions until perfectly al dente. Drain well.

-
Mix the Biscuit Dough: In a large mixing bowl, gently combine the Cheddar Bay biscuit mix, shredded sharp cheddar cheese, and cold water. Stir gently until just combined. Do not overmix, or the biscuits will become highly dense!
-
Drop the Biscuits: Using a large spoon, drop massive, highly fluffy spoonfuls of the biscuit dough directly over the top of the hot spaghetti filling, spacing them out slightly so they can beautifully expand.

Frequently Asked Questions
Can I make this spaghetti casserole ahead of time? You can perfectly prepare the spaghetti and meat sauce mixture up to 24 hours in advance and store it tightly covered in the refrigerator! However, it is highly essential that you do not mix or drop the biscuit dough onto the cold pasta until the absolute second before you are ready to bake, so the dough bakes up perfectly fluffy.
Can I use ground turkey instead of ground beef? Absolutely! Lean ground turkey or mild Italian sausage are completely brilliant substitutions that will provide a breathtakingly savory flavor profile to the rich marinara sauce.
How do I store and reheat leftovers? Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. To perfectly restore the shatteringly crisp exterior of the biscuits without drying out the highly moist pasta underneath, reheat individual portions in the oven at 350°F or in an air fryer for a few minutes!
