I've spent the last 10 years learning to cook this baked macaroni and cheese the way my mom did when I was a kid. My first favorite food! You're Welcome.
Preheat oven to 325F degrees.
Bring a pot of water to a rolling boil, then add a lot of salt. You want it to be as salty as the ocean tastes. Add pasta and cook pasta to an al dente texture, usually about 7 minutes. Do not fully cook since pasta will cook more later in the oven.
Meanwhile – in a large mixing bowl, add eggs, seasoned salt, and pepper and whisk together. Add milk and whisk again. Set aside.
Drain pasta in a colander. Add butter to pot then return pasta to pot while still hot and mix until butter is completely melted.
Remove from oven and let rest for at least 15 minutes (or more) before serving.
