1-First Step: Mise en place and oven prep Preheat your oven to 375 degrees. Measure and prep all ingredients so the cooking flows smoothly: cut the cream cheese into small pieces, shred the Cheddar if needed, and have spices measured. Bring a large pot of salted water to a boil while you prep other items.

2-Second Step: Cook the pasta Add the dried spaghetti to the boiling salted water and cook according to package directions until al dente (usually 8 to 10 minutes). Drain the spaghetti, then return the pot to the stove. Keeping the cooked pasta in the pot makes the next steps easier and reduces dishes.

3-Third Step: Bloom the spices and coat the pasta Over medium-high heat, melt 4 tablespoons unsalted butter (or warm 4 tablespoons olive oil if using). Add 2 teaspoons Creole seasoning, 2 teaspoons garlic powder, 1 teaspoon dried thyme or oregano, 1 teaspoon freshly cracked black pepper, 1/2 teaspoon ground cayenne, and 1/2 teaspoon ground paprika. Stir and cook for about 30 seconds until fragrant. Immediately add the cooked pasta and toss to coat evenly with the spiced butter.

4-Fourth Step: Build the creamy sauce Pour in 3 cups whole milk and add the 4 ounces of cream cheese pieces. Stir gently over medium heat until the cream cheese melts and blends with the milk to form a smooth base. Once homogenous, add 1 cup shredded Cheddar and toss until it melts and the sauce thickly coats the noodles. Taste and season with additional kosher salt and freshly cracked black pepper if needed.

5-Fifth Step: Transfer and bake Arrange the creamy pasta evenly in an ovenproof pot or baking dish. Sprinkle with a little more Cheddar and a dusting of paprika for color. Cover the pot or dish and bake at 375 degrees for 20 minutes. After 10 minutes, remove the lid to let the top brown and develop a light crust. The last 10 minutes of uncovered baking will give the pasta a pleasing golden top.

6-Final Step: Finish and serve Remove the baked Creole tetrazzini from the oven and sprinkle with finely chopped parsley. Let cool for 5 minutes before serving so the sauce firms slightly and portions hold together. Slice or scoop into plates and pair with a crisp green salad or cornbread for a balanced meal.
