Prep the Cheese & Pasta
- Grate all the cheeses. Leave them at room temperature; do not put them back in the fridge.
- Cook the pasta in well-salted water, following the package instructions but for 2 minutes less than the recommended time (it will finish cooking in the oven). Drain thoroughly.
Sauté Aromatics & Make the Roux
- Mince the garlic cloves.
- In a large pot over medium-low heat, melt the butter and cook the garlic until fragrant, being careful not to burn it.
- Add the flour and cook, stirring constantly with a spatula or whisk, until you have a light “blonde roux.” Do not let it brown.
Create the Cheese Sauce
- Whisk in the evaporated milk and heavy cream until smooth.
- Add the Dijon mustard, salt, black pepper, white pepper, smoked paprika, onion powder, and garlic powder.
- Keep stirring until the sauce thickens slightly.
Melt the Cheese & Combine
- Turn off the heat. Add the grated cheeses in two parts, reserving a handful for the top. Stir until the sauce is completely smooth and the cheese is fully melted.
- Taste the sauce and adjust seasoning if needed.
- Add the cooked, drained pasta to the pot and stir until evenly coated.
Assemble and Broil
- Preheat your oven’s broiler (grill) setting.
- Transfer the mac and cheese to an oven-safe dish. Sprinkle the reserved cheese evenly over the top.
- Place the dish under the broiler until the top is golden brown and bubbly. This can take anywhere from 2 to 10 minutes, so watch it closely to prevent burning.
Serve
- Let it cool for a few minutes before serving. Garnish with fresh parsley if desired. Enjoy!
