Method
Prep and preheat
- Preheat your oven to 350F, then butter a deep 9x13 baking dish so the custard releases easily.
Build the custard
- Whisk eggs, whole milk, evaporated milk, Dijon mustard, smoked paprika, garlic powder, cayenne, salt, and pepper until fully combined and smooth.
Layer and assemble
- Layer half the cooked macaroni in the baking dish in an even spread.
- Scatter 2 cups cheddar, all the Colby Jack, and Gruyere over the macaroni.
- Add the remaining macaroni on top to create a second layer.
- Pour the egg-milk custard over everything so it seeps through the pasta.
- Dot the surface with butter cubes, then top with the remaining 2 cups cheddar for a browned crust.
Bake and rest
- Bake at 350F for 40-45 minutes, until the custard is set and the top turns golden and bubbly.
- Rest for 10 minutes before serving so the interior thickens into a custard-style slice.
Notes
For the cleanest scoop, bake until the center looks set with only a slight wobble, then rest the full 10 minutes. Store leftovers covered in the refrigerator up to 4 days; reheat in a 325F oven or microwave until steaming. Freezing is not recommended because the custard texture can turn grainy. For a lighter option, use reduced-fat cheddar and a 2% milk swap for part of the dairy.
