Ingredients:
- 12 oz Elbow Macaroni (or similar short shape)
- 4 Tbsp Unsalted Butter
- 4 Tbsp All-Purpose Flour
- 3 cups Whole Milk (room temperature)
- 1 cup Canned Pumpkin Purée
- 1 tsp Salt (plus extra for boiling water)
- 1/2 tsp Freshly Ground Black Pepper
- 1/8 tsp Ground Nutmeg
- 1/4 tsp Cayenne Pepper (Optional)
- 7 oz Sharp Cheddar Cheese (freshly grated)
- 5 oz Gruyère or Monterey Jack Cheese (freshly grated)
Instructions:
- Boil the Pasta: Bring a large pot of heavily salted water to a rolling boil. Add the macaroni and cook 1 minute less than package directions—we want it truly al dente.
- Drain and Reserve: Before draining, scoop out about 1 cup (240 ml) of the starchy cooking water and set it aside. Drain the pasta immediately and set aside.
- Prepare the Roux: Melt the butter in the heavy-bottomed saucepan over medium heat until foamy. Sprinkle in the flour, whisking continuously for 1 to 2 minutes until the roux takes on a pale blonde colour and smells slightly nutty.
- Introduce the Milk (The Béchamel): Slowly stream in the room-temperature whole milk, whisking constantly to prevent lumps from forming.
- Thicken: Increase the heat to medium-high and bring the mixture to a gentle simmer, whisking occasionally. Once the sauce coats the back of a spoon thickly (about 5-7 minutes), reduce the heat to low.
- Add Pumpkin and Seasoning: Whisk in the canned pumpkin purée until fully incorporated. Stir in the salt, pepper, nutmeg, and cayenne. Let simmer gently for 1 minute to heat through.
- Temper the Cheese: Crucially, remove the saucepan completely from the heat. Add the grated cheese in three batches, stirring thoroughly after each addition until the cheese is melted and the sauce is smooth.
- Adjust Consistency: Taste the sauce and adjust salt/spice levels. If the sauce is too thick, whisk in a tablespoon of the reserved pasta water at a time until you achieve a luxurious flow.
- Combine and Serve: Add the cooked macaroni to the sauce. Stir gently until every piece of pasta is coated in the golden sauce. Serve immediately while hot.
