Ten ingredients and forty-five minutes, with a sauce built in the same pan the pasta will be coated in.
The rigatoni comes out of the water deliberately underdone. It has twenty more minutes in the oven, and pasta boiled to al dente first arrives at the table soft.
Why This Recipe Works
- Boiling shy of al dente leaves room for the pasta to finish in the oven.
- Cooking the garlic thirty seconds takes its raw edge without browning it.
- Simmering pumpkin and cream together three minutes thickens the sauce properly.
- Whisking Parmesan in off the boil keeps the sauce smooth rather than grainy.
- A mozzarella blanket browns in patches in a way a covered pot cannot.
Ingredient Notes
- Rigatoni
- Twelve ounces. The large tubes are what the finished dish shows, and their ridges hold a thick sauce better than a smooth shape would.
- Pumpkin puree
- One cup. This is the entire source of the orange colour — there is no squash, carrot or tomato anywhere in the recipe.
- Shredded mozzarella
- A cup and a half, over the top rather than stirred through. It is the blanket that browns in patches in the oven.
- Grated Parmesan
- Three quarters of a cup into the sauce, plus more to serve. The extra at the table is part of the recipe, not an afterthought.
How to Make It
Oven to 400°F, a rectangular dish greased
Heat oven to 400°F and grease a rectangular baking dish.
Rigatoni boiled just shy of al dente, drained
Boil rigatoni until just shy of al dente; drain.
Butter, garlic, then pumpkin and cream simmered three minutes
Melt butter, cook garlic 30 seconds, then whisk in pumpkin and cream; simmer 3 minutes.
Parmesan whisked in, the rigatoni coated in orange sauce
Whisk in Parmesan, salt, and pepper until smooth, then coat the rigatoni in the orange sauce.
Into the dish under mozzarella, baked to browned patches
Transfer to the dish, cover with mozzarella, and bake 18 to 22 minutes until browned in patches.
Parsley scattered, extra Parmesan alongside
Scatter with parsley and serve with extra grated Parmesan.
Building the Orange, One Addition at a Time
There is no squash, no carrot and no tomato in this dish, and no meat or vegetable pieces of any kind. Everything the finished bake looks like comes out of one saucepan, built in a fixed order over about four minutes - and each addition is doing something the one before it could not.
Fat first
2 tbsp unsalted BUTTER, melted
The medium everything else is built in. Butter rather than oil because this is an alfredo-style sauce and its flavour is part of the base rather than just a way to stop things sticking.
30 seconds, no longer
2 cloves of GARLIC, minced
Long enough to lose the raw edge, short enough not to colour. Garlic browned in butter turns bitter, and there are only two cloves in six servings to carry it - so this is a half-minute step with a hard stop, not a soften-until-golden one.
The colour arrives
1 cup PUMPKIN PUREE and 1 cup HEAVY CREAM, whisked in and SIMMERED 3 MINUTES
This is the whole of the orange. The three-minute simmer is not optional standing time: puree whisked into cream and served straight away is thin and tastes raw, and three minutes both thickens it and cooks the puree's edge off. Whisked rather than stirred, so the puree disperses instead of sitting in streaks.
Off the hard boil
3/4 cup finely grated PARMESAN, 1/2 tsp salt, 1/4 tsp black pepper, whisked UNTIL SMOOTH
The thickening and the savoury backbone. Finely grated so it melts rather than clumping, and whisked in until smooth is a stated endpoint - Parmesan dropped into a sauce at a rolling boil seizes into grains that never come back together.
The pasta joins the sauce, not the other way round
12 oz of RIGATONI, boiled JUST SHY OF AL DENTE and drained
Coated in the pan so every tube carries sauce inside and out. Shy of al dente is deliberate: there are 18 to 22 minutes of oven still to come, and pasta that was already done when it went in arrives soft.
Then tasteInto a greased rectangular dish, covered with 1 1/2 cups of MOZZARELLA - over the top, never stirred through - and baked at 400F for 18 to 22 minutes UNTIL BROWNED IN PATCHES. That browned blanket is the thing a slow cooker cannot produce. Then 2 tbsp of chopped PARSLEY, and EXTRA GRATED PARMESAN at the table as part of the serving rather than an optional extra.
Success Tips
- Pull the pasta a minute early; it keeps cooking in the sauce and again in the oven.
- Take the sauce off a hard boil before the Parmesan goes in or it turns grainy.
- Watch for browned patches rather than a timer — 400°F ovens vary at the top.
Serving Ideas
Six servings from a rectangular dish, large rigatoni tubes in a thick orange sauce under melted cheese browned lightly in places, scattered with chopped parsley, with a small bowl of grated Parmesan alongside.
Frequently Asked Questions
What makes it orange?
A cup of pumpkin puree in the sauce. There are no vegetable pieces and no meat in the dish — the colour is entirely the sauce.
Why boil the pasta underdone?
It has eighteen to twenty-two more minutes in a hot oven. Boiled to al dente first, rigatoni comes out of the bake soft.
Can another pasta shape be used?
The recipe uses rigatoni, and the ridged tubes are what the finished bake shows. A smaller shape holds much less of a sauce this thick.
