Ten ingredients and thirty-five minutes in one skillet and one pot.
There is no tomato in this at all. The red flecks are pepper flakes, and the sauce stays pale.
Why This Recipe Works
- Draining the fat after browning keeps a cream sauce from turning greasy.
- Rigatoni's ridges and wide tubes hold a thin sauce better than a smooth shape.
- Parmesan thickens the cream without any flour.
- Starchy pasta water is what lets a thin sauce cling rather than slide.
- Butter added at the very end gives gloss that a simmer would cook away.
Ingredient Notes
- Rigatoni
- Twelve ounces. Wide ridged tubes — the shape matters here even though the title says only pasta.
- Lean ground beef
- A pound, browned in crumbles to 160 degrees Fahrenheit. Lean matters because the fat is drained and a cream sauce follows.
- Red pepper flakes
- Half a teaspoon. These are the small red flecks in the finished bowl — there is no tomato anywhere in this recipe.
- Butter, divided
- Three tablespoons: two into the sauce with the garlic, one stirred in at the very end for gloss.
How to Make It
Rigatoni al dente, a cup of water kept
Cook the rigatoni in salted water until al dente; reserve 1 cup pasta water and drain.
Beef browned in crumbles to 160°F, fat drained
Brown the ground beef in a large skillet, breaking it into crumbles, until it reaches 160°F; drain excess fat.
Butter, garlic, then cream and the flakes
Add 2 tbsp butter and the garlic; cook 30 seconds, then stir in cream, salt, pepper, and red pepper flakes.
Parmesan in until pale and lightly thickened
Simmer 3 to 4 minutes, then stir in Parmesan until the sauce is pale and lightly thickened.
Pasta in, water to a sauce that clings
Add the rigatoni and enough reserved pasta water to make a thin sauce that clings without pooling.
Last butter and parsley
Finish with the remaining butter and parsley and serve hot.
Aiming for a Sauce That Clings
The target is unusual: a sauce that CLINGS WITHOUT POOLING, explicitly NOT a heavy alfredo. That is harder than making it thick, because every rung below either adds body or takes it away, and the recipe deliberately does both.
Reserve a FULL cup of pasta waterBefore draining
12 oz of rigatoni cooked al dente, and 1 CUP of the water kept back. A cup is a lot to reserve for six servings and it is not an accident: the sauce is built thick and then let down, so most of this gets used. The dissolved starch in it is the only emulsifier here - there is no flour anywhere in the recipe.
Brown the beef, then TAKE THE FAT AWAY160F, then drain
1 lb of LEAN ground beef broken into CRUMBLES and browned UNTIL 160F, then the EXCESS FAT DRAINED. Two decisions pulling the same way. Lean beef and drained fat both keep rendered grease out of what is about to become a cream sauce - fat and cream together turn greasy rather than rich. 160F is the safe temperature and it is reached here, in the pan, before any liquid arrives.
Garlic 30 seconds, then cream and the flakes30 seconds of garlic
2 TBSP of the butter with 4 cloves of minced garlic for THIRTY SECONDS, then 1 cup heavy cream, 3/4 tsp salt, 1/2 tsp pepper and 1/2 TSP RED PEPPER FLAKES. The small red specks in the sauce are those chilli flakes, NOT sun-dried tomato - this recipe carries no tomato at all.
Parmesan for body, no flourPale and lightly thickened
Simmered 3 to 4 minutes, then 1/2 cup of finely grated Parmesan stirred in UNTIL PALE AND LIGHTLY THICKENED. LIGHTLY is the instruction. The cheese is the only thickener in the dish, and the target is not a coating sauce yet - it is a sauce with enough body to survive being thinned in the next rung.
Let it DOWN with the pasta waterA splash at a time
The rigatoni added with ENOUGH RESERVED PASTA WATER TO MAKE A THIN SAUCE THAT CLINGS WITHOUT POOLING. This is the rung the whole ladder exists for, and it runs backwards from instinct: having just thickened the sauce, you thin it. Starchy water thins WITHOUT losing grip, which is what separates a sauce that coats every ridge of a rigatoni tube from one that sits in the bottom of the bowl. Add it a splash at a time. Then the LAST TBSP of butter off the heat for gloss, and 1/4 cup of parsley.
Success Tips
- Drain the fat properly after browning or the cream sauce turns greasy.
- Add the pasta water a splash at a time — you want it clinging, not soupy.
- Save the last tablespoon of butter for after the heat is off.
Serving Ideas
Six servings in white bowls, the ridged rigatoni and browned beef crumbles in a thin pale cream that coats every tube, heavily scattered with chopped flat parsley and red pepper flakes.
Frequently Asked Questions
Are the red flecks sun-dried tomato?
No — they are red pepper flakes. There is no tomato in this recipe, which is part of why the sauce stays pale.
Does the pasta shape matter?
Rigatoni. Its ridges and wide tubes hold a deliberately thin sauce that would slide off a smoother shape.
My sauce looks thin — is that right?
Yes. It is meant to cling to the pasta rather than pool in the bowl. This is not a heavy alfredo.
