This mushroom pasta with old-fashioned cream sauce combines sautéed mushrooms, chicken broth, heavy cream, and pecorino romano cheese with tender egg noodles to make a smooth, well-balanced pasta dish entirely from scratch.
Heat olive oil in a pan over medium heat and cook the chopped onion until softened and semi-transparent without browning.
Add the mushrooms, pressed garlic, salt, pepper, and thyme, cooking until the mushrooms are lightly tender and have released some of their juices.
Sprinkle the flour evenly over the mushroom mixture and stir continuously for about 1 minute to cook off the raw flour taste.
Slowly add the chicken broth and bring to a gentle simmer, cooking just until the sauce begins to thicken slightly while remaining loose.
Stir in the heavy cream and pecorino romano, heating gently until the cheese melts and the sauce is smooth, then remove from heat and rest for 5 minutes.
Pour the sauce over the cooked egg noodles in a large bowl and toss well until evenly combined.
Garnish with parsley and smoked paprika before serving, if desired.
Notes
Use freshly grated cheese: Grate the pecorino romano yourself so it melts smoothly into the sauce without clumping or graininess.
Keep the sauce loose: Stop thickening the sauce early, as it will continue to settle slightly while resting and once combined with the noodles.
Warm noodles matter: Toss the sauce with freshly cooked, warm egg noodles so it coats evenly and combines properly.
Taste before salting: Pecorino romano adds salt, so adjust seasoning only after everything is fully combined.
