A quick and easy vegetarian pasta recipe — pappardelle with portobello mushrooms and rosemary.
A meaty portobello mushroom sauce combined with ribbons of al dente cooked pasta noodles make this a very satisfying plate, and you can make it on the fly. This is by far one of our most popular pappardelle pasta recipes!
The sauce is much like a traditional ragu or Italian meat sauce, except it’s meatless.
It’s perfect with dishes like soft, cheesy polenta as well as over pasta – of course!
Portobello mushrooms with pasta
Portobello mushrooms have abundant earthy, woodsy flavors that match up perfectly with the piney, aromatic fresh rosemary, garlic cloves and red pepper. The caps are big and meaty, which means portobellos are great for stuffing, as well as roasting with garlic and herbs.
And with pasta, thick mushroom ragus and tomato sauces like this one are best mates with pappardelle — the flat, wide strands coil and curl easily around a fork, catching all the juices and chunky bits of sauce. Yum!
What are portobello (or portabella) mushrooms?
Portobello mushrooms (or portabellas) are actually overgrown, giant cremini mushrooms. It’s true!
Portobellos became all the rage in the 1990s, when mushroom growers realized the potential in allowing white button mushrooms to mature a few extra days.
First they’re marketed as “baby” portobellos called “cremini” before growing into the oversized beauties we call portobellos.
How to prepare portobello mushrooms:
- Choose firm mushrooms with unbroken caps.
- Wipe the mushrooms gently with a towel if they seem dirty — don’t soak them in water or they’ll become soggy.
- The underside of the mushrooms, or the gills, should be tight, dry and light brown in color.
- Yes, you can eat the gills of portobello mushrooms. But if they look very dark in color and moist (verging on slimy) you can feel free to remove them or they might make the sauce murky.
- If the gills are moist and/or turning black, scoop them out with a spoon and discard before slicing and cooking over medium-high heat.
Is pappardelle the same as egg noodles?
Pappardelle is a pasta cut into wide, long noodles. You can find it as fresh egg pasta, and it’s also available as a dried egg pasta and durum wheat pasta without eggs.
The nice, chunky size of pappardelle noodles means it’s ideal to in pasta dishes with rich, hearty sauces like this mushroom ragu, or with creamier sauces like the sauce in Pappardelle al Limone.
I reserve thinner pasta cuts such as spaghetti and linguine for dishes like crowd-pleasing pasta carbonara.
