Olive oil and pasta… a match made in heaven!
It’s no secret that olive oil and pasta go together like bread and butter. And that’s part of why this recipe has always been a no brainer kind of dish in our household.
Truth be told, I’ve been making this pasta for years but haven’t had the time to put down on paper… until now thanks to my friends at O-Live & Co.
This vegetarian mushroom pasta takes your standard cream based white sauce and amps it up a level with caramelized mushrooms, peas, arugula, and some lemon juice. It’s a guaranteed crowd pleaser and comes together on your dinner table in under 30 minutes.
Another reason this dish is a favorite in our kitchen is because of how easy it is to mix up!
If you don’t have mushrooms or peas you can easily substitute them with whatever veggies you have on hand. Asparagus, broccoli and zucchini are some of my favorites.
Once your veggies are cooked to your liking (we’re caramelizing the mushrooms and keeping the peas raw but you could roast or air fry too), it’s as easy as folding them into the sauce with your pasta and that’s it!
How to make a thick, creamy white sauce
Whenever I make a variation of this dish, my friends and family are always in awe of how quickly the creamy white sauce comes together.
Some call it alfredo, others call it a meatless carbonara, but I like to keep it simple and call it like I see it: creamy white sauce.
It really is quite impressive how fast it is to make; we’re talking 5 minutes or less.
There are a few ingredients and steps that will ensure your sauce comes out perfectly thick and creamy every time.
Start by melting some butter with your olive oil in a saucepan. Toss in some minced garlic as soon as the butter is melted and brown the garlic over medium heat. The garlic will add a great deal of flavor to the sauce, and is not to be skipped!
Next, sprinkle some flour over the butter, oil and garlic. You can use all purpose flour or your favorite gluten free flour blend. This step helps to create thickness in your sauce. Cook the flour and oil and garlic for a few minutes, stirring with a whisk.
Continue to whisk while you add in the veggie stock. Continue to whisk while you add in the heavy cream. Finally, turn off the heat and whisk in the salt, pepper, nutmeg and parmesan cheese.
And just like that, you’ve made a creamy dreamy white sauce that will take any pasta to the next level. If you wanted to be really bad here, you could get crazy with the parmesan cheese. Not saying you should… just saying you could.

O-Live & Co. Organic Olive Oil
By now I’m hoping you’ve had a chance to check out O-Live & Co. and their Organic Olive Oil (my personal favorite). Their oil is fantastic for cooking with, drizzling raw on top of a crusty slice of bread or over a beautiful bowl of mushroom pasta.
Not to mention, O-Live has won multiple awards and scored 97/100 points in the Flos Olei rankings, the world’s most prominent olive oil ranking. This is no surprise considering how delicious their oil is to work with.
It’s been a true honor partnering with this brand over the last year; I hope you take the time to check them out and try out their oils as they have supported this small business in what was a challenging year.

Thank you for showing how peas can work in pasta. I remember telling other people that I used peas, and I was met with raised eyebrows. If only they knew!
