Creamy Mushroom Pasta Sauce with Crème Fraîche
This post may contain affiliate links. Please read my disclosure policy.
There’s a version of mushroom pasta that’s beige and forgettable, and then there’s this one. The difference? Mushrooms that start with an undisturbed sear in a hot pan — no stirring or rushing — before shallots, thyme, and a pinch of red pepper enhance the rest of the sauce. Using crème fraîche instead of heavy cream makes this rich and tangy pasta a meal in 25 minutes.
Why This Recipe Works
- The no-stir mushroom sear is the game changer: Leaving mushrooms undisturbed in a hot pan for several minutes builds the kind of deep, nutty browning that merges into the sauce the moment you add liquid.
- Crème fraîche instead of heavy cream: It has a natural tangy flavor that cuts through the richness, and it doesn’t break or curdle the way heavy cream can when you add lemon juice or pasta water.
- Chunky mushrooms. Torn — not thinly sliced — mushrooms have irregular edges that catch the sauce and brown more aggressively than sliced ones — more surface area equals more flavor.
For a deeper, longer-cooked mushroom sauce, this bolognese sauce with mushrooms is what you’re looking for.
Ingredients I reach for
- Mushroom mixture: For body and depth, I use a half-and-half mix of cremini (also labeled “baby bella”) and white button mushrooms. Button mushrooms are milder and release liquid more quickly, while the cremini are denser and earthier in flavor. You can go all cremini for a more robust result, or substitute a portion with shiitake or oyster mushrooms — both hold up well in a hot pan and add complexity (case in point: these garlicky sautéed oyster mushrooms). Avoid portobello caps. They’ll bleed into the sauce and turn it gray. Whichever variety you use, tear them rather than slicing — the irregular surfaces brown better and gives the sauce more to cling to.
- Creme fraiche: I don’t like to use flour as a thickener because it can make the sauce pasty and unpleasantly starchy. Enter crème fraîche, a type of cultured cream — richer than sour cream, tangier than heavy cream — with a high fat content that makes it stable. You can add lemon juice directly to crème fraîche without worrying about it breaking. The flavor it contributes is buttery with a faint cultured sourness and it rounds out the earthy taste of the mushrooms without covering them up. It keeps for weeks in the coldest part of the refrigerator, so it’s worth having on hand.
- Thyme: An herb that actually gets better with heat — the leaves release a piney, faintly smoky flavor as they cook with the shallots and garlic, and their woodsy quality turns out to be a natural match for mushrooms in an even better way than softer herbs like parsley. I use a full tablespoon. If you only have dried, decrease to a teaspoon.
Why you shouldn’t stir the mushrooms (at first)
Add the mushrooms to a large skillet over medium-high heat in a single layer. Five minutes of undisturbed contact with a hot pan is the key to getting good caramelized browning — if you stir too soon they’ll steam instead of sear.
Once the mushrooms are browned, add salt, shallot, garlic, thyme, and red pepper. The salt draws out moisture immediately, softening the shallots and lifting all the brown bits from the pan. Add the crème fraîche — it will liquify in about 30 seconds. Simmer a minute or two with some pasta water to make the sauce.
Add the cooked pasta directly to the pan over low heat. The starchy pasta water, mushrooms, and pasta marry into a cohesive sauce. The light cream sauce and grated Parmesan coats the pasta when you toss directly in the skillet.
Creamy Mushroom Pasta Sauce with Crème Fraîche
A 25-minute mushroom sauce with chunky browned mushrooms, shallots, thyme and creme fraiche. Toss with linguine, fettuccine, or spaghetti or short cuts like rigatoni or penne.
Ingredients
- 1½ pounds white button or cremini mushrooms, or a mixture of both
- Kosher salt
- ½ pound fettuccine or linguine pasta
- 3 tablespoons extra virgin olive oil
- ¼ cup finely chopped shallot
- 1 tablespoon minced garlic
- 1 tablespoon chopped fresh thyme, or 1 teaspoon dried thyme
- ¼ teaspoon crushed red chili flakes
- ¾ cup creme fraiche or heavy cream
- 1 tablespoon chopped fresh parsley
- 2 teaspoons fresh lemon juice
- ¼ cup freshly grated Parmesan cheese
Instructions
- Prepare the mushrooms: Trim the stems off 1½ pounds white button or cremini mushroomss. Tear the caps into generous bite-sized pieces – you want a rustic, chunky texture.
- Bring a large (5-6 quarts) water to a boil along with 4 tablespoons kosher salt (or use 1 ½ tablespoons regular table salt). Cook ½ pound fettuccine or linguine pasta according to package directions, until al dente. Before draining the pasta, scoop out 1 cup of the cooking water and reserve.
- While the pasta cooks, heat 3 tablespoons extra virgin olive oil in a large (12-inch) skillet (preferably nonstick) over medium-high heat. Add the mushrooms to the pan and spread them out in one layer. Cook 5 minutes without stirring. Give the pan a shake and stir the mushrooms around. Cook another 5 minutes.
- At this point, the mushrooms should be taking on some color and releasing some liquid. Add 1 teaspoon salt, ¼ cup finely chopped shallot, 1 tablespoon minced garlic, 1 tablespoon chopped fresh thyme and ¼ teaspoon crushed red chili flakes and stir well. Cook until the shallots are softened, about 2 minutes.
- Add ¾ cup creme fraiche or heavy cream and 1 tablespoon chopped fresh parsley to the mushrooms. Gently simmer until the sauce thickens. Add ⅓ cup of the reserved water and 2 teaspoons fresh lemon juice and stir, scraping the pan to release any browned bits.
- Put the cooked pasta in the pan and use tongs to toss in the sauce. Add a bit more pasta water if the sauce seems dry. Remove from the heat, sprinkle with ¼ cup freshly grated Parmesan cheese and serve.
Karen’s Notes and Tips
- Heavy cream instead of creme fraiche: The sauce will be richer, but less tangy. Also, heavy cream can break when acid hits it at high temperature — stir in the lemon juice off the heat.
- Make it vegan: Replace crème fraîche with full-fat oat cream or cashew cream (not oat milk — it’s too thin and will break). Omit the Parmesan or substitute a non-dairy version.
- Variations: Toss in a few large handfuls of spinach leaves after the mushrooms are cooked and let them wilt before adding the cream. Bacon or pancetta: Cook about 6-8 ounces separately until crisp, and use the rendered fat in place of some of the olive oil. Add it back to finish the dish with the pasta.

Creme fraiche curlded and separated leaving just a nasty looking liquid.
Ahh Kevin, I’m so sorry that happened! Creme fraiche is more stable than heavy cream and shouldn’t curdle so readily. I think what may have happened is that your sauce simmered a touch too long, or perhaps was nearer to a boiling temperature (it should be a gentle simmer). I will adjust the directions to make that clearer for everyone.
Even though I forgot the garlic I chopped, it was still a really flavorful Mushroom pasta. I used the creme fraiche which I needed to use up and added the bacon bits and spinach so it was a perfect pasta meal. I love when I can use my herbs and lemons from my garden. I have always chopped my mushrooms and this was a new experience to just tear the Cremini mushrooms in large chunks. My husband had seconds…..Thanks!
This recipe was good, but SUPER salty! I don’t think the pasta water requires that much kosher salt. I’ll make it again, but reduce the salt by half.
Hi Jody! When properly salted, pasta water should be seasoned with about 1 tablespoon kosher salt per quart of water. Is it possible your pot is smaller than 6 quarts?
I loved the simplicity of this recipe. It was thoroughly delicious and devoured!! Just a note to say lately I’ve been browning mushrooms without oil or anything and they turn out beautifully. Thank you for the awesome recipe!!
I’m happy you enjoyed it Christine! Yes, the cool thing about mushrooms is that they release water at a certain point during cooking, which helps keep them from sticking to the pan after browning 🙂
The BEST, thank you, thank you!!!!
Perfect for me! Delicious said my guests! Thank you, happy with your recipe.
I just added some beyond meat for annexeren bite 🙂
LOVED this, added just a bit of truffle oil to my plated portion, and that took the bright, earthy flavor to a whole other level. Fabulous!
To make this vegan, what do you suggest using for the cream? Would coconut cream suffice? Would the flavor change to more coconut taste?
Hi Linda, I suggest using full-fat oat milk. Coconut milk will result in a similar consistency to the the cream, but it does have a distinct taste. Hope that helps!
I just made this tonight and it’s freaking amazing!!! The chopped bacon on top was a definite plus
Happy you enjoyed the pasta Peggy!
I made this last night to go with some seared scallops. I intended to make it exactly as written, but somehow I missed the parmesan. It was wonderful anyway, but the next time I make it (and there will definitely be several next times!), I will add the cheese. Everyone loved it.
I LOVE this recipe! It’s fast, easy and delicious. Thank you for sharing it😘
