Why I love this recipe

Most people cook mushrooms the wrong way, resulting in a slimy and watery texture. However, my secret to achieving the best flavor is taking the time to thoroughly brown and caramelize them. This simple, often overlooked, step will have a huge impact on your vegan mushroom pasta recipe.

Once cooked, the mushrooms are coated in a lusciously creamy, umami-rich sauce and tossed with al dente pasta. All you need is a stockpot and a skillet, and you’ll have a gourmet-tasting dish that’s ideal to make at the end of a long workday for the whole family.

Ingredient notes

There are few ingredients in this creamy vegan mushroom pasta, but each one plays a pivotal role! Here’s a breakdown of what you’ll need.

Pasta
You can use any pasta you prefer, though I recommend choosing shapes that hold sauce well, like fettuccine or bucatini. You can also use short pasta, like fusilli or cavatappi.

Substitute: Any gluten-free pasta brand can be used for a gluten-free version. The texture will vary slightly but still be delicious.

Mushrooms
I like to stick to cremini mushrooms since they’re one of the most widely available and affordable varieties on the market. If you’re looking to create more layers of flavor and texture, opt for a variety of mushrooms. Think shiitake, oyster, chantarelle, portobello, etc.

All-purpose flour
Instead of heavy cream or cashews, I use all-purpose flour to thicken the sauce, giving it a lusciously smooth consistency while keeping things more affordable.

Substitute: For a gluten-free option, use ½ tablespoon of cornstarch mixed with 1 tablespoon of cold water. Add the cornstarch slurry after you’ve added the soy milk.

Soy milk
Soy milk forms the base of the sauce in place of heavy cream or milk, adding smoothness without overpowering the mushroom flavors.

Substitute: I prefer the consistency and protein content of soy milk, but you can use almond, cashew, or coconut milk.

Nutritional yeast
Brings a cheesy, umami richness, crucial for adding depth to the sauce.

Substitute: Miso paste makes a good replacement for nutritional yeast, providing an even deeper umami flavor.

Lemon
I like to use both the zest and juice to add brightness and a tangy contrast to the creamy sauce. Plus, it’s a great way to reduce food waste!

How to make

Learn the best way to make vegan mushroom pasta with my straightforward, easy-to-follow instructions. Look for the tips in green throughout this section for consistent and successful results!

Preparation

Gently rub the mushrooms with a damp towel to remove dirt without soaking them. Finely mince the garlic, then zest and juice the lemon.

NEVER fully submerge mushrooms in water, as they are very porous and absorb water like a sponge. If you rinse or submerge them, dry them with a towel the best you can and add a few minutes to their cooking time.

Cooking

Step 1
Cook the pasta in salted boiling water as per the package instructions. Aim for an al dente texture, as the pasta will continue to cook when it’s tossed with the sauce.

When I say salted water, it should taste like seawater. This is your only chance to infuse the pasta with flavor, so don’t skip it.

Step 2
In a large skillet, heat the olive oil over medium-high heat. Add the mushrooms, making sure they have enough space. Sauté them until they’re golden brown and their moisture evaporates.

The Maillard reaction (aka browning) is one of the keys to delicious mushrooms. Keep them over medium-high or even high heat to properly brown them without steaming.

Step 3
Add minced garlic to the skillet, stirring until just aromatic. Keep a close eye on the pan to prevent burning, which can introduce a bitter taste.

Step 4
Sprinkle flour over the mushrooms to create the roux that will thicken the sauce. Slowly incorporate the soy milk, stirring continuously to prevent lumps. Add the lemon zest and juice last.

Step 5
Combine the cooked pasta with the mushroom sauce, adding reserved pasta water to achieve the perfect consistency.

The pasta water is rich in starches released during cooking, acting as an emulsifier that helps the sauce cling to the pasta and not become overly thick.

Step 6
Season the pasta with salt and pepper to taste, then serve it immediately with fresh parsley and vegan Parmesan on top. Happy eating!

Serving suggestions

For a filling and traditional side dish, serve your vegan mushroom pasta recipe with a slice of vegan garlic bread or dairy-free bread.

If you’re looking for a healthier option, try an apple walnut salad or kale Caesar salad to complement its richness and make a well-balanced meal.

Cooking tips

Time the garlic: Add garlic only after the mushrooms have started to brown. Garlic burns quickly and adding it later preserves its flavor without the risk of charring.

Soy milk temperature: Before adding the soy milk, make sure it’s at room temperature. Sudden temperature changes can affect the sauce’s consistency.

Control the heat: Maintain a gentle simmer when cooking the sauce to prevent it from splitting or becoming grainy.

Frequently asked questions

Storing & reheating

While pasta is best enjoyed immediately, this vegan mushroom pasta stores surprisingly well! Let the leftovers cool down to room temperature to prevent moisture build-up.

Fridge
Vegan mushroom pasta can be stored in the fridge for up to 3-4 days. Place it in an airtight container to maintain its freshness and prevent absorbing other food odors.

Freezer
Although freezing is possible, it will significantly alter the texture of the pasta and mushroom. If you choose to freeze it, do so in a freezer-safe container for up to a month.

Reheating
The best method to reheat is on the stovetop over medium heat, adding a splash of reserved pasta water, regular water, or plant milk to loosen the sauce.

Serving size

This vegan mushroom pasta recipe comfortably serves 4 people, making it perfect for family dinners or small gatherings.

If you’re hosting a large group of people and want to double or triple the recipe, I recommend cooking the mushrooms in batches to prevent a soggy texture. You can even cook them in advance, then reheat them and carry on with the rest of the recipe.
